Hinged Dorsiflexion Assist Supra Malleolar Orthosis (SMO)
The SMO gets its name from the part of the body it encompasses.Thus this orthosis supports the leg just above the ankle bone or malleoli.
The London Orthotic Consultancy prescribe this orthosis in cases where there is mild weakness in the dorsiflexors combined with significant collapse of the foot and ankle.
It allows dorsiflexion and plantar flexion(toes up and toes down) but eliminates mediolateral movement. The SMO helps improve standing, balance and walking.
