Fig. 5

Between-group comparisons of angular velocities (pitch, yaw, roll) and linear accelerations (vertical, antero-posterior, lateral) of the (A) ipsi-lesional ankle, and (B) dominant wrist during all 10 tasks of the Functional Gait Assessment (FGA) scale. Blue asterisks indicate statistically significant differences with greater values for the healthy control group, and red asterisks indicate statistically significant differences with greater values for the SCDS group. Ipsi-lesional ankle: Denotes the symptomatic side for SCDS group, and right side for control group. Light blue columns are range of pitch velocity and variability of pitch velocity; light yellow columns are range of vertical acceleration and variability of vertical acceleration. Red boxes highlight the gait tasks consistently showing a reduced range of vertical acceleration in the SCDS group. The corresponding numerical values (mean ± SD) of each kinematic measure for both healthy control and SCDS groups have been presented in Supplementary Tables 4–6. (C) Between-group differences of the mean, standard deviation (SD), and coefficient of variation (CV) of the gait cycle durations, and time and step length asymmetries during each task of the FGA scale. The corresponding numerical values (mean ± SD) for both healthy control and SCDS groups have been presented in Supplementary Table 7. *p < 0.05, **p < 0.01, and ***p < 0.001. ^a: Wrist IMU data was available for 16 individuals with SCDS and 15 healthy controls.
