Since many years, numerous skeletal muscle models have been proposed to express the relationship between muscle activation and generated force. One of them (Makssoud et al [2]-[3]), integrates the Hill model [5] and the physiological one based on Huxley work [4] allowing the muscle activation under FES. We propose in this paper an improvement of this model by modifying the activation part. These improvements are highlighted through the HuMAnS toolbox [1] using a 3D biomechanical model of human named Human 36. This article describes this toolbox and the software implementation of the model. Then, we present the results of the simulation.
