Abstract

In 17 myotonic cases (16 of myotonic muscular dystrophy and 1 of congenital myotonia), 13 cases showed significant decremental responses on RNS study. The decremental responses had the tendency of more prominence on faster stimulating rate, and in the proximal limb muscles. This result suggests that the RNS test is useful but not specific for the disorder of neuromuscular junction.
