The myokymia in gastrocnemius muscles in all cases. The myokymia also appeared in both upper extremities in 5 patients,and in faces,waist,back,abdomen and all extremities in 2 patients. Muscle rippling movement was induced and increased by exercise,and persistent during sleep. The vermicular myokymia could be observed easily in the relaxation of the muscles. Electromyography tests showed myokymic discharges in 5 patients,but normal in 2 patients. 5 patients of them were cured with carbamazepine and phenytoin sodium.ConclusionThere are typical clinical features and effective treatment in the patients with idiopathic generalized myokymia.
