An ankle exercising device comprising a substantially flat platform and a hemispherical member secured to the bottom surface of the flat platform at its diametric planar surface. The peripheral contour of the platform is preferably configured with respect to the center of the hemispherical member so that the maximum tilt angle of the platform at any peripheral point coincides with the average or normal degree of movement of the biomechanical ankle structure in that direction. At least the top surface of the platform includes indicia so that the foot can be placed in a proper position on the platform, whereby angular movement of the ankle on the device corresponds with the average maximum biomechanical function of the ankle structure.

An exercise and neurophysical training apparatus employable by a user, said user having a foot possessing a malleolar axis and a second metatarsal axis intersecting said malleolar axis at an intersection point, and said user also having an ankle about which said foot is continuously and omnidirectionally movable within a maximum extent defined by a dorsiflexural direction limit, a planar flexural direction limit, an eversional direction limit, and an inversional direction limit, said limits being those of an average healthy user; said apparatus comprising: a substantially flat platform having a pair of faces and a continuous circumferential edge; indicia means on at least one of said faces designating said intersection point of said malleolar and second metatarsal axes, and designating a foot position location over said point; and fulcrum means for tilting said platform securable to at least the other of said faces opposite said intersection point, such that said edge and said fulcrum means are abuttable against a floor surface when said foot of said user rests on said foot position location; wherein said edge includes: a first means for limiting movement of said foot, in said dorsiflexural direction, to said dorsiflexural direction limit; a second means for limiting movement of said foot, in said planar flexural direction, to said planar flexural direction limit; a third means for limiting movement of said foot, in said eversional direction, to said eversional direction limit; and a fourth means for limiting movement of said foot, in said inversional direction, to said inversional direction limit wherein said four limiting means are defined by four corresponding portions of said edge, and wherein said four corresponding edge portions define four corresponding average distances from said edge to said point, at least three of said corresponding average distances being different from each other.
