The MyoPro® is designed to enable individuals to support and assist movement of a weak or deformed hand and arm. Patients can self-initiate and control movement of a partially paretic upper limb using their own myoelectric signals. Similar to how a myoelectrically controlled prosthetic operates, the MyoPro orthosis utilizes surface EMG sensing technology to enable volitional motion of the impaired limb. When the user tries to move their extremity, sensors in the orthosis detect, process, and amplify the weak myoelectric signal, which activates motors to move the extremity in the desired direction. The user is in complete control of their own extremity; the orthosis assists with movement only once a signal is detected.
The MyoPro orthosis enables individuals with paretic arms to better perform functional tasks of daily living, including feeding, reaching, and lifting.
