Abstract
A walking brace is disclosed having inflatable air cells to provide therapeutic pressure to the patient's leg and which requires no external equipment or oral inflation tube for reinflation. Each air cell contains a piece of resilient foam, which allows air to come in through an external connection to inflate the air cell when the foam within the air cell expands and the external connection is open. Similarly, when the external connection is open, air leaves the air cell through the external connection in response to pressure on the air cell. However, once the external connection is closed, the air cell maintains its volume of air.
