Therapeutic hand and arm exercise device
First Claim
1. A therapeutic range of motion hand, wrist, and forearm exercising device comprising:
- a baseboard;
restraint means, attached to said baseboard, for securely holding a patient'"'"'s forearm;
a hand board pivotally attached at one end to said baseboard providing movement in a plane parallel to said baseboard;
a handle adjustably attached to said hand board said pivoted end being disposed between said handle and said restraint means;
adjustment means, associated with said hand board, for adjusting the position of said handle in relation to said hand board; and
adjustable elastic means, attached between said baseboard and a second end of said hand board, for providing adjustable force between said baseboard and said hand board.

Abstract
A baseboard having an extension attached to one end for restraining a patient'"'"'s forearm and having a hand board pivotally attached to the other end providing adjustable force and movement in a plane parallel to the plane of the baseboard. The hand board has a handle adjustably attached perpendicular thereto for positioning against the patient'"'"'s hand. An adjustable force, in both direction and magnitude, can be easily applied to the patient'"'"'s injured arm or hand with elastic means. The force is adjustable so as to be applied in a direction and magnitude that will optimize the rehabilitation of the patient'"'"'s damaged tissue caused by a previous injury or surgery.

12. A therapeutic range of motion hand, wrist, and forearm exercising device comprising:
-
a baseboard having a first plurality of holes therein; an extension attached to one end of said baseboard; a pair of front plates each of said front plates having a first slot therein attached to said extension and positioned adjacent each longitudinal edge of said extension so that the longitudinal extent of each said first slot is angled from the shortest transverse dimension of said extension; a rear plate having a second slot therein attached to said extension so that the longitudinal dimension of said extension is parallel to the longitudinal extent of said second slot; a pair of middle plates each of said middle plates having a third slot therein attached to said extension between said pair of front plates and said rear plate and positioned adjacent each longitudinal edge of said extension so that the longitudinal extent of each said third slot is angled from the shortest transverse dimension of said extension; a plurality of friction plates, one of said plurality of friction plates positioned beneath each of said pair of front plates, rear plate, and pair of middle plates; a plurality of blocks having a bore extending therethrough, one of said plurality of blocks positioned over each of said pair of front plates, rear plate, and pair of middle plates; a plurality of rods, one of said plurality of rods extending through each bore of said plurality of blocks, one end of each said plurality of rods attaching to one of said plurality of friction plates; a plurality of cams, one of said plurality of cams attached to the other end of each of said plurality of rods; a plurality of levers, one lever attached to each of said plurality of cams; a hand board having a second plurality of holes therein pivotally attached to said baseboard, said hand board attached so as to pivot in a plane parallel to said baseboard; a handle; a fixed pin attached to said handle adapted to fit separately within each one of said second plurality of holes; a free pin detachably mounted on said handle adapted to fit separately within each one of said second plurality of holes; a knob attached to said hand board; a pin adapted to fit separately within each one of said first plurality of holes; and at least one elastic loop adapted to be attached between said knob and said pin whereby a force of predetermined magnitude and direction can be applied to an injury for optimizing the recovery of damaged connective tissue.
