ABSTRACT:
A magnetically resistive exercise device for rehabilitative therapy provides a body with adjustably inclinable planar work surfaces and a curvilinear work surface all formed of magnetically permeable material. A movable exercise piece supportable by or on a user's hand or foot carries at least one magnet for user generated motion over the work surfaces. Therapeutic rehabilitation is provided by frictional resistance to movement of the exercise piece on work surface. The frictional resistance may be adjustably varied by number and strength of magnets carried in the exercise piece and by surface coverings of differing frictional characteristics on the exercise piece, the work surface or both.
