Ankle-foot orthotic braces correct the position of the ankle and foot while supporting the muscle, explains Surgi-Care. Knee-ankle-foot orthoses are used to limit, stop or assist movement in any direction, according to Kawartha Regional Orthopedic Specialists.
These orthotic braces are used to address leg paralysis or muscle weaknesses, explains KROS. An ankle foot orthosis is made of thermoplastic materials, metal or a combination of both, notes Surgi-Care. A patient with an AFO needs to wear a Velcro or lace-up shoe that comfortably fits both the foot and the brace. Surgi-Care advises wearing a cotton sock between the brace and the skin to absorb perspiration and protect the skin.
