Biomechanical Model of the Hand for Upper Limb Prosthesis Evaluation

Abstract

Prosthetic hands provide amputees with the chance to recover their lost abilities, however, there is no comparison made between the movement of a prosthetic hand versus a biological hand. This project aims to create a biomechanical model that describes the variation and similarity between the kinematics of a biological hand and a prosthetic hand. This project utilizes motion capture through a specific active marker infrared assembly to obtain the kinematic analysis of both prosthetic and biological hands. The results obtained showed a substantial difference between the flexion angles between the biological hand and the prosthetic hand in the distal phalange joints.
