本研究的目的是确定经颅磁刺激(TMS)获得的运动诱发电位(MEP)在评分者内部的可靠性。对16名健康受试者的初级运动皮质进行TMS检查。在15天内6次记录健侧上肢的运动阈值、MEP潜伏期和波幅。采用组内相关系数(ICC2，1)评价信度。除波幅(ICC=0.01~0.34)外，其余MEP的ICC在0.60~0.92之间。用所描述的TMS技术获得的男性总体上是可靠的，尽管MEP幅度表现出不太一致。
The purpose of this study was to determine the intra-rater reliability of motor evoked potentials (MEP) obtained through transcranial magnetic stimulation (TMS). TMS was applied over the primary motor cortex of 16 healthy subjects. Motor thresholds, MEP latencies, and amplitudes were recorded from the contralateral upper limb on 6 occasions over 15 days. An intraclass correlation coefficient (ICC 2, 1) was used to estimate reliability. The ICCs ranged from 0.60 to 0.92 for all MEP measures except amplitude (ICC = 0.0 1 to 0.34). MEN obtained with the TMS technique described are generally reliable, although MEP amplitudes demonstrated less consistency.
