Orthotic technique for dystonia musculorum deformans.

Tone reducing, inhibitive casting, and orthoses have been effectively used in patients with cerebral palsy and head injury to improve gait patterns and decrease tone. We present a patient with dystonia musculorum deformans who had severe inversion and supination of his left foot with weight bearing. He did poorly with metal double-upright ankle-foot orthoses with lateral T-strap. A tone-reducing ankle-foot orthosis (TRAFO) was successful in decreasing problems with abrasions and allowing him to walk without assistive devices.
