Development of a simulation model for walking of human with hip disarticulation prosthesis using neuro-musculo-skeletal model

Abstract

This paper describes the development of a model which simulates the walking with a hip disarticulation prosthesis (HDP). In order to characterize walking with an HDP, the motion analyses were performed and incorporated into this study. Results of these analyses suggested that a three-dimensional model of the entire body was necessary to generate an accurate walking with an HDP. Therefore, a three-dimensional neuro-musculo-skeletal model of a human wearing an HDP was proposed including the mechanical model of an HDP and a neural model of a hip disarticulation amputee. After 20,000 iteration computation for the optimization process of neural parameters, simulated walking qualitatively represents the measured characteristics and dynamics of walking with an HDP.
