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.
