Patients will be assessed before treatment, 2 months and 6 months after treatment among the 3 ICF domains. Impairments will be assessed by the Stoke Impairment Assessment Set (SIAS), the Ashworth and Tardieu scales (spasticity) and the MRC scale (muscle strength). Spasticity and gait disorders will quantitatively and objectively be evaluated by the muscle stiffness measurement (15) and an instrumented gait analysis (11). Disability will be evaluated by the ABILOCO scale (16) and the participation (quality of life) by the StrokeQol scale (17) and the SF-36 questionnaire.
