摘　　要：对50例确诊为重症肥无力（MG）患者腹神经和副神经低频（3Hz、5Hz）重复电刺激（RNS）结果表明，在不同频率刺激下，所有患者腋神经的平均衰减幅度均大于副神经的平均衰减幅度，50例患者腋神经RNS均为阳性，而副神经RNS阳性者仅33例，说明应用RNS检查诊断MG时，腋神经的敏感性高于副神经。此外，对两种检查方法及其结果的可靠性进行了讨论。The repetitive nerve stimulations (RNS) on axillary and accessory at low frequency(3Hz, 5Hz) were performed on 50 patients diagnosed as myasthenia gravis (MG). The find-ings were that the mean decrement of all patients while stimulating axillary was greater thanthat of stimulating accessory no matter what frequency was used. In 17 patients the testswere diagnostic on axillary but not on accessory. This study showed that the axillary pro-vides the higher diagnostic value than accessory in the diagnosis of MG when using RNS.The results and reliability of the two methods were also discussed.
