The MyoPro, an upper extremity limb orthosis, is an assistive device that supports a weakened or deformed limb for functional improvement. The user’s electromyography (EMG) muscle activity is used to voluntarily control the impaired limb.The MyoPro consists of a combination of the following components: a shoulder harness, a custom-made upper limb orthosis (brace), a powered elbow orthosis with surface electromyography (EMG) sensors, a static or manually set multi-articulating wrist (MAW), a static hand orthosis or powered hand orthosis with EMG sensors, and an interchangeable battery with a separate recharging station.The MyoPro’s EMG-control circuit continuously monitors and senses, but does not stimulate, the User’s muscles. The MyoPro filters and processes the EMG signal, and translates this information into motor movement. Based on the User’s needs and abilities, the control parameters are adjusted by the User’s Provider. The power assist moves the motor with speed proportional to User’s exertion. This system enables the MyoPro to assist the User to initiateand complete desired motions.
An externally applied orthopaedic appliance or apparatus designed to encompass the elbow joint, the wrist joint, and the whole or part of the hand to support, align, prevent, or correct deformities/injuries or to improve function of the elbow, wrist, and hand. This is a reusable device.
