Exerciser for lower leg, ankle, and foot muscles

An exerciser for use in rehabilitation of lower leg, ankle, and foot muscles, said exerciser including a base, a support for a foot, a connection between the base and the central part of the heel area of the support to be tilted in any direction by a foot held by said support and said connection including adjustable means operable to provide a wanted uniform resistance to such tilting of said support, said adjustable means including first and second relatively movable parts, one part including an arcuate scale parallel to the support with a portion exposed laterally thereof of graduations which are calibrated in terms of pounds of torque required to overcome the existing resistance and the other part counter-traversing said scale as the resistance is varied, the first graduation represents a prevailing resistance that holds the foot support against tilting in response to gravity.
