Fig. 3From: Standardizing fatigue-resistance testing during electrical stimulation of paralysed human quadriceps muscles, a practical approachRelationship between torque and knee-extension-angle. The data displayed illustrates the relation between peak-torque and knee-extension angle (mean of each electrode configuration). Data was normalized to the individual maximal peak torque for each electrode configuration. For a better readability, SD is not shown in the diagramBack to article page
