Our aim was to evaluate with modern tools the efficacy of orthopedic shoes on gait disorders in Friedreich's ataxia. The case of a 26-year-old woman with Friedreich's ataxia is described. She mainly complained of fatigability, ankle instability, frequent falls and pain. Impairments involved a cerebellar syndrome, a proprioceptive deficit, an upper motor neurone syndrome and osteoarticular deformities. Gait disabilities included ataxia and requirement of a cane. Handicap concerned outings, altering quality of life. Orthopedic shoes combined with physical therapy were prescribed. Assessment of treatment was planned after one month. Self-assessment by the patient was noted. Clinical assessment was provided by physical examination and clinical gait analysis supported by video. Quantified assessment was performed with a Gaitrite system recording spatiotemporal gait parameters.
