Abstract: Apparatus and methods of rotating a non-functioning or injured wrist by flexing or extending the associated elbow may be activated by muscle action of the wearer or by an elbow actuator. Cuffs disposed above and below the elbow that receive the wrist and arm are interlinked in a manner that permits varying of the degree of supination and pronation of the wrist to the needs of the wearer. Also, the angle of elbow flexion at which wrist rotation starts and stops can be varied by adjusting the operating mechanism.

Abstract: A therapeutic electronic range of motion apparatus includes a remote subsystem for generating motion commands which are transmitted to a local subsystem at an orthosis, prosthesis or CPM machine. The local subsystem includes a local controller for controlling and monitoring the position, speed, and direction of an actuator which moves an orthotic brace, prosthesis or CPM machine mounting. The apparatus is programmable enabling a patient to program stopping positions which thereafter are selectable by command. When the actuator is not in motion the local controller enters a sleep mode to conserve power. The controller is automatically awakened when a motion command is received.
