ABSTRACT
Standing station and walking are due to musculo-artiicular balance perfect. Any modification of this balance has consequences on the functional plan and on the statics. The interest of the rehabilitation is to permit restoring to best this musculo-articular balance. The equipment of replacement for deficiences is integreated in the program of rehabilitation. We have preposed to a 49 year-old patient, active and presenting a facio-scapulo-humeral dystrophy, an orthosis to stabililize his deficit knee. Posturgraphic analysis has permitted to specify the balance of the patients with and without orthosis. A recording of analysis present walking has been achieved at this patient, and then it has been compared to the walking without orthosis. Real tool of rehabilitation, this orthosis has permitted the prevention of falls generated by the musculo-articular unbalance and the preciptation toward the lost of the walking diagram and the installation of the handicap
