Myoelectric Hands

–  Electronic prosthesis:

Depends on the work on electronic electrodes over the muscles, contraction of the muscles stimulates these electrodes to send an electric signal to open or close the electronic hand.

These prosthesis are expensive compared to the cosmetic and mechanical prosthesis, but cannot be used immediately after the amputation, as the patient must be used on traditional prosthesis and got the appropriate atrophy in stump and obtained the strength of the muscles before moving to electronic prosthesis. Its function is only to open and close the hand as in the mechanical prosthesis but with an easier and more receptive system for the amputee.
