    • A walking brace for immobilizing and/or protecting the lower leg of a patien t comprises a leg portion adapted to fit substantially around the lower leg of a patient and a sole portion that fits beneath the patient's foot. The sole portion is provided with a dual layer of resilient shock absorbing material disposed along its bottom surface. The dual layer comprises an upper layer o f a relatively softer material and a lower layer of a relatively more durable material. The dual layer can provide good shock absorbency but can be made thinner to provide a lower profile. In another aspect of the invention, the walking brace is provided with one or more inflatable air cells to provide adjustable therapeutic pressure to the leg and the leg portion of the brace is in the form of a rigid shell provided with a protruding region for receiving the air cell outlet associated with each air cell such that the air cell outlet is directed toward the front of the walking brace for easy access by the user. In yet another aspect of the invention, the rigid shell member of the leg portion is provided with one or more longitudinal slits that allow expansion of the leg portion to accommodate an enlarged lower leg portion of a patient. The expanded leg portion can accommodate users with enlarged lower limbs, suchas those suffering from severe edema.

    • The pneumatic Achilles wrap comprises a wrap including at least one strap for fastening the wrap around the foot and around the ankle. The wrap positions an arch cell which contains a dynamic volume of air within the wrap under a human foot. The arch cell is fabricated from a flexible material and is in communication with a conduit member. Upon application of external pressure to the arch cell, air is expelled from said air cell through said conduit member. The wrap also positions a tendon cell which contains a dynamic volume of air within the wrap against the Achilles tendon. The tendon cell is in communication with the arch cell via the conduit member. The tendon cell is also fabricated from a flexible material. Upon the expelling of air from said arch cell, the air enters through the conduit member into the tendon cell which exerts a greater pressure against the Achilles tendon.
