Typical therapy setting, reproduced by employees of the institute. The subject is wearing wests and belts to apply the electric stimulation and is supervised by a trained physiotherapist.

Mean values of NSCBP-patients (at T0) and the subjects with “healthy back”.

The flow of participants throughout the study.
NSCBP = nonspecific chronic back pain; n = number of subjects in subgroup; EMS = WB-EMS-Group; ACG = active control group.
Table 2.
Mean values and changes of the WB-EMS group.
Fig 3.
The 4 variables with the highest relative improvement in WB-EMS group.
Mean values (columns) and standard deviation (black lines) of outcome scales Oswestry Disability Index (ODI), Numeric Rating Scale (NRS) and the subscales of the short form 36 (SF36). ACG = active control group. EMS = WB-EMS group, healthy = subjects without back pain.
Fig 4.
The 4 variables with the highest relative improvement in ACG.
Mean values (columns) and standard deviation (black lines) of outcome scales Trunk rise test: relative total maximal force (F totmax rel) in N/kg, Chair Rising Test: time per repletion in seconds, Stair Climb Test: average relative power (average Pwr rel) in W/kg and average power (average Pwr). ACG = active control group. EMS = WB-EMS group, healthy = subjects without back pain.
