Simulating the human motion under functional electrical stimulation using the humans toolbox

Abstract

Mathematical models of the skeletal muscle can support the development of neuroprostheses to restore functional movements in individuals with motor deficiencies by means of XE Functional electrical stimulationFunctional electrical stimulation (XE FESFES See Functional electrical stimulation). 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.), integrates the Hill model and the physiological one based on Huxley work allowing the muscle activation under FES. We propose in this chapter an improvement of this model by modifying the activation part. These improvements are highlighted through the HuMAnS (Humanoid Motion Analysis and Simulation) toolbox using a 3D biomechanical model of human named Human 36. This chapter describes this toolbox and the software implementation of the model. Then, we present the results of the simulation. © 2009 Springer-Verlag London.
