ABSTRACT:
The present invention relates to a user force application device which will optimally be used with a computerized exercise, physical therapy, or rehabilitation apparatus, preferably, an apparatus which permits concentric and eccentric isokinetic exercise by a user. One embodiment of the user force application device comprises a hollow outer cylinder, an inner cylinder inserted into the hollow outer cylinder and in co-axial alignment therewith, the inner cylinder being freely rotatable around its axis and freely slidable within the hollow outer cylinder along its axis. Grips of different size and shape can be provided which can easily be attached to the inner cylinder. The movement of the inner cylinder inside the hollow outer cylinder can be restricted. By attaching a larger cylinder to the inner cylinder and in co-axial alignment with it, rotational resistance can be provided. The user force application device can be secured to the exercise, physical therapy, or rehabilitation apparatus. The user force application device allows a user to perform various combinations of multiplaner movements of the joints from the shoulder to the fingers.
