ABSTRACT:
An exercising device, especially for physical therapy, is formed of two planar members connected at an angle and sandwiching therebetween a sponge member of angular conformation to constitute a compressible structure. The sponge member is replaceable to provide selectivity with respect to compression and with respect to angular relationship between the planar members. A further planar member is optionally and adjustably connected to the compressible structure to provide a heel rest. A strap is provided to encircle the compressible structure and to hold an operator's extremity, such as a foot or hand, thereon. Flat rigid members are optionally usable to enable the device to be employed for dorsiflexion rather than plantiflexion. In this case the structure is mounted on top of the foot with the rigid members sandwiching the foot and exercising device therebetween.
