ABSTRACT:
The present invention relates to a therapeutic exercise device comprising at least one closed container formed from flexible, substantially inextensible sheet material, said container being shaped to permit compression of same by two portions of a human body and being filled with fluid to partially pressurize the interior of said container, the pressure within said container being less than that required to make the container rigid, said container being formed into at least two compartments, each of said compartments being in direct fluid communication with at least one other of said compartments via at least one passage to inhibit the flow of fluid between said compartments in response to an external force applied to at least one of said compartments by movement of one of said human body portions to reduce the volume of said one compartment whereby the remainder of said compartments expand in volume thereby exerting a movement inducing force on the other one of said human body portions.
