Ankle-Foot Orthotic (AFO)
An ankle-foot orthosis, or AFO, is one of the most commonly prescribed orthotic devices in podiatry. Worn on the lower leg and foot, it helps control ankle motion, support weakened muscles, and improve walking patterns, particularly in patients with foot drop, ankle instability, or post-surgery recovery needs.
This page covers how an AFO works, who needs one, and what types are available.
What is an Ankle-Foot Orthosis?
An Ankle-Foot Orthosis (AFO) is a custom made brace that wraps around the calf and foot. It holds the ankle in a neutral position, prevents the toes from dragging during walking (a problem known as foot drop), and reduces the risk of tripping or falling. Unlike off-the-shelf ankle supports, a properly fitted AFO is tailored to your specific anatomy and condition.
How Does It
Work?
The AFO uses a three-point pressure system to control ankle motion. By pressing at the calf, the back of the heel, and under the foot, it stabilises the joint during the swing phase of walking while allowing some movement where appropriate.
Modern AFOs are made from lightweight materials, rigid versions for maximum support, or dynamic ones that store and release energy with each step.
What Conditions Does it Treat?
- Foot Drop — caused by stroke, nerve injury, or multiple sclerosis. The AFO lifts the toes to prevent tripping.
- Ankle Arthritis — reduces pain by limiting joint movement during walking.
- Post-Surgery Recovery — protects surgical repairs (e.g. Achilles tendon, ankle fracture) while allowing early mobilisation.
- Muscle Weakness — conditions like cerebral palsy, muscular dystrophy, or post-polio syndrome where the ankle lacks strength to clear the ground during walking.
What Types of AFOs Are Available?
Richie Brace
Low-profile, fits inside most shoes. Ideal for active patients with mild-to-moderate foot drop.
Carbon Fibre AFO
Ultra-light and spring-loaded. Returns energy during walking and is good for partial foot drop or post-stroke recovery.
Hinged AFO
Allows controlled ankle movement while preventing foot drop. Commonly used in paediatric and rehabilitation cases.
