摘　　要：目的应用磁运动诱发电位(MEP)和肌电图(EMG)探讨Graves病(GD)神经肌肉受损临床价值。方法GD病组46例行MEP和EMG检查;正常对照组50例行MEP检查,31例行EMG检查。结果46例GD患者神经肌肉症状26例(56·5%),MEP异常38例(82·6%),EMG异常39例(84·8%);以MEP异常判断EMG异常敏感性87·2%,特异性89·5%;以EMG异常判断MEP异常敏感性89·5%,特异性87·2%。结论两种方法对CTM诊断异常率、敏感性和特异性相似;MEP主要对神经源性损害敏感,EMG主要对肌源性损害敏感,具互补性。Objective To investigate the neuromuscular changes and clinical value of Graves disease（GD） by using magnetic motor evoked potentials（MEP） and electromyography（EMG）. Methods MEP and EMG were measured in 46 cases of GD and 50 normal controls in which 31 got EMG measured. Results In 46 GD patients,26 eases had neuromuscular symptoms or signs（56.5 % ）, 38 with abnormal MEP（82.6 % ）, and 39 with abnormal EMG （84.8 % ）. The sensitivity of electromyography deduced from abnormal MEP was 87.2 %, and speciality was 89. 5% ;The sensitivity of MEP deduced from abnormal EMG was 89.5%, and speciality was 87.2%. Conclusion Measure of MEP and EMG show comparability in abnormity,sensitivity and speciality of CTM;MEP is mainly sensitive in neural damage and EMG is mainly sensitive in muscular damage,being complement for each other.
