ABSTRACT:
Therapeutic device for wearing by an individual on a lower extremity to facilitate rehabilitation of a injured foot, ankle and/or lower leg area by promoting venous blood flow in the injured area includes a first pressurized chamber configured for imparting fluid pressure to the injured area and a weight-responsive second chamber coactable with the first pressurized chamber for providing recurrent compression to the injured area by varying the fluid pressure imparted by the first pressurized chamber. The first pressurized chamber is dimensioned to surround substantially the injured area, and the weight-responsive chamber communicates fluidwise with the first chamber and is resiliently deformable volumewise upon impaction by a force to displace fluid alternately into and from the first pressurized chamber.
