title: Ice-pack test in myasthenia gravis: electrophysiological basis.
abstract: We report the first study in which the repetitive nerve stimulation (RNS) test was performed in conjunction with the ice-pack test in three patients with myasthenia gravis. All three patients showed an unequivocal improvement in ptosis on the side where an ice pack was placed. RNS test in the facial nerve revealed a definite improvement in the decremental response. From this we conclude that the ice-pack test produces a clinical and electrophysiological improvement in myasthenia gravis.
