Abstract : Under spinal cord injury, the natural control of limbs becomes impossible, which leads to partial or totale paralysis. Functional Electrical Stimulation (FES) may then be used to substitute the central nervous system by contracting the skeletal muscles for mouvement rehabilitation of paralysed muscle-limb. In addition, FES presents many therapeutic benets for SCI patients. However, its application poses some problems in practice. Indeed, the applied stimulation patterns are always empirically tuned, increasing the muscular fatigue and limiting the use to short periods of time. Thus, an accurate numerical model of the muscle-limb dynamics is needed which involve an experimental parameters identication procedure. The main contributions of this thesis are 1) A parameters identication set up of a musculoskeletal physiological model in spinal cord injured subjects and 2) Synthesis of functional electrical stimulation patterns based on the identied model.
