【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。更多还原

【Abstract】 Objective To investigate the ne uromuscular changes and clinical value of Graves disease(GD) by using magnetic m otor evoked potentials(MEP) and electromyography(EMG).Methods M EP and EMG were measured in 46 cases of GD and 50 normal controls in which 31 go t EMG measured.Results In 46 GD patients,26 cases had neuromusc ular symptoms or signs(56.5%),38 with abnormal MEP(82.6%),and 39 with abnormal E MG(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 EM G show comparability in abnormity,sensitivity and speciality of CTM;MEP is mainl y sensitive in neural damage and EMG is mainly sensitive in muscular damage,bein g complement for each other.更多还原
