ABSTRACT:
A device for handgripping or squeezing, forearm twisting, wrist casting, wrist rocking and a combination of some of these. A handle mechanism is rotatably mounted on a frame. This mechanism includes a fixed handle and a movable handle, movement of the last mentioned handle being resisted by a force which may be varied. One may grasp the two handles simultaneously and exert the fingers so as to move the movable handle towards the fixed handle in opposition to the applied force. Rotation of the handle mechanism is provided with torsional resistance which may be varied. One may grasp the fixed handle with the arm in alignment with the axis of the device and rotate the handle mechanism in either direction or one may grasp the fixed handle with the arm disposed at right angles to the position previously described and rotate the handle mechanism in either direction. A third handle may be provided which is disposed at right angles to the fixed handle, in alignment with the axis of the device and which may be grasped by the user so as again to rock the handle mechanism in either direction. Squeezing resistance may be effected through a cable attached to the movable handle and to an extension spring. Torsional resistance may be effected between a rotatable friction disk and a slidable, but not rotatable, friction disk which may be forced against the rotatable friction disk by a force which may be varied.
