Muscle Fatigue Study in FES-induced Dynamic Cycling Movement

摘要

The muscle fatigue characteristics was studied from biomechanical modelling analysis and stimulus EMG measurement during FES-induced cycling movement. Inverse dynamics method was used to calculate the knee joint torque which represents the muscle force generated during cycling movement. The peak-to-peak of stimulus EMG, after suppression of stimulus artifact, was adopted as fatigue indicator during dynamic movement. Our observations from stimulus EMG and inverse dynamics indicate that the paralyzed muscles might not reach complete fatigue when the cycling movement cannot continue.
