Myoelectric prostheses aim to restore the functionality of amputated limbs and improve the quality of life of amputees. Myoelectric training systems are used to train and assess the ability of amputees in how to use myoelectric technology in advance of receiving their actual myoelectric prostheses. This article describes the myoelectric training systems that have been developed over the last 20 years in both the literature and commercial industries. The results of this article will identify common features in the training systems and suggest areas for future improvement.
