From: A neuromechanics-based powered ankle exoskeleton to assist walking post-stroke: a feasibility study
Paretic ankle positive work (averaged over 5 subjects). The paretic ankle joint positive work (J kg−1) across conditions of NoEXO (black), UnPOW (red), and three repetitions of POW (blue) were analyzed from the last minute of each condition. The exoskeleton’s contributions to the total positive work during POW are denoted in white. There was no statistically significant effect of the exoskeleton on the paretic ankle joint positive work (p =0.58). The error bars represent ± 1.0 standard deviation.
