Summary
Ankle osteoarthritis (OA) is a painful, progressive condition that can severely limit physical activity and reduce quality of life. Rocker bottom (RB) shoes and ankle-foot orthoses (AFOs) are commonly used as non-surgical treatments for ankle OA. RB shoes have a curved sole in the toe to heel direction that may alleviate joint pain by reducing ankle range of motion (ROM). Similarly, AFOs may reduce joint motion by securing the foot and ankle within the ankle-foot orthosis (AFO) frame. This study aims to determine the ability of RB shoes and AFOs to improve mobility, by relieving pain and reducing joint ROM.
