Myotonic dystrophy is inherited as an autosomal dominant trait and is characterized by muscle weakness and wasting, delayed muscular relaxation after contraction (myotonic phenomenon), premature frontal baldness, cataracts, gonadal atrophy, cranial hyperostosis, and cardiac disorders (1). Muscle weakness and wasting are most pronounced in the facial, pharyngeal, and masticatory muscles, as well as the sternocleidomastoid muscles, the flexors and extensors of the forearms, the hands, and the quadricepts, and dorsiflexor muscles of the feet. The myotonia is most easily elicited in the muscles of the hand, forearm, and tongue and is often slight, causing little or no disability.
