An Ankle Foot Orthosis, also known as an AFO, is an orthotic device that attaches to the lower leg and foot to control the ankle joint. An AFO helps to keep the ankle in a neutral position (90 degrees to the lower leg). It is often made of molded plastic or graphite, and fit to the patient's lower leg.

What Is Ankle-Foot Orthosis? An ankle-foot orthosis is a mechanical medical device that attaches to the leg and foot to control the ankle’s position and motion, compensate for weakness, or correct deformities. Each ankle-foot orthosis serves two main functions. First, it acts as a supportive device for walking through different gait stages.

An AFO stands for Ankle Foot Orthosis. It is a device that helps stabilize and support the ankle and the foot. It also allows for mobility in other areas of the leg and helps a patient walk with less pain and other complications.
