Physical examination on admission. The patient presented with sudden, arrhythmic movements with intermittent loss of postural tone on his left upper limb, compatible with negative myoclonus. The second segment of the video (between 12 and 17 seconds) shows partial improvement of the myoclonus after administration of Phenobarbital 50 mg. The abnormal movements were later completely suppressed.
