Ankle Foot Orthosis

An ankle foot orthosis (often called an AFO brace) is a supportive device worn on the lower leg and foot to help stabilise the ankle and improve walking ability. It is designed to hold the foot and ankle in a more controlled position, which can make movement safer and more efficient. By supporting the ankle joint and guiding the foot during each step, an ankle foot orthosis can help reduce instability and make walking feel more controlled.

AFO braces are commonly used to help manage conditions such as foot drop, muscle weakness or nerve damage that affect how the foot lifts during walking. Without support, the toes may drag along the ground, increasing the risk of tripping. An ankle foot orthosis helps lift or position the foot correctly, allowing the user to walk with greater confidence and stability.

An ankle foot orthosis is often recommended for people who experience weakness or reduced control in the muscles that lift or stabilise the foot. This can occur after a stroke, nerve injury or spinal condition, and may also be associated with neurological conditions such as multiple sclerosis or cerebral palsy. In these situations, the orthosis helps support the foot and ankle so that walking becomes safer and less tiring.

Some people also use an AFO brace following injury or surgery affecting the lower leg, particularly if the ankle needs additional stability during recovery. A healthcare professional such as a physiotherapist, orthotist or doctor may recommend an ankle foot orthosis when extra support is needed to improve gait and reduce the risk of falls.

Foot drop is a condition where the front part of the foot cannot be lifted properly when walking. This usually occurs due to weakness or damage in the muscles or nerves that control ankle movement. As a result, the toes may drag on the ground during each step, which can make walking difficult and increase the risk of tripping.

An ankle foot orthosis for foot drop helps by holding the foot in a more neutral position, preventing it from dropping downward. By supporting the foot as it lifts during the walking cycle, the AFO brace allows the user to clear the ground more easily with each step. This can help improve walking safety and reduce strain on the leg muscles.

A properly fitted ankle foot orthosis should feel secure and supportive without causing pressure or discomfort. The brace should hold the ankle and foot in the intended position while still allowing natural movement where appropriate. Straps or fastenings should keep the orthosis in place, but they should not be tight enough to restrict circulation or cause irritation.

Most AFO braces are worn inside a shoe, so it is important to ensure there is enough room in the footwear to accommodate the brace comfortably. Supportive shoes with adjustable fastenings or slightly wider fittings often work best. If discomfort, rubbing or skin irritation occurs, the fit should be checked and advice from a healthcare professional may be needed.

Many people wear an ankle foot orthosis throughout the day, particularly when walking or standing for longer periods. However, it is usually recommended to build up wear time gradually, especially when using the brace for the first time. This allows the skin and muscles to adapt to the support provided by the orthosis.

Regular skin checks are important, particularly around the ankle, heel and shin where pressure points may occur. If redness, discomfort or irritation develops, it may indicate that the brace needs adjustment. Following guidance from a healthcare professional can help ensure the ankle foot orthosis is used safely and comfortably as part of daily mobility support.

Most ankle foot orthoses can be cleaned using warm water and mild soap to remove dirt or perspiration that may build up during daily use. Soft straps or liners should be cleaned regularly, especially if the brace is worn for extended periods. Keeping the orthosis clean helps maintain hygiene and can reduce the risk of skin irritation.

It is also important to inspect the brace regularly for signs of wear, such as damaged straps, loose fastenings or cracks in the material. If any part of the ankle foot orthosis becomes worn or damaged, it should be repaired or replaced to ensure it continues to provide proper support. Proper care and maintenance can help extend the lifespan of the brace while keeping it comfortable and effective to use.
