The objective is to provide single patient experience in a patient with anterior spinal artery syndrome in vasculitic neuropathy. This work is a single patient observation. Standard methods for blood tests, nerve conduction velocities (NCV), ultrasound, MRI, CSF studies, muscle and nerve biopsy were used. Anti- PR3 ANCA was used for measuring disease activity. A 56-year-old female patient was admitted with a progressive sensorimotor neuropathy. Guillain- Barre syndrome was suspected and IVIG treatment with 0.4g/kg body weight for 5 days was performed. Following a short period of improvement she experienced severe neuropathic pain radiating unilaterally from the brachial plexus and asymmetrically in both legs. Although the rather symmetric motor dysfunction was unusual for vasculitic neuropathy, the neuropathic pain syndromes were suggestive. Anti- PR3 ANCA was highly elevated with 608 U/ml (<5 U/ml). The sural nerve biopsy showed inflammatory lymphocytic infiltrates but did not allow any further classification. Apart from reduced renal function, no other organ involvement could be detected. NCV now showed asymmetric axonal nerve lesions, compatible with a multifocal neuropathy. Ultrasound demonstrated short segmental thickening of several peripheral nerves (median, ulnar, peroneal, tibial and sciatic). Perception of joint movement of the upper and lower extremities was severely reduced, walking felt like "walking on clouds". Steroid therapy was initiated but the disease progression could not be halted. The patient experienced a painless sigma perforation and hemicolectomy was performed. Prednisolone therapy was drastically reduced to allow wound healing. 4 weeks later she reported dramatic and painful worsening of her condition. She experienced further pain in both hands and legs as well as an autonomic dysregulation with hypotonia. The coordination of both hands fingers was further reduced, lower extremities were paraplegic, she had a possible sensory level at TH6, and light touch on lower extremities had an allodynic spread. MRI studies of the cervical and thoracic spine were repeated which showed a ventral medullar signal alteration from C5 to TH3 resembling the vascular distribution of the spinal anterior artery. In addition to steroids now several cycles of rituximab 375 mg/m2 once weekly were given and further long term treatment with azathioprine was initiated. This therapy had an effect on the anti-PR3 ANCA which was declining (110 U/ml). Still she has remained bedbound with proximal muscle activity but distally absent nerve conduction velocities in upper and lower extremities. This case provides several differential diagnostic difficulties: 1) the rather symmetric onset of an acute neuropathy resembling GBS, 2) the pattern of vasculitis not allowing any further histological classification, 3) the painless perfora tion of the sigma as possible sign of autonomic involvement and 4) a rare anterior spinal cord infarction in a patient with severe neuropathy, which was difficult to asses, as the vasculitic neuropathy concealed the symptoms of spinal cord infarction. Acute anterior spinal infarction appearing in vasculitic neuropathy is rare and is difficult to detect in a severe case of neuropathy.

The aim of the study was to verifythe decline in IENFD on serial measurement, that is stil lacking, and to correlate the small fiber loss with the large fiber neuropathy, myopathy and encephalopathy. Patients and methods: We enrolled 11 adult neurocritical care patients with no previous history or risk factors for neuromuscular disease who underwent serial skin biopsy together with evaluation of consciousness (including daily assessment of the Confusion Assessment Method for the Intensive Care Unit), sensory functions, muscle strength usinm MRC score (in cooperative patients), nerve conduction study and needle electromyography, and autonomic dysfunction using spectral analysis of heart rate variability. Development of infection, sepsis and multiple organ failure was recorded throughout the ICU stay. IENFD was assessed at the onset of critical illness, mostly within 24 hours (up to 3 days after the onset, median: 1st day) at the distal site of the right leg, and compared with values obtained from the left leg within 10-14 days (median: 13 days) after the first examination. Results: Of the 11 patients recruited, 9 (82%) had sepsis or multiple organ failure. Initially, 2 patients (18 %) had abnormal IENFD (median: 5.05 fibers/ mm) and showed significant decrease with abnormal IENFD in 8 patients (73%) on the second evaluation (median: 2.18 fibers/mm; p < 0.001). Signs of critical illness myopathy and/or neuropathy was found in 6 patients (55%), signs of autonomic dysfunction in 3 patients (2%) and signs of septic encephalopathy manifested as an episode of delirium in 7 cases (64%). Conclusions: Serial IENFD measurement showed the evidence ofvery frequent sensory small-fiber involvement in the acute phase of critical illness. Loss of sensory small fibers is an inseparable part of multiple involvement of neuromuscular system in critically ill patients representingan integral part of multiple organ failure in critically illpatients.

The mechanisms underlying this association remain unclear. This observational study investigated the effect of upper trapezius muscle pain on the distribution of upper trapezius activity during repetitive lifting. It was hypothesized that nociception would change the distribution of activity resulting in activation of muscle regions which would not normally be active during the task. Materials and Methods: Healthy men repeatedly lifted a box with a cycle time of 3 seconds for 50 cycles, at baseline, following injection of isotonic and hypertonic saline into the upper trapezius muscle and 15 minutes after the last injection. High-density surface electromyography (EMG) was recorded from the upper trapezius using a grid of 64 electrodes. The EMG amplitude was computed for each location to form a map of the EMG amplitude distribution. Results: During the painful condition, the overall EMG amplitude was lower compared with all other conditions (P<0.05) and in addition, the center of upper trapezius activity was shifted toward the caudal region of the muscle (P<0.01), a region not normally active during the task. The described alterations of muscle activity likely play an important role in the perpetuation of pain during repetitive activity. Discussion: Novel mapping of the spatial distribution of upper trapezius muscle activity showed that nociception induced a redistribution of activity during repetitive lifting. This knowledge provides new insights into the mechanisms underlying the perpetuation of pain with repetitive activity. Copyright © 2017 Wolters Kluwer Health, Inc. All rights reserved.

This study used muscle synergy analysis to investigate multiple forearm muscles in individuals with chronic elbow pain during the development of grip force. Eleven individuals with chronic elbow pain and 11 healthy age-matched control subjects developed grip force to 15% and 30% of maximum voluntary contraction (MVC). Surface electromyography was obtained from six forearm muscles during force development before nonnegative matrix factorization was performed. The relationship between muscle synergies and standard clinical tests of elbow pain were examined by linear regression. During grip force development to 15% MVC the pain group had a lower number of forearm muscle synergies, increased similarity in spatial activation patterns, increased cocontraction of forearm flexors, and a greater magnitude of muscle weightings across the forearm when performing the task. During the 30% MVC grip the numbers of muscle synergies were the same for both groups; however, the pain group had lower activation and reduced variability in the timing of peak activation. The timing of peak activation was delayed in the pain group regardless of the task, and performing the grip in different wrist postures did not affect muscle synergy characteristics in either group. Although localized pain causes direct dysfunction of an affected muscle, this study provides evidence that the timing and amplitude of agonist and antagonist muscle activity are also affected with chronic pain. NEW & NOTEWORTHY Muscle activation patterns of individuals with chronic elbow pain are simplified compared with healthy individuals. This is apparent as individuals with pain exhibit fewer forearm muscle synergies, and increased similarity of activation patterns between forearm muscles, when performing pain-free isometric gripping. As such, even during pain-free tasks it is possible to observe changes in motor control in people with chronic pain. Copyright © 2017 the American Physiological Society.

It is unclear if this is also true during functional locomotor perturbations such as changing direction, or if this change in coordination adaptability persists between symptomatic episodes. The purpose of this study was to compare trunk-pelvis coordination during walking turns in healthy individuals and asymptomatic individuals with a history of low back pain. Methods Participants performed multiple ipsilateral turns. Axial plane inter-segmental coordination and stride-to-stride coordination variability were quantified using the vector coding technique. Frequency of coordination mode and amplitude of coordination variability was compared between groups using Wilcoxon signed-rank tests and paired t-tests respectively. Findings During stance phase of the turn, there was no significant difference in either inter-segmental coordination or coordination variability between groups. Inter-segmental coordination between the trunk and the pelvis was predominantly inphase during this part of the turn. During swing phase, patterns of coordination were more diversified, and individuals with a history of low back pain had significantly greater trunk phase coordination than healthy controls. Coordination variability was the same in both groups. Interpretation Changes in trunk-pelvis coordination are evident between symptomatic episodes in individuals with a history of low back pain. However, previously demonstrated decreases in coordination variability were not found between symptomatic episodes in individuals with recurrent low back pain and therefore may represent a response to concurrent pain rather than a persistent change in motor control.

This morphological hip condition can cause joint pain, stiffness, impaired function, and eventually hip osteoarthritis. This exploratory study compared coordination of deep hip muscles between people with and without symptomatic FAI using analysis of muscle synergies (i.e., patterns of activity of groups of muscles activated in synchrony) during gait. Fifteen individuals (11 males) with symptomatic FAI (clinical examination and imaging) and 14 age- and sex-comparable controls without morphological FAI underwent testing. Intramuscular fine-wire and surface electrodes recorded electromyographic activity of selected deep and superficial hip muscles. A non-negative matrix factorization algorithm extracted three synergies which were compared between groups. Information regarding which muscles were activated together in the FAI group (FAI group synergy vector) was used to reconstruct individual electromyography patterns and compare groups. Variance accounted for (VAF) by three synergies was less for the control (94.8 [1.4]%) than FAI (96.0 [1.0]%) group (p = 0.03). VAF of obturator internus was significantly higher in the FAI group (p = 0.02). VAF of the reconstructed individual electromyography patterns with the FAI or control group vector were significantly higher for the FAI group (p < 0.01). Following reconstruction, VAF of quadratus femoris was significantly more reduced in controls (p = 0.04), indicating greater between-subject variability. Coordination of deep hip muscles in the synergy related to hip joint control during early swing differed between groups. This phase involves movement towards the impingement position, which has relevance for the interpretation of synergy differences and potential clinical importance. © 2016 Orthopaedic Research Society.

To clarify clinical polymorphism of amyotrophic lateral sclerosis (ALS). Material and methods. The study was based on records of a hospital personalized register. Ninety-four patients, aged from 25 to 81 years, diagnosed with ALS according to El Escorial criteria were included. Electromyography and, if necessary, transcranial magnetic stimulation and magnetic-resonance tomography were used to confirm the diagnosis. Disease progression was assessed with the ARSFRS. Age at disease onset, progression rate and duration of survival of patients, rare symptoms of ALS (<>), time for palliative care (gastrostomy, non-invasive and invasive lung ventilation) and provision of the care to the patient, family history were recorded in a specially designed questionnaire. Results. Most of the patients had sporadic ALS, only two familial cases were identified. Spinal onset ALS was found in 66.0% of the patients, bulbar onset in 29.8%, diffuse onset (spinal and bulbar motor neurons were affected simultaneously) in 4.2%. Moderate ALS progression was observed in 42.6% of the patients, mean time till death was 3.0 +/- 1.2 years. A slow progression was found in patients with cervical, low back and bulbar onset. A rapid and even <> type of progression was in diffuse and breast onset. An extremely slow progression with the long-term hospital treatment and survival >5 years was found in 9.7%. Rare ALS symptoms were represented by specific cognitive and psychological impairments, a type of frontal/temporal dysfunction, but only 5 (5.3%) patients were diagnosed with ALS-dementia. Signs of pathological muscle fatigue (myasthenic syndrome) were identified in 18 (19.1%), extrapyramidal disorders in 5 (5.3%), coordination disorders in 4 (4.3%), pain in 12 (12.8%), sensory symptoms in 5 (5.3%) of the patients. Conclusion. ALS is a multisystemic neurodegeneration disease though the progressive motor neuron death determines the fatal outcome. Copyright © 2017, Media Sphera Publishing Group.

Recent work has highlighted a strong relationship between eye and neck muscle activation in pain-free subjects. It is possible that WAD may disrupt the intricate coordination between eye and neck movement. Electromyographic activity (EMG) of muscles that rotate the cervical spine to the right (left sternocleidomastoid, right obliquus capitis inferior (OI), right splenius capitis (SC) and right multifidus (MF)) was recorded in nine people with chronic WAD. Cervical rotation was performed with five gaze conditions involving different gaze directions relative to cervical rotation. The relationship between eye position/movement and neck muscle activity was contrasted with previous observations from pain-free controls. Three main differences were observed in WAD. First, the superficial muscle SC was active with both directions of cervical rotation in contrast to activity only with right rotation in pain-free controls. Second, activity of OI and MF varied between directions of cervical rotation, unlike the non-direction-specific activity in controls. Third, the effect of horizontal gaze direction on neck muscle EMG was augmented compared to controls. These observations provide evidence of redistribution of activity between neck muscles during cervical rotation and increased interaction between eye and neck muscle activity in people with WAD. These changes in cervico-ocular coordination may underlie clinical symptoms reported by people with WAD that involve visual deficits and changes in function during cervical rotation such as postural control. © 2011 Springer-Verlag.

The aim of this study is to generate a set of recommendations to define and diagnose SFN in Brazil. A group of 13 neurologists, members of the Scientific Department of Peripheral Neuropathy from the Brazilian Academy of Neurology reviewed a preliminary draft prepared by the first author that was distributed by email. The panelists got together on 6.4.2017 at the city of Fortaleza, Brazil, to discuss and finish the text for the first submission of the manuscript. SFN can be defined as a subtype of neuropathy characterized by selective involvement of unmyelinated or thinly myelinated sensory (sometimes also autonomic) fibers. It is usually characterized by sensory (pain/dysesthesias/pruritus) or combined sensory and autonomic complaints, associated with an almost entirely normal neurological examination (except for sensory changes). Electromyography is normal. A growing list of medical conditions has been linked to SFN, although there is no evidence-based literature to support the use of any specific set of screening tests to diagnose the etiology of SFN (the panelists will suggest a basic screening panel). SFN may also serve as a fallacious but useful terminology to uncover discrepancies in the normal values from different neurophysiology laboratories. In Brazil, skin biopsy is not usually performed and initial forms of leprosy may have predominant small fiber involvement. There are several tests to demonstrate involvement of small sensory and autonomic fibers. Skin wrinkling test, sympathetic skin responses & heart rate variability (conducted on EMG machines) and thermoregulatory sweat test may be low-cost screening alternatives. After the final meeting on 6.4.2017, we finished the first draft for submission to Arquivos de Neuropsiquiatria (together with a translation to Portuguese as supplementary material), the official journal of the Brazilian Academy of Neurology to serve as a source for the definition and diagnosis of SFN in Brazil. The final draft will be submitted after presentation at the PNS Meeting in Barcelona on 7.2017.

Methods: Thirty female adults were allocated to one of two groups-healthy controls or cases with neck-shoulder pain. Surface electromyography (sEMG) signals from the clavicular, acromial, middle and lower trapezius portions and the serratus anterior muscles were recorded during a task performed for 20 min at a slow pace and 20 min at a fast pace. The root mean square (RMS), relative rest time (RRT) and normalised mutual information (NMI, an index of functional connectivity between two muscles in a pair) were computed. Results: No significant differences on RMS, RRT and NMI were found between groups. For both groups, the fast movement pace resulted in increased levels of RMS, lower degrees of RRT and higher NMI compared to the slow pace. No interaction between group and movement pace was found. Conclusions: This study highlights the change in sEMG activity of muscles to meet the demands of performing a task at fast movement pace. The fast pace imposed a higher muscle demand evidenced by increased sEMG amplitude, low degree of muscle rest and increased functional connectivity for subjects in both the case and control groups. No indication of impaired sEMG activity was found in individuals with neck-shoulder pain. Copyright © 2017 Elsevier B.V.

However, it is unclear whether these results can validly be transferred to suddenly applied walking perturbations, an automated but more functional and complex movement pattern. There is an evident need to develop research-based strategies for the rehabilitation of back pain. Therefore, the investigation of differences in trunk stability between H and BPP in functional movements is of primary interest in order to define suitable intervention regimes. The purpose of this study was to analyse neuromuscular reflex activity as well as three-dimensional trunk kinematics between H and BPP during walking perturbations. Methods Eighty H (31m/49f;29+/-9yrs;174+/-10cm;71+/-13kg) and 14 BPP (6m/8f;30+/-8yrs;171+/-10cm;67 +/-14kg) walked (1m/s) on a split-belt treadmill while 15 right-sided perturbations (belt decelerating, 40m/s2, 50ms duration; 200ms after heel contact) were randomly applied. Trunk muscle activity was assessed using a 12-lead EMG set-up. Trunk kinematics were measured using a 3-segment-model consisting of 12 markers (upper thoracic (UTA), lower thoracic (LTA), lumbar area (LA)). EMG-RMS ([%],0-200ms after perturbation) was calculated and normalized to the RMS of unperturbed gait. Latency (TON;ms) and time to maximum activity (TMAX;ms) were analysed. Total motion amplitude (ROM;[degree]) and mean angle (Amean; [degree]) for extension-flexion, lateral flexion and rotation were calculated (whole stride cycle; 0- 200ms after perturbation) for each of the three segments during unperturbed and perturbed gait. For ROM only, perturbed was normalized to unperturbed step [%] for the whole stride as well as the 200ms after perturbation. Data were analysed descriptively followed by a student's t-test to account for group differences. Co-contraction was analyzed between ventral and dorsal muscles (V:R) as well as side right:side left ratio (Sright:Sleft). The coefficient of variation (CV;%) was calculated (EMG-RMS;ROM) to evaluate variability between the 15 perturbations for all groups. With respect to unequal distribution of participants to groups, an additional matched-group analysis was conducted. Fourteen healthy controls out of group H were sex-, age- and anthropometrically matched (group Hmatched) to the BPP. Results No group differences were observed for EMG-RMS or CV analysis (EMG/ROM) (p>0.025). Co-contraction analysis revealed no differences for V:R and Srigth:Sleft between the groups (p>0.025). BPP showed an increased TON and TMAX, being significant for Mm. rectus abdominus (p = 0.019) and erector spinae T9/L3 (p = 0.005/p = 0.015). ROM analysis over the unperturbed stride cycle revealed no differences between groups (p>0.025). Normalization of perturbed to unperturbed step lead to significant differences for the lumbar segment (LA) in lateral flexion with BPP showing higher normalized ROM compared to Hmatched (p = 0.02). BPP showed a significant higher flexed posture (UTA (p = 0.02); LTA (p = 0.004)) during normal walking (Amean). Trunk posture (Amean) during perturbation showed higher trunk extension values in LTA segments for H/Hmatched compared to BPP (p = 0.003). Matched group (BPP vs. Hmatched) analysis did not show any systematic changes of all results between groups. Conclusion BPP present impaired muscle response times and trunk posture, especially in the sagittal and transversal planes, compared to H. This could indicate reduced trunk stability and higher loading during gait perturbations. Copyright © 2017 Mueller et al.

Fifteen participants performed a 4-min pedaling task at 130 W in two conditions (Baseline and Pain). Pain was induced by injection of hypertonic saline into the vastus medialis (VM) and vastus lateralis (VL) muscles of one leg. Force applied throughout the pedaling cycle was measured using an instrumented pedal and used to calculate pedal power. Surface electromyography (EMG) was recorded bilaterally from eight muscles to assess changes in muscle activation strategies. Compared to Baseline, during the Pain condition, EMG amplitude of muscles of the painful leg (VL and VM-the painful muscles, and RF-another quadriceps muscle with no pain) was lower during the extension phase [(mean +/- SD): VL: -22.5 +/- 18.9%; P < 0.001; VM: -28.8 +/- 19.9%; P < 0.001, RF: -20.2 +/- 13.9%; P < 0.001]. Consistent with this, pedal power applied by the painful leg was also lower during the extension phase (-16.8 +/- 14.2 W, P = 0.001) during Pain compared to Baseline. This decrease was compensated for by an 11.3 +/- 8.1 W increase in pedal power applied by the non-painful leg during its extension phase (P = 0.04). These results support pain adaptation theories, which suggest that when there is a clear opportunity to compensate, motor adaptations to pain occur to decrease load within the painful tissue. Although the pedaling task offered numerous possibilities for compensation, only between-leg compensations were systematically observed. This finding is discussed in relation to the mechanical and neural constraints of the pedaling task. Copyright © 2016, Springer-Verlag Berlin Heidelberg.

Easy bruising and bleeding are characteristic of the disorder but coagulation tests are generally normal. EDS type III (hypermobility type) is the least severe type of EDS. Rattlesnake venom in the southwest commonly has hemotoxic and cytotoxic effects; neurotoxic effects are less common. We report here a case of patient with EDS type III with severe envenomation who had neurologic symptoms, hematologic effects, and severe local effects. Case description: The patient is a 23-year-old female with a history of EDS type III who sustained rattlesnake envenomation to her right (dominant) hand. Initially she had severe swelling, bruising and pallor of the right arm and thrombocytopenia at 8000/mL. Approximately 2.5 h post-envenomation, the patient developed right eye droop and numbness of the right face. She underwent neuroimaging; CT and MRI were normal. She received 36 vials of CroFab during her initial hospitalization due to difficulty with control of arm swelling well as evolving neurologic complaints including R leg numbness and urinary retention. After 6 d in the hospital, she was discharged to a rehabilitation facility. Eight days after envenomation, she had a recurrent thrombocytopenia and received another four vials of CroFab. She had several subsequent presentations for continued nose bleeding, but with no laboratory abnormalities. She had persistent of symptoms of pain, discoloration, numbness, and decreased strength and mobility in her right arm. Two months after the envenomation, MRI showed localized subcutaneous soft tissue fibrosis of the dorsal R hand with underlying diffuse myositis of the first dorsal interosseous muscle. Three months after envenomation, nerve conduction studies were normal but EMG was abnormal suggesting myositis in the extensor carpi radialis longus. Repeat MRI 3.5 months after envenomation was again abnormal. The patient continued with multidisciplinary care with hand surgery, toxicology, rheumatology, occupational therapy, and a geneticist involved. Seven months after her envenomation, she continues to have limitation in the function of her right hand. Discussion: Both rattlesnake venom and EDS have significant individual variability. It is difficult to determine if this patient's EDS contributed to her complicated clinical course. The tissue fragility and bleeding as well as propensity for chronic musculoskeletal pain associated with EDS may have contributed to the morbidity of this patient's envenomation. Conclusions: In this case, an underlying collagen vascular disorder may have exacerbated the cyototoxic effects of rattlesnake envenomation.

On day one, subjects (N = 12) performed computer work with/without acute muscle pain induced in the trapezius muscle. Subsequently, eccentric exercise was performed to induce delayed onset muscle soreness (DOMS) in wrist extensor muscles. In presence of DOMS on day two, computer work recordings with/without pain were repeated. EMG signals were recorded from the descending part of trapezius bilaterally, flexor carpi ulnaris and extensor carpi radialis brevis. Experimental muscle pain in trapezius led to a decrease in the muscular activity of the wrist extensor (P < 0.02) and decreased the relative rest time in the wrist flexor even in presence of DOMS (P < 0.01). The present result suggests that shoulder pain plays a role in the coordination of wrist flexors and extensors during computer work. © 2010 Elsevier Ltd and The Ergonomics Society.

Mutations in the selenoprotein N1-encoding gene (SEPN1) and ryanodine receptor 1-encoding gene (RYR1) are responsible for half of the reported cases. Mutations in multiple epidermal growth factor-like domains 10-encoding gene (MEGF10) have been identified only recently in a few patients with antenatal to infantile-onset myopathy, with and without minicore pathology. Methods: We report 2 sisters with adult-onset respiratory insufficiency followed by development of limb weakness. Both had scoliosis, distal joint hyperlaxity, and high-arched feet. Results: A biopsy of the right triceps muscle in 1 sister showed multiple minicore structures. She had electromyographic changes of myopathy with fibrillation potentials and myotonic discharges. Next generation sequencing identified novel compound heterozygous missense variants in MEGF10 c.230G>A (p.Arg77Gln) and c.1833T>G (p.Cys611Trp) in both sisters. Conclusions: MEGF10 mutations can cause myopathy with adult-onset respiratory insufficiency. Copyright © 2016 Wiley Periodicals, Inc.

In spite of limited scientific evidence for an altered motor pattern in the shoulder muscles of patients with SIS, they are frequently referred to physiotherapists in an attempt to optimize coordination and strength of the affected muscles. The aim of this study was to compare scapular muscle activity in a general population of subjects with and without SIS during an arm elevation task executed at different speeds in two load conditions. The study is that of a comparative observational using a simple convenience sampling method, comprising 8 females (31.63 +/- 9.39) with SIS and 10 females (29.10 +/- 6.57) without SIS, matched in terms of age, body mass index (BMI) and levels of physical activity. The surface EMG (SEMG) of all the trapezius muscles, i.e., -upper fibers (UT), middle fibers (MT), and lower fibers (LT) serratus anterior (SA), and middle deltoid were recorded during shoulder elevation in a scapular plane at three speeds (slow, moderate, and fast) and two load conditions (with and without load). Data were analyzed using independent t-tests and three-factor repeated measures analysis of variance and Bonferroni method for paired comparisons. The EMG tests results in muscle activities revealed no significant differences between the two groups at three speeds, and with and without load. The findings do not support the claim that SIS necessarily accompanies changes in scapula thoracic and glenohumeral muscle activity.

Although heightened PFM tone has been suggested, the relative contribution of active and passive components of tone remains misunderstood. Likewise, alterations in PFM contractility have been scarcely studied. Aims To compare PFM tone, including the relative contribution of its active and passive components, and muscular contractility in women with PVD and asymptomatic controls. Methods Fifty-six asymptomatic women and 56 women with PVD participated in the study. The PVD diagnosis was confirmed by a gynecologist based on a standardized examination. Outcomes PFM function was evaluated using a dynamometric speculum combined with surface electromyography (EMG). PFM general tone was evaluated in static conditions at different vaginal apertures and during repeated dynamic cyclic stretching. The active contribution of tone was characterized using the ratio between EMG in a static position and during stretching and the proportion of women presenting PFM activation during stretching. Contribution of the passive component was evaluated using resting forces, stiffness, and hysteresis in women sustaining a negligible EMG signal during stretching. PFM contractility, such as strength, speed of contraction, coordination, and endurance, also was assessed during voluntary isometric efforts. Results Greater PFM resting forces and stiffness were found in women with PVD compared with controls, indicating an increased general tone. An increased active component also was found in women with PVD because they presented a superior EMG ratio, and a larger proportion of them presented PFM activation during stretching. Higher passive properties also were found in women with PVD. Women with PVD also showed decreased strength, speed of contraction, coordination, and endurance compared with controls. Clinical Implications Findings provide further evidence of the contribution of PFM alterations in the etiology of PVD. These alterations should be assessed to provide patient-centered targeted treatment options. Strengths and Limitations The use of a validated tool investigating PFM alterations constitutes a strength of this study. However, the study design does not allow the determination of the sequence of events in which these muscle alterations occurred-before or after the onset of PVD. Conclusion Findings support the involvement of active and passive components of PFM tone and an altered PFM contractility in women with PVD. Morin M, Binik YM, Bourbonnais D, et al.

To date, there is little guidance on these patients' therapeutic management, especially those for which neuralgic amyotrophy is triggered by hepatitis E virus (HEV-NA). The study aims to identify specific features that characterize patients bearing the neuralgic amyotrophy triggered by HEV. We first describe a new case report of HEV-neuralgic amyotrophy, with delayed diaphragmatic reach. Then, the literature was searched for reports of HEV-NA (n = 39), and neuralgic amyotrophy with phrenic paresis (n = 42) from 1999 to June 2016. Relevant data were retrieved, analyzed and compared with the parameters of idiopathic neuralgic amyotrophy (n = 199) of the largest cohort, described by Van Alfen and Van Engelen in 2006. Compared to the published cohort, HEV-NA patients were more likely to be men (M/F 34/5 vs. 136/63, p = 0.017), with more frequent bilateral symptoms (86.8% cases vs. 28.5%, p < 0.0001) as well as phrenic paresis (18.0 vs. 6.6%, p = 0.028). The clinical improvement is poor, with 15.6% of cases with remission only. A particular phenotype characteristic of the HEV-induced neuralgic amyotrophy has arisen. Our findings call for action in validating the above-mentioned features that illustrate the HEV-NA cases as an early diagnosis would prevent complications, especially the phrenic damage often associated with a worse functional outcome.

The magnitude of mechanical loading on spine is strongly associated with the occurrence of LBP. Previously, to assess spinal loading, biologically assisted biomechanical models were developed to estimate trunk muscle contraction forces. Loadings on lumbar passive tissues are estimated using anatomical models. However, despite the substantial individual variability in lumbar ligament geometry and viscoelastic properties, the existing anatomical models do not account for these differences. As such, the accuracy of model prediction is compromised especially when mid to full range of trunk motions are involved. This paper describes a new modeling approach to assess lumbar passive tissue loading with the consideration of individual differences in lumbar passive tissue properties. A data set that has trunk bending data from 13 human participants was analyzed; on average, lumbar passive tissue contributes to ~89% of the total spinal compression force at fully flexed trunk postures; the estimated spinal tissue loadings were in feasible ranges as reported from previous cadaver studies; the estimated spinal loadings were also mostly in agreement with results from previous in vivo studies.

Case report and review of literature. Objective. To report the case of a 67-year-old woman who developed delayed onset (6 months) of symptomatic shingles after cervical nerve root decompression in a previously symptomatic dermatome. Methods. The patient's clinic course and outcomes were retrospectively reviewed. The study required no outside funding. The study authors have no financial interest in any of the products or techniques discussed. Results. The patient received definitive treatment for shingles once the zoster form rash manifested. The patient, however, developed postherpetic neuralgia and remained symptomatic at her 2-year postoperative visit. Conclusions. Although shingles is a common disease state affecting patients in the fifth and sixth decades of life, it is rarely seen in the setting of cervical nerve root decompression. This case demonstrates the need to include shingles on the differential diagnosis of recurrent neurogenic pain after anterior cervical decompression and fusion.

Aim of the study was the assessment of possible hypnotizability-related differences in blink reflex (BR) which has a nociceptive component, is sensitive to attentional-emotional traits and states and is modulated by the brain dopamine content. In 10 high (highs) and 10 low hypnotizable participants (lows) BR was induced by electrical nociceptive stimulation of the right supraorbital nerve in the absence (noW) and in the presence of a visual cue preceding the electrical stimulation by 0.1 ms (W01) and by 1 ms (W1). The studied variables were: the amplitude of BR components (R1, R2, R3), the amplitude of the quick change (TO) of heart rate ("turbulence") induced by stimulation and its recovery slope (TS), the role of the Behavioral Inhibition/Activation System (BIS/BAS) in the variability BR and cardiac turbulence. Repeated measures ANOVA did not show any significant difference between highs and lows in blink reflex. TO indicated stimulation related HR increase in highs and decrease in lows, TS was larger in highs. BIS and BAS accounted for the warning effects on the BR amplitude and modulated the hypnotizability and warning effects on TO and TS. Findings do not support dopamine based hypnotizability-related attentional abilities. In contrast, they indicate that hypnotizability modulates the short-lasting cardiac response to electrical nociceptive stimulation. Copyright © 2016 Elsevier Inc.

Many individuals with such knee injuries and pathologies exhibit significant alterations in quadriceps muscle activation that can manifest as a reduction in knee flexion moment (KFM) [1,2] during gait. It is possible that a long term impairment in muscle activity can influence onset and subsequent symptoms of knee OA [3,4]. Interventions attempting to restore muscle function, such as physical therapy or electrical stimulation, have met with limited success, and there remains a need for alternative novel approaches to restore the muscle function of the quadriceps during walking. The properties of the somatosensory system offer a novel opportunity for restoring loss of muscle function associated with conditions such as knee OA or ACL injury. Specifically, the cross modal plasticity of the somatosensory system controls touch response, pain response and proprioception and responds to mechanical stimuli in a manner that over stimulating one mode of the system can gate the response of other modes [5] (Figure 1). Thus, the response of the somatosensory to mechanical cutaneous stimulus has the potential to overcome some of the barriers to restoring muscle function during gait. To test this theory, an active brace was developed to apply intermittent cutaneous stimulation to the thigh and shank through vibration with the goal of activating mechanoreceptors in the leg during walking. Thus, the goal of this study was to test the hypothesis that quadriceps function (as measured by the KFM) in patients with reduced quadriceps function can be modified during gait by applying intermittent vibration to the thigh and shank during the stance phase of the gait cycle. METHODS: The device was tested on a pilot sample of 6 subjects including 2 females and 4 males (age: 42.8 +/- 17.9 yrs, height: 173.9 +/- 10.6 cm, mass: 79.6 +/- 13.18 kg) who had recent knee pain and ACL and/or meniscus injuries and/or surgeries, putting them at risk for reduced quadriceps function. Institutional Review Board approval and signed informed consent were obtained for all subjects prior to study initiation. The intervention consisted of 2 elastic substrates with strategically placed stimulus modules (Figure 2). The straps were applied tightly to avoid slipping around the lower part of the thigh and the upper-shank. The stimulus modules applied direct vibration to the surface of the skin and were equipped with accelerometers to monitor the gait cycle, ensuring that the intermittent stimulus was properly applied from heel strike to midstance. To determine the effects of the intervention, external joint reaction forces and moments were measured by gathering motion and force plate data from the subjects during their gait trials. A three-dimensional optoelectronic system gathered the motion data, while a multi component force plate was used to measure the ground reaction force. The Point Cluster Technique (PCT) was used to calculate joint angles and moments [6]. Five trials in each of the three conditions were performed at a self-selected normal walking speed: control with no brace, intervention with the activated brace, and intervention with the non-activated brace. For each condition, average peak knee flexion moments (KFM), knee adduction moment (KAM), and walking speed were calculated. Student's paired t-test statistics were used to determine significance of outcome parameters with and without the intervention (activated and non-activated). RESULTS: The activated full brace intervention significantly increased the magnitude of the peak KFM (balanced by a net quadriceps moment) during walking by 6 percent over the KFM in the control condition (p=0.008) (Figure 3) as opposed to the non-activated full brace which showed no significant change in KFM. Subjects with the smallest KFM in the control condition responded with a greater KFM increase in the full brace condition (R2=0.674, p=0.044). Additionally, there was no increase in the KAM. DISCUSSION: Our results demonstrate that intermittent vibration significantly increased the peak KFM, with the greatest increase found in subjects with the smallest KFM. The subjects with the smallest peak KFM, indicating a quadriceps avoidance gait possibly due to a muscle deficiency, are the individuals most at need for an intervention to improve muscle activation since the peak external KFM is balanced by a net quadriceps moment. The finding that KFM can increase with intermittent cutaneous stimulation applied to the thigh and shank during gait could have important implications for the rehabilitation of ligament and meniscus-injured knees. By allowing increased quadriceps activation during gait, the newly created device has the potential to addresses problems of quadriceps atrophy following injury and to assist medical professionals in treating these patients. Primary applications for this invention could include rehabilitation for altered muscle activity due to injury or disease, as in individuals with knee osteoarthritis, ligamentous injuries (e.g. ACL injury), degenerative joint conditions or surgical procedures such as meniscectomy or ACL reconstruction. The adaptability of this intervention, in terms of placement of the device on the lower extremities and timing of the active stimulus module component of the device, could make this an efficient tool that could be customized to a patient's specific needs and body type. The preliminary results of this pilot study are promising but will need to be replicated in a larger sample size to demonstrate clinical utility. (Figure Presented).

The aim of this study was to investigate the predictors of function rasing from chair and walking in pregnant women with pelvic girdle pain. Methods: 135 women with pelvic girdle pain were included in the study. Visual analog scale was used to evaluate pain, Pelvic Girdle Qustionnaire for condition-spesific health-related quality of life (symptom-function), Nottingham Health Profile (NHP) for health-related quality of life, Tampa Scale for Kinesiphobia for fear of movement and timed-up and go (TUG) test for function were used. A multiple lineer regression model was used to identify independent predictors of function. Results: A total of 135 pregnant with a mean age of the 30.0+/-4.77 years participated in the study. The significant correlations were found between function and PGQ (r=0.587), NHP (r=0.521) kinesiophobia (r=0.338), pain intensity (r=0.558), gestational week (r=0.264). In multiple linear regression analysis, the three factors significantly associated with function in pregnant with PGP: PGQ, kinesiophobia and pain explained 44% of the variance in function as measured by TUG. Discussion: Rising from chair to walking requires coordination of muscle activity. This function is important for pregnant women because of unstable posture during pregnancy. Our study showed that PGQ, kinesiophobia and pain severity explained 44% of the variance in function in pregnant women due to PGP, although we found significant relations between function and PGQ, NHP, kinesiophobia, pain intensity, gestational week. PGQ was the major; kinesiophobia and pain were the minor contributing factor on the function.

This study compared the coordination between forearm muscles during gripping in individuals with LE and pain-free controls. Intramuscular electrodes recorded myoelectric activity from extensor carpi radialis brevis/longus (ECRB/ECRL), extensor digitorum communis (EDC), flexor digitorum superficialis/profundus (FDS/FDP), and flexor carpi radialis (FCR), bilaterally, in 15 participants with unilateral LE and 15 pain-free controls. Participants performed a gripping task at 20% maximum force in four arm positions. The contribution of each muscle was expressed as a proportion of the summed electromyography of all muscles. In individuals with LE, ECRB contributed less to total electromyography in the symptomatic arm but not the asymptomatic arm than pain-free controls. The contribution of EDC and FDP to total electromyography was greater in both the symptomatic and asymptomatic arm of the LE group, than pain-free controls. No other differences were observed between groups. Subtle differences in muscle activation were present with differing arm positions. These findings indicate forearm muscle activity is modified in LE. It is unknown whether this is cause or effect. Changes in the asymptomatic side may imply involvement of central mechanisms.

Many studies have focused on decreasing PLP with mirror therapy, yet few have examined the same visual ameliorating effect with a virtual or prosthetic limb. Our study addresses the following key questions: (1) does PLP decrease through observation of a 3D limb in a virtual integration environment (VIE) and (2) can consistent surface electromyography (sEMG) signals from the VIE drive an advanced modular prosthetic limb (MPL)? Recorded signals from the residual limb were correlated to the desired motion of the phantom limb, and changes in PLP were scored during each VIE session. Preliminary results show an overall reduction in PLP and a trend toward improvement in signal-to-motion accuracy over time. These signals allowed MPL users to perform a wide range of hand motions.

Methods Twenty adults suffering from chronic neck-shoulder pain and 20 healthy controls were recruited. The SEMG signals from the left and right proximal cervical erector spinae, upper trapezius, lower trapezius and distal extensor carpi radialis, extensor digitorum, flexor digitorum superficialis and, abductor pollicis brevis were recorded during three functional tasks: unilateral and bilateral texting on a smart-phone and computer typing. Normalized mutual information (NMI) values were computed between homonymous proximal and distal muscle pairs as an index of the functional connectivity between muscles pairs. Results NMI among homonymous muscles pairs as well as among proximal and distal muscles pairs were lower among cases compared with controls. Moreover, NMI values in homonymous proximal muscles were higher during texting compared with computer typing with both hands. Conclusions Our results show for the first time that chronic neck-shoulder pain affects the functional connectivity of muscle pairs. Significance The study furnishes novel information about the effects of chronic neck-shoulder pain on the interplay of muscle pairs during functional tasks.

Background: nTMS is a method for focal noninvasive cortical stimulation where small intracranial electrical currents are generated by a powerful extracranial fluctuating magnetic field. Resting motor threshold (rMT) is the minimal intensity required to activate a predetermined muscle group, and serves as a measure of motor cortex excitability. We obtain bilateral rMT for the abductor pollicis brevis muscle for patients with intractable focal epilepsy undergoing nTMS for functional mapping. Thus, we have the opportunity to test whether the rMT changes as a function of age or lateralization relative to the seizure focus. Design/Methods: Bilateral rMT obtained with a figure-of-eight coil, guided by the patient's own MRI using frameless stereotaxy. Motor mapping was performed at 110% rMT, or 100% machine output (MO) when MT was >100% MO. Heart rate (HR) and HR variability are known to vary with levels of pain and stress and were monitored during stimulation using electrocardiogram (ECG) artifact in the left deltoid electromyogram (EMG) channel. Results: 117 patients (108 <18y.o.) with intractable epilepsy underwent nTMS for functional mapping. There were no atypical seizures, status epilepticus or epilepsy exacerbation. Typical seizures occurred in 4 patients during stimulation. Importantly, there was no significant change in HR or HR variability during the nTMS sessions, supporting the tolerability of the procedure. Younger children had higher rMT (lower excitability) relative to adolescents and young adults. There was no significant difference in rMT between the hemispheres, including cases of focal epilepsy. Conclusions: nTMS is a safe and tolerable procedure in patients with intractable epilepsy. Furthermore, rMT does not differ significantly between the epileptic and non-epileptic hemispheres, even in the presence of antiepileptic medication.

Shoulder pain is among the symptoms associated with TMD. The purpose of this study was to investigate the association between TMD and rotator cuff disease (RCD) and related genetic aspects. All subjects underwent orofacial and shoulder examinations. The control group comprised 30 subjects with no pain. Affected subjects were divided into three groups: RCD (TMD-free, n = 16), TMD (RCD-free, n = 13), and TMD/RCD (patients with both RCD and TMD, n = 49). A total of eight single nucleotide polymorphisms in the ESRRB gene were investigated. A chemiluminescent immunoassay was used to measure estradiol levels. Surface electromyography recorded head and cervical muscle activity. The chi2 test and Student t-test/Mann-Whitney test were used to assess the significance of nominal and continuous variables. A P-value of <0.05 was considered significant. TMD subjects were seven times more susceptible to RCD than controls. The rs1676303 TT (P = 0.02) and rs6574293 GG (P = 0.04) genotypes were associated with RCD and TMD, respectively. TMD/RCD subjects showed associations with rs4903399 (P = 0.02), rs10132091 (P = 0.02), and CTTCTTAG/CCTCTCAG (P = 0.01) haplotypes and lower muscle activity. Estradiol levels were similar among groups. This study supports TMD as a risk factor for RCD. ESRRB haplotypes and low muscle activity are common biomechanical characteristics in subjects with both diseases. Copyright © 2015 International Association of Oral and Maxillofacial Surgeons.

The aim of this study was to compare segmental muscle activation and variability of the GMed, GMin and tensor fascia latae (TFL) during gait in post-menopausal women with and without GTPS. Intramuscular electrodes were inserted into segments of GMin (x2) and GMed (x3) and a surface electrode placed on TFL. Ten control participants and 8 with GTPS completed six walking trials. Peak amplitude, average amplitude and time to peak from each phase of the gait cycle (0-30%, 30%- toe off (TO), total stance and swing) were compared between groups using independent t-tests and effect-size (ES) calculations. Variability of muscle activation was calculated using the mean coefficient of variation (CV). Reversal of anterior GMin electromyographic burst pattern and greater average muscle activity was found in the GTPS group compared to controls: 0-TO for anterior GMin (p < 0.05), anterior and middle GMed (p < 0.01); 0-30% for posterior GMin (p < 0.01) and GMed (p < 0.05). No significant differences were identified in TFL. Overall, this study found increased segmental gluteal muscle activation, decreased hip abduction strength, and reduced variability in muscle activation in post-menopausal women with GTPS, compared with controls.

The present study investigates biopsychosocial differences, with specific focus on rate of force development (RFD) and work ability, between workers with and without chronic upper limb pain. Methods: Eighty-two male slaughterhouse workers, 49 with chronic upper limb pain and 33 pain-free controls participated in the study. Maximal muscle strength, RFD, and muscle activity was determined from fast and forceful maximal voluntary contractions for the shoulder and hand. Participants filled out a questionnaire on work ability (work ability index), work disability (Work module of DASH questionnaire), fear avoidance, and self-rated health. Additionally, pressure pain threshold (PPT) was measured in muscles of the arm, shoulder and lower leg. Results: Muscle strength and RFD (determined within time intervals of 30, 50, 100, and 200 ms relative to onset of contraction) was 28 % and 58-78 % lower, respectively, in workers with chronic pain compared with pain-free controls, and paralleled by reduced muscle activity (all p < 0.001). Workers with chronic pain had lower PPT of the arm, shoulder and lower leg (p < 0.01), and reported impaired work ability index score and general health along with higher work disability and fear avoidance compared with controls (all p < 0.0001). No differences were observed between the groups in regard to age, BMI, physical activity level, job position and duration of slaughterhouse work (all p > 0.4). Conclusions: Chronic upper limb pain was paralleled by reduced neuromuscular function of the shoulder and hand along with impaired work ability, work disability and general health. Future studies on chronic pain management at the workplace should carefully consider the biopsychosocial nature of pain when designing and implementing preventive strategies.

Twenty-five female FM patients and 25 age- and sex-matched healthy controls (HCs) performed three precision motor tasks: (1) maintain a steady shoulder abduction angle of 45degree while receiving visual feedback about upper arm position and supporting external loads (0.5, 1, or 2 kg), (2) maintain the same shoulder abduction angle without visual feedback (eyes closed) and no external loading, and (3) a joint position sense test (i.e., assessment of proprioceptive accuracy). Patients had more extensive increase in movement variance than HCs when visual feedback was removed (P < 0.03). Proprioceptive accuracy was related to movement variance in HCs (R >= 0.59, P <= 0.002), but not in patients (R <= 0.25, P >= 0.24). There was no difference between patients and HCs in coherence between sEMG and acceleration data. These results may indicate that FM patients are more dependent on visual feedback and less reliant on proprioceptive information for upper limb posture control compared to HCs.

As advanced genetic testing is performed, molecular diagnosis can be obtained. Identifying new gene mutations can lead to further understanding of disease. Methods and Results: We report a single case of a patient with earlyonset amyotrophic lateral sclerosis, evaluated at University of Texas Health Houston Science Center from 2011-2014. Initial genetic testing did not reveal an etiology in this patient. Through wholeexome sequencing, a VRK1 mutation was identified. Conclusions and Relevance: We identify a possible new cause of hereditary amyotrophic lateral sclerosis, VRK1 mutation. This case report also expands the phenotypic spectrum of this mutation in neurologic diseases. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.

Verbal scales, visual analog scales (VAS) or numeric rating scales (NRS) count among the most common tools, which are restricted to patients with normal mental abilities. There also exist instruments for pain assessment in people with verbal and/or cognitive impairments and instruments for pain assessment in people who are sedated and automated ventilated. However, all these diagnostic methods either have limited reliability and validity or are very time-consuming. In contrast, biopotentials can be automatically analyzed with machine learning algorithms to provide a surrogate measure of pain intensity. Methods In this context, we created a database of biopotentials to advance an automated pain recognition system, determine its theoretical testing quality, and optimize its performance. Eightyfive participants were subjected to painful heat stimuli (baseline, pain threshold, two intermediate thresholds, and pain tolerance threshold) under controlled conditions and the signals of electromyography, skin conductance level, and electrocardiography were collected. A total of 159 features were extracted from the mathematical groupings of amplitude, frequency, stationarity, entropy, linearity, variability, and similarity. Results We achieved classification rates of 90.94% for baseline vs. pain tolerance threshold and 79.29% for baseline vs. pain threshold. The most selected pain features stemmed from the amplitude and similarity group and were derived from facial electromyography. Conclusion The machine learning measurement of pain in patients could provide valuable information for a clinical team and thus support the treatment assessment.

In this study we evaluate whether an acute noxious stimulus induces a change in the way motor modules are combined to generate movement by neck muscles. The neck region was selected as it is a region with potentially high muscular redundancy. We used the motor modules framework to assess the redistribution of muscular activity of 12 muscles (6 per side) in the neck region of 8 healthy individuals engaged in a head and neck aiming task, in non-painful conditions (baseline, isotonic saline injection, post pain) and after the injection of hypertonic saline into the right splenius capitis muscle. The kinematics of the task was similar in the painful and control conditions. A general decrease of activity was noted for the injected muscle during the painful condition together with an increase or decrease of the activity of the other muscles. Subjects did not adopt shared control strategies (motor modules inter subject similarity at baseline 0.73+/-0.14); the motor modules recorded during the painful condition could not be used to reconstruct the activation patterns of the control conditions, and the painful stimulus triggered a subject-specific redistribution of muscular activation (i.e., in some subjects the activity of a given muscle increased, whereas in other subjects it decreased with pain). Alterations of afferent input (i.e., painful stimulus) influenced motor control at a multi muscular level, but not kinematic output. These findings provide new insights into the motor adaptation to pain. Copyright © 2015 Gizzi et al.

This study investigated trunk muscle timing in a subgroup of patients with NSLBP attributed to movement coordination impairment (MCI) and matched asymptomatic controls in response to a rapid arm-raising task. Twenty-one NSLBP subjects and 21 matched controls had arm motion and surface EMG data collected from seven bilateral trunk muscles. Muscle onset and offset relative to deltoid muscle activation and arm motion, duration of muscle burst and abdominal-extensor co-contraction time were derived. Trunk muscle onset and offset latencies, and burst and co-contraction durations were not different (p >.05) between groups. Patterns of trunk muscle activation and deactivation relative to arm motion were not different. Task performance was similar between groups. Trunk muscle timing does not appear to be an underlying impairment in the subgroup of NSLBP with MCI. Copyright © 2017 Human Kinetics, Inc.

Coordination of the transverse abdominis (TrA), a deep postural muscle, has been shown to be reduced in persons with low back pain. No previous research has studied the effect of age on the activation on this muscle. Objective: To assess the effect of age on TrA activation in response to rapid arm abduction. Design: Cross-sectional cohort study. Setting: University exercise physiology laboratory. Participants: A total of 18 adult men (aged 27 +/- 7.0 years) for the younger group and 11 older adults (5 men and 6 women, aged 59.6 +/- 4.0 years) were recruited for this study. Method: Participants were positioned on a treatment table and performed a series of rapid arm abduction movements with their right arm while the activation of the TrA muscle was recorded using ultrasound imaging. Onset of arm abduction was measured using surface electromyography and synchronized with the ultrasound through the ultrasound unit's electrocardiogram channel. The mean time difference between the 2 events was calculated during post-hoc analysis. Main Outcome Measurements: A Mann-Whitney test was performed to test for differences in the onset performance of the TrA muscle between the 2 groups. Results: Results showed that the older group was significantly slower than the younger group in engaging their TrA in response to the rapid arm abduction (P = .036). A separate analysis of the older group data showed that no significant differences existed between the male and female participants that could potentially have acted as a confounding factor for the main finding (P = .126). Conclusions: This study shows that older adults were slower than younger adults in activating their TrA muscle in response to rapid arm abduction. This delay has the potential to lead to increased occasions when the low back is unprotected, increasing the likelihood of injury or low back pain.

In this study, we aimed to investigate the effect of experimental muscle pain on the neural control of muscle force at higher frequency bands, associated with afferent feedback (alpha band, 5-13 Hz) and with descending cortical input (beta band, 15-30 Hz). Single-motor unit activity was recorded, in two separate experimental sessions, from the abductor digiti minimi (ADM) and tibialis anterior (TA) muscles with intramuscular wire electrodes, during isometric abductions of the fifth finger at 10% of maximal force [maximum voluntary contraction (MVC)] and ankle dorsiflexions at 25% MVC. The contractions were repeated under three conditions: no pain (baseline) and after intramuscular injection of isotonic (0.9%, control) and hypertonic (5.8%, painful) saline. The results showed an increase of the relative power of both the force signal and the neural drive at the tremor frequency band (alpha, 5-13 Hz) between the baseline and hypertonic (painful) conditions for both muscles (P < 0.05) but no effect on the beta band. Additionally, the strength of motor unit coherence was lower (P < 0.05) in the hypertonic condition in the alpha band for both muscles and in the beta band for the ADM. These results indicate that experimental muscle pain increases the amplitude of the tremor oscillations because of an increased variability of the neural control (common synaptic input) in the tremor band. Moreover, the concomitant decrease in coherence suggests an increase in independent input in the tremor band due to pain. Copyright © 2015 the American Physiological Society.

However, no study has compared the relative effectiveness of gait parameters for assessing motor performance in low back disorders after surgery. The purpose of the current review was to determine the sensitive gait parameters that address physical improvements in each specific spinal disorder after surgical intervention. Methods Articles were searched with the following inclusion criteria: 1) population studied consisted of individuals with low back disorders requiring surgery; 2) low back disorder was measured objectively using gait assessment tests pre- and post-surgery. The quality of the selected studies was assessed using Delphi consensus, and meta-analysis was performed to compare pre- and post-surgical changes. Findings Thirteen articles met inclusion criteria, which, almost exclusively, addressed two types of spinal disorders/interventions: 1) scoliosis/spinal fusion; and 2) stenosis/decompression. For patients with scoliosis, improvements in hip and shoulder motion (effect size = 0.32-1.58), energy expenditure (effect size = 0.59-1.18), and activity symmetry of upper-body muscles during gait were present after spinal fusion. For patients with spinal stenosis, increases in gait speed, stride length, cadence, symmetry, walking smoothness, and walking endurance (effect size = 0.60-2.50), and decrease in gait variability (effect size = 1.45) were observed after decompression surgery. Interpretation For patients with scoliosis, gait improvements can be better assessed by measuring upper-body motion and EMG rather than the lower extremities. For patients with spinal stenosis, motor performance improvements can be captured by measuring walking spatio-temporal parameters, gait patterns, and walking endurance. Copyright © 2015 Elsevier Ltd.

Characterizing relative scapular muscle activity deficits in participants with shoulder pain will provide foundational knowledge to develop rehabilitation programs. Methods Participants were recruited with subacromial pain syndrome and an asymptomatic control group matched for age, gender, and dominant arm (N=56). Surface electromyographic muscle activity was recorded from the upper, middle, and lower trapezius (UT, MT, LT) and serratus anterior (SA) during 5 repetitions of a weighted arm elevation task. Muscle activity was normalized to a reference contraction and then expressed as UT/MT, UT/LT, UT/SA, and LT/SA ratios. Ratios were compared between groups and across 3 arm angle intervals during ascending and descending elevation. Results A 2x3 mixed-model analysis of variance yielded a group main effect for the UT/LT ratio, with a higher ratio in the subacromial pain group during ascending (mean difference,0.92; P=.008) and descending (mean difference,0.70; P=.030). For the LT/SA ratio, there was a group effect: a lower ratio in the subacromial group during ascending (mean difference,-0.25; P=.026) and descending (mean difference,-0.51; P=.032). There were no differences for the UT/MT or UT/SA. Discussion There is a disruption in coordination between the LT and SA and the UT and LT during an arm elevation task in patients with subacromial pain syndrome. The LT was part of both altered ratios, indicating the relative importance of the LT. Future research should determine if exercises aimed at restoring the dysfunctional LT/SA and UT/LT force couples are beneficial to reduce shoulder pain and disability in patients with unilateral shoulder pain.

The Functional Re-adaptive Exercise Device (FRED) has been developed to activate the deep spinal muscles, lumbar multifidus (LM) and transversus abdominis (TrA), that provide inter-segmental control and spinal protection. The FRED provides an unstable base of support and combines weight bearing in up-right posture with side alternating, elliptical leg movements, without any resistance to movement. The present study investigated the activation of LM, TrA, obliquus externus (OE), obliquus internus (OI), abdominis, and erector spinae (ES) during FRED exercise using intramuscular fine-wire and surface EMG. Nine healthy male volunteers (27 +/- 5 years) have been recruited for the study. FRED exercise was compared with treadmill walking. It was confirmed that LM and TrA were continually active during FRED exercise. Compared with walking, FRED exercise resulted in similar mean activation of LM and TrA, less activation of OE, OI, ES, and greater variability of lumbo-pelvic muscle activation patterns between individual FRED/gait cycles. These data suggest that FRED continuously engages LM and TrA, and therefore, has the potential as a stationary exercise device to train these muscles. Copyright © 2017 The Authors.

Trying to understand its causes has been used time analysis of electromyography (EMG), but this method shows controversies. The aim of this study was to apply a method of processing the EMG signal in the frequency domain of the vastus lateralis (VL) and vastus medialis (VM) muscles for the characterization of PFPS. Methods Were evaluated 33 women divided into two groups: I) PFPS group: n = 11, diagnosis of PFPS, average age: 24 +/- 3 years, weight: 57.3 +/- 5.3 kg and height: 161.9 +/- 5,9cm ii) control group: n = 22, with no symptoms of PFPS, average age: 23 +/- 2 years, weight: 55.0 +/- 6.0 kg and height: 161.2 +/- 4.8 cm. The project was approved by the Local Ethics Comitee and the volunteers signed a consent form. EMG signals were obtained using a conditioner module (Lynx, Sao Paulo, SP, BRA; model EMG 1000-8-4I) that used a butterworth type band-pass digital filter with cutoff frequencies between 20 and 500 Hz and acquisition frequency of 4000 Hz. Two pairs of Ag/AgCl electrodes were positioned at VM and VL. Data collecting was done during the ascent of 3 steps, alternating the members, with selfselected speed; each volunteer executed 12 tries. EMG data was processed using MatLab to obtain the median frequency (Fmed) and frequency in bands of low, medium and high frequencies: 15-45, 45-96 and 96-400Hz respectvely. For statistical analysis, were used ANOVA one-way, with Tukey pos-hoc, with p<0.05 significant. Results In tables 1 to 3, are shown the results of Fmed, and the intensity divided into frequency bands. Discussion The FMed is related to muscle fiber type, being the type II fibers more potent, showing higher FMed [Kupa, 1995; Pizzato, 2007]. Thus the high levels of FMed for the VL compared to the VM can be explained by the predominance of type II fibers, making it stronger and thus causing a lateral displacement of the patella. In the division of the frequency bands it was observed that the PFPS group showed a significant difference in the bands of low and medium frequency when compared to the control group. Thus, it can be inferred that this data behavior is characteristic of the PFPS group. Therefore, exploration of the electromyographic signal in the frequency domain might allow the characterization of PFPS. (Table Presented).

Moreover, the stair climbing is usually used as therapeutic resource. However, few studies have been conducted to characterize the movement during the ascent or descent of stairs and these studies concluded that the high variability of the data could not confirm the results [Yu, 1997] . In this way, this study aimed to verify which parameters show less variation and so, are more appropriate to characterize the stair climbing. Methods It were evaluated 12 pain-free female volunteers with 24.08 +/- 2.90 years, 1.63 +/- 0.04m in height and weight of 60.27 +/- 7.64kg. for the evaluation were used two pairs of surface electrodes Ag/AgCl, a signal conditioner for data collection of EMG (EMG 1000-8 BIO-4l, LYNX, Brazil) and a force plate (Bertec, Brazil), that was insert in the fourth degree of a seven degree stair, in a way that it was not visible to the volunteers. The electrodes were positioned at the vastus medialis (VM) and lateralis (VL) of the quadriceps and the volunteers executed a little walking before starts the stair climbing, that began with the left foot and occurred in a continuous way, with alternating of the members, in a self-selected speed; and, in the end of the stair, a little walking again. Each volunteer repeated the movement 10 times. The analyzed parameters were: Onset in automatic manner [Cowan, 2002], visual onset, onset by cross correlation, time of start-peak activation, activation duration, median time of the activation (Tmed), intensity of the activation (RMS), muscular coactivation, median frequency (Fmed) and porcentage of torque variation (PTV). To verify which of the analyzed parameters showed the lesser variations, were calculated the standard error of the mean (SEM) and the coefficient of variation (CV). Results In the table 1 are showed SEM and CV of the analyzed parameters. Discussion Considering that in this study was evaluated a group of clinically healthy individuals with similar anthropometric characteristics, it was expected to get a low variation in the data. Regarding EMG data analyzed in the time domain, it is observed that there is a low variability, especially the onset obtained by cross-correlation. For the Fmed data, we found a higher SEM. Also, it was shown that the PTV has a low variation. Thus, we conclude that the onset must be analyzed by crosscorrelation, confirming data from previous study [Kuriki, 2011], and the PTV should be used to compare pathological groups to pain-free individuals group, as these parameters showed low variation. Regarding the analysis in the frequency domain, it is concluded that the Fmed is not an appropriate parameter for comparisons between groups, since within the control group shows high variation; so, in the frequency domain, the signal must undergo further processing to see if it can be used as a division of the signal in frequency bands.

This study investigated the effects of bilateral experimental neck pain on trunk and axioscapular muscle function and pain sensitivity. Methods: In 25 healthy volunteers, bilateral experimental neck pain was induced in the splenius capitis muscles by hypertonic saline injections. Isotonic saline was used as control. In sitting, subjects performed slow, fast and slow-resisted unilateral arm movements before, during and after injections. Electromyography (EMG) was recorded from eight shoulder and trunk muscles bilaterally. Pressure pain thresholds (PPTs) were assessed bilaterally at the neck, head and arm. Data were normalized to the before-measures. Results: Compared with control and post measurements, experimental neck pain caused (1) decreased EMG activity of the ipsilateral upper trapezius muscles during all but slow-resisted down movements (p < 0.001), and (2) increased EMG activity in the ipsilateral erector spinae muscle during slow and fast movements (p < 0.02), and in the contralateral erector spinae muscle during all but fast up and slow-resisted down movements (p < 0.007). The PPTs in the painful condition increased at the head and arm compared with post measurements and the control condition (p < 0.001). In the post-pain condition, the neck PPT was decreased compared with the control condition (p < 0.001). Conclusion: Acute bilateral neck pain reorganized axioscapular and trunk muscle activity together with local hyperalgesia and widespread hypoalgesia indicating that acute neck pain immediately affects trunk and axioscapular function which may affect both assessment and treatment. Significance: Bilateral clinical neck pain alters axioscapular muscle coordination but only effects of unilateral experimental neck pain has been investigated. Bilateral experimental neck pain causes task-dependent reorganized axioscapular and trunk muscle activity in addition to widespread decrease in pressure pain sensitivity.

Prospective study was designed comparing results of Constant Shoulder Score (CSS), Shoulder Pain and Disability Index (SPADI) and EMG score of the trapezius muscle (mT) before and after surgery. One side of the neck was monitored during surgery with intraoperative nerve monitor. EMG scores of the mT 6 months postoperatively were statistically better on monitored as compared to the non-monitored side of the neck (p = 0.041), while the differences of the CSS and SPADI were not statistically significant. Patients with better EMG scores of the mT at 6 weeks recuperated better and with smaller decrease of the CSS. Intraoperative monitoring is beneficial at the beginning of the surgeon's learning curve and in the process of familiarizing with anatomical variation of the CN XI.

METHODS: Surface electromyography (sEMG) of masticatory muscles was made in 30 chronic TMD patients, diagnosed with disc displacement with reduction (DDR) and pain. Two 15-patient subgroups, with moderate (TMDmo) and severe (TMDse) signs and symptoms, were compared with a control group of 15 healthy subjects matched by age. The experimental tasks were: a 5s inter-arch maximum voluntary clench (MVC); right and left 15s unilateral gum chewing tests. Standardized sEMG indices characterizing masseter and temporalis muscles activity were calculated, and a comprehensive functional index (FI) was introduced to quantitatively summarize subjects' overall performance. Mastication was also clinically evaluated. RESULTS: During MVC, TMDse patients had a significantly larger asymmetry of temporalis muscles contraction. Both TMD groups showed reduced coordination between masseter and temporalis muscles' maximal contraction, and their muscular activity distribution shifted significantly from masseter to temporalis muscles. During chewing, TMDse patients recruited the balancing side muscles proportionally more than controls, specifically the masseter muscle. When comparing right and left side chewing, the muscles' recruitment pattern resulted less symmetric in TMD patients, especially in TMDse. Overall, the functional index of both TMDmo and TMDse patients was significantly lower than that obtained by controls. CONCLUSIONS: Chronic TMD patients, specifically those with severe symptomatology, showed a reorganized activity, mainly resulting in worse functional performances. Copyright © 2016 Elsevier Ltd.

Increasing thorax rotation relative to pelvic rotation preloads the trunk muscles by accentuating their length and allowing them to use the energy stored in their elastic elements to produce more power. As the thorax and pelvis turn back towards the ball during the downswing, more skilled golfers are known to laterally slide their pelvis toward the target, which further contributes to final clubhead speed. However, despite the apparent performance benefits associated with these sequences, it has been argued that the lumbar spine is incapable of safely accommodating the forces they produce. This notion supports a link between the repeated performance of the golf swing and the development of golf-related low back injuries. Of the complaints reported by golfers, low back injuries continue to be the most prevalent, but the mechanism of these injuries is still poorly understood. This review highlights that there is a paucity of research directly evaluating the apparent link between the modern golf swing and golf-related low back pain. Furthermore, there has been a general lack of consensus within the literature with respect to the methods used to objectively assess the golf swing and the methods used to derived common outcome measures.

The overall objective of our research is to develop simulation models to investigate the effects of posture and muscular strength on spinal segmental loading, and thus the associated risk of injury.5 The aims of the present study were to further investigate alignment- and kinematics-dependent loading patterns, based on literature and laboratory measures of posture and motion data from young and elderly subjects. Materials and Methods Twenty-four young and 22 elderly subjects volunteered to participate. Average group ages were 27.5 years (standard deviation [SD] = 4.0) and 68.3 years (SD = 3.9), respectively. None of the recruited participants had undergone spinal surgery and none suffered from any back condition. Ethical approval and written consent were obtained. Spinal posture was determined with a noninvasive skin-surface device (SpinalMouse, Idiag). The spinal contour was measured twice in four body positions: (1) standing neutral, (2) erect posture, (3) flexed forward position, and (4) hyperextended posture. A musculoskeletal model of the thoracolumbar spine5 was further developed in the AnyBody Modeling System (AnyBody Technology) combining properties of lumbar models previously established by deZee, 2007 and Han, 2011.6,7 The present model adds a fully articulated thoracic region and ribcage to our prior simulation model. Lumbar motion patterns were derived from fluoroscopy measurements8 during a flexion maneuver in two groups of volunteers: healthy and with low back pain. Three motion patterns were distinguished: (1) all intervertebral joints angulate simultaneously during flexion, (2) upper lumbar joints rotate first and are followed by lower joints in a sequential manner, and (3) angulation of lower levels precedes the upper ones. Segmental forces (compression and shear) were calculated for each motion pattern. Results An average spine curvature, found from the static measurements of the neutral upright posture, was characterized by thoracic kyphosis angles of 49.4 degrees (SD = 11.3) and 45.9 degrees (SD = 6.0) for the young and elderly groups, respectively. Lumbar (L1S1) lordosis angles were 27.4 degrees (SD = 10.6) and 20.4 degrees (SD = 13.1), respectively. Simulations of the sequential and simultaneous motion patterns revealed that fewer muscles and lower muscle activities were necessary to perform lumbar flexion than when the same magnitude of flexion was achieved using the generic spinal rhythm (SR) incorporated in the AnyBody base model (constant ratio of segmental motion). Consequently, compression forces were significantly reduced, by up to 1,200N or 55%, compared with the reference model (Fig. 1). Conclusion The degree of thoracic kyphosis for young subjects measured in our study (49.4 degrees) compares favorably with previous radiographic findings (47.5 degrees). The lumbar lordosis angle that we measured (27.4 degrees) is similar to that reported in other studies with skin-surface devices (23-33 degrees); however, these values are considerably lower than those obtained from methods based on medical imaging (44-63 degrees). Therefore, skin-based systems can be used for subject-specific model definition in the thoracic region, but correction is required for the lumbar region. A surprisingly high variability in the spine curvature was observed, even for young volunteers, highlighting the potential limitations of generic simulation models. Elderly subjects tended toward a lower degree of kyphosis and significantly less lordosis. We have seen in previous simulations that flattening of the back can lead to increased segmental forces during flexion. In contrast to our prior results with arbitrarily defined spinal motion patterns, we have shown that physiological alterations in the temporal sequence of segmental motion can have a substantial influence on muscle recruitment and segmental loading. Compensatory measures, for example, for easing pain, may therefore increase-or decrease-the risk of injury. These results imply that the vertebral kinematics have a profound effect on model predictions, strengthening the necessity to measure and implement realistic vertebral kinematics for spinal motion simulations. In the referenced fluoroscopic study (Okawa, 1998), only a small number of participants were measured, and the motion recording was limited to L2-L5 levels. Therefore, the next step in our investigation will be the combination of the musculoskeletal model with subject specific, whole-spine posture, and motion data from the young and elderly subjects.

However, clinical and functional signs and symptoms correlating with SIJ pain are widely unknown. Pelvic belts are routinely applied to treat SIJ pain but without sound evidence of their pain-relieving effects. This case-control study compares clinical and functional data of SIJ patients and healthy control subjects and evaluates belt effects on SIJ pain. Methods 17 SIJ patients and 17 healthy controls were included in this prospective study. The short-form 36 survey and the numerical rating scale were used to characterize health-related quality of life in patients in a six-week follow-up and the pain-reducing effects of pelvic belts. Elec-tromyography data were obtained from the gluteus maximus, biceps femoris, rectus femoris and medial vastus. Alterations of muscle activity, variability and gait patterns were compared in patients and controls along with the belts' effects in a dynamic setting when walking. Results Significant improvements were observed in the short-form 36 survey of the SIJ patients, especially in the physical health subscores. Minor declines were also observed in the numerical rating scale on pain. Belt-related changes of muscle activity and variability were similar in patients and controls with one exception: the rectus femoris activity decreased significantly in patients with belt application when walking. Further belt effects include improved cadence and gait velocity in patients and controls. Conclusions Pelvic belts improve health-related quality of life and are potentially attributed to decreased SIJ-related pain. Belt effects include decreased rectus femoris activity in patients and improved postural steadiness during locomotion. Pelvic belts may therefore be considered as a cost-effective and low-risk treatment of SIJ pain. Copyright © 2015 Hammer et al.

The size and structure of motor variability of shoulder and elbow joint angles were quantified using cycle-to-cycle standard deviations of several kinematics properties, and indices based on sample entropy and recurrence quantification analysis. Decreasing accuracy demands increased both the size and structure of motor variability. However, when simultaneously lowering the accuracy demand and increasing pace, motor variability decreased to values comparable to those found when pace alone was increased without changing accuracy. Thus, motor variability showed some speed-accuracy trade-off, but the pace effect dominated the accuracy effect. Hence, this trade-off was different from that described for end-point performance by Fitts' law. The combined effect of accuracy and pace and the resultant decrease in motor variability are important to consider when designing sustainable work systems comprising repetitive precision tasks. PRACTITIONER SUMMARY: Variability in movements and/or muscle activities between repeats of the same repetitive task is associated with important occupational outcomes, including fatigue, discomfort and pain. This study showed that simultaneously decreasing accuracy and increasing pace in short-cycle repetitive work led to decreased motor variability in arm movements, indicating less favourable ergonomics conditions.

In this study, we investigated the influence of lumbar extensor muscle fatigue on lumbar-pelvic coordination patterns during weightlifting. Each of the 15 male subjects performed five repetitions of weightlifting tasks both before and after a lumbar extensor muscle fatiguing protocol. Lumbar muscle electromyography was collected to assess fatigue. Trunk kinematics was recorded to calculate lumbar-pelvic continuous relative phase (CRP) and CRP variability. Results showed that fatigue significantly reduced the average lumbar-pelvic CRP value (from 0.33 to 0.29 rad) during weightlifting. The average CRP variability reduced from 0.17 to 0.15 rad, yet this change ws statistically not significant. Further analyses also discovered elevated spinal loading during weightlifting after the development of lumbar extensor muscle fatigue. Our results suggest that frequently experienced lumbar extensor muscle fatigue should be avoided in an occupational environment. PRACTITIONER SUMMARY: Lumbar extensor muscle fatigue generates more in-phase lumbar-pelvic coordination patterns and elevated spinal loading during lifting. Such increase in spinal loading may indicate higher risk of back injury. Our results suggest that frequently experienced lumbar muscle fatigue should be avoided to reduce the risk of LBP.

Surface electromyographic (EMG) signals were recorded from multiple locations over the lumbar erector spinae muscle with a 13 x 5 grid of electrodes from 19 people with chronic nonspecific LBP and 17 control subjects as they performed a repetitive lifting task. The EMG root mean square (RMS) was computed for each location of the grid to form a map of the EMG amplitude distribution. Pressure pain thresholds (PPT) were recorded before and after the lifting task over a similar area of the back. For the control subjects, the EMG RMS progressively increased more in the caudal region of the lumbar erector spinae during the repetitive task, resulting in a shift in the distribution of muscle activity. In contrast, the distribution of muscle activity remained unaltered in the LBP group despite an overall increase in EMG amplitude. PPT was lower in the LBP group after completion of the repetitive task compared to baseline (average across all locations: pre: 268.0 +/- 165.9 kPa; post: 242.0 +/- 166.7 kPa), whereas no change in PPT over time was observed for the control group (320.1 +/- 162.1 kPa; post: 322.0 +/- 179.5 kPa). The results demonstrate that LBP alters the normal adaptation of lumbar erector spinae muscle activity to exercise, which occurs in the presence of exercise-induced hyperalgesia. Reduced variability of muscle activity may have important implications for the provocation and recurrence of LBP due to repetitive tasks. © 2014 Published by Elsevier B.V. on behalf of International Association for the Study ofPain.

Our aims were to quantify functional, self-reported and physiological indices of spasticity in individuals with thoracic spinal cord injury (SCI; 3 women, 9 men; 19-52 years), and to compare the strength and direction of associations between these measures. The functional measure we introduced involved recording involuntary electromyographic activity during a transfer from wheelchair to bed which is a daily task necessary for function. High soleus (SL) and tibialis anterior (TA) F-wave/M-wave area ratios were the only physiological measures that distinguished injured participants from the uninjured (6 women, 13 men, 19-67 years). Hyporeflexia (decreased SL H/M ratio) was unexpectedly present in older participants after injury. During transfers, the duration and intensity of involuntary electromyographic activity varied across muscles and participants, but coactivity was common. Wide inter-participant variability was seen for self-reported spasm frequency, severity, pain and interference with function, as well as tone (resistance to imposed joint movement). Our recordings of involuntary electromyographic activity during transfers provided evidence of significant associations between physiological and self-reported measures of spasticity. Reduced low frequency H-reflex depression in SL and high F-wave/M-wave area ratios in TA, physiological indicators of reduced inhibition and greater motoneuron excitability, respectively, were associated with long duration SL and biceps femoris (BF) electromyographic activity during transfers. In turn, participants reported high spasm frequency when transfers involved short duration TA EMG, decreased co-activation between SL and TA, as well as between rectus femoris (RF) vs. BF. Thus, the duration of muscle activity and/or the time of agonist-antagonist muscle coactivity may be used by injured individuals to count spasms. Intense electromyographic activity and high tone related closely (possibly from joint stabilization), while intense electromyographic activity in one muscle of an agonistantagonist pair (especially in TA vs. SL, and RF vs. BF) likely induced joint movement and was associated with severe spasms. These data support the idea that individuals with SCI describe their spasticity by both the duration and intensity of involuntary agonistantagonist muscle coactivity during everyday tasks.

Major weight-bearing joints are affected most. However, possible effects on trunk muscle activity have not been examined so far. The objective of this work was to study consequences of haemarthropathy on characteristics of trunk muscles in PWH while standing on surfaces with different mechanical properties. Methods: Surface EMG of internal oblique (IO) and multifidus (MF) muscles were bilaterally recorded during a natural bilateral stance in 20 PWH with severe haemophilia A [age: 42 years (SD: 10)] and 25 non-haemophilic controls [NHC, 43 (12)]. Amplitude ratios, a symmetry index between sides and the co-activation ratio of IO over MF served as outcome measures and compared standing on three different surfaces (stable, soft, unsteady). Results: PWH revealed markedly restricted lower extremity joints (P < 0.001), but without any hint of back pain. Neither result revealed significant main or interaction effects of 'group' (P > 0.24). Group-independent analyses showed amplitude ratios (MF: P < 0.05) as well as symmetry indices (MF: P < 0.02) significantly altered by 'surface' in NHC only. Effects of utilizing soft vs. unsteady surfaces were not detectable (P > 0.77). Conclusion: Utilizing unstable surfaces does not lead to altered trunk muscle activity in PWH. Differently than expected, a quite similar behaviour of lower trunk muscles in terms of applied indices can be found in PWH and NHC. Ascending alterations of muscle coordination in PWH could not be verified.

This training, however, may not transfer to other known postural impairments, such as automatic postural responses to external perturbations. Objectives: To evaluate the extent current treatments of motor retraining ameliorate impaired postural coordination when responding to a perturbation of standing balance. Design: Planned secondary analysis of a prospectively registered (NCT01362049), randomized controlled trial with a blinded assessor. Method: Sixty-eight subjects with chronic, recurrent, non-specific LBP were allocated to perform a postural response task as a secondary assessment one week before and one week after receiving either stabilization or Movement System Impairment (MSI)-directed treatment over 6 weekly 1-h sessions plus home exercises. For assessment, subjects completed the Oswestry disability and numeric pain rating questionnaires and then performed a postural response task of maintaining standing balance in response to 3 trials in each of 4 randomly presented directions of linear surface translations of the platform under the subjects' feet. Integrated amplitudes of surface electromyography (EMG) were recorded bilaterally from the rectus abdominis (RA), internal oblique (IO), and external oblique (EO) muscles during the postural response task. Results: No significant effects of treatment on EMG responses were evident. Oswestry and numeric pain ratings decreased similarly following both treatments. Conclusions: Stabilization and MSI-directed treatments do not affect trunk EMG responses to perturbations of standing balance in people with LBP, suggesting current methods of motor retraining do not sufficiently transfer to tasks of reactive postural control.

Thus, our objective was to evaluate the effects trunk stabilization vs. general strength and conditioning exercises on the automatic postural response in persons with chronic low back pain (LBP).Fifty-eight subjects with chronic, recurrent LBP (n=58) (i.e., longer than six months) were recruited and randomly assigned to one of two, 10-week physical therapy programs: stabilization (n=29) or strength and conditioning (n=29). Pain and function were measured at 11 weeks and 6 months post-treatment initiation. To quantify postural following support surface perturbations, surface electrodes recorded electromyography (EMG) of trunk and leg muscles and force plates recorded forces under the feet, to calculate the center of pressure.Both groups demonstrated significant improvements in pain and function out to 6 months. There were also changes in muscle activation patterns immediately post-treatment, but not at 6 months. However, changes in center of pressure (COP) responses were treatment specific. Following treatment, the stabilization group demonstrated later onset of COP displacement, while the onset of COP displacement in the strengthening group was significantly earlier following treatment.Despite two different treatments, clinical improvements and muscle activation patterns were similar for both groups, indicating that the stabilization treatment protocol does not preferentially improve treatment outcomes or inter-muscle postural coordination patterns for persons with LBP.

With modern amplifiers and digital sound recording systems, measurements during physical activity both inside and outside a laboratory setting are now possible and accurate. Muscle sound gives a representation of the work of each muscle group during a complex movement, and under certain forms of movement even reveals both concentric and eccentric activity, something that sEMG is incapable of. Recent findings suggest that AMG has a number of advantages over sEMG, being simple to use, accurate and repeatable as well as being intuitive to interpret. The AMG signal comprises three physiological parameters, namely efficiency/coordination (E-score), spatial summation (S-score) and temporal summation (T-score). It is concluded that modern AMG units have the potential to accurately assess patients with neuromuscular and musculoskeletal complaints in hospital clinics, home monitoring situations as well as sports settings.

This study compared coordination of forearm muscles (muscle synergies) during repeated gripping between individuals with and without lateral epicondylalgia. Methods Twelve participants with lateral epicondylalgia and 14 controls performed 15 cyclical repetitions of sub-maximal (20% maximum grip force of asymptomatic arm), pain free dynamic gripping in four arm positions: shoulder neutral with elbow flexed to 90degree and shoulder flexed to 90degree with elbow extended both with forearm pronated and neutral. Muscle activity was recorded from extensor carpi radialis brevis/longus, extensor digitorum, flexor digitorum superficialis/profundus, and flexor carpi radialis, with intramuscular electrodes. Muscle synergies were extracted using non-negative matrix factorisation. Findings Analysis of each position and participant, demonstrated that two muscle synergies accounted for > 97% of the variance for both groups. Between-group differences were identified after electromyography patterns of the control group were used to reconstruct the patterns of the lateral epicondylalgia group. A greater variance accounted for was identified for the controls than lateral epicondylalgia (p = 0.009). This difference might be explained by an additional burst of flexor digitorum superficialis electromyography during grip release in many lateral epicondylalgia participants. Interpretation These data provide evidence of some differences in synergistic organisation of activation of forearm muscles between individuals with and without lateral epicondylalgia. Due to study design it is not possible to elucidate whether changes in the coordination of muscle activity during gripping are associated with the cause or effect of lateral epicondylalgia.

The paraneoplastic form is associated with small-cell lung cancer in 50-60% of cases, whereas the remaining cases are found in younger adults with a higher likelihood of coexisting autoimmune disease. The early recognition of LES is crucial for improving clinical outcomes but remains a major challenge. In this review, we analyze the clinical characteristics and diagnostic considerations in treating LES through a series of three case studies, one of which showed definitive response to pyridostigmine and corticosteroid combination therapy, followed by spontaneous remission. Patients were assessed by image-based screening, serological testing and electrophysiological evaluations, which included respiratory and autonomic testing. A better understanding of the common pitfalls in the clinical, serological and neurophysiologic diagnosis of LES through assessment of typical LES dysfunction throughout the nervous system should enable improved recognition and treatment of this syndrome.

Methods: Twelve volunteers with nonspecific neck pain and 12 agematched and sex-matched healthy individuals participated. Submaximal symmetrical and asymmetrical bilateral jaw clenching was performed with and without visual feedback of force. Force performance was assessed with indices of accuracy (mean distance, offset error) and precision (standard deviation, coefficient of variation of force). High-density, 2-dimensional, surface electromyography (EMG) was recorded to characterize bilateral masseter muscle activity. The EMG root mean square was computed for each location of the electrode grid to form a map of the EMG amplitude distribution, and the location of the center of activity was measured. Results: The patient group showed a different distribution of masseter muscle activity compared with pain-free individuals during both symmetrical and asymmetrical bilateral jaw clenching. The position of the center of activity was positioned more cranial (P < 0.001; right masseter only) and more anteriorly in the patient group (P < 0.0001). In addition, the patients with chronic neck pain displayed higher levels of masseter muscle activation compared with the control participants regardless of the specific task performed (P < 0.0001). Discussion: People with chronic neck pain display increased activation and altered distribution of masseter muscle activity during a jaw-clenching coordination task. These results provide a greater appreciation of how secondary orofacial pain or temporomandibular disorders may develop in people with neck pain. Copyright © 2016 Wolters Kluwer Health, Inc.

A cross-sectional study between subgroups of non-specific chronic low back pain (NSCLBP) and asymptomatic controls.Objective. To investigate NSCLBP subgroup differences in spinal position sense and trunk muscle activity when repositioning thoracic and lumbar spine into neutral (mid-range) spinal position during sitting and standing.Summary of Background Data. Patients with NSCLBP report aggravation of symptoms during sitting and standing. Impaired motor control in NSCLBP, associated with sitting and standing postures nearer the end-range of spinal motion, may be a contributing factor. Rehabilitation improving neutral (mid-range) spinal position control is advocated. Postural and motor control alterations vary in different NSCLBP subgroups, potentially requiring specific postural interventions. There is limited evidence on whether subgroup differences exist when performing neutral spine position tasks.Methods. Ninety patients with NSCLBP and 35 asymptomatic controls were recruited. Two blinded practitioners classified NSCLBP into subgroups of active extension pattern (AEP) and flexion pattern (FP). Participants were assisted into neutral spine position and asked to reproduce this position 4 times. Absolute, variable and constant errors were calculated. Three-dimensional thoracic and lumbar kinematics quantified the repositioning accuracy and surface electromyography assessed back and abdominal muscles activity bilaterally.Results. Irrespective of subclassification, patients with NSCLBP produced significantly greater error magnitude and variability than the asymptomatic controls but subgroup differences were detected in the error direction. Subgroup differences in the trunk muscle activity were not consistently identified. Whilst both subgroups produced significantly higher abdominal activity, subclassification revealed difference in superficial multifidus activity during standing, with FP producing significantly greater activity than the asymptomatic controls.Conclusion. Subgroups of NSCLBP had similar neutral spinal position deficits regarding error magnitude and variability, but subclassification revealed clear subgroup differences in the direction of the deficit. The trunk muscle activation was shown to be largely non-discriminatory between subgroups with exception of superficial lumbar multifidus.

Studies agree that control of movement is impaired by pain. It is hypothesized that movement is modified to reduce stress on painful tissue to protect from further pain and/or injury. Although this hypothesis is logical, it has never yet been tested. Analysis of the literature shows that, although reduced stress within painful tissue is certainly the goal of these motor adaptations; it is not always achieved. Aside from this biomechanical objective, motor adaptations depend on the subject's sociopsychological context, which may partly explain observed inter-individual variation in adaptation. Finally, we report some recent results suggesting that, while motor adaptation may provide short-term benefit, they can have deleterious long-term negative consequences.

Coordination of the transverse abdominis (TrA), a deep postural muscle, has been shown to be reduced in persons with low back pain. No previous research has studied the effect of age on the activation on this muscle. Objective: To assess the effect of age on TrA activation in response to rapid arm abduction. Design: Cross-sectional cohort study. Setting: University exercise physiology laboratory. Participants: A total of 18 adult men (aged 27 +/- 7.0 years) for the younger group and 11 older adults (5 men and 6 women, aged 59.6 +/- 4.0 years) were recruited for this study. Method: Participants were positioned on a treatment table and performed a series of rapid arm abduction movements with their right arm while the activation of the TrA muscle was recorded using ultrasound imaging. Onset of arm abduction was measured using surface electromyography and synchronized with the ultrasound through the ultrasound unit's electrocardiogram channel. The mean time difference between the 2 events was calculated during post-hoc analysis. Main Outcome Measurements: A Mann-Whitney test was performed to test for differences in the onset performance of the TrA muscle between the 2 groups. Results: Results showed that the older group was significantly slower than the younger group in engaging their TrA in response to the rapid arm abduction (P = .036). A separate analysis of the older group data showed that no significant differences existed between the male and female participants that could potentially have acted as a confounding factor for the main finding (P = .126). Conclusions: This study shows that older adults were slower than younger adults in activating their TrA muscle in response to rapid arm abduction. This delay has the potential to lead to increased occasions when the low back is unprotected, increasing the likelihood of injury or low back pain.

Currently, there is no consensus on the definition of 'statin myopathy'. Evidence suggests that deleterious effects may also be associated with the volume or dosage of structured exercise and/or the intensity of physical activity. Moreover, non-muscle adverse effects on the joints and tendons are often overlooked and underemphasized. The incidence of myopathy associated with statin treatment typically ranges between 1.5% and 10%. Few data are available regarding the prevalence of muscle- related symptoms associated with different statins and the distribution of affected muscles. Furthermore, discrepancies between clinical trials and daily practice may emanate, in part, because of inconsistent definitions or exclusion criteria. The pathophysiology of statin-related myopathy is incompletely understood. A dose-dependent and proapoptotic effect, direct effects on mitochondria, drug interactions and genetic factors, or combinations thereof, may be involved. Recently, a rare immune-mediated myopathy triggered by statin use has been described. With the increasing number of patients treated with statins and with more patients being prescribed high doses of potent statins to achieve low-density lipoprotein targets, muscle-related side-effects will become more prevalent. Currently, the only effective treatment is the discontinuation of statin use. Further research is needed to develop alternative LDL-lowering drugs when statins are not well tolerated and to establish additional effective strategies to manage lipids and lipoproteins.

We wanted to investigate whether electromyography (EMG) was useful for this group in the diagnosis or therapy of radiculopathy. Our aim was to investigate the correlation and classification of EMG and magnetic resonance imaging (MRI) findings in the diagnosis of suspected radiculopathy. Materials and Methods: We included 74 patients with a >=2-month history of numbness and pain in the neck and back that radiated into the arm or leg. Patients with diabetes mellitus, previous disc or spine operation, polyneuropathy, spinal cord diseases (tumor, infection or syrinxs), motor deficits, and abnormal nerve conduction studies were excluded. Results: The mean age of the patients was 51.58 +/- 11.53 years. In total, 41 (55.4%) patients were women and 33 (44.6%) were men; 48.8% (n=36) showed cervical radiculopathy and 51.2% (n=38) exhibited lumbosacral radiculopathy. The most common MRI finding was protrusion (37.8%), and the most common EMG finding was re-innervation (59.5%). The correlation of MRI and EMG findings was significant in lumbar radiculopathy (p=0.007), but not in the cervical radiculopathy results (p=0.976). Conclusion: EMG and MRI findings were compatible for lumbar radiculopathy, but not for cervical radiculopathy in mild to moderate grades. Copyright © 2016, Turkish Neurological Society.

This study investigated whether the amplitude of trunk muscle activation differs between persons with chronic LBP and healthy individuals during walking, and whether changes in muscle activation were related to pain catastrophizing. Thirty persons with chronic non-specific LBP, stratified into 2 groups of high (HLBP) and low (LLBP) pain catastrophizing, were contrasted with a control group of 15 healthy individuals during walking on a treadmill at a self-selected speed. Surface electromyographic (EMG) data were recorded from 10 trunk muscles. The effects of Group and gait Sub-phase on EMG activation amplitudes were assessed. The HLBP group exhibited higher activation of certain muscles throughout the gait cycle, and reduced variability of others at specific sub-phases of gait. A significant correlation was found between activation amplitude and pain catastrophizing in most muscles, when controlling for gait speed and pain intensity. These data indicate that altered trunk muscle activation is present in some patients with LBP during walking, but does not represent a universal increase in activation for all muscles. This altered neuromotor control is, however, more strongly associated with pain catastrophizing than with pain intensity, and appears to represent a non-functional, maladaptive behavior, as it alters the normal, phasic pattern of activation in certain trunk muscles.

Mutations in the selenoprotein N1-encoding gene (SEPN1) and ryanodine receptor 1-encoding gene (RYR1) are responsible for half of the reported cases. Mutations in multiple epidermal growth factor-like domains 10-encoding gene (MEGF10) have been identified only recently in a few patients with antenatal to infantile-onset myopathy, with and without minicore pathology. Methods: We report 2 sisters with adult-onset respiratory insufficiency followed by development of limb weakness. Both had scoliosis, distal joint hyperlaxity, and high-arched feet. Results: A biopsy of the right triceps muscle in 1 sister showed multiple minicore structures. She had electromyographic changes of myopathy with fibrillation potentials and myotonic discharges. Next generation sequencing identified novel compound heterozygous missense variants in MEGF10 c.230G>A (p.Arg77Gln) and c.1833T>G (p.Cys611Trp) in both sisters. Conclusions: MEGF10 mutations can cause myopathy with adult-onset respiratory insufficiency. Copyright © 2016 Wiley Periodicals, Inc.

It is unclear if this is also true during functional locomotor perturbations such as changing direction, or if this change in coordination adaptability persists between symptomatic episodes. The purpose of this study was to compare trunk-pelvis coordination during walking turns in healthy individuals and asymptomatic individuals with a history of low back pain. Methods Participants performed multiple ipsilateral turns. Axial plane inter-segmental coordination and stride-to-stride coordination variability were quantified using the vector coding technique. Frequency of coordination mode and amplitude of coordination variability was compared between groups using Wilcoxon signed-rank tests and paired t-tests respectively. Findings During stance phase of the turn, there was no significant difference in either inter-segmental coordination or coordination variability between groups. Inter-segmental coordination between the trunk and the pelvis was predominantly inphase during this part of the turn. During swing phase, patterns of coordination were more diversified, and individuals with a history of low back pain had significantly greater trunk phase coordination than healthy controls. Coordination variability was the same in both groups. Interpretation Changes in trunk-pelvis coordination are evident between symptomatic episodes in individuals with a history of low back pain. However, previously demonstrated decreases in coordination variability were not found between symptomatic episodes in individuals with recurrent low back pain and therefore may represent a response to concurrent pain rather than a persistent change in motor control.

This paper presents the development of a lightweight portable robotics elbow brace device that fits snugly onto Asian patients with weak upper-limb impairment for repetitive elbow flexion and extension rehabilitation without the presence of the therapists. The device is integrated with surface electromyogram (S-EMG) sensors for assistive & assessment purpose, LabVIEW based interface and built in signal processing module for interactive actuation of device. A secondary anthropometric data are mainly collected from Asian subjects with age ranges of 18 to 60 years & above and statistically analysed to use as a design guideline. Pilot clinical trial was carried out with post-stroke patients to access a safety aspect of using the device and evaluate the performance of the device in terms of a valuable therapist's time saving, usage of bio-feedback for active assistive & assessment, usability and users' perception towards using robotics device in rehabilitation. Both experimental condition data and qualitative results are presented and a pain numeric rating scale (NRS) is used for pain assessment tool. Copyright © 2016 Int. J. Pharm. Med. Biol. Sci.

Twenty-five female FM patients and 25 age- and sex-matched healthy controls (HCs) performed three precision motor tasks: (1) maintain a steady shoulder abduction angle of 45degree while receiving visual feedback about upper arm position and supporting external loads (0.5, 1, or 2 kg), (2) maintain the same shoulder abduction angle without visual feedback (eyes closed) and no external loading, and (3) a joint position sense test (i.e., assessment of proprioceptive accuracy). Patients had more extensive increase in movement variance than HCs when visual feedback was removed (P < 0.03). Proprioceptive accuracy was related to movement variance in HCs (R >= 0.59, P <= 0.002), but not in patients (R <= 0.25, P >= 0.24). There was no difference between patients and HCs in coherence between sEMG and acceleration data. These results may indicate that FM patients are more dependent on visual feedback and less reliant on proprioceptive information for upper limb posture control compared to HCs.

Shoulder pain is among the symptoms associated with TMD. The purpose of this study was to investigate the association between TMD and rotator cuff disease (RCD) and related genetic aspects. All subjects underwent orofacial and shoulder examinations. The control group comprised 30 subjects with no pain. Affected subjects were divided into three groups: RCD (TMD-free, n = 16), TMD (RCD-free, n = 13), and TMD/RCD (patients with both RCD and TMD, n = 49). A total of eight single nucleotide polymorphisms in the ESRRB gene were investigated. A chemiluminescent immunoassay was used to measure estradiol levels. Surface electromyography recorded head and cervical muscle activity. The chi2 test and Student t-test/Mann-Whitney test were used to assess the significance of nominal and continuous variables. A P-value of <0.05 was considered significant. TMD subjects were seven times more susceptible to RCD than controls. The rs1676303 TT (P = 0.02) and rs6574293 GG (P = 0.04) genotypes were associated with RCD and TMD, respectively. TMD/RCD subjects showed associations with rs4903399 (P = 0.02), rs10132091 (P = 0.02), and CTTCTTAG/CCTCTCAG (P = 0.01) haplotypes and lower muscle activity. Estradiol levels were similar among groups. This study supports TMD as a risk factor for RCD. ESRRB haplotypes and low muscle activity are common biomechanical characteristics in subjects with both diseases. Copyright © 2015 International Association of Oral and Maxillofacial Surgeons.

The cerebellum may provide a target for neuromodulation as a therapeutic intervention in cervical dystonia. Objective: This study aimed to assess effects of intermittent theta-burst stimulation of the cerebellum on dystonia symptoms, quality of life, hand motor dexterity and cortical neurophysiology using transcranial magnetic stimulation. Methods: Sixteen participants with cervical dystonia were randomised into real or sham stimulation groups. Cerebellar neuromodulation was combined with motor training for the neck and an implicit learning task. The intervention was delivered over 10 working days. Outcome measures included dystonia severity and pain, quality of life, hand dexterity, and motor-evoked potentials and cortical silent periods recorded from upper trapezius muscles. Assessments were taken at baseline and after 5 and 10 days, with quality of life also measured 4 and 12 weeks later. Results: Intermittent theta-burst stimulation improved dystonia severity (Day 5, -5.44 points; p = 0.012; Day 10, -4.6 points; p = 0.025), however, effect sizes were small. Quality of life also improved (Day 5, -10.6 points, p = 0.012; Day 10, -8.6 points, p = 0.036; Week 4, -12.5 points, p = 0.036; Week 12, -12.4 points, p = 0.025), with medium or large effect sizes. There was a reduction in time to complete the pegboard task pre to post intervention (both p < 0.008). Cortical neurophysiology was unchanged by cerebellar neuromodulation. Conclusion: Intermittent theta-burst stimulation of the cerebellum may improve cervical dystonia symptoms, upper limb motor control and quality of life. The mechanism likely involves promoting neuroplasticity in the cerebellum although the neurophysiology remains to be elucidated. Cerebellar neuromodulation may have potential as a novel treatment intervention for cervical dystonia, although larger confirmatory studies are required.

Characterizing relative scapular muscle activity deficits in participants with shoulder pain will provide foundational knowledge to develop rehabilitation programs. Methods Participants were recruited with subacromial pain syndrome and an asymptomatic control group matched for age, gender, and dominant arm (N=56). Surface electromyographic muscle activity was recorded from the upper, middle, and lower trapezius (UT, MT, LT) and serratus anterior (SA) during 5 repetitions of a weighted arm elevation task. Muscle activity was normalized to a reference contraction and then expressed as UT/MT, UT/LT, UT/SA, and LT/SA ratios. Ratios were compared between groups and across 3 arm angle intervals during ascending and descending elevation. Results A 2x3 mixed-model analysis of variance yielded a group main effect for the UT/LT ratio, with a higher ratio in the subacromial pain group during ascending (mean difference,0.92; P=.008) and descending (mean difference,0.70; P=.030). For the LT/SA ratio, there was a group effect: a lower ratio in the subacromial group during ascending (mean difference,-0.25; P=.026) and descending (mean difference,-0.51; P=.032). There were no differences for the UT/MT or UT/SA. Discussion There is a disruption in coordination between the LT and SA and the UT and LT during an arm elevation task in patients with subacromial pain syndrome. The LT was part of both altered ratios, indicating the relative importance of the LT. Future research should determine if exercises aimed at restoring the dysfunctional LT/SA and UT/LT force couples are beneficial to reduce shoulder pain and disability in patients with unilateral shoulder pain.

Thirteen identified MODY variants differ from each other by the clinical course and treatment requirement. Currently, MODY subtypes 1-5 are best-studied, descriptions of the other forms are sporadic. This article reports a MODY12 clinical case, caused by a mutation in the gene of the ATP-binding cassette transporter sub-family C member 8 (ABCC8), encoding sulfonylurea receptor 1. Diabetes manifested in a 27-year-old non-obese man with epilepsy in anamnesis. No evidence of ketosis was present, pancreatic antibodies were undetectable, and C-peptide remained within the reference range. During the initial investigation, non-proliferative diabetic retinopathy and elevated albumin excretion rate was revealed. After 4 months, diabetes was complicated by pre-proliferative retinopathy and diabetic macular edema. Recurrent hypoglycemia and an increase in body weight was observed on moderate and even small insulin doses. Taking into account the clinical features and the presence of diabetes in four generations on the maternal side, screening for all MODY subtypes was performed. A mutation in the ABCC8 gene was found in proband and in his mother. After the insulin discontinuation, gliclazide modified release combined with sodium/glucose cotransporter 2 (SGLT2) inhibitors was started. This treatment eliminated hypoglycemia and improved glycemic variability parameters. A decrease in the amplitude of glucose excursions was documented by continuous glucose monitoring. After 3 months of treatment, glycemic control was still optimal, and no hypoglycemic episodes were observed. The case report demonstrates the clinical features of ABCC8-associated MODY and the therapeutic potential of a combination of sulfonylurea with SGLT2 inhibitor in this disease.

The 9 patients in this series presented to the tertiary referral airway and voice services of 2 hospitals in London, United Kingdom, from 2012 to 2015. Five patients presented with dysphagia, 1 patient with dysphonia, 1 patient with impaired vocal cord mobility, 1 patient with chronic throat pain, and the last patient with glottic and subglottic stenosis. Routine investigations such as nasal and upper gastrointestinal endoscopy, pH studies, laryngeal electromyography, and radiologic investigations were of limited diagnostic value in the evaluation of these patients' complaints. Clinical findings on examination of the upper aerodigestive tract were also subtle, such as that of generalized laxity of laryngeal and esophageal musculature and incoordination of vocal fold movement. Management of these patients was mainly conservative and included therapy and counseling. Surgical intervention was undertaken in 3 of these cases to improve the airway and swallowing. Laryngologic and upper digestive tract complaints are relatively common, although varied, in Ehlers- Danlos syndrome; hence, awareness of the other systemic manifestations of the syndrome would aid the laryngologist faced with a diagnostic dilemma in a yet-undiagnosed patient.

No major neurovascular complications have been reported using this technique. In Cooled RFA, the temperature of the probe is reduced with circulating water, allowing for more energy use, and creation of a larger burn lesion. The larger burn area is purported to better account for the variability in the anatomic location of the target nerves and increase the efficacy of the procedure. We present a case where despite the use of recommended safety measures cooled radiofrequency lesioning at the hip resulted in severe femoral nerve injury and quadriceps paralysis. Method This is a 25 y/o female who presented with chronic right hip pain secondary to Femoroacetabular impingement syndrome She had no other significant PMH. She underwent hip arthroscopy one year previously which improved but did not eliminate her pain. Her pain continued despite extensive post op physical therapy, chiropractic treatment, and acupuncture. Her medications included only NSAID's prn. She was 5'8", 117lbs, and had a BMI of 19. She had no focal neuro deficits. Following effective diagnostic blocks of the intended nerves, Cooled RFA was performed. Safety measures employed included ultrasound imaging to locate neurovascular structures and marking 1cm wide margins on the skin, a lateral approach to pass under the neurovascular bundle, and motor testing to 2V at 2Hz without evidence of motor stimulation. Results Despite the safety measures employed, the patient developed quadriceps weakness immediately following the procedure with numbness along the femoral and saphenous nerve distribution. These symptoms persisted and physical exam 3 days later revealed 0/5 right knee extension. EMG performed at 6 weeks demonstrated no voluntary motor unit action potentials consistent with severe femoral neuropathy. There was no significant functional recovery over several months of physical therapy, gait training, and external muscle stimulation. Pt was ultimately referred to Neurosurgery, and a nerve transfer vs grafting is planned. Conclusions In this case multiple safety measures were used, but nerve injury still occurred bringing in to question the safety of cooled RF lesioning for hip pain. Exactly how the injury occurred is unclear, but with cooled RF it may be that the burn size extends beyond the area tested with motor stimulation providing a false reassurance of safety. Measures to minimize risk in the future when performing RFA for hip pain include verifying final needle position with ultrasound prior to treatment, limiting local anesthetic volume, and considering pulsed or traditional RFA in patients with low BMI's.

The prevalence is estimated from 1-7.7 per 100,000, is more common in males and rises with age. Usual symptoms are loss of strength and sensation, difficulty climbing stairs, raising arms, pain, and imbalance. Older patients usually have a slow progressive distal pattern, unlike younger patients where proximal weakness is more common. Usually a sensory or combination of sensory and motor involvement are present in older patients versus predominantly motor symptoms in younger patients. Treatment consists of IVIG, plasmapheresis, and/or corticosteroids. Long-term prognosis data is limited but two-thirds of patients respond to a single standard therapy. Case A 70 year old female with history of two episodes of AIDP who continued to have an inflammatory neuropathy consistent with CIDP. In 1993 she had an episode of sensory loss following a flu-like illness and established care with the neuromuscular clinic. A nerve biopsy revealed vasculitis. EMG in 2002 showed sensory greater than motor axonal neuropathy. She has had multiple hospitalizations for CIDP, treated with IVIG and Solumedrol. Her neuropathy limits her mobility and produces a disabling tremor; PACE is providing home care for chore services and bathing. IVIG infusion is currently being provided to her at home through PACE, but there have been several instances where it was difficult to get home infusions. Discussion Geriatricians should know that CIDP is more common with age and can cause gait abnormalities and motor/sensory deficits, limiting functional independence. Challenges in providing home IVIG infusion include ensuring safe administration, cost of therapy, home care agencies administering infusions, and coordination among patients, healthcare providers, and health plans. Medicare requires a diagnosis of primary immune deficiency and the physician must decide that it's medically appropriate for home IVIG therapy. Part B covers IVIG, but doesn't pay for the services and items related to the infusion. Any Infusions not covered by part B could be covered by part D. Most plans that cover IVIG at home require prior authorization. These challenges can delay treatment; thus, geriatricians need to be aware of them.

LEARNING OBJECTIVE #2: Describe the diagnostic approach to neurosarcoidosis. CASE: A 31 year old African American male with no significant past medical history presented with a 2 month history of constant headache and a migrating Bell's palsy. Two months prior to evaluation, patient experienced a facial palsy of his right lower face associated with dysarthria of complex words. One week later, he developed a persistent headache (8/10 in severity). Additional symptoms included a dry cough, swollen right preauricular lymph node, right eye blurred vision, and photosensitivity. Three weeks later, his left lower face became paralyzed, associated with left eye blurred vision, photosensitivity, and lagophthalmos. As he developed left-sided palsy, he regained motor function in the right lower face, but noted persistent tingling and numbness. Headache, tinnitus, dizziness, and left-sided facial palsy continued to presentation. Prior to admission, the patient took prednisone to reduce his facial palsy symptoms. He denied seizures, memory loss, coordination impairments, skin rashes, joint pain, fever, fatigue, shortness of breath, wheezing, or hemoptysis. On physical exam, patient was alert and oriented. Cranial nerve (CN) examination revealed normal bilateral sensation to light touch. Unable to smile on left, normal movement on right. Right cheek could puff air, but it seeped out of the left side of the mouth. Left eye could be pried open. All other cranial nerves intact. Babinski sign positive in left foot. Exam otherwise unremarkable except for minimal expiratory wheezing in the right lower lobe. Contrast MRI of the brain revealed a cyst in the corpus callosum and enhancement around right Meckel's cave and right CN VII extending into the proximal right mandibular nerve. Chest CT showed bilateral centrilobular pulmonary nodules with mediastinal and hilar lymphadenopathy. A fine needle biopsy of mediastinal lymph nodes indicated epithelioid granulomas consistent with sarcoidosis. CSF analysis revealed elevated protein and leukocytosis (95 % lymphocytes) with normal glucose. Infectious workup was negative. Patient was started on 60 mg oral prednisone once daily to be tapered every 2 weeks. Given no improvement at 6 weeks, methotrexate was added for long-term immunosuppression. DISCUSSION: Sarcoidosis is an idiopathic multisystemic non-infectious inflammatory disorder characterized by noncaseating granulomas. Only 5-10 % of patients with systemic sarcoidosis have neurological complications resulting in neurosarcoidosis (NS). However post-mortem studies indicate central nervous system (CNS) involvement in up to 25 %, suggesting the underdiagnosis of NS. Clinical diagnosis relies on the Zajicek criteria, which defines the likelihood of a NS diagnosis as definitive, probable, or possible, based on the amount of evidence. Noncaseating granulomas in the CNS are the histopathological hallmark of NS and are the only definitive diagnostic marker, however biopsy of brain parenchyma is highly invasive. Neurosarcoidosis is probable when neurological inflammation is concurrent with systemic disease and possible as a diagnosis of exclusion when patients present with typical neurological symptoms. Neurosarcoidosis most commonly manifests as cranial nerve abnormalities, especially optic (CN II) and facial (CN VII) neuropathies. Vestibulocochlear (CN VIII) and trigeminal (CN V) neuropathies may also present, resulting in facial sensory loss, hearing loss, and dizziness. Aseptic meningitis is the next most common neurological sign of sarcoidosis. Patients may less commonly display hypothalamic-pituitary dysfunction, encephalopathies, seizures, focal deficits due to mass effect of cerebral lesions, cerebral vasculopathy, and peripheral neuropathies or myopathies. Since no individual non-invasive test is specific for NS, practitioners should utilize a wide scope of diagnostic tools to confidently differentiate NS from neoplasms, inflammatory diseases, and infections. When NS is suspected, contrast enhanced T1-weighted MRI is the most sensitive and preferred diagnostic imaging technique. Basilar leptomeningeal enhancement is most often observed on MRI, but other common findings include focal lesions, diffuse dural thickening, hypothalamic-pituitary enhancement, and cranial nerve enhancement. Cerebrovascular findings, hydrocephalus, and spinal cord lesions are less common. CSF analysis may reveal elevated protein or white blood cells, decreased glucose, and increased IgG; however, increased sIL2-receptor alpha chain levels >150 pg/mL and elevated ACE are the most specific findings in the CSF for NS. Electromyography may be used to determine peripheral nervous system involvement. Malignancy and infectious meningitis can result in MRI and CSF findings similar to NS. Therefore, cytology, flow cytometry, and cultures are used to rule out these processes. Lymphadenopathy and nodules on chest, abdomen, and pelvis CT can be indicative of systemic sarcoidosis and add further evidence to the overall clinical and diagnostic picture for neurosarcoidosis.

She reported dysphagia to both solids and liquids and decreased taste with poor appetite for the last several years. She started to lose weight ultimately losing 80 pounds over 2 years. As her weight loss progressed, she began to have generalized weakness with difficulty walking and multiple falls. Ultimately severe malnutrition required gastric tube placement for supplemental nutrition. She also reported longstanding constipation alternating with diarrhea and chronic joint hypermobility and joint dislocation. Past medical history was notable for gastroparesis, abdominal hernia, and mild cognitive impairment. Family history included hypermobile joints in her grandmother, mother, and brother. She had an extensive work-up at multiple outside institutions over the last 2 years including unremarkable EMG, MRI brain/spinal cord, HIDA scan, lumbar puncture, infectious disease evaluation, autoimmune panel, EGD and colonoscopy evaluation without a clear diagnosis. In the past her symptoms were attributed to anorexia nervosa or psychosomatic disorders as a cause for her significant weight loss and failure to thrive. Exam was notable for an extremely cachectic appearing female. She had decreased strength in her upper and lower extremity with atrophy of her extremities with normal tone. She had impaired sensation in the feet and hands to light touch and pinprick. She had hypermobility of multiple joints without evidence of skin hyperextensibility. Laboratory studies were unremarkable. Based on the clinical history and exam findings, she was diagnosed with Ehlers Danlos Syndrome Type III (Hypermobility Type). DISCUSSION: Ehlers Danlos Syndrome is an autosomal dominant connective tissue disease than affects as many as one in five thousand individuals. Clinical history may include complaints of joint pain affecting multiple joints and recurrent dislocation. A majority of patients experience chronic fatigue and chronic pain which can cause significant disability and may be the most bothersome complaint to the patient. Other common manifestations include poor wound healing with frequent bruising. Neurological complaints may also include neuropathies, impaired motor development, gait instability, headache, mild cognitive impairment and myalgias with accompanying weakness. Gastrointestinal manifestations are common and can incorporate abdominal hernia, functional bowel disorders such as dysphagia, decreased taste, reflux, chronic constipation, IBS, and poor nutritional status. Diagnosis is largely based on clinical history with family history being a key component, as well as physical examination. Genetic markers have been identified for some subtypes but are not required for diagnosis. Diagnosis for Ehlers Danlos Syndrome is differentiated by subtype but includes both major and minor criteria. Major criteria include skin involvement with hyperextensibility, generalized joint hypermobility, and tissue fragility (widened atrophic scars). Minor criteria can include recurrent joint dislocation, subcutaneous spheroids, chronic joint/limb pain, molluscoid pseudotumors, and a positive family history for joint complaints. Other reported associated symptoms may include functional bowel disorders, gastrointestinal dysautonomia, easy bruising, muscle hypotonia, hernias, mitral valve prolapse, or aortic dilation. This case highlights the constellation of systemic manifestations seen in Ehlers Danlos Syndrome. Due to variability and nonspecific nature of many of the systemic findings, diagnosis often being missed, delayed or symptoms incorrectly attributed to psychosomatic illness. Physicians need to be aware of the range of clinical manifestations of Ehlers Danlos Syndrome. In this case, a comprehensive history rather than extensive tests was key to making the diagnosis.

We report the clinical and genetic features of a family with two affected siblings and their mother initially diagnosed as "distal SMA". METHODS: We obtained retrospective data from clinical history, neurological examination, electrophysiological testing (EMG) and computerized motion analysis (CMA). A commercial targeted exome sequencing of 50 CMT genes were carried out in the subjects. RESULTS: The initial clinical findings included clumsiness, falling, and foot pain. The older sibling had her first evaluation and EMG at age seven. This showed a "pure" motor axonal neuropathy with denervation. Subsequent clinical examinations of both siblings showed lower extremity predominant distal weakness, no sensory deficits, preserved reflexes and pes cavus. Repeated CMA showed a much milder and less progressive functional gait abnormality in the younger (by 4 years) sibling at 6 and 8 years of age. The CMTPeds score was 18 point higher in the older sibling at 12 years of age. Their mother had a very mild clinical presentation and was able to run long distance. However, she had some distal sensory deficit. Her EMG showed evidence of lower extremity sensorimotor axonal neuropathy with chronic reinnervation. Targeted exome sequencing showed a novel heterozygous duplication of exons 4-6 of MFN2 gene. CONCLUSIONS:We describe a considerable clinical variability in a two-generation family affected by CMT2A. At the onset of disease, the clinical and electrophysiological features were consistent with pure motor axonal neuropathy. Intragenic duplication of MFN2 has never been described as the cause of CMT2A.

However, the underlying mechanisms are not well known. The aim of the present study was to investigate postural control and muscle activation during and as a result of prolonged standing in chronic LBP (cLBP) patients compared to healthy controls (HCs). Body weight shifts and trunk and hip muscle activity was measured during 15 min standing. Prior and after the standing trial, strength, postural sway, reposition error (RE), flexion relaxation ratio (FRR), and pain were assessed and after the prolonged standing, ratings of perceived exertion. During prolonged standing, the cLBP patients performed significantly more body weight shifts (p<.01) with more activated back and abdominal muscles (p=01) and similar temporal variability in muscle activation compared to HCs, while the cLBP patients reported more pain and perceived exertion at the end of prolonged standing. Moreover, both groups had a similar change in strength, postural sway, RE and FRR from before to after prolonged standing, where changes in HC were towards pre-standing values of cLBP patients. Thus, despite a more variable postural strategy, the cLBP patients did not have higher muscle activation variability, but a general increased muscle activation level. This may indicate a reduced ability to individually deactivate trunk muscles. Plausibly, due to the increased variable postural strategy, the cLBP patients could compensate for the relatively high muscle activation level, resulting in normal variation in muscle activation and normal reduction in strength, RE and FRR after prolonged standing.

Methods Trunk muscle activity distribution was evaluated twice, with 3 to 4 days between them, in 27 asymptomatic volunteers using large-array surface EMG. Motor variability, assessed with 2 different variables (the centroid coordinates of the root mean square map and the dispersion variable), was evaluated during a low back muscle fatigue task. Test-retest reliability of muscle activity distribution was obtained using Pearson correlation coefficients. Results A shift in the distribution of EMG amplitude toward the lateral-caudal region of the lumbar erector spinae induced by muscle fatigue was observed. Moderate to very strong correlations were found between both sessions in the last 3 phases of the fatigue task for both motor variability variables, whereas weak to moderate correlations were found in the first phases of the fatigue task only for the dispersion variable. Conclusion These findings show that, in asymptomatic participants, patterns of EMG activity are less reliable in initial stages of muscle fatigue, whereas later stages are characterized by highly reliable patterns of EMG activity.

In this study, we have developed a novel target-matching protocol and used non-negative matrix factorization (NMF) technique to extract trunk muscle synergies and corresponding torque synergies. Isometric torque data at the L5/S1 level and electromyographic patterns of twelve abdominal and back muscles from twelve healthy participants (five females) were simultaneously recorded. Each participant performed a total number of 24 isometric target-matching tasks using 12 different angular directions and 2 levels of uniaxial and biaxial exertions. Within- and between-subject similarities were assessed by considering both the data of different pairs of participants, where the activation coefficients of one participant were used in the NMF analysis of another participant, and the Pearson's correlation coefficients (R) between muscle synergy vectors. The results showed that, for a healthy person, a set of four muscles (overall variance accounted for (VAF) of 97.9+/-0.53%) and four corresponding torque synergies (overall VAF of 92.2+/-3.03%) could efficiently decompose the sagittal and transverse torque planes into their main directions. Furthermore, the correlation coefficients were 0.77+/-0.12, 0.86+/-0.08, 0.78+/-0.12, and 0.93+/-0.04, for all synergies, reflecting the consistency of muscle synergies across participants. Overall, our results suggest that by taking advantage of muscle synergies we could potentially overcome the redundancy inherent to control strategies of the trunk neuromuscular system. In future studies, the synergies identified in patients with low back pain could be compared with those extracted from healthy participants towards various clinical and rehabilitation applications.

The present report describes three families with three different TTR mutations who were followed from 1995 to 2014. Only one of these families expressed the Val30Met mutation, which is the most common mutation in endemic regions; all members of this family had late disease onset but varied severities and clinical presentations of the disease. The second family expressed the Thr49Ser mutation, which has not been well documented previously. Our limited experience obtained from these patients indicates that this mutation presents with autonomic neuropathy but a greater degree of cardiac involvement, especially fatal heart failure. The third mutation, Glu54Lys, has been identified as a cause of severe familial amyloid polyneuropathy; the family members with this mutation exhibited severe motor and autonomic neuropathy, early vitreous opacity, and fatal heart failure. Three of the patients with the Val30Met mutation were treated with tafamidis for longer than one year and cessation of the polyneuropathy resulted. However, a short trial of tafamidis in two patients with the Glu54Lys mutation, who showed severe systemic and neurological involvement, did not gain any clinical benefits.

Sex hormones (ie, estrogens, progestins, androgens) could contribute to extant differences in pain sensitivity between men and women. Despite this, there has been limited experimental research assessing the relationship between pain and sex hormones. The purpose of this study was to extend previous research and examine the association between sex hormones and nociceptive processing in healthy women. Materials and Methods: A total of 40 healthy women were tested during the mid-follicular, ovulatory, and late-luteal phases of the menstrual cycle (testing order counterbalanced). Salivary estradiol, progesterone, and testosterone were collected at each testing session and pain was examined from electrocutaneous threshold/tolerance, ischemia threshold/tolerance, and McGill Pain Questionnaire-Short Form ratings of noxious stimuli. Nociceptive flexion reflex threshold was assessed as a measure of spinal nociception. Results: Overall, there were no significant menstrual phase-related differences in pain outcomes. Nonetheless, variability in testosterone (and to a lesser degree estradiol) was associated with pain; testosterone was antinociceptive, whereas estradiol was pronociceptive. No hormone was associated with nociceptive flexion reflex threshold. Discussion: Although future research is needed to replicate and extend these findings to clinical populations (ie, chronic pain, premenstrual dysphoric disorder), results from the present study indicate that menstrual phase-related changes in sex hormones have minimal influence on experimental pain. However, individual differences in testosterone may play a protective role against pain in healthy women. Copyright © 2014 Wolters Kluwer Health, Inc. All rights reserved.

In twelve volunteers the right m. longissimus was injected by hypertonic and isotonic (control) saline. The pain intensity was assessed on a visual analog scale (VAS). Subjects were seated on a custom-designed chair including a 3-dimensional force sensor adjusted to the segmental height of T1. Electromyography (EMG) was recorded bilaterally from longissimus, multifidus, rectus abdominis, and external oblique muscles. Isometric trunk extensions were performed before, during, and after the saline injections at 5%, 10%, and 20% of maximum voluntary contraction force. Visual feedback of the extension force was provided whereas the tangential force components were recorded. Compared with isotonic saline, VAS scores were higher following hypertonic saline injections (P<. .01). Experimental low back pain reduced the EMG activity bilaterally of the rectus abdominis muscles during contractions at 10% and 20% MVC (P<. .01) although force accuracy and tangential force variability was not affected. Increased variability in the tangential force composition was found during pain compared with the non-painful condition (P<. .05). The immediate adaptation to pain was sufficient to maintain the quality of the task performance; however the long-term consequence of such adaptation is unknown and may overload other structures.

There are a lack of studies about muscle coordination under motor constrains during dynamic contractions. In golf, both handicap (Hc) and low back pain (LBP) are the main factors associated with the occurrence of injuries. The aim of this study was to analyze the accuracy of support vector machines SVM on EMG-based classification to discriminate Hc (low and high handicap) and LBP (with and without LPB) in the main phases of golf swing. For this purpose recurrence quantification analysis (RQA) features of the trunk and the lower limb muscles were used to feed a SVM classifier. Recurrence rate (RR) and the ratio between determinism (DET) and RR showed a high discriminant power. The Hc accuracy for the swing, backswing, and downswing were 94.4 +/- 2.7%, 97.1 +/- 2.3%, and 95.3 +/- 2.6%, respectively. For LBP, the accuracy was 96.9 +/- 3.8% for the swing, and 99.7 +/- 0.4% in the backswing. External oblique (EO), biceps femoris (BF), semitendinosus (ST) and rectus femoris (RF) showed high accuracy depending on the laterality within the phase. RQA features and SVM showed a high muscle discriminant capacity within swing phases by Hc and by LBP. Low back pain golfers showed different neuromuscular coordination strategies when compared with asymptomatic. Copyright © 2015 Elsevier Ltd.

This study investigated the effect of experimental neck pain on the activity of the axioscapular muscles during arm movements and changes in pain sensitivity. Experimental neck pain was induced in 24 healthy volunteers by injecting hypertonic saline into the splenius capitis. Isotonic saline was injected as control. Before, during, and after injections, electromyography was recorded bilaterally from 8 muscles during standardized arm movements (140degree scapular plane elevation), and the root mean square amplitude was extracted. Likewise, pressure pain thresholds were assessed bilaterally on 3 sites. The root mean square electromyography was decreased for the ipsilateral upper trapezius (P <.01) and increased for the ipsilateral middle deltoid (P <.03) during upward movements. The root mean square electromyography was reduced for the ipsilateral upper trapezius (P <.01) during downward movement, whereas an increase was recorded in the contralateral external oblique (P <.02). At the injection site, the pressure pain threshold increased during pain compared with the post condition (5 minutes after potential pain had subsided; P <.03). In this study, trunk and axioscapular muscle activities were reorganized in response to localized and referred pain evoked by hypertonic saline injection into an intrinsic neck muscle with no direct attachments to the trunk or shoulder girdle. Perspective Reorganized activity of the axioscapular muscles has been shown previously in neck pain patients and is believed to happen during the transition from acute to chronic pain. The present study demonstrates for the first time that such reorganization may happen acutely, adding to our understanding of the effects of acute neck pain. Copyright © 2015 American Pain Society.

Whether neuromuscular control changes after surgery remains unclear. The purpose of the study was to identify the muscle activation patterns employed before and after lumbar spinal fusion. Nineteen patients having low back pain and undergoing minimally invasive lumbar spinal fusion were evaluated at 1. day before and 1. month after fusion surgery. Nineteen matched healthy participants were recruited as controls. Patients' pain severity and daily activity functioning were recorded. All participants were instructed to perform forward reaching, and the muscle activities were monitored using surface electromyography (EMG) with sensors placed on both sides of their trunk and lower limbs. The muscle activation patterns were identified using the principal component analysis (PCA). All patients had significant improvements in pain intensity and daily activity functioning after surgery, but exhibited an adaptive muscle activation pattern during forward reaching movement compared with the controls. Significant loading coefficients in the dominant movement pattern (reflected in the first principal component) were observed in back muscles for controls whereas in leg muscles for patients, both pre- and postoperatively. Despite substantial improvements in pain intensity and daily activity functioning after surgery, the patients exhibited decreased paraspinal muscle activities and adaptive muscle coordination patterns during forward reaching. They appeared to rely mainly on their leg muscles to compensate for their insufficient paraspinal muscle function. Early intervention focusing on training paraspinal muscles should be considered after spinal fusion surgery. Copyright © 2015 Elsevier B.V.

Verbal scales, visual analog scales (VAS) or numeric rating scales (NRS) count among the most common tools, which are restricted to patients with normal mental abilities. There also exist instruments for pain assessment in people with verbal and/or cognitive impairments and instruments for pain assessment in people who are sedated and automated ventilated. However, all these diagnostic methods either have limited reliability and validity or are very time-consuming. In contrast, biopotentials can be automatically analyzed with machine learning algorithms to provide a surrogate measure of pain intensity. Methods In this context, we created a database of biopotentials to advance an automated pain recognition system, determine its theoretical testing quality, and optimize its performance. Eightyfive participants were subjected to painful heat stimuli (baseline, pain threshold, two intermediate thresholds, and pain tolerance threshold) under controlled conditions and the signals of electromyography, skin conductance level, and electrocardiography were collected. A total of 159 features were extracted from the mathematical groupings of amplitude, frequency, stationarity, entropy, linearity, variability, and similarity. Results We achieved classification rates of 90.94% for baseline vs. pain tolerance threshold and 79.29% for baseline vs. pain threshold. The most selected pain features stemmed from the amplitude and similarity group and were derived from facial electromyography. Conclusion The machine learning measurement of pain in patients could provide valuable information for a clinical team and thus support the treatment assessment.

As advanced genetic testing is performed, molecular diagnosis can be obtained. Identifying new gene mutations can lead to further understanding of disease. Methods and Results: We report a single case of a patient with earlyonset amyotrophic lateral sclerosis, evaluated at University of Texas Health Houston Science Center from 2011-2014. Initial genetic testing did not reveal an etiology in this patient. Through wholeexome sequencing, a VRK1 mutation was identified. Conclusions and Relevance: We identify a possible new cause of hereditary amyotrophic lateral sclerosis, VRK1 mutation. This case report also expands the phenotypic spectrum of this mutation in neurologic diseases. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.

In this study we evaluate whether an acute noxious stimulus induces a change in the way motor modules are combined to generate movement by neck muscles. The neck region was selected as it is a region with potentially high muscular redundancy. We used the motor modules framework to assess the redistribution of muscular activity of 12 muscles (6 per side) in the neck region of 8 healthy individuals engaged in a head and neck aiming task, in non-painful conditions (baseline, isotonic saline injection, post pain) and after the injection of hypertonic saline into the right splenius capitis muscle. The kinematics of the task was similar in the painful and control conditions. A general decrease of activity was noted for the injected muscle during the painful condition together with an increase or decrease of the activity of the other muscles. Subjects did not adopt shared control strategies (motor modules inter subject similarity at baseline 0.73+/-0.14); the motor modules recorded during the painful condition could not be used to reconstruct the activation patterns of the control conditions, and the painful stimulus triggered a subject-specific redistribution of muscular activation (i.e., in some subjects the activity of a given muscle increased, whereas in other subjects it decreased with pain). Alterations of afferent input (i.e., painful stimulus) influenced motor control at a multi muscular level, but not kinematic output. These findings provide new insights into the motor adaptation to pain. Copyright © 2015 Gizzi et al.

A secondary aim was to determine whether any adaptation was specific to pain location. Sixteen participants walked on a treadmill during 5 conditions [control, low back pain (LBP), washout LBP, calf pain (CalfP), and washout CalfP]. Five muscle synergies were identified for all of the conditions. Cross-validation analysis showed that muscle synergy vectors extracted for the control condition accounted for >81% of variance accounted for from the other conditions. Muscle synergies were altered very little in some participants (n = 7 for LBP; n = 10 for CalfP), but were more affected in the others (n = 9 for LBP; n = 6 for CalfP). No systematic differences between pain locations were observed. Considering all participants, synergies related to propulsion and weight acceptance were largely unaffected by pain, whereas synergies related to other functions (trunk control and leg deceleration) were more affected. Gastrocnemii activity was less during both CalfP and LBP than control. Soleus activity was further reduced during CalfP, and this was associated with reduced plantar flexion. Some lower leg muscles exhibited adaptations depending on pain location (e.g., greater vastus lateralis and rectus femoris activity during CalfP than LBP). Overall, these changes in muscle coordination involve a participant-specific strategy that is important to further explore, as it may explain why some people are more likely to develop persistence of a painful condition.

The pain effects may decrease when the three-dimensional force components are voluntarily adjusted, but it is not known if this could have negative consequences on other structures of the motor system. The present study assessed the effects of acute pain on the force variability during sustained elbow flexion when controlling task-related (one-dimensional) and all (three-dimensional) contraction force components via visual feedback. Experimental muscle pain was induced by bolus injection of hypertonic saline into m. biceps brachii, and isotonic saline was used as control. Twelve subjects performed sustained elbow flexion at different levels of the maximal voluntary contraction (5-30% MVC) before, during, and after the injections. Three-dimensional force components were measured simultaneously with surface electromyography (EMG) from elbow flexors and auxiliary muscles. Results showed that force variability was increased during pain compared to baseline for contractions using one-dimensional feedback (P<. .05), but no significant differences were found for three-dimensional feedback. During painful contractions (1) EMG activity from m. trapezius was increased during contractions using both one-dimensional and three-dimensional feedback (P<. .05), and (2) the complexity of EMG from m. triceps brachii and m. deltoid was higher for the three-dimensional feedback (P<. .05). In conclusion, the three-dimensional feedback reduced the pain-related functional distortion at the cost of a more complex control of synergistic muscles. Copyright © 2014 Elsevier B.V.

In this study, we aimed to investigate the effect of experimental muscle pain on the neural control of muscle force at higher frequency bands, associated with afferent feedback (alpha band, 5-13 Hz) and with descending cortical input (beta band, 15-30 Hz). Single-motor unit activity was recorded, in two separate experimental sessions, from the abductor digiti minimi (ADM) and tibialis anterior (TA) muscles with intramuscular wire electrodes, during isometric abductions of the fifth finger at 10% of maximal force [maximum voluntary contraction (MVC)] and ankle dorsiflexions at 25% MVC. The contractions were repeated under three conditions: no pain (baseline) and after intramuscular injection of isotonic (0.9%, control) and hypertonic (5.8%, painful) saline. The results showed an increase of the relative power of both the force signal and the neural drive at the tremor frequency band (alpha, 5-13 Hz) between the baseline and hypertonic (painful) conditions for both muscles (P < 0.05) but no effect on the beta band. Additionally, the strength of motor unit coherence was lower (P < 0.05) in the hypertonic condition in the alpha band for both muscles and in the beta band for the ADM. These results indicate that experimental muscle pain increases the amplitude of the tremor oscillations because of an increased variability of the neural control (common synaptic input) in the tremor band. Moreover, the concomitant decrease in coherence suggests an increase in independent input in the tremor band due to pain. Copyright © 2015 the American Physiological Society.

The purpose of this study was to compare two normalisation methods, a maximal method (maximum voluntary isometric contraction (MVIC)) and non-maximal peak dynamic method (PDM), on gluteus medius (GMed) activation using sEMG during three weight-bearing exercises in people with hip osteoarthritis (OA) and healthy controls. Thirteen people with hip OA and 20 controls performed three exercises (Squat, Step-Up, Step-Down). Average root-mean squared EMG amplitude based on MVIC and PDM normalisation was compared between groups for both involved and uninvolved hips using Mann-Whitney tests. Using MVIC normalisation, significantly higher normalised GMed EMG amplitudes were found in the OA group during all Step-up and down exercises on the involved side (. p=. 0.02-0.001) and most of the Step exercises on the uninvolved side (. p=. 0.03-0.04), but not the Squat (. p>. 0.05), compared to controls. Using PDM normalisation, significant between-group differences occurred only for Ascending Squat (. p=. 0.03) on the involved side. MVIC normalisation demonstrated higher inter-trial relative reliability (ICCs. =. 0.78-0.99) than PDM (ICCs. =. 0.37-0.84), but poorer absolute reliability using Standard Error of Measurement. Normalisation method can significantly affect interpretation of EMG amplitudes. Although MVIC-normalised amplitudes were more sensitive to differences between groups, there was greater variability using this method, which raises concerns regarding validity. Interpretation of EMG data is strongly influenced by the normalisation method used, and this should be considered when applying EMG results to clinical populations. Copyright © 2014 Elsevier B.V.

Case report and review of literature. Objective. To report the case of a 67-year-old woman who developed delayed onset (6 months) of symptomatic shingles after cervical nerve root decompression in a previously symptomatic dermatome. Methods. The patient's clinic course and outcomes were retrospectively reviewed. The study required no outside funding. The study authors have no financial interest in any of the products or techniques discussed. Results. The patient received definitive treatment for shingles once the zoster form rash manifested. The patient, however, developed postherpetic neuralgia and remained symptomatic at her 2-year postoperative visit. Conclusions. Although shingles is a common disease state affecting patients in the fifth and sixth decades of life, it is rarely seen in the setting of cervical nerve root decompression. This case demonstrates the need to include shingles on the differential diagnosis of recurrent neurogenic pain after anterior cervical decompression and fusion.

However, no study has compared the relative effectiveness of gait parameters for assessing motor performance in low back disorders after surgery. The purpose of the current review was to determine the sensitive gait parameters that address physical improvements in each specific spinal disorder after surgical intervention. Methods Articles were searched with the following inclusion criteria: 1) population studied consisted of individuals with low back disorders requiring surgery; 2) low back disorder was measured objectively using gait assessment tests pre- and post-surgery. The quality of the selected studies was assessed using Delphi consensus, and meta-analysis was performed to compare pre- and post-surgical changes. Findings Thirteen articles met inclusion criteria, which, almost exclusively, addressed two types of spinal disorders/interventions: 1) scoliosis/spinal fusion; and 2) stenosis/decompression. For patients with scoliosis, improvements in hip and shoulder motion (effect size = 0.32-1.58), energy expenditure (effect size = 0.59-1.18), and activity symmetry of upper-body muscles during gait were present after spinal fusion. For patients with spinal stenosis, increases in gait speed, stride length, cadence, symmetry, walking smoothness, and walking endurance (effect size = 0.60-2.50), and decrease in gait variability (effect size = 1.45) were observed after decompression surgery. Interpretation For patients with scoliosis, gait improvements can be better assessed by measuring upper-body motion and EMG rather than the lower extremities. For patients with spinal stenosis, motor performance improvements can be captured by measuring walking spatio-temporal parameters, gait patterns, and walking endurance. Copyright © 2015 Elsevier Ltd.

Changes in motor control caused by pain could affect this ability. This study investigated whether nociceptive stimulation (hypertonic saline injection) in a low back (LBP) or calf (CalfP) muscle affects gait stability. Sixteen participants walked on a treadmill at 0.94ms-1 and 1.67ms-1, while thorax kinematics were recorded using 3D-motion capture. From 110 strides, stability (local divergence exponent, LDE), stride-to-stride variability and root mean squares (RMS) of thorax linear velocities were calculated along the three movement axes. At 0.94ms-1, independent of movement axes, gait stability was lower (higher LDE) and stride-to-stride variability was higher, during LBP and CalfP than no pain. This was more pronounced during CalfP, likely explained by the biomechanical function of calf muscles in gait, as supported by greater mediolateral RMS and stance time asymmetry than in LBP and no pain. At 1.67ms-1, independent of movement axes, gait stability was greater and stride-to-stride variability was smaller with LBP than no pain and CalfP, whereas CalfP was not different from no pain. Opposite effects of LBP on gait stability between speeds suggests a more protective strategy at the faster speed. Although mediolateral RMS was greater and participants had more asymmetric stance times with CalfP than LBP and no pain, limited effect of CalfP at the faster speed could relate to greater kinematic constraints and smaller effects of calf muscle activity on propulsion at this speed. In conclusion, pain effects on gait stability depend on pain location and walking speed. Copyright © 2015 Elsevier Ltd.

Current ways of treatment focus on alleviating symptomatic muscle activity. Besides pharmacological treatment, in severe cases patients may receive neuromodulative intervention such as deep brain stimulation. However, these (highly invasive) methods have some major drawbacks. For the first time, percutaneous auricular vagus nerve stimulation (pVNS) was applied in a single case of primary cervical dystonia. Auricular vagus nerve stimulation was already shown to modulate the (autonomous) sympathovagal balance of the body and proved to be an effective treatment in acute and chronic pain, epilepsy, as well as major depression. pVNS effects on cervical dystonia may be hypothesized to rely upon: (i) the alteration of sensory input to the brain, which affects structures involved in the genesis of motoric and nonmotoric dystonic symptoms; and (ii) the alteration of the sympathovagal balance with a sustained impact on involuntary movement control, pain, quality of sleep, and general well-being. The presented data provide experimental evidence that pVNS may be a new alternative and minimally invasive treatment in primary cervical dystonia. One female patient (age 50 years) suffering from therapy refractory cervical dystonia was treated with pVNS over 20 months. Significant improvement in muscle pain, dystonic symptoms, and autonomic regulation as well as a subjective improvement in motility, sleep, and mood were achieved. A subjective improvement in pain recorded by visual analog scale ratings (0-10) was observed from 5.42 to 3.92 (medians). Muscle tone of the mainly affected left and right trapezius muscle in supine position was favorably reduced by about 96%. Significant reduction of muscle tone was also achieved in sitting and standing positions of the patient. Habituation to stimulation leading to reduced stimulation efficiency was observed and counteracted by varying stimulation patterns. Experimental evidence is provided for significantly varied sympathovagal modulation in response to pVNS during sleep, assessed via heart rate variability (HRV). Time domain measures like the root mean square of successive normal to normal heart beat intervals, representing parasympathetic (vagal) activity, increased from 37.8 to 67.6 ms (medians). Spectral domain measures of HRV also show a shift to a more pronounced parasympathetic activity.

Objective To evaluate whether current motor retraining treatments address LBP-associated changes in movement coordination during tasks that do and do not require APAs. Design Prospectively registered randomized controlled trial with a blinded assessor. Setting Outcome evaluations occurred in a university laboratory; treatments were carried out in outpatient physical therapy clinics. Patients Fifteen subjects without LBP and 33 subjects with chronic, recurrent, and nonspecific LBP. Intervention Twelve subjects with LBP received stabilization treatment, 21 received movement system impairment-based treatment, for more than 6 weekly 1-hour sessions plus home exercises. Measurements Pre- and post-treatment, surface electromyography (EMG) was recorded bilaterally from trunk and leg muscles during unsupported and supported leg-lifting tasks, which did and did not require an APA, respectively. Vertical reaction forces under the contralateral leg were recorded to characterize the APA. Oswestry disability scores and numeric pain ratings were also recorded. Results Persons with LBP demonstrated an impaired APA compared with persons without LBP, characterized by increased premovement contralateral force application and increased postmovement trunk EMG amplitude, regardless of the task. After treatments, both groups similarly improved in disability and function; however, APA characteristics did not change (ie, force application or EMG amplitude) in either task. Limitations Treating clinicians were not blinded to treatment allocation, only short-term outcomes were assessed, and main effects of treatment do not rule out nonspecific effects of time or repeated exposure. Conclusions Movement impairments in persons with LBP are not limited to tasks requiring an APA. Stabilization and movement system impairment-based treatments for LBP do not ameliorate and may exacerbate APA impairments (ie, excessive force application and increased post-movement trunk muscle activation).

However, an analysis of activation sequences within different levels of the trunk musculature has yet to be conducted. This study identified the activation sequences characteristic of the trunk musculature during upright standing and range-of-motion tasks. Surface electromyography was recorded for eight trunk muscles bilaterally during trunk range-of-motion movement tasks in 30 participants. Cross-correlation was performed on 48 pairings of muscles, consisting of one lower- and one mid-level muscle, or one mid-level and one upper muscle. Time lags of the maximum cross-correlation coefficient were extracted and defined as a top-down or bottom-up activation sequence, or similar activation timing. Pairings that demonstrated a specific activation sequence in 50% or more of participants were then identified. Similar activation timing was consistently identified between muscle pairings for upright standing. Top-down sequences and similar timing were identified for abdominal - mid-level pairings in maximum flexion and slumped standing, respectively, while both tasks were characterized by bottom-up sequences when considering the lumbar and lower-thoracic erector spinae. Sequences were more variable across muscle pairings for lateral bend and axial twist tasks. These results provide insight into the synergy of the trunk musculature for movements in the three planes of motion. These findings can be used for comparison to low back pain populations, as altered activation sequences in these individuals may contribute to maladaptive loading patterns and consequently the development or exacerbation of low back pain.

Type: This was a systematic review. Literature Survey: ELSEVIER, Pro Quest, PubMed, Google scholar and MEDLINE electronic databases were explored for the period from the earliest researchable time to August 2014. Articles investigating patients with chronic LBP and analyzing trunk muscles with surface electromyography (EMG) during walking were included. Methodology: All studies had a case-control design. Characteristics of the LBP patients, sample size, studied muscles and EMG parameters, and gait condition and velocity were investigated. Studies were rated as "A" to "E" (5 grades defined) based on study design and performance. Results: Multifidus (MF), erector spinae (ES), external oblique (EO), and rectus abdominus (RA) muscle activity level were found to be increased in LBP subjects in comparison with controls. ES activity in subjects with LBP was found not to be as adaptive to walking velocity alterations as in healthy controls. Conclusions: Individuals with chronic LBP exhibit higher global trunk muscle activity. However, the activation pattern appears to vary depending on subphases of gait. It seems that increased walking velocity challenges the stability of the spine and the control system increases muscular activation and variability level to cope with this problem. Further standardized studies with subtyped LBP cases are needed to clarify the controversial findings. Copyright © 2015 American Academy of Physical Medicine and Rehabilitation.

Twenty healthy volunteers participated in four sessions. An intervention was made by injection of either 0.2 ml of monosodium glutamate/isotonic saline (MSG/IS) (randomized) in either the masseter or TMJ (randomized). The participants were asked to hold and split a flat-faced placebo tablet with their anterior teeth, thirty times each at baseline, during intervention and post-intervention. Pain was measured using a 0-10 visual analog scale. The force applied by the teeth to "hold" and "split" the tablet along with the corresponding electromyographic (EMG) activity of the jaw muscles and subject-based reports on perception of pain was recorded. The data analysis included a three-way analysis of variance model. The peak pain intensity was significantly higher during the painful MSG injections in the TMJ (6.1 +/- 0.4) than the injections in masseter muscle (5.5 +/- 0.5) (P = 0.037). Variability of hold force was significantly smaller during the MSG injection than IS injection in the masseter (P = 0.024). However, there was no significant effect of intervention on the variability of split force during the masseter injections (P = 0.769) and variability of hold and split force during the TMJ injections (P = 0.481, P = 0.545). The variability of the EMG activity of the jaw muscles did not show significant effects of intervention. Subject-based reports revealed that pain did not interfere in the ability to hold the tablet in 57.9 and 78.9 %, and the ability to split the tablet in 78.9 and 68.4 %, of the participants, respectively, during painful masseter and TMJ injections. Hence, experimental pain in the masseter muscle or TMJ did not have any robust effect in terms of bigger variability of bite force and jaw muscle activity, during repeated splitting of food morsels.

BACKGROUND: Lumbar muscle fatigue is a common occurrence among workers. Alteration in motor coordination is one consequence of muscular fatigue. According to previous studies, CLBP subjects use their back and abdominal muscles in different ways, but questions remain about abdominal muscle responses to back muscle fatigue in CLBP patients. METHOD: Thirteen CLBP patients and 15 healthy subjects participated in this study. The thickness of abdominal muscles-including transverse abdominis (TrA), internal oblique abdominis (IO), and external oblique abdominis (EO) muscles-was measured in standing position with and without axial loads before and after a lifting fatigue task. RESULTS: The results reveal a significant difference for the main effects of group on percentage of change in TrA thickness (F = 8.9, p = .004). Percentage of change in thickness of TrA was 10% greater in the CLBP group. Although IO thickness displayed greater percentage of change in the CLBP group, the difference between groups was not significant. CONCLUSION: Abdominal muscle behavior changes with back-muscle fatigue in both healthy and CLBP subjects, but responses were more exaggerated in CLBP patients. APPLICATION: Ultrasound imaging technique can provide critical information about the effect of fatigue on spinal muscle activation and consequently about the stability of the spine. As a more applicable and easy technique, ergonomists can use ultrasound imaging in musculoskeletal system assessment in worker populations in future studies.

Dual-tasking, or performing two or more activities at the same time, is a skill we often perform during these daily activities. Researchers have already investigated the effect of cognitive dualtasks on postural control of healthy subjects and low back pain patients. However, daily we perform many motor dual-tasks. According to the authors' knowledge, there has been no study that investigated both, cognitive and motor dual-tasks, in a low back pain population. Purpose: The aim of this study was to investigate the influence of cognitive dual-tasks versus motor dual-tasks on motor control and muscle activity of pelvis and trunk in low back pain patients compared to healthy control subjects. Methods: As basic task the participants performed a Waiters Bow, a standardised active trunk flexion movement test. This basic task was combined with two different cognitive tasks (= cognitive dual-tasks) and with a motor task (= motor dual-task). The Zebris, a 3-dimensional motion analysis system, measured the movements of pelvis and trunk. The ME 6000 registrated the activity of the M. Multifidus, M. Latissimus Dorsi, M. Obliquus internus and the M. Obliquus externus. Results: The control group (n = 16) moved significantly less with their thorax (p<0.001), significantly more (p = 0.020) with their pelvis and showed a significant increase of M. Multifidus activity (p = 0.020) during the motor dual-task when compared to the basic task or the cognitive dual-tasks. While the low back pain group (n = 16), presented a similar but non significantly different trend. Conclusions: The control group significantly changed their movement strategy when performing the motor dual-task compared to the basic or cognitive dual-tasks, in contrast with the low back pain group who did not change their movement strategy significantly. Implications: The present study showed that chronic low back pain patients did not adapt their movement strategy during a motor dualtask in contrast with the healthy subjects who moved significantly different. Lack of neuromotor adaptation is typical in low back pain patients. It is important to keep in mind that a sudden low back pain onset is commonly reported during trunk flexion, like the Waiters Bow movement. Further research, about trunk flexion and dualtasking, should investigate the mechanism behind the deficiency of low back pain patients to adapt their movement strategy, given that this could lead to an appropriate treatment.

The spino-trigeminal system supports the hypothesis that the presence of pain in one of these two regions could affect the motor behaviour of the other. While experimental evidences showed that patients with temporomandibular disorders display electromyographic alterations of the neck flexor and extensor muscle (Armijo-Olivo and Magee, 2013), alterations of the jaw muscles in patients with neck pain have not been investigated yet. Objectives: To investigate precision, accuracy and electromyographic activity of jaw muscles contraction during a unilateral bite task in subjects with neck pain. Methods: Ten subjects with chronic neck pain and an age and gender-matched sample of healthy individuals volunteered for this study. The maximal voluntary bite force (MVC) was measured with a flexible force transducer positioned between the first molar teeth and used to set up a biting task requiring the subjects to match 4 targets (10, 30, 50 and 70%MVC) displayed on a computer monitor. Electromyographic (EMG) signals of the masseter and anterior temporalis muscles were recorded bilaterally. The subject's force performance was measured using error indices from the reference target like the Mean Distance (MD), Offset Error (OE) and the Standard Deviation (SD) of the delivered force. The Root Mean Square (RMS) of the electromyogram was calculated to detect differences in muscular activity. Between-group differences of the force indices (MD, OE, SD) and EMG activity (RMS) were assessed through Kruskal-Wallis test significance level was set to 0.05. Results: There were no significant between-group differences in force production for MD (H =0.38, P=0.5), OE (H =1.81, P=0.2) and SD (H =0.26, P=0.6). A significant difference in electromyographic activity was however detected for the masseter muscle (H =7.19, P=0.007, please refer to Figure) but not for temporalis (H =3.82, P=0.05). Conclusions: This study demonstrates that patients with neck pain present higher masticatory muscle activity during a unilateral biting task. Our results support the strong functional relationship between temporomandibular and neck regions and invite to consider, also in clinical setting, the possibility that a disorder affecting one region can have consequences on the functionality of the other. In fact, even though the motor output was comparable between groups, subjects with neck pain displayed higher RMS activity of masseter muscle to deliver the same force.

Co-contraction of the bilateral trunk muscles is known to stabilize the lumbar spine by increasing the stiffness. In contract, reciprocal activations of these muscles could be efficient to mobilize the lumbar spine, causing a trunk axial rotation. This asymmetric activation was in fact observed for the transversus abdominis during the unilateral upper limb movement (Morris et al., 2012 Clin. Biomech.). On the other hand, the unilateral lower limb movement would require trunk stabilization rather than mobilization to keep the upper body stable while standing on one leg. However, it is still unclear if the trunk muscles would demonstrate bilateral or reciprocal activation patterns during lower limb movement. Purpose: The objective of this study was to investigate whether the bilateral lumbar multifidus (MF), gluteus maximus (GM), and semitendinous (ST) would demonstrate bilateral or reciprocal activation during unilateral prone hip extension (PHE). Methods: Fifteen young male subjects (age: 21.5+/-2.7 yrs; height: 168.2+/-5.3 cm; weight: 67.1+/-8.7 kg) participated in this study. Subjects were laid prone on the bed and were instructed to perform unilateral PHE at their natural speed. Five trials for each dominant and non-dominant leg were performed in a random order. Surface electromyography (EMG) was recorded bilaterally from the MF, GM, and ST on both sides at 1000 Hz. The EMG signals were rectified and low-pass filtered at 10 Hz. Muscle onset latency was identified as the instant when the EMG signal exceeded two standard deviations of the baseline mean. The onset latencies were averaged for the five trials. Results: During PHE with the dominant leg, the onset of the MF activity on the ipsilateral side was followed by that on the contralateral side (p < 0.05). However, during PHE with the non-dominant leg, no significant difference was found in the onset latency between the bilateral MF. The onset of the GM was significantly later than that of the ST only during PHE with the non-dominant leg (p < 0.05). This sequential onset of the GM and ST was previously observed in the low back pain patients (Vogt L et al., 2003, Manual Therapy). Conclusion(s): The MF muscle demonstrated different activation patterns depending on the legs being used for PHE. The ipsilateral MF activation was followed by the contralateral activation when PHE was performed with the dominant leg, while the simultaneous activation of the bilateral MF occurred when performed with the non-dominant leg. Implications: In general, the trunk muscles are known to serve two purposes: 1) coordination between trunk and limb movements, and 2) trunk stabilization. During lower limb movement on the dominant side, the sequential MF activities could facilitate the coordination of limb-trunk movement rather than the stabilization of the trunk.

However, little evidence had been shown to examine the influence on the muscle activation patterns for the neck and upper limbs with this intervention. Purpose: To investigate the muscle activities of the neck and upper limb while performing typing tasks with and without maintaining the scapula in a retracted position, known as SPC, in healthy and neck pain subjects. Methods: Twenty four healthy subjects (mean age = 28.0+/-4.5) who were symptom-free and fifteen neck pain subjects (mean age = 29.8+/-1.7) participated in this study. Participants were instructed on how to perform and maintain the SPC action before the actual tests. Surface electromyography (EMG) was recorded while the all subjects performed two sessions of 5-min typing task with and without SPC respectively. The muscles examined were the right upper trapezius (UT), lower trapezius (LT), anterior deltoid (AD), biceps (BR), triceps (TR), flexor carpi radialis (FCR) and extensor carpi radialis (ECR). A three-dimensional motion sensor system was used to monitor the scapular position during typing. Results: The results revealed a significantly lower median muscle activity of UT and AD (p < 0.01) and higher median activity of LT (p < 0.01) when SPC was performed in each group. It was observed that the scapular postural angle in the transverse plane representing scapular retraction was significantly increased in the SPC condition (-23.94degree +/-6.83 in NSPC; -8.46degree +/-7.18in SPC; with a difference of 15.48degree +/-2.28) in the healthy group. When these muscle activities were compared between two groups, it was found that the effect on reducing UT muscle activity during SPC in the neck pain group was significantly less compared to the healthy control group (p < 0.05). Conclusion(s): This study demonstrated that maintaining the scapula in a retracted position while performing computer typing task was associated with a significant relaxation of the UT and increased activation of LT and this effect was more apparent in healthy subjects. This result suggests that the symptomatic persons need to undergo substantial training especially involving functional task simulation in order to achieve the therapeutic effects. In addition, it is also important to examine the upper limb muscle coordination which may need to be included as part of the motor control training. Implications: Motor control training involving scapular positional control should be conducted in situations involving functional tasks when managing patients with neck and shoulder disorders.

Results or Clinical Course: A 92-year-old man with a past medical history of coronary artery disease, hypertension, diabetes mellitus, prostate and colon cancer, and transient ischemic attack presented with left hemiparesis and MRI evidence of right middle cerebral artery acute ischemic stroke. This lesion was attributed to an atrial thrombus found on echocardiogram. The patient was transitioned from a heparin drip to warfarin with an enoxaparin bridge 80mg every 12 hours, in addition to his home dose of 81mg Aspirin. He was admitted to acute inpatient rehabilitation with primarily deficits in dynamic balance, coordination, and vision, as his strength was measured as an equal 5/5 in all four extremities. On rehab day two he began to complain of left groin pain interfering with ambulation. Examination revealed tenderness to palpation over the left femur at the insertion of the iliopsoas. Strength of left lower extremity was intact distally, while hip flexion strength and range of motion were limited due to pain, measured as 2/5. At this time the patient's INR was 1.3 and his hemoglobin had dropped from 12.0 on admission to 8.9. A CT scan revealed a hematoma in left iliopsoas muscle extending from the pelvis to its attachment on femur below the lesser trochanter, and further anticoagulation was held. His groin pain and hip flexor weakness gradually improved over the next 5 days, hemoglobin returned to 10.0 and warfarin was restarted without an enoxaparin bridge. Discussion: While it is prudent to first consider stroke extension, hemorrhagic transformation, or new lesion in a patient exhibiting new weakness after an acute stroke, other peripheral causes of weakness must be considered as well. Retroperitoneal or iliopsoas muscle hematomas are likely causes of lower extremity weakness in patients with increased risk of bleeding. Conclusion: Large hematomas can place pressure on the lumbosacral plexus or on the femoral nerve in iliopsoas hematomas leading to neurapraxia. Mechanical fullness alone can also lead to weakness and pain without neurologic compromise, as seen in this case. Initial workup should include CT or ultrasound imaging and monitoring of hemoglobin. While, most cases are self limited, persistent weakness should be evaluated by electromyography.

These common conditions include lumbar and cervical facet syndrome and sacroiliac (SI) joint dysfunction. To use RFA effectively, practitioners must understand the electrophysiological principles and technical aspects to successfully treat the targeted structure and limit the risk of complications. In addition, practitioners should have an in-depth understanding of relevant anatomy and appropriate patient selection to improve procedural outcomes. General Principles The ability to ablate specific tissues while limiting destruction to nontargeted tissues is dependent on factors that influence energy delivery and local physiological tissue characteristics. The bioheat equation describes coagulation necrosis.1 Bioheat equation Coagulation necrosis = (heat generated x local tissue interactions) - heat lost In a simplified thermal RFA system, three primary factors determine heat generation and the size of the lesion: distance from the active tip, radiofrequency current density, and duration of application of the radiofrequency current.2 Monopolar and Bipolar Thermal RFA Thermal RFA involves the use of high-frequency alternating current and results in irreversible cellular damage from focal high temperature tissue heating.3 Temperature-controlled RFA systems are primarily employed in interventional pain medicine. For monopolar RFA, the high-frequency alternating current flows from the uninsulated active tip into the tissue. The alternating current produces frictional heating in the tissue surrounding the electrode.2 For conventional RFA, the time of lesioning, tip size, and set temperature all influence the final lesion size. With monopolar RFA, lesions are in the shape of a prolate spheroid with coagulation occurring primarily in the radial direction perpendicular to the long axis of the electrode. Minimal lesioning occurs distal to the tip. Therefore, for monopolar RFA, the cannula should be placed with its shaft parallel to the target nerve.4,5 In bipolar RFA, a passive electrode replaces the grounding pad with the goal of focusing the electrical current between the electrodes. A 3-dimensional Cartesian coordinate system describes a bipolar lesion. Bipolar RFA is employed when a larger lesion is required and has been used for SI RFA of the lateral branches.6-11 When performing bipolar RFA, it is important to understand specific configuration parameters that will influence lesion development including: 1) active tip size and length, 2) fluid preinjection composition, technique and volume, 3) interelectrode distance, 4) lesion time, 5) tip configuration, and 6) tip temperature.7,9 One parameter that is of crucial importance is the set interelectrode distance (IED). The goal should be to choose an IED that will allow for the ablation of the desired area and minimize destruction to nontargeted structures. In addition, the IED should be set to limit hourglass lesioning. The maximum allowed IED will depend on multiple configuration parameters including the size of the active tip, lesioning time, and composition of the preinjected fluid.6,7,9 Cooled RFA Recently, cooled RFA has been used for the treatment of SI joint dysfunction. 10-12 Compared with traditional thermal RFA, cooled RFA results in significant lesion development distal to the tip of the RFA cannula. Lesioning distal to the tip is advantageous in certain anatomical areas, such as the SI joint, where perpendicular placement of the cannula is often required. In cooled RFA, an electrode is utilized that allows for continuous internal cooling of the tip with a perfusate.13 Methods to Modulate the Local Tissue Environment to Increase Lesion Size In the quest to enlarge the coagulation zone, methods to modulate the local tissue environment surrounding the RFA cannula to allow for greater energy deposition have been investigated.9,13-15 The nerves innervating the facet joints have a diameter of less than 2 mm and anatomical variability is common.16-18 Therefore, the development of controlled and defined larger lesions may assist with lesioning structures that are small and have variable courses, with the goal of limiting technical failures. The chemical composition of the preinjected fluid has been shown to alter lesion size and development in both monopolar and bipolar RFA setups. Increasing the sodium chloride concentration of the preinjected fluid has been shown to significantly increase power output and lesion size.15,19 Studies to date have been in ex vivo models and further research is warranted. Lumbar Medial Branch RFA for Facet Joint Mediated Pain The therapeutic efficacy of lumbar medial branch RFA has been evaluated in observational and randomized controlled trials (RCTs). Of the six RCTs, three had technical flaws in both patient selection and surgical technique, which hinders interpretation of the results.20-22 The other three studies had definitively positive results for RFA.23-25 The study by Nath et al.25 demonstrated that the active treatment groups had statistically significant improvement in back/leg pain and back/hip movement at six months. Improvement was also seen in quality-of-life scores and in reduced use of analgesics. No significant complications were reported. Two observational studies also demonstrated that RFA is effective.26,27 Dreyfuss et al.,27 in a study of 15 patients with a diagnosis of lumbar facet syndrome made with diagnostic controlled medial branch blocks, demonstrated 90% pain relief in 60% of treated individuals at 12 months. At least 60% pain reduction was seen in 87% of the patients at 12 months. Gofeld et al.26, in a large clinical audit of 209 patients (179 of whom completed the study; 35 were lost to follow-up), reported that 68.4% had good (>50% pain relief ) to excellent (>80% pain relief ) results lasting from 6 to 24 months. Cervical Medial Branch RFA for Facet Joint Mediated Pain A systematic review evaluating a randomized controlled trial and four observational studies provides strong evidence that cervical medial branch RFA is a successful treatment for chronic neck pain.28 Lord et al.,29 in a randomized double-blind trial, compared RFA to sham denervation in patients with cervical facet pain confirmed with double-blind, placebo-controlled local anesthetic blocks. RFA denervation was found to be superior to the sham procedure, and the median time that elapsed before pain returned to at least 50% of the preoperative level in the RFA group was 263 days. SI Joint RFA Several RFA techniques that target the posterior innervation of the joint have been developed to treat SI joint pain. One of the associated challenges with SI joint RFA includes an incomplete understanding of the innervation of the joint. Furthermore, the innervation of the SI joint consists of small nerves with diameters ranging from 0.292 to 0.997 mm that are difficult to locate with sensory stimulation and have variable anatomic courses in relation to bony anatomy.30 RFA techniques utilized include bipolar intraarticular RFA, bipolarlateral branch RFA, cooled RFAof the lateral branches, and sensory stimulation guided SI joint RFA.7,8,10,11,31,32 Recently the employment of cooled RFA has shown promise in the treatment of SI pain. In a randomized placebo-controlled study examining lateral branch radiofrequency denervation with cooled RFA, Cohen et al.10 reported that 57% of patients obtained 50% or greater pain relief at 6 months. Cooled RFA creates wide diameter lesions that may increase the ability to target areas of nociceptive input. The study by Cohen also demonstrated functional improvements. In individuals with successful pain relief, the median duration of relief was 7.9 +/- 4.7 months. Patel et al.11 studied the efficacy of lateral branch cooled RFA in a randomized placebo-controlled study. Significant improvements in pain, disability, physical function, and quality of life at 3-month follow-up were demonstrated with cooled RFA compared with placebo. Complications: Although radiofrequency treatment can be associated with both minor and major complications, there are limited data documenting the occurrence of these events.33,34 Following RFA, a temporary exacerbation of pain secondary to an inflammatory response will often occur and can last several days to two weeks. Some patients may also experience transient dysesthesias of the skin over the operative area, arising from partial denervation of the lateral branch of the posterior primary ramus. These transient dysesthesias occur more frequently with cervical medial branch RFA. Another concern with RFA is the morphological changes that may occur in the spine after lesioning the medial branches. In the lumbar spine, in addition to providing sensory innervation to the lumbar facet joint, the medial branch also provides innervation to the multifidus muscle. The multifidus muscle plays an important role in segmental spine stabilization and postural stability. Following RFA, electromyography has demonstrated denervation of the multifidus muscle.35 Other complications that may occur following cervical medial branch and third occipital nerve RFA include ataxia and spatial disorientation.36 These complications are more common with cervical medial branch RFA of the upper cervical levels, especially the third occipital nerve, and are usually mild and self-limiting. One of the most feared complications is damage to surrounding nontargeted spinal nerves. Methods to prevent this complication include precise anatomical placement of the RFA cannula through fluoroscopic guidance, physiological testing, and a detailed understanding of lesion dimensions.

Here, we report a novel SEPT9 mutation and the variability of expression of hereditary neuralgic amyotrophy (HNA) in a multi-generational family. Methods: Case Series Results: The proband, a 54-year-old man presented with right arm weakness preceded by pain approximately 2 weeks prior. He reported that many of his family members had had a similar episode at variable ages, and with varying degrees of weakness. Some of them had experienced sequential and/or recurrent asymmetric weakness in the upper extremities. Neurological examination revealed normal cranial nerves, scapular winging, asymmetric proximal weakness, hyporeflexia and normal lower extremity examination. MRI of brachial plexus revealed enhancement of the T1 nerve root. EMG/ NCS revealed bilateral brachial plexopathy. Gene testing revealed a novel aberration in the SEPT9 gene (38 Kb duplication with a proximal breakpoint in the exon 2 of SEPT9). Clinical evaluation and medical history of family members revealed varying ages on onset, different patterns of muscle involvement and recurrence and hypotelorism in all the affected members. Conclusion: We report a novel SEPT9 mutation in a multigenerational family with HNA and its clinical variability. Hypotelorism and recurrent painful brachial plexopathy seem to be invariant features associated with this novel mutation.

Another objective was to assess operator variability among electromyographers from different specialties. BACKGROUND: There are no such studies in literature that address the yield of EDX and operator variability specifically for above indication. METHOD: This was a retrospective chart review of EDX studies, which were done to evaluate for CR, in patients with above symptom and were done at VA Medical Center and UBMD neurology department. After IRB approval, we reviewed EDX reports of 1925 patients from 01/01/ 2002 to 12/31/2012 who were assigned ICD codes for cervical radiculopathy and had neck and/or upper extremity pain as chief complaint. There were 660 eligible patients, and data were collected for patients' age, gender, symptoms, major neurological findings, specialties of electromyographer, nerve conductions studies (NCS), EMG and MRI abnormalities (if available). "Chi" square and "t" tests were used through SPSS as needed. RESULTS: EDX studies revealed CR in 68.8 [percnt] of eligible patients. Chances of reporting a positive study were significantly higher if EDX was done by physiatrist (74.9[percnt]) compared to if done by neurologists (51.5[percnt]) for same indication. As expected percentage of radicular pain and other definitive neurological findings of radiculopathy were significantly higher in electrodiagnostically confirmed CR group and were present in 54.7[percnt] and 35.2[percnt] respectively. CONCLUSION: The diagnostic yield of EDX in our study was slightly higher than reported in the past. We found significant operator variability among electromyographers from different specialties. This is the first study to evaluate differences in diagnostic yields of EDX by various electromyographers for similar indication, and will help us to better understand role of EDX in CR that will impact referral patterns.

Methods: Functional anorectal pain patients between 2010 to 2013 were assessed in a tertiary referral center. Patients fulfilled Pain Visual Analog Scale(VAS, 0-10 point), sEMG Glazer protocol evaluation and SF-36 scales before and after treatment. Biofeedback only group (BF): 3 phases training day session outpatient by sEMG biofeedback system (anal-plug electrode, Thought Technology Ltd., Canada). Phase 1: Electric stimulation (10-second squeezing and 10- second resting intervals as 20KHz or 40KHz biphasic modulations, 5min). Phase 2: EMG-triggered stimulation (5 min). Phase 3: Kegel maneuver (20 min). 20 sessions requested. Acupuncture combined with biofeedback group (ACU+BF): Acupoints of bilateral BL33, BL34 pierced 75 mm deep into the sacral foramen with electrical stimulation, bilateral BL18, BL23, BL25 and Du20 as usual. 30 minutes once a day as a session outpatient. Combined with biofeedback as same protocol as BF group in a same treatment day. 20 sessions requested. 6 months telephone flow up. Results: One hundred forty six patients, 101 female, with a median age of 49.3 years were studied retrospectively. 135 Chronic proctalgia and 11 proctalgia fugax patients enrolled. 73 (50%) patients has moderate(4-6 point)) and 60 (42.4%) has severe (7-10 point) pain, occurred in daytime(45.7%), tenesmus & dull (56.5%), with pelvic floor dyssynergic (20%) and pelvic floor relaxation (24%) of defecation disorder and fecal incontinence (7.3%), 35.6% patients had psychological disturbance. BF group and ACU+BF group enrolled 71 and 75 patients respectively. Two groups has no difference in baseline. Compared in VAS Pain Scale: BF group VS ACU+BF group before (6.30+/-1.98 vs 6.43+/-1.92) and after(3.55+/-1.94 vs 2.25+/-1.38, P<0.05) treatment. sEMG evaluation: Both groups improved in resting, flick contraction, tonic contraction amplitude and muscle coefficient variability respectively (P<0.01) after treatment. SF-36 scale: Before intervention both groups showed the poor quality of life in 7 dimensions (except Social Functioning (P<0.05), ACU+BF group showed better result in 2 dimensions (General Health and Mental Health). Success rate: BF (n=71) vs ACU+BF (n=75), pain free patients was 9 vs 15, 50% improved patients was 41 vs 42, no change patients was 21 vs 18. The efficacy was 70.4% vs75.1% (P<0.01). 6 months follow up was 73.2% vs 67.5%(P<0.01). Conclusions: Acupuncture combined with biofeedback had better short term efficacy than biofeedback only in symptom release and quality of life of general health and mental health. sEMG assessment was a promising evaluation. Prospective randomized trials will be required (Figure Presented).

This type of compensatory motion may affect bilateral muscle function and loading of the lower extremity joints, and thereby impact risk of developing multi-articular OA. Unloading valgus knee braces are frequently prescribed for symptomatic relief for individuals with uni-compartmental knee OA. However, little is known about their potential effect on the mechanics of other lower extremity joints, or about their influence on hip abductor muscles that may contribute to trunk sway. Furthermore, most studies have focused on an older population while it is the <60 years who possibly stand to gain the most from conservative therapy. The purpose of this study was therefore to assess frontal plane hip and trunk biomechanics and hip muscle function in a relatively young, active OA patient population and examine the effects of an unloading brace (UnloaderOne) thereon. Methods: Seventeen male patients (age 40-60 years) with symptomatic medial knee OA and confirmed Kellgren-Lawrence grade II or III radiographic scores were recruited for the study. All had received a prescription for an unloading brace. Fourteen asymptomatic males were recruited as controls (CTRL). Conventional gait analysis was performed to assess kinematic and kinetic patterns during overground walking. OA participants were assessed both with and without the brace during an initial assessment within 48 hours of brace fitting and again 4 weeks later. Isometric hip abductor strength was measured and activation levels of gluteus medius (Gmed) and tensor fasciae latae (TFL) muscles were monitored with surface electromyography (EMG). Knee pain and function were assessed with questionnaires (KOOS and KOSADLS). Due to the great variability in the response to the brace over the 4 week period, as measured by the self-reported knee outcome questionnaires, OA participants were stratified into responders (R) and nonresponders (NR) according to OARSI - OMERACT criteria for clinical trials. Alpha was set at 0.05 for statistical analyses, which included correlations, t-tests and repeated measures analysis of variance. Results: No group differences were found for age, BMI, or normalized hip abductor muscle strength. Overall, self-report scores of OA participants improved (p<0.05), but great variability was seen in the response. At baseline the Rs had lower scores than the NRs on pain, symptoms and ACL subscales of the KOOS questionnaire (p<0.05), after 4 weeks brace treatment the Rs had improved more than NRs on all KOOS subscales (p<0.05). OA participants demonstrated less trunk lean to stance side at initial contact (IC) (p=0.015), and a delay in transition of trunk lean from stance to contralateral side, compared to CTRLs. Rs also had greater frontal plane trunk excursion during stance phase (p=0.034) than CTRLs and NRs. An overall increase in trunk lean at IC (p<0.05) and a decrease in excursion (p<0.01) was found at follow up. No intergroup or interlimb differences were found for hip adduction moments or angles and no changes were detected over time for those parameters. No significant group or interlimb differences were found for peak muscle activation levels of Gmed at baseline but peak activation levels of TFL were significantly higher for R than CTRLs (p<0.001) and NRs (p<0.001). Rs demonstrated an increase in Gmed peak muscle activation level when wearing the brace (p<0.01). Conclusions: Overall, self-report scores improved after a 4 week brace treatment, while frontal plane angles or moments at the hip were not affected. Variability in treatment response, despite significant mean improvement, is a reality that is clinically important to acknowledge. Muscle activation patterns of the hip abductors differed between CTRLs and OA participants, and there also appeared to be differences in muscle activation between those who responded to unloader bracing treatment after 4 weeks and those who didn't. Further studies to identify clinical baseline factors that could predict which patients are likely to benefit from using an unloading brace seem to be justified. The differences involving the trunk involved both excursion and timing of its lateral shift and, although small, seem to represent a compensatory mechanism which the brace appeared to affect over time. The significance of this, with respect to knee joint loading or progression of multi-articular OA is, however, unclear and further studies are warranted.

Hermedical history was notable for a transient ischemic attack, which prompted initiation of simvastatin four years earlier. She had no family history of neuromuscular disease. Physical exam demonstrated intact upper extremity strength but reduced strength (4/5) in the proximal lower extremity muscle groups bilaterally. She was noted to rise slowly from a chair without use of her arms. Neurologic exam was otherwise unremarkable. Laboratory work-up was normal except for a creatine kinase (CK) level of 1116 U per liter (normal range 23-143 U per liter). Her muscle weakness and CK elevation were attributed to statin myopathy, and simvastatin was discontinued. Over the next 3 months, the CK level decreased but never normalized. The lower extremity muscle pain and weakness persisted as well. Muscle biopsy was performed and demonstrated absent myophosphorylase activity. Additional history revealed subjective muscle weakness and reduced exercise tolerance dating back to childhood. Surprisingly, there were no clinical episodes of rhabdomyolysis, despite participation in at least one 10-km road race. Muscle symptoms worsened after initiation of simvastatin, but the patient attributed this to aging and deferred seeking medical attention until symptoms became severe. Based on her lifelong muscle weakness, difficulty tolerating exercise, and absent myophosphorylase staining on biopsy, a diagnosis of McArdle disease (myophosphorylase deficiency) was made. The patient and her son received counseling on the management and genetic implications of this diagnosis. DISCUSSION: Statins are near-ubiquitous medications with myopathic side effects ranging from myalgia to rhabdomyolysis. The reported frequency of statin-associated muscle events is 1-5 % in clinical trials and 11-29 % in observational cohorts; the difference is attributed in part to patient selection in the trials. The onset of muscle symptoms typically occurs within weeks to months of statin initiation but can occur at any point in the treatment course. CK elevation, if present, can range from >3-fold to >50- fold greater than untreated baseline values. Time to recovery from statin myopathy following statin withdrawal likewise can be variable with respect to both symptom resolution and normalization of CK. Numerous conditions can increase the risk for statin-induced muscle toxicity, including age, gender, co-morbid medical conditions, drug-drug interactions, and genetic variants. In patients with previously undiagnosed metabolic myopathy, statins may precipitate or worsen neuromuscular symptoms, as described in the case above. There are several case reports of statin therapy unmasking not only McArdle disease but also CPT II deficiency, myoadenylate deaminase deficiency, and mitochondrial diseases. One cross-sectional study of patients with drug-induced myopathies found a higher prevalence of hereditary metabolic muscle disorders (both homozygote and carrier states) than would be expected in the general population. Another retrospective study of patients who developed chronic muscle diseases after age 50 observed a greater than expected frequency of prior exposure to statins. The precise mechanism by which statins trigger clinical expression of pre-existing myopathy is unknown, but it is postulated that statin effects on energy metabolism couple with genetic susceptibility to produce muscle symptoms in these high-risk patients. In practice, it can be difficult to distinguish between pure medication-related myotoxicity and latent or subtle muscle disease that becomes clinically manifest after statin administration. Regardless of etiology, it is appropriate to stop a statin in the setting of intolerable symptoms and/or significant CK elevations (>10 times the upper limit of normal). Current literature suggests that patients with muscle symptoms (particularly weakness) and elevated CK levels (>3 times the upper limit of normal) that persist 1-3 months after statin discontinuation should receive diagnostic evaluation for underlying muscle disease. Electromyography can be a useful screening test to determine if muscle biopsy is needed, especially in patients with asymptomatic CK elevations. CK measurement prior to onset of statin therapy, while not necessary in all patients, is recommended in those with baseline muscle complaints. This may lead to earlier identification of underlying primary muscle disease and help mitigate diagnostic uncertainty when a new statin user develops muscle symptoms.

Compared to similar open surgeries, laparoscopic procedures are limited by the fulcrum effect, the general lack of articulating instruments, and the adoption of a less mobile posture. On the other hand, the use of laparoscopy allows the surgeon to operate in an upright position without having to lean over the site of incision. Subjective studies of surgeons who perform laparoscopy report a near universal incidence of chronic musculoskeletal pain and injury. To date, the ergonomic stress of laparoscopy compared to open surgery has not been objectively measured. The purpose of this study is to quantify and compare the ergonomic stress experienced by a surgeon while performing open versus laparoscopic portions of a procedure. We hypothesize that a surgeon will experience greater ergonomic strain when performing laparoscopic surgery than when performing open surgery. Methods and Procedures: We designed a prospective study to measure upper body muscle activation during the laparoscopic and open portions of sigmoid colectomies in a single surgeon. A sample of five cases were recorded over a two-month time span (June to July 2014). Each case contained significant portions of laparoscopic and open surgery (average duration of laparoscopic surgery was 89.7 min; average duration of open surgery was 84.1 min). Using a wireless electromyography (EMG) system, we obtained whole-case EMG tracings from the subject's left and right biceps, triceps, deltoid, and trapezius muscles. After normalization to a maximum voltage of contraction (MVC), these EMG tracings were used to calculate average muscle activation during the open and laparoscopic segments of each procedure. Paired Student's T-test was used to compare the average muscle activation between the two groups (*p<0.05 considered statistically significant). Results: Significant reductions of mean muscle activation in laparoscopic compared to open procedures were noted for the left triceps (34.7 %), left deltoid (45.8 %), left trapezius (53.6 %), right triceps (37.3 %) and right trapezius (54.0 %). There were no statistically significant changes of mean muscle activations in the left biceps, right biceps and right deltoid between open and laparoscopic portions of the procedures. Conclusion: Contrary to our hypothesis, the laparoscopic approach provided ergonomic benefit in several upper body muscle groups compared to the open approach. This may be due to the greater reach of laparoscopic instruments and camera in the lower abdomen/pelvis. Patient body habitus may also have less of an effect in the laparoscopic compared to open approach. Performing the study in a single subject allowed for control of inter-surgeon variability. Analysis of paired data of open and laparoscopic portions within individual procedures helped control for variability in patient factors (e.g., body habitus, degree of difficulty). Future studies with multiple subjects and different types of procedures are planned to further investigate these findings. (Figure Presented).

The second aim of the study was to assess if the mechanical technique is an important determinant of the subsequent reflex response. Materials and methods: In this study, twelve neurologists elicited the Babinski reflex five times on the same foot of the same participant using a special reflex hammer which recorded the force and duration of the stroke. Hallux movement, tibialis anterior maximum EMG amplitude and pain felt by the participant for each stroke were recorded. Results: A large inter- and intra-applicator variability was shown amongst the neurologists. The change in hallux angle was significantly correlated with the duration of the stroke (R2=0.18, P<0.01), maximum (R2=0.14, P=0.01) and average (R2=0.17, P<0.01) force used to elicit the reflex. No correlations were shown between the hammer forces and duration and the maximum amplitude of the tibialis anterior. Significant correlations were shown between the pain score and the maximum (R2=0.15, P<0.01) and average (R2=0.17, P=0.001) force used to elicit the Babinski reflex. Conclusion: These results indicate that there was substantial variation when performing the Babinski reflex test within and between neurologists which could lead to differences in the resultant reflex and therefore may affect subsequent diagnoses.

Inadequate oxygen consumption and/or inadequate blood supply can influence the ability of the muscles to withstand fatigue. However, it remains unknown if oxygenation and hemodynamics are associated with early fatigue in muscles of WRMP patients. In the present study we applied near-infrared spectroscopy (NIRS) on the extensor carpi radialis (ECR) and trapezius (TD) muscles of patients with WRMP (n = 18) and healthy controls (n = 17). Our objective was to determine if there were group differences in endurance times for a low-level contraction of 15% maximal voluntary contraction (MVC) - sustained for 12-13 min, and to see if these differences were associated with differences in muscle oxygenation and hemodynamics. At baseline, oxygen saturation (StO2%) was similar between groups for the ECR, but StO2% was significantly lower for TD for the WRMP patients (76%) compared to controls (85%) (P<0.01). Also, baseline ECR blood flow was similar in the two groups. For both muscles there were a larger number of patients, compared to controls, that did not maintain the 15% MVC for the allotted time. Consequently, the endurance times were significantly shorter for the WRMP patients than controls (medians, ECR: 347 s vs. 582 s; TD: 430 s vs. 723 s respectively). Responses in StO2% during the contractions were not significantly different between groups for either muscle, i.e. no apparent difference in oxygen consumption. Overall, we interpret our findings to indicate that the early fatigue for our WRMP patients was not associated with muscle oxygenation and hemodynamics. © 2014 Elcadi et al.

The definition of pelvic pain itself often depends on the medical specialist evaluating the patient. Because there is variability among disorders associated with pelvic pain, patients may seek treatment for extended periods as various treatment options are attempted. Further, health care providers should recognize that there may not be a single source of dysfunction. This article discusses the musculoskeletal disorders of the pelvic girdle (structures within the bony pelvis) and their association with lumbar spine and hip disorders. © 2014 Elsevier Inc.

An additional aim was to explore associations between primary neck muscle endurance, myoelectric fatigability, and self-rated levels of fatigue, pain and subjective health measurements in patients with cervical radiculopathy. Methods: Muscle fatigue in the ventral and dorsal neck muscles was assessed in patients with cervical radiculopathy and in an asymptomatic group during an isometric neck muscle endurance test in prone and supine. 46 patients and 34 asymptomatic subjects participated. Surface electromyography signals were recorded from the sternocleidomastoid, cervical paraspinal muscles and upper and middle trapezius bilaterally during the endurance test. Subjective health measurements were assessed with questionnaires. Results: The results showed altered neck muscle endurance in several of the muscles investigated with greater negative median frequency slope, greater variability, side imbalance, lower endurance time and higher experience of fatigue among the cervical radiculopathy patients compared with healthy subjects. Endurance times were significantly lower in both prone and in supine positions between the patients compared to asymptomatic subjects. During the neck muscle endurance test, fatigues in the upper trapezius muscles during the prone test and in the sternocleidomastoid muscles during the supine test were of more importance than self-perceived pain, fatigue, disability and kinesiophobia in predicting neck muscle endurance (NME). Conclusion: NME testing in the primary neck muscles seems to be an important factor to take into consideration in rehabilitation. © 2013 Springer-Verlag.

Some even sense voluntary movements when viewing a mirror image of the intact limb superimposed onto the phantom limb. While delayed visual feedback of an action is known to reduce a sense of agency, the effect of delayed visual feedback on phantom motor sensation (i.e., sense of controlling a phantom limb) has not been examined. Using a video-projection system, we examined the effect of delayed visual feedback on phantom motor sensation in an upper-limb amputee (male; left upper-limb amputation). He was instructed to view mirrored video images of his intact hand clasping and unclasping during a phantom limb movement. He then rated the intensity of the phantom motor sensation. Three types of hand movement images were presented as follows: synchronous, asynchronous with a 250-ms delay, and asynchronous with a 500-ms delay. Results showed that phantom motor sensation decreased when the image was delayed by 250 and 500 ms. However, when we instructed the patient to adjust the phase of phantom limb movement to that of the image with a 500-ms delay, phantom motor sensation increased. There was also a positive correlation between intensity of phantom motor sensation and electromyographic (EMG) activity on deltoids at the patient's stump. These results suggest that phantom motor sensation and EMG activity on the stump depend on visuomotor synchrony and top-down effects. © 2014 Imaizumi, Asai, Kanayama, Kawamura and Koyama.

In recent years, the application of KinesioTaping (KT) has been proposed to enhance sensory inputs, decreasing spasticity by proprioception feedback and relieving abnormal muscle tension. Because no studies have examined KT-based techniques in SCI subjects, our goal was to analyze the effects of ankle joint KT on spasticity, balance, and gait. Materials and Methods: A randomized crossover case control design was used to compare the effects of KT and conventional nonelastic silk tape (ST) in 11 chronic SCI subjects, AIS level D, with soleus/gastrocnemius (S/G) muscle spasticity and balance and gait impairments. Treatment: 48 h of treatment with KT or ST was followed by 48 h with the other technique after 1 week. A single Y-strip of Cure© tape (KT) and ST was to the S and G muscles with 0% stretch. Before and 48 h after of application of KT and ST, clinical data on the range of motion (ROM), spasticity, clonus, pain, balance, and gait were collected. Stabilometric platform assessment of center of pressure (COP) movements; bidimensional gait analysis; and recording of electromyographic (EMG) activity of the S, G, and tibialis anterior and extensor hallucis lungus muscles were also performed. Results: Only KT had significant effects on spasticity (p < 0.05), clonus (p < 0.001) and COP movements (p < 0.05), kinematic gait parameters (p < 0.001), and EMG activity (p < 0.001). Comparison between ST and KT improvements pointed out significant differences as concerns ROM (p < 0.001), spasticity (p < 0.001), clonus (p < 0.001), pain (p < 0.001), COP parameters (p < 0.05), and most kinematic gait data (p < 0.05). Discussion: Short-term application of KT reduces spasticity and pain and improves balance and gait in chronic SCI subjects. Although these data are promising, they require confirmation in a larger cohort of patients. © 2014 Tamburella, Scivoletto and Molinari.

Methods A literature review was performed using Ovid Medline and Embase databases. A total of 306 abstracts and 78 full-text articles were reviewed. Forty-two articles were eligible for inclusion. Results Patients undergoing nerve-sacrifice neck dissections have greater disability and lower quality of life scores than those undergoing neck dissections with the least manipulation (ie, selective neck dissections). Shoulder impairments can still occur in patients undergoing selective neck dissections. Disability typically improves over time in patients undergoing nerve-sparing neck dissections. Conclusion There was significant variability in the literature in terms of the prevalence and recovery of shoulder morbidity after neck dissection. This variability may not just be related to surgical technique or rehabilitation, but also to study design, definitions, and the variability in disability questionnaires used.

Twenty-five healthy participants (13 men 12 women) performed a 30. min sitting task with 5 degrees inclination of the trunk. Surface electromyographic (EMG) signals were recorded bilaterally from the lumbar muscles with 2 high density surface EMG grids of 9. x. 14 electrodes. Median frequency (MDF) decrease, amplitude (RMS) increase and the rating of perceived exertion (RPE) were used as fatigue indices. Alternating activation and spatial and temporal variability were computed and relations with the fatigue indices were explored. During sitting, the mono- and bipolar RMS slightly increased while the MDF remained unchanged indicating no systematic muscle fatigue, although the average RPE increased from 6 to 13 on a scale ranging between 6 and 20. Higher frequency of alternating activation between the left and right side was associated with increased RPE (p= 0.03) and decreased MDF (p= 0.05). A tendency in the same direction was seen between increased spatial and temporal variation within the grids and increased RPE and decreased MDF. Present findings provide evidence for a relationship between variability in muscle activity and fatigue. © 2014 Elsevier Ltd.

The aim of this study was to investigate whether there are differences in the amplitude of the EMG signal of the BB muscle during fast and spin delivery, during the seven phases of both types of bowling and the kinesiological interpretation of the bowling arm for muscle contraction mechanisms during bowling. A group of 16 male amateur bowlers participated in this study, among them 8 fast bowlers (FB) and 8 spin bowlers (SB). The root mean square (EMGRMS), the average sEMG (EMGAVG), the maximum peak amplitude (EMGpeak), and the variability of the signal were calculated using the coefficient of variance (EMGCV) from the BB muscle of each bowler (FB and SB) during each bowling phase. The results demonstrate that, (i) the BB muscle is more active during FB than during SB, (ii) the point of ball release and follow-through generated higher signals than the other five movements during both bowling categories, (iii) the BB muscle variability is higher during SB compared with FB, (iv) four statistically significant differences (p < 0.05) found between the bowling phases in fast bowling and three in spin bowling, and (v) several arm mechanics occurred for muscle contraction. There are possible clinical significances from the outcomes; like, recurring dynamic contractions on BB muscle can facilitate to clarify the maximum occurrence of shoulder pain as well as biceps tendonitis those are medically observed in professional cricket bowlers, and treatment methods with specific injury prevention programmes should focus on the different bowling phases with the maximum muscle effect. Finally, these considerations will be of particular importance in assessing different physical therapy on bowler's muscle which can improve the ball delivery performance and stability of cricket bowlers. © 2014 Australasian College of Physical Scientists and Engineers in Medicine.

The aim of this study was to evaluate the variability of anticipatory postural adjustments (APAs) of trunk muscles in participants with low back pain (LBP). Material and Method: The study included 21 participants with recurrent non-specific LBP (15 men, 6 women) and 21 healthy volunteers. Standard deviation of electromyographic activity of the external oblique (EO), transverse abdominis/internal oblique (TrA/IO), and erector spinae (ES) muscles onset relative to deltoid muscle onset was recorded in 75 rapid arm flexions, and the correlation with the participants' avoidance belief (the FABQ score) and disability (the Roland-Morris Questionnaire score) was statistically analyzed. Results: participants with LBP exhibited less variability in timing of APAs of the TrA/IO muscle compared with the control group (P=0.047). The timing of APAs of the TrA/IO muscle was significantly correlated with the FABQ score (P=0.006). There was no significant correlation between this variable and disability (P=0.09). Decrease in variability of the timing of APA of the EO (P=0.45) and ES (P=0.6) muscles was not significant. Conclusion: The variability of the postural responses of participants with LBP decreased. Restoring variability in postural control responses might be a goal in rehabilitating these patients. © 2014 - IOS Press and the authors. All rights reserved.

While spinal manipulation (SM) is recommended for LBP treatment by recently published clinical guidelines, the underlying therapeutic mechanisms remain unclear. Spinal stiffness is routinely examined and used in clinical decisions for SM delivery. It has also been explored as a predictor for clinical improvement. Flexion-relaxation phenomenon has been demonstrated to distinguish between LBP and healthy populations. The primary objective of the current study is to collect preliminary estimates of variability and effect size for the associations of these two physiological measures with patient-centered outcomes in chronic LBP patients. Additionally biomechanical characteristics of SM delivery are collected with the intention to explore the potential dose-response relationship between SM and LBP improvement.Methods/Design: This is a prospective, observational study applying side-lying, high velocity, low amplitude SM as treatment for patients with LBP over a course of 6 weeks. Approximately 80 participants will be enrolled if they present with chronic LBP of 1, 2 or 3 in Quebec Task Force Classification for spinal disorders, a Roland-Morris Disability Questionnaire (RMDQ) score >= 6, and persistent LBP >= 2 with a maximum >= 4 using numerical rating scale. Patient-centered outcomes include LBP using visual analog scale, RMDQ, and PROMIS-29. Lumbar spine stiffness is assessed using palpation, a hand-held instrumented device, and an automated device. Flexion-relaxation is assessed using surface electromyography at the third level of the lumbar spine. Biomechanical characteristics of SM are assessed using a self-reported, itemized description system, as well as advanced kinetic measures that will be applied to estimate forces and moments at the lumbar segment level targeted by SM.Discussion: Beside alterations in material properties of the passive components of the spine, increased neuromuscular activity may also contribute to a stiffened spine. Examining changes in both spinal stiffness and flexion-relaxation along the course of the treatment provides an opportunity to understand if the therapeutic effect of SM is associated with its action on active and/or passive components of the spine.

Previous studies have indicated that changes in stance posture could directly influence trunk kinematics and potentially change the lumbar tissue synergy. In this study, the effects of stance width and foot posture on the lumbar muscle relaxation responses during trunk flexion were investigated. Methods Thirteen volunteers performed trunk flexion using three different stance widths and 'toe-forward' or 'toe-out' foot postures (six conditions in total). Lumbar muscle electromyography was collected from the L3 and L4 level paraspinals; meanwhile three magnetic motion sensors were placed over the S1, T12, and C7 vertebrae to track lumbar and trunk kinematics. The lumbar angle at which muscle activity diminished to a near resting level was recorded. At the systemic level, the boundary where the internal moment started to shift from active to passive tissues was identified. Findings For the L3 paraspinals, the flexion relaxation lumbar angle reduced 1.3 with the increase of stance width. When changed from 'toe-forward' to 'toe-out' foot posture, the flexion relaxation lumbar angle reduced 1.4 and 1.1 for the L3 and L4 paraspinals respectively. However, the active and passive lumbar tissue load shifting boundary was not affected. Interpretation Findings of this study suggest that changes in stance width and foot posture altered the lumbar tissue load sharing mechanism. Therefore, in a clinical setting, it is critical to maintain consistent stance postures when examining the characteristics of lumbar tissue synergy. © 2013 Elsevier Ltd.

Intramuscular activity was recorded with an intramuscular electromyographic (EMG) needle inserted into a latent MTP or a non-MTP in the upper trapezius at rest and during isometric shoulder abduction at 90 performed at 25% of maximum voluntary contraction in 15 healthy subjects. Surface EMG activities were recorded from the middle deltoid muscle and the upper, middle, and lower parts of the trapezius muscle. Maximal pain intensity and referred pain induced by EMG needle insertion and maximal pain intensity during contraction were recorded on a visual analog scale. The results showed that higher visual analog scale scores were observed following needle insertion and during muscle contraction for latent MTPs than non-MTPs (P <.01). The intramuscular EMG activity in the upper trapezius muscle was significantly higher at rest and during shoulder abduction at latent MTPs compared with non-MTPs (P <.001). This study provides evidence that latent MTPs are associated with increased intramuscular, but not surface, EMG amplitude of synergist activation. The increased amplitude of synergistic muscle activation may result in incoherent muscle activation pattern of synergists inducing spatial development of new MTPs and the progress to active MTPs. Perspective This article presents evidence of increased intramuscular, but not surface, muscle activity of latent MTPs during synergistic muscle activation. This incoherent muscle activation pattern may overload muscle fibers in synergists during muscle contraction and may contribute to spatial pain propagation. © 2014 by the American Pain Society.

SF-CV findings were compared with conventional nerve conduction studies (NCS). Methods: Twenty-eight consecutive type 2 diabetic patients with clinically diagnosed DSP were studied. Results: SF-CV testing of the tibial nerve was abnormal in 16 (57.1%) patients. Twelve patients with normal conventional motor NCS had abnormal findings by tibial SF-CV. SF-CV testing of the tibial nerve was significantly superior to all other motor NCS. Conclusions: SF-CV testing of the tibial nerve often demonstrates motor nerve impairment in diabetic patients with sensory DSP when conventional NCS are normal. © 2013 Wiley Periodicals, Inc.

Methods: This was a cross-sectional study in a laboratory setting. Thirty asymptomatic participants performed standing full trunk flexion and slumped sitting postures while activation levels of the lumbar erector spinae and superficial lumbar multifidus were monitored. Two thresholds were used to define whether FRP was present in each muscle and, if present, at what trunk flexion angle it occurred. These outcomes were compared descriptively between muscles and between postures. Results: Most participants displayed FRP in both muscles during standing full flexion; occurrences were more variable in slumped sitting. On average, FRP during standing full flexion and slumped sitting occurred at approximately 80% and 52% of participants' maximum flexion value, respectively. Variability in the slumped sitting onset angles was greater than that in standing full flexion. Conclusion: Outcomes for FRP during standing full flexion in asymptomatic participants appeared to be more robust and were not affected by the choice of either lumbar erector spinae or superficial lumbar multifidus. Conversely, during slumped sitting, FRP occurrence varied substantially depending on choice of muscle, although onset angles were relatively consistent between muscles. Although the choice of one muscle over the other may be warranted, it may be prudent to examine both muscles during FRP investigations in sitting postures, in order to fully characterize the behavior and activation patterns of the lumbar musculature.

The purpose of this study was to compare isotonic and isokinetic exercise by surface electromyography (EMG) analysis using standardized methods.Nine stroke patients performed three sets of isotonic elbow extensions at 30% of their maximal voluntary isometric torque followed by three sets of maximal isokinetic elbow extensions with standardization of mean angular velocity and the total amount of work for each matched set in two strengthening modes. All exercises were done by using 1-DoF planner robot to regulate exact resistive torque and speed. Surface electromyographic activity of eight muscles in the hemiplegic shoulder and elbow was recorded. Normalized root mean square (RMS) values and co-contraction index (CCI) were used for the analysis.The isokinetic mode was shown to activate the agonists of elbow extension more efficiently than the isotonic mode (normalized RMS for pooled triceps: 96.0 +/- 17.0 (2nd), 87.8 +/- 14.4 (3rd) in isokinetic, 80.9 +/- 11.0 (2nd), 81.6 +/- 12.4 (3rd) in isotonic contraction, F[1, 8] = 11.168; P= 0.010) without increasing the co-contraction of muscle pairs, implicating spasticity or synergy. © 2013 Elsevier Ltd.

We tested the hypothesis that the neural control of muscles during reaching in the presence of nociceptive input is determined by a reorganization of muscle synergies with respect to control conditions. Muscle pain was induced by injection of hypertonic saline into the anterior deltoid muscle of eight men. Electromyographic (EMG) signals were recorded from 12 upper limb muscles as subjects performed a reaching task before (baseline) and after the injection of hypertonic (pain) saline, and after the pain sensation vanished. The EMG envelopes were factorized in muscle synergies, and activation signals extracted for each condition. Nociceptive stimulation resulted in a complex muscle reorganization without changes in the kinematic output. The anterior deltoid muscle activity decreased in all subjects while the changes in other muscles were subject specific. Three synergies sufficed to describe the EMG patterns in each condition, suggesting that reaching movements remain modular in the presence of experimental pain. Muscle reorganization in all subjects was accompanied by a change in the activation signals compatible with a change in the central drive to muscles. One, two or three synergies were shared between the baseline and painful conditions, depending on the subject. These results indicate that nociceptive stimulation may induce a reorganization of modular control in reaching. We speculate that such reorganization may be due to the recruitment of synergies specific to the painful condition. © 2014 the American Physiological Society.

Fifteen participants performed three isometric force-matched tasks (single leg knee extension, single leg squat, and bilateral leg squat) in three conditions (Control, Pain, and Washout). Pain was induced by injection of hypertonic saline into the vastus medialis muscle (VM; left leg). Supersonic shear imaging was used to measure muscle shear elastic modulus as this is considered to be an index of muscle stress. Surface electromyography (EMG) was recorded bilaterally from six muscles to assess changes in neural strategies. During tasks with fewer degrees of freedom (knee extension and single leg squat task), there was no change in VM EMG amplitude or VM shear elastic modulus. In contrast, during the bilateral leg squat, VM (-32.9 +/- 15.8%; P < 0.001) and vastus lateralis (-28.7 +/- 14.8%; P < 0.001) EMG amplitude decreased during Pain. This decrease in activation was associated with reduced VM shear elastic modulus (-17.6 +/- 23.3%; P = 0.029) and reduced force produced by the painful leg (-10.0 +/- 10.2%; P = 0.046). This work provides evidence that when an obvious solution is available to decrease stress on painful tissue, this option is selected. It confirms the fundamental assumption that motor adaptations to pain aim to alter load on painful tissue to protect for further pain and/or injury. The lack of adaptation observed during force-matched tasks with fewer degrees of freedom might be explained by the limited potential to redistribute stress or a high cost induced by such a compensation. © 2014 the American Physiological Society.

Although verbal methods (e.g., pain scales and questionnaires) are commonly used to measure clinical pain, they tend to lack objectivity, reliability, or validity when applied to mentally impaired individuals. Biopotential and behavioral parameters may represent a solution. Such coding systems already exist, but they are either very costly or time-consuming or have not been sufficiently evaluated. In this context, we collected a database of biopotentials to advance an automated pain recognition system, determine its theoretical testing quality, and optimize its performance. For this purpose, participants were subjected to painful heat stimuli under controlled conditions. One hundred thirty-five features were extracted from the mathematical groupings of amplitude, frequency, stationarity, entropy, linearity, and variability. The following features were chosen as the most selective: (1) electromyography corrugator peak to peak, (2) corrugator shannon entropy, and (3) heart rate variability slope RR. Individual-specific calibration allows the adjustment of feature patterns, resulting in significantly more accurate pain detection rates. The objective measurement of pain in patients will provide valuable information for the clinical team, which may aid the objective assessment of treatment (e.g., effectiveness of drugs for pain reduction, information on surgical indication, and quality of care provided to patients).

In addition to being associated with a variety of malformations, SCM may occur with spinal cord tumors, with only exceptional cases involving teratomas. As only eight patients with a teratoma associated with SCM have been reported, their presentation characteristics and treatment are currently unclear. We review the literature of all patients with SCM with concurrent spinal teratoma, discuss the potential dysembryology, and report the first case of SCM with concurrent spinal teratoma in an elderly patient. The mean age of those with concurrent SCM and teratomas was 39.4 years, with 55.6% occurring in females. The lumbar spine was the most frequent location for teratomas (66.7%), with the Type II malformation more commonly occurring with these tumors (75%). The duration of symptoms varied widely, ranging from 1 month to 5 years, with the average duration being nearly 2 years. Back pain (87.5%) and lower extremity weakness (75%) were the most common presenting symptoms. As SCM may be associated with progressive neurological deterioration and teratomas can contain immature or malignant components, surgery should be attempted with the goal of gross total resection. Nonetheless, in patients with a concurrent tumor and spinal dysraphism, spinal teratomas should be considered in the differential diagnosis. Gross total resection of these lesions may be safely achieved even in the presence of SCM using intraoperative electrophysiologic monitoring. © 2013 Elsevier Ltd. All rights reserved.

Proximal MGA is an under recognized anastomosis between the ulnar and median nerves at or above the elbow and should not be missed during nerve conduction studies. We presented two patients with ulnar neuropathy mimicking findings including numbness and tingling of the 4th and 5th digits and mild weakness of intrinsic hand muscles. However, both cases had an apparently remarkable conduction block between the below- and above-elbow sites that was disproportionate to their clinical findings. To explain this discrepancy, a large MGA was detected with stimulation of the median nerve at the elbow. Thus, proximal MGA should be considered in ulnar neuropathy at the elbow when apparent conduction block or/and discrepancy between clinical and electrodiagnostic findings is found.

We investigated the extent to which development and recovery of fatigue during repeated bouts of an occupationally relevant reaching task was influenced by the difficulty of a cognitive activity between these bouts. Eighteen male volunteers performed three experimental sessions, consisting of six 7-min bouts of reaching alternating with 3 minutes of a memory test differing in difficulty between sessions. Throughout each session, recordings were made of upper trapezius muscle activity using electromyography (EMG), heart rate and heart rate variability (HRV) using electrocardiography, arterial blood pressure, and perceived fatigue (Borg CR10 scale and SOFI). A test battery before, immediately after and 1 hour after the work period included measurements of maximal shoulder elevation strength (MVC), pressure pain threshold (PPT) over the trapezius muscles, and a submaximal isometric contraction. As expected, perceived fatigue and EMG amplitude increased during the physical work bouts. Recovery did occur between the bouts, but fatigue accumulated throughout the work period. Neither EMG changes nor recovery of perceived fatigue during breaks were influenced by cognitive task difficulty, while heart rate and HRV recovered the most during breaks with the most difficult task. Recovery of perceived fatigue after the 1 hour work period was also most pronounced for the most difficult cognitive condition, while MVC and PPT showed ambiguous patterns, and EMG recovered similarly after all three cognitive protocols. Thus, we could confirm that cognitive tasks between bouts of fatiguing physical work can, indeed, accelerate recovery of some factors associated with fatigue, even if benefits may be moderate and some responses may be equivocal. Our results encourage further research into combinations of physical and mental tasks in an occupational context. Copyright © 2014 Mathiassen et al.

A total of 20 participants performed a bimanual push task using three frequencies (4, 8, 16 pushes/min), three loads (1 kg, 2 kg, 4 kg) and two grip conditions (no grip, 30% maximum). The coefficient of variation (CoV) of muscle activity was determined for the anterior deltoid, biceps brachii, extensor digitorum and flexor digitorum superficialis. Faster push frequencies and heavier loads had lower work-rest ratio CoV and higher mean muscle activity (p < 0.01). Sixteen pushes per minute produced the lowest CoV for the anterior deltoid (p < 0.01), while the 1- kg load produced the lowest CoV for the extensor digitorum and flexor digitorum superficialis (p < 0.01). Changes were driven by the rest phase rather than by the work phase, except for grip decreasing forearm muscle CoV. These findings underscore the importance of variability at rest and indicate that low variability of muscle activity is associated with ergonomic risk factors. PRACTITIONER SUMMARY: Decreased motor variability has been associated with pain and injury. A cyclical push task, evaluated in terms of work and rest phases, found that greater workloads increased variability primarily due to changes in the rest phase. Muscle variability, especially for the rest phase, may provide insight into injury risk.

METHODS: Forty-six patients with non-specific chronic LBP and 23 healthy controls were asked to perform a trunk muscles fatigue protocol. Surface electromyography was recorded using two adhesive matrix of 64 electrodes applied bilaterally over the erector spinae. Pain score, kinesiophobia and physical disability were analyzed through different questionnaires. To characterize motor variability, dispersion of muscular activity center of gravity was computed. Motor variability between groups was compared using repeated-measures analyses of variance. RESULTS: Score of disability and kinesiophobia were significantly higher in patients with LBP. Results indicated a significant group effect characterized by an increased motor variability in the healthy group through the entire fatigue task on the left (p = 0.003) and right side (p = 0.048). Interestingly, increasing muscle fatigue led to increased motor variability in both groups (on both sides (p < 0.001) but with a greater increase in the healthy group. CONCLUSION: Muscle recruitment is altered in patients with chronic LBP in the presence of muscle fatigue. Consequently, these patients exhibit changes in muscle recruitment pattern and intensity (lower levels of motor variability) during sustained isometric contraction that may be attributed to variation in the control of motor units within and between muscles. However, patients with LBP are able to increase their motor variability over time but with a lower increase compared to healthy participants.

Treatment outcomes remain unpredictable, with a large percentage of athletes unable to return to sport. There is considerable debate about the optimal treatment between debridement, repair, and tenodesis. HYPOTHESIS: Labral repair more closely restores neuromuscular control and motion during the overhand pitch than tenodesis of the long head of the biceps. STUDY DESIGN: Controlled laboratory study. METHODS: Eighteen pitchers, including 7 uninjured controls, 6 players pitching after SLAP repair, and 5 players pitching after subpectoral biceps tenodesis (BT), underwent simultaneous surface electromyographic measurement at 1500 Hz and motion analysis at 120 Hz with a 14-camera markerless motion analysis system and high-speed video (120 Hz) to confirm accurate motion tracking. Patients had undergone surgery at least 1 year previously and had returned to pitching with a painless shoulder. RESULTS: No significant differences were observed in the long head of the biceps muscle, short head of the biceps muscle, deltoid, infraspinatus, or latissimus activity between controls, patients after SLAP repair, and patients after BT. The variability from pitch to pitch for each study participant was similar between groups. Based on visual inspection of the activity time plots, BT appeared to more closely restore the normal pattern of muscular activation within the long head of the biceps muscle than did SLAP repair. There were no significant differences between controls and postoperative patients in the majority of pitching kinematics; however, pitchers after SLAP repair showed significantly altered patterns of thoracic rotation (P = .034) compared with controls and were significantly less likely to fall into previously published normal values for lead knee flexion at front foot contact (P = .019). CONCLUSION: While both BT and SLAP repair can restore physiologic neuromuscular control, pitchers who undergo SLAP repair may exhibit altered patterns of thoracic rotation when compared with controls and pitchers who undergo BT. CLINICAL RELEVANCE: While both tenodesis and SLAP repair can restore physiologic neuromuscular control, SLAP repair may alter pitching biomechanics. Copyright © 2014 The Author(s).

A total of 21 healthy subjects performed motor tasks, comprising tooth clenching at 5, 10 and 20 N. During all measurements, subjects kept the novel bite device between the anterior teeth during tooth clenching. The EMG study (n = 15) characterised jaw muscle activity for the three motor tasks and demonstrated significant differences in root mean square (RMS) EMG amplitude between 5-, 10- and 20-N tooth clenching (F = 46.21, P < 0.001). There were no differences in variability of muscle activity between the three tooth-clenching levels. In an fMRI pilot study (n = 6), statistical comparisons were used to identify brain regions with significant activation in the subtraction of baseline from 5- or 20-N tooth-clenching activity. 5- and 20-N tooth clenching significantly and bilaterally activated the sensorimotor cortex, supplementary motor area, cerebellum and basal ganglia (P < 0.05, corrected for multiple comparisons). However, activation of each brain region did not differ significantly between two tooth-clenching tasks. Based on these preliminary findings, we propose that the novel biting device may be useful in further fMRI studies on controlled jaw muscle activation patterns in different craniofacial pain conditions. In addition, our fMRI result suggests that there are no significant differences in brain activity within low levels of tooth clenching with controlled force. Copyright © 2014 John Wiley & Sons Ltd.

As workstation concepts are supported by subjective arguments only, the aim of this study was to use objective measurements to compare the variability of strain in various concepts: a dental chair equipped with a cart or an over-the-patient delivery system without an assistant, and Dr Daryl Beach's concept with an assistant. Goniometric and electromyographic recordings were made on 8 subjects, during a scaling operation. The electrical activity of their trapezius and lumbar muscles was compared, as were their cervical and lumbar ranges of motion. The results showed that there was a wide variability depending on the workstation. However, the Beach concept tended to reduce physical strain on most parameters: duration of left lumbar muscle activity (2% compared to 15% of time spent in > 10% maximal voluntary contraction, MVC), time spent in cervical side bending (4% compared to 30%), cervical flexion of > 20degree (9% compared to 40%), and left trapezius activity (9% of time spent > 10% MVC compared to 28%). Practitioners and students should adjust their workstations to reduce the prevalence of MSDs.

In line with this, positive associations between eye-related pain and muscle blood flow in orbicularis oculi have been observed. A hypothesis regarding work situations with cognitive tasks and low-level muscle activity, such as computer work, proposes that muscle pain originates from the blood vessel-nociceptor interactions of the connective tissue of the muscle. Noninvasive muscle blood flow measurements in the orbicularis oculi muscle are preferable to using an invasive technique. The aim of this study was to test reproducibility and stability of muscle blood recordings in orbicularis oculi using photoplethysmography. METHODS: In the reproducibility tests, 12 subjects were tested twice within 1 to 5 weeks. To study the stability of the method, six of the subjects were randomly selected and tested four more times within 2 to 6 weeks. Test subjects were doing identical visually demanding computer work for 10 minutes in each test. RESULTS: The short-term repeatability of muscle blood flow measurements was considered good, but the stability of blood flow recordings over time in orbicularis oculi was low because of a greater within-subject maximum variability compared with between-subject average variability. CONCLUSIONS: Investigators should be aware of the effect of time, possibly attributed to confounding factors such as environmental changes and mental stress, when comparing photoplethysmography muscle blood flow recordings.

Accordingly, this study investigated motions of the trunk and the knee, control of dynamic stability and muscle activation patterns of individuals with and without knee pain. Seventeen participants with chronic knee pain and 17 healthy participants participated in the study and performed forehand forward and backward diagonal lunges. This study showed that those with knee pain exhibited smaller knee motions in frontal and horizontal planes during forward lunge but greater knee motions in sagittal plane during backward lunge. By contrast, in both tasks, the injured group showed a smaller value on the activation level of the paraspinal muscles in pre-impact phase, hip-shoulder separation angle, trunk forward inclination range and peak centre of mass (COM) velocity. Badminton players with knee pain adopt a more conservative movement pattern of the knee to minimise recurrence of knee pain. The healthy group exhibit better weight-shifting ability due to a greater control of the trunk and knee muscles. Training programmes for badminton players with knee pain should be designed to improve both the neuromuscular control and muscle strength of the core muscles and the knee extensor with focus on the backward lunge motion.

Hypothesis: Hg poisoning in pediatric patients can occur with topical use of facial creams containing inorganic Hg. Methods: A healthy 17-year-old boy presented with insomnia, lower extremity muscle weakness, extremity tingling, and low back pain. He reported a loss of balance and coordination while playing soccer. Later, he developed hypertension (148/84 mmHg) and extremity fasciculations. Initial workup revealed normal CBC, CK, UA, serum electrolytes, Ca, Mg, CRP, TSH, AST, and MRI of the spine. An EMG revealed diffuse myopathic fasciculations. Prednisone resulted in no significant improvement. His symptoms worsened including severe fasciculations, hallucinations, ataxia, hypertension (170/90 mmHg), and tachycardia (150 bpm). He was admitted to the pediatric intensive care unit due to hyperadrenergic signs and hallucinations. Initial working diagnosis was pheochromoctyoma. Morvan's fibrillary chorea was then presumed and a 5-day course of IVIG was administered. Three generalized seizures developed. A medical toxicology consultation was then requested. Results: Toxicology lab testing revealed elevated blood Hg levels of 208 mug/L. Home inspection revealed unlabeled jars of acne facial cream from Mexico containing mercurous chloride (96,00-210,000 ppm Hg). Lumex measurements in the patient's room were 2.6 mug/mm3. The patient used facial cream daily for 6 weeks and stopped 1 month prior to the first Hg level. Treatment included a full course of succimer. Hypertension was managed with diltiazem. Sleep and pain were managed with amitriptyline. Fasciculations, back pain, insomnia were present at 3 months. At 6 months follow-up, he had rejoined his soccer team but continued on diltiazem for persistent hypertension and tachycardia. Discussion: It is important to obtain a full medication history in adolescents using various acne treatments. Hg poisoning in pediatric patients is most commonly confused with pheochromocytoma and Kawasaki's disease. Patients presenting with similar symptoms yet an incomplete picture should prompt an evaluation for Hg poisoning. Conclusion: Determination of Hg toxicity may be challenging. Awareness of acne treatment facial products may prompt an early diagnosis of Hg poisoning. This case demonstrates collaboration between local and state health departments and a toxicology service.

ICU admitted patients are at high risk of dyspnea, and of not being able to describe it using a mere visual analog scale (VAS). This study assessed the respiratory distress observation scale (RDOS), a hetero-evaluation dyspnea scale validated in palliative care, in "day one" ICU patients. Methods. In 193 patients admitted to a 16-bed ICU (4 months), we recorded dyspnea, anxiety and pain VAS, RDOS components (breathing frequency, heart rate, accessory muscle activity, nasal flaring, abdominal paradox, expiratory grunting, restlessness, frightened look), various physiological data and disease and treatment descriptors. VAS and RDOS were compared using Spearman's correlation. RDOS ability to detect a VAS>3 was studied using ROC curves. A principal component analysis (PCA) was conducted with the aim of developing a ICU-RDOS. Results. VAS proved impossible in 73 patients. In the remaining 120, RDOS was moderately correlated with VAS (rho=0.45, 95%CI 0.29-0.58, p<0,01) (Figure). RDOS>3 had a 95.5% specificity (95%CI 87.5-99.1) to predict VAS>3. In PCA, two vectors explained 36.2% of the data set variability. F1 (25.9%) included breathing frequency, accessory muscle activity, nasal flaring, and a frightened look. F2 (10.3%) included abdominal paradox, restlessness, a frightened look, and breathing frequency. It proved possible to improve the performance of RDOS both in terms of correlation with EVA (rho = 0.612) and area under ROC curve by selecting a subset of the RDOS descriptors and adding new physiogical variables (heart rate, respiratory admission, paradoxical breathing, accessory muscle activity, frightened look). Conclusion. It seems possible to identify ICU patients higly likely to suffer from dyspnea from hetero-observed signs. This might improve dyspnea management in this setting. (Figure Presented).

For the insertion of the fixators two surgical techniques have been established: the traditional opensurgery (OS) and the newly developed minimally-invasivesurgery (MIS). Comparative studies between OS and MIS techniques with respect to effects on paravertebral muscle function do not exist so far. Method: 10 male patients were examined, five underwent OS (BMI: 26+/-3; age at time of the accident 46+/-14 years; mean +/- SD) and five MIS (BMI: 26+/-1; age at time of the accident 46+/-9 years) were compared with 29 healthy men (BMI: 25+/-3; age 37+/-13 years). Each patient was examined three times, at first one day prior to the initial surgery (U1; surgery: additional thoracoscopic anterior vertebral body replacement about 6 weeks after dorsal OS or MIS), 6 weeks (U2), and 6 months (U3) thereafter. Paravertebral co-ordination patterns were measured during static load situations of the paraspinal muscles using surface electromyography, on both sides, starting from the spinous process of the 5th lumbar spine, cranially over a length of 40cm. was Applied load levels were 9%, 17%, 34%, 50%, 71%, 87%, and 100% of the individual upper body mass (OBM). Pain was rated using a VAS. Differences of spatial activation patterns between patients and healthy subjects were tested using the nonparametric U-tests for each load level and each segment (global alpha-level: 0.05, adjusted for number f tests), respectively. Results: Spatial activation patterns between patients and controls do not differ systematically at any time (Figure 1). In general, patterns are such that highest SEMG amplitudes occur in the lumbar area. Only in MIS patients at U3 significant differences at L2 left and at L1 to L2 at right side occur during 100% UBM application. At U1, in one OS patient pain (VAS 34/100) appeared in the surgery region. At U2 four patients (mean VAS 44 (+/-11) / 100), and three patients at U3 (mean VAS 51 (+/-11) / 100) showed severe pain. In the group of MIS patients, one patient (VAS 41/100) at U1 and two patients (U2: VAS 47/100 and 33/100; U3: VAS 50/100 and 49/100) at the other two times had severe pain. Only one OS patient but three MIS patients were pain free at all examination times. Discussion: For spinal fusion, open and minimally invasive surgery do not affect paravertebral muscule co-ordination patterns. Therefore, the results cannot prove any advantage of either methods as was found in other studies. The lesser tissue alteration by application of MIS and the therefore assumable minimized denervation cannot be shown in paravertebral activation pattern. Only one patient of each group showed pain before U1. After the ventral thoracoscopic surgery pain occurrence together with pain intensity raised considerably. Therefore, the thoracoscopic procedure itself seems to play a key role for the development of post-surgery pain after spinal fusion. (Figure Presented).

It hasmany roles, described as an internal rotator of the humerus, a shoulder abductor, a humeral head depressor and an anterior stabiliser. As studies have traditionally evaluated the subscapularis muscle as a single muscle unit, the aims of the study were to investigate if differences exist in the level of muscle activity between upper and lower subscapularis during seven MVIC positions and four shoulder movements, as well as temporal characteristics during abduction and flexion. Methods: Intramuscular electrodes recorded electromyographic muscle activity from the upper and lower subscapularis muscles of the dominant throwing arm of twenty-four normal subjects (mean age = 23.6 yrs, range = 18-37 yrs) with no history of shoulder pain, injury or surgery. Participants completed ten repetitions of four shoulder movements - abduction, flexion, internal rotation and external rotation and three repetitions of seven maximal voluntary isometric contractions. An accelerometer angle processor was placed on the participants' wrist to measure the start and finish of motion and the shoulder angle during dynamic movements. Data was processed using Delsys EMG works software package and the muscle activity was expressed as a percentage of maximum voluntary isometric contraction. Results: The lower subscapularis was found to activate at a higher level than the subscapularis during abduction, flexion and external rotation movements. However, only during abduction were differences between the two muscle components found to be significant (p = 0.018). During internal rotation, upper subscapularis muscle activity mirrored that of lower subscapularis, with a mean difference of 1.14%. Neither upper nor lower subscapularis had onset data commencing prior to the abduction movement how-ever upper subscapularis activated significantly later than lower subscapularis (p = 0.02). Flexion temporal data were not compared due to the minimal detectable activity of subscapularis. Discussion: The lower subscapularis activates at a significantly higher muscle activity than upper subscapularis during shoulder abduction in a normal population. Greater activity was seen in lower subscapularis during flexion however this was not significant. Additionally, lower subscapularis activated significantly earlier than the upper segment in abduction. This may indicate different roles for each segment during some shoulder motions and a different functional role at that commencement of movement.

Though the activity of tibialis anterior (TA) in a single stride is prevalent during the loading response and the swing phase, further activation modalities may appear during gait, with a different number of activity intervals [1,2]. The aim of this study was to describe the different modalities of TA activations, in terms of on/off time instants and amplitude of EMG signal. Methods: Fourteen healthy volunteers were recruited for this study, signing informed consent.Meanvalues (+/-SE) were 23.9+/-0.6 years for age; 174+/-2cm for height and 63.4+/-3.8 kg for weight. Mean body mass index (BMI) was 20.7+/-0.6 kgm2 and male/female ratio was 7/7. Exclusion criteria included history of neurological pathology, acute or chronic knee pain, orthopedic surgery within the previous year or BMI > 25. All participants signed informed consent. EMG signals were acquired by means of a multi channel recording system for statistical gait analysis (Step 32, Demitalia, Italy). Both lower limbs were instrumented with three footswitches, below the heel and the first and fifth metatarsal heads; single differential EMG probes were attached over TA, following the SIAMOC protocol. Each participant was instructed to walk barefoot at their personal pace. The amplitude of the signal has been normalized to the peak value (PV) and then represented by a three-level scale, in order to describe the differences of intensity of the myoelectric activity during the gait cycle. Results: For each subject a mean of 450+/-34 strides has been considered. The analysis of EMG signal shows several activation modalities for TA: those with two, three and four activation result the most recurring ones, occurring in a mean of 30.8+/-4.5%, 36.5+/-2% and 21.8+/-2.7% of total strides, respectively. The 2- activation modality presents the first activity in correspondence of heel strike event, while the second one lasts for the whole swing phase. In the 3-activation modality the initial activation was observed after heel strike, the second activation is in the final part of push-off and the third one occurs from mid-swing to the end of gait cycle. The 4-activation modality is characterized by an activity during heel contact, one in mid-stance and two further during swing (Fig. 1). The average amplitude of this latter activation is rather low, no more than 12.3+/-3.2% of the PV while for first, third and fourth activations an average amplitude of 91.4+/-4.2%, 50.6+/-5.1% and 86.4+/-4.5% of the PV was observed, respectively. Discussion: The present analysis shows a considerable variability in TA activity during walking. Three main modalities of activation have been observed; all these modalities are characterized by the typical TA activity [3], focused on two main areas: the beginning and the end of gait cycle, i.e. loading response and swing phases. However, in the 4-activation modality a further activity on mid-stance phase (around 30% of gait cycle) was observed (Fig. 1). Similar TA activity during mid-stance has recently been observed in young adults [2] and children [1]. The low amplitude of the signal in this phase of gait cycle (~ 10% of PV) suggests that this type of activity does not occur for ankle flexion, but could be related to the less demanding task of inversion of the foot, to control balance during single support.

More recently, technologic advances have extended these techniques to pathologies of spine, as multimodality IOMis sensitive and specific for detecting intraoperative neurological injury. It is suggested this be considered in spinal decompression where the spinal cord and/or nerve roots are at risk, including procedures which require instrumentation. As patient access and technology evolve, surgeons well versed in these modalities are paramount for their continued valuable and safe application.

Intraoperative Neurophysiological Monitoring (IOM): Intraoperative monitoring dates back to the first half of the 12th century when it was used for epilepsy surgery. At that time, Penfield and Boldrey used direct cortical stimulation to map the motor and sensory homunculus.i It wasn't until several decades later that electroencephalography (EEG) was used in carotid endarterectomy (CEA).ii During the infancy of these procedures, the patient was kept awake during the carotid clamping because of worries about cortical ischemia. Since better ways to evaluate ischemia were being researched, EEG provided a means of determining what degree of ischemia could be tolerated during surgery. In the 1970s, spinal instrumentation and aggressive surgical technology came into wide spread use for the treatment of severe spinal deformities. Cord monitoring grew from the early 1970s research, which discovered electrical spinal potentials (EP's) were obtainable from the epidural space upon direct spinal stimulation. 1970's research also lead to the discovery that Somatosensory EPs (SEPs) could be recorded from the scalp.iii Nash and colleagues initially applied these SEPs in the operating room, but were impeded by variability of signals and sensitivity to anesthesia.iv Problems remained for excess noise or irreproducible background variability. By the late 1970s, Nuwer and Dawson evaluated the causes of variability and determined that use of short-latency SEP techniques, restricted filters, and other technical modifications substantially reduced background variability and greatly improved reliability in the SEP tracings.v With these technical improvements, SEP became a widely adopted method of spinal cord monitoring during vertebral surgery. A somewhat different approach was developed in the UK, where Jones used the spinal recordings, but moved the stimulator to the posterior tibial nerve, thereby avoiding concerns regarding the safety of repeated spinal cord epidural electrical stimulation.vi In 1982, Grundy published a series of reports about anesthetic effects, described techniques to reduce adverse effects, and extended the techniques into neurosurgical procedures.vii For two decades, monitoring the sensory pathways with SEPs and measuring the epidural spinal potentials were the techniques of choice for spinal cord monitoring. As techniques improved there were still limitations, as those available monitored sensory and not motor tracts. The only way to monitor function at that time was the Wake Up Test developed by Vauzelle and Stagnara, and understandably these were found difficult to conduct under anesthesia. In 1980, Merton and Morton reported a technology to stimulate the brain transcranially, which opened the door for motor tract monitoring. Burke subsequently popularized the use of transcranial electrical stimulation as a practical corticospinal technique for use under anesthesia.viii Many monitoring teams now use this technique to measure corticospinal pathways in the operating room. Controversy remains however about where to measure the responses. Today, monitoring of motor-related pathways is routinely performed, yet no single method can sufficiently cover the complex functions of the spinal cord. Multimodality combinations of the available technologies are thus considered necessary for practical and effective intraoperative monitoring. Most common procedures include: Somatosensory Evoked Potentials (SSEP), Transcranial Motor Evoked Potentials (TcMEP), free Running EMG (EMG), and Spinal Cord Evoked Potentials (SCEP) however; SCEP is more common during "open" spinal cases and in this author's opinion, not necessary in spinal procedures unless other extenuating circumstances prevail. The American Academy of Neurology (AAN) convened a panel of experts who reviewed the results of a comprehensive literature search and identified published studies relevant to the clinical question of efficacy in IOM. These studies were classified according to the evidence-based methodology of the American Academy of Neurology. Objective outcomes of postoperative onset of paraparesis, paraplegia, and quadriplegia were used because no randomized or masked studies were available. Four Class I and 8 Class II studies met inclusion criteria for analysis. The 4 Class I studies and 7 of the 8 Class II studies reached significance in showing that paraparesis, paraplegia, and quadriplegia occurred in the IOM patients with EP changes compared with the IOM group without EP changes. All studies were consistent in showing all occurrences of paraparesis, paraplegia, and quadriplegia in the IOM patients with EP changes, with no occurrences of paraparesis, paraplegia, and quadriplegia in patients without EP changes. In the Class I studies, 16%-40% of the IOM patients with EP changes developed postoperative-onset paraparesis, paraplegia, or quadriplegia. IOM is established as effective to predict an increased risk of the adverse outcomes of paraparesis, paraplegia, and quadriplegia in spinal surgery (4 Class I and 7 Class II studies). Surgeons and other members of the operating team should be alerted to the increased risk of severe adverse neurologic outcomes in patients with important IOM changes (Level A).ix The conclusion reached by the AAN; was the release of an evidence-based guideline update that recommends monitoring evoked potentials during spinal surgery and certain chest surgeries to protect the spinal cord and lessen the danger of paralysis. x History: Francesco Redi discovered the first documented EMG experimentation in the electrical eel in 1666.xi In 1773, a British researcher JohnWalsh, demonstrated a visible spark from an eel's muscle tissue and by 1791, Luigi Galvani demonstrated that electricity could initiate muscle contraction.xii In 1849, Emil du Bois-Reymond noted that it was possible to record electrical activity during a voluntary muscle contraction.xiii Etienne-Jules Marey, was the first to obtain an actual recording of this activity, and introduced the term electromyography.xiv In 1922, Gasser and Erlanger used an oscilloscope to show the electrical signals from human muscles.xv The capability of detecting electromyographic signals improved steadily from the 1930s through the 1950s as researchers began to use improved electrodes more widely. Since the 1980's, technologic advances have resulted in expanded access, and today Nerve Conduction Studies (NCS) and Electromyography (EMG) are considered the gold standard in evaluating neuromuscular disorders. The availability of these studies however cannot supersede or replace the users critical neuroanatomical and neurophysiological knowledge. More importantly, poor knowledge, as well as poor testing techniques, commonly results in misdiagnosis.

Methods: Participants were a purposeful sample of children/youth on or off treatment for ALL with varying degrees of CIPN. Multidimensional assessment as outlined in the results and 3-D instrumented gait analysis were conducted. Analyses were descriptive. Normative values provide context. Results: Fourteen participants were assessed (median age 7 years, range 5-21), 6 males, 6 receiving maintenance therapy and 8 off treatment (mean time off 28 months, range 1-80). Data is presented as mean (standard deviation) [range]{normative}. Pediatric modified Total Neuropathy Scale:4.9 (2.7) [2-12]{0-4}; 6 minute walk test (metres) :400.3 (113.7) [180.0- 586.7]{400-600}; Bruininks-Oseretsky Test of Motor Proficiency Running Speed and Agility subtest (Standard Score): 1.1 (0.5) [1-3]{10-20}; Oxford Foot and Ankle Questionnaire (%) Physical: 46.1 (27.2) [0-75]{100}; School Play: 64.7 (31.6) [6.3-100]{100}; Emotional: 80.2 (24.8) [25.0-100]{100}; Shoe Wear 69.5 (36.7) [0-100]{100}; Gross Motor Function Measure-ALL (%) Standing 88.4 (11.8) [66-100]{100}; Walk, Run, Jump 81.6 (14.2) [50- 100]{100}; Pediatric Outcomes Data Collection Instrument Transfers and Basic Mobility: 36.7 (27.2) [-49-53]{50}, Sport and Physical Functioning 24.1 (19.0) [-27.0-42]{50}, Pain and Comfort 33.4 (19.7) [-6-57]{50}; Edinburgh Gait Scale: 6.2 (4.6) [0-14]{0}. Common kinematic gait characteristics included knee hyperextension, decreased dorsiflexion, delayed heelrise, and decreased ankle plantarflexion pre swing in stance; and decreased ankle dorsiflexion with compensatory hip and knee motion in swing. Temporal spatial data showed reduced step length with a corresponding reduction in velocity. Kinetics demonstrated decreased ankle moments/power generation at push off. Tibialis anterior and gastrocnemius electromyography showed timing and amplitude abnormalities. Conclusions: Multi-dimensional functional assessment in children/youth participants treated for ALL demonstrated variability in impairments, activity limitations, and participations restrictions related to CIPN. These measures have the potential to inform clinical decision making regarding vincristine dosing, exercise, and orthotics; facilitate evaluation over time; and provide tools for further research of the impact of CIPN during and following treatment for ALL.

Swallowing can occur normally prior to or during expiration or pathologically during inspiration. The aspiration risk is more likely to be increased if swallowing occurs just prior to or during inspiration1. Currently, it is unclear if the incidence and timing of swallowing are modulated by anesthetics or changes in ventilatory drive. We hypothesize that propofol and sevoflurane affect the incidence and timing of swallowing, and increasing ventilatory drive with CO2 can modulate these effects. METHODS: Following IRB approval, we studied 11 ASA I, volunteers aged 18-45 as part of a protocol that has been described previously2. Briefly, hypopharyngeal pressure was measured with a Millar catheter threaded nasally and secured by a nasal mask, connected to a high flow circuit. Pneumotachometry and capnometry were used to measure airflow and PETC02. Intramuscular genioglossus (GG) electrodes were used to measure phasic GG EMG. Equianesthetic doses (titrated to pain stimulus) of propofol (TCI) and sevoflurane were applied in a randomized cross over fashion. During wakefulness and anesthesia, the presence of spontaneous swallows was measured during inspiration and expiration. Measurements were also made during CO2 insufflation in order to obtain stable PETCO2 levels of 4 or 8 mmHg (all CO2 driven swallows are combined for analysis). The presence of a swallow was defined as a 200% increase in GG activity, deglutition apnea, and an increase in hypopharyngeal pressure by 15 cmH20. Swallows were categorized as expiratory (physiological) or inspiratory (pathological) (Fig. 1)3. We analyzed the data with a mixed linear model to identify the effects of anesthesia and/or the CO2-induced increase in ventilatory drive on swallows/hour and the percentage of expiratory vs. inspiratory swallows. RESULTS: 202 episodes met the criteria for swallows. There was a significantly lower number of swallows/hr during anesthesia (1.45 +/- 3.08) vs. wakefulness (25.13 +/- 18.516) (p < .001), but no significant difference between propofol (2.01 +/- 3.76) and sevoflurane (.90 +/- 2.31) (p = .421). The incidence of inspiratory swallows was higher during anesthesia vs. wakefulness (26.7% vs. 3.1%, p < .001) (Fig. 2). The incidence of inspiratory swallows was higher when ventilatory drive was increased by hypercapnia during anesthesia (38.5% vs. 12.1%, p = 0.047) (hypercapnia led to an average increase in minute ventilation of 0.54 L/min). CONCLUSIONS: Sevoflurane and propofol decrease the frequency of swallowing and increase the likelihood that a swallow will occur during or just prior to inspiration. This is likely to increase the risk for pulmonary aspiration. An increase in ventilatory drive - which may occur during procedural sedation in response to increased EtCO2 or a strong pain stimulus, further increases the likelihood of a inspiratory swallow and increases the risk for aspiration (Table Presented).

However, others are similarly flexible but suffer with pain, joint instability, weakness and fatigue. People who have joint hypermobility and symptoms are classified as having Joint Hypermobility Syndrome (JHS (1)). It is unclear why some flexible people have symptoms and some do not. However, it may be due to impaired mechanisms of control (2). Surprisingly, no one has investigated these mechanisms of control thoroughly. Objectives To assess the sample size required for an investigation comparing quadriceps corticospinal excitability between people with normal flexibility, people who are flexible without knee pain and people who have JHS with knee pain. Methods With ethical approval and informed consent, the surface electromyography of Quadriceps were recorded from 3 cohorts of age matched people; individuals with normal flexibility without knee pain (Beighton score of 3 or less), individuals with JHS (classified using the Brighton criteria (1)) without knee pain and individuals with JHS with knee pain. A figure of eight coil from a magnetic stimulator was positioned over the cortex upon the hotspot for Quadriceps, evoking a MEP in the muscle of the painful or dominant side. The stimulus strength was varied whilst the muscle was held at a constant, low level of contraction with the assistance of a feedback monitor. In addition, the maximum amplitude of the motor response (Mmax) to electrical stimulation of the femoral nerve was established. A recruitment plot was constructed of stimulus strength against MEP amplitude normalised to Mmax and a Boltzmann sigmoid curve was fitted. The threshold and latency of the MEP, the maximum amplitude of the normalised MEP, the slope of the recruitment curve and the stimulus required to evoke a response of 50% of the maximum amplitude (X50) were recorded and compared across groups. Normality of distribution was tested using Shapiro-Wilk test. If normally distributed a one way ANOVA or where data was not normally distributed, a Kruskal-Wallis one way analysis of variance on ranks was used to compare between cohorts. Using the standard deviation of the results, sample size estimates were calculated using a power of 0.8 and a probability of 0.05. Results 36 people were recruited aged 29.2yrs +/-6.6 (mean +/- standard deviation); 12 with normal flexibility (Beighton score 0.96+/-0.86), 11 with JHS without knee pain (6.37+/-1.54) and 13 with JHS and knee pain (6.04+/-1.67). Data was not normally distributed. No differences in threshold (p=0.33), latency of the MEP (p=0.45), maximum amplitude of the normalised MEP (p=0.58), slope of the recruitment curve (p=0.60) and the X50 (p=0.22) were found. Taking into account the variability of the data, this pilot investigation suggests a sample size of 30 in each group is required in order to exclude the possibility that these results are due to random sampling variability. Conclusions Differences to corticospinal excitability in JHS are yet to be elucidated; however differences may be subtle.

So far, the effects of BWU on the biomechanical gait parameters could not be determined since they were confounded by two intervening variables by the walking modality (treadmill as opposed to overground walking) and the variability in walking speed which could not be kept constant during overground walking with BWU. By designing a device capable of maintaining a constant speed this study aimed at examining the unique effects of BWU on the knee and hip biomechanical gait parameters under conditions that approximate daily walking. Methods: The research sample included ten healthy male subjects (mean age 23.8) with no history of gait impairment. A Biodex BWU system (Fig. 1) was used to unload various levels of body weight of the subjects using a supporting pelvic belt and overhead harness during overground walking. An electric winch (the new apparatus) was connected to the Biodex system (see Fig 1.) to pull the system and maintain the subjects' gait speed constant at 4km/h. Procedure: Subjects were asked to walk overground under a control condition of No Harness, and three experimental conditions of 0%, 15% , and 30% BWU. The biomechanical parameters of the hip and knee in the sagittal and frontal planes were recorded with an eight-camera infrared Vicon motion tracking system. The electromygraphic activity (EMG) of the Tibialis Anterior (TA), Lateral Gastrocnimius (Lat GC), and Vastus Lateralis (VL) was recorded using the surface EMG ZeroWire system. Results: No significant differences were indicated in flexion and extension of the joints during overground walking under 0%, 15% and 30% BWU levels (Fig.2a, 3a). Pairwise comparisons 0-15% BWU, 0-30% BWU and 15-30% BWU of the three experimental conditions indicated high highly correlations (r > 0.95; p<.001) between kinetic and kinematic data and low RMSEs for all comparisons. Significant differences in kinetic and impulse parameters in the sagittal and frontal planes were indicated under the three levels of BWU (Fig. 2b, 2c, 3b, 3c), with an increase in BWU level resulting in a significant (p<.01) decrease in peak moments and impulses.

Methodological issues in the 1990s research such as unilateral electromyography and a limited range of arm movements justify a re-examination of this theory. The hypothesis tested is that TrA bilateral co-contraction is a typical muscle synergy during arm movement. The activity of 6 pairs of trunk and lower limb muscles was recorded using bilateral electromyography during anticipatory postural adjustments (APAs) associated with the arm movements. The integrated APA electromyographical signals were analyzed for muscle synergy using Principle Component Analysis. TrA does not typically bilaterally co-contract during arm movements (1 out of 6 participants did). APA muscle activity of all muscles during asymmetrical arm movements typically reflected a direction specific diagonal pattern incorporating a twisting motion to transfer energy from the ground up. This finding is not consistent with the hypothesis that TrA plays a unique role providing bilateral, feedforward, multidirectional stiffening of the spine. This has significant implications to the theories underlying the role of TrA in back pain and in the training of isolated bilateral co-contraction of TrA in the prophylaxis of back pain. © 2013 .

During LBP remission, altered trunk muscle control has been suggested to negatively impact spinal health. As sudden LBP onset is commonly reported during trunk flexion, the aim of the current study is to investigate whether dynamic trunk muscle recruitment is altered in LBP remission. Eleven people in remission of recurrent LBP and 14 pain free controls performed cued trunk flexion during a loaded and unloaded condition. Electromyographic activity was recorded from paraspinal (lumbar and thoracic erector spinae, latissimus dorsi, deep and superficial multifidus) and abdominal muscles (obliquus internus, externus and rectus abdominis) with surface and fine-wire electrodes. LBP participants exhibited higher levels of co-contraction of flexor/extensor muscles, lower agonistic abdominal and higher antagonistic paraspinal muscle activity than controls, both when data were analyzed in grouped and individual muscle behavior. A sub-analysis in people with unilateral LBP (n=.6) pointed to opposing changes in deep and superficial multifidus in relation to the pain side. These results suggest that dynamic trunk muscle control is modified during LBP remission, and might possibly increase spinal load and result in earlier muscle fatigue due to intensified muscle usage. These negative consequences for spinal health could possibly contribute to recurrence of LBP. © 2012 Elsevier Ltd.

Linear and nonlinear parameters were computed from kinetics, kinematics and muscle activity recorded for 12 sub-acute patients and 12 healthy matched controls during trunk flexion, sit-to-stand from a chair and lifting a box. Cognitive variables were collected to explore relationships with biomechanical parameters. For trunk flexion, left external abdominal oblique muscle activity level was lower for patients compared with controls (p<. 0.05), whereas sample entropy (complexity) was higher (p<. 0.05). Normalized mutual information was lower for patients compared with controls for left and right erector spinae (p<. 0.05). Level of activity of left external abdominal oblique correlated negatively with cognitive ignoring and positively with catastrophizing (p<=. 0.05), and catastrophizing also correlated positively with functional connectivity of abdominal muscles (p<. 0.05). Signs of reorganization in muscle activation pointed towards different synergistic actions in trunk muscles in sub-acute LBP patients compared with controls. The interplay with maladaptive cognition suggested that in the subacute stage of LBP, both biomechanical and cognitive factors should be taken into account. © 2012 Elsevier Ltd.

We report a young patient whose classical NF1 stigmata and numerous spinal neurofibromas matched both groups. He carried a single base deletion, c.389delA in exon 4a, which creates a premature termination at codon 164.

The prevalence of neck pain in dentists is 74.3%. Musculoskeletal symptoms in dentists are caused due to many reasons for e.g., prolonged static posture, repetitive movements, suboptimal lighting, and genetic predisposition. Since deep cervical muscle activity is required in synergy with superficial muscle activity to stabilize the cervical segments, a study is needed, to compare the effectiveness of deep cervical flexor (DCF) training and posture correction training on neck pain and neck disability index and forward head posture. Aim: To determine and compare the effect of DCF training on forward head posture, neck pain and neck disability index in dentists suffering from chronic non severe neck pain. Material and Methods: Total of 30 subjects were selected, based on inclusion and exclusion criteria, who were further divided into Experimental and Control groups. Baseline information of dependent variables was taken at the beginning of study on day one, for Visual Analogue Scale (VAS) and Neck disability Index (NDI). Forward head posture was measured on day one using digital photograph technique. Then, Experimental group was given DCF training and Control group was given conventional isometrics training (CIT) for 4 weeks under supervision of examiner. All measurements were repeated at end of 4th week, on completion of study. Results: It was observed that pain and disability had reduced in both groups on group analysis. But the forward head posture had improved significantly in experimental group only. Conclusion: DCF training is more effective than CIT in improving forward head posture, decreasing pain and disability in dentists suffering from chronic neck pain.

While aberrant motion patterns can be detected visually, clinicians are unable to assess underlying neuromuscular strategies during these tests. The purpose of this study was to compare coordination of the trunk and hip muscles during 2 commonly used assessments for lumbopelvic control in people with low back pain (LBP) and matched control subjects. Electromyography was recorded from hip and trunk muscles of 34 participants (17 with LBP) during performance of the Active Hip Abduction (AHAbd) and Active Straight Leg Raise (ASLR) tests. Relative muscle timing was calculated using cross-correlation. Participants with LBP demonstrated a variable strategy, while control subjects used a consistent proximal to distal activation strategy during both frontal and sagittal plane movements. Findings from this study provide insight into underlying neuromuscular control during commonly used assessment tests for patients with LBP that may help to guide targeted intervention approaches. © 2013 Elsevier Ltd.

Lumbar erector spinae (ES), gluteus maximus (GM), and biceps femoris (BF) electromyographic (EMG) signals were recorded during a trunk flexion task where subjects were instructed to flex their trunk in the sagittal plane and then return to a neutral posture. The task was repeated under three footwear conditions: while wearing no footwear, while wearing shoes with 4-cm heels, and while wearing shoes with 10-cm heels. EMG onset and offset times, as well as EMG duration, were calculated for each muscle and compared across conditions. Results: We observed a significantly earlier onset of the ES EMG activity (1.36+/-0.61 vs. 1.56+/-0.67s), and significantly delayed onset of the GM EMG activity (1.72+/-0.66 vs. 1.28+/-0.58s) during the flexion phase of movement in the 10-cm heeled compared to the no footwear condition. The GM muscle also exhibited an earlier offset time in the 10-cm heel condition compared to the no footwear condition during the flexion movement (2.57+/-0.67 vs. 3.30+/-0.61s) as well as during the return from flexion movement phase (10.87+/-0.58 vs. 11.69+/-0.65s). These alterations in timing characteristic resulted in an overall decrease in the EMG duration for the GM muscle during the flexion movement. Conclusion: The results of this study suggest that high-heels alter trunk and hip extensor muscle coordination patterns. These findings, when considered in combination with other recent findings on the biomechanical effects of wearing high-heels, raise concern about whether wearing high heels results in abnormal spine loading patterns and increases the risk for developing musculoskeletal injuries. © 2013 Elsevier Ltd.

The four-point kneeling exercise is one of the most common types of stabilization exercises. This quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stages of the four-point kneeling exercise. Methods: The present study was conducted on 30 healthy women between 20 and 30 years old. Muscle activity was recorded bilaterally from transversus abdominis, internal oblique, and multifidus muscles with an electromyography (EMG) device during the different stages of the four-point kneeling exercise. All the collected EMG data were normalized to the percentage of maximum voluntary isometric contraction. The repeated measures ANOVA and paired t-test were used for the statistical analysis of the data. Results: A comparison between mean muscle activation in right arm extension and left leg extension showed that left internal oblique and left transverse abdominis muscles produced greater activation during left leg extension (P<0.05). The comparison of mean muscle activation between right arm extension and the birddog position showed that, except for the right internal oblique, all the muscles produced higher activation in the bird-dog stage (P<0.05). In comparison to the bird-dog stage, the left multifidus showed high activation during left leg extension (P<0.05). Conclusion: The results of this study showed that the activity of all the above-mentioned muscles during quadruped exercise can provide stability, coordination, and smoothness of movements.

Experimental investigation of short-term and longterm corticomotor effects of specifi c neck training, coordination training, and no training. Objective. To determine the effects of different training programs on the motor neurons controlling the neck muscles as well as the effects of training on muscle strength and muscle fatigue, and the correlations between corticomotor control and motor learning. Summary of Background Data. Training is usually recommended for unspecifi c neck pain and consists of neck and upper body coordination, strengthening, and endurance exercises. However, it is unclear which type of training is the most effective. No studies have previously investigated the neural effect of neck training and the possible differential effect of specifi c versus coordination training on corticomotor control. Methods. Transcranial magnetic stimulation and electromyography were used to elicit and monitor motor evoked potentials (MEPs) from the trapezius and thumb muscles before and 30 minu es, 1 hour, and 7 days after training. Parameters measured were MEP amplitude, MEP latency, strength, learning effects, and muscle fatigue. Results. Only specifi c neck training yielded a 67% increase in MEP amplitudes for up to 7 days after training compared with baseline ( P < 0.001). No signifi cant changes were seen after coordination training, no training, and in the within-subject control muscle. The mean muscle strength increased immediately after specifi c neck training from 56.6 to 61 kg ( P < 0.001). No subjective or objective measures of fatigue were observed. Conclusion. Specifi c neck training induced a sustained hyperexcitability of motor neurons controlling the neck muscles compared with coordination training and controls. These fi ndings may prove valuable in the process of developing more effective clinical training programs for unspecifi c neck pain. Copyright © 2013 Lippincott Williams & Wilkins.

According to simulation theories, emotional states affect motor systems. The aim of this study was to compare postural responses assessed by posturography and electromyography when subjects were instructed to imagine themselves in a painful or a nonpainful situation. Methods: Twenty-nine subjects (22.3 +/- 3.7 years) participated in this study. While standing quietly on a posturographic platform, they were instructed to imagine themselves in a painful or non-painful situation. Displacement of the centre of pressure (COP), leg muscle electromyographic activity, heart rate, and electrodermal activity were assessed in response to painful and non-painful situations. Results:The anteroposterior path was shorter (p<0.05) when subjects imagined themselves in a painful situation (M = 148.0 +/- 33.4 mm) compared to a non-painful situation (158.2 +/- 38.7 mm). Higher Tibialis Anterior (TA) activity (RMS-TA = 3.38 +/- 1.95% vs 3.24 +/- 1.85%; p < 0.001) and higher variability of Soleus (SO) activity (variation coefficient of RMS-SO = 13.5 +/- 16.2% vs M = 9.0% +/- 7.2%; p<0.05) were also observed in painful compared to non- painful situations. No significant changes were observed for other physiological data Conclusion: This study demonstrates that simulation of painful situations induces changes in postural control and leg muscle activation compared to non-painful situations, as increased stiffness was demonstrated in response to aversive pictures in accordance with previous results. © 2013 Mouras, Montalan, Morel, Krystkowiak, Ahmaidi and Godefroy.

To establish genotype-phenotype correlations we analyzed clinical and biochemical markers from a database of 190 members in 27 families harboring 10 missense mutations. Individuals were grouped into three categories: symptomatic, presymptomatic carriers and noncarriers. The symptomatic families were further divided into ten groups based on their VCP mutations. There was marked intra and inter-familial variation; and significant genotype-phenotype correlations were difficult to establish because of small numbers. Nevertheless when comparing the two most common mutations, R155C mutation was found to be more severe, with an earlier onset of myopathy and Paget (p=0.03). Survival analysis of all subjects revealed an average life span after diagnosis of myopathy and Paget of 18 and 19years respectively, and after dementia only 6years. R155C had a reduced survival compared to the R155H mutation (p=0.03).We identified amyotrophic lateral sclerosis (ALS) was diagnosed in 13 individuals (8.9%) and Parkinson's disease in five individuals (3%); however, there was no genotypic correlation. This study represents the largest dataset of patients with VCP disease and expands our understanding of the natural history and provides genotype-phenotype correlations in this unique disease. © 2012 John Wiley & Sons A/S.

The traditional method of normalizing myoelectric signals, relative to measured maximum voluntary contractions (MVCs), is susceptible to error and is problematic for evaluating symptomatic low back pain (LBP) patients. Additionally, efforts to circumvent MVCs have not been validated during complex free-dynamic exertions. Therefore, the objective of this study was to develop an MVC-independent biologically-assisted model calibration technique that overcomes the limitations of previous normalization efforts, and to validate this technique over a variety of complex free-dynamic conditions including symmetrical and asymmetrical lifting. The newly developed technique (non-MVC) eliminates the need to collect MVCs by combining gain (maximum strength per unit area) and MVC into a single muscle property (gain ratio) that can be determined during model calibration. Ten subjects (five male, five female) were evaluated to compare gain ratio prediction variability, spinal load predictions, and model fidelity between the new non-MVC and established MVC-based model calibration techniques. The new non-MVC model calibration technique demonstrated at least as low gain ratio prediction variability, similar spinal loads, and similar model fidelity when compared to the MVC-based technique, indicating that it is a valid alternative to traditional MVC-based EMG normalization. Spinal loading for individuals who are unwilling or unable to produce reliable MVCs can now be evaluated. In particular, this technique will be valuable for evaluating symptomatic LBP patients, which may provide significant insight into the underlying nature of the LBP disorder. © 2013 Elsevier Ltd.

During wrist motion, electromyographic activities in the extensor digitorum longus (EDL) and flexor carpi radialis muscles (FCR) were recorded with bipolar electrodes. Degree of wrist range of motion (ROM) was also recorded by electrogoniometry attached to the wrist joint of intact side. Subjects were asked to answer the degree of attainment of phantom limb motion using a visual analog scale (VAS: ranging from 0 (hard) to 10 (easy)).Results:VAS and ROM were significantly increased by utilizing MVF, and the extent of an enhancement of the VAS and wrist ROM was positively correlated (r = 0.72, p<0.05). Although FCR EMG activity also showed significant enhancement by MVF, this was not correlated with the changes of VAS and ROM. Interestingly, while we found negative correlation between EDL EMG activity and wrist ROM, MVF generally affected to be increasing both EDL EMG and ROM.Conclusions:Although there was larger extent of variability in the effect of MVF on phantom limb awareness, MVF has a potential to enhance phantom limb awareness, in case those who has a difficulty for the phantom limb motion. The present result suggests that the motor command to the missing limb can be re-activated by an appropriate therapeutic strategy such as mirror therapy. © 2013 Kawashima et al.

In addition clinical severity and disease progression are greatly variable. We report on a family with 3 siblings characterized by an unusual adult-onset Pompe disease including dysphagia and weakness of tongue, axial and limb-girdle muscles, in association with atypical globular inclusions in muscle fibres. Our study confirms the great clinical and histological variability of adult-onset Pompe disease and further supports the need of careful evaluation of bulbar function in patients affected by this pathology. © 1981 Gaetano Conte Academy.

This case report assesses changes in muscle coordination and kinematics during treadmill running and step ascent in 2 female runners with patellofemoral pain after mirror gait retraining.CASE DESCRIPTION: Two female runners with chronic patellofemoral pain underwent 8 sessions of mirror gait retraining during treadmill running. Subjective measures and hip abductor strength were recorded at baseline and after the retraining phase. Changes in hip mechanics and electromyography data of the gluteus medius during treadmill running and step ascent were also assessed.OUTCOMES: Both runners reported improvements in pain and function that were maintained for at least 3 months. During running, peak contralateral pelvic drop (baseline-postretraining difference: runner 1, 2.6degree less; runner 2, 1.7degree less) and peak hip adduction (baseline-postretraining difference: runner 1, 5.2degree less; runner 2, 6.3degree less) were reduced after retraining. Kinematic reductions accompanied earlier activation of the gluteus medius relative to foot strike (baseline- postretraining difference: runner 1, 12.6 milliseconds earlier; runner 2, 37.3 milliseconds earlier) and longer duration of gluteus medius activity (runner 1, 55.8 milliseconds longer; runner 2, 44.4 milliseconds longer). Runner 1 transferred reduced contralateral pelvic drop to step ascent, whereas runner 2 did not (contralateral pelvic drop baseline-postretraining difference: runner 1, 3.6degree less; runner 2, 1.5degree more; hip adduction baseline-postretraining difference: runner 1, 3.0degree less; runner 2, 0.5degree more). Both runners demonstrated earlier onset of gluteus medius activity during step ascent (baseline-postretraining difference: runner 1, 48.0 milliseconds earlier; runner 2, 28.3 milliseconds earlier), but only runner 1 demonstrated longer activation duration (runner 1, 25.0 milliseconds longer; runner 2, 69.4 milliseconds shorter).DISCUSSION: While changes in hip mechanics and gluteus medius activity during running were consistent with those noted during step ascent for runner 1, runner 2 failed to demonstrate similar consistency between the tasks. Earlier onset and longer duration of gluteus medius activity may have been necessary to alter step mechanics for runner 2. Copyright ©2013 Journal of Orthopaedic & Sports Physical Therapy.

To investigate the association between changes in electromyographic (EMG) signal amplitude and sonographic measures of muscle thickness of 4 abdominal muscles, during 2 clinical tests, in adults with and without lumbopelvic pain. There is a trend in rehabilitation to use ultrasound imaging (USI) to determine the extent of abdominal muscle contraction. However, the literature investigating the relationship between abdominal muscle thickness change and level of activation is inconclusive and has not included clinically relevant tasks. Simultaneous recording from fine-wire EMG and USI was performed for 4 abdominal muscles, in 7 adults with lumbopelvic pain (mean +/- SD age, 29.7 +/- 12.0 years) and 7 adults without lumbopelvic pain (32.0 +/- 10.6 years), during an active straight leg raise (ASLR) test and an abdominal drawing-in maneuver (ADIM). Cross-correlation functions and linear regression analyses were used to describe the relationship between the 2 measures. Analyses of variance were used to compare individuals with and without lumbopelvic pain, with an alpha set at .05. Across all muscles, peak cross-correlation values were low (ASLR, r = 0.28 +/- 0.09; ADIM, r = 0.35 +/- 0.11), and there was large variability in associated time lags (ASLR, tau = 0.69 +/- 2.56 seconds; ADIM, tau = 0.53 +/- 3.75 seconds). Regression analyses did not detect a systematic pattern of association between EMG signal amplitude and USI measurements, and analyses of variance revealed no differences between cohorts. These results suggest a weak relationship between EMG amplitude and abdominal muscle thickness change measured with USI during the ADIM and ASLR, and raise questions about thickness change derived from USI as a measure of muscular activity for the abdominal musculature.

Although the control of precise three-dimensional forces is essential for the performance of functional tasks, current evidence of pain effects in force variability is limited to single-directional assessments of contractions at moderate force levels. This study assessed the effects of experimental knee joint pain in the three-dimensional force variability during isometric knee extensions at a wide range of target forces (2.5-80 % of maximal voluntary contraction, MVC). Fifteen healthy subjects performed contractions before, immediately following, and after injections of hypertonic (painful) or isotonic (control) saline into the infrapatellar fat pad. Pain intensity was measured on a 10-cm visual analogue scale. Force magnitude, direction, and variability were assessed using a six-axis force sensor while activity of quadriceps and hamstring muscles was recorded by surface electromyography. Significant correlation was found between tangential force displacements and variability of quadriceps muscle activity. Experimental knee pain increased the variability of the task-related force component at all force levels, while variability of tangential force components increased at low forces (<=5 % of MVC). The mean quadriceps activity decreased during painful contractions only at 80 % of MVC. Pain adaptations underlying increased force variability at low contraction levels probably involve heterogeneous reorganization of muscle activity, which could not be detected by surface electrodes. These findings indicate a less efficient motor strategy during knee joint pain, suggesting that pain relief may enhance training for the control of smooth forces by knee pain patients. © 2012 Springer-Verlag.

However, postoperative recovery may be associated with adverse symptoms of pain, urinary and defecatory dysfunction. Pelvic floor physical therapy (PFPT) is often used as a treatment and has been shown to improve muscular function at 12 weeks following repair. However, we are lacking information regarding sustained benefits of this modality. Methods: This was a randomized controlled trial of patients undergoing vaginal reconstructive surgery. Treated subjects were assigned to standardized PFPT sessions and physician encounters for 12 weeks postoperatively. Control subjects underwent a physician encounter alone at all the same points. Both groups completed POP-Q exams, pelvic floor surface electromyography (EMG), voiding diaries and several validated questionnaires at baseline, 12 and 24 weeks post surgery: the World Health Organization Quality Of Life-BREF (WHOQOL-BREF), PFDI-20, PFIQ-7, General Health Survey (SF-12), Female Sexual Function Index (FSFI) and PISQ-12. Our a priori sample size calculation set a recruitment goal of 50 subjects. Results: Fifty-seven women were recruited. Forty-nine completed the study: 24 PFPT, 25 controls. The mean age was 58, and demographics were similar at baseline. When assessed at 12 weeks postoperatively, surface EMG showed significant improvements in resting measures for the PFPT group compared to controls and better coordination of the pelvic floor. However, at 6 months following surgery these changes were no longer noted; almost all parameters returned to baseline values suggesting lack of sustained benefit. Regarding the validated questionnaires, large improvements were noted for the entire sample at 12 weeks with no detectable distinction based on treatment arm. At 24 weeks, the majority of these scores remained stable and significantly better than baseline. However, further improvements were documented from 12 to 24 weeks in the PFDI (p=0.04) and PFIQ (p=0.018), corresponding with continued enhancement in urinary scales for these indices. Specifically, the UDI-6 and IIQ-7 showed ongoing improvements between 3 and 6 months (p=0.05 and p=0.007, respectively). Additionally, sexual function measures increased significantly between 12 and 24 weeks, particularly FSFI domains of satisfaction (p=0.016), arousal (p=0.02) and orgasm (p=0.035). Nevertheless, there was no difference noted based on treatment with PFPT. Conclusions: Reassuringly, quality of life improves dramatically in all subjects following vaginal reconstructive surgery, with further benefit to bladder symptoms and sexual function between 3 and 6 months. While standardized PFPT resulted in superior EMG measurements at 12 weeks, these reverted when PFPT sessions ceased. Although the role for routine use of PFPT after vaginal surgery remains unclear, advantages may be more apparent with ongoing treatment. Further research of more intensive regimens of PFPT may improve awareness regarding a role for this modality in all subjects.

Most surgeons allow their patients to start running 5 to 6 month after the operation. Is this period long enough to allow sufficient hip muscle recuperation? Methods: Twelve patients between 55 and 65 years with a mean follow up of 4 years (6 months to 8 years) after hip arthroplasty were included in this study. All had been practicing running regularly before having developed osteoarthritis and all had continued after the operation. Spatio-temporale parameters were extracted at different velocity with 3-dimensional accelerometers and gyroscopes on the feet. Simultaneously the muscle activity of the gluteus maximus, the gluteus medius and the rectus femoris of both sides were recorded with EMG sensors. The parameters were validated with 4 healthy control subjects. Results: All participants had started again to run regularly six months after the operation. Six to twelve months after the operation, the EMG signal shows a high variability and the eccentric contraction of the hip muscles were not clearly perceivable. At 12 months, the EMG-signal of the gluteus maximus becomes progressively more regular and between 1 and 2 year, the one of the gluteus medius. 2 to 3 years postoperative the peaks of the eccentric contraction of the three hip muscles are again attained simultaneously. Conclusion: The simultaneous measurement of the EMG of the three main hip muscles allows to detect the stepwise normalization of their function after hip arthroplasty. A well coordinated eccentric contraction of the extensor muscles reduces the transmission of excessive forces up to the hip joint during running. An intensive reinforcement of the hip muscles is mandatory after hip arthroplasty. Before starting to run again, at least the eccentric contraction of the gluteus maximus should be normalized.

This study examined the effect of experimentally induced muscle pain on the kinematic performance and motor control of the neck region. Methods. Fourteen healthy individuals (24.5+/-2.4 yrs) performed multi-directional aiming movements of their head and neck in the vertical plane. Nine targets (base +8 directions) were placed in a circle on a wall positioned 1 m in front of the subject and he/she was asked to follow the circular trajectory (pi/4 apart, with an offset of pi/8, 1 m radius), returning each time to the base target. Subjects wore a custom-made helmet equipped with a symmetrically distributed weight and two laser pointers. The task consisted of moving their head and neck to aim the laser at the targets whilst seated. The task was repeated four times: baseline, after the injection of non-painful isotonic or painful hypertonic saline solution (randomized), and ten minutes after the reported end of pain (post condition). The saline was injected into the right splenius capitis muscle. Participants were asked to report their level of pain intensity between 0 and 10 on a numerical rating scale (NRS). Kinematic data from the helmet was used to detect the movement of subject's head. Surface EMG signals were recorded from the Sternohyoid, Sternocleidomastoid, Anterior Scalene, Splenius Capitis, Upper Trapezius, and Lower Trapezius muscles bilaterally. The RMS value of the EMG was estimated for each muscle, trial, direction and condition. Results. The hypertonic saline injection elicited a painful sensation (NRS: 4.4+/-1.3) which lasted 5.8+/-1.8 min. Despite the reported pain, all subjects were able to accomplish the required task with no major errors. The maximal speed reached by the subjects, distance traveled and time to reach the peak speed didn't change across conditions. A decreased muscular activation was observed for the injected muscle and its contralateral homologous. Inhibition was more pronounced in specific directions (downards ipsilateral and contralateral, and upward contralateral). The surrounding muscles modulated their activity in a flexible, task-dependent way. Local excitation of nociceptive afferents in one neck muscle induced a dynamic reorganization of the coordination among neck muscles but did not affect the mechanical output. Conclusion. These observations suggest that the Central Nervous system is able to modulate and re-arrange the activity of muscles in a goal-oriented manner during acute experimentally induced muscle pain.

Focal injections of Botulinum toxin (BoNT-A) into the affected muscles is a common option for spasticity management. This approach has been shown to reduce spasticity and pain however, the evidence for improved functional outcomes using this management strategy remains equivocal. Contributing to this may be the type of adjunctive therapy used with the injections or the selection of outcome measures. The purpose of this study is to compare the effects of a combined BoNT-A/ upper limb movement training approach versus a combined BoNT-A/functional rehabilitation approach on electrophysiological, clinical and behavioural outcomes in stroke survivors with spasticity in the upper limb. Methods: In this randomized single-blind crossover design study, participants are randomized to 10 weeks/3x week of movement training followed by a 12 week washout or 10 weeks/3x week of functional neurorehabilitation followed by a 12 week washout. Participants then cross over to the alternate therapy. Assessments are done at baseline then at 4, 8 and 10 weeks after the administration of BoNT-A. Primary electrophysiological outcomes are surface EMG amplitude and timing, EEG amplitude and frequency and single motor unit discharge rate and variability. Secondary outcomes include clinical (MAS, CMSA) and behavioural (kinetics, kinematics) measures. Results: To date, 11 participants have been enrolled in the study (mean age = 58.3}15.9 years, 7 male). The median elbow MAS score at intake is 1+ and the median CMSA hand and arm stages are 2 and 2, respectively. Rate of recruitment is 52.4% and study adherence is 100%. Conclusions: This clinical trial aims to identify a neurorehabilitation intervention that, when coupled with BoNT-A injections, enhances recovery in stroke survivors with upper limb spasticity. This will contribute to the growing body of work probing the capacity for functional recovery in individuals with spasticity after stroke.

Background: Profession of dental technician is demanding on exact hand work in manufacturing of stomatologic products- dental bridges, crowns, protheses. The work is associated with eye-hand coordination, noise, vibration, dominant hand overload and stress. After nearly complete privatization of dental laboratories in the beginning of 1990's the working hours of technicians extended while the drilling machines stayed relatively old, with overload and high intensity of vibration. Methods: A retrospective study with analysis of patients in our database of EMG laboratory and botulinum toxin outpatient clinic for dental technicians with dystonia. Results: There are 5 dental technician, all women, treated in our clinic with botulinum toxin. Three are treated for cervical dystonia. The first symptoms occurred in nearly same age - 46-48 years, after 27-30 years of work in dental laboratory. They retired after 4-7 years of treatment with botulinum toxin. They received botulinum toxin A 3-4 times in a year, 220-260 units. In 56 year old dental technician oromandibular dystonia occurred, with intensive pain. She retired after further 4 years. Masticatory muscles are infiltrated 4 times in a year, 140 units. In 41 year woman a professional dystonia of right hand developed. The "writer's cramp" occured during the drilling, later during writing, cooking and then other house chores. She tried to work with her left hand, but dystonia of left hand developed very early. After 1 year botulinum toxin therapy she had to retire and completely stopped laboratory work. Conclusions: The work of dental technician is demanding on strength of dominant hand, accuracy, precise visual control, with exposition to vibration and stress. That's why dental technicians are prone to develop different forms of dystonia). Though the technicians had to prematurely retire, treatment of dystonia with botulinum toxin is successful.

He was the product of a normal pregnancy, born at term via C-section and met all of his early milestones and his mother states that he was a more "relaxed" infant than his siblings. At age 2, the family noted less physical activity compared to his siblings; he was less interested in sports and preferred to be carried. Then he started having difficulty walking and would easily fatigue and experience leg pain. He then began to fall frequently and would have difficulty standing and climbing the stairs. He cannot smile, although his father cannot smile either but is otherwise asymptomatic. He denies sensory problems, bulbar weakness or cognitive changes. His symptoms have progressed slowly; since age 9, he has a wheelchair for long-distances. At age 10, he was diagnosed with type 1 diabetes. No family history of neuromuscular disease. Exam demonstrated weakness in his face, neck muscles and proximal > distal extremities. Reflexes are absent throughout. Sensation and coordination are intact. He has a slow, wide-based and waddling gait and rise from the floor with a Gower's maneuver. His laboratory evaluation including CK was unremarkable. EMG/NCS demonstrated mild non-specific changes including polyphasic motor unit potentials. A muscle biopsy demonstrated clusters of small type 1 fibers with internal nucleation and occasional central lucency on NADH. A number of genetic tests were performed, including MTM1, DNM2 and BIN1, which were negative. DNA sequencing of the RYR1 gene demonstrated a compound heterozygous state with two separate exon 79 mutations: c.11315G>A and c.11320delG. Along with other recent case reports, this case illustrates the phenotypic and pathological variability in patients with RYR1 mutations.

Phenotypic variability in this family was shown with autosomal recessive inheritance pattern. We present a second family with this infrequent mutation and we analyze the clinical presentation. Methods: The index case and her affected sister were followed from the 199's. Her apparently non-consanguineous parents were explored as well as two brothers and another sister, none of which present clinical myotonia. A EMG study of both parents was carried out and no signs of myotonic discharges or myopathic alterations were registered. The clinical chart of the two affected brothers were analysed retrospectively. Results: Both patients have grip and percussion myotonia with calf hypertrophy. Proximal weakness affecting in different degrees and with a progressive course was also observed. The weakness improved after exercise, was worse after prolonged rest and varied significantly in both patients. Muscle pain was not a significant problem, however a progressive chronic fatigue developed over the years. The EMG showed typical myotonic discharges without myopathic alterations. A muscle biopsy in one patient only showed atrophy of type II muscle fibres. The genetic screening formutations in theCLCN1 gene showed a c.742A>T transition in exon 6 in both patients resulting in a lysine to a stop-codon substitution at position 248 of the protein (K248X). Conclusion: In our family we observed a mild pattern of affectation with a mild progression, similar to the Brazilian family previously reported, despite a mutation that predicts an early truncation of the CLCN1 gene. We also confirm the autosomal recessive inheritance pattern of this gene mutation. Proximal weakness of different degrees was also observed, which strikingly worsened with rest and improved with exercise and progressive chronic fatigue were notable features previously not reported in these mutations.

All participants used a portable single-channel EMG device (Medotech A/S) for four nights. There was no significant difference in EMG activity between craniofacial pain (24.5 +/- 17.9 events/hr) and no painful conditions (19.7 +/- 14.5), or between TTH (20.8 +/- 15.0) and healthy control individuals (15.2 +/- 11.6, p >.050). There were positive correlations between EMG activity and number of painful muscles (r = 0.188; p = 0.044), characteristic pain intensity (r = 0.187; p = 0.046), McGill Pain Questionnaire (r = 0.251; p = 0.008), and depression scores (r = 0.291; p = 0.002). Patients with painful conditions had significantly higher night-to-night variability compared with pain-free individuals (p < 0.050). This short-term observational study suggests that there are no major differences between patients with different craniofacial pain conditions and pain-free individuals in terms of jaw-muscle EMG activity recorded with a single-channel EMG device during sleep. However, some associations may exist between the level of EMG activity and various parameters of craniofacial pain. Longitudinal studies are warranted to further explore the relationship between sleep bruxism and craniofacial pain. © 2012 International & American Associations for Dental Research.

Muscle pain was induced by infusion of hypertonic saline into the abductor digiti minimi muscle of 11 healthy men. Intramuscular EMG signals were recorded from the same muscle during four isometric contractions of 60-s duration at 10% of the maximal force [maximal voluntary contraction (MVC)] performed before injection (baseline), after injection of isotonic (control) or hypertonic saline (pain), and 15 min after pain was no longer reported. Each contraction was preceded by three 3-s ramp contractions from 0% to 10% MVC. The lowfrequency oscillations of motor unit spike trains were analyzed by the first principal component of the low-pass filtered spike trains [first common component (FCC)], which represents the effective neural drive to the muscle. Pain decreased the accuracy of task performance [coefficient of variation (CoV) for force: baseline, 2.8 +/- 1.8%, pain, 3.9 +/- 1.8%; P < 0.05] and reduced motor unit discharge rates [11.6 +/- 2.3 pulses per second (pps) vs. 10.7 +/- 1.7 pps; P < 0.05]. Motor unit recruitment thresholds (2.2 +/- 1.2% MVC vs. 2.4 +/- 1.6% MVC), interspike interval variability (18.4 +/- 4.9% vs. 19.1 +/- 5.4%), strength of motor unit short-term synchronization [common input strength (CIS) 1.02 +/- 0.44 vs. 0.83 +/- 0.22], and strength of common drive (0.47 +/- 0.08 vs. 0.47 +/- 0.06) did not change across conditions. The FCC signal was correlated with force (R = 0.45 +/- 0.06), and the CoV for FCC increased in the painful condition (5.69 +/- 1.29% vs. 7.83 +/- 2.61%; P < 0.05). These results indicate that nociceptive stimulation increased the low-frequency variability in synaptic input to motoneurons.

A randomized controlled trial. Objective. To compare changes in self-rated disability, pain, and anticipatory postural adjustments between specific trunk exercise and general exercise in patients with chronic low back pain. Summary of Background Data. Chronic low back pain is associated with altered motor control of the trunk muscles. The best exercise to address altered motor control is unclear. Methods. Sixty-four patients with chronic low back pain were randomly assigned to a specific trunk exercise group (SEG) that included skilled cognitive activation of the trunk muscles in addition to a number of other best practice exercises, whereas the general exercise group performed only seated cycling exercise. The training program lasted for 8 weeks. Self-rated disability and pain scores were collected before and after the training period. Electromyographic activity of various trunk muscles was recorded during performance of a rapid shoulder flexion task before and after training. Muscle onsets were calculated, and the latency time (in ms) between the onset of each trunk muscle and the anterior deltoid formed the basis of the motor control analysis. Results. After training, disability was significantly lower in the SEG (d = 0.62, P = 0.018). Pain was reduced in both groups after training (P < 0.05), but was lower for the SEG (P < 0.05). Despite the general exercise group performing no specific trunk exercise, similar changes in trunk muscle onsets were observed in both groups after training. Conclusion. SEG elicited significant reductions in self-rated disability and pain, whereas similar between-group changes in trunk muscle onsets were observed. The motor control adaptation seems to reflect a strategy of improved coordination between the trunk muscles with the unilateral shoulder movement. Trunk muscle onsets during rapid limb movement do not seem to be a valid mechanism of action for specific trunk exercise rehabilitation programs. Copyright © 2012 Lippincott Williams & Wilkins.

We have shown that asymptomatic people performing repetitive upper limb tasks display signs of shoulder fatigue and of whole-body compensatory strategies. However, the role played by the proprioceptive system in the production of these compensatory strategies has not been studied. A group of asymptomatic adults (n = 18) performed a repetitive pointing task at shoulder height to fatigue. Before and after fatigue, they performed two position sense tasks, eyes closed: A single-joint task where they abducted their shoulder to the perceived horizontal and a multi-joint task, where they stood and placed their finger at the perceived location of a target in front of them at shoulder height. After fatigue, subjects made larger shoulder errors by raising their elbow higher above the horizontal (~+1.3 cm) than before fatigue; however, their finger position accuracy was not changed, despite all subjects performing the movement in less time (~-0.18 s) while fatigued. There were no gender differences in shoulder or finger position accuracy before or after fatigue; however, there were gender differences in the perceived finger-target location and in the temporal characteristics of the finger movement toward the target. Results suggest that healthy individuals are able to develop strategies to compensate for fatigue-induced deficits at one joint to maintain the endpoint accuracy of a multi-joint task constant. Gender differences in movement strategies and perception of endpoint location may play parts in the previously reported gender differences in workrelated neck/shoulder symptoms. © Springer-Verlag 2011.

The patient was a 36-year-old woman who was diagnosed with NMO and had difficulties in walking. VS was applied to the lower limb muscles on the left, more spastic, side with an ordinary vibrator. The performance of standing up and walking improved with VS. Even with improved performance after VS, the amount of surface EMG of the lower limbs did not increase as a whole, but the EMG patterns among the lower leg muscles changed remarkably. VS produced reciprocity within antagonistic muscles. Variability of EMG amplitudes decreased remarkably during the walking cycle, not only on the vibrated side, but also on the non-vibrated side. The effect lasted longer than several dozen minutes after the cessation of VS. We conjectured that central pattern generator (CPG) and neuronal plasticity were the result of VS.

The clinical evaluations were completed both before and after the treatment. Electromyographic (EMG) data was collected and recorded on the day the splint was inserted (visit 1), after one week (visit 2) and after five weeks of treatment (visit 3). The control group consisted of 15 asymptomatic subjects, according to the same diagnostic criteria (RDC/TMD), who were submitted to the same evaluations with the same interval periods as the treatment group. Immediately after splint adjustment, masseter muscle symmetry and total muscular activity were significantly different with than without the splint (p < 0.05), showing an increased neuromuscular coordination. After treatment, significant variations (p < .05) were found in mouth opening and in pain remission. There were no significant differences among the three sessions, either with or without the splint. There were significant differences between the TMD and control groups for all analyzed indices of muscular symmetry, activity and torque, with the exception of total muscular activity. The use of the splint promoted balance of the EMG activities during its use, relieving symptoms. EMG parameters identified neuromuscular imbalance, and allowed an objective analysis of different phases of TMD treatment, differentiating individuals with TMD from the asymptomatic subjects.

More variation in biomechanical exposure is often suggested as an effective intervention in such settings. Since increasing variation using extrinsic methods like job rotation may not always be possible in an industrial context, the intrinsic variability of the motor system may offer an alternative opportunity to increase variation. Motor variability refers to the natural variation in postures, movements and muscle activity observed to different extents in all tasks. The current review discusses research appearing in motor control, sports sciences and occupational biomechanics literature to answer whether motor variability is important to consider in an occupational context, and if yes, whether it can be manipulated by training the worker or changing the working conditions so as to increase biomechanical variation without jeopardizing production. The review concludes that motor variability is, indeed, a relevant issue in occupational health and performance and suggests a number of key issues for further research. © 2012 Elsevier Ltd.

Three entities associated with deficiency of CPT II are known: the perinatal, the infantile and the adult form. The perinatal disease is the most severe form and is invariably fatal. On the other hand, the adult CPT II clinical phenotype is benign and requires additional external triggers such as highintensity exercise to provoke myopathic symptoms. We report a case of adult CPT II deficiency presenting with the subtle symptoms of myopathy. A 32-year-old man was admitted to the hospital complaining of muscle pain after exercise. Athletic appearance drew attention, because the patient denied practicing sport. Neurological examination revealed marked tiredness during the single-leg hop test without other abnormalities. Electromyography (EMG) and serum biochemistry were not typical for myopathy. Routine histopathological examination did not reveal any abnormalities of structure of muscle fibers. Diagnosis was established after ultrastructural and biochemical analysis which revealed changes typical for CPT II deficiency.

The CRGT is a paced and timed, repetitive reach and grasp task that was designed to monitor both kinematics and electromyography of the upper limb. Patients (n = 9) with moderate to severe neck pain were compared with healthy controls (n = 7). Activities from 10 muscles of the upper limb were acquired during performance of the CRGT and processed to render both temporal/spatial and amplitude indices. Cross- and Pearson correlations of selected muscle pairs were calculated. Comparisons were conducted using nonparametric statistics. All participants completed the CRGT but only patients self-reported pain after performance (visual analog scale rating of 3.9 +/- 2.7 on the affected side). Modulation of activity was observed for posture (sitting vs. standing, P = 0.034) and side (affected/nondominant vs. unaffected) for controls (P = 0.005). The patient group did not demonstrate significant differences between these dependent variables. Neuromuscular strategies exhibited by patients during reaching did not alter significantly with variation in side and posture, as they did with controls, indicating the lack of a capacity to modulate muscle activity appropriate to the task. This is a significant consequence of the chronic pain experienced by patients with mechanical neck disorder and may underlie the upper limb disability reported in this patient population. © 2012 by Begell House, Inc.

Methods: Thirteen Canadian physicians assembled to develop and analyze results of a cross-sectional electronic survey, sent to 50 physicians across Canada. Results: Seventy-eight percent (39/50) of physicians completed the survey. The most frequently identified assessment tools were Gross Motor Function Classification System, Modified Tardieu Scale and neurological examination. Goal-setting tools were infrequently utilized. Common indications for BoNT-A injections and the muscles injected were identified. Significant variability was identified in using BoNT-A for hip displacement associated with hypertonia. The most frequent adverse event reported was localized weakness; 54% reporting this "occasionally" and 15% "frequently". Generalized weakness, fatigue, ptosis, diplopia, dysphagia, aspiration, respiratory distress, dysphonia and urinary incontinence were reported rarely or never. For dosage, 52% identified 16 Units/kg body weight of Botox as maximum. A majority (64%) reported a maximum 400 Units for injection at one time. For localization, electrical stimulation and ultrasound were used infrequently (38% and 19% respectively). Distraction was the most frequently used pain-management technique (64%). Conclusions: Canadian physicians generally adhere to international best practices when using BoNT-A to treat paediatric hypertonia. Two knowledge-translation opportunities were identified: use of individualized goal setting prior to BoNT-A and enhancing localization techniques. Physicians reported a good safety profile of BoNT-A in children.

MH - adult MH - article MH - *body posture MH - clinical trial MH - electromyography MH - female MH - human MH - *low back pain MH - male MH - methodology MH - pathophysiology AB - The cost of the medical treatment of low back pain (LBP) was estimated to be $24 billion in the early 90s. Also, 80% of the LBP is estimated to be due to poor or inappropriate posture. The ultimate goal of the project is to develop a surface electromyography (sEMG)-based device that could be used to prevent and treat LBP by postural re-education or simply for on-the-spot sEMG feedback. In this paper we present the results and conclusions of a feasibility study for sEMG-based poor posture classifier. The results show that a s-EMG based poor posture classifier could be possible. The sensitivity for the best linear classifier model was 72% and the specificity was 78%. The same signal feature returned very different results from one participant to another. This inter-subject variability could be due to different muscular activation patterns during posture correction.

More variation in biomechanical exposure is often suggested as an effective intervention in such settings. While increasing variation using extrinsic methods like job rotation may not always be possible in an industrial context, the intrinsic variability of the motor system may offer an alternative opportunity to increase variation. Motor variability (MV) refers to the natural variation in postures, movements and muscle activity observed to different extents in all tasks. The current review explores the state of the art in MV research from motor control, sports and occupational biomechanics literature to answer whether MV is important to consider in an occupational context, and if yes, whether this literature stimulates further studies to test if MV can be manipulated as a deliberate intervention for increasing biomechanical variation without jeopardizing production.

MH - adult MH - article MH - *body posture MH - clinical trial MH - electromyography MH - female MH - human MH - *low back pain MH - male MH - methodology MH - pathophysiology AB - The cost of the medical treatment of low back pain (LBP) was estimated to be $24 billion in the early 90s. Also, 80% of the LBP is estimated to be due to poor or inappropriate posture. The ultimate goal of the project is to develop a surface electromyography (sEMG)-based device that could be used to prevent and treat LBP by postural re-education or simply for on-the-spot sEMG feedback. In this paper we present the results and conclusions of a feasibility study for sEMG-based poor posture classifier. The results show that a s-EMG based poor posture classifier could be possible. The sensitivity for the best linear classifier model was 72% and the specificity was 78%. The same signal feature returned very different results from one participant to another. This inter-subject variability could be due to different muscular activation patterns during posture correction.

Objectives: To assess scapular kinematics and electromyographic signal amplitude of the shoulder musculature, before and after thoracic spine manipulation (TSM) in subjects with rotator cuff tendinopathy (RCT). Changes in range of motion, pain, and function were also assessed. Background: There are various treatment techniques for RCT. Recent studies suggest that TSM may be a useful component in the management of pain and dysfunction associated with RCT. Methods: Thirty subjects between 18 and 45 years of age, who showed signs of RCT, participated in this study. Changes in scapular kinematics and muscle activity, as well as changes in shoulder pain and function, were assessed pre-TSM and post-TSM using paired t tests and repeated-measures analyses of variance. Results: TSM did not lead to changes in range of motion or scapular kinematics, with the exception of a small decrease in scapular upward rotation (P = .05). The only change in muscle activity was a small but significant increase in middle trapezius activity (P = .03). After TSM, subjects demonstrated decreased pain during performance of the Jobe empty-can (mean +/- SD change, 2.6 +/- 1.1), Neer (2.6 +/- 1.3), and Hawkins-Kennedy (2.8 +/- 1.3) tests (all, P<.001). Subjects also reported decreased pain with shoulder flexion (mean +/- SD change, 2.0 +/- 1.5; P<.001) and improved shoulder function (force production, 2.5 +/- 1.4 kg; Penn Shoulder Score, 7.7 +/- 9.4; sports/performing arts module of the Disabilities of the Arm, Shoulder and Hand questionnaire, 16.4 +/- 13.2) (all, P<.001). Conclusion: Immediate improvements in shoulder pain and function post-TSM are not likely explained by alterations in scapular kinematics or shoulder muscle activity. For people with pain associated with RCT, TSM may be an effective component of their treatment plan to improve pain and function. However, further randomized controlled studies are necessary to better validate this treatment approach. Copyright © 2012 Journal of Orthopaedic & Sports Physical Therapy.

Eleven healthy men (25.2 +/- 3.0 years of age) and five healthy women (23.0 +/- 3.7 years of age) performed a standardized mental stress task, the Paced Auditory Serial Addition Task (PASAT). Autonomic function, such as heart rate variability (HRV), and haemodynamic changes were recorded simultaneously. The success rate of the PASAT decreased with increased pace and duration. Low-frequency (5.8 +/- 1.1 ms2) and high-frequency (5.3 +/- 0.6 ms2) components of HRV decreased during the PASAT (to 5.0 +/- 0.9 ms2 and 4.6 +/- 1.1 ms2, respectively) as an indication of acute stress. Oxygenated haemoglobin in the masseter muscle (14.6 +/- 2.2 104 units mm-3) remained at an elevated level during the PASAT (15.5 +/- 2.5 104units mm-3), whereas deoxygenated haemoglobin (7.8 +/- 2.3 104 units mm-3) showed a consistent decrease (to 6.8 +/- 2.1 104 units mm-3). Total haemoglobin and jaw-muscle electromyographic (EMG) activity did not change during the PASAT. Thus, PASAT-induced mental stress changed the parasympathetic/sympathetic balance of the heart and had an acute influence on jaw-muscle haemodynamics, but not on jaw-muscle EMG activity. This non-invasive experimental set-up can be applied to study the effects of repeated or longer-lasting mental stress in order to further the understanding of pathophysiological mechanisms in craniofacial pain conditions. © 2012 Eur J Oral Sci.

However, the relationship of this neuromotor impairment to recurrent pain episodes is unknown. To assess coordination while minimizing the confounding influences of pain we characterized automatic postural responses to multi-directional support surface translations in individuals with a history of LBP who were not in an active episode of their pain. Twenty subjects with and 21 subjects without non-specific LBP stood on a platform that was translated unexpectedly in 12 directions. Net joint torques of the ankles, knees, hips, and trunk in the frontal and sagittal planes as well as surface electromyographs of 12 lower leg and trunk muscles were compared across perturbation directions to determine if individuals with LBP responded using a trunk stiffening strategy. Individuals with LBP demonstrated reduced peak trunk torques, and enhanced activation of the trunk and ankle muscle responses following perturbations. These results suggest that individuals with LBP use a strategy of trunk stiffening achieved through co-activation of trunk musculature, aided by enhanced distal responses, to respond to unexpected support surface perturbations. Notably, these neuromotor alterations persisted between active pain periods and could represent either movement patterns that have developed in response to pain or could reflect underlying impairments that may contribute to recurrent episodes of LBP. © 2011 Elsevier Ltd.

Prospective, cases series study. Sixteen healthy volunteers without contraindications for cervical traction. Subjects received mechanical intermittent cervical traction in a sitting position under two traction forces (10% and 20% of total body weight). Electrocardiographic and neck surface electromyographic signals were recorded and analysed from 3 5-min periods (before, during and after traction). Subjective symptoms, heart rate and heart rate variability parameters, including standard deviation of all normal-to-normal beat intervals, very low-frequency power, low-frequency power, high-frequency power, multiscale entropy, slope of multiscale entropy, and root mean square value of electromyography amplitude were statistically compared. This pilot study showed that using 10% body weight traction force was more comfortable than using 20% body weight. Only subtle perturbation was noted in the autonomic system when using 20% body weight traction force. The response pattern of heart rate variability analysis in this pilot study provides some early information about individual discomfort in cervical traction. The autonomic modulation and the safety of cervical traction with other modality settings or in patients with neck pain require further study.

Many studies have focused on decreasing PLP with mirror therapy, yet few have examined the same visual ameliorating effect with a virtual or prosthetic limb. Our study addresses the following key questions: (1) does PLP decrease through observation of a 3D limb in a virtual integration environment (VIE) and (2) can consistent surface electromyography (sEMG) signals from the VIE drive an advanced modular prosthetic limb (MPL)? Recorded signals from the residual limb were correlated to the desired motion of the phantom limb, and changes in PLP were scored during each VIE session. Preliminary results show an overall reduction in PLP and a trend toward improvement in signal-to-motion accuracy over time. These signals allowed MPL users to perform a wide range of hand motions.

The present study used a cross-over design to assess the effects of muscle pain on the stability of multidirectional (taskrelated and tangential) forces during sustained dorsiflexions, elbow flexions, knee extensions, and plantarflexions. Fifteen healthy subjects performed series of isometric contractions (13-s duration, 2.5, 20, 50, 70% of maximal voluntary force) before, during, and after experimental muscle pain. Three-dimensional force magnitude, angle and variability were measured while the task-related force was provided as feedback to the subjects. Surface electromyography was recorded from agonist and antagonist muscles. Pain was induced in agonist muscles by intramuscular injections of hypertonic (6%) saline with isotonic (0.9%) saline injections as control. The pain intensity was assessed on an electronic visual analogue scale. Experimental muscle pain elicited larger ranges of force angle during knee extensions and plantarflexions (P < 0.03) and higher normalized fluctuations of task-related (P < 0.02) and tangential forces (P < 0.03) compared with control assessments across force levels, while the mean force magnitudes, mean force angle and the level of muscle activity were non-significantly affected by pain. Increased multidirectional force fluctuations probably resulted from multiple mechanisms that, acting together, balanced the mean surface electromyography.

We report a 40-year-old woman with 1-year history of pain and paresthesia in the left shoulder and arm that was clinically interpreted as brachial plexus neuritis. Electromyography revealed both myopathic and neuropathic abnormalities, and because of the myopathic changes a muscle biopsy was performed. The typical morphologic features of dynamin-2 CNM with additional numerous necklace fibres were found in the muscle biopsy. Sequencing of the DNM2 and MTM1 genes revealed a not previously described heterozygous missense mutation in exon 18 of DNM2 leading to replacement of highly conserved Proline in position 647 by Arginine. The muscle symptoms have not progressed during the two-year follow-up, but the patient has developed bilateral subtle lens opacities. Necklace fibres were originally described as fibres that had usually a small diameter and internalized nuclei aligned in a basophilic ring at a few micrometers beneath the sarcolemma. They were described in association with myopathies caused by MTM1 mutations, and similar but not identical fibres have also been reported in a case of DNM2 associated CNM. Our findings support the concept that necklace fibres are not specific but indicate common pathogenic mechanisms in DNM2 and MTM1 associated CNM. This case report expands the clinical, morphological and molecular genetic variability of DNM2 associated CNM.

Overuse injury has been associated with decreased movement variability, and Australian Football is a game with highly repetitive movements such as cutting and running that have been linked with groin injury (Davies, Clarke, Gilmore, Wotherspoon,&Connell, 2009; Hiti, 2011). Therefore, this study aimed to determine whether movement variability during an unanticipated cut task differed between athletes with and without a history of groin injury. Methods: Seventeen male Australian Football players either with a history (HISTORY; n = 7) or without a history (CONTROL; n = 10) of a groin injury performed 10 successful trials of an unanticipated cut task with a defensive opponent. During each trial, the participants' ground reaction forces three-dimensional kinematics, and surface electromyography were recorded with additional inclusion of an isokinetic hip muscular strength test. Results: Participants with a HISTORY displayed decreased movement variability within the kinematics of the ankle, knee and T12-L1 joints, and ankle, knee and hip joint moments compared to the CONTROL group. Nevertheless, the HISTORY group displayed increased movement variability within the kinematics of the hip and L5-S1 joints, increased body mass, and decreased hip adduction muscular strength compared to CONTROL group. Conclusion: Increased movement variability within lumbopelvic kinematics and decreased hip adduction muscular strength in participants with a history of groin injury support current groin rehabilitation methods of addressing lumbopelvic instability. Our results also highlighted decreased movement variability within the ankle, knee, L5-S1 and T12-L1, which clearly identifies the need for clinical management of the lower limb and thoracic segment to improve functional movement patterns.

The underlying mechanisms for certain movement behaviour are often unknown, and it may be hard to identify which specific sensory input that drives the movement and what processes that determine whether the outcome is going to be successful or not. Deficits in neuromuscular coordination may lead to pain, or pain may cause changes in movement patterns. Some of these patterns will preside even if the pain goes away. This lecture will address how to capture and monitor human movement strategies and muscular activation patterns in a movement analysis laboratory by recording kinematic (movements), kinetic (forces) and electromyographic (EMG; signals from muscles) data. These techniques provide detailed information which cannot be obtained by simple observation by the human eye. Such data reflect how the brain controls the movements, and help to increase our understanding of sensorimotor control. The usefulness of this type of methodology in rehabilitation to monitor changes or progress over time, and in research will be discussed. Examples will be given for various types of test conditions and movement tasks such as grasping, balance performance and other types of coordination in healthy subjects and in subjects with various clinical diagnoses like patellofemoral pain, reconstructed or conservatively treated anterior cruciate ligament (ACL) injury and osteoarthritis.

He has peripheral vascular disease and in 2007 had a re-vascularization procedure, followed by below knee amputation. He was having constant pain in distal stump and he has tried physical therapy, prosthesis and narcotic medications. He underwent at knee amputation in November 2009. The AKA revision was done in January 2010. His residual limb is long and is tender to palpation at the distal end. Acupuncture was done because he had ongoing pain in the residual distal stump. Program Description: He had tried other conservative modalities prior to acupuncture trial. Prior to initiation of acupuncture treatments, patient reported pain at 8/10 on the Visual Analog Pain Scale (VAS). Biofeedback measures were done to assess heart rate (HR) variability, abdominal breathing, EMG muscle tension and skin conductance during rest, stressor and recovery. VAS was also documented before and after treatment. Biofeedback measures were done immediately before and after acupuncture treatment to assess for objective improvement. Setting: Veterans administration outpatient PM&R clinic; acupuncture has been utilized for pain control. In this case we have used SP 9, GB 34, GB 33, ST 36 in the opposite limb, amputee limb-GB 32, amputee distal stump points; side of amputation LI11, LI4 were also done. Results or Clinical Course: Patient demonstrated improvement after acupuncture. Improvement was seen in 1) HR variability recovery after stressor, 2) skin conductance, 3) pain scores, and 4) decrease and regularity in respiratory rate with abdominal breathing, and 5) EMG muscle tension in quadriceps muscle showed 40% decrease in muscle tension was noted. Overall improvement in scores since beginning of acupuncture treatment is 50%. Discussion: In this case, there were significant improvements in all 5 measures. This case report shows potential for acupuncture for treatment of chronic distal stump pain. Conclusions: Future studies with larger sample sizes are needed to find an objective tool to measure long-term effectiveness of acupuncture for amputee stump pain.

Sedation can be seen as a continuum from minimal drowsiness or plain anxiolysis to non-responsiveness and impaired ventilation, close to general anaesthesia. Therefore, the focus of the anaesthesiologist should be on ability of the patient to co-operate, to maintain his airway, and to breathe adequately. When planning the pharmaceutics and intensity of sedation, the practioner should take into account, not only the desires of the patient, but also the intraoperative safety issues, the course of recovery, and expected delay in street fitness after the procedure. In outpatient surgery, the intensity of sedation should naturally be shallower than in circumstances, where overnight stay is an option. Needless to say, sedation is not a solution, when regional anaesthesia appears to be incomplete or fully unsuccessful. Instead, surgical pain after regional anaesthesia should be treated with either repeated regional / local anaesthesia, or full-scale general anaesthesia, with adequate control of airway and breathing. The drugs most commonly used as intraoperative sedatives are: midazolam or other benzodiazepines, propofol, dexmedetomidine, and ketamine. The use of benzodiazepines is usually associated with strong amnesia, but the inter-individual variability is large. These drugs do not possess any analgesic effects, and combination with opioids may lead to hypoxia due to impaired ventilation. Propofol can be given as boluses, continuous infusion or using patient-controlled devices. Like benzodiazepines, propofol does not have any analgesic effects, and it can be combined with either ketamine of opioids. Propofol is a potent sedative, with a risk of rapid, unnecessarily deep sedation. Dexmedetomidine is a novel alpha2-adrenergic agonist, offering sedation, anxiolysis, hypnosis, analgesia, and sympatholysis, associated with patent airway and adequate breathing. Although pricy, it is considered as 'an ideal'sedative. Ketamine offers patent airway, analgesia and amnesia, but because of the risk of psychotrophic side effects it is only seldom given alone, but in combination with propofol or benzodiazepines. During light to 'moderate' sedation, verbal co-operation with the patient is the most reliable method to monitor the course of drug effect. However, the deepening sedation (i.e., the transition from 'moderate' to 'deep'sedation) should also be detected, or even predicted. Electroencephalogram (EEG) based indices, like BIS or Entropy, are alleged to display the depth of sedation / anaesthesia on numerical 100-0 scale. With these monitors, some obvious shortcomings appear. First of all, they are tuned to function optimally during general anaesthesia, i.e. out of the range of meaningful sedation. The EEG monitors assume GABAergic (hypnotic) drug effect; therefore they are useful with propofol and perhaps with benzodiazepines, but not ideal with dexmedetomidine, and useless with ketamine, nitrous oxide, or opioids. These indices, opposite to general belief, do not directly indicate the ''depth'' of anaesthesia, but the drug effect on EEG, instead. The drug effect of an opioid on EEG is similar to the effect of propofol ('slow EEG'), but the use of opioid does not guarantee unconsciousness (1). Therefore, the EEG monitors are not reliable with all drugs used to sedate a patient. Moreover, the most common source of EEG artifact during sedation, frontal muscle activity (EMG), is not easily filtered from the real EEG signal. Frontal EMG appears during arousal from anaesthesia, external stimulation, or nociception. It may change the reading of an EEG index without a change in the state of the patient. Also the EEG itself may change paradoxically during nociception, leaving the EEG indices meaningless (2). During adequate regional anaesthesia, a peripheral blockade of nociception is assumed. Therefore, the role of sedation is merely to comfort the anxious patient during surgery, and deep sedation is not needed. Even without nociception, frontal EMG is still commonly present during shallow sedation, and EEG indices are typically very high. As a rule of thumb, high EEG index is non-informative, while very low index value (below 40) indicates unnecessarily deep sedation. To conclude, the present EEG indices are not designed to monitor the sedative portion of an anaesthetic continuum scale. High-quality regional anaesthesia, associated with very light sedation and verbal communication, is currently the premium method to follow the state of the patient. EEG index can be used to avoid unnecessarily deep sedation, as long as GABAergic drugs are used.

This requires coordination between detrusor muscle contraction and urethral outlet complex relaxation. Disturbances in this coordination lead to voiding dysfunctions such as bladder outlet obstruction (BOO). BOO is characterized by increase in detrusor pressure with decreased urinary flow rate during voiding. Pressure flow study (PFS) is the current standard diagnostic test for BOO. It studies the relation between bladder contractility force and the urine flow output of this force. To perform a PFS, trans-urethral and rectal pressure sensitive catheters are mandatory to quantify detrusor pressure by subtracting the abdominal pressure from the intra-vesical pressure. The invasive nature of PFS can lead to potential morbidities such as urinary tract infections, discomfort and pain. Furthermore, it only measures the result of the detrusor contraction and not the function of the detrusor itself. Therefore, there is an apparent necessity for developing a non-invasive diagnostic technique to quantify detrusor muscle contractility. Such a non-invasive method could make diagnostic procedures more patient friendly. With radiofrequency (RF) ultrasound it is possible to estimate deformation in biological tissues [1]. This deformation can be either passive by applying an external compression, or active in case of contracting muscle. This technique has been applied in dynamic monitoring of local skeletal muscle strain during contraction [2]. In the current study we applied RF ultrasound to measure deformation of the detrusor muscle during the voiding phase. This may give a clue to the mechanisms of the generated force in relation to detrusor muscle structural and dynamic properties, under physiologic and under disease conditions. Study design, materials and methods The patient population consisted of 20 male patients suffering from LUTS/BPH (all subjects signed an informed consent). RF ultrasound data were acquired during the onset of voiding using a SONOS 7500 ultrasound system (Philips Medical Systems, Bothell, USA) equipped with a linear array transducer, 11-3L, fc = 7.5 MHz. The transducer was placed transversal above the pubic bone. In each patient ~20 seconds of data was acquired and stored for offline analysis. In all subjects, at the start of an increase in detrusor pressure the RF ultrasound data were acquired prospectively at a frame rate of 2 Hz (2 patients) and 5 Hz (18 patients) and stored for offline analysis. The urinary flow rate and intravesical pressure were recorded using standard urodynamic equipment (MMS Medical Measurement Systems, Enschede, The Netherlands). Displacement and strain in the detrusor muscle during voiding was estimated from the RF ultrasound data using a coarse-tofine strain estimation algorithm [3]. Strain estimation was corrected for detrusor movements during voiding using a tracking algorithm. On the first B-mode image of the acquired time-series a Region-Of-Interest (ROI) was drawn and the mean axial strain (i.e. strain in the direction of the ultrasound beam) in this ROI was calculated. Results In 8 patients RF ultrasound data was acquired during a part of the voiding cycle where there was an increase in detrusor pressure and urinary flow. In 5 out the 8 patients the axial strain showed a significantly positive correlation with the detrusor pressure (Spearman = 0.52 - 0.81, p<.05). Only one of these patients showed a negative correlation (Spearman = -0.61, p<.05) and two patients showed a weak non-significant correlation (Spearman = -0.18 (p = .07) and -0.20 (p = .08)). In 5 patients RF ultrasound data was acquired during an isovolumetric contraction (i.e. an increase in detrusor pressure without urinary flow). In all 5 patients the axial strain showed a significantly positive correlation with the detrusor pressure (Spearman = 0.70 - 0.99, p<.05). An example of strain in the detrusor during an isovolumetric contraction is shown in Figure 1. In 7 patients tracking of the bladder wall during voiding failed, either by out-of-plane motion of the bladder wall or erroneous acquisition. (Figure presented) Interpretation of results Strain in the bladder wall was significantly correlated with the detrusor pressure in 10 out of the 13 successfully acquired ultrasound data. The presented values of strain were cumulated with respect to the first acquired ultrasound image; an increase in axial strain therefore, indicates "thickening" of the detrusor muscle during voiding. Whereas a decrease indicates "thinning" of the detrusor muscle with respect to a previous muscle status. In all the patients with an isovolumetric contraction an increase in strain in the detrusor muscle was observed simultaneous with an increase in detrusor pressure. This measurement indicates that the thickening of the detrusor muscle is indeed caused by contraction of the muscle. Concluding message In a symptomatic patient population with LUTS we have shown that strain in the detrusor (estimated using radiofrequency ultrasound imaging) correlates positively with the detrusor pressure. This suggests that ultrasound strain imaging could possibly be used to detect detrusor muscle activity for the diagnosis and classification of LUTS.

The late-onset myopathic form consists of episodes of rhabdomyolysis, exercise intolerance, muscle cramps, and/or pain. Objectives: To report clinical variability of VLCAD deficiency, with presentation of two adult siblings with novel mutations in the ACADVL gene, one patient with muscle pain and exercise intolerance and the other remaining asymptomatic. Methods: Clinical assessment, needle electromyography, bloodspot and serum acylcarnitine profiling, fibroblast fatty acid flux studies, VLCAD enzymology, and molecular studies were performed on both subjects. Results: Patient 1 had a clinical history of exercise intolerance, delayed muscle weakness, and recurrent rhabdomyolysis. Acylcarnitine profiles indicated abnormal fatty acid oxidation. VLCAD enzyme activity was 12% of mean control value. Her sister, patient 2, is physically very active and asymptomatic. Serum acylcarnitine profile was mildly abnormal and VLCAD activity was 30% of control mean. Both sisters carry the novel mutations c.1748C>G (p.S583W) and the c.957G>A (p.S319S) in the ACADVL gene, one leading to an alteration in the amino acid sequence and the second likely affecting the stability of the messenger ribonucleic acid transcript, leading to a reduced amount of mature VLCAD protein. Conclusion: Primary disorders of fatty acid oxidation, including VLCAD deficiency, are treatable metabolic disorders. They should be considered in any investigation with a history of exercise-induced muscle pain, cramping, and rhabdomyolysis. The variable presentation of the two adult siblings carrying the same mutations suggests that other factors, likely both genetic and environmental, further modulate the observed phenotype.

Beside the mechanism of autonomic arousal reduction, we assessed if there is a change in the indirect measurement of the autonomic system and a modification ofpain-specific belief. Background: Biofeedback has been proven to be a valuable treatment for headache disorders. It seems to be effective by relaxing the patient, thus reducing autonomic arousal. In past studies, the variables measured were EMG, temperature and Blood Volume Pulse (BVP). We explored a new modality, the resonant frequency ofheart rate. Methods: 25 patients accepted to participate in a 5 session program spanning over 3 months. The first session marked the first day of the study and patients were seen at 1st, 2nd, 6th, and the final session at the 12th week. Preventive nor abortive treatments were not changed. During sessions 1 and 5, they were asked to fill MIDAS and the Survey of Pain Attitudes (SOPA) questionnaires they were taught abdominal respiration techniques with abdominal and thoracic bands and asked to slow their breathing rhythm down to 6 per minute until they reached their resonant frequency heart rate, measured by one derivation EKG. The biofeedback device used was Tought Technology "ProComp Infinity System". Patients were asked to practice this form of respiration at home for 20 minutes daily. The second session began by observing if they reached their resonant frequency without seeing the screen and followed by practicing with the screen. The third, fourth and fifth sessions were structured in the same manner. Heart rate variability was analysed and corrected with the "CardioPro Infiniti" software from Thought Technology Ltd (Trade mark). Results: Twelve patients completed the 5 session program. Results for MIDAS questionnaire for these 12 patients were: Mean MIDAS score before treatment was: 17.7 and at fifth session: 8.3. Mean days with headache (MIDAS question A) before treatment was: 52.9 days and at fifth session: 39 days. Mean headache intensity evaluation (MIDAS question B) before treatment was: 6/10 and at fifth session: 4.7/10. SOPA questionnaire didn't reveal clear differences between patients that complete the five sessions and those who stopped before the end of treatment. Differences between the first and last questionnaires for patients who finish the treatment show an increased score on control and emotion subscales and a lesser score on damage and handicap subscales. Heart rate variability data are still being analysed but there seems to be a tendency to higher parasympathetic over sympathetic balance, since a higher peak valley was seen in many patients at fifth session compared to the first one. Conclusions: Results suggest that HRV biofeedback should be considered as a preventive treatment for headache patients. It seems to be suitable for motivated patients since 50% of patients abandoned the program before completion. We think that the benefit derive from relaxation, internalisation of the locus of control and modification of sympathetic/parasympathetic balance.

Methods A totoal of 28 consecutive patients with Crowe type IV CDH received treatment using this surgical technique from June 2003 to June 2010. The follow-up was conducted at 3 days, 1, 6, and 12 months after the operation and later annually at the outpatient of our hospital. Sequential pelvic plain film and normotopia film of the affected hip joint were taken. The limp and the Trendelenburg sign were also assessed, the ischiadic nerve injury was also evaluated by electromyogram, and Harris hip scores were recorded. Results After operation, both the alignment and the position of the transverse osteotomies were good. None of the patients had presented complications of joint infection, prosthesis loosening, joint dislocation, or nerve injury. Conclusions S-ROM modular hip arthroplasty combined with transverse subtrochanteric shortening was a satisfactory and safe technique for the Crowe type IV congenital hip dislocation within a mean follow up of 53 months. Transverse subtrochanteric shortening could effectively prevent the distraction injury of sciatic nerve.

Changes in muscle activity and blood flow due to stress and unfavourable muscle loads are known underlying factors of work-related muscle pain. Aberration of the autonomic nervous system (ANS) is considered a possible mechanism. In the present study, participants (n = 23 Pain, n = 22 Control) performed autonomic tests which included a resting condition, static hand grip test (HGT) at 30% of maximal voluntary contraction, a cold pressor test (CPT) and a deep breathing test (DBT). HRV was analysed in time and frequency domains. MBF and muscle activity were recorded from the upper trapezius muscles using photoplethysmography and electromyography (EMG). The pain group showed reduced low frequency-HRV (LF) and SDNN during rest, as well as a blunted BP response and increased LF-HRV during HGT (DELTAsystolic 22 mm Hg; DELTALF(nu) 27%) compared with controls (DELTAsystolic 27; DELTALF(nu) 6%). Locally, the pain group had attenuated trapezius MBF in response to HGT (Pain 122% Control 140%) with elevated trapezius EMG following HGT and during CPT. In conclusion, only HGT showed differences between groups in systemic BP and HRV and alterations in local trapezius MBF and EMG in the pain group. Findings support the hypothesis of ANS involvement at systemic and local levels in chronic neck-shoulder pain. © Springer-Verlag 2011.

Upper extremity kinematics and electromyography (EMG) were obtained on a cycle-to-cycle basis for eight participants during two conditions, corresponding to "normal" and "high" work pace according to a predetermined time system for engineering. Indicators of fatigue, pain sensitivity and performance were recorded before, during and after the task. The level and variability of muscle activity did not differ according to work pace, and manifestations of muscle fatigue or changed pain sensitivity were not observed. In the high work pace, however, participants moved more efficiently, they showed more variability in wrist speed and acceleration, but they also made more errors. These results suggest that an increased work pace, within the range addressed here, will not have any substantial adverse effects on acute motor performance and fatigue in light, cyclic assembly work. STATEMENT OF RELEVANCE: In the manufacturing industry, work pace is a key issue in production system design and hence of interest to ergonomists as well as engineers. In this laboratory study, increasing the work pace did not show adverse effects in terms of biomechanical exposures and muscle fatigue, but it did lead to more errors. For the industrial engineer, this observation suggests that an increase in work pace might diminish production quality, even without any noticeable fatigue being experienced by the operators.

Confusion concerning the anatomy involved, the presenting symptomatology, the appropriateness and significance of various diagnostic tests, conservative and surgical management, and, finally, the variability of reported results of surgical intervention attests to the lack of consensus surrounding this condition. The terminology involved in various diagnoses for chronic heel pain is also a hodgepodge of poorly understood entities. © 2011.

A total of 20 men were selected to evaluate the effects of shoulder and back flexion angles on the upper-limb muscle activities, subjective discomforts and heart rates. Interesting findings were obtained from the coordination between back flexion angles and shoulder flexion angles. At a back flexion angle of 45degree, the discomfort and heart rates were the least at a shoulder flexion angle of 45degree. The %MVC also showed a similar trend. It could be inferred that the 0degree shoulder flexion angle would be a natural posture, when the back flexion angle is 0degree, whereas 45degree shoulder flexion might be a more natural posture when the back flexion angle is 45degree. STATEMENT OF RELEVANCE: This study evaluated the effects of back and shoulder flexion angles on subjective as well as objective measures. The findings of this study considered the coordination between two body flexion angles and could be used to improve the accuracy of existing ergonomics evaluation methods for body postures.

The purpose of this study was to apply linear and nonlinear methods to compare the structure of variability of midfoot kinematics and surface electromyographic (SEMG) signals between patients with medial tibial stress syndrome and healthy controls during gait.Fourteen patients diagnosed with medial tibial stress syndrome and 11 healthy controls were included from an orthopaedic clinic. SEMG from tibialis anterior and the soleus muscles as well as midfoot kinematics were recorded during 20 consecutive gait cycles. Permuted sample entropy and permutation entropy were used as a measure of complexity from SEMG signals and kinematics.SEMG signals in patients with medial tibial stress syndrome were characterized by higher structural complexity compared with healthy controls (p<0.001) while it was the opposite for the midfoot kinematics (p=0.01).Assessing the complexity of midfoot kinematics and SEMG activation pattern enabled a precise characterization of gait in patients with medial tibial stress syndrome. The reported inverse relationship in foot kinematics and SEMG complexity most likely point towards separated control processes governing gait variability. © 2011 Elsevier Ltd.

The aim of this study was to compare neck muscle endurance and fatigue characteristics during sub-maximal isometric endurance tests in patients with postural neck pain, with asymptomatic subjects. Thirteen female patients with postural neck pain and 12 asymptomatic female control subjects completed timed sub-maximal muscle endurance tests for the neck flexor and extensor muscles. Muscle fatigue, defined as the time-dependent decrease in median frequency electromyography (EMG), was examined using surface EMG analysis during the tests. The median extensor test holding time was lower but not significantly different in the neck pain group (165 s) that the control group (228 s) (p = 0.17). There was no difference between groups in the flexor test holding time (neck pain = 36 s, controls = 38 s) (p = 0.96). The neck pain group was characterised by greater variability in neck flexor (p = 0.03) and extensor (p = 0.006) muscle endurance. For both tests, the rate of decrease in median frequency EMG was highly variable within and between groups with no significant difference between groups for the flexor or extensor test (p = 0.05-0.82). Patients with postural neck pain did not have significant impairment of neck muscle endurance or accelerated fatigue compared to control subjects. However, the greater variability in these indices of muscle function may reflect patient-specific changes in muscle function associated with neck pain disorder. © 2010 Elsevier Ltd.

Ten healthy subjects and eleven LBP patients were asked to perform flexion-extension task, and the sEMG signals were recorded. Both the subject-level and the group-level PCfdr algorithms are applied to learn the sEMG coordination networks with the error-rate being controlled. The network features are further characterized in terms of network symmetry, global efficiency, clustering coefficient and graph modules. The results indicate that the networks representing the normal group are much closer to the order networks and clearly exhibit globally symmetric patterns between the left and right sEMG channels. While the coordination activities between sEMG channels for the patient group are more likely to cluster locally and the group network shows the loss of global symmetric patterns. As a complementary tool to the physical and anatomical analysis, the proposed network analysis approach allows the visualization of the muscle coordination activities and the extraction of more informative features from the sEMG data for low back pain studies. © 2011 Elsevier Ltd.

The focus of the current study was the design, development and testing of two simple ergonomic interventions to reduce exposure to these risk factors in small-scale commercial crab fishermen. In a laboratory study of these interventions, EMG and motion analysis systems were used to quantify changes in muscle force and body postures. The results of laboratory evaluation of the intervention designed to reduce the low back stress associated with hoisting the crab pots onboard showed significant reductions in muscle force requirements (erector spinae activity reduced by 25%) and peak sagittal trunk angle (reduced by 34%), while the results of the intervention designed to reduce shoulder stress during the process of shaking the crabs from the pots showed significant reductions in peak deltoid activity (reduced by 24%). A field test of these interventions provided a more subjective "usability" evaluation of the interventions. These responses were cautiously positive, providing insights into when these interventions would be most appropriate and under what conditions they would be more of a hindrance than a help. Relevance to industry: Engineering controls are recognized as the most effective methods of reducing exposure to risk factors for musculoskeletal injury. Engineering controls were developed for small-scale commercial crab fishermen and these interventions were tested in the laboratory and in the field. © 2011 Elsevier B.V.

Design, setting, participants, & measurements: Medical records of three patients from two French unrelated families with CLDN19 mutations were retrospectively examined. Results: Direct sequencing of CLDN19 identified a known variant (p.Gly20Asp) in all patients and a new missense mutation (p.Val44Met) in one (compound heterozygous). The patients' renal phenotype closely mimicked CLDN16-related nephropathy: low serum Mg2+ (<0.65 mmol/L) despite oral supplementation, hypercalciuria partly thiazide-sensitive, and progressive renal decline with ESRD reached at age 16 and 22 years in two individuals. Primary characteristics (failure to thrive, recurrent urinary tract infections, or abdominal pain), age at onset (0.8 to 16 years), and rate of renal decline were highly heterogeneous. Ocular involvement was identified in all patients, although two patients did not have visual loss. Additionally, exercise intolerance with pain, weakness, and electromyographical alterations mimicking a Ca2+/K+ channelopathy (pattern V) were observed in two of three individuals. These features persisted despite the normalization of serum K+ and Mg2+ after renal transplantation. Conclusions: Ocular manifestations, even subtle, and exercise intolerance mimicking mild to moderate periodic paralysis are two symptoms that need to be searched for in patients with FHHNC and may indicate CLDN19 mutations.

Method: Three-dimensional gait analysis and electromyography were performed on a group of 40 participants with clinically diagnosed mild to moderate medial knee OA. Associations between radiographic severity, defined using a visual analog radiographic score, and pain severity, defined with the pain subscale of the WOMAC osteoarthritis index, with knee joint kinematics and kinetics, electromyography patterns of periarticular knee muscles, BMI and gait speed were determined with correlation analyses. Multiple linear regression analyses of radiographic and pain severity were also explored. Results: Statistically significant correlations between radiographic severity and the overall magnitude of the knee adduction moment during stance (r2=21.4%, P=0.003) and the magnitude of the knee flexion angle during the gait cycle (r2=11.4%, P=0.03) were found. Significant correlations between pain and gait speed (r2=28.2%, P<0.0001), the activation patterns of the lateral gastrocnemius (r2=16.6%, P=0.009) and the medial hamstring (r2=10.3%, P=0.04) during gait were found. The combination of the magnitude of the knee adduction moment during stance and BMI explained a significant portion of the variability in radiographic severity (R2=27.1%, P<0.0001). No multivariate model explained pain severity better than gait speed alone. Conclusions: This study suggests that some knee joint biomechanical variables are associated with structural knee OA severity measured from radiographs in clinically diagnosed mild to moderate levels of disease, but that pain severity is only reflected in gait speed and neuromuscular activation patterns. A combination of the knee adduction moment and BMI better explained structural knee OA severity than any individual factor alone. © 2010 Osteoarthritis Research Society International.

Similar improvement in transfer ability or balance were seen with repetitive task training, biofeedback, and training with a moving platform. Walking speed was improved by physical fitness training, highintensity physiotherapy and repetitive task training. However, most of these trials were small and had design limitations. Material/Methods: In this article, randomized control trials (RCT's) published in 2009 of rehabilitation therapies for acute (<=2 weeks), sub-acute (2 to 12 weeks) and chronic (>=12 weeks) stroke was reviewed. A Medline search was performed to identify all RCT's in stroke rehabilitation in the year 2009. The search strategy that was used for PubMed is presented in the Appendix 1. The objective was to examine the effectiveness of these treatment modalities in stroke rehabilitation. Results: This generated 35 RCT's under 5 categories which were found and analyzed. The methodological quality was assessed by using the PEDro scale for external and internal validity. Conclusions: These trials were primarily efficacy studies. Most of these studies enrolled small numbers of patient which precluded their clinical applicability (limited external validity). However, the constraint induced movement therapy (CIT), regularly used in chronic stroke patients did not improve affected arm-hand function when used in acute stroke patients at <=4weeks. Intensive CIT did not lead to motor improvement in arm-hand function. Robotic arm treatment helped decrease motor impairment and improved function in chronic stroke patients only. Therapist provided exercise programs (when self-administered by patients during their off-therapy time in a rehabilitation setting) did improve arm-hand function. Tai Chi exercises helped improve balance and weight bearing. Exercise programs for community dwelling stroke patient helped maintain and even improve their functional state. © Med Sci Monit.

Our objective in the present study was to investigate whether dynamic modulation of axial postural tone can change through training. We examined whether teachers of the Alexander Technique (AT), who undergo " long-term" (3-year) training, have greater modulation of axial postural tone than matched control subjects. In addition, we performed a longitudinal study on the effect of " short-term" (10-week) AT training on the axial postural tone of individuals with low back pain (LBP), since short term AT training has previously been shown to reduce LBP. Axial postural tone was quantified by measuring the resistance of the neck, trunk and hips to small (+/-10degree), slow (1degree/s) torsional rotation during stance. Modulation of tone was determined by the torsional resistance to rotation (peak-to-peak, phase-advance, and variability of torque) and axial muscle activity (EMG). Peak-to-peak torque was lower (~50%), while phase-advance and cycle-to-cycle variability were enhanced for AT teachers compared to matched control subjects at all levels of the axis. In addition, LBP subjects decreased trunk and hip stiffness following short-term AT training compared to a control intervention. While changes in static levels of postural tone may have contributed to the reduced stiffness observed with the AT, our results suggest that dynamic modulation of postural tone can be enhanced through long-term training in the AT, which may constitute an important direction for therapeutic intervention. © 2010 Elsevier B.V.

On day one, subjects (N = 12) performed computer work with/without acute muscle pain induced in the trapezius muscle. Subsequently, eccentric exercise was performed to induce delayed onset muscle soreness (DOMS) in wrist extensor muscles. In presence of DOMS on day two, computer work recordings with/without pain were repeated. EMG signals were recorded from the descending part of trapezius bilaterally, flexor carpi ulnaris and extensor carpi radialis brevis. Experimental muscle pain in trapezius led to a decrease in the muscular activity of the wrist extensor (P < 0.02) and decreased the relative rest time in the wrist flexor even in presence of DOMS (P < 0.01). The present result suggests that shoulder pain plays a role in the coordination of wrist flexors and extensors during computer work. © 2010 Elsevier Ltd and The Ergonomics Society.

Relevance: Patellofemoral pain syndrome (PFPS) is a common condition in the sporting and general populations, particularly when repetitive lower limb loading is involved. Although the cause of PFPS is multifactorial, altered motor behavior of the vasti muscles contributes to chronicity of pain episodes. Mobilization of the patellofemoral joint is commonly implemented clinically for the management of patients with PFPS. The rationale underlying this approach is that mobilization of the patellofemoral joint may induce activation of afferent input upstream to spinal and supraspinal centers, but no studies support this. Participants: A total of 30 young healthy collegiate students were participated in this study, which involved individuals between 18 and 25 years of age (mean age 20.9+/-1.6 SD years). Methods: Three muscles were selected as target muscles including gluteus medius (GM), vastus lateralis (VL) and vastus medialis oblique (VMO) in each subject. EMG raw data were collected using Micro 1401 Data Acquisition system with Spike/Signal software (CED, UK) and analyzed using Matlab 7.0 (Mathworks, USA). Motor coordination of these muscles was evaluated through assessment of temporal parameters of EMG during functional tasks including heel rock, heel raise, step up, step down and single leg landing. The primary outcome measure was onset of VMO EMG relative to VL on the dominant side of the leg. This was identified visually as the time of increase in EMG activity from baseline. Fifteen repetitions of each task were performed in random order before and immediately following manual therapy intervention. Consistent with clinical practice, the manual therapy was received non-painful large amplitude passive mobilizations of the patellofemoral joint in a medial direction at a frequency of ~1.5 Hz. Analysis: Temporal measures of EMG were compared before and immediately after the intervention using paired t-test. All statistical analysis were used commercial statistical analysis program (SPSS 14.0, SPSS Inc, USA) with p value set at 0.05. Results: After the intervention of patellofemoral joint mobilization, the activations of VMO and VL were significantly altered in dynamic activities such as step down and drop landing (p < 0.0001). In addition, significant earlier activations of VMO in most activities were found after the intervention of joint mobilization (p < 0.0001). The significant changes in difference of activation time between VMO and VL were found in most dynamic activities (p < 0.01), except for heel rock. Interestingly, the significant delayed changes in GM activation were found in step up, step down and drop landing after the intervention of joint mobilization (p < 0.0001). Conclusions: Significant immediate altered motor coordination of these muscles was found in the healthy young people after patellofemoral joint mobilization, especially for VMO. Implications: These findings confirm the rationale that patellofemoral joint mobilization induces immediate alteration of vasti muscles in young healthy adolescents.

All participants must be computer users for at least 2 hours per day. Those with present or past history of neck and shoulder pain or injury in the past 12 month were excluded. Methods: Each participant performed typing task using a computer. The stroop-effect words (name of the color and color of the word) (SEW) were used for inducing the stress. There were five task conditions organized in increasing physical and/or mental demands: (1) self-paced copying, (2) fast copying, (3) fast copying SEW, (4) verbal SEW, and (5) prolonged SEW. Each task was performed for 5 minutes with 5 minutes rest except Task (5) with 20 minutes and Rest (5) at 10 minutes. Task (2) exerted the most physical stress whereas Task (5) induced the highest level of physical and mental stress. Surface electromyography (EMG) data were collected from bilateral cervical erector spinae and upper trapezii muscles throughout all 5 task and rest periods. Simultaneous heart rate variability (HRV) data was recorded using the Polar heart rate monitor. After each task, participants were asked to rate their perceived stress level. Analysis: EMG amplitudes were processed as root mean square (EMG-rms) and median (50th%) amplitudes were computed. HRV was expressed as the low frequency to high frequency ratio (LF/HF ratio). Repeated measures ANOVA was performed to compare differences among the 5 tasks and recovery periods for the outcome variables of EMG amplitudes, HRV and perceived stress. Results: The muscle activity amplitudes of bilateral UT and CES increased significantly in Tasks (2), (3), and (5). Changes in HRV correlated with task demands but not significantly differed among the tasks. For perceived stress, the participants showed significant increases in "tension" and "pressure", but not in "anxiety" and "unease". Muscle activities, HRV and perceived stress have recovered nearly to the baseline after all 5 rest periods. Conclusions: The results showed that both physical and mental workloads produced significant increases in cervical muscle activity and trends for increased heart rate variability. The participants also reported increased level of perceived tension and pressure. It is not known whether individuals with past history of musculoskeletal pain would respond differently during these similar task demands. This will be examined in the next phase of the study. Implications: The results provide better understanding of how individuals respond to the influence of physical and mental stress factors which should be addressed in physiotherapy management of musculoskeletal disorders.

Relevance: In evaluating pelvic floor muscles it is important to use reliable and accurate methods. Participants: Seventeen nulliparous women between 20 and 33 years of age (25.35+/-3.69), with a body mass index (BMI) between 19.84 and 24.88 kg/m2 (22.09+/-1.51), who participated in the procedure during three consecutive weeks. Methods: A dynamometer equipment was used to evaluate pelvic floor muscle strength. The deformation of the tongs of the device in the anteroposterior direction (sagittal plane) and left-right (frontal plane) were captured by two pairs of strain gauges, located in the region of movement between them, which delivered an electrical signal that, in turn, was captured by the signal conditioner module. The reliability was tested in three sessions, with a seven days interval between, excluding pre-menstrual and menstrual periods. Pelvic floor muscle contractions lasted 4 seconds, with an interval of 2 minutes, and were repeated three times on each evaluation day in order to obtain an average value. The volunteers were instructed not to perform exercises for the PFM at home during the three weeks of data collection. Equipment opening was standardized at 4.9N of passive force (force at rest) on the sagittal plane during a pilot study, ensuring the proper coupling to the vaginal canal walls and guaranteeing no discomfort or pain, considering the fact that the initial fitting of the instrument interferes directly with the contraction strength, that is, if a standard opening (in mm) is designated allowing for a better fitting for some volunteers, they will need to apply lower contraction than the volunteers to whom the fit was not quite satisfactory. The abdominal and gluteus muscles were monitored by surface electromyography, concomitantly to the assessment, aiming to isolate the pelvic floor muscle contractions. Analysis: To evaluate the test-retest reliability the intraclass correlation coefficient and the standard error of the measurement were used. Results: Intraclass correlation of pelvic floor muscle force values from good to excellent were found (0.78 for anteroposterior force and 0.48 for left-right force). The values of the standard error of the measurement for anteroposterior strength was 1.96N and 1.86N for left-right. Conclusions: Values of test-retest demonstrated that the equipment assessed to measure the anteroposterior and left-right force generated reliable pelvic floor muscle measurements. Implications: This equipment is a reliable method for assessing the pelvic floor muscle strength at the beginning and the end of treatment, to evaluate its effectiveness.

Relevance: Combined motions of trunk at varying exertion levels occur in most daily and occupational activities and are important risk factors of low back pain. Few studies have investigated trunk controllability and activation patterns of trunk muscles during multidirectional activities with different exertion levels. Participants: Twelve asymptomatic male subjects and 5 patients with chronic low back pain. Methods: Participants performed isometric contractions of trunk muscles in 8 angles and 3 levels of exertion. Subjects were asked to track the target line (path) and match the endpoint while maintaining torque for 3 seconds by exerting isometric contraction against B200 Isostation. The EMG activity of ten selected trunk muscles was collected in the three seconds end-point matching tasks. Analysis: Trunk controllability was determined by measuring constant error and variable error during tracking tasks. Trunk muscle activation patterns were examined using EMG tuning curves and measuring preferred direction (mean vector direction) and the index of spatial focus. Results: Constant error and variable error were significantly affected by angle (p < 0.001) and level (p < 0.001) of exertion during both phases of the tracking task. No significant difference in EMG tuning curves, preferred direction and the index of spatial focus was found for each muscle studied across exertion levels (P > 0.05). The index of spatial focus of most muscles studied was not changed with increasing moment magnitude. EMG variability of trunk muscles was significantly affected by angle and level of exertion and their interaction effect (p < 0.001). Descriptively, mean index of spatial focus was lower in patient with LBP than asymptomatic subjects in most muscles and three levels of exertion. Conclusions: Trunk controllability was significantly decreased during biaxial exertions. Higher exertion levels had a major negative impact on trunk controllability in both uniaxial and biaxial exertions. The index of spatial focus indicated that probably no shift to a higher co-contraction strategy has been adapted with increasing exertion magnitude in asymptomatic subjects. EMG variability of trunk muscles in asymmetric exertions may be associated with lower trunk controllability during combined exertions. Because of small sample size of patients group, no statistical analysis was performed to compare asymptomatic subjects and patient with LBP; however, the preliminary results showed that the mean index of spatial focus of external and internal oblique muscles was considerably lower in the patients with LBP compared to asymptomatic subjects, as shown with percentage difference. Implications: The results suggested that combined exertions and more strenuous efforts may impair trunk neuromuscular control, increasing the risk of low back pain. The preliminary findings showed altered neuromuscular control of trunk muscles in patients with LBP compared to asymptomatic subjects. Also, this preliminary result suggests that the index of spatial focus may have a potential ability to differentiate between asymptomatic subjects and patients with LBP.

Relevance: Symptoms associated with hypermobility are widespread and include musculoskeletal disorders, decreased balance and proprioception, and chronic pain. Stair climbing is an important functional task and can lead to pain or joint instability in hypermobile subjects. Especially in stair descent fast stabilization is important while the maximal vertical force of approximately 1.5 times body weight is reached in about 150 milliseconds in normal subjects. Participants: Fifty-four hypermobile (27.9+/-6.0 years 59.5+/-8.8 kg) and twenty-two normomobile women (26.4+/-6.2 years 59.6+/-5.7 kg) participated in this study. Groups were identified using the Beighton Score: the hypermobile (HM) had a score of 6/9 or more and the normomobile (NM) 0 or 1/9. Methods: Cross-sectional study. GRF were measured with two force plates embedded in a six step staircase. Muscle activation of six leg muscles was measured using surface EMG: tibialis anterior (TA), medial gastrocnaemius (GM), semitendinosus (ST), biceps femoris (BF), vastus medialis (VM) and vastus lateralis (VL). Analysis: The first maximum GRF peak (Fz1) was detected and normalized to body weight (%bw). Timing of the first peak (t1) and total contact time were further evaluated. EMG signal of six strides was normalized to maximum voluntary isometric contraction (%MVIC) and lowpass-filtered with a cutoff-frequency of 8.9 Hz. Peak and mean activation during stance and swing phase were calculated, as well as the activation level at heel strike (HS), toe off (TO) and at t1. Group comparisons were done using independent samples t-test with a significance level at p<=0.05. Results: For the GRF significant results were found in stair descent:HMhad lower Fz1 thanNM(144% bw vs. 156% bw, p = 0.023), longer t1 (153 milliseconds vs. 140 milliseconds, p = 0.007) and longer contact time (720 milliseconds vs. 665 milliseconds, p = 0.016). For the EMG only peak activation ofVMin ascent was significantly lower inHM(177% vs. 146%, p = 0.037). Activation levels at HS, TO and t1 showed significant difference for ST at toe off. In addition, several tendencies for different activity levels were found. Conclusions: The differences inGRFin stair descent indicate that the motion pattern inHMis altered, at least during weight acceptance. However, only little significant differences were seen in the EMG, maybe due to high inter-subject variability and thus high standard deviations in both groups. The longer time to reach a lower force peak may be a sign of less passive stability and an in-adequate muscle force with lower rate of force development. Further research should investigate whether similar differences could be found in other daily life movements or strength testing and what the reasons for the lower and later peak force could be. Implications: The differences in GRF on stair could be used as diagnostic tool in order to identify hypermobile subjects. Further, the differences found point toward altered and slowed movement control. Maybe a specific power training aiming the improvement of active joint stabilization could help hypermobile subjects to get a better movement control.

Relevance: There is widespread belief system that the bilateral activation of Transversus abdominis (TrAb) occurs before perturbations of the spine from any direction of the arm movement. This has been used to explain core stability programs and a cause of chronic low back pain. This presentation provides evidence for a need to re-interpret the role of the TrAb in core stability training. Participants: Normal pain free volunteers. Methods: A total of 10 participants had bilateral and surface and fine wire EMG (2 kHz) recordings taken during upper limb perturbations under different experimental conditions. 7 had full 3D inverse kinetic analysis of the trunk to determine magnitudes and direction of the trunk perturbations. Participants performed unilateral and bilateral upperlimb rapid movements to generate a range of rotation torques on the lumbopelvic region. Analysis of EMG signal amplitudes and onsets in the feed forward window were examined under different conditions. Analysis: Repeated measures ANOVA and multivariate analyses were undertaken to document the changes in EMG profiles (amplitudes in set epochs) under different kinetic perturbations. Principle components analysis was undertaken to examine the clusters of muscles under a wide range of kinetic loadings. Results: The data reveals that: unilateral Trab activation patterns are more closely related to patterns of the ipsilateral Internal Oblique and the contralateral biceps femoris than the opposite TrAb; the activation pattern of TrAb in the feed forward window relates to the direction and magnitude of the upper limb perturbation; there is little symmetry in the Left and Right TrAb activation patterns in the presence of rotation torques and finally when TrAb is activated symmetrically this occurs reatively later (i.e. delayed). Conclusions: These findings dismiss the common belief that normally TrAb acts symmetrically in a corset like action well before the onset of the deltoid (feed forward activation). During perturbations to the trunk, muscles respond according to their fibre orientation. Unilateral TrAb is part of a diagonal sling synergy that stiffens the trunk in response to (pending) rotation perturbations. Implications: A wide range of research theses and rationale for specific core exercises are based on the assumption that TrAb (Left and Right) has a unique action and pre-movement activation pattern, that acts bilaterally (like a corset) to protect the spine and this protection occurs independently of the direction of the perturbation. This is not what was observed in normal subjects. The behaviour of the muscles responding to rotation (Trab) can be altered by altered selection of motor patterns. In particular this can be explained by the push-throw continuum. Individuals with LBP may have altered selection strategies towards a pushing pattern than a throwing pattern and therefore brace to avoid rotation prior to moving. The selection of this bracing maneuver may nullify any need for the ipsilateral TrAb to pre-activate. This a priori behaviour explains delays observed in this population and also delayed onsets associated with anxiety and pain.

With increasing childhood obesity and more intense athletic activities at younger ages, degenerative disc disease may be under-recognized and more problematic than previously thought. Method: A single centre review of all patients presenting to tertiary care pediatric neurology, neuromuscular or orthopedic clinics identified as having degenerative disc disease by imaging of spine. Results: Ten patients were identified. The mean age at presentation was 14.3 years, Presenting symptoms included back pain n=6, weakness n=2, sensory disturbance n=1 and radicular headache n=1. Mean BMI was 24 with 3/10 patients having a BMI >30. The mechanism of disc disease was presumed to be chronic trauma n=4, acute trauma n=2, spondylolithesis n=1 and unknown n=3. MRI was performed in all patients with 3 patients also having EMG/NCS. The most common disc level involved was L4-L5 (n=3) with multiple levels in 2 patients. Management was surgical in 2 patients with the remainder receiving pain management, rest and physiotherapy. One patient had recurrent new radicular symptoms with a new disc herniation in the follow up period. Conclusion: This case series demonstrates the variability of mechanisms and clinical characteristics of disc disease in children. Larger case series will need to be completed to understand the role of potential risk factors for disc disease, such as obesity and athletic activity.

The purposes of this study were: (1) to examine the spinal kinematics of the cervical and upper thoracic regions and the associated electromyographic activities (EMG) in people with chronic mechanical neck pain (CMNP) during active neck movements and (2) to compare the movement coordination and EMG patterns with the healthy adults. Methods: 10 adults (8 females and 2 males) with CMNP and 10 age and gender matched control adults participated in this study. Spinal kinematics and EMG activities of 5 pairs of cervicothoracic muscles were assessed by the three dimensional electromagnetic motion tracking device and EMG system respectively while subjects performed self paced active neck movements in sitting. Coefficient of Cross Correlations (CCC) between spinal regions and EMG were compared between two groups with the analysis of variance (ANOVA). Results: The results demonstrated significant reduction in spinal movement and alteration in EMG coordination in CMNP group in performing free paced neck movement task, as revealed by the CCC (F1,18=4.754, p=0.04) for cervical and upper thoracic spinal kinematics and CCC (F1,18=5.083, p=0.04) for cervical kinematics and EMG activity. Conclusion: Aberrant coordination in the cervicothoracic spine and altered EMG activation pattern were found in people with chronic neck pain compared to healthy individuals. Cross correlation method provides a comprehensive analysis of coordination of movement across various spinal regions and the associated muscle activity in dynamic movement task.

This study used a typing task to investigate how externally induced stress modulated heart rate variability and muscle activation. The results would provide information on the possible physical and mental interactions in workrelated musculoskeletal disorders. Healthcare providers need to understand how individuals would respond to stressful task demands which are useful for designing intervention for patients with work-related musculoskeletal disorders. Methods Twenty three healthy adults were recruited by convenience sampling, with 11 males and 12 females (mean age=22.3+/-2.4 years; body mass index=20.4+/-12.7). All participants must be computer users for at least 4 h/day. Those with present or history of cardiac disease, hypertension, neck and shoulder pain or injury in the past 12 months were excluded. Ethical approval was received from the Human Research Ethics Committee of the Hong Kong Polytechnic University. Each participant performed typing task using a standardised computer workstation in a quiet and environmental control room with an adjustable chair and a stable desk. The stroop-effect words (name of the colour and colour of the word) (CWT) were used for inducing the stress. There were five task conditions organised in increasing physical and/or mental demands: (1) self-paced copying, (2) fast copying, (3) fast copying CWT, (4) verbal CWT and (5) prolonged CWT. Each task was performed for 5 min with 5 min rest except task (5) with 20 min and Rest (5) at 10 min. Task (2) exerted the most physical stress and task (3) showed higher mental and physical stress whereas task (5) induced the highest level of physical and mental stress. Heart rate variability (HRV) data was recorded using the Polar heart rate monitor Polar Electro, Finland). Simultaneous surface electromyography (EMG) data were collected from bilateral cervical erector spinae and upper trapezii muscles the Noraxon Telemyo 2400T G2 System (Noraxon, USA Inc. USA) during all five task and rest periods. After each task and rest, participants were asked to rate their perceived stress level. The R-R interval values (ms) were computed from raw signal curves in the software and exported as text files for further processing. R-R intervals and spectrum analysis of HRV was performed in fast fourier transformation (FFT) using the a HRV Analysis software version 11.1.0 (Nevrokard, Slovenia). Low frequency (LF 0.04-0.15 Hz), high frequency (HF 0.15-0.40 Hz), LF/HF ratio and total power (normalised units, nu) were processed for data analysis. HRV was expressed as the low frequency to high frequency ratio (LF/HF ratio). EMG amplitudes were processed as root mean square (EMG-rms) and median (50th%) amplitudes were computed. Results Repeated measures ANOVA was performed to compare differences among the five tasks and recovery periods for the outcome variables of HRV, EMG amplitudes, and perceived stress. Paired t-test was conducted to compare the change among five tasks. Changes in HRV for LF, HF, LF/HF ratio and total power correlated with task demands with significantly differed among the tasks (p<0.05). Task (3) and task (5) were elicited higher response on LF/HF ratio. The muscle activity amplitudes of bilateral UT and CES increased significantly in tasks (2), (3) and (5). For perceived stress, the participants showed significant increases in 'tension' and 'pressure', but not in 'anxiety' and 'unease'. HRV, muscle activities and perceived stress have recovered nearly to the baseline after all five rest periods. Conclusion The results showed that both physical and mental workloads produced significant increases in heart rate variability and cervical muscle activity. The participants also reported increased level of perceived tension and pressure. It is not known whether individuals with past history of musculoskeletal pain would respond differently during these similar task demands. This will be investigated in the future study. The results provide better understanding of how individuals respond to the influence of physical and mental stress factors which should be addressed in physiotherapy management of cardiovascular responses and musculoskeletal disorders during higher physical and/or mental workload.

This initiates depolarization of the axons that the patient describes as electric shocks in the dermatomes innervated. We call these paresthesias. In this article we describe the origin and consequences of paresthesias and we discuss changes in the technique that might reduce the incidence. Introduction: The contact of a needle tip with a nerve is enough stimuli to trigger a response, a mechanical paresthesia (1-2). It is nor clear if the trauma only leads to a sensory excitation or if it is able to induce also a motor response. Neither is it known which axons are activated to spread the stimulus that the patient describes as paresthesia. One author pointed at the nervi nervorum, but this hypothesis has little support, since the nervi nervorum are unmyelinated afferent fibers with a slow conducting speed and we expect a fast transmission in a mechanical paresthesia (3). The paresthesia begins with a mechanical stimulus along the axon. The disruption of the axon's membrane can cause an excitatory stimulus due to the ionic changes produced by the altered barrier that maintains the concentrations on both sides of the plasmolema (3). However, this mechanism was poorly considered by Hogan (3). He thinks that paresthesias can be initiated without any damage. It is possible by contacting a motor nerve root without being aware of the trauma. In this case, the patient would not notice a paresthesia or even a motor response, due to the fact that an insufficient number of muscle fibers were activated to induce a muscle movement (3). The electrophysiological mechanisms involved in a paresthesia caused by a needle trauma have been little studied. With electromyography, action potentials can be registered and analyzed in nerves stimulated with a needle tip: bursts of action potentials of different intensity and duration, depending on the degree of lesion. On the other hand, the chronic paresthesia that persists after nerve damage has been described extensively. A paresthesia is a response to an abnormal pattern of activity with ectopic impulses generated from asynchronous discharges of high frequency bursts in different sensorial units, resulting in an abnormal perception (4). The source of this ectopic activity is located at the centre of the fibers, where in normal physiological conditions action potentials are nor generated (5). In normal conditions, the nodal region is responsible for the transmission of the action potentials, whereas the internodal region determines the membrane action potential. The mechanisms responsible for the action potentials (6-7) can be resumed in two: 1. Activation of persistent Na+ channels. These channels are activated by membrane potentials more hyperpolarized than those of inactivated Na+ channels (by approximately 15 mV). They remain active or with slow inactivation, enough to result in Na+ currents to cause an unstable membrane and to initiate repeated action potentials. 2. Activation of regenerative K+ currents. These currents occur at internodal regions, as response to a state of hyperpolarisation and tend to stabilize the membrane (8-9). The abnormal activation of these currents in a normal nerve could be responsible for chronic paresthesias caused by a previous trauma or lesion followed by an ischemic phenomenon (10-11). This results in bursts of high frequency action potentials in regions where previously was impossible to occur. Paresthesias in subarachnoid anesthesia: We obtain paresthesias frequently when we do a lumbar puncture either with diagnostic, therapeutic or anesthetic purposes. The incidence varies between 4,5 and 18% according to different factors (12-13), although this is difficult to asses because most of the times is not reflected in the clinical history. For the same reason, it is difficult to know the consequences of these paresthesias, because patients do not have usually a follow up after discharge. Systematic electrophysiological studies in these patients after discharge would help to asses the consequences, and although in some cases are performed, it is not standard procedure, since it is not indicated. Another approach to this problem is by reviewing cases of patients who had a lumbar puncture and present paresthesias and neurological deficits, in a Hospital and during a determined period. This number varies between 0.3 and 1.7 / 1.000 according to two studies (14-15). However, considering that complications are infrequently published, this number is lower that the real incidence. Looking at retrospective studies, particularly in cases of multicenter studies with a large number of anesthesiologists involved, paresthesias are usually underestimated and despite the high incidence, they are not considered potentially harmful and therefore are nor included in the clinical history. Phillips (16) in 1969 found paresthesias in 93 cases of a total of 10,440 spinal anesthesias (0.9%). Horlocker (15) in 1997 described the occurrence of paresthesias in 298 patients from 4,767 of spinal anesthesia (6.3%) with 4 patients who presented persistent paresthesias. Horlocker postulated for the first time in 1997 the statistical association between paresthesia and neurological deficit. Auroy (17) also in 1997 and after review of 40,640 cases who had spinal anesthesia, found 19 radiculopathies, 12 of which had paresthesia during the lumbar puncture and 2 cases experienced pain during the injection of local anesthetic. Neurological deficits after subarachnoid anesthesia occur not only from direct trauma to de nerves but also from intraneural administration of the local anesthetic (18-19). Other factors that may contribute are spinal cord ischemia, injection of wrong medication with neurotoxic effects or formation of hematomas in the cauda equina. Origin of paresthesias: The majority of paresthesias are caused by puncture to the nerves of the cauda equina, rather than by inadverted injection within the conus medullaris (18). A lumbar puncture should be done below the level of the conus medullaris (20). The problem to consider is the variability in the lower limit of the conus within the spinal canal. On the other hand, the line between both iliac crests, also called Tuffier's line, does not correspond to a fixed point at lumbar level (21-22). When this line is used to do an epidural or spinal puncture, there could be an error up to one vertebral level that added to the individual variability of the position of the conus medullaris, it is possible to do an inadvertent puncture to the conus medullaris, if the chosen level was L2-L3. If the paresthesia is due to a trauma, the consequence varies depending on the size of needle, type of tip of needle and how deep enters within the nerve root. Probably the damage is greater when the roots are tense or when the needle is introduced careless, but since we can not see the structures inside the spinal canal, it is nor possible to determine how big are the nerves that we touch. With 25 G needles or even smaller sizes the nerve penetration is possible (23). However this possibility is not easy to occur "in vivo", unless there is some tension on the nerves due to the hyperflexion of vertebrae or in the case of a nerve root puncture next to the foraminal orifice, where there is little space to displace the nerve. This latter option is possible when the needle is directed laterally in the dural sac and advanced to the antero-lateral space where the nerve roots are located. It is difficult to pierce a nerve root "in vivo". These tend to move aside when the needle is advanced slowly and carefully. Morphology and distribution of nerve roots: At the cauda equine level the diameter of nerve roots varies between 0.5 and 2.3 mm. (Figure Presented) Posterior roots are bigger than anterior roots (23). The size of anterior roots increase from 1.1 to 1.8 mm at lumbar level, and decrease from 1.9 to 0.5 mm in the sacral region. Posterior nerve roots at lumbar level have a diameter of 1.3 to 2.1 mm and in the sacral region 2.3 to 1 mm. It is al L5-S1 where the nerves reach the biggest size (23). Axons are organized in bundles that remind the fascicles of peripheral nerves, although they are not fascicles, but grouped axon not separated by perineural cells (23). The total amount of myelinic axons within the nerve root may vary between 4,500 and 7,900 axons. (Figure Presented) Another aspect to consider is the distribution of the nerve roots within the dural sac (24-26). It is interesting to see that they are located less frequently in the posterior area. This anatomic conclusion could be of great help when performing a lumbar puncture, since we may advance the needle few millimeters, without a great risk of causing paresthesias. We should know that the position of nerve roots at different vertebral levels is not at random, but rather follows a pattern (18-19, 27). This depends on the location of the intervetebral foramina and the distance among them. Motor and sensorial nerve roots, are independent structures with a macroscopic origin at the nerve rootles, from 7 to 8, coming out the posterior-lateral region of the spinal cord in case of sensorial roots and from 4 to 6 located anterior-lateral in case of the anterior roots. When they leave the spinal cord or the conus medullaris they run together, although independently until reaching the internal orifice of the dural sac, located anterior-laterally. The motor and sensorial roots are centrally located distal to the conus medullaris. When we analyze histological sections of the dural sac at different levels, from the second lumbar level down, a nerve root runs progressively more laterally within the dural sac (24-26).

This study aimed to identify the neural determinants of impaired control of an accurate task with nociceptive stimulation. Methods: Muscle pain was induced by infusion of hypertonic saline into the abductor digiti minimi muscle of 11 men. Intramuscular EMG signals were recorded from the same muscle during four isometric contractions of 60-s duration at 10% of the maximal force (MVC), performed before (baseline), after the injection of hypertonic (pain) or isotonic saline (control), and 15 min after pain was no longer reported. Each contraction was preceded by three 3-s ramp contractions from 0% to 10% MVC. The low-frequency oscillations of motor unit spike trains were analyzed by the first principal component of the low-pass filtered spike trains (first common component, FCC), which represents the effective neural drive to the muscle. Results: Pain decreased the accuracy of task performance (coefficient of variation, CoV, for force: baseline, 2.8+/-1.8%, pain, 3.9+/-1.8%, P < 0.05) and reduced motor unit discharge rates (11.6+/-2.3 pulses per second, pps, vs. 10.7+/-1.7 pps, P < 0.05). The motor unit recruitment thresholds, inter-spike interval variability, strength of motor unit short-term synchronization, and strength of common drive did not change across conditions. However, the FCC signal was correlated with force (R = 0.45+/-0.06) and the CoV for FCC increased with pain (5.69+/-1.29% vs. 7.83+/-2.61%, P < 0.05). Conclusions: These results indicate that nociceptive stimulation increased the low-frequency variability in synaptic input to motor neurons.

Saunders Ltd MH - *pain MH - *muscle MH - *Europe MH - arm MH - electromyogram MH - injection MH - human MH - male MH - limb pain MH - sodium chloride AB - Background and Aims: Reaching movements may be simplified by combining few muscle synergies [1]. We investigated the role of nociceptive afferent input on modular control of the upper limb during reaching tasks. Methods: Surface electromyographic (EMG) signals were recorded from 12 muscles of the upper limb of 6 men during multijoint planar reaching tasks in 12 directions in two conditions: at baseline (2 repetitions) and following the injection of hypertonic saline either in the anterior deltoid (n = 3) or the triceps (n = 3) muscle. Muscle synergies were extracted with nonnegative matrix factorization of the EMG envelopes. Similarity between different synergy sets were assessed by the cosine of the principal angles between subspaces spanned by them [2] and the coefficient of determination r2 between estimated and recorded muscular activation patterns. Results: For both the baseline and the pain condition, the data sets could be described by a low dimensionality which was the same for both sets. Three synergies were sufficient to describe the EMG patterns in both conditions [r2 = 84.9+/-5.3 (baseline), r2 = 82.5+/-4.4 (pain)]. The cosine of first three principal angles was >=0.9 for the subspaces spanned by the synergy sets in both baseline conditions and was >=0.8 for the synergy sets across the baseline and pain condition. Conclusions: Reaching movements remain organized in a modular fashion in the presence of experimentally induced upper limb pain.

Objectives: To investigate the TCRs receptive fields organization in humans. Methods: TCRs were recorded from the neck muscles after stimulating the skin of the face on 9 different sites. Three median (glabella, supra- and infra-lip) and six lateral (supra- and infra-orbital and lip angles) sites were stimulated according to the distribution of the three branches of the trigeminal nerve. Trapezium, sternocleidomastoideus and semispinalis capitis muscles were bilaterally recorded from 20 subjects. Sensory and pain thresholds (ST, PT) were recorded. The reflex onset and magnitude (root mean square) were measured at 2xPT. The subject pain perception was measured by a 0-10 score VAS scale. The kinematic responses of both neck and head (flexion-extension, lateral flexion, torsion) were recorded by means of electrogoniometers. Results: ANOVA for repeated measures revealed no differences in the ST and VAS score values between sites, whereas lower PT values were found after stimulation of the ophthalmic region sites (p < 0.05). A significant effect of the stimulation sites on the TCRs magnitude was found (p < 0.01). In particular it was revealed: (i) a TCRs magnitude gradient according to the innervation territory of the trigeminal nerve branches (ophthalmic>maxillary>mandibular); (ii) a close relationship between the stimulation site and the EMG and kinematic responses in each muscle according to its role in the withdrawal strategy. Conclusions: A detailed TCRs organization, in which each neck muscle has its own reflex receptive field, may explain the head and neck withdrawal strategies in humans. Although the nocifensive function of the TCRs, our study suggests that the CNS exploits the TCRs modules to select muscle synergies governing the head and neck postures and movements.

Nine untrained women were familiarized with 7 functional coordination exercises 12 times during 4 weeks before testing. Surface electromyographic (EMG) activity was obtained from rectus abdominus, erector spinae, obliquus externus, and trapezius during the exercises with 2-4 levels of progression. Electromyography was normalized to the maximal EMG activity during maximal voluntary contractions, and a p value <=0.05 was considered significant. All recorded muscles reached sufficiently high levels of activity during the coordination exercises for strength gain (>60% of maximal EMG activity). Type of exercise played a significant role for the attained muscle activity. Body position during the exercises was important for the activity of the erector spinae, and level of progression was important for the activity of the trapezius. The findings indicate that depending on type, body position, and level of progression, functional coordination training can be performed with a muscle activity sufficient for strength gain. Functional coordination training may therefore be a good choice for prevention or rehabilitation of musculoskeletal pain or injury in the neck, shoulder, or trunk muscles. © 2010 National Strength and Conditioning Association.

OBJECTIVE: To determine whether abnormal motor activity plays a role in deep paraspinal tissues that appear abnormal to palpation. METHODS: Using an observational study design, the PVG of participants with thoracic pain were palpated by two examiners for consensus on the most marked level of tissue abnormality. Dual fine-wire, intramuscular electrodes were inserted into the deep transversospinalis (multifidus, rotatores) muscles at the abnormal level and at two normal sites (above and below the abnormal level). Surface electrodes were placed over the erector spinae muscles adjacent to each intramuscular electrode site. Electromyography signals were recorded during initial prone resting, three maximal voluntary isometric contractions (MVIC), and a second prone resting. The area under the curve for a 2-second period was analyzed for each condition, and values were normalized and reported as a percentage of MVIC. Data were analyzed using a 2-factor repeated-measures analysis of variance. RESULTS: Twenty-five participants with mean (SD) thoracic pain of 3.3 (1.9) on a 0 to 10 visual analog pain scale completed the study protocol. There were no statistically significant differences in normalized resting activity between the three intramuscular sites (P=.25) or between the three surface sites (P=.33). Substantial variability in normalized resting activity at each of the three intramuscular sites was evident (mean [SD] percent of MVIC: abnormal 7.83 [8.76]; normal 9.47 [8.45], 6.65 [7.39]). No statistically significant differences existed in the intramuscular EMG values between the two resting baseline periods (P=.10). CONCLUSION: The lack of statistically significant differences between EMG activity at the abnormal and normal paraspinal sites suggests that factors other than muscle activity are responsible for the apparent abnormality of these tissues to palpation. Investigation of these regions for increased tissue fluid and inflammatory mediators is recommended.

Thirteen healthy male subjects performed computer work with superimposed feedback either eliciting passive (rest) or active (approximately 30% MVC) pauses based on fuzzy logic design and a control session with no feedback. HD-EMG signals of upper trapezius were recorded using a 5 x 13 multichannel electrode grid. From the HD-EMG recordings, two-dimensional maps of root mean square (RMS), relative rest time (RRT) and permuted sample entropy (PeSaEn) were obtained. The centre of gravity (CoG) and entropy of maps were used to quantify changes in the spatial distribution of muscle activity. PeSaEn as a measure of temporal heterogeneity for each channel, decreased over the whole map in response to active pause (P < 0.05) underlining a more homogenous activation pattern. Concomitantly, the CoG of RRT maps moved in caudal direction and the entropy of RMS maps as a measure of spatial heterogeneity over the whole recording grid, increased in response to active pause session compared with control session (no feedback) (P < 0.05). Active pause compared with control resulted in more heterogeneous coordination of trapezius compared with no feedback implying a more uneven spatial distribution of the biomechanical load. The study introduced new aspects in relation to the potential benefit of superimposed muscle contraction in relation to the spatial organization of muscle activity during computer work. © 2010 Springer-Verlag.

This study used mixed modeling to identify observed and self-reported predictors of mean, 90th percentile, and cumulative low back muscle activity to help researchers efficiently assess physical exposures in epidemiological studies. Full-shift low back electromyography (EMG) was measured for 133 worker-days in heavy industry. Additionally, full-shift, 1-min interval work-sampling observations and post-shift interviews assessed exposure to work tasks, trunk postures, and manual materials handling. Data were also collected on demographic and job variables. Regression models using observed variables predicted 31-47% of the variability in the EMG activity measures, while self-reported variables predicted 21-36%. Observation-based models performed better than self-report-based models and may provide an alternative to direct measurement of back injury risk factors.

The focus was a supine bilateral leg-loading task that incorporated a slide (level 4) or no slide (level 5). Thirty-three healthy subjects (mean age 24 years) completed the task while surface electromyograms (EMG) from 5 abdominal muscle sites were recorded. Subjects were assigned to stable or unstable groups based on their ability to minimize lumbar-pelvic motion. After time and amplitude normalization, electromyography waveforms were entered into a pattern recognition procedure and scores for each principal pattern were calculated. Four principal patterns explained 90% of variance in the waveform data, with these principal patterns capturing the mean pattern, the relative amplitude change during the leg-extension phase, and subtle changes in shape throughout the exercise. Significant interactions (p < 0.05) were found for principal patterns; 1, 2, and 4 scores; and significant main (p < 0.05) effects for principal pattern 3 scores. These results illustrate temporal synchrony among the abdominal wall muscle activation during the bilateral leg-loading tasks; however, there was less variability in the activation patterns during the leg-lift and leg extension-phases for those who were able to minimize lumbar-pelvic motion compared to those who were unable to perform the task correctly. These results illustrate the need to focus on coordinated recruiting of the abdominal wall muscles in an organized manner and not simply increasing the intensity of activation for stabilization training.

This study aimed to investigate masticatory muscle group activity and heart rate variability change when the tongue was placed on the palate or the floor of the mouth in a healthy pain-free sample. Study design: Participants were 23 females and 18 males with a mean age of 19.6 years (standard deviation = 1.5). Muscle activity was measured using surface electromyography and heart period were measured using electrocardiography. The experimental protocol consisted of 3 periods: baseline, tongue placement on the floor of mouth, and tongue placement on palate. Results: Results indicated significantly more activity in the temporalis and suprahyoid muscle regions as well as a significant reduction in heart rate variability when the tongue was positioned on the palate compared with tongue position on the floor of the mouth. Conclusions: Instructions to place the tongue on the roof of the mouth are not instructions that will promote reduced physiological functioning (i.e., relaxation) but rather promote small, but potentially important increases in overall activity as indexed by muscle tone and cardiac function. © 2009 Mosby, Inc.

Recently, there has been increased focus on defining biological aspects of neck pain. Studies have indicated that neurophysiological, biomechanical, and motor control abnormalities are present and may be useful either in prognosis or classification. We review some of these findings in the context of our own work defining biological markers that may form the basis for clinical tests that can be used for prognosis, classification, or outcome evaluation in patients with neck pain. We have identified abnormalities in neurophysiology using quantitative sensory testing (vibration, touch, and current perception) and response to cold provocation that are related to neck disability. We have identified altered muscle biochemistry by measuring circulating muscle proteins in a lumbar surgery model and are now applying those methods to whiplash injury. We have incorporated capnography into treatment to address central physiological changes present in some patients by monitoring and training CO2 levels. We have developed an innovative new test, the Neck Walk Index, that captures abnormal control of head movement during slow gait as a means of differentiating patients with neck pain from either unaffected controls or individuals with other pathologies. We have used time-varying 3-dimensional joint orientation kinematics to assess deficits in motor control during an upper extremity reach task, the results showing that poor coordination and control of the shoulder girdle leads to shoulder guarding and inconsistencies in elbow joint movement. Despite some promising early results, future research is needed to determine how these measures help clinicians to diagnose, evaluate, and forecast future outcome for patients who present with neck pain.

OBJECTIVES: To provide background theory and information and to describe relevant applications of autocorrelation and cross-correlation methodology as they apply to the field of motor control in human movement and rehabilitation research. BACKGROUND: Commonly used methodologies for pattern and event recognition, determination of muscle activation timing for investigation of movement coordination, and motor control are generally difficult to implement, particularly with large datasets. A brief description of the underlying mathematical theory of correlation analyses is given, followed by 4 different examples of how this methodology is useful for research in the movement sciences. METHODS: Examples demonstrating the utility of correlation analyses are presented from several different studies conducted at the University of Waterloo. RESULTS: Autocorrelation was used to demonstrate the presence of 60-Hz noise in an electromyography signal that was not visible in the raw data. A "top-down" paraspinal muscle activation pattern was demonstrated for healthy adults during gait, with the use of cross-correlation. Cross-correlation was also used to quantify coactivation of bilateral gluteus medius muscles during standing in individuals who developed low-back pain. Gender differences in gluteus medius control of mediolateral center of pressure were seen with the use of cross-correlation. CONCLUSION: Autocorrelation and crosscorrelation have been shown to be an effective tool for several different applications in the movement sciences. Examples of the method's utility include noise detection within a signal, determination of relative muscle activation onsets for postural control, objective quantification of muscle coactivation, and relating muscle activations with mechanical events.

Nine untrained women were familiarized with 7 functional coordination exercises 12 times during 4 weeks before testing. Surface electromyographic (EMG) activity was obtained from rectus abdominus, erector spinae, obliquus externus, and trapezius during the exercises with 2-4 levels of progression. Electromyography was normalized to the maximal EMG activity during maximal voluntary contractions, and a p value < 0.05 was considered significant. All recorded muscles reached sufficiently high levels of activity during the coordination exercises for strength gain (>60% of maximal EMG activity). Type of exercise played a significant role for the attained muscle activity. Body position during the exercises was important for the activity of the erector spinae, and level of progression was important for the activity of the trapezius. The findings indicate that depending on type, body position, and level of progression, functional coordination training can be performed with a muscle activity sufficient for strength gain. Functional coordination training may therefore be a good choice for prevention or rehabilitation of musculoskeletal pain or injury in the neck, shoulder, or trunk muscles.

Maximal isometric voluntary contractions, postural sway measures of each leg, and muscular activities of the ankle muscles were recorded before and immediately after the fatiguing exercise.As expected, the latter induced a decrease in maximal voluntary peak force associated with a greater variability of the relative contribution of each leg on the CoPres, enhanced all postural parameters of the non-exercised leg. A significant decreased of the tibialis anterior EMG activity for the Ex leg and an increased one for the NoEx leg. Finally, following unilateral fatigue, the body sway destabilisation seemed to occur only along the medio-lateral (ML) axis.The enhanced and greater variability of the variance along ML axis might be explained by the recourse at the loading-unloading strategy choice and suggests a central attempt to compensate for pain sensation. © 2009 Elsevier Ltd.

Much like physical therapy, biofeedback training requires active participation on the part of patients and often regular practice between training sessions. Clinical biofeedback may be used to manage disease symptoms as well as to improve overall health and wellness through stress management training. Research has shown that biofeedback interventions are efficacious in treating a variety of medical conditions, and many Americans are turning to biofeedback and other less traditional therapies for their routine healthcare. Clinical biofeedback training is growing increasingly popular in the USA, as many people are seeking out relatively new approaches to healthcare. This article provides an overview of clinical biofeedback training, outlines two models of training, details research which has established how effective biofeedback is in patients with a given disease, and describes who should be referred for biofeedback training. © 2010 Radcliffe Publishing.

The root mean square (RMS) value was calculated for each channel, and then a 160x120 matrix was constructed using a linear cubic spline interpolation of each scan to create a 2-D color topographic image. Along a definite interval of action, a series of RMS topography matrices was concatenated as a function of position and time, to form a dynamic topographical video of lumbar muscle activity. Relative area (RA), relative width (RW), relative height (RH) and Width-to-Height Ratio (W/H) were chosen as the four quantitative parameters in measuring topographic features. Normal RMS dynamic topography was found to have a consistent, symmetric pattern with a high intensity area in the paraspinal area. LBP patients had a different RMS dynamic topography, with an asymmetric, broad, or disorganized distribution. Quantitative SEMG features were found significantly different between normal control and LBP. After physiotherapy rehabilitation, the dynamic topography images of LBP tended towards the normal pattern. There are obvious differences in lumbar muscle coordination between healthy subjects and LBP patients. The dynamic topography allows the continuous visualization of the distribution of surface EMG signals and the coordination of muscular contractions. © 2009 Elsevier Ltd. All rights reserved.

The repair is based on a movement-based re-learning theory which requires at least three levels of description: the movement or pattern (and anamnesis) level, the collective variable level, and the neuron level. Upon CDT not only the actually performed movement pattern itself is repaired, but the entire dynamics of CNS organization is improved, which is the theoretical basis for (re-) learning transfer. The transfer of learning for repair from jumping on springboard and exercising on a special CDT and recording device to urinary bladder functions is investigated at the neuron level. At the movement or pattern level, the improvement of central nervous system (CNS) functioning in human patients can be seen (or partly measured) by the improvement of the performance of the pattern. At the collective variable level, coordination tendencies can be measured by the so-called 'coordination dynamics' before, during and after treatment. At the neuron level, re-learning can additionally be assessed by surface electromyography (sEMG) as alterations of single motor unit firings and motor programs. But to express the ongoing interaction between the numerous neural, muscular, and metabolic elements involved in perception and action, it is relevant to inquire how the individual afferent and efferent neurons adjust their phase and frequency coordination to other neurons to satisfy learning task requirements. With the single-nerve fibre action potential recording method it was possible to measure that distributed single neurons communicate by phase and frequency coordination. It is shown that this timed firing of neurons is getting impaired upon injury and has to be improved by learning. The stability of phase and frequency coordination among afferent and efferent neuron firings can be related to pattern stability. The stability of phase and frequency coordination at the neuron level can therefore be assessed integratively at the (non-invasive) collective variable level by the arrhythmicity of turning (coordination dynamics) when a patient is exercising on a special CDT device. Upon jumping on springboard and exercising on the special CDT device, the intertwined neuronal networks, subserving movements (somatic) and urinary bladder functions (autonomic and somatic) in the sacral spinal cord, are synchronously activated and entrained to give rise to learning transfer from movements to bladder functions. Jumping on springboard and other movements primarily repair the pattern dynamics, whereas the exactly coordinated performed movements, performed on the special CDT device for turning, primarily improve the preciseness of the timed firing of neurons. The synchronous learning of perceptuomotor and perceptuobladder functioning from a dynamical perspective (giving rise to learning transfer) can be understood at the neuron level. Especially the activated phase and frequency coordination upon natural stimulation under physiologic and pathophysiologic conditions among alpha and gamma-motoneurons, muscle spindle afferents, touch and pain afferents, and urinary bladder stretch and tension receptor afferents in the human sacral spinal cord make understandable that somatic and parasympathetic functions are integrated in their functioning and give rise to learning transfer from movements to bladder functions. The power of this human treatment research project lies in the unit of theory, diagnostic/measurement, and praxis, namely that CNS injury can partly be repaired, including urinary bladder functions, and the repair can partly be understood even at the neuron level of description in human.

It results from compression, stretch, ischemia, or direct trauma of the nerve during hip arthroplasty, self-retaining retractor use in pelvicoabdominal surgery, lithotomy positioning for anesthesia or labor, and other more rare causes. Decreasing incidence of this complication after abdominal and gynecologic surgery but increase in its absolute numbers after hip arthroplasty has emerged over the last decade. We describe two illustrative cases related respectively to lithotomy positioning and self-retaining retractor use. The variability in clinical presentation of iatrogenic femoral nerve lesions, some new insights in their diverse pathophysiology, and in the diagnostic and treatment options are discussed with an update from the literature.

Studies have examined the influence of pain and fatigue on movement characteristics, but few report spatial and temporal characteristics within- and between-dynamic movements. The combined influences of fatigue and pain on these parameters are examined here. A shoulder-injured group (PAIN) (intensity >3/10, duration >3 consecutive months) and an age-sex-matched control group (CTRL) (n = 16 in each) performed a repetitive reaching task to voluntary termination. Kinematics, heart rate, and muscle activity were recorded. Group comparisons were made at the beginning and end of task. Both pain and fatigue changed movement parameters with CTRL subjects adapting to fatigue with increased arm movement, while the PAIN group increased center of mass (CoM) and minimized shoulder movement. Fatigue was associated with decreased arm relative variability, while pain caused increased arm and decreased CoM relative variability. Time to peak velocity tended to indicate increased joint coupling in the CTRL group only. Together, this suggests that despite initial differences in movement strategies, both groups tend to move toward more fixed movement strategies at the end of the task. Those of CTRL are more fixed temporally and spatially (in the arm), whereas the PAIN group adaptations are primarily spatial in nature and appear to focus on controlling CoM. © 2010 Springer-Verlag.

The aim was to extend these observations to loaded motion by investigating muscle activation patterns in upward scapular rotator muscles (upper and lower trapezius and serratus anterior) hosting Latent Myofascial Trigger Points simultaneously with lesion-free synergists for shoulder abduction (infraspinatus and middle deltoid). This approach allowed examination of the effects of these lesions on both their hosts and their lesion-free synergists in order to understand their effects on the performance of shoulder abduction. Methods: Surface electromyography was employed to measure the timing of onset of muscle activation of the upper and lower trapezius and serratus anterior (upward scapular rotators), infraspinatus (rotator cuff) and middle deltoid (abductor of the arm) initially without load and then with light (1-4 kg) dumbbells. Comparisons were made between control (no Latent Trigger Points; n = 14) and Latent Trigger Point (n = 28) groups. Findings: The control group displayed a relatively stable sequence of muscle activation that was significantly different in timing and variability to that of the Latent Trigger Point group in all muscles except middle deltoid (all P < 0.05). The Latent Trigger Point group muscle activation pattern under load was inconsistent, with the only common feature being the early activation of the infraspinatus. Interpretation: The presence of Latent Trigger Points in upward scapular rotators alters the muscle activation pattern during scapular plane elevation, potentially predisposing to overuse conditions including impingement syndrome, rotator cuff pathology and myofascial pain. © 2010 Elsevier B.V.

Whether these changes can be modified with motor training remains unclear. Twenty volunteers with unilateral LBP were randomly assigned to cognitively activate the lumbar multifidus independently from other back muscles (skilled training) or to activate all paraspinal muscles with no attention to any specific muscles (extension training). Electromyographic (EMG) activity of deep (DM) and superficial multifidus (SM) muscles were recorded bilaterally using intramuscular fine-wire electrodes and that of superficial abdominal and back muscles using surface electrodes. Motor coordination was assessed before and immediately after training as onsets of trunk muscle EMG during rapid arm movements, and as EMG amplitude at the mid-point of slow trunk flexion-extension movements. Despite different intentions of the training tasks, the pattern of activity was similar for both. After both training tasks, activation of the DM and SM muscles was earlier during rapid arm movements. However, during slow trunk movements, DM and SM activity was increased, and EMG activity of the superficial trunk muscles was reduced only after skilled training. These findings show the potential to alter motor coordination with motor training of the lumbar paraspinal muscles in recurrent LBP. Perspectives: Changes in motor coordination differed between skilled and extension training during slows trunk movements. As identical patterns of muscle activity were observed between training protocols, the results suggest that training-induced changes in motor coordination are not simply related to the muscle activation, but appear to be related to the task. © 2010 by the American Pain Society.

In addition, peripheral impulse input may induce and maintain thermal and mechanical hyperalgesia of FM patients. If so, activity and rest may alternately enhance and diminish intensity of FM pain. However, the effects of exercise on pain are ambiguous in studies of FM. Whereas exercise-only studies demonstrated increased pain and hyperalgesia during and after physical activity, some exercise studies that included rest periods resulted in decreased FM pain and increased function. To further clarify these effects, we examined the effects of alternating exercise with rest on clinical pain and thermal/mechanical hyperalgesia of 34 FM patients and 36 age-matched healthy controls (NC). Using an ergometer, all subjects performed arm exercise to exhaustion twice alternating with 15-minute rest periods. Although strenuous muscle activity was reported as painful by most FM subjects, overall clinical pain consistently decreased during the rest periods. Additionally, FM subjects' pain sensitivity to mechanical pressure decreased after each exercise and rest session. Conclusion: Alternating strenuous exercise with brief rest periods not only decreased overall clinical pain of FM subjects but also their mechanical hyperalgesia. No prolonged worsening of overall FM pain and hyperalgesia occurred despite vigorous muscle activity. Our findings contribute further evidence that FM pain and hyperalgesia are at least partially maintained by muscle impulse input, and that some types of exercises may be beneficial for FM. Perspective: FM is a pain-amplification syndrome that depends at least in part on peripheral tissue impulse input. Whereas muscle activity increased overall pain, short rest periods produced analgesic effects. © 2010 by the American Pain Society.

Recently we observed adaptive changes in motor cortical organisation in patients with recurrent low back pain (LBP), which are linked to altered motor coordination. Although changes in motor coordination can be trained and are associated with improved symptoms and function, it remains unclear whether these training-induced changes are related to reorganisation of the motor cortex. This was investigated using the model of a delay in postural activation of the deep abdominal muscle, transversus abdominis (TrA) in 20 individuals with recurrent LBP. Subjects were allocated to either motor skill training that involved isolated voluntary contractions of TrA, or a control intervention of self-paced walking exercise for 2 weeks. Electromyographic (EMG) activity was recorded from TrA bilaterally using intramuscular fine-wire electrodes. Motor cortical organisation using transcranial magnetic stimulation (TMS) and postural activation associated with single rapid arm movements were investigated before and after training. Motor skill training induced an anterior and medial shift in motor cortical representation of TrA, towards that observed in healthy individuals from our previous study. This shift was associated with earlier postural activation of TrA. Changes were not observed following unskilled walking exercise. This is the first observation that motor training can reverse reorganisation of neuronal networks of the motor cortex in people with recurrent pain. The observed relationship between cortical reorganisation and changes in motor coordination following motor training provides unique insight into potential mechanisms that underlie recovery. © 2009 European Federation of International Association for the Study of Pain Chapters.

The results indicate that there was no significant difference in the variance and in the change of variance over time of the exercise between the two groups when the participants were walking. However, when the participants were running, there was a significant difference between the two cohorts. While there was an increase in the variance over the duration of the exercise for both of the groups, the increase in variance of the LBP group was much greater (order of ten times) compared with that of the healthy participants. The difference between the two groups was also very significant when observing the change of variance over time. From these results, it is suggested that variance of SEMG of the muscles of the lower back, recorded when the participants are running, can be used to identify LBP patients.

A mistake in its recognition may have important consequences for the patients. As a result, the diagnosis must be considered very carefully in clinical practice. However, psychogenic movement disorders are not unusual, are mainly tremors, and a wrong diagnosis is common. Psychogenic is an unspecific term that usually masks the real mental disorder, and should be called somatoform disorders, factitious disorders, malingering, depression, anxiety and histrionic personality disorder, although the absence of a psychiatric diagnosis does not preclude a psychogenic cause. The diagnosis may often be difficult and should be made by an expert neurologist. Organic movement disorders must be excluded after a detailed neurological history, examination, and appropriate diagnostic studies. Psychogenic tremor is not only a diagnosis of exclusion, it can be diagnosed positively by its neurological signs, mainly: variability in frequency and amplitude, bilateral and sudden onset, non-progressive with frequent remissions, absence of finger, tongue or face tremor and coactivation of antagonistic muscles. Several tests can be useful in diagnosis, such as: accelerometry, EMG and response to placebo or suggestion. The treatment requires close cooperation between the medical team and patient. The problem must never be minimised and early diagnosis and treatment must be attempted. © 2010 Sociedad Espanola de Neurologia.

However, prolonged movement may lead to the development of painful injuries, because of the overload of low-threshold motor units. Especially in individuals with a pain condition, exercise prescription and the impact of fatigue is less clear. This may be because of the dual effects, aggravation and relief, which fatigue has on pain. The purpose of this review is to ascertain the relation between pain and the motor system, both in the development and management of pain. Recent studies show that fatigue alters pain-induced increases in corticomotor excitability and leads to within and between-muscle adaptations. Studies of acute pain have shown complex adaptations such as increased movement variability, which may be because of a search for motor solutions to prolong overall task performance. In contrast, chronic pain seems to limit movement duration, speed, and variability which could be protective in the short term but also counterproductive over time. Owing to these adaptations in movement strategies, pain chronicity may help to dictate exercise prescription. For example, the correct dosage of multimuscle, dynamic exercises would act to promote movement variability. Thus, it seems that exercise involving the use of different movement strategies could be effective in helping people to obtain exercise-induced benefits while avoiding injury and pain reaggravation. © 2010 by Lippincott Williams & Wilkins.

Moreover, muscle fatigue and discomfort are reported to play a relevant initiating role in WMSD. Aims: To investigate relationships between altered sensory information, i.e. localized muscle fatigue, discomfort and pain and their associations to changes in motor control patterns. Materials & Methods: In total 101 subjects participated. Questionnaires, subjective assessments of perceived exertion and pain intensity as well as surface electromyography (SEMG), mechanomyography (MMG), force and kinematics recordings were performed. Results: Multi-channel SEMG and MMG revealed that the degree of heterogeneity of the trapezius muscle activation increased with fatigue. Further, the spatial organization of trapezius muscle activity changed in a dynamic manner during sustained contraction with acute experimental pain. A graduation of the motor changes in relation to the pain stage (acute, subchronic and chronic) and work experience were also found. The duration of the work task was shorter in presence of acute and chronic pain. Acute pain resulted in decreased activity of the painful muscle while in subchronic and chronic pain, a more static muscle activation was found. Posture and movement changed in the presence of neck-shoulder pain. Larger and smaller sizes of arm and trunk movement variability were respectively found in acute pain and subchronic/chronic pain. The size and structure of kinematics variability decreased also in the region of discomfort. Motor variability was higher in workers with high experience. Moreover, the pattern of activation of the upper trapezius muscle changed when receiving SEMG/MMG biofeedback during computer work. Discussion: SEMG and MMG changes underlie functional mechanisms for the maintenance of force during fatiguing contraction and acute pain that may lead to the widespread pain seen in WMSD. A lack of harmonious muscle recruitment/derecruitment may play a role in pain transition. Motor behavior changed in shoulder pain conditions underlining that motor variability may play a role in the WMSD development as corroborated by the changes in kinematics variability seen with discomfort. This prognostic hypothesis was further, supported by the increased motor variability among workers with high experience. Conclusion: Quantitative assessments of the functional motor adaptations can be a way to benchmark the pain status and help to indentify signs indicating WMSD development. Motor variability is an important characteristic in ergonomic situations.

Facial EMG responses can be recorded with up to 95% NMB. FACE is a multi-channel EMG that quantifies the ratio of corrugator and orbicularis oculi muscle area activity to that in the frontalis muscle area and is used as an indicator of pain registration termed RATIO2. Methods and Results : Study 1: High and Low Fentanyl: 32 patients undergoing elective surgery randomly received either 50 mcg or 250mcg of fentanyl on induction. The high fentanyl induction group experienced 69% and 62.5% less activity in the corrugator and orbicularis oculi muscles respectively. The RATIO2 grimace response to surgical incision increased 96% in the low dose fentanyl group compared to the high dose. BIS values did not vary between the two groups. Study 2: Relationship to BIS: 16 patients undergoing elective surgery were monitored with both FACE and BIS monitors with no restrictions on anesthetic technique other than maintenance of NMB <95%. RATIO2 grimace responses were observed in 63% surgeries and bore no correlation to BIS response. Study 3: Facial grimacing relationship to pupillary dilation: 64 patients undergoing lower abdominal surgery were monitored every 15 minutes with pupillometry. Additional pupillometry was also performed if: Condition 1: RATIO2 > +20 for more than one minute, i.e. active grimacing, or, Condition 2: RATIO2 increased by 20, but absolute RATIO2 value remained under the zero point, i.e. no active grimacing. Pupillometry revealed increases in pupil size only when Condition 1 parameters were met (p=0.03). Study 4: Facial grimacing to incision as a function of clinical fentanyl dosing and desflurane concentration: 48 patients undergoing abdominal surgery were monitored with FACE. RATIO2 grimace data at incision were compared to desflurane concentration and fentanyl dosing. Quartile analysis was performed for a) induction fentanyl dosing and b) end-tidal desflurane. No significant differences were found between high and low quartiles. A separate quartile analysis of degree of RATIO2 grimace responses to surgical incision was performed for fentanyl and end tidal desflurane. No significant differences were observed. Individual patient variability to FACE grimace response to surgical incision appears to be only modestly related to fentanyl induction dosing and end tidal desflurane at time of incision. Discussion : We will examine whether facial grimacing during anesthesia contributes to post-operative exhaustion/malaise one week after general anesthesia.

Bursts of 150 square wave stimuli (duration: 152 ls; current intensity: 30% supramaximal) were applied. The stimulation frequency was increased from 4 pulses per second (pps) at increments of 2 pps until a cramp was induced. The number of cramps that could be elicited was smaller in flexor hallucis brevis than in abductor hallucis (16 vs. 22 out of 22 trials each; P < 0.05) and in the lateral gastrocnemius than in the medial gastrocnemius (5 vs. 20 out of 22 trials each; P < 0.0001). We show that leg and foot muscles have different cramp susceptibility, and the intermuscle variability in the elicitability profile for electrically induced cramps supports the use of the proposed method for cramp research. © 2009 Wiley Periodicals, Inc.

The aim of the present study was to determine the relationship between patients reported symptoms and clinical tests with electrodiagnostic findings. Three hundred and nine patients with a mean age of 48.35 +/- 12.26 (range = 19 - 81 years) participated. Patients were assessed clinically and electrophysiologically. The main outcome measures were CTS related symptoms of pain and paraesthesia, Tinel sign, Phalen's test, distal sensory latency, and distal motor latency. The symptoms of presence of pain and diurnal paraesthesia showed a statistical relationship with the distal sensory latency. No relationship was found between the Tinel sign and either the distal sensory latency or the distal motor latency. Furtheremore, no relationship could be shown between Phalen 60 s, Phalen 45 s and distal sensory and motor latency. The Phalen 30 s had a significant relationship with both sensory and motor distal latency. The findings of this study indicate that both related symptoms of pain, diurnal paraesthesia, and Phalen 30 s are associated with electrodiagnostic tests.

However, the influence of shoulder pain on muscle coordination of the shoulder has not been fully clarified. The aim of the present study was to examine the effect of experimentally induced shoulder pain on shoulder muscle function. Eleven healthy men (range 22-27 years), with no history of shoulder or cervical problems, were included in the study. Pain was induced by 5% hypertonic saline injections into the supraspinatus muscle or subacromially. Seated in a shoulder machine, subjects performed standardized concentric abduction (0degree-105degree) at a speed of approximately 120degree/s, controlled by a metronome. During abduction, electromyographic (EMG) activity was recorded by intramuscular wire electrodes inserted in two deeply located shoulder muscles and by surface-electrodes over six superficially located shoulder muscles. EMG was recorded before pain, during pain and after pain had subsided and pain intensity was continuously scored on a visual analog scale (VAS). During abduction, experimentally induced pain in the supraspinatus muscle caused a significant decrease in activity of the anterior deltoid, upper trapezius and the infraspinatus and an increase in activity of lower trapezius and latissimus dorsi muscles. Following subacromial injection a significantly increased muscle activity was seen in the lower trapezius, the serratus anterior and the latissimus dorsi muscles. In conclusion, this study shows that acute pain both subacromially and in the supraspinatus muscle modulates coordination of the shoulder muscles during voluntary movements. During painful conditions, an increased activity was detected in the antagonist (latissimus), which support the idea that localized pain affects muscle activation in a way that protects the painful structure. Further, the changes in muscle activity following subacromial pain induction tend to expand the subacromial space and thereby decrease the load on the painful structures. © 2009 Springer-Verlag.

Musculoskeletal conditions of the knee involve changes in sensorimotor function, but it is unclear whether these changes are a cause or result of pain. Induction of experimental pain may help solve this issue. Although this is commonly achieved by injection of hypertonic saline into muscle, muscle is commonly not the source of pain. This study investigated whether pain induced by injection of saline into the infrapatellar fat pad changes motor control of the quadriceps muscles of the knee. Methods. Ten participants performed a standardized task involving ascending and descending a series of steps. Electromyographic activity (EMG) of vastus medialis obliquus (VMO) and vastus lateralis (VL) was recorded with surface electrodes. Trials were conducted without pain, with anterior knee pain induced by injection (0.25 ml) of hypertonic saline (5%) into the infrapatellar fat pad, with anticipation of pain associated with unpredictable electrical shocks to the knee, and 20 minutes after pain cessation. EMG onset and amplitude were analyzed. Results. When participants ascended the steps with pain, the onset of VMO EMG was delayed relative to that of VL, in contrast to simultaneous or earlier activation of VMO EMG in the pre- and postpain trials. VL EMG amplitude was decreased significantly from the control condition. Conclusion. These data show that alterations in coordination of knee muscle activity can be caused by pain, even when it is of nonmuscle origin. Treatment of pain is therefore important to facilitate performance of the quadriceps muscles, which are essential for locomotor and functional tasks as well as for knee stability. © 2009, American College of Rheumatology.

Nowadays, four subtypes of dysferlinopathies have been established: limb-girdle muscular dystrophy 2B (LGMD 2B), Miyoshi myopathy (MM), distal anterior compartment type and scapuloperoneal type. We report a girl with dysferlinopathy with an unusual involvement of muscles in lower extremities and her brother whose symptoms started after the diagnosis of his sister. Both of them had lower limb weakness, marked elevation of serum creatine kinase (CK) levels and myopathic patterns in electromyography (EMG). Muscle biopsy of the girl who was diagnosed as having dysferlinopathy disclosed dystrophic changes and an absence of dysferlin. She had both proximal and distal weakness of the lower limbs presented in a 5-year-period. However her brother had difficulty only in foot dorsiflexion at the beginning of the symptoms. In conclusion, phenotypic variability, particularly at onset is one of the features of dysferlinopathies. To recognize and distinguish them from polymyositis is important to protect the patients from unnecessary treatment modalities. Recent imaging studies indicate that the pattern of muscular involvement is essentially uniform when both symptomatic and presymptomatic involvement is considered.

More than 30% of women have persistent pain 3 months after giving birth. There is no consensus regarding the pathology. However, coordination of muscle activity by appropriate timing and amplitude is necessary for maintaining adequate stability in the lumbopelvic area. The aim was to develop a method using surface electromyography to detect a feed-forward response in the pelvic floor muscles during limb movements performed at a comfortable speed applicable in future studies for women with lumbopelvic pain. Methods: Ten parous women with no lumbopelvic pain in the past 12 months were included. Surface electromyographic activity was recorded from the pelvic floor muscles and unilaterally from transversus abdominis/internal oblique, rectus abdominis, erector spinae, hip adductors, rectus femoris and deltoid. The subjects performed leg lift in supine and arm lift from standing. The electromyographic onset was related to the initiation of the movement. Findings: In the majority of the women the electromyographic onsets of the pelvic floor muscles occurred before the movement was initiated, regardless of whether it was a leg or an arm lift. In addition, electromyographic onsets for the other muscles, except the rectus abdominis during the arm lift, also occurred prior to the movements. Interpretation: The findings suggest a feed-forward response in the pelvic floor muscles during leg and arm lifts in women who had previously given birth and were without lumbopelvic pain. Movements performed at a comfortable speed seem to be useful in order to detect such a response. © 2008 Elsevier Ltd. All rights reserved.

A sustained decrease in the variability of anticipatory postural adjustments (APAs) occurs when performing cued arm raises following acute, experimentally induced low back pain (LBP; Moseley & Hodges, 2006). This observation implies that these changes in variability may also be relevant to people with chronic LBP. To confirm that this reduced variability in the timing of APAs is also evident in people with chronic LBP, the authors examined the standard deviations of electromyographic onset latencies from the bilateral internal oblique (IO) and erector spinae muscles (in relation to deltoid muscle onset) when 10 people with chronic LBP and 10 people without LBP performed 75 trials of rapid arm raises. The participants with LBP exhibited significantly less variability of their IO muscle onset latencies, confirming that the decreased variability of postural coordination that is evident following acutely induced LBP is also evident in people with chronic LBP. Thus, people with chronic LBP may be less capable of adapting their APAs to ensure postural stability during movement. © 2009 American Psychological Association.

Recently, there has been increased focus on defining biological aspects of neck pain. Studies have indicated that neurophysiological, biomechanical, and motor control abnormalities are present and may be useful either in prognosis or classification. We review some of these findings in the context of our own work defining biological markers that may form the basis for clinical tests that can be used for prognosis, classification, or outcome evaluation in patients with neck pain. We have identified abnormalities in neurophysiology using quantitative sensory testing (vibration, touch, and current perception) and response to cold provocation that are related to neck disability. We have identified altered muscle biochemistry by measuring circulating muscle proteins in a lumbar surgery model and are now applying those methods to whiplash injury. We have incorporated capnography into treatment to address central physiological changes present in some patients by monitoring and training CO2 levels. We have developed an innovative new test, the Neck Walk Index, that captures abnormal control of head movement during slow gait as a means of differentiating patients with neck pain from either unaffected controls or individuals with other pathologies. We have used time-varying 3-dimensional joint orientation kinematics to assess deficits in motor control during an upper extremity reach task, the results showing that poor coordination and control of the shoulder girdle leads to shoulder guarding and inconsistencies in elbow joint movement. Despite some promising early results, future research is needed to determine how these measures help clinicians to diagnose, evaluate, and forecast future outcome for patients who present with neck pain.

Training of deep abdominal muscles in isolation from the other trunk muscles, as an initial phase of training, has been shown to improve the timing of activation of the trained muscles, and reduce symptoms and recurrence of LBP. The aim of this study was to determine if training of the trunk muscles in a non-isolated manner can restore motor control of these muscles in people with LBP. Ten subjects with non-specific LBP performed a single session of training that involved three tasks: "abdominal curl up", "side bridge" and "birdog". Electromyographic activity (EMG) of trunk and deltoid muscles was recorded with fine-wire and surface electrodes during rapid arm movements and walking, before and immediately following the intervention. Onset of trunk muscle EMG relative to that of the prime mover (deltoid) during arm movements and the mean, standard deviation (SD) and coefficient of variation of abdominal muscle EMG during walking were calculated. There was no significant change in the times of onset of trunk muscle EMG during arm movements nor was there any change in the variability of EMG of the abdominal muscles during walking. However, the mean amplitude and SD of abdominal EMG was reduced during walking after training. The results of this study suggest that unlike isolated voluntary training, co-contraction training of the trunk muscles does not restore the motor control of the deep abdominal muscles in people with LBP after a single session of training. © 2007 Elsevier Ltd.

The test has revealed impairments in muscle function in younger/middle aged patients with various neck pain disorders. Neck pain and headache are common in elders but it is unknown if age alone affects performance in the CCFT. This study compared performance in the CCFT between healthy asymptomatic elderly and younger subjects. Electromyographic (EMG) amplitude in the sternocleidomastoid (SCM), angle of cranio-cervical flexion and ability to target the pressure levels of each test stage were examined in 44 elderly and 39 young participants. The results indicated that the elderly group had higher measures of normalized EMG signal amplitude in the SCM during the test (p < 0.001), greater shortfalls from the target pressures of all stages of the test (p < 0.01), except for the 22 mm Hg stage (p = 0.13), and larger variability of the cranio-cervical flexion range of motion for the five successive stages of the test (particularly at 26, 28 and 30 mm Hg stages) compared to young subjects. Clinicians must be aware of this occurrence when assessing performance in the CCFT in elders with neck pain. © 2008 Elsevier Ltd. All rights reserved.

The reflex can be obtained from every individual by electrophysiologic measures. There have been no reports concerning submental, orbicularis oris and masseter muscle reflex responses provoked by median nerve stimulation in healthy elderly individuals and patients with dementia up to now. Method: In the present study the median nerve was stimulated below the pain threshold and activities obtained from mental, submental, orbicularis oris and masseter muscles were recorded simultaneously in patients with dementia (n = 18) and in healthy elderly individuals (n = 18). Result: Latencies obtained from mental, submental, orbicularis oris and masseter muscles were approximately recorded within 80 - 100 milliseconds and the differences between the latencies were not statistically significant. Conclusion: The palmomental reflex seems to be an activity co-occurring with functions like mouth opening and swallowing, and reflecting hand - mouth reaction, rather than being only a primitive reflex involving mental muscle. We believe close temporal relationship among the activities of mental, submental, orbicularis oris and masetter muscles after hand stimulation requires these reflexes to be investigated in the physiology of hand and mouth coordination in further studies.

In this study, the impact of required forces in dynamic key touch pressure and key displacements on forearm extensor and flexor muscles was investigated. The aims were to evaluate the co-activation of forearm extensor and flexor muscles during a 2 min tapping task at 4 Hz and to assess possible changes in maximal surface electromyography (sEMG) activation during tapping using different keys with variable force-displacement characteristics. 13 subjects took part in the experiment and performed ten tapping sequences, using a different key make (with different force-displacement characteristics) each time. Two channels of sEMG were used to monitor forearm muscle activation. Results showed (a) that the co-activation of forearm extensor and flexor muscles increases with rising key makes force, and (b) that coordination between extensor and flexor muscles improves over time. The findings indicate that keyboards with make-force levels over 0.59 N are ergonomically inadequate. Differences in key displacement were less important. Relevance to industry: Chronic pain in the forearm due to repetitive tasks is common among employees working with computers.

Two aspects require consideration. First, hypertonic saline may have direct effects on axons other than small diameter pain fibres including the motoneurones that innervate the painful muscle. Second, it is unclear how force is maintained, when motoneurone discharge rate is decreased. We aimed to determine; (1) if motoneurone discharge rate is reduced during force-matched tasks when pain is induced in non-muscle tissue (to exclude direct effects on motoneurones) and (2) if the reduction of discharge rate is associated with additional changes in motoneurone recruitment over multiple muscle regions. Motoneurone discharge was recorded in the quadriceps with eight pairs of fine-wire electrodes. Seven subjects performed 30-s low-level, force-matched contractions before and during anterior knee pain, which was induced by a bolus (0.25 ml) injection of 5% hypertonic saline into the infra-patellar fat pad. In total, 119 motor units were identified. Of these, 34 were identified both before and during pain. The discharge rate of these units decreased during pain from 8.9(1.5) to 7.2(1.4) Hz (P < 0.0001). In addition, 31 units were recruited in the no-pain condition but not during pain, when 53 new units were recruited. These changes coincided with a large variability in gross muscle activity measures between muscle regions. These data confirm that motoneurone recruitment is altered when direct effects of saline on motoneurones are excluded. Recruitment of additional motor units may explain force maintenance despite reduced discharge rate of some units. © 2008 International Association for the Study of Pain.

Twenty-eight healthy subjects (range 22-44 years) performed a 90-min standardized task of correcting a text on a word-processor. Monetary reward was given according to productivity in order to induce time pressure. Pain intensity, general tension, and eye strain were reported on visual analogue scales before, during and after the computer session. Intramuscular trapezius blood fluxes were recorded by laser-Doppler flowmetry (LDF) and analyzed as % of baseline level. Muscle activity was measured from the upper trapezius and forearm extensors by surface electromyography (EMG), analyzed as % of a maximal calibration contraction, %EMGmax. Pain, tension, and eye strain increased considerably during the computer session with different time course for pain and tension. The LDF of the active side of trapezius was elevated for 30 min followed by a falling trend. There was an initial short-lasting increase in the inactive trapezius. The upper trapezius EMG was low (<3 % of EMGmax) but increased during the work, similar in both the active and passive side. There was a significant time and blood flux interaction effect on pain in the shoulders/neck, but no association with EMG. In conclusion, considerable neck/shoulder pain may develop in healthy pain-free subjects during 90 min of office-work and seems to be related to the regulation of trapezius muscle blood flow. © 2008 European Federation of Chapters of the International Association for the Study of Pain.

To test whether experimental pain also acts on the fusimotor system in humans, unitary recordings were made from 19 spindle afferents (12 Ia, 7 II) located in the ankle and toe extensors or peronei muscles of awake human subjects. Muscle pain was induced by bolus intramuscular injection of 0.5 ml 5% hypertonic saline into tibialis anterior (TA); skin pain was induced by 0.2 ml injection into the overlying skin. Changes in fusimotor drive to the muscle spindles were inferred from changes in the mean discharge frequency and discharge variability of spindle endings in relaxed muscle. During muscle pain no afferents increased their discharge activity: seven afferents (5 Ia, 2 II) showed a decrease and six (4 Ia, 2 II) afferents were not affected. During skin pain of 13 afferents discharge rate increased in one (Ia) and decreased in two (1 Ia, 1 II). On average, the overall discharge rate decreased during muscle pain by 6.1% (P < 0.05; Wilcoxon), but remained essentially the same during skin pain. There was no detectable correlation between subjective pain level and the small change in discharge rate of muscle spindles. Irrespective of the type of pain, discharge variability parameters were not influenced (P > 0.05; Wilcoxon). We conclude that, contrary to the 'vicious cycle' hypothesis, acute activation of muscle or skin nociceptors does not cause a reflex increase in fusimotor drive in humans. Rather, our results are more aligned with the pain adaptation model, based on clinical studies predicting pain-induced reductions of agonist muscle activity.

The interaction between muscle pain and motor control depends on the specific motor task. Muscle pain causes no increase in electromyographic activity at rest and reduces maximal voluntary contraction and endurance time during submaximal contractions. Furthermore, muscle pain causes an adaptive change in the coordination during dynamic exercises. Increased muscle activity reflecting reorganized muscle coordination and strategy is also a component of the functional adaption to muscle pain. In general, the "vicious cycle" hypothesis is not supported by these findings. Instead, they support an adaptive model predicting reduced agonistic muscle activity eventually advanced by changed antagonistic muscle activity. The motor control assessment procedures provide complementary clinical information and give further support for optimizing treatment regimens and prevention procedures for musculoskeletal pain. © Springer Science+Business Media, LLC 2008.

The study was conducted on eight asymptomatic subjects (Group C) and 20 subjects with articular TMD, randomly distributed over two groups: one treated using orofacial myofunctional therapy (OMT Group) and a control group with TMD (Group CTMD). Patient selection was based upon the Research Diagnostic Criteria for TMD (RDC/TMD). All subjects submitted to a clinical examination with self-reporting of symptom severity, and to orofacial myofunctional and electromyographic evaluation at diagnosis and again, at the end of the study. Correlations were calculated using the Pearson test and inter- and intragroup comparisons were made (p<0.05). In the diagnosis phase, subjects with TMD reported earache (65%), tinnitus (60%), ear fullness (90%), and 25% of the asymptomatic subjects reported tinnitus. The otologic symptoms were correlated with tenderness to palpation of the temporomandibular muscles and joints and with orofacial symptoms. Only the OMT group showed a reduction of otologic and orofacial symptoms, of tenderness to palpation and of the asymmetric index between muscles. OMT may help with muscle coordination and a remission of TMD symptoms. Copyright © 2008 by CHROMA, Inc.

Cross-sectional study. OBJECTIVE. To explore aspects of cervical musculoskeletal function in female office workers with neck pain. SUMMARY OF BACKGROUND DATA. Evidence of physical characteristics that differentiate computer workers with and without neck pain is sparse. Patients with chronic neck pain demonstrate reduced motion and altered patterns of muscle control in the cervical flexor and upper trapezius (UT) muscles during specific tasks. Understanding cervical musculoskeletal function in office workers will better direct intervention and prevention strategies. METHODS. Measures included neck range of motion; superficial neck flexor muscle activity during a clinical test, the craniocerivcal flexion test; and a motor task, a unilateral muscle coordination task, to assess the activity of both the anterior and posterior neck muscles. Office workers with and without neck pain were formed into 3 groups based on their scores on the Neck Disability Index. Nonworking women without neck pain formed the control group. Surface electromyographic activity was recorded bilaterally from the sternocleidomastoid, anterior scalene (AS), cervical extensor (CE) and UT muscles. RESULTS. Workers with neck pain had reduced rotation range and increased activity of the superficial cervical flexors during the craniocervical flexion test. During the coordination task, workers with pain demonstrated greater activity in the CE muscles bilaterally. On completion of the task, the UT and dominant CE and AS muscles demonstrated an inability to relax in workers with pain. In general, there was a linear relationship between the workers' self-reported levels of pain and disability and the movement and muscle changes. CONCLUSION. These results are consistent with those found in other cervical musculoskeletal disorders and may represent an altered muscle recruitment strategy to stabilize the head and neck.

Methods: Mandibular mid-incisor point was tracked in 22 asymptomatic subjects during standardized (at 2.2 mm/s) protrusion, contralateral excursion, and open jaw movements, as well as free, right-sided chewing and chewing standardized for timing (900 mslcycle). Tonic infusion of 4.5% hypertonic saline into the right masseter muscle maintained pain intensity between 30 and 60 mm on a 100-mm visual analog scale. Subjects performed tasks in 3 sessions on the same experimental day: control condition (baseline trials), test condition 1 (during hypertonic or 0.9% isotonic saline infusion), and test condition 2 (during isotonic or hypertonic saline infusion). Results: In comparison with control, there were no significant effects of hypertonic saline infusion on amplitude or velocity for protrusion or contralateral jaw movements or on velocity for jaw opening. Jaw-opening amplitude was significantly smaller in comparison with control during hypertonic, but not isotonic, saline infusion. During free but not standardized chewing, subjects chewed faster and exhibited larger amplitude gapes during hypertonic and isotonic infusion in comparison with control. Therefore, it was unlikely that pain had an effect on the kinematic parameters of jaw movement during free chewing. Qualitatively, individual subject data revealed considerable variability in the effects of hypertonic saline on movement parameters, which suggests that the effect of pain on jaw movement may not be uniform between individuals. Conclusions: The data indicate that the effect of pain on jaw movement may vary with the task performed.

Subjects were 40- to 65-year-old female caregivers divided into novice and experienced groups. Subjects from both groups performed home-care repositioning techniques on bedridden patients while muscle activity was recorded via electromyogram. Recordings were made from four muscles on the subjects' dominant side: the latissimus dorsi, the biceps brachii, the erector spinae, and the rectus femoris. The subjective burden involved in repositioning was also assessed using the rate of perceived exertion (RPE) and visual analog scales (VAS). Rectus femoris percentage of maximum voluntary contraction (%MVC) values were significantly lower than latissimus dorsi, erector spinae, and biceps brachii values in the novice group. %MVC values from the latissimus dorsi and biceps brachii were significantly higher among the novice group compared to the experienced group. RPE ratings from the novice group were significantly higher than those of the experienced group, and there was a non-significant trend for higher VAS values for the low back, arms, and legs in the novice group compared to the experienced group. Novice caregivers tended to change the patient's position by pulling with the upper limbs without using the lower limbs. In contrast, experienced caregivers exerted less energy by communicating with the patient and utilizing the patient's own movements. They used large, distributed muscle groups that effectively harnessed body mechanics and prevented excess exertion.

Anterior knee pain (AKP) is a common musculoskeletal complaint. It has been suggested that one factor that may contribute to the presence of AKP is a delay in the recruitment of the vastus medialis oblique muscle (VMO) relative to the vastus lateralis muscle (VL). There is however little consensus within the literature regarding the existence or nature of any such delay in the recruitment of the VMO within the AKP population. The purpose of this systematic review and meta-analysis was to examine the relative timing of onset of the VMO and VL in those with AKP in comparison to the asymptomatic population. Methods. The bibliographic databases AMED, British Nursing Index, CINAHL, EMBASE, Ovid Medline, PEDro, Pubmed and the Cochrane Library were searched for studies comparing the timing of EMG onset of the VMO and VL in those with AKP versus the asymptomatic population. Studies fulfilling the inclusion criteria were independently assessed. Heterogeneity across the studies was measured. A meta-analysis of results was completed for those studies where adequate data was supplied. Where comparable methodologies had been used, results were pooled and analysed. Results. Fourteen studies met the inclusion criteria; one prospective and thirteen observational case control. Eleven compared VMO and VL EMG onset times during voluntary active tasks while four investigated reflex response times. All used convenience sampling and did not state blinding of the assessor. Study methodologies/testing and assessment procedures varied and there was considerable heterogeneity within individual samples. Whilst a trend was identified towards a delay in onset of VMO relative to the VL in the AKP population during both voluntary active tasks and reflex activity, a substantial degree of heterogeneity across the pooled studies was identified (I2 = 69.9-93.4%, p < 0.01). Conclusion. Findings are subject to substantial and unexplained heterogeneity. A trend was demonstrated towards a delayed onset of VMO relative to VL in those with AKP in comparison to those without. However not all AKP patients demonstrate a VMO-VL dysfunction, and this is compounded by normal physiological variability in the healthy population. The clinical and therapeutic significance is therefore difficult to assess. © 2008 Chester et al; licensee BioMed Central Ltd.

The aim of this study was to investigate the electromyographic (EMG) activity in jaw muscles after third molar surgery to obtain more insight into the mechanisms of restrictions in jaw opening. Twenty subjects were examined before, 24 h and 1 week after surgery. Ten healthy controls were subjected to the same examination at two different occasions for intersession variability. The EMG activity of the masseter and anterior digastricus muscles was recorded at different jaw positions and during maximum voluntary clenching. Pain intensity was assessed at rest and during movements. The EMG activity in the jaw muscles increased with opening level (P < 0.01), but did not change after surgery. In contrast, the EMG activity during clenching was decreased in all muscles after surgery (P < 0.05). The pain intensity after surgery increased with jaw opening level (P < 0.001), but was in general not correlated to EMG level. Pain intensity during clenching was increased after surgery (P < 0.001), but not correlated to EMG level. The EMG activity did not change between visits in the control group. In conclusion, the results indicate that third molar surgery does not influence the EMG activity in the masseter and anterior digastricus muscles during various levels of static jaw opening, but decreases the EMG activity during clenching. However, these changes are not influenced by pain intensity. The results have implications for the understanding of the phenomenon of trismus. © 2007 The Authors.

Neurological complications resulting from ankle arthroscopy have been well documented in orthopaedic and podiatric literature. Owing to the superficial location of the ankle joint and the abundance of overlying periarticular neurovascular structures, complications reported in ankle arthroscopy are greater than those reported for other joints. In particular, all reported neurovascular injuries following ankle arthroscopy have been the direct result of distractor pin or portal placement. The standard posteromedial portal has recognized risks because of the proximity of the posterior neurovascular structures. There can be considerable variability in the course of these portals and their proximity to the neurovascular structures. We found one report of intra-articular damage to the posterior tibial nerve as a result of ankle arthroscopy in the English-language literature and we report this paper as a second case described in the literature. © Springer-Verlag 2007.

Activation characteristics of trunk muscles during cyclic upper-body perturbations caused by an oscillating pole. Objective: To evaluate the effect of a new device on trunk muscle activation. Design: Cross-sectional survey of trunk muscle activation characteristics. Setting: Physiologic laboratory at university institute. Participants: Thirty healthy subjects (15 men, 15 women) were recruited from a university campus. Interventions: A simple flexible pole that applies rapidly alternating forces on the trunk when set into motion was used. The device was held horizontally in both hands, in front of the body. It was used at 3 different oscillation frequencies (3, 3.5, 4.5Hz), in horizontal and vertical plane, respectively. Main Outcome Measures: Surface electromyography of 5 trunk muscles was measured and the data were normalized according to relative cycle time. Time dependent (amplitude curve) and time independent (mean amplitude over cycle) parameters were used for analysis. Results: Rectus abdominis and external oblique muscle amplitudes were directly proportional with oscillation frequency (analysis of variance), and these effects were independent of sex. Multifidus amplitude levels were subject to oscillation plane with increased levels for vertical oscillation in men but not in the women. All abdominal muscles exhibited continuous activation pattern, independent of oscillation plane. Back muscles changed from a continuous activation in horizontal plane into similarly phasic patterns in vertical oscillation plane. The occurring amplitude peak moved forward in relative cycle with increasing oscillation frequency. Conclusions: Back muscle activation patterns were subject to oscillation plane. Abdominal muscle activation was independent from oscillation frequency and oscillation plane. These normative data may be used to identify disturbed trunk muscle coordination patterns and to control success of functional restoration during rehabilitation interventions of back pain patients. © 2008 American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.

The aim of this study was to test the relevance of this type of EMG analysis. Methods: Healthy subjects (44 men and 13 women) and patients with chronic low back pain (57 men) performed three 7 s static ramp extension contractions ranging from 0% to 100% of the maximal voluntary contraction while standing in a static dynamometer. A subgroup of 20 healthy men also performed 5 s step contractions at 10%, 20%, 40%, 60% and 80% of the maximal voluntary contraction. Finally, to assess reliability, another subgroup (n = 20 healthy and 20 men with chronic low back pain) performed the protocol three times, on different days. Surface EMG signals were collected from four pairs of back muscles and subcutaneous tissue thickness was measured at the corresponding electrode sites. EMG amplitude values were computed at each 5% force level from 10% to 80% of the maximal voluntary contraction. Then, EMG-ratios were computed between different electrode sites and averaged bilaterally. Findings: All EMG-ratios were affected by the force level and the contraction type (ramp vs step contractions). Statistically significant Pearson's correlations (r = -0.38 to -0.57) were obtained between some EMG-ratios and their corresponding subcutaneous tissue thickness ratios. The reliability of the EMG-ratio variables ranged from moderate to excellent (intra-class correlation coefficients between 0.50 and 0.91). Comparisons between 12 men and 13 women and between 24 healthy men and 57 men with chronic low back pain showed that EMG-ratios were sensitive to sex but not to pain status. Multivariate analyses applied on the EMG-ratios identified clusters of subjects but none of the main clinical variables were able to clearly characterize these clusters. Interpretation: Overall, even though additional research is warranted to further substantiate some important psychometric characteristics of the EMG-ratios as well as their biomechanical and clinical significance, these results support their use for assessing the coordination patterns of back muscles, provided that confounding variables such as the force level, the contraction type, and subcutaneous tissue thickness are accounted for. © 2008 Elsevier Ltd.

We know little about how people with MMC optimize their walking balance. Recently, researchers have argued that medial-lateral control of gait requires more active neural input than the anterior-posterior direction, which is more passive. Our goal was to investigate the effect of providing external lateral stabilization (ELS) on walking patterns in people with MMC. We examined 12 people with MMC who could perform at least 4-6 independent steps. We found that the normalized step width (SW) was decreased 20% from without stabilizer to with stabilizer, where as the normalized step length (SL) was increased 4.17% from without stabilizer to with stabilizer. The ELS resulted in 25.10% reduction in centre of mass (COM) ranges of motions in the medial-lateral direction and 13.43% reduction in pelvic range of motions in the frontal plane. Our results suggested that by decreasing the medial-lateral control demands in people with MMC, we could improve gait with smaller SW, longer SL as well as reduced COM and pelvic ranges of motion in the frontal plane. In addition, ELS decreased energy cost and muscle co-activation of soleus and vastus lateralis that may help in diminishing the chances of pain and fatigue in people with MMC. Exploring the effect of the ELS provided us information that might be used to increase mobility safety and to develop a superior rehabilitation intervention for people with MMC. © 2008 Elsevier Ltd.

In an experimental part, acute muscle pain was induced in healthy subjects by intramuscular injection of hypertonic saline in trapezius (n = 10) and infraspinatus (n = 10) muscles. In a clinical part, workers with (n = 12) and without (n = 6) chronic neck-shoulder pain were compared. Cycle-to-cycle standard deviations of task duration, arm and trunk movement in 3D and surface electromyographic (EMG) root mean square activity were computed to assess the degree of variability. The variability in task timing increased in presence of both experimental and chronic pain (P < 0.05) compared with non-painful conditions. Experimental pain increased the variability of the starting position of the arm (P < 0.05), the arm range of motion (P < 0.01), the arm and trunk movement area (P < 0.01) and the acceleration of the arm (P < 0.01). In the chronic pain condition, the variability of arm and trunk acceleration (P < 0.01) and EMG activity (P < 0.05) was decreased compared with healthy controls. These results indicate that pain alters the magnitude of motor variability, and that the transition from acute to chronic pain is accompanied by changes in motor patterns. Experimental pain likely resulted in a quest for a motor solution reducing nociceptive influx, while chronic pain was characterised by a diminished motor flexibility. © 2007 Springer-Verlag.

This study evaluated activation of those muscles in specific exercises. Hypothesis: Specific exercises will activate key scapular-stabilizing muscles in clinically significant amplitudes and patterns. Study Design: Controlled laboratory study. Methods: Muscle activation amplitudes and patterns were evaluated in the serratus anterior, upper trapezius, lower trapezius, anterior deltoid, and posterior deltoid muscles with electromyography in symptomatic (n = 18) and asymptomatic (n = 21) subjects as they executed the low row, inferior glide, lawnmower, and robbery exercises. Results: There were no significant differences in muscle activation amplitude between groups. Muscle activation was moderate across all of the exercises and varied slightly with the specific exercise. The serratus anterior and lower trapezius were activated between 15% and 30% in all exercises. Upper trapezius activation was high (21%-36%) in the dynamic exercises (lawnmower and robbery). Serratus anterior was activated first in the low row and last in the lawnmower and robbery. The upper trapezius and lower trapezius were activated first in the lawnmower and robbery. Conclusion: These specific exercises activate key scapular-stabilizing muscles at amplitudes that are known to increase muscle strength. Clinical Relevance: These exercises can be used as part of a comprehensive rehabilitation program for restoration of shoulder function. They activate the serratus anterior and lower trapezius-key muscles in dynamic shoulder control-while variably activating the upper trapezius. Activation patterns depended on scapular position resulting in variability of amplitude and activation sequencing between exercises. Inferior glide and low row can be performed early in rehabilitation because of their limited range of motion, while lawnmower and robbery, which require larger movements, can be instituted later in the sequence. © 2008 American Orthopaedic Society for Sports Medicine.

Delayed and/or reduced activity of vastus medialis obliquus (VMO) and different movement patterns have been identified in individuals with PFP in some studies, whereas other studies have failed to show a difference compared to non-affected controls. The discrepancy between study results may depend on the different tasks that have been investigated. No previous study has investigated these variables in postural responses to unpredictable perturbations in PFP. Whole body three dimensional kinematics and surface EMG of quadriceps muscles activation was studied in postural responses to unpredictable support surface translations in 17 women with PFP who were pain free at the time of testing, and 17 matched healthy controls. The results of the present study showed earlier onset of VMO activity and associated changes in kinematics to anterior platform translation in the PFP subjects. We suggest that the relative timing between the portions quadriceps muscles may be task specific and part of an adapted response in attempt to reduce knee joint loading. This learned response appears to remain even when the pain is no longer present. © 2006 Elsevier Ltd. All rights reserved.

Ankle sprains can be prevented by external ankle supports and proprioceptive-coordination training, especially in athletes with previous ankle sprains. Proprioception is a broad concept that includes balance and postural control with visual and vestibular contributions, joint kinesthesia, position sense, and muscle reaction time. Proprioceptive feedback is crucial in the conscious and unconscious awareness of a joint or limb in motion. Enhancement of functional joint stability by proprioceptive (or neuromuscular) training is important both in prevention and rehabilitation of athletic injuries. © 2008 Elsevier Inc.

Electromyographic (EMG) and kinematics data from two previous studies were re-analysed. Newly employed butchers were followed prospectively in relation to employment duration and pain development. Healthy butchers with long-term experience were compared with novices. The variability of the cycle time, EMG ratio and arm and trunk movement was expressed as cycle-to-cycle standard deviations. During the first 6 months of employment, cycle time variability decreased, while posture and movement variability increased (p < 0.05). In presence of pain, the variability of the initial arm position decreased while it increased for the trunk (p < 0.05). Experienced butchers showed a larger variability than novices for work cycle and several kinematic variables, but a smaller EMG ratio variability (p < 0.05). These findings indicate that the variability of motor patterns in repetitive work changes with experience and pain.

To test whether experimental pain also acts on the fusimotor system in humans, unitary recordings were made from 19 spindle afferents (12 Ia, 7 II) located in the ankle and toe extensors or peronei muscles of awake human subjects. Muscle pain was induced by bolus intramuscular injection of 0.5 ml 5% hypertonic saline into tibialis anterior (TA); skin pain was induced by 0.2 ml injection into the overlying skin. Changes in fusimotor drive to the muscle spindles were inferred from changes in the mean discharge frequency and discharge variability of spindle endings in relaxed muscle. During muscle pain no afferents increased their discharge activity: seven afferents (5 Ia, 2 II) showed a decrease and six (4 Ia, 2 II) afferents were not affected. During skin pain of 13 afferents discharge rate increased in one (Ia) and decreased in two (1 Ia, 1 II). On average, the overall discharge rate decreased during muscle pain by 6.1% (P < 0.05; Wilcoxon), but remained essentially the same during skin pain. There was no detectable correlation between subjective pain level and the small change in discharge rate of muscle spindles. Irrespective of the type of pain, discharge variability parameters were not influenced (P > 0.05; Wilcoxon). We conclude that, contrary to the 'vicious cycle' hypothesis, acute activation of muscle or skin nociceptors does not cause a reflex increase in fusimotor drive in humans. Rather, our results are more aligned with the pain adaptation model, based on clinical studies predicting pain-induced reductions of agonist muscle activity. © 2008 The Authors.

It has yet to be used to assess voluntary activation in trunk muscles. The aim of this study was to assess the feasibility of using TMS to measure voluntary activation in back muscles. Methods: Sixteen healthy subjects performed a series of brief maximal and submaximal isometric contractions of the back extensors during which TMS was delivered to the motor cortex. The evoked (superimposed) twitch was measured using dynamometry and simultaneous surface electromyographic (EMG) recordings were taken from the left and right erector spinae at vertebral level T12. Voluntary activation was derived using the expression: (1-superimposed twitch amplitude/resting twitch amplitude) x 100. The resting twitch amplitude was estimated by extrapolation of the linear correlation between voluntary torque and superimposed twitch amplitude to zero torque. Results: The relationship between superimposed twitch size and voluntary contraction strength for contraction strengths of 50-100% MVC was linear but regression revealed variability between subjects. When data were included from those subjects with a good linear regression fit a strong linear relationship was found for the group means between voluntary contraction strength and voluntary activation (r2 = 1) and superimposed twitch size (r2 = 0.99) for contraction strengths of 50-100% MVC. Voluntary activation was found to be less than maximal (67.71 +/- 5.22%) during maximal efforts. Time-to-peak amplitude decreased linearly with increasing voluntary torque. The amplitudes of the motor evoked potentials (MEPs) increased with increasing voluntary torque. Conclusions: Twitch interpolation using TMS can be used to quantify voluntary activation in back extensors. The results of this study reveal that neural drive to the back extensors during strong contractions is submaximal. Significance: The assessment of voluntary activation of the back muscles may aid our understanding of the mechanisms of alteration in control of these muscles implicated in chronic low back pain. © 2008 International Federation of Clinical Neurophysiology.

Design: A cross sectional survey of 30 healthy volunteers was executed. The task was to maintain position and motion of a flexible pole that was set into oscillation. Oscillations were applied at three frequencies (3, 3.5, 4.5 Hz), in horizontal and vertical directions. SEMG signals of five trunk muscles were measured. Co-ordination was assessed by calculating mean relative amplitudes and mean, as well as, grand averaged muscle ratios during oscillation cycle for front over back (F/B), internal over external oblique (OI/OE), and multifidus over erector spinae (MF/ES) muscles. Results: Vertical oscillation evoked increased mean MF relative amplitudes and mean F/B and MF/ES muscle ratios in comparison with horizontal oscillation. Grand averaged F/B ratio was phase shifted about 180degree of relative cycle between both oscillation directions. With increasing oscillation frequency mean F/B ratio increased, but OI/OE ratio decreased. Amplitude range of grand averaged muscle ratios during oscillation cycle was augmented with increasing frequency. Conclusions :The gathered normative data can serve as an initial data basis for further investigations on low back pain patients. Relative to oscillation direction and frequency, demands on trunk muscles vary from primarily stabilizing towards mobilizing activities. © 2007 IOS Press. All rights reserved.

Purpose: The main objective of the present study was to evaluate if subjects with WADs can produce isometric neck extension and flexion forces with precision, variability, and a mode of control similar to the values of healthy subjects. Study design: A control group study with repeated measures. Patient samples: Neck force production parameters and neuromuscular control were measured in 17 whiplash and 14 control subjects. The experimental group included subjects who had a history of persistent neck pain or disability after a motor vehicle accident. Outcome measures: Pain levels were assessed on a standard 100-mm visual analog pain scale at the beginning and end of the experiment. Each whiplash subject completed the neck disability index and the short-form 36 health survey (SF-36) questionnaire before the experiment. Methods: All subjects were asked to exert flexion and extension forces against a fixed head harness. Kinetic variables included time to peak force, time to peak force variability, peak force variability, and absolute error in peak force. Surface electrodes were applied bilaterally over the sternocleidomastoideus and paraspinal muscles. Electromyography (EMG)-dependent variables included EMG burst duration and amplitude using numerical integrated techniques. Results: The average time to peak force was significantly longer for whiplash subjects than for the healthy controls. A significant increase in peak force variability was also observed in the whiplash group, and no group differences were noted for absolute error. Heightened muscular activity was seen in both paraspinal muscles, even though it only reached statistical significance for the left paraspinal muscle. Conclusion: Our results show that the whiplash subjects involved in the study were able to produce isometric forces with spatial precision similar to healthy controls using a motor strategy in which the time to peak force is increased. This trade-off between spatial precision and time to peak force probably reflects an adaptation aimed at limiting pain and further injuries. © 2007 Elsevier Inc. All rights reserved.

Surface EMG signals were detected from nine healthy subjects from the upper, middle and lower divisions of trapezius during a repetitive bilateral shoulder flexion task. Measurements were performed before and after injection of 0.5 ml hypertonic (pain condition) and isotonic (control) saline into the upper division of the right trapezius muscle in two experimental sessions. On the painful side, upper trapezius showed decreased EMG amplitude (average rectified value, ARV) and lower trapezius increased ARV throughout the entire task following the injection of hypertonic saline (40.0 +/- 22.2 vs. 26.0 +/- 17.4 muV, and 12.5 +/- 7.6 vs. 25.6 +/- 14.8 muV, respectively, at the beginning of the contraction). On the side contralateral to pain, greater estimates of ARV were identified for the upper division of trapezius as the task progressed (37.4 +/- 20.2 vs. 52.7 +/- 28.4 muV, at the end of the contraction). Muscle fiber conduction velocity did not change with pain in all three divisions of the right trapezius muscle. The results suggest that local elicitation of nociceptive afferents in the upper division of the trapezius induces reorganization in the coordinated activity of the three subdivisions of the trapezius in repetitive dynamic tasks. © 2006 Springer-Verlag.

Methods: A control group study with repeated measures was performed. Study participants included 15 control subjects and 14 patients with LBP. Participants were required to exert 50% and 75% of their maximal trunk flexion and extension. In a learning phase, feedback was provided, after which study participants were asked to perform 10 trials without any feedback. Spatiotemporal parameters of muscular activity and force production were recorded. Dependent variables included time to peak force, peak force variability, absolute error in peak force, electromyogram (EMG) burst duration for agonist muscles, and normalized integrated EMG. Results: Average time to peak force was significantly longer for subjects with LBP than for healthy subjects. Subjects with LBP showed longer burst duration for all 4 muscles recorded. No group difference was noted in normalized integrated EMG. Conclusions: We suggest that the observed changes in trunk motor control and trunk muscle recruitment strategies are not only mediated by a neurophysiologic adaptation to chronic pain but also by cognitive adaptations modulated by fear of movement and fear of reinjury. © 2007.

A cross-sectional study of the timing of trunk muscle activations between 19 participants with chronic low back pain (LBP) compared with 19 matched controls. OBJECTIVE. To determine the effects of target height and load on trunk muscle coordination in whole body reaching tasks, and whether participants with chronic LBP display a shift in trunk muscle coordination performing these tasks. SUMMARY OF BACKGROUND DATA. Changes in the precise timing of trunk muscle activation may cause an initial episode of back pain, or contribute to the development of recurrent or chronic symptoms. However, most paradigms used to examine timing of trunk muscle activation did not necessitate large displacements of the trunk. METHODS. Participants with and without chronic LBP performed a series of bilateral reaching tasks to 3 target heights with 3 different loads held in the reaching hands. During reaching, joint motions were recorded with an optoelectric system and surface electromyographic signals were collected bilaterally from 5 trunk muscles: rectus abdominis, external oblique, internal oblique, iliocostalis lumborum, and the multifidis, and bilaterally from the deltoid muscle. The onset latencies of the antagonist trunk muscles relative to the deltoid muscle were analyzed to determine the effects of group, target height and load. RESULTS. Onset of trunk extensor muscles was significantly delayed in participants with chronic LBP compared with control subjects. Further, the onset latency of the antagonist trunk muscles increased with target distance, but decreased with target load. CONCLUSION. These findings suggest that a well documented control strategy generalizes beyond single joint movements and that individuals with chronic LBP display a shift in this strategy. © 2007 Lippincott Williams & Wilkins, Inc.

Twenty healthy controls, 21 WMSD and 20 WAD patients with non-acute neck-shoulder pain were recruited for this cross-sectional study. Surface electromyography (sEMG) recordings were performed at the upper trapezius muscles during reference contractions, standardised computer tasks (typing and unilateral stress task), and rest measurements. sEMG was continuously recorded during these measurements. Outcome measures were root mean square (RMS) to study muscle activity, and relative rest time (RRT) to study muscle relaxation. Statistical analysis comprised the bootstrap technique and Kruskall-Wallis tests. Results showed no clear evidence for abnormal muscle activation patterns in WMSD and WAD patients compared to healthy controls. However, a tendency was observed for higher RMS levels during the reference contractions and computer tasks in both patient groups compared to healthy controls, and lower RRT levels at the non-dominant side during stress. Both patient groups also showed larger variability in RMS and RRT values. This variability has more often been reported in literature and may suggest the existence of subgroups of pain patients with corresponding different muscle activation patterns not related to aetiology. Future research may focus on identifying these subgroups of patients with neck-shoulder pain. © Springer-Verlag 2006.

They hypothesized that activity in VMO would be more delayed and decreased in CKC tasks than in OKC tasks. Women with PFP (n = 17) and healthy controls (n = 17) performed isometric quadriceps contractions in CKC and OKC tasks. The authors manipulated only the application of resistance. Electromyographs (EMGs) showed that participants with PFP reacted later and activated the quadriceps more in the CKC task but had intramuscular quadriceps coordination similar to that of controls. The nature of the OKC task or the CKC task does not seem to explain contradictory findings regarding VMO activation. Copyright © 2007 Heldref Publications.

DESIGN: Examiner differences on single-segment paraspinal mapping scores and other findings were examined in a prospective, masked, double-controlled trial involving 150 people aged 55-80 yrs who were selected for no symptoms, back pain, or possible spinal stenosis. RESULTS: Unmasked clinicians were more variable than masked physicians (F2,219 = 4.808, P =<0.01) and gave lower scores to people they felt had mechanical back pain. The percentage of inadequate segmental scores differed among clinicians (0-16.6%, F8,226 = 4.170, P < 0.001), with fellows having more difficulty than faculty (11.76 +/- 32.38% vs. 0.75 +/- 8.67%) (t233 = 3.753, P < 0.001). Correction of clinician bias improved the relationship between paraspinal score and subjects' ability to walk (weighted regression R = 0.129, B = -0.047, P < 0.001; unweighted regression R = 0.090, B = -0.045, P < 0.001). CONCLUSIONS: Objective testing is adversely affected by clinician factors including prejudgment, experience, and individual idiosyncrasies. Less variation is found in more codified procedures. For electrodiagnostic consultation, correction of variability improves the relationship of test results to disability. © 2007 Lippincott Williams & Wilkins, Inc.

We extended these findings to the double-joint, shoulder-elbow system in these patients. Ten non-disabled individuals and 11 stroke survivors with spasticity in upper limb muscles participated. Stroke survivors had sustained a single unilateral stroke 6-36 months previously, had full pain-free passive range of motion of the affected shoulder and elbow and had some voluntary control of the arm. EMG activity from four elbow and two shoulder muscles was recorded during quasi-static (<5degree/s) stretching of elbow flexors/extensors and during slow voluntary elbow flexion/extension movement through full range. Stretches and active movements were initiated from full elbow flexion or extension with the shoulder in three different initial positions (60degree, 90degree, 145degree horizontal abduction). SRTs were defined as the elbow angle at which EMG signals began to exceed 2SD of background noise. SRT angles obtained by passive muscle stretch were compared with the angles at which the respective muscles became activated during voluntary elbow movements. SRTs in elbow flexors were correlated with clinical spasticity scores. SRTs of elbow flexors and extensors were within the biomechanical range of the joint and varied with changes in the shoulder angle in all subjects with hemiparesis but could not be reached in this range in all healthy subjects when muscles were initially relaxed. In patients, limitations in the regulation of SRTs resulted in a subdivision of all-possible shoulder-elbow arm configurations into two areas, one in which spasticity was present ("spatial spasticity zone") and another in which it was absent. Spatial spasticity zones were different for different muscles in different patients but, taken together, for all elbow muscles, the zones occupied a large part of elbow-shoulder joint space in each patient. The shape of the boundary between the spasticity and no-spasticity zones depended on the state of reflex inter-joint interaction. SRTs in single- and double-joint flexor muscles correlated with the positions at which muscles were activated during voluntary movements, for all shoulder angles, and this effect was greater in elbow flexor muscles (brachioradialis, biceps brachii). Flexor SRTs correlated with clinical spasticity in elbow flexors only when elbow muscles were at mid-length (90degree). These findings support the notion that motor impairments after CNS damage are related to deficits in the specification and regulation of SRTs, resulting in the occurrence of spasticity zones in the space of elbow-shoulder configurations. It is suggested that the presence of spatial spasticity zones might be a major cause of motor impairments in general and deficits in inter-joint coordination in particular in patients with spasticity. © 2007 Springer-Verlag.

Spatial and temporal parameters of gait have clinical relevance in the assessment of motor pathologies, particularly in orthopaedics. However, the influence of gait speed on these biomechanical parameters has been difficult to be taken into consideration so far. The objective of the present study was to analyse the impact of gait speed on gait parameters and to set a standard walking speed for patients with osteoarthritis by means of a special treadmill control mechanism. The second objective is to compare the gait patterns in patients with unilateral osteoarthritis of the hip joint or of the knee joint to the gait pattern of healthy control subjects. A total of 20 patients with severe unilateral osteoarthritis of the hip, 20 patients with severe unilateral osteoarthritis of the knee and 20 healthy elderly subjects without any history of lower extremity joint pathology were investigated at four different gait speeds. The gait analysis equipment used consisted of an infinitely adjustable force-instrumented treadmill and an ultrasound-based motion analyser system with electromyography. Our data suggest that most of the biomechanical parameters depend on gait speed. The highest gait speed that all our patients with severe osteoarthritis were suitable with, without pain and loss of coordination, was 2.00 km/h. Our findings indicate that the changes in gait parameters may occur in patients with unilateral osteoarthritis of the hip joint or the knee joint compared to the gait pattern of healthy control subjects. Hip joint or knee joint degeneration was compensated for in part by the pelvis and other joints in the lower limb. Reduced motion of the hip joint or knee joint leads to an increased pelvic motion, which should affect the natural mobility of the lumbar spine and cause pain in the lumbar region of the spine because of their kinematic interaction. © Springer-Verlag 2005.

STUDY DESIGN: Two subjects meeting diagnostic criteria for vestibulodynia were treated with 20 units and 40 units of BTX/A at 12-week intervals. Outcomes included a visual analogue scale (VAS), weekly coital pain diaries, surface electromyography (sEMG) and a vulvar algesiometer. RESULTS: BTX/A modestly reduced coital pain in 1 patient and was ineffective in the other. Pelvic floor hypertonicity and variability were markedly reduced in both patients, but negligible changes occurred in vestibular hyperalgesia. The patient with greater pelvic floor tension had more of a reduction in diary-rated coital pain 2 weeks after the injection (29% vs. 9%) and on the VAS at 12 weeks (15% vs. 3%). CONCLUSION: BTX/A injections may be effective in reducing coital pain in vestibulodynia with levator ani tenderness but have little effect on vestibular allodynia. The relationship between pelvic floor hypertonicity and decreased coital pain suggests that vestibulodynia may be a variant of chronic regional pain syndrome. The dose and volume of BTX/A injected may be related to the degree of relief. © Journal of Reproductive Medicine, Inc.

Some useful parameters abstracted from 8-channel EMG signal in time-frequency domain are used or proposed and calculated in this paper to decrease this variability, when comparing the possible difference between low back pain patients and normal control group. The calculation of instantaneous median frequency is improved to decrease the interruption of background noise, and different power densities in EMG time-frequency spectrogram are observed in two tested groups.

Twenty individuals without temporomandibular disorder (TMD) pain participated in a biofeedback-training task to establish a relaxed baseline. They were instructed to clench their teeth according to their personal definition of the term, while EMG data were collected. This process was repeated two more times, followed by similar instructions to make minimal and maximal contact between the teeth. Results showed that individual subjects were very consistent in their behavioral definition of clenching and that the subjects taken as a whole showed markedly greater variability. The precise behavioral meaning of clenching varies across individuals. The failure to account for these individual differences may explain in part reported discrepancies on the role of parafunctions in TMD. Copyright © 2006 by Chroma, Inc.

However, there are conflicting data. Changes in motor unit firing may provide more definitive evidence. Synchronization of motor unit action potentials (MUAPs) in vastus medialis obliquus (VMO) and vastus lateralis (VL) may contribute to coordination in patellofemoral joint control. We hypothesized that synchronization may be reduced in AKP. Recordings of single MUAPs were made from VMO and multiunit electromyograph (EMG) recordings were made from VL. Averages of VL EMG recordings were triggered from the single MUAPs in VMO. Motor units in VL firing in association with the VMO motor units would appear as a peak in the VL EMG average. Data were compared to previous normative data. The proportion of trials in which a peak was identified in the triggered averages of VL EMG was reduced in people with AKP (38%) compared to controls (90%). Notably, although 80% of subjects had values less than controls, 20% were within normal limits. These results provide new evidence that motor unit synchronization is modified in the presence of pain and provide evidence for motor control dysfunction in AKP. © 2005 by the American Pain Society.

Various entropy algorithms have been used in clinical studies, but until now a commercially available monitor exists only for spectral entropy. By calculating two distinct values for the EEG dominated part of the spectrum (state entropy, SE) and the total spectrum (response entropy, RE), the M-Entropy module claims to provide useful information regarding the cortical state of the patient as well as an indirect measure of adequacy of analgesia. Generally, entropy has been studied for quantification of anaesthetic drug effect for various GABA-ergic i.v. induction agents and volatile anaesthetics like propofol and sevoflurane and overall was found comparable to the current clinical gold standard bispectral index (BIS). Entropy guidance may not be used during ketamine or nitrous oxide administration, since there is no reliable correlation to the patient's state of consciousness. The usefulness of RE as a surrogate for increased EMG activity due to painful stimulation has not been proven so far. © 2005 Elsevier Ltd. All rights reserved.

The perception of pain, and therefore, the need for analgesia, is individual, and the monitoring of analgesia is indirect and, in essence, of the moment. Under general anaesthesia, analgesia is continually influenced by external stimuli and the administration of analgesic drugs, and cannot be really separated from anaesthesia: the interaction between analgesia and anaesthesia is inescapable. Autonomic reactions, such as tachycardia, hypertension, sweating and lacrimation, although non-specific, are always regarded as signs of nociception or inadequate analgesia. Autonomic monitoring techniques, such as the analysis of heart rate variability, laser Doppler flowmetry, phlethysmographically derived indices and the pupillary light reflex, may help to quantitate reactions of the autonomic nervous system. For the past few years, automated electroencephalographic analysis has been of great interest in monitoring anaesthesia and could be useful in adapting the peroperative administration of opioids. A range of information collected from the electroencephalogram, haemodynamic readings and pulse plethysmography might be necessary for monitoring the level of nociception during anaesthesia.

The purpose of this study was to measure shoulder muscle coordination in patients with massive cuff tears, including the effect of subacromial pain suppression. Ten patients, with MRI-proven cuff tears, performed an isometric force task in which they were asked to exert a force in 24 equidistant intervals in a plane perpendicular to the humerus. By means of bi-polar surface electromyography (EMG) the direction of the maximal muscle activation or principal action of six muscles, as well as the external force, were identified prior to, and after subacromial pain suppression. Subacromial lidocaine injection led to a significant reduction of pain and a significant increase in exerted arm force. Prior to the pain suppression, we observed an activation pattern of the arm adductors (pectoralis major pars clavicularis and/or latissimus dorsi and/or teres major) during abduction force delivery in eight patients. In these eight patients, adductor activation was different from the normal adductor activation pattern. Five out of these eight restored this aberrant activity (partly) in one or more adductor muscles after subacromial lidocaine injection. Absence of glenoid directed forces of the supraspinate muscle and compensation for the lost supraspinate abduction torque by the deltoideus leads to destabilizating forces in the glenohumeral joint, with subsequent upward translation of the humeral head and pain. In order to reduce the superior translation force, arm adductors will be co-activated at the cost of arm force and abduction torque. Pain seems to be the key factor in this (avoidance) mechanism, explaining the observed limitations in arm force and limitations in maximum arm elevation in patients suffering subacromial pathologies. Masking this pain may further deteriorate the subacromial tissues as a result of proximal migration of the humeral head and subsequent impingement of subacromial tissues. © 2006 Elsevier Ltd.

Based on the hypothesis that trunk-pelvis coordination is linked to overall gait stability, persons with LBP can be expected to have difficulties in dealing with perturbations. We examined the ability of 12 persons with LBP and 12 controls to adapt trunk and pelvis rotations and ES activity to sudden changes in velocity. 3D angular movements of thoracic, lumbar, and pelvic segments and surface EMG were recorded during treadmill walking at six different velocities, which increased or decreased unexpectedly. Relative phases of segmental rotations were determined and (in-)variant properties of kinematics and ES activity were studied using principal component analysis. Compared to healthy controls, persons with LBP exhibited a reduced ability to adapt trunk-pelvis coordination and ES muscle activity to changes in velocity. Altered coordination and muscular control may reflect an attempt to stabilise the spine and prevent the occurrence of unexpected perturbations. The assessment of gait patterns in terms of coordination may help clinicians to quantify movement impairments and may suggest interventions aimed at facilitating the emergence of desired coordination patterns. © 2005 Elsevier B.V.

Co-contraction can control laxity and instability but may place constraints on the variability of the knee's motion during gait. Slight variation among gait cycles is normal, but reduced variability of joint motions could be detrimental. The purpose of this study was to quantify knee motion variability during gait and assess the influence of muscle activity, frontal plane laxity, and pain on knee movement variability in patients with medial knee OA. Methods: Fifteen subjects with unilateral medial knee OA and 15 age and gender matched uninjured subjects underwent gait analysis, with electromyography to compute co-contraction. Stress radiographs were obtained for measuring frontal plane laxity. Knee motion variability was assessed from the phase angle (knee angle versus angular velocity) during early stance. Results: Despite altered involved side knee kinematics and kinetics, individuals with knee OA showed involved side frontal plane variability which was not significantly different from the control group, but was significantly lower than the variability of the uninvolved knee's motion. Laxity and medial co-contraction influenced the amount of joint motion variability in the involved knee of the OA subjects. Pain did not influence variability. Conclusion: Patients with medial knee OA displayed altered involved knee kinematics and kinetics, although stride-to-stride variability of knee motion was unchanged. Evidence of excessive joint motion variability on the uninvolved side, however, may provide insight into the development of OA in the contralateral cognate joint. © 2005 Elsevier B.V.

DESIGN: A total of 28 healthy volunteers participated in this study: 14 in the repeatability study and 14 in the reproducibility study. Each subject was tested three times, with an interval of 1 wk between the test sessions. The intraclass correlation coefficients and the standard error of the measurements as a percentage of the grand mean were calculated. RESULTS: The intraclass correlation coefficients for both the repeatability and the reproducibility evaluation showed good to excellent reliability for all variables (intraclass correlation coefficient, 0.60-0.98). The standard error of the measurements as a percentage of the grand mean ranged from 0.004 to 19.94. CONCLUSIONS: The functional clinical test battery investigated in this study proved to be a reliable tool in the assessment of healthy subjects. The evaluation of postural control, proprioception, and muscle activity (coordination, stabilization, maximal voluntary isometric contraction, endurance, and flexion-relaxation) showed good to excellent repeatability and reproducibility. Further analysis of the reliability of these variables in a clinical setting, particularly in patients with low back pain, seems appropriate. Copyright © 2006 by Lippincott Williams & Wilkins.

This study hypothesizes that there is good correlation between the diagnostic impression of an unblinded electromyographer, using clinical and electromyographic information, and an independent electromyographer, who uses the needle examination only to assess for lumbar radiculopathy. This is a prospective, single-blinded, observational pilot study. The needle examination was electronically recorded, reproduced, and shown to a second examiner, blinded to all clinical data. Diagnostic impressions from both examiners were recorded and evaluated for agreement. Six recorded cases were reviewed by 66 blinded examiners. Overall diagnostic agreement was 46.9% (60.5% faculty level, 28.5% resident level). Logistic regression shows a strong association between training level and agreement on diagnostic impression (odds ratio, 1.9; 95% confidence interval, 1.12-3.22; P = 0.019). This study shows that there is fair interrater reliability between faculty-level examiners and poor reliability among resident-level examiners when the needle examination is used to evaluate patients with lumbar radiculopathy. © 2006 Wiley Periodicals, Inc.

Previous studies have shown that LBP diminishes the normal velocity-induced transverse counter-rotation between thorax and pelvis, and that it globally affects mean erector spinae (ES) activity. The exact nature and causation of these effects, however, are not well understood. The aim of the present study was to examine in detail the effect of walking velocity on global trunk coordination and ES activity as well as their variability to gain further insights into the effects of non-specific LBP on gait. The study included 19 individuals with non-specific LBP and 14 healthy controls. Gait kinematics and ES activity were recorded during treadmill walking at (1) a self-selected (comfortable) velocity, and (2) sequentially increased velocities from 1.4 up to maximally 7.0 km/h. Pain intensity, fear of movement and disability were measured before the experiment. The angular movements of thorax, lumbar and pelvis were recorded in three dimensions. ES activity was recorded with pairs of surface electrodes. Trunk-pelvis coordination and mean amplitude of ES activity were analyzed. In addition, invariant and variant properties of trunk kinematics and ES activity were studied using principal component analysis (PCA). Comfortable walking velocity was significantly lower in the LBP participants. In the transverse plane, the normal velocity-induced change in pelvis-thorax coordination from more in-phase to more antiphase was diminished in the LBP participants, while lumbar and pelvis rotations were more in-phase compared to the control group. In the frontal plane, intersegmental timing was more variable in the LBP than in the control participants, with additional irregular movements of the thorax. Rotational amplitudes were not significantly different between the LBP and control participants. In the LBP participants, the pattern of ES activity was affected in terms of increased (residual) variability, timing deficits, amplitude modifications and frequency changes. The gait of the LBP participants was characterized by a more rigid and less variable kinematic coordination in the transverse plane, and a less tight and more variable coordination in the frontal plane, accompanied by poorly coordinated activity of the lumbar ES. Pain intensity, fear of movement and disability were all unrelated to the observed changes in coordination, suggesting that the observed changes in trunk coordination and ES activity were a direct consequence of LBP per se. Clinically, the results imply that conservative therapy should consider gait training as well as exercises aimed at improving both intersegmental and muscle coordination. © Springer-Verlag 2005.

The aetiology of stuttering is, however, unknown and therefore it is not possible to treat it causally. In a pilot study carried out in six centres in the Czech Republic in accordance with a unified protocol for a period of 6 months, 42 patients were included. They were divided into two groups: A (school children and juveniles with a plan of 30 subjects) and B (adults aged 18-25, resistant to other treatment with a plan of 10 subjects). For six months, the patients receivesd a bronchodilatation substance, formoterol, exerting its influence via beta2 receptors. It was administered once daily in the morning in a dose of 12 mug. During 6 months, the evaluation of effectiveness on the basis of primary and secondary parameters was realised in each patient. The prime parameter, "extent of stuttering", was evaluated according to the ordinary scale (McGill Pain Questionnaire). The extent of stuttering was evaluated by an examining physician during the visits in centres and by the patients themselves (in case of the youngest with the assistance of a parent) on daily basis, recorded in the patient's diary. Initial EEG and EMG examinations were realised, biochemical tests performed at the beginning and at the end of the testing period. Spirometric values measured with the help of impulsed oscillometry, heart frequency variability, and tape records of speech fluency were recorded four times throughout the testing period. A non-parametric pair test (Wilcoxon signed rank test) was used for the comparison of average marks in the whole set of patients.

Design: Electromyographic recordings of single motor unit action potentials were made from the vastus medialis obliquus (VMO) and multiunit recordings from vastus lateralis during isometric contractions at 30degree of knee flexion in closed and open chain conditions. Setting: Laboratory. Participants: Five volunteers with no history of knee pain (age, 30+/-3.32y). Interventions: Not applicable. Main Outcome Measure: The degree of synchronization between motor unit firing was evaluated by identifying peaks in the electromyographic averages of the vastus lateralis, triggered from motor unit action potentials in the VMO, and the proportion of power in the power spectral density of the triggered average at the firing frequency of the reference motor unit. The proportion of cases in which there was significant power and peaks in the triggered averages was calculated. Results: The proportion of trials with peaks in the triggered averages of the vastus lateralis electromyographic activity was greater than 61.5% in all tasks, and there was a significantly greater proportion of cases where power in the spectrum was greater than 7.5% (P=.01) for the closed chain condition. Conclusions: There was a high proportion of synchronized motor units between the 2 muscles during isometric contractions, with evidence for greater common drive between the VMO and vastus lateralis in closed chain tasks. This has implications for rehabilitation because it suggests that closed chain tasks may generate better coordination between the vasti muscles. © 2005 by American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.

A cross-sectional study was performed, with prospective gathering of data, following a predetermined protocol. We included all patients older than 12 years who were referred for nerve conduction studies and electromyography of at least one of the upper limbs between August 2001 and January 2003. The patients answered a clinicoepidemiologic questionnaire and painted the areas in which they felt pain and those in which they felt paresthesia, and were also examined to test for classical signs CTS. A neurophysiological diagnosis of CTS was reached in 1549 upper limbs (39%). Approximately 6% of the upper limbs with N-CTS and 16% of those without median nerve lesion do not have any hand or wrist symptoms (P<0.001). Paresthesia, pain, hand weakness and cramps were the symptoms statistically associated to N-CTS, with paresthesia being the one with the greatest power of association. This is usually felt in median innervation's territory, and is frequently extended to the whole hand, but without association with N-CTS when felt in proximal region. One concludes that the most characteristic manifestation of carpal tunnel syndrome (CTS) is paresthesia. Pain also occurs very frequently but it is less specific, and weakness, meanwhile, seems to have a low frequency. We believe that the variability in the clinical presentation of CTS is largely due to the presence of associated diseases and our results provide information which could help to better define the clinical criteria used in the diagnosis of this syndrome. © 2004 International Federation of Clinical Neurophysiology.

Identification of abnormalities occurring in muscle activation patterns for injured athletes is relevant when prescribing rehabilitative exercises. Methods and Measures: Twelve throwers with shoulder pain were compared to a matched group of 11 asymptomatic throwers. Participants were matched for age, height, body mass, and habitual activity. Fine-wire EMG electrodes were inserted into the subscapularis, supraspinatus, and infraspinatus. EMG activity was measured during a reaction time task of rapid shoulder external rotation in a seated position. The timing of onset of EMG activity was analyzed in relation to visualization of a light (reaction time) and to the onset of infraspinatus activity (relative latency), Results: In the group with shoulder pain, the onset of subscapularis activity was found to be significantly delayed (reaction time, P = .0018; relative latency, P = .0005) from the onset of infraspinatus activity when compared to the control group. Conclusions: The presence of shoulder pain in these athletes was associated with a difference in the onset of subscapularis EMG activity during a rapid shoulder external rotation movement. This was an initial step in the understanding of the joint protection mechanisms of the glenohumeral joint and the problems that occur in throwers. This information may assist in providing future guidelines for more effective rehabilitation and prevention strategies for this condition.

Four patients with a PS total knee prosthesis and three patients with a MB total knee prosthesis were selected based on pain score, knee function, range of motion and joint stability. Clinical scores and functional scores were comparable between the two groups pre-operatively and at the 1-year follow-up. Visual analysis of the EMG activity of the main flexor and extensor muscles showed that the activity of both extensor and flexor muscles of the MB group was on average higher compared to the PS group. When the maximum activities of the muscles were compared, the patients in the MB group showed a significant higher maximum peak activity (p<0.05) of the Vastus Medialis (VM), Vastus Lateralis (VL) and Semitendinosus (ST) during step-up than the patients in the PS group. Also the instance of activation of the Vastus Medialis and the Vastus Lateralis was significant earlier in the MB group compared to the PS group. Since the differences between the PS and the MB group did not only show an increase of muscle activity but also an earlier activation of the flexor muscles, this may express compensation by coordination. Rehabilitation programs for RA patients should include besides muscle strength training, elements of muscle-coordination training. © 2004 Elsevier B.V. All rights reserved.

Spine loadings during a variety of lifting exertions were compared with individual torso kinematic abilities. Relationships were evaluated between these measures. Objective. To determine if trunk kinematic status (functional impairment) is indicative of spine loading increases in patients with low back pain (LBP) compared to asymptomatic individuals. Summary of Background Data. Recurrent LBP is a common and costly problem that may be related to increased spine loads in those individuals with LBP. Previous studies suggest that patients with LBP had greater loading than their asymptomatic counterparts when performing work. However, we know little about how to identify when a patient with LBP can resume lifting tasks without having exaggerated spine loading. Methods. Sixty-two patients with LBP and 61 who were asymptomatic were evaluated for signs of kinematic compromise (i.e., inability to generate normal trunk kinematic patterns) during a prelift test. All subjects were then asked to perform a variety of lifting exertions that varied in lift origin (region), lift asymmetry position, and weight lifted. An electromyography- assisted model was used to evaluate spine loading in each subject during the lifting exertions. Statistical models were used to assess the relationship between kinematic compromise and spine loading. Results. Patients with LBP had greater spine loading as well as greater kinematic compromise. The degree of kinematic compromise was related to the degree of spine loading increases in those individuals with LBP. A statistical model was developed that was able to describe 87% of the variability in compression, 61% in anteroposterior shear, and 65% in lateral shear. Conclusions. Those patients with greater kinematic compromise used higher levels of antagonistic muscle coactivation that not only reduced trunk motion but also resulted in increases in spine loading. Given the degree of kinematic compromise and the lifting task conditions, a method has been devised to predict the increase in spine loading above and beyond that of an asymptomatic individual when performing typical materials handling tasks. ©2005, Lippincott Williams & Wilkins, Inc.

It is hypothesized that injury or degeneration of osteoligamentous spinal structures would require compensation by trunk musculature and alterations in motor control to maintain spine stability. While, biomechanical modeling has supported this hypothesis, studies of muscle recruitment patterns in chronic low back pain patients both with and without significant osteoligamentous damage have been limited. This study utilized a non-randomized case-control design to investigate trunk muscle recruitment patterns around the neutral spine position between subgroups of patients with chronic mechanical low back pain and asymptomatic controls. Methods. Twenty subjects with chronic low back pain attributed to clinical lumbar instability were matched to 20 asymptomatic controls. In addition 12 patients with non-specific chronic low back pain were studied. Surface EMG from five trunk muscles was analyzed to determine activation levels and patterns of recruitment during a standing reach under two different loading conditions. Findings. The chronic low back pain group with symptoms attributed to clinical instability demonstrated significantly higher activation levels of the external oblique and rectus abdominus muscles and lower abdominal synergist ratios than the control group. No significant differences were found between patient subgroups. Interpretation. While these data demonstrate altered muscle recruitment patterns in patients with chronic low back pain, the changes are not consistent with Panjabi's theory suggesting that these alterations are driven by passive subsystem damage. However, the higher activation of global abdominal musculature and altered synergist patterns may represent a motor control pattern that has consequences for continued dysfunction and chronic pain. © 2005 Elsevier Ltd.

Often radiological diagnosis fails to give evidence of the pathogenesis of low back pain. Although psychophysiological characteristics have an influence, it seems that insufficient muscular spinal stabilization may play the major role in the development of low back pain. Assessment of trunk muscle stabilization activity during everyday activities is rare. Therefore, in this study healthy persons were investigated during walking on a treadmill at a speed of 4 km/h. Women (n = 16) with no history of back pain were investigated before and after a static loading situation of the spine, i.e. while wearing a waistcoat. After this loading situation four women developed pain (pain subjects). Surface EMG (SEMG) was taken from five trunk muscles of both sides. Grand averaged amplitude curves over stride, amplitude normalized curves and variation between all included strides were calculated for all muscles and subjects, respectively. The normal range of all calculated parameters was defined within the span between the 5th and the 95th percentiles of all pain free subjects. Data were evaluated according to deviations from the normal range. Already before the load situation, pain subjects showed considerable deviations from the normal range, mainly of their abdominal muscles. There was no relationship between magnitude of deviation and pain intensity, but perceived exertion was highest in those subjects who showed the most symptoms in terms of number of muscles being identified as considerably deviating from the normal range. No specific "dysfunction pattern" could be identified, which argues for highly individual mechanisms instead of a single target muscle. The results suggest cumulative effects of different disturbance levels resulting in acute back pain. Since deviations could be identified already before the pain occurred, disturbed muscle function seems to be a risk factor for developing back pain. Further investigations aimed at clear identification of and, as a second step, correction of muscle function are necessary. © 2005 Elsevier Ireland Ltd. All rights reserved.

It is reported that the electromyogram is an indicator of patient arousal during pain stimulation if anesthesia is inadequate. This may not be true during recovery from succinylcholine induced paralysis. We evaluated State entropy of the electroencephalogram (EEG, 0.8-32 Hz) and Response entropy, a combined measure of the electromyogram (EMG) and EEG (0.8-47 Hz), during recovery from paralysis with succinylcholine. Methods. Twenty patients were randomized to receive either 0.8% (n=10) or 1.4% isoflurane (n = 10), with 2 mg/kg succinylcholine administered for paralysis in all patients. State entropy and Response entropy were evaluated using a Datex-Ohmeda Entropy module. Frontal EMG was measured separately by an EEG module. State entropy, Response entropy, and EMG were measured in awake p atients, during isoflurane anesthesia and paralysis, and after 100% recovery to train of four stimulation. Results. Response entropy and State entropy decreased from awake levels in a dose related manner during 0.8% or 1.4% isoflurane and succinylcholine. Recovery from succinylcholine significantly increased Response entropy and EMG in 5 of 10 patients with 0.8% isoflurane and 8 of 10 with 1.4% isoflurane without a change in State entropy. Conclusion. Although RE and EMG increased during recovery from paralysis with succinylcholine, SE, an indicator of EEG, was not stimulated. EMG activity may not be an indicator of patient arousal after succinylcholine treatment. © Springer Science + Business Media, Inc. 2005.

The Datex-Ohmeda Entropy Module calculates state entropy (SE) of the electroencephalogram (EEG; 0.8-32 Hz) and response entropy (RE) of EEG and FEMG (0.8-47 Hz). We determined whether RE increases above SE (RE - SE), an indication of FEMG, increase during painful stimuli and if this is related to paralysis or level of anesthesia. With the unanesthetized baseline measurement, SE was 89 +/- 2 and RE was 98 +/- 2. During paralysis and anesthesia with either 0.8% (n = 10) or 1.4% (n = 10) isoflurane, SE decreased to 63 +/- 7 and 34 +/- 14, respectively, and the RE - SE difference decreased 90%. Before recovery from paralysis, arterial catheter or head pin placement increased RE - SE above unanesthetized levels in eight patients (five treated with 0.8% and three with 1.4% isoflurane), consistent with an increase in FEMG. The elevated RE - SE difference was related to a significant increase in SE, blood pressure, and heart rate. After recovery from paralysis, tetanic stimulation of the ulnar nerve increased the RE - SE difference above unanesthetized levels in 8 of 20 patients (6 treated with 0.8% and 2 with 1.4% isoflurane). In these patients, SE increased significantly. The remaining 12 patients did not show an increase in RE - SE during tetanic stimulation and SE did not increase. We conclude that increased RE during painful stimulation was not dependent on recovery from paralysis but was seen more often in patients anesthetized with 0.8% compared with 1.4% isoflurane. This suggests that RE reflects FEMG and may be useful to identify inadequate anesthesia and patient arousal during painful stimuli. Copyright © 2005 by Lippincott Williams & Wilkins.

The system was designed around the AMLAB analog modules and software objects called ICAMs. Each channel consisted of a time and frequency domain block, a torque and angle measurement block, an experiment number counter block and a data storage and retrieval block. The captured data in each channel was used to display and quantify: raw EMG, rectified EMG, smoothed rectified EMG, root-mean-squared EMG, fast Fourier transformed (FFT) EMG, and normalized power spectrum density (NPSD) of EMG. Torque and angle signals representing elbow extension measured by a KIN-COM dynamometer during neural tension testing, as well as signals from an electronic pain threshold marker were interfaced to AMLAB and presented in one integrated display. Although this system has been designed to specifically study the patterns and nature of evoked motor responses during clinical investigation of carpal tunnel syndrome (CTS) patients, it could equally well be modified to allow acquisition, processing and analysis of EMG signals in other studies and applications. In this paper, we present for the first time the steps involved in the design, implementation and testing of an integrated AMLAB-based system to study and analyse the mechanically evoked electromyographic, torque and ROM signals and correlate various levels of pain to these signals. We also present samples of resistive torque ROM, and raw and processed EMG recordings during passive elbow extension.

It was investigated whether the changes were an effect of employment duration and of development of neck-shoulder complaints. Methods: Twelve newly employed female filleting employees without any sign of neck-shoulder tenderness/pain at the time of employment of 0 months took part in two laboratory recording sessions planned within 1 month of employment and after 6 months of employment at the plant. After 6 months, six workers out of 12 had developed pain and/ or tenderness in the neck-shoulder region. The recording sessions evaluated sensory-motor aspects by measuring pressure pain threshold, work-task timing, cutting forces, surface electromyographic activity of four shoulder muscles, displacement of the centre of pressure, and 3D movements of the arm and trunk during simulation of low load, repetitive filleting. Results: Effects due to the duration of employment were observed in both groups, i.e. decreased sensibility to pressure, decrease in the duration of the work cycle, increased arm starting position with respect to the upright position, and decreased range of motion of the arm and trunk (P<0.05) after 6 months. Among the workers with neck-shoulder complaints, increased sensibility to pressure, lower force level, higher electromyographic activity, decreased amplitude of arm movement, and increased trunk posture and movement amplitude (P<0.05) were observed, compared with workers without complaints. Conclusions: Differences in terms of sensory manifestations and motor control strategy were seen after 6 months of employment with or without neck-shoulder complaints. In general, changes in sensory manifestations and motor control strategy after 6 months work were most likely of importance, as they underlined a learning process as employment duration increased. Moreover, the present sensory-motor changes observed among workers with neck-shoulder complaints highlighted the potential physical risk factors associated with low load, repetitive work.

A playing technique with more relaxed muscles and a greater variation in the muscle activity pattern, i.e., with shorter sequences at a varied number of amplitude levels as reflected by electromyography (EMG), might prevent pain. This study used EMG to study variations in the trapezius muscle activity pattern in 12 string musicians performing a piece of music at two playing sessions separated by a ten-week interval. Nine of the string musicians played violin, two viola and one cello. Exposure variation analysis and principal component analysis were used for analysis of the EMG. The trapezius muscle activity pattern was similar in the first and second playing sessions showing that each musician repeated his/her own muscular activity pattern. However, there was considerable variability in the muscle activity pattern between cello, violin and viola players and between individual violin players. Thus, this EMG method has the potential to identify variations and reproducibility of trapezius muscle activity in string musicians. This method may be used to analyse individual differences when performing a musical work task and to evaluate intervention studies. Relevance to industry: Intervention studies on muscle activity pattern which try to change the work technique need to be evaluated. © 2003 Elsevier B.V. All rights reserved.

To examine the effects of experimentally induced pain and fear of pain on trunk coordination and erector spinae EMG activity during gait. Design. In 12 healthy subjects, hypertonic saline (acute pain) and isotonic saline (fear of pain) were injected into erector spinae muscle, and unpredictable electric shocks (fear of impending pain) were presented during treadmill walking at different velocities, while trunk kinematics and EMG were recorded. Background. Chronic low back pain patients often have disturbed trunk coordination and enhanced erector spinae EMG while walking, which may either be due to the pain itself or to fear of pain, as is suggested by studies on both low back pain patients and healthy subjects. Methods. The effects of the aforementioned pain-related manipulations on trunk coordination and EMG were examined. Results. Trunk kinematics was not affected by the manipulations. Induced pain led to an increase in EMG variability and induced fear of pain to a decrease in mean EMG amplitude during double stance. Conclusions. Induced pain and fear of pain have subtle effects on erector spinae EMG activity during walking while leaving the global pattern of EMG activity and trunk kinematics unaffected. This suggests that the altered gait observed in low back pain patients is probably a complex evolved consequence of a lasting pain, rather than a simple immediate effect.Relevance Variability of EMG data and kinematics may explain pain-dependent alterations of motor control, which in turn might contribute to a further understanding of the development of movement impairments in low back pain. © 2003 Elsevier Ltd.

This study's aim was to investigate the effect of "readiness training" on the response to sudden back loading among untrained healthy individuals. The study included 19 participants and 19 matched controls. All were employees at the National Institute of Occupational Health. The participants received ten 45-min training sessions during a 4-week period. The training focused on reactions to a variety of expected and unexpected sudden trunk loadings, including balance and coordination exercises. Before and after the training, all subjects were tested for reaction to sudden trunk loading (SL). This entailed applying a horizontal force of 58 N to the subject's upper back. Elapsed time - measured between SL and stopping - decreased significantly in the training group (from 337 to 311 ms) compared with the control group. The improved stopping time was associated with a changed EMG signal, characterized by an increase in the early parts of the response (up to 225 ms) and a subsequent decrease. EMG onset latency was unaffected by training. This study is apparently one of the first to demonstrate that the response to sudden trunk loading can be improved in healthy subjects without an increase in pre-activation and associated trunk stiffness.

Material and methods: In 26 male volunteers, electrical stimulation at the distal cutaneous receptive field of the sural nerve elicited pain and a nociceptive withdrawal reflex. Intensity of pain was rated on a numeric rating scale. Electromyographic reflex responses were measured from biceps femoris muscle. Cardiac autonomic function was estimated by heart rate variability measures and was expressed in the time domain as mean of RR-intervals for normal heart beats (mean-RR) and standard deviation of all normal RR-intervals (SD-NN) and, in the frequency domain, where pure vagal activity was assessed by high frequency power (0.15-0.4 Hz). Low frequency power (0.04-0.15 Hz) reflects both parasympathetic and sympathetic control. Effect parameters were recorded before and during random distraction and attention. Distraction from sural nerve stimulation was induced by a mental arithmetic test, paced auditory serial addition task (PASAT), while attention was induced by concentrating on painful foot stimulation. Results: Paced auditory serial addition task decreased mean-RR and SD-NN, frequency domain parameters, as well as pain (P < 0.001). In contrast, PASAT did not change the spinal withdrawal reflex. Attention did not affect any effect parameter. Conclusion: Distraction by PASAT altered autonomic activity and inhibited pain but failed to affect withdrawal reflex responses, while attention had no effect on either parameter. Psychological distraction and attention may have different effects on noxious evoked pain perception and autonomic activity. Pain relief during PASAT probably involves supraspinal mechanisms.

The Medline and PsychInfo databases were searched to obtain all papers published from 1975 to 2003 that included the terms "biofeedback" and either "constipation," "pelvic floor dyssynergia," "fecal incontinence," or "anorectal pain." Adult and pediatric papers in any language were screened. Prospective studies with five or more participants and a description of the treatment protocol and outcome were selected for review. Seventy-four studies qualified for review: 33 trials on fecal incontinence (FI), 38 on pelvic floor dyssynergia (PFD) or functional constipation, and 3 on anorectal pain. Only 20% of studies were controlled outcome trials. Treatment protocols, etiological subgroups studied and outcome measures varied greatly. The overall average probability of successful treatment outcome for patients treated with biofeedback was 67.2% for functional FI and 62.4% for constipation. There were insufficient data to warrant such calculation for anorectal pain. According to standard efficacy rating criteria, biofeedback treatment is efficacious for functional constipation or PFD in children and probably efficacious in adults; probably efficacious for functional FI; and possibly efficacious for anorectal pain. Utilizing data from all applicable studies, we found that success rate per subject is significantly higher for biofeedback treatment than for standard medical care for PFD/functional constipation, and FI (p < .001 for both). Biofeedback treatment may therefore be viewed as a valuable adjunct to medical management of functional PFD/constipation and incontinence. A number of recommendations for future investigations are made based on the review.

Seventy-five volunteer subjects participated in this study and were equally divided between Group 1, asymptomatic control subjects, Group 2, subjects with insidious onset neck pain and Group 3, subjects with neck pain following a whiplash injury. The cranio-cervical flexion test was performed in five progressive stages of increasing cranio-cervical flexion range. Subjects' performance was guided by feedback from a pressure sensor inserted behind the neck which monitored the slight flattening of the cervical lordosis which occurs with the contraction of longus colli. Myoelectric signals (EMG) were detected from the muscles during performance of the test. The results indicated that both the insidious onset neck pain and whiplash groups had higher measures of EMG signal amplitude (normalized root mean square) in the sternocleidomastoid during each stage of the test compared to the control subjects (all P < 0.05) and had significantly greater shortfalls from the pressure targets in the test stages (P < 0.05). No significant differences were evident between the neck pain groups in either parameter indicating that this physical impairment in the neck flexor synergy is common to neck pain of both whiplash and insidious origin. ©2003 Elsevier Ltd.

Some authors recognise persistent pain after back surgery as a syndrome in its own right, without regard to the mechanism or cause of pain. FBSS has important medical, social, legal and economic implications on the whole society as well as on every involved patient and his (her) environment. We should keep in mind the complexity of this clinical problem, the multidimensional nature of chronic pain (mechanistic and pathologic heterogeneity), psychological and social comorbidities, variation in pain experience of the patient population with FBSS. The general lack of studies with a high-quality design results in 1differences in outcome assessment and failed efforts to optimize patient selection to operation (reoperation), diagnostic and treatment criteria, and have resulted in a wide variation of reported outcomes. Recent work has focused on the necessity of refining the therapies for FBSS and identification of factors influencing therapeutic outcome and improving patient selection criteria. Failure of surgical treatment and errors in diagnostic procedures may depend on preoperative, perioperative, or postoperative factors. The causes of FBSS vary widely and include many factors. It is very difficult to treat complaints related to this syndrome due to a variability of pain generators. Selection of optimal treatment modalities is difficult because the cause of pain and origin of this syndrome have not been precisely defined in a lot of individual cases. At present, it appears a large proportion of patients have identifiable and potentially treatable lesions. That is why FBSS is not a nihilistic endpoint yet and almost all FBSS are potentialy curable.

The ensuing paper reviewed this literature and drew several conclusions. Injured patients and healthy volunteers do produce less force and more variable force while performing submaximal contractions than maximal contractions. However, submaximal efforts during strength testing can be reproduced and the use of force variability is not adequate to distinguish sincerity of effort. Visual examination of the shape of force output curves is also not adequate for distinguishing sincerity of effort. Furthermore, much of the research using strength ratios, difference scores, and an assortment of different parameters derived during strength testing has not established reliable and clinically useful methods of differentiating effort levels. Methods examining motion variability, radial/ulnar force output ratios, difference scores of eccentric-concentric ratios, and electromyography offer some promise, but numerous critical issues need to addressed. The use of the coefficient of variation, for example, is statistically untenable given the number of trials appropriate for clinical samples. Several studies have inadequate sample size to number of variable ratios. Many studies have questionable or at least unknown generalizability to patient samples and actual functional capacity. It is critical that other explanatory variables such as fear of injury, pain, medications, work satisfaction, and other motivational factors be considered. It is our opinion that there is not sufficient empirical evidence to support the clinical application of muscle testing to determine sincerity of effort.

The potentially compressive sites are numerous and should be known to avoid therapeutic failure. Pathophysiology is yet better understood but is still debated. Clinical and radiological examination and the EMG allow a better aetiologic definition.The aetiology of the ulnar nerve suffering (entrapment or instability of the nerve), the medical history of the patient, the length and the severity of the complaint explain the great variability in the results observed and the large choice of possible therapies. Apart from the medical treatment, we list the different surgical techniques: in situ neurolysis, medial epicondylectomy, partial medial epicondylectomy, anterior submuscular or intramuscular or subcutaneous transposition. These interventions have near-identical results, leading us to choose for its simplicity in realisation and after surgery, the in situ neurolysis when the nerve is stable. In case of subluxation of the ulnar nerve, we advise partial medial epicondylectomy, which conserves the vascularisation of the nerve, and limits it's stretching and compression. Partial medial epicondylectomy has, as the total epicondylectomy, good results without the disadvantages. In the case of real instability and in certain cases of severe paralysis, the anterior transpositions, which are more difficult to do and have more complex postoperative care, remain justified. © 2004 Publie par Elsevier SAS.

The present systematic review focuses on terminology, clinical presentation, and prevalence. Numerous terms are used, as if they indicated one and the same entity. We propose "pregnancy-related pelvic girdle pain (PPP)", and "pregnancy-related low back pain (PLBP)", present evidence that the two add up to "lumbopelvic pain", and show that they are distinct entities (although underlying mechanisms may be similar). Average pain intensity during pregnancy is 50 mm on a visual analogue scale; postpartum, pain is less. During pregnancy, serious pain occurs in about 25%, and severe disability in about 8% of patients. After pregnancy, problems are serious in about 7%. The mechanisms behind disabilities remain unclear, and constitute an important research priority. Changes in muscle activity, unusual perceptions of the leg when moving it, and altered motor coordination were observed but remain poorly understood. Published prevalence for PPP and/or PLBP varies widely. Quantitative analysis was used to explain the differences. Overall, about 45% of all pregnant women and 25% of all women postpartum suffer from PPP and/or PLBP. These values decrease by about 20% if one excludes mild complaints. Strenuous work, previous low back pain, and previous PPP and/or PLBP are risk factors, and the inclusion/exclusion of high-risk subgroups influences prevalence. Of all patients, about one-half have PPP, one-third PLBP, and one-sixth both conditions combined. Overall, the literature reveals that PPP deserves serious attention from the clinical and research communities, at all times and in all countries. © Springer-Verlag 2004.

The detection of anticipatory postural adjustment via trunk muscle onsets from electromyographic (EMG) signals can be problematic due to baseline noise or electro-cardiac (ECG) artefact. Shewhart protocols or whole signal analyses may show different degrees of sensitivity under different conditions. Muscle activity onsets were determined from surface EMG of seven muscles for five trials before and after fatigue were examined in four subjects (n=280). The objective of this study was to examine two detection methods (Shewhart and integrated protocol (IP)) in determining the onsets of trunk muscles. The variability of the baseline amplitude and the impact of added Gaussian noise on the detected onsets were used to test for robustness. The results of this study demonstrate that before and after fatigue there is a large degree of baseline variance in the trunk muscles (coefficients of variation between 40-65%) between trials. This could be normal response to body sway. The IP method was less susceptible to false onsets (detecting onsets in the baseline window) 3 vs. 51%. The findings suggest the IP method is robust with large variance in the baseline if the signal to noise ratio is greater than six. In spite of the robustness of the algorithm, the findings would suggest that statistical assessments should be used to target trials for selective visual inspection for subtle trunk muscle onsets.

However, one important measure of the muscular coordination in the scapular muscles, the timing of the temporal recruitment pattern, is undetermined. Purpose: To evaluate the timing of trapezius muscle activity in response to an unexpected arm movement in athletes with impingement and in normal control subjects. Study Design: Prospective cohort study. Methods: Muscle latency times were measured in all three parts of the trapezius muscle and in the middle deltoid muscle of 39 "overhand athletes" with shoulder impingement and compared with that of 30 overhand athletes with no impingement during a sudden downward falling movement of the arm. Results: There were significant differences in the relative muscle latency times between the impingement and the control group subjects. Those with impingement showed a delay in muscle activation of the middle and lower trapezius muscle. Conclusion: The results of this study indicate that overhand athletes with impingement symptoms show abnormal muscle recruitment timing in the trapezius muscle. The findings support the theory that impingement of the shoulder may be related to delayed onset of contraction in the middle and lower parts of the trapezius muscle. © 2003 American Orthopaedic Society for Sports Medicine.

Methods: Twenty healthy subjects underwent assessment of the effect of electrical finger-tip stimulation with different intensities on voluntarily contracting hand muscles. The rectified and averaged electromyogram (EMG) was recorded with surface electrodes placed over abductor pollicis brevis (APB), abductor digiti minimi (ADM), and first dorsal interosseous (FDI) muscles following recurrent digit II and digit V stimulation. Results: Finger-tip stimulation resulted in a series of inhibitory and excitatory EMG responses in all 3 hand muscles. Stimulus intensity exerted a significant influence on various CSP parameters (probability, onset and end latency, duration, index of suppression). CSPs were most pronounced in APB following digit II and, somewhat less, following digit V stimulation. FDI and ADM differed in CSP onset latency following digit II stimulation, and in the overall amount of suppression following digit V stimulation, despite being supplied by the same nerve and the same myotome. Excitatory long-loop reflexes seemed to be suppressed by increasing stimulus intensities, yet they interfered with CSPs, even when using noxious stimulation, in FDI following digit II stimulation, and in both ADM and FDI following digit V stimulation. Conclusions: The findings are consistent with the presence of an inhibitory neural circuitry within the human spinal cord which can rapidly restrain distinct muscle synergies. Neurophysiology indicates a more functional - task-related - organization of protective reflexes in the human upper extremity, rather than a merely metameric - anatomically based - order of activation of this neuronal circuitry. © 2003 International Federation of Clinical Neurophysiology.

They involve the somatic as well as the autonomic nerves. Nearly 50% of the diabetic patients get a polyneuropathy during their illness. The clinical pattern is variable. The most frequent types are the symmetric-sensory forms, followed by the symmetric-motor and the asymmetric forms. Special subtypes are the diabetic ophthalmoplegia, the diabetic radiculopathy and the diabetic amyotrophy. The autonomic neuropathy affects almost all organs. The most important disorders are cardiovascular, gastrointestinal and urogenital dysfunctions as well as trophic disturbances. The therapeutic basis is the glycemic control. In the case of pain a symptomatic treatment is possible.

Design: Subjects performed fatiguing right and left isometric axial rotation of the trunk at 80% of maximum voluntary contraction while standing upright. Setting: A rehabilitation center. Participants: Twenty-three men with no history of back pain. Interventions: Not applicable. Main Outcome Measures: Surface electromyographic signals were recorded from 6 trunk muscles bilaterally. The primary torque in the transverse plane and the coupling torques in sagittal and coronal planes were also measured. Results: During the fatiguing axial rotation contraction, coupling torques of both sagittal and coronal planes were slightly decreased and no difference was found between directions of axial rotation. Decreasing median frequency and an increase in electromyographic amplitude were also found in trunk muscles with different degrees of changes in individual muscles. There were significant differences (P<.05) between right and left axial rotation exertions in median frequency slope of external oblique, internal oblique, latissimus dorsi, and iliocostalis lumborum muscles, but no such difference was found in median frequency slope of rectus abdominis and multifidus muscles. This could be attributed to different functional roles among the muscles. Similar differences (P<.05) between right and left axial rotation in median frequency slope were also detected in the electromyographic amplitude slope of the trunk muscles. Coefficient of variation of the torque output and electromyographic activation in most of the trunk muscles increased during the fatigue process. Conclusion: The changing coupling torque, different fatigue rate, and activation changes of trunk muscles, as well as the increase in variability during fatiguing axial rotation exertion, could affect the internal loading and stability of the spine; this needs to be further quantified in future studies. © 2003 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.

Many studies have documented compromised muscle function in patients with CLBP. Although the mechanism associating muscle insufficiency to CLBP is not clearly understood, it is commonly held that the passive tissues of the spine are increasingly stressed with increasing functional muscle insuffiency. Functional instability of the spine plays a major role in the development of back pain. During the last few years, objective evaluation of the fatigue of back muscles by surface electromyography (EMG) with quantitative spectral techniques, evaluation of fibre type and size of the back muscles and quantifying of postural control of the lumbar spine during different tasks documented the failure of the spine in CLBP patients by a deficit of motor control more objectively. Besides this deficit, many patients show severe psychosocial problems and fear-avoidance beliefs. On this basis, treatment of CLBP with active rehabilitation, which includes educational, psychological, and social components along with the therapeutic exercises, has been increasingly advocated during recent years.

We thus studied phenotype variability and the diagnostic pootential of clinical and laboratory investigations in patients with RCD. We retrospectively evaluated clinical and laboratory investigations in 130 patients with RCD: 63 women and 67 men, aged 17-87 years, diagnosed between January 1992 and December 1999. mtDNA mutations were found in 20 patients; a respiratory chain defect but no mutation in 4; an abnormal lactate stress test but no mutation or biochemical defect in 66; and ragged-red fibres or reduced oxidative enzyme staining but no mutation, biochemical defect or abnormal lactate stress test in 40 patients. The most frequent initial manifestation of RCD were limb weakness, muscle pain and sensory disturbances. The most frequent clinical findings at diagnosis were muscle pain, fatiguability, limb weakness, reduced tendon reflexes and muscle wasting, irrespective of the diagnostic evidence. Mean age at onset, disease duration and time until diagnosis were 39, 14 and 13 years, respectively, without sex differences. The family history was positive in 29% of the patients. Hyperlipidaemia was found in 45%, hyper-CK-aemia in 42%, short stature in 33%, thyroid dysfunction in 17%, diabetes in 12%, and epilepsy in 8% of the patients. Laboratory investigations that prove useful to support the diagnosis of RCD are muscle biopsy, electromyography, lactate stress testing, echocardiography and mtDNA analysis. Systems most often involved in RCDs were the PNS, CNS, endocrine system and heart. The diagnosis of RCD requires awareness of the great phenotypic heterogeneity and an individualized, integral, multidisciplinary approach.

Design: Cross-sectional. Setting: University laboratory in Australia. Participants: Thirty-seven subjects with PFPS and 37 asymptomatic sex-matched controls. Interventions: Not applicable. Main Outcome Measures: Recordings of electromyographic activity of the VMO, vastus lateralis, tibialis anterior, and soleus were made by using surface electrodes. Subjects rose onto their toes (rise task) or rocked back on their heels (rock task) in a visual choice-reaction time task. Electromyographic onsets were determined by using a computer algorithm and were verified visually. Results: Our results confirm that, in asymptomatic subjects, contraction of the VMO and vastus lateralis occurs as part of the feed-forward postural response associated with ankle movements in standing, and the contraction of these separate heads of the quadriceps group occurs simultaneously. However, when subjects with PFPS perform identical tasks, the electromyographic onset of the vastus lateralis occurs before that of the VMO. Conclusion: These findings indicate a difference in motor control in subjects with PFPS. They also support the hypothesized relation between changes in the timing of activity of the vastii and PFPS and provide the theoretic rationale to support physiotherapy treatment commonly used in the management of PFPS. © 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.

This concept has only rarely been evaluated for prevention and rehabilitation in back pain. This fact should be considered regarding the still growing number of musculo-skeletal diseases. Therefore the influence of coordinative training in the three dimensional concept of Spacecurl has been investigated in a randomised controlled study regarding coordination, back pain and quality of life. Materials and Methods: A randomised controlled study included 104 nursing personnel of the Medical Faculty of the Martin-LutherUniversity Halle-Wittenberg (mean age: 35,1), without back pain at the start of study (evaluation point 1). 52 test persons took part in an active standardized coordination training program (36 training sessions of 30 minutes each, once to twice weekly). The control group contained 52 test persons without training. Body surface electromyography and posturography were used as instruments of clinical functional diagnostics. A specially devised questionnaire recording back pain and the WHOQOL-BREF (German version) for the evaluation of living quality was used. The investigation parameters were recorded at 4 intervals. Results: No significant difference was found between the active and passive group at evaluation point 1. Functional diagnostics (body surface electromyography; posturography) showed significant improvements in 69% and 74% in active group (p < 0.001; evaluation point 2). The result could be reproduced with high significance by surface electromyography. Back pain frequency decreased significantly in 34% of the active group (p = 0.016; evaluation point 2), also life quality showed a significant increase in 43% of these health care workers (p = 0.028; evaluation point 2). The untrained group showed no significant changes (evaluation point 2 and 3) in all investigation parameters. The regression analysis showed no direct relationship between the parameters coordination, back pain and quality of life to each other but they improved independently in the active group. Conclusion: The used coordination training in the Spacecurl led to significant improvements in the independent variables, coordination, back pain and quality of life.

Subjects: Ten healthy volunteers with no history of low back pain (six males). Main outcome measures: The surface EMG signal during 60-second isometric contractions of the paraspinal muscles at 40, 50 and 60% levels of maximal voluntary contractile force was captured and analysed. Each contraction level was assessed on two occasions, at least three days apart. The initial median frequency, the decline in median frequency slope and the increase in root mean square values were assessed for between-days reliability, using intraclass correlation coefficients (ICCs) and standard errors of measurements (SEM). Normalized median frequency and root mean square values were also assessed. Results: At 40% of maximal voluntary contraction, little or no EMG fatigue changes occurred in any of the observed parameters. At 50% maximal voluntary contraction the initial mean frequency and root mean square changes proved highly reliable, with ICCs ranging from 0.74 to 0.86 and 0.75 to 1.00 respectively. Normalizing the root mean square data reduced the reliability, but this was still acceptable with ICCs 0.70-0.83. The median frequency decline slope proved less reliable with ICCs 0.24-0.74 for raw and 0.26-0.77 for normalized data. At 60% maximal voluntary contraction the initial mean frequency proved as reliable as initial median frequency at 50% with ICCs 0.70-0.89. The raw and normalized root mean squares (ICCs 0.43-0.89 and 0.30-0.87 respectively) and raw and normalized median frequency (ICCs 0.27-0.51 and 0.24-0.53 respectively) changes were less reliable than at 50% MVC. Overall, the reliability is better at the L4/5 than at the L2/3 level. Conclusion: Outcome measures taken at 50% maximal voluntary contraction are the most reliable in functional testing the paraspinal muscles of healthy volunteers. With initial median frequency and root mean square values being more reliable parameters than median frequency decline. At the L4/5 level, however, all parameters were acceptably reliable at 50% of maximum effort. However the between-subject variability of the median frequency decline and root mean square incline slopes suggest that these parameters are not yet fully suitable for monitoring fatigue changes during prolonged isometric contraction.

In the present work, we describe an inhibitory reflex evoked in human masseter muscles by stimulation of non-nociceptive fibres travelling in the median and radial nerves (MED and RAD, respectively). Eighteen healthy volunteers participated in the study. Subjects were seated on a comfortable chair, with the complex head-mandible-neck-trunk and the limbs securely fixed to the chair. Attempts were made to minimize possible interferences due to the activation of afferents other than the stimulated ones. The subjects were instructed to contract masseter muscles at a submaximal level and to maintain a stable level of muscle contraction during all trials. EMG voluntary activity was recorded from both masseter muscles by means of coaxial needle electrodes before and after the electrical stimulation of MED and/or RAD at intensities below pain threshold. In all subjects, MED stimulation induced bilaterally a marked depression of masseter EMG activity, which occurred at a latency of 23.6+/-2.1 ms and lasted 27.8+/-6.6 ms. RAD stimulation also induced a marked reduction in masseter EMG activity, but this effect was clearly observed in 9 out of 18 subjects, and it showed latency (30.2+/-7.5 ms) and duration (44.9+/-5.4 ms) significantly longer in comparison with the MED-induced effect. All subjects exhibited the inhibitory period in masseter EMG following the simultaneous stimulation of both nerves; this one appeared at a latency not significantly different (25.3+/-5.9 ms) and lasted much more (37.4+/-8.2 ms) than EMG depression evoked by MED stimulation. The duration of masseter muscle inhibition, induced by MED and/or RAD stimulation, was inversely related to the level of EMG activity, while latency was not related to it. Significant increases in the inhibitory period duration were also observed by increasing stimulus intensity, within a subthreshold range for the activation of nociceptive fibres. In all cases, the inhibitory period was followed by a later excitatory rebound activity, whose latency and duration depended on the duration of the preceding EMG inhibition and on the background level of masseter activation. In conclusion, results evidenced that the activation of arm somatosensory fibres modulates masseter muscle activity in normal man. This might lead to a coordination between limb and masticatory muscle activity, which is required in several complex motor acts.

Therefore, intraoperative neurophysiological monitoring techniques have been developed to prevent neurological complications postoperatively. We performed a retrospective chart review of 63 patients who had undergone tethered cord release. We excluded adult patients, those lost to follow-up and patients with either a myelomeningocele and/or lipoma. This limited our study to 25 pediatric patients, aged 4 months to 12 years, who underwent tethered cord release for either a thickened filum terminale and/or a low-lying conus. For intraoperative monitoring, we utilized electrical stimulation of the filum terminale, lumbosacral nerve roots and electromyography recordings. Ventral nerve roots were identified and their electrical thresholds obtained. The mean was 0.32 V, the mode 0.1 V and the range 0.05-1.0 V. These values were compared to electrical thresholds obtained by stimulation of the filum terminale. The mean was 26.1 V, the mode 20.0 V and the range 8-100 V. In over 70% of patients, muscle activation via the filum required 100 times the voltage needed to activate a motor root. This motor root to filum threshold of 1:100 was useful in identifying the filum. Clinical outcome showed no significant worsening with respect to bowel and bladder control or pain and motor indices. Significant bowel and bladder improvement was seen in 4 out of 25 patients, motor improvement in 9 out of 25 patients and improvement of pain in 4 out of 25 patients. Three patients developed postoperative urinary tract infections, but no cerebrospinal fluid leaks or pseudomeningoceles were encountered. These results suggest that patients with a thickened filum or low-lying conus can safely undergo tethered cord release. Intraoperative neurophysiological monitoring provides a helpful adjunct to distinguish nerve roots from the filum. A ratio, rather than an absolute number, is beneficial in distinguishing motor roots from the filum and eliminates variability due to patients' individual differences in electrical thresholds.

In a group of healthy subjects (n=77) and patients with sub-acute (n=24) and chronic (51) low back pain, the normalised electromyographic (EMG) activity of the MF and the ICLT (as a percentage of maximal voluntary contraction) were analysed during coordination, stabilisation and strength exercises. The results showed that, in comparison with the healthy subjects, the chronic low back pain patients displayed significantly lower (P=0.013) EMG activity of the MF during the coordination exercises, indicating that, over the long term, back pain patients have a reduced capacity to voluntarily recruit the MF in order to obtain a neutral lordosis. In contrast, during the stabilisation exercises, no significant differences between patients and controls were found for the normalised EMG activity of the two muscles. These findings indicated that, during low-load exercises, no insufficiencies in back muscle recruitment were evident in either sub-acute or chronic back pain patients. During the strength exercises, the normalised activity of both back muscles was significantly lower in chronic low back pain patients (P=0.017 and 0.003 for the MF and ICLT, respectively) than in healthy controls. Pain, pain avoidance and deconditioning may have contributed to these lower levels of EMG activity during intensive back muscle contraction. The possible dysfunction of the MF during coordination exercises and the altered activity of both muscles during strength exercises may be of importance in symptom generation, recurrence or maintenance of low back pain.

Design: A prospective, comparative, repeated-measures design. Setting: Motion analysis research laboratory. Participants: Fourteen men with LBP (mean duration, 8y; mean age +/- standard deviation, 39+/-5y). Interventions: Subjects performed 3 exercises in random order while surface electromyograms were recorded from 5 muscle sites: lower and upper rectus abdominus, external oblique, erector spinae, and multifidus. The exercises were divided into 2 phases: a movement phase and a stabilization phase. The root-mean-square (RMS) electromyographic amplitude for each phase was calculated and normalized to the highest RMS amplitude from a series of 4 exercises, which attempted to elicit maximal voluntary isometric contractions (MVICs) for each muscle. A 2-factor, repeated-measures analysis of variance (ANOVA) tested the muscle by exercise interaction and the 2 main effects for each phase separately. Main Outcome Measures: Normalized RMS amplitude was the main dependent variable. The ensemble-average profiles for each muscle were calculated to examine the phasing of activation throughout the exercises. Results: The ANOVA revealed a statistically significant muscle-by-exercise interaction (P<.05) for both phases, which showed that the 3 exercises; recruited the 5 muscle sites using different patterns of relative amplitudes. The external oblique muscle site was activated to higher amplitudes than the other 4 muscle sites for all 3 exercises; the highest normalized RMS activity occurred at the external oblique during the pelvic tilt (32% MVIC). The phasic patterns among the 5 muscle sites were not consistent for the TST but were consistent among the 5 sites for the other 2 exercises. Conclusions: None of the exercises recruited the abdominal muscles to intensities deemed adequate for strengthening. The TST challenges the coordination of muscle activity during the leg-loading task (stabilization phase) as evidenced by changes in amplitudes over the total exercise time for the external oblique site, but not the other 4 sites. All 3 exercises could be used as initial exercises in a dynamic stability progression when low-recruitment amplitudes of specific muscles were the objective but not for strengthening. © 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.

Surface electromyographic signals were collected from 14 lower torso muscles while participants resisted high-magnitude static trunk moments applied in a variety of directions. Objectives. To obtain a description of muscle activations in response to large moment magnitudes and axial twisting, including levels of agonistic and antagonistic muscle cocontraction. To assess differences in lower torso muscle activation patterns associated with gender and trial repetition. Summary of Background Data. Back pain is associated with mechanical loads in the back. Biomechanical modeling of these loads is facilitated by knowledge of typical muscle activation patterns. Previous efforts in obtaining such data have often limited their scope to low-magnitude exertions or relatively simple scenarios. Methods. Eight male and eight female participants, matched by height and mass, performed static exertions in an apparatus that immobilized their lower body while the activation levels of seven bilateral torso muscles were measured using surface electromyography. Activation patterns were analyzed to assess differences resulting from a variety of factors. Results. No significant differences in activation patterns were found between genders or repetitions, but moment magnitude and direction elicited substantial differential responses. Good repeatability was found between trial repetitions, as indicated by intraclass correlation coefficients (<0.65). Significant synergistic muscle coactivation, large intersubject variability (mean coefficient of variation 82.2%), and consistent levels of antagonism ranging from 10% to 30% maximum voluntary exertions were observed. Conclusions. Individuals of different genders, but similar anthropometry, have comparable muscular reactions to complex torso loads, suggesting similar motor control strategies. Future spine models should consider that the variability in muscle recruitment patterns is larger between subjects than within subjects. High-magnitude exertions, especially those with moment loads in more than one plane, require most muscles to be active (<5%) and moderate levels of antagonism.

This study measured functional capacity and subjective pain in patients with chronic neck pain before and after manipulation of the cervical spine. Design. Outcomes study on 16 patients with chronic neck pain. Background. Muscle inhibition, i.e., the inability to fully activate a muscle, has been observed following joint pathologies and in low back pain conditions. Although chronic neck pain has been associated with changes in muscle recruitment and coordination in the shoulder and arms, the possibility of muscle inhibition has not been explored. Methods. Biceps activation during a maximal voluntary elbow flexor contraction was assessed using the interpolated twitch technique and electromyography. Cervical range of motion and pressure pain thresholds were measured using a goniometer and an algometer. Manipulation of the cervical spine was applied at the level of C5/6/7, and functional assessments were repeated. Results. Patients showed significant inhibition in their biceps muscles. Cervical range of motion was restricted laterally, and increased pressure pain sensitivity was evident. After cervical spine manipulation, a significant reduction in biceps inhibition and an increase in biceps force occurred. Cervical range of motion and pressure pain thresholds increased significantly. Conclusions. Significant dysfunction in biceps activation was evident in patients with chronic neck pain, indicating that this muscle group cannot be used to the full extent. Spinal manipulation decreased muscle inhibition and increased elbow flexor strength at least in the short term. © 2002 Elsevier Science Ltd. All rights reserved.

Design: A prospective study with repeated measures performed on 3 days along with comparisons of groups presenting different back strength and/or back muscle fiber composition. Setting: A biomechanics laboratory within a rehabilitation center. Participants: Forty male volunteers (20 healthy, 20 with chronic low back pain) were assessed on 3 different days to assess reliability and to make group comparisons. Thirteen healthy women were also assessed once to obtain a third group with known lower strength and different back muscle fiber composition. Interventions: Not applicable. Main Outcome Measures: Surface electromyography was recorded for 4 pairs of homologous back muscles while the subjects performed, on a dynamometer, static trunk extension efforts. Electromyographic parameters were computed to assess muscle weakness and muscle fiber composition. The reliability of the data collected across the 3 sessions and comparisons between groups were determined. Results: Electromyographic parameters generally showed good to excellent reliability, but were insensitive to differences in back muscle strength and did not appear to be related to muscle composition. Some trends were observed in the electromyographic parameters across the force levels, but the large interindividual variability impeded statistical comparisons. Conclusions: The assessment of muscle weakness and muscle fiber composition through electromyographic analysis does not appear feasible, at least on an individual basis, for the muscles of the back. © 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.

Twelve back pain patients and 12 matched controls performed isometric right and left axial rotation at 100%, 70%, 50% and 30% maximum voluntary contractions in a standing position. Surface EMG activity of rectus abdominis, external oblique, internal oblique, latissimus dorsi, iliocostalis lumborum and multifidus were recorded bilaterally. The primary torque in the transverse plane and the coupling torques in sagittal and coronal planes were measured. Results showed that there was a trend (P = 0.08) of higher flexion coupling torque during left axial rotation exertion in back pain patients. Higher activity for external oblique and lower activity for multifidus was shown during left axial rotation exertion in back pain group when compared to the control group. In right axial rotation, back pain patients exhibited lesser activity of rectus abdominis at higher levels of exertion when compared with matched controls. These findings demonstrated that decreased activation of one muscle may be compensated by overactivity in other muscles. The reduced levels of activity of the multifidus muscle during axial rotation exertion in back pain patients may indicate that spinal stability could be compromised. Future studies should consider these alternations in recruitment patterns in terms of spinal stability and internal loading. The findings also indicate the importance of training for coordination besides the strengthening of trunk muscles during rehabilitation process. © 2002 Orthopaedic Research Society.

Ten healthy subjects with 10 patients with patellofemoral pain syndrome (PFPS) performed an isometric leg press for 60 seconds at 60% MVIC with data collected using surface EMG. The power spectrum was analyzed and the extracted median frequency normalised to calculate a linear regression slope for each muscle. A repeated measures ANOVA revealed no significant differences, neither between the groups (P = 0.592) nor the muscles (P = 0.434). However, the slopes for the VMO and VL were different between the two groups with similar slopes for the RF. There was much larger variability of MF values in the PFPS group. The VMO:VL ratio calculated from these slopes for the healthy subjects was 1.17 and for the PFPS group was 1.78. These results may indicate unusual features in the fatigue indices of the quadriceps in PFPS. © 2001 Harcourt Publishers Ltd.

During these tasks, especially in standing, other abdominal trunk muscles are also active. The abdominal trunk muscles acting across multiple segments of the lumbar spine function in isolation or in synergy to create flexion torques. It is suggested that co-activation patterns of the trunk muscles are able to control the axis of rotation of the extension torque and also provide multi-segmental stability of the spine. The purpose of this study was to examine the fatigue responses in 4 asymptomatic individuals to a sustained isometric extension task of the trunk muscles evaluating the shifts in the median frequency of the electromyographic (EMG) signal. This study suggests that in asymptomatic subjects, the more superficial abdominal muscles (External Oblique and Rectus Abdominis) increased in activity as the test progressed. There was large inter-individual variation in both amplitude and median frequency changes. Rectus abdominis and the back extensors demonstrated characteristics of fatigue during the task. Studies to test for any characteristic trends in whether specific trunk muscles fatigue in standing is a feature in chronic LBP, invites a formal investigation. © 2001 Harcourt Publishers Ltd.

Before and after the intervention, static strength and dynamic muscular endurance in shoulder muscles were measured on a Cybex II dynamometer. Muscle activity in shoulder muscles was monitored via surface EMG. The signal amplitude ratio between the active and passive phase of repeated contractions indicated the ability to relax. Pain at present, pain in general and pain at worst were measured on visual analogue scales. After training, within group comparisons showed that the training groups rated less pain, and in the strength training group ratings of pain at worst differed from the non-training group. Using the non-training group as a reference, static strength increased in the strength and endurance training groups and muscular endurance in all training groups. The study indicates that regular exercises with strength, endurance or co-ordination training of neck/shoulder muscles might alleviate pain for women with work-related trapezius myalgia.

However, variability of the H-reflex precluded its routine application. The purpose of this study is to evaluate the test-retest and within-subject reliability of the soleus H-reflex tested in three different positions. Subjects: Seven men and eight women healthy volunteerd (20-50 y) with no history of significant low back pain or radiculopathy consented to the study. Methods: The soleus H-reflexes for both lower extremities were elicited and recorded using Cadwell 5200-A EMG unit and surface recording. The tibial nerve was electrically stimulated at the popliteal fossa using 0-5 ms., 0.2 pps pulses at intensity equivalent to H-max. Each subject was tested randomly in three different positions: pronelying, free standing, and standing while lifting 20% of his/her body weight. Signal were amplified (1-5 K) using surface electrodes applied on the soleus muscle at midline and 3 cm below the gastrocnemius musculotendinous junction. The peak-to-peak amplitude and onset latencies of four separate traces were averaged for each trial. Subjects were re-tested within 10 days by the same tester following the same protocol. Results: Test-retest reliability of the H-reflex amplitude ranged from r = .29 in prone position to r = .56 in the loading position. Within day reliability of the H-amplitude was high between the three different positions and ranged from r = .56 to r = .97. The test-retest reliability of the H-latency were extremely high and robust, with the coefficients ranged from r = .92 to r = .94. Also the within day reliability of the H-latency ranged from r = .96 to r = .99. Conclusions: Results indicated that, when the H-amplitude is the measure of choice, testing the H-reflex in standing and loading positions is more reliable than testing in pronelying. Also testing the subject during various procedures in the same session is more reliable than testing subject in different days/sessions. The H-latency is highly reliable in all three testing positions.

Static and median EMG activity level, number of EMG gaps and gap time were determined. The variability of these variables over the workday was examined by calculating the coefficient of variation (CV) and the intraclass correlation coefficient (ICC) of 1-h consecutive recording periods. All variables except gap time showed acceptable reliability (ICC = 0.69-0.78), i.e. the largest fraction of variance in the data set was due to intersubject variance, despite relatively large hour-to-hour variation (CV = 0.21-.62). The EMG activity level in the trapezius muscles was low (static activity level < 1% EMGmax), despite the high prevalence of shoulder and neck pain for both groups of workers. In addition to the work recordings, tests were performed to determine intersubject variation in muscle activity when adopting a standardized resting posture, and in a dynamic muscle activity pattern during paced arm movement. Neither the EMG variables from the work recordings nor the tests with EMG recording indicated higher trapezius EMG activity levels for workers with pain in the shoulders and neck in this study. The low EMG levels are interpreted to indicate a low risk of developing shoulder and neck complaints due to biomechanical exposure for both groups of workers. The possibility of pain-initiating mechanisms, associated with stress and not mediated through muscle activity, is considered in the discussion.

Twenty healthy persons and 20 patients with chronic LBP were asked to perform symmetrical and asymmetric tasks. The patients with LBP were tested in the weeks immediately before and after 12 weeks of LBP rehabilitation. Tasks include "carrying" weights up and down and with a 45degree left rotation. Eight-channel surface electromyographic electrodes were placed on the surface of paraspinal muscles over the lumbar region. Correlations between the right and left corresponding muscles and between values before and after treatment were determined. Lifting capacity for patients with LBP were also measured before and after treatment. Results from electromyographic profiles showed that the muscle activity strategies varied between healthy persons and patients with LBP. The correlation coefficients for spinal muscles have shown very reproducible intrasubject muscle contraction synergies. Unbalanced electromyographic patterns found in patients with LBP given symmetrical tasks were not affected by rehabilitation treatment.

One has to consider this fact regarding the still growing number of musculo-skeletal diseases. Aim of study: The influence of several preventive therapies (coordination training in spacecurl, kinaesthetics/back protective patient transfer) has been investigated with regard to coordination, back pain and quality of life in a randomised controlled study. Methods: We used an assessment-set consisting of a specially devised questionnaire regarding job demands, sports activity and back pain and the WHOQOL-BREF for control of quality of life. These methods were combined with body surface electromyography and posturography. Those methods enabled us to determine parameters such as coordination, back pain and quality of life at 3 different stages (untrained individuals) and 4 points (trained individuals) respectively. Results: Trained individuals showed a significant reduction of back pain frequency (p = 0.016) before and after training. In comparison there was no difference in untrained individuals. Furthermore trained individuals showed an increase in quality of life of 5.4% (p = 0.028), whereas again there was no difference in untrained individuals. Somatic diagnostics (body surface electromyography, posturography) showed significant changes only in the trained group. Conclusion: The used coordination training program is enhancing coordination and reducing back pain whilst having a positive effect upon the quality of life of an individual.

Short-latency reflex responses were evoked in the masseter and temporalis muscles by fast stretches (1 mm displacement, 10 ms ramp time) before, during and 15 min after a period with tonic pain. In Expt. I, a dose of 5.8% hypertonic or 0.9% isotonic (control) saline was infused in random order into the left masseter for up to 15 min (n = 12). The level of excitation of the left masseter was kept constant at 15% of maximal effort by visual feedback and on-line calculation of the root-mean-square value of the surface electromyogram (sEMG). In Expt. II, a dose of 5.8% saline was infused into the left masseter but with feedback from the right masseter sEMG (n = 12). In Expt. III, both sEMG and intramuscular (im) EMG was recorded from the left and right masseter muscles. The feedback was from either the sEMG or imEMG of the left masseter in which 5.8% saline was infused (n = 12). In all experiments, subjects continuously rated their perceived pain intensity on a 10-cm visual analogue scale (VAS). Infusion of 5.8% saline caused moderate levels of pain (mean VAS 4.9-5.0 cm) whereas infusion of 0.9% saline was almost pain-free (mean VAS 0.3 cm). The pre-stimulus EMG activity in the masseter, which served as the feedback muscle during the recording, was constant across the different conditions. During painful infusion of 5.8% saline in Expts. I and III, the pre-stimulus sEMG activity in the non-painful masseter was significantly higher than baseline when the sEMG on the painful side was used as feedback signal, and in Expt. II significantly lower on the painful side when the non-painful side served as feedback signal (Student-Newman-Keuls: P < 0.05). Isotonic saline did not affect the pre-stimulus sEMG activity or the jaw-stretch reflex parameters. The peak-to-peak amplitude of the stretch reflex in the painful masseter normalized to the pre-stimulus EMG activity was significantly higher during the pain conditions compared with the pre- and post-infusion conditions in all experiments. These results indicate that experimental jaw-muscle pain facilitates the short-latency (8-9 ms), probably monosynaptic, jaw-stretch reflex as revealed by both sEMG and imEMG. This effect could not be accounted for by variability in pre-stimulus EMG activity. An increased sensitivity of the fusimotor system at this level of static muscle excitation is suggested as a possible mechanism, which could contribute to an increased stiffness of the jaw-muscles during pain.

A lack of synergy in the quadriceps muscles results in a dynamic misalignment of the patella, which in turn produces pain. AKP rehabilitative therapy consists of conservative treatment whose main objective is to strengthen the Vastus Medialis. The aim of this article is to study the quadriceps muscle control strategy in AKP patients during an isokinetic exercise. Analysis of the muscle activation strategy is important for an objective measurement of the knee functionality in that it helps to diagnose and monitor the rehabilitative treatment. Surface electromyography (EMG) from the three superficial muscles of the femoral quadriceps during a concentric isokinetic exercise has been analyzed along with the signals of knee joint position and torque. A group of 12 AKP patients has been compared with a group of 30 normal subjects. Analysis of the grand ensemble average of the EMG linear envelopes in AKP patients reveals significant modifications in Vastus Medialis activity compared to the other quadriceps muscles. In order to study the synergy of the muscles, temporal identifiers have been associated to the EMG linear envelopes. To this end, EMG linear envelope decomposition in Gaussian pulses turned out to be effective and the results highlight an appreciable delay in the activation of the Vastus Medialis in AKP patients. This muscular unbalance can explain the abnormal motion of the patella.

It is well accepted that spinal stability is dependent on the contribution of the muscular system. However, the ability of this system to satisfy the requirements of stability is dependent on its controller - the central nervous system (CNS). The CNS must predict the outcome of movements to plan appropriate strategies of muscle activity to meet the demands of internal and external forces, and initiate appropriate responses to unexpected disturbances. In addition, this complex control of stability must occur in conjunction with control of the trunk muscles for other functions, such as respiration. For the CNS to cope with athletic performance the coordination of these parameters must be streamlined. Yet evidence suggests that when spinal pain is present the strategies used by the CNS to control trunk muscles may be altered. The mechanism for these changes is poorly understood but may be due to changes at many levels of the CNS. For rehabilitation of the athlete with spinal pain it is critical that the motor control of stability is optimised. Furthermore, this must be coordinated with the multiple other functions of trunk muscles, including respiration.

According to the pain adaptation model the activity of the painful ECU muscle may be inhibited and its antagonist activity increased during wrist extension performed as a pre-defined low-force ramp. The pre-defined low force may then be maintained by increased activity in the pain-free synergist muscles such as the extensor carpi radialis (ECR) muscle. Nine females (31-47 years old) participated in the study. Maximal voluntary contraction (MVC) of the wrist extensors was performed. A catheter was inserted into the ECU muscle to allow the injection of hypertonic saline to evoke muscle pain, and a concentric needle was inserted for the recording of MU activity. Surface electromyograms were recorded from a synergist and an antagonist (ECR and flexor carpi radialis) to the painful ECU muscle. A force ramp of isometric wrist extensions up to 10% MVC, with a force increase of 1% MVC . s-1, were performed followed by 60 s of sustained contraction at 10% MVC. The number of MUs recruited was almost identical for baseline and with pain, and no effect of experimental muscle pain was found on the properties of the MUs (amplitude, area) or their firing characteristics (mean firing rate, firing variability) during low-force ramp contraction. During the sustained 10% MVC, no effect of pain was found for concentric or surface EMG of the forearm muscles. At low force levels no pain-induced modulations were found in MU activity, when the mechanical condition was similar to that of a control situation.

Galvani who took credit for it. J. Swammerdam had already shown the Duke of Tuscany in 1658 the mechanics of muscular contraction. Even if 'electrology or localised electrisation' - the original terminology for electromyography (EMG) - contained the oldest biological scientific detection and measuring techniques, EMG remained a 'supporting' measurement with limited discriminating use, except in conjunction with other methods. All this changed when EMG became a diagnostic tool for studies of muscle weakness, fatigue, pareses, paralysis, and nerve conduction velocities, lesions of the motor unit or for neurogenic and myogenic problems. In addition to the measurement qualities, the electrical signal could be induced as functional electrical stimulation (FES), which developed as a specific rehabilitation tool. Almost in parallel and within the expanding area of EMG, a speciality developed wherein the aim was to use EMG for the study of muscular function and coordination of muscles in different movements and postures. Kinesiological EMG and therewith surface EMG can be applied in studies of normal muscle function during selected movements and postures; muscle activity in complex sports; occupational and rehabilitation movements; isometric contraction with increasing tension up to the maximal voluntary contraction, evaluation of functional anatomical muscle activity (validation of classical anatomical functions); coordination and synchronization studies (kinematic chain); specificity and efficiency of training methods; fatigue; the relationship between EMG and force; the human-machine interaction; the influence of material on muscle activity, occupational loading in relation to lower back pain and joint kinematics. Within these various applications the recording system (e.g. the signal detection, the volume conduction, signal amplification, impedance and frequency responses, the signal characteristics) and the data-processing system (e.g. rectification, linear envelope and normalization methods) go hand in hand with a critical appraisal of choices, limits and possibilities.

A quick-release method in four directions of isometric trunk exertions was used to study the muscle response patterns in 17 patients with chronic low back pain and 17 matched control subjects. Objectives. It was hypothesized that patients with low back pain would react to sudden load release with a delayed muscle response and would exhibit altered muscle recruitment patterns. Summary of Background Data. A delay in erector spinae reaction time after sudden loading has been observed in patients with low back pain. Muscle recruitment and timing pattern play an important role in maintaining lumbar spine stability. Methods. Subjects were placed in a semiseated position in an apparatus that provided stable fixation of the pelvis. They exerted isometric contractions in trunk flexion, extension, and lateral bending. Each subject performed three trials at two constant force levels. The resisted force was suddenly released with an electromagnet and electromyogram signals from 12 trunk muscles were recorded. The time delay between the magnet release and the shut-off or switch-on of muscle activity (reaction time) was compared between two groups of subjects using two-factor analysis of variance. Results. The number of reacting muscles and reaction times averaged over all trials and directions showed the following results: For healthy control subjects a shut-off of agonistic muscles (with a reaction time of 53 msec) occurred before the switch-on of antagonistic muscles (with a reaction time of 70 msec). Patients exhibited a pattern of co-contraction, with agonists remaining active (3.4 out of 6 muscles switched off) while antagonists switched on (5.3 out of 6 muscles). Patients also had longer muscle reaction times for muscles shutting off (70 msec) and switching on (83 msec) and furthermore, their individual muscle reaction times showed greater variability. Conclusions. Patients with low back pain, in contrast to healthy control subjects, demonstrated a significantly different muscle response pattern in response to sudden load release.

Subjects continuously scored the pain intensity on a 10-cm visual analogue scale. Mastication ipsilateral and contralateral to the infusion side was quantitatively assessed with the use of jaw-tracking and electromyograph recordings of jaw-closing muscles before, during, and after periods of constant muscle pain intensity. The maximum voluntary occlusal force (MVOF) during short static contractions also was monitored. Jaw movements and electromyographic data were divided into single masticatory cycles and analyzed on a cycle-by-cycle basis to account for intercycle variability. In all subjects, tonic infusion caused a deep localized pain at a clinically relevant intensity (mean VAS +/- SE, 4.6 +/- .3 cm). MVOF was significantly affected by muscle pain (P < .0005), with significantly lower MVOF during pain compared to prepain and postpain (P < .05). In a significant number of masticatory cycles, the averaged electromyograph activity of all jaw-closing muscles during their agonist function was decreased for both ipsilateral and contralateral painful mastication (P < .05). These electromyographic changes are probably a reflection of the natural bilateral recruitment pattern of jaw-closing muscles during mastication. Significant changes in jaw movements during painful mastication could not be detected with the present jaw-tracking device, but further studies with more accurate and sensitive devices are needed.

These appliances provide the practitioner with a non-invasive, reversible form of intervention to manage the patient's symptoms. Literature on the use and effectiveness of these appliances has become readily available and now requires retrospective evaluation. However, comparison of results from studies making use of interocclusal orthopedic appliance therapy is difficult due to the employment of various outcome measurement scales, subjective evaluation of patient outcome, and variability in reporting of treatment outcomes. The aim of this paper is to review the effects and success rates of the various appliances reported in the literature and provide the practitioner with useful information that may be of assistance in the prediction of outcome and success of splint appliance therapy.

A cross-sectional study in patients with recurrent/chronic low back trouble and healthy control subjects. Objective. To evaluate the effect of paraspinal muscle fatigue on the ability to sense a change in lumbar position. Summary of Background Data. Protection against spinal injury requires proper anticipation of events, appropriate sensation of body position, and reasonable muscular responses. Lumbar fatigue is known to delay lumbar muscle responses to sudden loads. It is not known whether the delay is because of failure in the sensation of position, output of the response, or both. Methods. Altogether, 106 subjects (57 patients with low back trouble [27 men and 30 women] and 49 healthy control subjects [28 men and 21 women] participated in the study. Their ability to sense a change in lumbar position while seated on a special trunk rotation unit was assessed. A motor rotated the seat with an angular velocity of 1degreeper second. The task in the test involved reacting to the perception of lumbar movement (rotation) by releasing a button with a finger movement. The test was performed twice, before and immediately after a fatiguing procedure. During the endurance task, the participants performed upper trunk repetitive extensions against a resistant, with a movement amplitude adjusted between 25degreeflexion and 5degreeextension, until exhaustion. Results. Patients with chronic low back trouble had significantly poorer ability than control subjects on the average to sense a change in lumbar position (P = 0.007), which was noticed before and after the fatiguing procedure. Lumbar fatigue induced significant impairment in the sensation of position change (P < 0.000001). Conclusions. Lumbar fatigue impairs the ability to sense a change in lumbar position. This feature was found in patients and control subjects, but patients with low back trouble had poorer ability to sense a change in lumbar position than control subjects even when they were not fatigued. There seems to be a period after a fatiguing task during which the available information on lumbar position and its changes is inaccurate.

To quantify the variability in lifting motions, trunk moments, and spinal loads associated with repeated lifting exertions and to identify workplace factors that influence the biomechanical variability. Design. Measurement of trunk dynamics, moments and muscle activities were used as inputs into EMG assisted model of spinal loading. Background. Traditional biomechanical models assume repeated performance of a lifting task produces little variability in spinal load because the assessments overlook variability in lifting dynamics and muscle coactivity. Methods. Five experienced and seven inexperienced manual materials handlers performed 10 repeated lifts at each combination of load weight, task asymmetry and lifting velocity. Results. Box weight, task asymmetry and job experience influenced the magnitude and variability of spinal load during repeated lifting exertions. Surprisingly, experienced subjects demonstrated significantly greater spinal loads and within-subject variability in spinal load than inexperienced subjects. Trial-to-trial variability accounted for 14% of the total variation in compression overall and 32% in lateral shear load. Although the mean spinal load was safely below the NIOSH recommended limit; due to variability about the mean, more than 20% of the lifts exceeded the recommended limit. Conclusion. Spinal load changed markedly from one exertion to the next despite identical task requirements. Trial-to-trial variability in kinematics, kinetics, and spinal load were influenced by workplace factors, and may play a role in the risk of low-back pain.

Study Design: Abdominal and back extensor muscle activity in association with upper limb movement was compared among three speeds of movement and between people with and without low back pain. Participants: Fourteen subjects with a history of recurrent low back pain and a group of age- and sex-matched control subjects. Measures: The onsets of electromyographic activity of the trunk and limb muscles, frequency of trunk muscle responses, and angular velocity of arm movements. Results: Early activation of transversus abdominis (TrA) and obliquus internus abdominis (OI) occurred in the majority of trials, with movement at both the fast and intermediate speeds for the control group. In contrast, subjects with low back pain failed to recruit TrA or OI in advance of limb movement with fast movement, and no activity of the abdominal muscles was recorded in the majority of intermediate speed trials. There was no difference between groups for slow movement. Conclusion: The results indicate that the mechanism of preparatory spinal control is altered in people with lower back pain for movement at a variety of speeds.

The aim of the present study was to investigate and compare motor function during controlled, low load, repetitive work together with chronic or acute experimental neck-shoulder pain. The clinical study was performed on workers with (n = 12) and without (n = 6) chronic neck-shoulder pain. In the experimental study, experimental muscle pain was induced in healthy subjects by intra-muscular injection of hypertonic saline into the trapezius muscle (n = 10). The assessed parameters related to motor performance were: work task event duration, cutting forces, surface electromyogram (EMG) activity in four shoulder muscles, displacement of the centre of pressure, and arm and trunk 3D movements. For controlled cutting force levels, chronic and acute experimental pain provoked a series of changes: a decreased working rhythm and a protective reorganisation of muscle synergy (experimental study), higher EMG frequency contents which may indicate altered motor unit recruitment, and greater postural activity and a tendency towards increased arm and trunk movements. These pain-related changes can play a role in the development of MSD. The present clinical and experimental study demonstrated similar interactions between motor co-ordination and neck-shoulder pain in occupational settings. We therefore suggest that this experimental model can be used to study mechanisms related to MSD. Information on such modulatory processes may help in the design of new strategies aimed at reducing the development of MSD.

The reliability of the median frequency parameters was investigated for EMG-recording sites at L1 and L5 right and left on the erector spinae. The reliability of subjective fatigue ratings of the back muscles (Borg CR-10 scale) and of maximal trunk extension torque (MVC) was also investigated. Eleven subjects with healthy backs performed a 45-s isometric trunk extension at 80% of MVC twice a day, on three different days. Two-factor analysis of variance was made to obtain the different variances from which the standard error of measurement (SEM) and the intra class correlation coefficient (ICC) were calculated. The SEM within-day was somewhat lower than that between-days. Both were about the same at all four electrode sites. The 95% confidence interval for the studied variables was for the initial median frequency +/- 10 Hz, for the slope +/- 0.4-0.5%/s, for the MVC +/- 36 Nm and for the Borg ratings +/- 1.6. We conclude that, with the presently used method, changes or differences within these limits should be regarded as normal variability. The slope may be of limited value because of its large variability. Whether the low intraclass correlation coefficient for the EMG parameters in the presently studied test group implies a low potential in discriminating subjects with back pain can not be decisively concluded.

Background: RMD is a rare autosomal-dominant inherited muscle disorder. Individuals complain of muscle stiffness, exercise-induced muscle pain, and cramp-like sensations. The characteristic feature of RMD is increased mechanical muscle irritability, which is electrically silent in electromyographic examinations. Methods: Forty-six individuals from two unrelated German kindreds with RMD were examined. Linkage analysis to the RMD locus on chromosome 1q41-q43 was performed. Results: In kindred A, 15 individuals from four generations, and in kindred B, four individuals from three generations had clinical features of RMD. The most consistent clinical findings were percussion-induced rapid muscle contractions (PIRCs) and muscle mounding, which were present in all 19 affected individuals. Only 12 individuals exhibited muscle rippling, indicating that rippling is not always present in RMD. Twelve of 19 individuals had muscle-related complaints, primarily exertional cramps and stiffness. The mean age at the onset of complaints was 22 years (range, 5 to 54 years). Seven of 19 individuals showed only mechanical-induced muscle irritability but did not have muscular symptoms. Genetic analysis excluded linkage to the RMD locus on chromosome 1q4 in both kindreds. Conclusions: The phenotype of RMD is variable but generalized PIRCs are the most obvious and reliable clinical feature of RMD. Diagnostic criteria of RMD should include generalized PIRCs in addition to muscle mounding, rippling, and creatine kinase elevation.

Thirteen volunteers, seen by a physical therapist, gave informed consent. Surface EMG electrodes were placed on involved and uninvolved upper trapezius muscles. Root mean squared EMG activity was measured. Visual analog scales (VASs) for pain were used for each side. Reliability data indicated high ICC (2,1) but also large SEMs and CVs. EMG activity increased from resting to shrugging to abducting positions. Participants perceived greater pain on the involved side than the uninvolved side. EMG readings for individuals were consistent, however, between participants. EMG had high variability. Although participants' VAS scores were consistent with their reports of unilateral neck pain, surface EMG readings did not support the existence of increased muscle activity on the involved side.

He had no familial history of hereditary disorders. In 1980 he noticed mild ataxic gait which exaggerated while he closed eyes. The symptoms increased gradually, and four years later he noticed hypoesthesia of his soles. In 1983 he was admitted to the National Center Hospital for Mental, Nervous and Muscular Disorders for the first time. Neurological examination revealed dysarthria, ataxic gait, disturbance of coordination to a slight degree, and muscle strength of the upper and lower limbs were in normal range. Mild hypoesthesia of pain and temperature sensation, and marked decrease of deep sensation and vibration of the lower extremities were demonstrated. Romberg sign was positive. EMG studies revealed low amplitude of action potential and normal motor nerve conduction velocity. Biopsy of the sural nerve showed marked decrease of both large and small myelinated fibers. In 1998 he was admitted second time for the further examination. Laboratory examination including routine blood examination, blood chemistry including CRP, TPHA, vitamin B1, B2, B12, A, E, K, hexosaminidase A in leucocyte were in normal range. CSF was normal. Genetic studies including SCA 1, 2, 3, 6, DRPLA, CMT1A, CMTX 1 were all negative. MCV of lower limbs was in normal range, though SCV was not evoked in the upper and lower limbs. MRI studies showed mild atrophy of the bilateral lobulus of the cerebellum which was not so much changed in the last 5 years. The clinical symptoms revealed dominant posterior column disturbance, ataxia and sensory neuropathy. These combination was riot described in the previous literature, and this case may be a new variant of the spinocerebellar degeneration.

The aim of this model is to obtain a tool for analyzing the relations between forces in muscles, ligaments and joints in the transfer of gravitational and external load from the upper body via the sacroiliac joints to the legs in normal situations and pathology. The study of the relation between muscle coordination patterns and forces in pelvic structures, in particular the sacroiliac joints, is relevant for a better understanding of the aetiology of low back pain and pelvic pain. The model comprises 94 muscle parts, 6 ligaments and 6 joints. It enables the calculation of forces in pelvic structures in various postures. The calculations are based on a linear/non-linear optimization scheme. To gain a better understanding of the function of individual muscles and ligaments, deviant properties of these structures can be preset. The model is validated by comparing calculations with EMG data from the literature. For agonistic muscles, good agreement is found between model calculations and EMG data. Antagonistic muscle activity is underestimated by the model. Imposed activity of modelled antagonistic muscles has a minor effect on the mutual proportions of agonistic muscle activities. Simulation of asymmetric muscle weakness shows higher activity of especially abdominal muscles. Copyright (C) 1999 Elsevier Science Ltd.

The reliability of these spectral parameters is important in determining the validity of this evaluation tool. Two groups of eight subjects, with no history of back pain, were measured: the first group every day for one week; the second group one day per week for four weeks. During each session, subjects performed a 30-second isometric fatiguing contraction of the back extensors at 60% MVC followed by a 60-second rest and a 10-second repeat contraction. The intraclass correlation coefficient (ICC) did not demonstrate high reliability (ICC<0.6) for the rate of median power frequency (MedPF) change (Hz/s), the magnitude of the recovery (Hz) and differences between the dominant and the non-dominant sides within a subject. However, the initial MedPF (Hz) of the fatigue and repeat contractions demonstrated excellent reliability (ICC>0.8) with five or more repeated measures. The practical implication of this work is that the experimental condition must have sufficiently large changes in MedPF (signal)-at least larger than the variability inherent in the MedPF (noise)-to constitute a valid measure.

Electrical and mechanical stimulation of the lumbar supraspinous ligament of three patients with L4-L5 spinal deficits and of the feline model, respectively, was applied while recording electromyography on the multifidus muscles. Objectives. To determine if mechanoreceptors in the human spine can reflexively recruit muscle force to stabilize the lumbar spine, and to demonstrate, in the feline model, that such ligamento-muscular synergy is elicited by mechanical deformation of the lumbar supraspinous ligament (and possibly of other spinal ligaments), the facet joint capsule, and the disc. Summary of Background Data. The literature repeatedly confirms that ligaments have only a minor mechanical role in maintaining spine stability, and that muscular co-contraction of anterior and posterior muscles is the major stabilizing mechanisms of the spine. The literature also points out that various sensory receptors are present in spinal ligaments, and that the ligaments are innervated by spinal and autonomic nerves. Data that describe how ligaments and muscles interact to provide stability to the spine were not found. Methods. The supraspinous ligament at L2-L3 and L3-L4 was electrically stimulated in three patients undergoing surgery to correct designs at L4-L5. Electromyography was performed from the multifidus muscles at L2-L3 and L3-L4, bilaterally. In 12 cats, the supraspinous ligaments from L1-L2 to L6-L7 were mechanically deformed, sequentially, while electromyography was performed from the multifidus muscles of the six levels. Loading of the ligament was applied before and after each of the two vertebrate were externally fixed to prevent motion. Results. Electromyograms were recorded from the multifidus muscles, bilaterally, in the two of the three patients, demonstrating a direct relationship to receptors in the supraspinous ligament. Electromyograms were recorded from the feline multifidus muscle with mechanical loading of the supraspinal ligament at each of the L1-L2 to L6-L7 motion segments. In the free-spine condition the largest electromyographic discharge was present in the level of ligament deformation, and lower electromyographic discharge was recorded in two rostral and caudal segments. After immobilizing any two vertebrae, loading of the ligament resulted in electromyographic discharge in the muscles of the same level and at least one level above and/or below. Conclusions. Deformation or stress in the supraspinous ligament, and possibly in other spinal ligaments, recruits multifidus muscle force to stiffen one to three lumbar motion, segments and prevent instability. Strong muscular activity is seen when loads that can cause permanent damage to the ligament are applied, indicating that spastic muscle activity and possibly pain can be caused by ligament overloading.

The present human study investigates the influence of experimental muscle pain on resting, static, and dynamic muscle activity. In the resting and static experiments, the electromyography (EMG) activity and the contraction force of m. tibialis anterior were assessed before and after injection of 0.5 ml hypertonic saline (5%) into the same muscle. In the dynamic experiment, injections of 0.5 ml hypertonic saline (5%) were performed into either m. tibialis anterior (TA) or m. gastrocnemius (GA) and the muscle activity and co-ordination were investigated during gait on a treadmill by EMG recordings from m. TA and m. GA. At rest no evidence of EMG hyperactivity was found during muscle pain. The maximal voluntary contraction (MVC) during muscle pain was significantly lower than the control condition (P < 0.05). During a static contraction at 80% of the pre-pain MVC muscle pain caused a significant reduction in endurance time (P < 0.043). During dynamic contractions, muscle pain resulted in a significant decrease of the EMG activity in the muscle, agonistic to the painful muscle (P < 0.05), and a significant increase of the EMG activity of the muscle, antagonistic to the painful muscle (P < 0.05). Muscle pain seems to cause a general protection of painful muscles during both static and dynamic contractions. The increased EMG activity of the muscle antagonistic to the painful muscle is probably a functional adaptation of muscle co-ordination in order to limit movements. Modulation of muscle activity by muscle pain could be controlled via inhibition of muscles agonistic to the movement and/or excitation of muscles antagonistic to the movement. The present results are in accordance with the pain-adaptation model (Lund, J.P., Stohler, C.S. and Widmer, C.G. In: H. Vaeroy and H. Merskey (Eds.), Progress in Fibromyalgia and Myofascial Pain. Elsevier, Amsterdam, 1993, pp. 311-327.) which predicts increased activity of antagonistic muscle and decreased activity of agonistic muscle during experimental and clinical muscle pain.

The study aimed to clarify whether the therapeutic success of an infrapatellar bandage placed above the tibial tubercle in the treatment of patellar chondropathy is based on altered knee joint loads during specific movements. Design. In a clinical trial the influence of the bandage on kinetic and EMG variables is investigated. Background. Although the used bandage is not a supporting device, the patients report an instant improvement. Thus neurological mechanisms are hypothesized as capable of pain reduction by changing the neuromuscular movement coordination or sensation thresholds. Methods. Ten patients performed three different movements (running, drop jump, walking downstairs), before and after attaching the bandage, while kinematic, dynamic, and EMG data were acquired. After calculating the intersegment moment of the knee joint, different kinetic and EMG parameters were combined to the dependent MANOVA procedure. Results. The neuromuscular activity during drop jump was reduced significantly (P < 0.1) wearing the bandage while, apart from individual changes, no general alteration of the knee joint loads could be statistically confirmed. Conclusions. The effect of the examined infrapatellar bandage is not a consequence of a decreased joint load due to a general movement adaptation, but is probably due to a neural influence on the nociception.

To demonstrate the influence of different types of lifting belts on trunk motion, muscle activity and spine loading during symmetric and asymmetric lifting exertions. Design. In vivo measurements were achieved representing lifting dynamics, applied trunk moments and myoelectric activity. Dynamic spinal loads were determined from a validated biomechanical model of lifting. Background. There is a great deal of controversy as to whether lifting belts are a benefit or a liability to manual materials-handling activities. A review of the literature demonstrates that there is a large amount of conflicting evidence and few definitive, well-executed studies upon which to base an opinion regarding these devices. Methods. Fifteen subjects lifted boxes of 14 kg and 23 kg from sagittally symmetric and asymmetric origins to an upright posture. Dynamic trunk motions, lifting moments, myoelectric activity and modelled spinal loads were examined as a function of three belt styles (elastic, leather, and orthotic) and compared with results from a no-belt condition. Results. Lifting belts reduced peak trunk angles, velocities and accelerations in the sagittal, lateral and transverse planes. However, only the elastic belt successfully reduced trunk motions in all three dimensions. The orthotic belt significantly increased the lifting moment associated with a given weight. A minor redistribution in muscle activity was observed when wearing an elastic belt. A statistically significant reduction in spinal load was associated with the elastic belt. However, a great deal of variability between subjects was noted. Some subjects experienced increased spinal load while wearing the elastic lifting belt. Conclusions. These results demonstrate that the biomechanical operation of lifting can be influenced by the type of lifting belts used.

This prospective study evaluated the abdominal muscle activity during the isometric bent knee curl and double straight leg lowering exercise. Objectives. To compare the magnitude of the electromyographic activity across the curl and double straight leg lowering exercise and determine if the muscle synergies were specific to a given exercise. Summary of Background Data. Abdominal muscle strengthening exercises are frequently recommended in the prevention and rehabilitation of individuals with low back pain. Previous studies comparing the curl exercise with the double straight leg lowering exercise did not support the notion that the double straight leg lowering exercise is more demanding on the abdominal muscles. No previous study examined these two exercises while maintaining a constant pelvic position. Methods. Fifteen male subjects had the electromyographic activity of the rectus abdominis, the external oblique, and the internal oblique abdominal muscles evaluated during the curl and double straight leg lowering exercise. The same position of the posterior pelvic tilt was maintained between each exercise using feedback from an electrogoniometer attached to the pelvis. Results. The double straight leg lowering exercise resulted in significantly greater activation of the abdominal muscles compared with the curl. Two abdominal muscle synergies emerged during the double straight leg lowering exercise: synergy I exhibited high rectus abdominis, high external oblique, and low internal oblique muscle activity, whereas synergy II exhibited low rectus abdominis, high external oblique, and high internal oblique. Conclusions. The results support the use of the double straight leg lowering with the posterior pelvic tilt for achieving greater abdominal muscle coactivation in an exercise program.

Surface electromyographic evaluation revealed constant tonic activity of multiple upper and lower arm muscles at rest, that was not distractible. Voluntary and passive movement of the elbow or wrist resulted in high amplitude EMG activity, with motor grouping at 11 Hz at the elbow and 8 Hz at the wrist. Although a diagnosis of psychogenic dystonia was entertained, the stereotyped nature of the movement disorder and lack of variability on clinical and surface EMG evaluation support an organic disorder that was temporally-related to an electrical injury.

Activity of the trunk muscles is essential for maintaining stability of the lumbar spine because of the unstable structure of that portion of the spine. A model involving evaluation of the response of the lumbar multifidus and abdominal muscles to leg movement was developed to evaluate this function. Subjects. To examine this function in healthy persons, 9 male and 6 female subjects (mean age=20.6 years, SD=2.3) with no history of low back pain were studied. Methods. Fine-wire and surface electromyography electrodes were used to record the activity of selected trunk muscles and the prime movers for hip flexion, abduction, and extension during hip movements in each of those directions. Results. Trunk muscle activity occurring prior to activity of the prime mover of the limb was associated with hip movement in each direction. The transversus abdominis (TrA) muscle was invariably the first muscle that was active. Although reaction time for the TrA and oblique abdominal muscles was consistent across movement directions, reaction time for the rectus abdominis and multifidus muscles varied with the direction of limb movement. Conclusion and Discussion. Results suggest that the central nervous system deals with stabilization of the spine by contraction of the abdominal and multifidus muscles in anticipation of reactive forces produced by limb movement. The TrA and oblique abdominal muscles appear to contribute to a function not related to the direction of these forces.

However, one important measure of the coordinated activity between the scapular rotators, their timing or temporal recruitment pattern, remains undetermined. The purposes of this study were to 1. provide normative data on the temporal recruitment pattern of the scapular rotators in freestyle swimmers, 2. determine the effect of a unilateral shoulder injury on this pattern, 3. determine whether these effects extend to the non-injured side, and 4. determine the effect of injury on the consistency (variability) of muscle recruitment. Surface EMG data for the upper and lower trapezius and serratus anterior were recorded bilaterally from two groups of competitive freestyle swimmers during controlled bilateral elevation in the plane of the scapula. An injured group comprising nine swimmers with unilateral shoulder pathology and a control group of nine non-injured swimmers were included. Temporal data determined for the onset of muscle activation for each muscle were then compared between groups using an ANOVA acid a one-sided F test. The results of the study indicate that in non-injured swimmers, upper trapezius is activated 217 ms prior to shoulder motion, followed by serratus anterior activation 53 ms after motion commences. Lower trapezius was not recruited until 349 ms after shoulder motion, when the arm had attained 15degreeelevation, in injured swimmers, all three muscles on the injured side displayed significantly increased variability in the timing of activation (p < 0.05), whilst the serratus anterior was significantly delayed in its activation on the non-injured side (p < 0.05). Skill hand preference was shown to have no effect on muscle recruitment. The findings of this study indicate that a relationship does exist between shoulder injury and the temporal recruitment patterns of the scapular rotators, such that injury reduces the consistency of muscle recruitment.

To automatize the lumbar physical examination with an acceptable rate of error. Design. An external skin marker method for automatizing the physical examination was developed and its ability to discriminate between normal and abnormal subjects tested in a blind clinical trial. Background. The low reproducibility of clinical findings, even among experienced doctors, has been well documented. This is of particular concern and may explain why there is such a wide variation in surgical rates across the USA (tenfold for disc herniation). Inconsistencies among physicians in the evaluation of benign low back conditions make standardization desirable. Methods. A computerized physical examination was used to evaluate patients with low back pain and compare their results with a normative database obtained from a selection of healthy subjects. A high-resolution motion analysis system tracked the movement of skin markers placed on the midline and pelvis. Surface EMG electrodes placed above L5 collected data from multifidus. From the kinematics of skin markers during flexion-extension with lifts up to 32 kg, and lateral bending with lifts up to 10 kg, the following parameters were estimated: lumbosacral angle and elongation, contribution of each lumbar segment to the lordosis reduction, relative pelvic/spine motion, and trunk velocity. First the average normal value for each estimated parameter was determined using 40 normal subjects. For each subject the difference between his parameter and the normal was processed by an expert system generating a normality index varying from zero (perfect abnormal) to one (perfect normal). To develop the expert system's rules, a preliminary group of 20 very abnormal subjects was used, such that the normality index separated them from the normals. For validation, a set of 29 back-sprain patients and another set of 42 discogram-positive patients were selected. Each subject was tested and his computerized normality index calculated without any clinician's input, then compared with the clinician's evaluation, which was taken to be the gold standard. The receiver operating characteristic technique was used to quantify the discrepancies. Results. The expert system could detect clinically abnormal subjects with accuracy (sensitivity 83-91% and specificity > 90%) while providing quantitative information on workers' functional capacities. Conclusions. Once a reference normative database is agreed upon, each patient can be compared with that reference according to the same rules, with the resulting machine classification being independent of the clinician. This eliminates the inter- and intra-clinician variability in patient follow-up. Because of the severity of the selection criteria, this study is based upon a relatively restricted number of subjects, as well as a limited normative database of 40 subjects.

Today, diagnosis and therapy are insufficient, and knowledge concerning interaction between musculoskeletal pain and motor performance is lacking. Most studies in this field have been performed under static conditions which may not represent CLBP patients' daily-life routines. A standardized way to study the sensory-motor interaction under controlled motor performances is to induce experimental muscle pain by i.m. injection of hypertonic saline. The aim of the present controlled study was to analyze and compare electromyographic (EMG) activity of and coordination between lumbar muscles (8 paraspinal recordings) during gait in 10 patients with CLBP and in 10 volunteers exposed to experimental back muscle pain induced by bolus injection of 5% hypertonic saline. When the results are compared to sex- and age-matched controls, the CLBP patients showed significantly increased EMG activity in the swing phase; a phase where the lumbar muscles are normally silent. These changes correlated significantly to the intensity of the back pain. Similar EMG patterns were found in the experimental study together with a reduced peak EMG activity in the period during double stance where the back muscles are normally active. Generally, these changes were localized ipsilaterally to the site of pain induction. The clinical and experimental findings indicate that musculoskeletal pain modulates motor performance during gait probably via reflex pathways. Initially, these EMG changes may be interpreted as a functional adaptation to muscle pain, but the consequences of chronic altered muscle performance are not known. New possibilities to monitor and investigate altered motor performance may help to develop more rational therapies for CLBP patients.

The contribution of transversus abdominis to spinal stabilization was evaluated indirectly in people with and without low back pain using an experimental model identifying the coordination of trunk muscles in response to a disturbance to the spine produced by arm movement. Objectives. To evaluate the temporal sequence of trunk muscle activity associated with arm movement, and to determine if dysfunction of this parameter was present in patients with low back pain. Summary of Background Data. Few studies have evaluated the motor control of trunk muscles or the potential for dysfunction of this system in patients with low back pain. Evaluation of the response of trunk muscles to limb movement provides a suitable model to evaluate this system. Recent evidence indicates that this evaluation should include transversus abdominis. Methods. While standing, 15 patients with low back pain and 15 matched control subjects performed rapid shoulder flexion, abduction, and extension in response to a visual stimulus. Electromyographic activity of the abdominal muscles, lumbar multifidus, and the contralateral deltoid was evaluated using fine-wire and surface electrodes. Results. Movement in each direction resulted in contraction of trunk muscles before or shortly after the deltoid in control subjects. The transversus abdominis was invariably the first muscle active and was not influenced by movement direction, supporting the hypothesized role of this muscle in spinal stiffness generation. Contraction of transversus abdominis was significantly delayed in patients with low back pain with all movements. Isolated differences were noted in the other muscles. Conclusions. The delayed onset of contraction of transversus abdominis indicates a deficit of motor control and is hypothesized to result in inefficient muscular stabilization of the spine.

This paper discusses the effect of 'sudden load' on the erector spine reaction and amplitude. Muscle responses were mediated by several factors, including fatigue, posture, expectation and rehabilitation, in chronic low back pain patients. The subjects were fatigued by holding a 20% maximum voluntary contraction for 1 min. A functional restoration program was tested for its efficacy in reducing reaction time and EMG amplitude in chronic low back pain patients. Reaction time was longer and EMG amplitude lower in patients than in their matched controls. EMG reaction time and magnitude decreased in patients after a 2-week rehabilitation program, including specific training of coordination and posture control. The results of the modelling showed higher spinal compressive load and lower shear forces when the load was expected than when the load was unexpected. The effect of sudden loads can be exacerbated if a worker is not standing on a flat surface or is fatigued. Chronic low back pain patients have less ability to protect themselves from sudden loads, but they can be trained to improve their response by means of an appropriate rehabilitation program.

Seven levels of stimulus intensity, based on individual sensory and pain thresholds, were applied and the relationship between ESPs, stimulus intensity and perception, as manifested by the subjective verbal response, was investigated. The analysis revealed that the occurrence of ESPs was not related to the stimulus intensity at the pain threshold. There were individually different patterns of progressive response to increasing current intensities within the pre-pain range in many cases. On the other hand, almost half of all the subjects investigated showed no or only occasional ESPs. In view of this variability the concept of ESPs being a nociceptive behavioural response has to be questioned.

The two different functions of TrA were evaluated in 15 subjects. The subject group included six subjects with chronic low back pain and nine subjects with no history of low back pain so that the resultant recordings were spread over a wide range for each test. The clinical test involved quantification of the ability of the subjects to specifically displace the anterior abdominal wall in a way consistent with the function of the muscle. This was evaluated by use of a device designed to measure pressure reduction as the abdomen lifted off a transducer in the prone position. The laboratory test involved determination of the onset of contraction of TrA associated with rapid upper limb movement, measured using fine-wire EMG electrodes. The parameter evaluated was the latency between the contraction of TrA and the prime mover of the limb. Data were analysed both as absolute values and as ordinal data of a three-rating scale derived from criteria based on current knowledge of the response to both tests. No significant correlation was found between the absolute magnitudes of the pressure and timing data, however, comparison of the rating scale data indicated a significant relationship between the tests and associated high level of agreement between the two measures. The results of the study indicate that a reduction in the ability to draw in the abdominal wall is related to changes in the coordination of TrA, although the magnitude of the changes were not correlated. The degree of causality between these co-varying but independent manifestations of the function of TrA is uncertain.

Among different methods of recording, averaging 10 full-wave rectified EMG responses produces results with acceptable variability and discomfort. The late temporalis exteroceptive suppression period (ES2) is reduced on average in patients with chronic tension-type headache; this finding has been reproduced by several independent laboratories. Mean duration of temporalis ES2 is also diminished, but to a lesser degree, in daily drug abuse headache and, as shown by others, in episodic tension-type headache. It is normal in migraine between attacks, cluster headache and various types of symptomatic headaches. Temporalis ES2 may be decreased in untreated patients with major depression. In healthy volunteers, temporalis ES2 duration is reduced by a short-lasting painful stimulus to peripheral limbs after a delay of 50 to 60 ms, and by a sub- motor threshold electromagnetic stimulation to the contralateral cerebral cortex after a delay of 20 to 30 ms. In contrast, long-lasting trains of peripheral painful stimuli have no effect. Various pharmacological agents are able to modify temporalis ES2. Its duration is increased by 5-HT antagonists, but decreased by 5-HT uptake blockers. Pharmacological effects may differ between controls and patients. Considering these results and available data on the anatomo-functional organization of masticatory reflexes, we postulate that temporalis ES2 is a marker of the excitability of interneuronal nets in the ponto-medullary reticular formation. In chronic tension-type headache, excitability of these interneurons is decreased because of inadequate control by the serotonergic raphe magnus nucleus and the periaqueductal gray matter. Dysfunctioning of the latter structures might be caused by abnormal limbic inputs to the brain stem. Some steps of this pathophysiological hypothesis can be verified by modern neurophysiological techniques.

The matching was done so that the physical demands from work (external exposure) were equal for both the case and the control. Each pair was also matched for gender, age, working hours, and employment time. Male (n = 18) and female workers (n = 78) employed in both manual and office work were included. Muscle activation levels and pause patterns during work and muscle activity during tests of attention, coordination, and rest were recorded by surface electromyography. The results showed consistent associations between pain and signs of increased activation of the upper trapezius for the cases in the manual group. No such associations were observed in the office group. The results are consistent with the hypothesis that muscle activation patterns may in some instances, but not in all, explain why some workers develop pain while others do not in work situations where the physical demands are similar.

This is called 'flexion-relaxation (F-R) phenomenon.' The goals of this study were (1) to evaluate the relationship between flexion angle and activity of back muscles during flexion movement and (2) to determine what the difference is between healthy subjects and patients with chronic low back pain (CLBP). Twenty-five healthy subjects (13 males and 12 females; average age, 28.3 yr) and 20 patients with CLBP (12 males and 8 females; average age, 34.1 yr) volunteered for this study. The subjects were asked to flex forward maximally from the erect position and to maintain full flexion, followed by returning to the initial upright position. Flexion angle of trunk and hip was measured during the examination. Electromyographic activity of erector spinae was also monitored simultaneously. F-R phenomenon was observed in all healthy subjects before reaching the maximum flexion. Electrical silence continued even after extending the trunk began. In contrast, no patients with CLBP demonstrated F- R phenomenon. A significant difference in muscular activities of erector spinae between the groups was obtained when returning to the erect position from the maximum flexion. Moreover, time lag between trunk and hip movement was much greater in patients than in healthy subjects. This study demonstrated that neuromuscular coordination between trunk and hip could be abnormal in patients with CLBP.

A pilot and a main study were carried out with 10 males and 20 females, respectively. The subjects performed a VDU data entry task under psychologically stressful and non-stressful conditions. Stress reactions were measured by different methods: heart rate and heart rate variability, hormonal excretion, and subjective ratings of mood and body symptoms. The stress condition caused an increase in heart rate. The low-frequency variability increased and the high-frequency variability decreased. Ratings of motivation and relaxation decreased, and subjects felt more activated. Pain and discomfort from the stomach increased. Adrenaline and noradrenaline in urine were unaffected. The majority of the subjects showed moderately increased static and median EMG levels during the stress condition. The interindividual variation in muscular reactions was large. Statistically significant increases were obtained for the myoelectric activity of the left (resting) trapezius muscle when pooling the two groups. It appears that the increase in muscle activity due to this type of mental stress is small, and factors other than 'attention-related' load may be more important. The results indicate that some individuals may be more prone to general muscle tension, making them more likely to develop symptoms and musculoskeletal pain.

A database for estimated normal spinal motion was derived using a noninvasive, high-resolution, computer-aided system, which tracks the motion of skin markers strategically placed on the spine. Forty normal subjects, selected from hundreds of possible subjects according to rigorous inclusion/exclusion criteria, were tested on the system. Objectives. Patterns of estimated spinal motion were analyzed as a function of load, age, and sex, confirming a correlation between the movement of spinal segments and the motion of skin markers. Summary of Background Data. The Workers Compensation Board of Quebec funded and supervised the experiments necessary to establish a normative reference database for a high-resolution motion analysis system that permits a noninvasive assessment of spinal function. A previous study examined the correlation between the movements of the skin markers and the underlying bony structures for trunk flexion. Skin movement cannot be random and contains information characterizing both the spine and its surrounding soft tissues. Methods. A noninvasive dynamic imaging system was used to measure normal spinal function under free movement. A high-resolution three- dimensional camera system collected basic kinematic data from strategically placed skin markers over the lumbar spine while the activity of paraspinal muscles was being recorded with surface electromyography. The measurements were analyzed for consistent, specific patterns recognizable as normal lumbar spine skin motion and reflecting normal lumbar spine function. A comparison was made with previous radiographic studies to confirm the correlation between the motion of skin markers and lumbar spine function. Results. Lumbar skin marker motion patterns in normal subjects were consistent and varied little with load; gender had no effect except in the initial phase of a movement. There was less mobility but similar coordination in older subjects. No inconsistencies with previous radiologic investigations were found for sagittal and lateral plane movement. Conclusions. Consistent patterns were found and measurements compare favorably with previous radiographic data. Results show that it is possible to estimate spinal function from the data collected from the motion of skin markers.

We studied 47 healthy subjects, (mean +/- SD, 35 +/- 10 years) using methods similar to those described by Braddom and Johnson. Only those with side-to-side latency difference less than 1.5msec were included (n = 45). Current was increased in 0.5 to 1.0 mA increments until the H-reflex amplitude maximized and then fell; on each side the response with the maximal peak-to-peak amplitude was measured for peak-to-peak amplitude and onset latency. The amplitude on the side of the smaller response was expressed as a ratio of the contralateral amplitude; this mean value (+/-SD) was 0.74 +/- 0.17. We conclude that a side- to-side amplitude ratio smaller than 0.4 (mean - 2 SD) in the face of a normal side-to-side latency difference is probably abnormal.

Two groups of workers performing office work and light production work were studied. A muscle coordination test with continuous movement of the arm and hand between three target areas and a psychogenic tension test, posing mental demands and with minimal requirement for body movements, aimed to quantify muscle activity in excess of that needed for biomechanical purposes. The electromyogram (EMG) recording of the active trapezius muscle in the muscle coordination test correlated with the median and static EMG values of the vocational (i.e. during the normal work task) trapezius recording both for the office and production workers. but showed no correlation with shoulder-neck complaints. The EMG responses in the psychogenic tension test and of the passive (contralateral) trapezius in the muscle coordination test correlated best with the parameters showing short, spontaneous pauses in the EMG recording of occupational load. For the office workers, but not for the production workers these parameters also correlated with shoulder-neck complaints and the presence of psychosocial problems. Psychomotor tests may thus be useful as indicators of the risk of shoulder-neck complaints in certain occupations, but further experimentation is needed to validate this conclusion.

Twenty-five female subjects were tested at four resistance levels: nominal resistance, and 30%, 50%, and 70% of maximum isometric extension strength. Peak truncal velocity, acceleration, and deceleration decreased with increased resistance, although no difference existed between the nominal and 30% maximum voluntary contraction (MVC) conditions. Coactivation of abdominal muscles was present at all resistance levels, although it was greater for the nominal resistance condition than the other conditions. The timing of EMG activity of the extensor and abdominal muscles was significantly affected by resistance. The amplitude and time course of peak muscle activity are discussed in terms of the implications for spinal loading.

Methods of recording and analysing ES2 have varied between centers and reproducibility of results within subjects, although insufficiently studied, has generally been poor. ES2 was investigated in 30 healthy subjects, using a computerized technique of recording, rectifying and averaging the EMG signals. Hour to hour and week to week variations of ES2 durations were calculated, and the influence of pain during a cold pressor test and of sustained muscle contraction on ES2 durations was investigated. The intra-individual variation of ES2 durations was 16.0% from hour to hour and 20.7% from week to week. The inter-individual variation was 36.7%. The present method for analysis of ES2 periods proved to be reliable, as the intra-observer variation was 4.25% and the inter-observer variation 4.6%. ES2 periods were significantly shorter on the first compared to the second day of examination (p = 0.006) and during experimental pain (p = 0.0005). We recommend the use of the computerized averaging technique in future studies and caution against the dependence of results upon factors such as conditioning and pain.

The myoelectric signals of the multifidus and iliocostalis lumborum muscles of healthy sedentary women were analyzed with regard to spectral parameters during a constant- force contraction, before and after a 3-month period. Results indicated that for both muscles, estimates of initial median frequency and amplitude had high test/retest reliability, but that the recovery and left-right difference parameters were not stable. Using a confidence interval method, test/retest variation for the fatigue parameter was found to be within the range of variability of potentially underlying metabolic processes.

We surveyed 117 pediatric neurologists and physiatrists regarding their practice patterns in pediatric electrodiagnosis; 84 (72%) responded, of whom 44 (52%) regularly perform electrodiagnosis on children (mean = 85 per year, representing 3,667 examinations per year). Respondents reported extreme behavioral distress (eg, screaming, flailing, requiring additional restraint, or attempting to leave the examination table) in 35% of examinations, most often among 2- to 6-year-olds. Pain medications are never prescribed by 45%, occasionally by 48%, and always by 2%; general anesthesia is never administered by 75%, occasionally by 21%. Only 32% reported that any psychological intervention is routinely offered to enhance child coping. Wide variability was found in physicians' preferences about parental presence, order of examinations, demonstration of procedures, and other aspects of electrodiagnosis.

Five isometric test positions were examined. In 21 of the normal subjects, four positions tested were: quiet standing, half extension from prone lying, full extension from prone with and without resistance. In 10 of the normal subjects and the 8 back pain patients, a standardised, unsupported horizontal position with the upper body over the end of a couch was tested. The AMG and EMG signals were full-wave rectified and integrated (iAMG and iEMG). The variability of recordings during repeated 5-s isometric contractions was assessed by analysis of variance (ANOVA) and the coefficient of variation (CV) was calculated from the ANOVA. Both recording techniques produced the most repeatable results during the unsupported, horizontal hold position. In the normal subjects, CV were, iAMG 5.6%, iEMG 4.9%; and in the patients, iAMG 4.4%, iEMG 2.6%. The CV for the other four isometric test positions ranged from 15.3% to 29.4% for iAMG, and 8% to 15.7% for iEMG. These results demonstrated that a controlled test manoeuvre for examining AMG and EMG of the paraspinal muscles was vital for repeatable recordings. The CV for the standardised, horizontal position were lower than for previously published results. This position therefore would appear to be suitable for physiological studies of AMG and EMG activity of the paraspinal muscles in normal subjects and patients with chronic low back pain.

In terms of the activity of the multifidus muscle, the avoider group displayed spectral changes towards lower frequencies, reduced variability in the density spectrum, and higher values of estimated initial frequencies. Measures of the activity of the iliocostalis lumborum did not contribute in any significant way to these group differences. Based on these findings, and on the available literature concerning the histology and physiology of paraspinal muscles, it is proposed that the observed characteristics of the avoider group may be due to a reduced ratio of slow twitch to fast twitch muscle fibers in the multifidus.

Fourteen patients had unilateral onset that later involved the other extremity in 3 days to 8 months. All patients reported stepwise or steady progression during 2 to 18 months that was documented during serial examinations. In 16 patients, both proximal and distal muscles were involved. Sural nerve biopsy specimens demonstrated multifocal variability in nerve fiber density manifesting as non-random fiber loss between and within fascicles compared with age-matched controls. These findings demonstrate that patients may have a rapidly evolving course of proximal diabetic neuropathy followed by continued progression for many months and emphasize the overlap between proximal diabetic neuropathies of presumed different types. Our cases and others cast doubt on notions supporting two distinct types of proximal diabetic neuropathies represented by the rapid evolution of asymmetric weakness on an ischemic basis, in contrast to a more slowly progressive condition of metabolic pathogenesis.

Ten men and 15 women volunteered for this study, in which several aspects of muscle activity were examined. The first aspect assessed the myoelectric relationships during isometric exertions. There was great variability in this relationships between muscles and between subjects. Further, the myoelectric activity levels (normalized to maximal electrical activity) obtained from nontwist activities were not maximal despite maximal efforts to generate axial torque (e.g., rectus abdominis, maximum voluntary contraction; 22% external oblique, 52%; internal oblique, 55%; latissimus dorsi, 74%; upper erector spinae [T9], 61%; lower erector spinae [L3], 33%). In the second aspect of the study, muscle activity was examined during dynamic axial twist trials conducted at a velocity of 30 and 60degree/s. The latissimus dorsi and external oblique appeared to be strongly involved in the generation of axial torque throughout the twist range and activity in the upper erector spinae displayed a strong link with axial torque and direction of twist, even though they have no mechanical potential to contribute axial torque, suggesting a stabilization role. The third aspect of the study was comprised of the formulation of a model consisting of a three-dimensional pelvis, rib cage, and lumbar vertebrae and driven from kinematic measures of axial twist and muscle electromyograms. The relatively low levels of normalized myoelectric activity during maximal twisting efforts coupled with large levels of agonist-antagonist cocontraction caused the model to severely underpredict measured torques (e.g., 14 Nm predicted for 91 Nm measured). Such dominant coactivity suggests that stabilization of the joints during twisting is far more important to the lumbar spine than production of large levels of axial torque.

These disorders can involve dysfunction in the delicate interrelationship of the skull, mandible, cervical vertebrae, and neuromuscular apparatus and can present as myofacial pain. Electromyographic recordings using surface electrodes were made bilaterally on the masseter, anterior temporalis, and digastric muscles in 641 craniomandibular patients, before and after transcutaneous electrical neural stimulation, at their initial presentation and following the insertion of mandibular orthopedic appliances. In the presenting patient, muscle-resting levels significantly decreased from hyperactive levels with transcutaneous electrical neural stimulation therapy. The creation of a new occlusal position with an orthotic appliance was found to correlate with a significant reduction in otolaryngologic symptoms as well as an increase in maximum muscle activity in function and coordination of muscle groups during mandibular movement. Thus, clinical electromyographic studies are an important aid in the treatment of craniomandibular disorders.

It was the aim of this study to determine the range of variability of elevator muscle EMG, to find experimental methods for improving reproducibility, and to establish evaluation procedures that allow the recognition of treatment-induced effects in the EMG even in the presence of great random variations. For this we measured the voltage/tension relation of the elevator muscles of 42 persons in the range of 20 to 500 N on up to 20 different days under constant experimental conditions. The majority of measurements revealed a non-linear correlation between EMG activity and resulting force, hence second order polynomials proved to be more appropriate than straight lines for representing the activity/tension correlation. Muscle activity was found to vary randomly from day to day within each individual. These fluctuations appeared as varying axis intersections, initial slopes and curvatures which are the determinants of the voltage/tension curves. In ten selected subjects random fluctuations were significantly higher when electrodes were repositioned by palpation of the muscle belly than with the aid of tattoos.

Bipolar surface electrodes were used to record tonic, resting EMG activity for 2 consecutive trials. This protocol was repeated at a second recording session 2 weeks later. A custom-made, plastic template was constructed for each subject during the first visit in order to relocate the electrodes accurately at the second recording session. Correlation coefficients were calculated for each muscle area. Within-session (same day) r values ranged from 0.7620 to 0.8884 for the masseteric area and from 0.8686 to 0.9109 for the anterior temporal area. Across-session (different day) r values ranged from 0.5645 to 0.6503 for the masseteric area and 0.3309 to 0.4844 for the anterior temporal area. The lower correlation between different day recordings could reflect a methodological shortcoming in relocating the electrodes, particularly on the anterior temporal area. The greater variability recorded from the anterior temporal area could also reflect the dynamic role of the temporalis muscle in maintaining the postural rest position of the mandible.

Ten trained female workers, without musculo-skeletal complaints at the time of the recording, performed the work tasks while electromyographic (EMG), recordings were obtained from both upper trapezius muscles. Static muscle activity and periods of between 0.2 and 2 s duration with low muscle activity, EMG gaps, were analysed. Complaints of muscular fatigue, soreness or pain in the neck and shoulders during the last 12 months were recorded. The level of static muscle activity was 1.6 (range 0.4 to 2.5) per cent of maximal voluntary contraction and median number of EMG gaps was 4.8 (range 0.8 to 20) per minute. Workers with previous episodes of complaints (five subjects) had higher levels of static muscle activity and fewer EMG gaps than workers without such episodes (p < 0.05, Wilcoxon 2-sample test, one-tailed). Considerable interindividual variability of muscle activity patterns was found in spite of stereotyped work. No causal relations may be inferred from the correlation between the level of trapezius activity and complaints, though it indicates that individual, inexpedient muscle activity patterns may constitute an important risk factor for development of musculo-skeletal complaints.

Bilateral electromyograms of jaw elevators, and jaw movement, were recorded for three complete masticatory sequences. Computer analysis was used to classify chewing movements as continuous or discontinuous. Root-mean-square (r.m.s.), myoelectric signal amplitudes were computed for each of four jaw elevators. Although discontinuous chewing cycles were significantly more frequent in painful function (p = 0.001), they also occurred in pain-free function, a finding which reduces their diagnostic significance. During painless and painful function, r.m.s. activities did not differ statistically when elevators acted as agonists on both the dominant and non-dominant chewing side (p greater than 0.1). When used as antagonists, such as during jaw opening, the elevators had greater mean peak activities during painful than painless function (p = 0.0001). Variability in maximum gape was greater during painful than painless function (p = 0.001), but peak maximum gapes in complete masticatory sequences were not affected by pain, and neither were minimum interocclusal gapes. More frequent reshaping and repositioning of the bolus in the presence of pain could explain these differences between painful and pain-free function.

Dualsite EMG monitoring was employed during both static postures and movements. Flexion and rotation indices were divided to assess the reliability of patterning of paravertebral EMG during movement. Within-session reliabilities computed for the full sample ranged from 0.66 to 0.97, and between-session reliabilities, computed on a subset of 29 patients retested after varying intervals, ranged from 0.26 to 0.92. Average EMG levels, flexion, and rotation indices showed no statistically significant differences between surgical (n = 40) and nonsurgical patients (n = 30), although EMG variability was consistently greater for surgical patients across the postures and movements. These results indicate that lumbar paravertebral EMG can be reliably measured and therefore has potential utility as an assessment and treatment variable in CLBP.

With a computer-based system, EMG and displacement signals were collected simultaneously during specific functional (unilateral chewing) and parafunctional tasks (mandibular gliding movements and various tooth clenching efforts) and analyzed quantitatively. When a naturally acquired group function was temporarily and artificially changed into a dominant canine guidance, a significant general reduction of elevator muscle activity was observed when subjects exerted full isometric tooth-clenching efforts in a lateral mandibular position. The original muscular coordination pattern (relative contraction from muscle to muscle) remained unaltered during this test. With respect to unilateral chewing, no significant alterations in the activity or coordination of the muscles occurred when an artificial canine guidance was introduced. Introduction of a hyperbalancing occlusal contact caused significant alterations in muscle activity and coordination during maximal tooth clenching in a lateral mandibular position. A marked shift of temporal muscle EMG activity toward the side of the interference and unchanged bilateral activity of the two masseter muscles were observed. The results suggest that canine-protected occlusions do not significantly alter muscle activity during mastication but significantly reduce muscle activity during parafunctional clenching. They also suggest that non-working side contacts dramatically alter the distribution of muscle activity during parafunctional clenching, and that this redistribution may affect the nature of reaction forces at the temporomandibular joints.

The treatment program consisted of progressive relaxation, EMG-biofeedback and cognitive methods. At the end of the treatment, as well as at a 6 months follow-up, the patients reported a marked decrease in headache intensity and duration. A qualitative analysis was performed with patients who did not show progress and with dropouts. It revealed several variables which could have impeded behavior change such as the variability of headache intensity, positive consequences of pain behavior, the attribution of pain to illness, frequenting general practitioners, medical specialists and paramedics, the expected negative consequences of re-employment, the investment in the treatment and activities towards self-management.

Many patients undergoing this training are concurrently taking propranolol, a beta blocker, and/or amitriptyline, a tricyclic antidepressant which inhibits re-uptake of serotonin. There is an extreme paucity of information delineating the effects and interactions of these medications in patients learning autonomically mediated vascular control through biofeedback. In this pilot study we examined the ability of patients to learn vascular control and neuromuscular control. Four groups of patients were used: those taking no medication, those taking propranolol or amitriptyline alone, and patients using both medications. Results indicate the use of propranolol in patients learning vascular control produces a markedly increased variability in the ability of patients to control physiological parameters; this difficulty is also manifested in EMG training of patients taking only amitriptyline. Those within group variances were found to be negated by the use of both medications together. In spite of these findings, all groups did reach training criterion. In some patients the inability to easily control baseline physiological parameters may induce enough frustration to cause premature termination of training. It is postulated that the effectiveness of biofeedback training might be enhanced in patients not concurrently taking medications with autonomic effects.

Fifty-nine outpatients with a variety of chronic pain problems, who had completed at least six biofeedback training sessions, were sorted into three groups according to their medication status: No medication; light medication, defined as antipyretic/anti-inflammatory agents; heavy medication, defined as highly active CNS-ANS substances (primarily tricyclic antidepressants). Analyses of the session-by-session physiological indicators revealed that the heavymedication compared to the no-medication patient had consistently lower baseline EMG and SCL, although these baseline differences were reduced considerably by the final session. The ligh-medication group fell between the extremes. During biofeedback the drug-group EMG differences were minimal, although the relative SCL differences were maintained. Significant group TEMP differences were precluded by a high degree of individual variability. In general, sedation effects of heavy medication were apparent in the results and, as predicted from the law of initial values, unmedicated patients demonstrated larger changes during biofeedback training. However, the present design does not permit a test of whether the unmedicated patients achieve greater generalization and long-term maintenance of physiological self-regulation. It was encouraging that several medicated patients tested in unmedicated states at a later date demonstrated little loss of performance.

Earlier treatment with medication and neurosurgery had not been successful. The authors used electromyography to examine the disturbed muscle function and to investigate a possible cause for the pain in the muscles of mastication. The silent periods of the patient's muscles were measured before and after treatment, since it is known from the literature that the EMG silent periods may be elongated in patients with TMJ dysfunction or occlusal irregularities. The coordination of both heads of this patient's lateral pterygoid muscles were bilaterally investigated before and after treatment. Treatment consisted of splint therapy and selective grinding. Oral rehabilitation was also undertaken, beginning three months after the disappearance of the patient's symptoms.

The research has shown the clicking TMJ is sometimes helped but not cured by the traditional stabilization interocclusal appliance and that TMJ clicking is the least responsive to treatment. Questions have been raised about the need to specifically treat the clicking joint; more research on this issue is necessary. Painful TMJs have been shown to respond to occlusal appliance therapy, but questions still exist about the effectiveness of interocclusal appliances for this symptom. There is little scientific proof available about the ability of splints to effectively slow down or reverse degenerative TMJ changes that are evident on radiographs. Masticatory muscle pain is by far the symptom that has the best experimental evidence to support occlusal splints as a highly effective method of treatment. These changes are probably mediated via an alteration in the patient's muscle activity patterns. Those patients with more severe symptoms are less likely to be helped with splints as a sole treatment modality. The effect of occlusal appliances in muscle trismus has been discussed but not effectively evaluated in the literature. Occlusal splints have been shown to have a distinct influence on improving mandibular muscle coordination. Inter-occlusal splints are a commonly used method of controlling attrition and adverse tooth loading, and few questions have been raised in the literature about this therapeutic application.

As compared to controls, patients before treatment chewed with greater relative strength (percent of maximal elevator activity), longer relative contraction times (percent of total duration of chewing cycle) and stronger intermediary activity between strokes. These parameters of muscle coordination are proposed as quantitative estimates of "hyperactivity". Conventional treatment abolished pain, tenderness and other symptoms and signs completely in 18 patients in whom the most significant findings in the muscles under study were reductions in absolute and relative contraction times ascribed to increased stability produced by occlusal adjustment. It is suggested that relatively shorter pauses before treatment impaired blood flow and that their prolongation following treatment improved circulation. During the strong, dynamic contractions of mastication, masseter muscles tended to be more susceptible to hyperactivity than the temporal muscles.

The specific relationship between temporal artery activity and anxiety and temporal artery activity and pain was also determined. The results indicated the presence of an increased variability in the right temporal artery three days preceding the migraine with the absence of changes in the general autonomic and skeletal muscle measures. Considerable individual differences in temporal artery amplitude were observed necessitating an analysis of individual patients which revealed a general pattern of dilation three days prior to the attack and constriction the day preceding the attack. Increased anxiety was noted only on the headache day. Elevations in anxiety four days prior to the migraine were associated with the increased temporal artery variability observed three days prior to the attack. Anxiety experienced on the headache day was not related to changes in temporal artery amplitude variability or pain. Temporal artery dilation was not consistently associated with the site of pain. The results provide support for a disregulation theory of migraine relating anxiety to temporal artery change across days preceding the attack but question major assumptions regarding anxiety, temporal artery activity and pain during the headache itself.

This paper reviews the evidence for this belief and describes the results of a study of muscular activity over a prolonged period by means of a portable battery powered electromyographic recording apparatus. In earlier studies of nocturnal masseter muscle activity ther was found a correlation between nocturnal bruxism and reports of stress. More recent studies covering activity for 24 hours per day have suggested that periods of muscle hyperactivity are correlated with specific daily activities but that there is great variability between patients. It is not yet possible to determine whether the patient's report of anxiety is the result or the cause of the orofacial muscular pain problem. It is evident that other parameters require evaluation.
