Sensor location and axes orientation of the Magneto-Inertial Measurement Units (MIMUs) attached on the children’s body segments.
H: head level; S: sternum level; P: pelvis.
Table 1.
Gait parameters obtained for both the TD and CP groups.
Table 2.
RMS accelerations and attenuation coefficients in the TD and CP groups.
Fig 2.
On the left, RMS of the acceleration components at the three levels.
On the right, attenuation coefficients from pelvis to head (CPH), from pelvis to sternum (CPS), and from sternum to head (CSH) along the three anatomical axes. Parameters computed for the TD and CP groups are represented with empty and filled box-plots, respectively. Significant between-groups differences (p < 0.05 or p < 0.01) are reported with the symbol § or §§, respectively.
Fig 3.
RMSa inter-component relationships for the two groups (TD in light grey and CP in black).
The inter-component comparison graphs characterized by significant different regression lines between the TD and CP groups are reported in figure: RMSaAP vs RMSaML for head (p = 0.007), RMSaML vs RMSaCC for sternum (p = 0.048), and RMSaAP vs RMSaCC for pelvis (p = 0.043).
