A Preliminary Study of Task Assessment Methods for Upper Limb Myoelectric Prostheses

Abstract

To address the problem of limited functional assessment of the wrist and hand of myoelectric prostheses leading to poor rehabilitation outcomes, this paper proposes a multivariate assessment method and builds a prosthetic assessment platform. On this basis, five healthy subjects and two amputees were recruited to carry out the corresponding evaluation experiments for validation. The results of the healthy subjects were better than those of the amputees, and there were significant differences in critical performance between the prosthetic and standard hands, with a higher level of shoulder compensation in the prosthetic subjects than in the healthy subjects. The results suggest that the platform and method can provide more information than traditional assessment, thus helping rehabilitation practitioners understand prostheses in amputees and provide individualized training programs.
