Abstract
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.
