The MyoPro 2x, 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 2x 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 wrist module, a static hand orthosis or powered hand orthosis with EMG sensors, and an interchangeable battery with a separate recharging station. The MyoPro 2x EMG-control circuit continuously monitors and senses, but does not stimulate, the User’s muscles. The MyoPro 2x 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 2x to assist the User to initiate and complete desired motions.
A computerized device assembly designed for analysis and real-time feedback (biofeedback) of a variety of physiological parameters [e.g., heart rate, respiration, skin conductance, skin temperature, range of motion, force output, electroencephalography (EEG), electromyography (EMG), electrocardiography (ECG) data] to assist a patient in developing a degree of conscious control over typically involuntary functions, usually for relaxation training and muscle re-education. It includes multiple pieces of patient monitoring hardware (e.g., electrodes, sensors), computer interface devices, and dedicated software; it is intended to be used with an off-the-shelf computer.
