Abstract: A hand held upper extremity rehabilitation and exercise device comprising two interconnecting pieces in the shape of a dowel or rectangle of which contains corresponding apertures in graded dimensions receiving corresponding graded flexible tubing ends in and through the device and where one piece slides distally upon a static piece decreasing the aperture space and subsequently initiating 3 point contact of the tubings within the device when tension of the tubings are increased through exercise and range of motion by the user. The device utilizes the principle inherent to elastic compression where the resistance of the tubing during exercise exerts the force of same upon the perimeters of the sliding part moving the piece distally parallel to the line of pull resulting in 3 point contact within the device where compression is always greater than the disconnecting force without the device.

Abstract: A hand rehabilitation device including a circular planar disk having a series of spread-apart recesses in its circumference receives the fingers of a patient's hand with the thumb inserted through a selected one of a plurality of apertures. The joint of the finger extending across the disk may be active or passively exercised while the patient holds the disk.
