Feasibility of a hybrid-FES system for gait restoration in paraplegics

This paper proposes a new configuration for a hybrid-FES gait restoration system, and presents a combination of simulation and experiment that support the feasibility of the proposed approach. Gait simulation results are presented that indicate the majority of load bearing and the majority of power for gait is provided by the legs (i.e., quadriceps muscle stimulation). Based on these simulations, experiments on healthy subjects indicate that the gait restoration approach should be capable of providing long periods of locomotion unimpeded by quadriceps muscle fatigue.
