Abstract: A system for extending a finger of a hand comprises structural elements configured to be inserted into a flexed finger and capable of providing a controllable force to extend the finger. In some embodiments, structural elements comprise a cam connected to a spacer, the spacer connected to a first strut, and a second strut holding a loading assembly, an end piece and a spring. The loading assembly compresses or relaxes the spring, which exerts a variable force on the end piece, which rotates the cam and the first strut about an extension angle. When the extension angle is minimal, the first and second struts are substantially parallel. A method of extending a finger of a hand substantially fixed in a flexed position comprises inserting a system comprising structural elements into the finger and thereafter providing a force to extend the finger and maintaining the force for a period of time.

Abstract: A device for straightening a toe which has deviated away from a midline of a foot includes an assembly for retaining the toe, a tension mechanism and an assembly for securely positioning the foot in the device, such that when pressure is applied to the toe, the toe can be returned to its normal position. The tension mechanism is able to produce a graded amount of tension.

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.
