Orthosis for the Hand and Arm: This is MyoPro®
MyoPro® is a powered orthosis for the hand and arm designed to restore function in a paralyzed or weakened arm and hand. For example, after a stroke, the MyoPro® orthosis supports users in performing everyday movements despite existing paralysis—movements that would otherwise be difficult, impossible, or not feasible with both hands.
How does MyoPro® work?
MyoPro® works by detecting muscle signals from the surface of the skin. These signals activate the orthosis’s powerful motors, enabling the hand and arm to move as intended. Full control remains with the user—the MyoPro® system simply amplifies weak muscle signals to make movement of the elbow and hand possible.
This process requires no implants, making the orthosis non-invasive and eliminating the need for electrical stimulation. In essence, it functions like a “power steering system for your arm.”
While many prosthetic solutions exist for people who have lost limbs, and orthopedic devices support weakened legs, MyoPro® is the first wearable robotic orthosis system designed to restore function for individuals who still have their arms and hands but are unable to use them. It can be used, for example, after a stroke or other neurological conditions affecting arm function.
The MyoPro® arm and hand orthosis was originally developed at the Massachusetts Institute of Technology (MIT) in collaboration with Harvard Medical School.
