Lower-limb kinematics during treadmill walking with and without the APO. a, b) Hip, knee and ankle angle profiles of the paretic (a) and nonparetic limbs (b) during treadmill walking in the following conditions: (i) walking without the APO (NoAPO, grey), (ii) walking with the APO in assistive mode (AM, blue), (iii) walking with the APO in transparent mode (TM, bordeaux). Aggregated profiles across participants are shown as mean (solid line) ± s.e.m. (shadow area). c) Sagittal range of motion (ROM) of the hip, knee, and ankle joints of the paretic (left) and nonparetic (right) side. Aggregated data are reported in bar plots as mean ± s.e.m (n = 6) for the different walking conditions (NoAPO, AM, TM). Colored dots represent individual study participants. The percentage changes in AM with respect to NoAPO and TM are indicated above the bar plots. The asterix indicate the statistically significant differences when comparing APO in AM versus NoAPObaseline (post-hoc test p < 0.05).
