Paediatric Supramalleolar Orthoses
Supramalleolar orthoses (SMO) are a form of ankle-foot orthosis (AFO) for children, which is a medical device to help guide the gait development of a child. Unlike the AFO, SMO’s support extends just above the ankle bones (malleoli) and is less visible when worn in shoes.
SMO are most commonly in children with paediatric flat feet, particularly to improve their stability and allow them to develop better motor functions. SMOs are also used in other conditions such as toe-walking or metatarsus adductus.
