Abstract

A 10 link, 14 degree-of-freedom musculoskeletal model of the lower limbs has been developed for FES-aided gait applications. The purpose of the model is to facilitate the design of controllers which will maximize the performance of artificial gait systems. To determine the utility of such models in practical situations, it is necessary to verify their accuracy. Experiments were performed to determine whether a subset of the full model could predict motions and forces in actual limbs. Able-bodied were suspended with two legs dangling. Knee and hip joint angles were measured in response to passive initial condition releases and to activation of single muscles by electrical stimulation. Parameters of the model were customized to individual subjects.
