Patented EMG (electromyography) control software continuously monitors and senses, but does not stimulate, the affected muscles. The user self initiates and achieves natural movement patterns by their own muscular signals that indicate intention to move. The system senses even a very weak EMG muscle signal and then processes data to a motor on the device that enables desired motion. This processing occurs so quickly that it is not apparent to the patient. Importantly, the EMG-driven device requires that users are actively engaged throughout the movement; if they stop, the device stops. No electrical stimulation or invasive procedures are employed.
By supporting the research into Myoelectric technology in 1990†, the Veterans
Administration promoted and inspired development for a future myoelectric
orthosis that could be of benefit to Veterans that have upper
extremity impairment. Today, Myomo is assisting Veterans with MyoPro.
