Hip angle, torque, and power measured during the 10mWTs with the APO in assistive mode. (a) The hip angle measured by APO encoders, the APO hip torque and power normalized to body mass. The angle, torque, and power profiles are shown for each participant; each profile is depicted by the average (solid line) and standard deviation (shadow area) over all the strides of the 10mWT in AM. (b) APO energy injected during the entire stride duration, normalized to body mass. All bar plots represent means and standard deviations computed over all the strides of the 10mWTs in AM for each participant. On the right, the averaged values across participants (Avg) for paretic (grey) and nonparetic side (black), that resulted statistically different (paired-ttest, p < 0.05).
