From: A biomechanical cause of low power production during FES cycling of subjects with SCI
Joint muscle moments and power produced by the right leg of a representative subject with SCI pedaling at 60Â rpm with stimulation of quadriceps and hamstrings to produce 15Â W. Panel A and B: The hip and knee joint moment patterns. Panel C: the knee (dashed), hip (dashed-dotted) and net power (continuous) are shown. The power components P1-P3 are marked in Panel C to represent the different contributions to the net power. Phase advance corrected stimulation intensities (on-off step-functions) for quadriceps (thin black dotted) and hamstrings stimulation (thin grey dotted) are shown.
