A Novel Myoelectric Training Device for Upper Limb Prostheses

A training system intended for myoelectric prosthetic hands for upper limb amputees was developed to assist in learning myoelectric control schemes and training muscle isolation. The trainer allowed a user to operate a remote controlled car by use of a control scheme commonly used in myoelectric prosthetic hands. The trainer was designed to be easy for therapists to use and more engaging for the user than current methods of signal training. Preliminary testing of the trainer was conducted with eight nonamputee adult volunteers. The results indicated that the trainer could be a useful tool for myoelectric training in upper limb amputees. All subjects´ skill with the myoelectric control scheme improved over the course of testing, with the improvements being greater at the beginning of the training period than at the end. Whereas the individual subjects´ performance varied greatly at the beginning of the training, the subjects had achieved a more uniform level of performance by the end of the training, approaching the minimum possible values for the assessments.
