重复神经电刺激 (ＲＮＳ)指超强刺激神经干在相应肌肉上记录的复合肌肉动作电位的方法。是用于诊断神经肌肉接头病变的特异性手段。该方法的创立基于 1895年Ｊｏｌｌｙ的观察 ,他发现当重复电刺激重症肌无力 (ＭＧ)病人的神经干时 ,肌肉收缩的程度逐渐减弱 ,故称为Ｊｏｌｌｙ试
Repeated Electro-Nerve Stimulation (RNS) refers to a method of super-stimulating the compound muscle action potentials recorded on the corresponding muscles of the neural stem. Is used to diagnose neuromuscular junction disease-specific means. The method was based on the observation of Jolly in 1895 that he found that the degree of muscle contraction gradually diminished as the nerve trunk of patients with repetitive electrical stimulation of myasthenia gravis (MG) became known as the Jolly trial
