Values were obtained performing video analysis at 20-wk of the healing period. Results are presented as mean and standard deviation (SD) (n = 7). For each step cycle the following time points were identified: Initial contact (IC), opposite toe off (OT), heel rise (HR) and toe-off (TO). PVA: Polyvinyl alcohol; CNTs: Carbon nanotubes; PPy: Polypyrrole.
