Designing a Virtual Reality Myoelectric Prosthesis Training System for Amputees

Electrical signals produced by muscle contractions are found to be effective in controlling accurately artificial limbs. Myoelectric-powered can be more functional and advantageous compared to passive or body-powered prostheses, however extensive training is required to take full advantage of the myoelectric prosthesis' usability. In recent years, computer technology has brought new opportunities for improving patients' training, resulting in more usable and functional solutions. Virtual Reality (VR) is a representative example of this type of technology. These preliminary findings suggested that myoelectric-powered training enhanced with VR can simulate a pain-free, natural, enjoyable, and realistic experience for the patient. It was also suggested that VR can complement prosthesis training, by improving the functionality of the missing body part. Finally, it was shown that VR can resolve one of the most common challenges for a new prosthesis user, which is to accept the fitting of the prosthetic device to their own body.
