Project Title:
Technologies to Train Myoelectric Prosthesis Users for Optimal Functional Outcomes

Functional, effective training is key to a patient’s success using a myoelectric prosthesis. The critical time for developing good myoelectric control habits is in the pre-prosthetic phase (between wound healing and prosthesis delivery) but should continue after prosthesis delivery as well. Current myo-training devices rely on technologies that are expensive, manufacturer specific, and are typically non-motivating.

LTI is creating a portable, affordable, and interactive myoelectric training system that can be used in the clinic or home. The myoelectric gaming interface (MEGI) maps signals typically used for prosthesis controls to video games for training. The system leverages existing video game software with a focus on clinically relevant exercises. This device will likely increase the ease of myoelectric training and help lead to improved functional outcomes for the patient and cost savings for the healthcare provider.

LTI is investigating the long-term effects of myo-training on prosthesis control and outcomes. The aim of the project is to provide patients with a more engaging way to train for prosthesis use.
