An exerciser is provided for application of an anatomically applied force to the jaw for pivoting of the jaw at its tempero-mandibular joint or to provide a motion to the jaw, or resistance to motion of the jaw which is beneficial in facial orthopedics. A structure is provided having curvilinear guide tracks (60) which guide movement of a carriage (62) according to the character of movement that is desired. The carriage is movable to thereby allow corresponding movement of a mandibular jaw member (72) supported by the carriage relative to a maxillary jaw member (50) supported by the exerciser body. Through suitable linkages, motion may be imparted to the carriage or resistance exerted against its motion by manual action, resilient means or a motor. The linkage may provide for adjustment of mechanical advantage or range of motion through selection of slots (40) or holes 33 formed in parts of the linkage structure. <IMAGE> |
