From: A neuromechanics-based powered ankle exoskeleton to assist walking post-stroke: a feasibility study
Whole-body net metabolic power (averaged over 5 subjects). Whole-body net metabolic power (W kg-1) across conditions of NoEXO (black), UnPOW (red), and three repetitions of POW (blue) were analyzed. Although there was no statistically significant effect of the exoskeleton on net metabolic power (p = 0.21), there was a tendency for a gradual reduction of metabolic cost with each bout of the powered walking conditions. The percent change values are expressed relative to the NoEXO condition. The error bars represent ± 1.0 standard deviation.
