Modeling Fatigue Effect in an EMG-Driven Hill Type Muscle Model during Dynamic Contractions

Since appearance of fatigue is a reality in rehabilitation sessions, developing a muscle model that is able to cope with this effect in dynamic contractions is a must. In this paper we attempt to model the effect of fatigue in a Hill type muscle model with weighting sum of joint torques. Focus on an upper limb movement to evaluate the model, specifically an elbow flexion-extension, the promising results will contribute to achieve a generalized model that is able to mold to different movement conditions.
