Fig. 3From: Effects of overground gait training assisted by a wearable exoskeleton in patients with Parkinson’s diseaseLeft hip angle profiles for patient #1 in the three evaluation sessions, with flexion (resp. extension) angles indicated by positive (resp. negative) values. Signals were time-normalized over the gait cycle. Solid lines represent the mean and shaded areas represent the standard deviation over all gait cyclesBack to article page
