Fig. 6From: Toward a hybrid exoskeleton for crouch gait in children with cerebral palsy: neuromuscular electrical stimulation for improved knee extensionKnee angle profiles averaged for each gait cycle during all four walking conditions in a left leg and b right leg. Average profile over all gait cycles shown in bold for each condition with transparent spread representing ±1 standard deviation. Black bars along horizontal axes show the average gait cycle duration ±1 standard deviation when electrical stimulation was administered in each limb. The average knee angle profile of a healthy gait pattern from a previous study [20] is shown in grey for referenceBack to article page
