Jaw exerciser

摘要

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 which guide movement of a carriage according to the character of movement that is desired. The carriage is movable to thereby allow corresponding movement of a mandibular jaw member supported by the carriage relative to a maxillary jaw member supported by the exerciser body. Through suitable linkages, motion may be imparted to the carriage or resistance exerted against its motion by manual action, by a spring or by a motor. The linkage may provide for adjustment of mechanical advantage or range of motion through selection of slots or holes formed in parts of the linkage structure.
