Abstract
A device to be held in the mouth of a patient who has limited jaw opening and to assist in the therapy. The device has a frame with opposite side members having adjustable lengths. A rotatable knob drives a threaded screw to change the tension applied to a pair of springs. The springs activate a cam to raise or lower an upper mouthpiece with respect to a lower mouthpiece and to thereby adjust the jaw opening of the patient.
