Ankle-Foot Orthosis (AFO): Restoring Mobility for the Foot and Ankle

The ankle-foot orthosis (AFO) is prescribed for a range of conditions: hemiplegia following stroke, spinal cord injury sequelae, effects of polio, or peripheral nerve damage from trauma affecting the foot-dorsiflexor muscles. It works by supporting and controlling ankle movement, helping patients walk more easily and safely while preventing the toe-drag typical of foot drop caused by weakness or paralysis of the anterior tibial muscle.

The effectiveness of AFOs in supporting gait is also documented in international literature: a systematic review and meta-analysis published in Scientific Reports (2021) in stroke patients found that AFOs improved walking speed, cadence, and stride length, while also improving ankle dorsiflexion angle at initial contact and increasing foot clearance during the swing phase — though most available evidence still focuses on immediate or short-term effects, with long-term comparative data remaining limited.

Clinical experience at the practice shows clear improvement in many cases with AFO use. One male patient with anterior tibial paralysis and Achilles tendon contracture after an accident, initially walking with crutches and a roughly 30-degree foot drop, was fitted with an AFO featuring a hydraulic piston for gradual stretching; after about three months of consistent use, his ankle range of motion improved enough for him to begin standing and walking independently. Another patient with ankle paralysis from spinal cord injury regained the ability to stand and walk after more than a year of treatment combined with an AFO, which has since become an indispensable tool in her daily life and work.

AFOs are also used effectively to correct congenital clubfoot in young children, particularly after the plaster-casting stage of the Ponseti method, or for children diagnosed later when casting is no longer suitable. Compared with the traditional Dennis-Brown brace, the AFO offers better breathability, is easier to remove and clean daily, and allows the corrective tension to be adjusted flexibly at each stage without needing a new brace. Treatment duration for clubfoot with an AFO typically ranges from 3 to 36 months or longer, depending on each child's response.
