ABSTRACT:
A continuous motion device for the therapy and rehabilitation of a patient's hand and fingers comprises a splint adapted to be mounted to the patient's forearm and hand, a gear housing rotatably mounted around a reversible motor, with the reversible motor driving a gear mechanism provided in the gear housing. The gear mechanism driving a digit attachment member in a rotational movement therewith. When actuated, the reversible motor causes the gear housing to rotate about the axis of the motor with the digit attachment member counter-rotating relative to the gear housing about another axis spaced apart from and parallel to the motor axis, whereby the absolute motion of the digit attachment member and therefore of the patient's fingers follow a compound spiral. The compound spiral, depending on the ratios of the gears of the gear mechanism, can follow one of a series of multiple lobed compound spirals, having open or closed loops. The range of motion of the digit attachment member and the speed thereof can be adjusted. Various motions can thus be imparted to the fingers of the patient.
