Fatigue and Muscle Strength Involving Walking Speed in Parkinson’s Disease: Insights for Developing Rehabilitation Strategy for PD

Figure 1

Representative force-time curves of MVC, twitch force, and interpolated twitch for one PD patient ((a)–(d)) and one healthy subject ((e)–(h)) before (pre) and after (post) fatigue. The -axis shows the percentage of the peak MVC, with the prefatigue maximum set to 100%. : potentiated twitch was also used to represent twitch force.
