Full Definition
An Ankle–Foot Orthosis (AFO) is one of the most commonly prescribed lower-limb orthotic devices, extending from just below the knee to the foot. It is used to manage conditions including foot drop, spasticity, and post-stroke gait dysfunction. Editors encounter this acronym frequently in rehabilitation notes, prescription forms, and insurance documentation. The hyphen in 'Ankle–Foot' is conventionally an en dash in formal clinical writing, reflecting a range or compound relationship. AFO should be spelled out on first use in all patient-facing or public documents.
Usage
Usage note: Spell out on first mention. Note that 'Ankle–Foot' conventionally takes an en dash in formal publications. Do not write 'AFO orthosis' (redundant).
