ABSTRACT:
A device for providing continuous passive motion therapy to a patient's wrist comprises a base removably attached to the forearm of the patient rearwards of the wrist. The base includes horizontal turntable which can be secured thereon in a selected position. A wheel driven by a motor is rotatably mounted on the turntable for rotation in a vertical plane. A telescopic motion transmission which is provided between the wheel and a handle is mounted eccentrically to an eccentric disk which in turn is eccentrically and parallely mounted on the wheel. The eccentric disk may be rotated relative to the wheel to vary the absolute eccentricity of the motion transmission with respect to the rotation axis of the wheel. The handle which is universally mounted to the motion transmission includes a grip. Therefore, a rotation of the wheel and thus of the eccentric disk caused the motion transmission to pivot and to impart to the patient's hand a preselected pivoting motion about the wrist being treated. The present invention can also be adapted to other joints, such as ankles.
