目的研究重症肌无力(MG)患者临床绝对评分和电生理检查结果的相关性。方法61例MG患者在进行临床绝对评分之后依次进行桡、腋、副和面神经低频重复电刺激(RNS)和伸指总肌单纤维肌电图(SFEMG)检查。通过SPSS100软件分析临床绝对评分与RNS和SFEMG结果的相关性。结果临床绝对评分与桡、腋、副和面神经低频RNS的波幅衰减程度之间均呈显著正相关;临床绝对评分与SFEMG结果中的平均jitter值、异常电位对比例和阻滞电位对比例之间呈非常显著正相关,而与正常电位对比例之间呈非常显著负相关。结论临床绝对评分的高低与电生理的检查结果间有很好的一致性,能够比较准确、客观地反映MG病情的严重程度。
Objective To investigate the correlation between clinical absolute score and electrophysiological findings in patients with myasthenia gravis (MG). Methods Sixty-one patients with MG were followed up for RNS and SFEMG of radial, axillary, accessory and facial nerve after clinical absolute score. SPSS100 software was used to analyze the correlation between clinical absolute scores and RNS and SFEMG results. Results There was a significant positive correlation between clinical absolute score and amplitude of attenuation of radial, axillary, accessory and facial nerve low frequency RNS. Between clinical absolute score and SFEMG, mean jitter value, abnormal potential contrast and blocking potential comparison Showed a very significant positive correlation, but with the normal potential contrast was a significant negative correlation. Conclusion There is a good agreement between the clinical absolute score and electrophysiological examination results, which can reflect the severity of MG condition more accurately and objectively.
