An AFO is brace that is designed to couple the foot and lower leg together in order to restore more optimum function to the entire lower extremity. AFO’s come in many different styles and are fabricated from a wide variety of materials including plastics, leather and carbon graphite. Very frequently these devices are custom made over a three dimensional model of a patient’s foot and leg and are prescribed and dispensed by health care practitioners. AFO’s are usually worn in extra depth shoes.

AFO’s are generally used in situations where less aggressive therapies have not resolved a patients complaint. It is very common for patients to be prescribed custom foot orthotics first to determine whether an AFO will be necessary. AFO’s are used in a very wide range of clinical situations. Some of the more common uses would include:

• Chronic ankle instability
• Arthritis
• Neuromuscular problems (post stroke etc.)
• Tendonitis of the ankle or heel
• Severe pain in the ankle or heel
• Collapse of the ankle or foot
• Arch pain

The conditions for which AFO’s are prescribed are often quite severe. It is very common to find that patients who need AFO’s are unable to walk comfortably (or at all) without them. Your health care provider will specifically instruct you regarding their proper use and care.

Custom made AFO’s will dramatically change the function of the foot and leg bones and muscles. As a result of these changes, patients will notice that things feel “different”. The exact sensations differ from patient to patients and from brace to brace. All AFO’s should be gradually “broken in” so that you are able to properly able to acclimate to the improved function of your lower extremity. Consult your health care practitioner for specific instructions for the care and use of the AFO’s.

As a result of the design and materials used to fabricate a custom made AFO, shoe fit is sometimes challenging. It is generally recommended that an extra depth shoes be used to accommodate and AFO appliance. Today there are many different styles of fashion friendly footwear available to patients who are required to wear and AFO. Langer carries a number of these. Ask your practitioner for more information.
