On the basis of published data and the investigators' results indicating that oxidative
stress may contribute to the peripheral skeletal muscle dysfunction in patients with FSHD,
the investigators propose a study to test whether or not an antioxidant supplementation has a
therapeutic interest for patients with FSHD. Their results have important implications for
the successful implementation of rational antioxidant therapy in FSHD in which cell loss
could be linked to oxidative stress.
