The physiopatholgical mechanism of this disease, due to a deletion of repeated units named D4Z4 located on 4q35, is still controversial. Up to date, no curative therapy is available for these patients. We proposed in the present study to test feasibility, clinical and biological tolerance and efficacy of shoulder muscle training by electrostimulation in a group of FSHD patients. 10 patients displaying classical FSHD phenotype participate to this study consisting in daily session of shoulder girdle and quadriceps muscles electrostimulation of 23 minutes for a period of 5 months.
