Abstract: A controlled motion ankle walker brace for facilitating the rehabilitation process of an injured ankle and other injuries to the ankle region of a patient. The device includes a liner which wraps around the lower leg, ankle and foot of the patient to snugly and cushioningly hold the foot, a rocker-type shoe into which the patient's foot is removably secured, and a hinge having a lower strut attached to the shoe and an upper strut extending along the lower leg of the patient. The upper strut has an enlarged axle to which the lower strut is rotatably attached such that the upper strut and lower strut rotate in relation to each other. A channel is formed in the lower portion of the upper strut and contiguously extends into the lower strut for receiving a chock. A variety of chocks, corresponding to various degrees of rotation are insertable into the channel to set the range of motion for the ankle walker brace in dorsiflexion and plantar flexion.
