Abstract
Abstract A foot and leg brace assembly formed of three sections flexibly joined together. A first thigh section is a curved plate of a size to fit about the underside of a user's thigh, with the second leg section formed of a curved plate shaped to fit about the rear of the user's leg and the third foot section shaped to fit under the sole and behind the user's heel. All three sections are fitted with attachment straps, with the leg and thigh sections each fitted on their interior surfaces with a padding of foam rubber or plastic. A transverse bar is hinged to the rear of the sole of the foot section, and extends on both sides of the sole section, being held by a pair of opposed tension springs on an axis perpendicular to the axis of the foot section.
