| 摘 要： | 采用磁刺激腰骶部运动神经传导时间（ＭＮＣＴ）与磁刺激窝Ｆ波相结合测定运动神经根传导时间（ＭＲＣＴ）的方法，无痛无创地评估Ｓ１神经根功能。研究对象为５０名正常受试者和３０名Ｓ１神经根受损病人。结果表明：磁刺激ＭＮＣＴ在病人组均正常，而ＭＲＣＴ却明显异常，异常率为８７％，明显高于Ｆ波潜伏期的异常率７３％。因此，磁刺激运动诱发电位（ＭＥＰ）是诊断Ｓ１神经根病的一种有很大应用价值的方法。

| Abstract: | The function of sacral(S 1) nerve root in 50 normal subjects and 30 patients with S 1 nerve root damage was evaluated by means of motor root conduction time(MRCT) by detecting motor nerve conduction time(MNCT) through magnetic stimulation of the lumbosacral nerve and F wave through magnetic stimulation of the popliteal.Both were painless and non-invasive.The result showed that the MNCT was normal and MRCT was significantly abnormal in the patient group.The abnormality rate was 87%,apparently higher than that of the latency of F wave(73%).It was believed that the magnetic stimulation motor evoked potential might have a significant value of application to the diagnosis of S 1 radiculopathy. |
