Ankle Foot Orthosis
Ankle-foot orthoses (AFOs) are orthoses or braces, usually plastic, encompassing the anklejoint and all or part of the foot. AFOs are externally applied, and are intended to control position and motion of the ankle, compensate for weakness, or correct deformities. They control the ankle directly, and can be designed to control the knee joint indirectly as well. AFOs are commonly used in the treatment of disorders that affect muscle function such asstroke, spinal cord injury, muscular dystrophy, cerebral palsy, polio, multiple sclerosis andperipheral neuropathy. AFOs can be used to provide support to weak or wasted limbs or to position a limb with tight, contracted muscles into a more normal position. They are also used to immobilize the ankle and lower leg in the presence of arthritis or fracture, and to correct foot drop. An AFO may also be referred to as a foot-drop brace.
