Fig. 2From: Mechanics and energetics of post-stroke walking aided by a powered ankle exoskeleton with speed-adaptive myoelectric controlPeak paretic ankle power increased with walking speed and with exoskeleton assistance. Group average time-varying paretic ankle power in the Unassisted condition (a) and the Assisted condition (b), with the exoskeleton contribution isolated (c). Walking speed was increased from 60% of the users’ comfortable OVG speed (OVG) by 0.1 ms−1 each minuteBack to article page
