The value of orthoses for patients with Duchenne muscular dystrophy.

We applied knee-ankle-foot orthoses to 17 consecutive patients with Duchenne muscular dystrophy at the time they lost independent ambulation. We judged the value of the orthoses solely by the patients' ability to walk. With the orthoses, 7 patients (41%) became effective ambulators and benefited greatly from the appliances. Four patients (23%) had borderline results. Six patients (35%) were considered failures because they achieved only braced standing. We believe orthoses are indicated for many but not all patients with Duchenne muscular dystropy.
