AbstractAn exerciser for use in the rehabilitation of the leg, ankle, and foot muscles has a foot support connected to a base of a ball and socket joint enabling the support to be tilted in any direction by a foot supported thereby. The joint includes a threaded member operable to provide selected resistance to such tilting and a pointer and scale are also provided to enable the resistance to be correlated to the size of the supported foot.
