We report a case of continuous muscle activity, unusual from both the clinical and neurophysiological point of views. The neurological examination revealed a continuous rippling of muscles, but limited to the lower part of the face, to the forearm and to the muscles of the thenar eminence. All deep reflexes were normal. Hyperperspiration, spasms and stiffness of abnormal postures were absent. Electromyography displayed continuous motor unit discharges. An abnormal F wave was elicited only from the affected territories. The disappearances of the spontaneous activity and of the F wave occurred not only after the motor nerve block, but also after the block of the afferent sensitive fibres. Therapy with carbamazepine, hydantoin, diazepam and baclofen did not bring improvement.
我们报告了一例从临床和神经生理学角度来看都不寻常的持续性肌肉活动病例。神经系统检查发现肌肉持续波动，但仅限于面部下部、前臂和大鱼际肌。所有深反射均正常。无多汗、痉挛及异常姿势僵硬。肌电图显示运动单位持续放电。仅在受累区域引出异常F波。自发活动和F波不仅在运动神经阻滞之后消失，在传入感觉纤维阻滞之后也消失。卡马西平、苯妥英、地西泮和巴氯芬治疗均未带来改善。
