Biomechanical models of computerized prosthetic leg

Abstract

Computer-controlled prosthetic devices are becoming more popular among people of all ages from all over the world suffer amputations. Only 5% of them in need have access to assistive products. This paper presents an analysis and an assessment of biomechanics of physiological gait and the construction of prosthetic leg. The normal gait patterns are performed to develop dynamic biomechanical models of the computerized prosthetic leg for productive simulation of a transfemoral amputee’s gait under different conditions. The purposes of the current research project are to provide and modify biomechanical models for a better understanding of amputee gait and make changes on prosthetic leg components for improving the ambulatory performance. Three-dimensional finite element analysis and Solidworks Simulation are used to investigate kinetic and kinematic characteristics of gait in patients with limb loss. Findings from the current study reveal that most people with lower limb amputations prefer computerized prosthetic leg to passive prosthetic leg.
