OBJECTIVES
To introduce and to test a simple standardized motor threshold (MT) estimation procedure for transcranial magnetic stimulation (TMS) research.
METHODS
A 5-step MT estimation procedure was introduced, and interestimator reliability was tested by comparing MTs as determined by an experienced and a trainee TMS researcher in a double-blind design.
RESULTS
The parametric Pearson correlation between the MTs of the experienced and the MTs of the trainee TMS researcher was 0.95 (P < 0.001).
CONCLUSIONS
The currently proposed estimation procedure may be helpful in obtaining reliable MT values in experimental and clinical settings.
目的
介绍并测试一种用于经颅磁刺激（TMS）研究的简单标准化运动阈值（MT）估计程序。
方法
引入了一种五步MT估计程序，并通过双盲设计比较经验丰富的TMS研究人员和实习TMS研究人员确定的MT，来测试估计器的可靠性。
结果
经验丰富的研究人员的MT与实习TMS研究人员的MT之间的参数Pearson相关性为0.95（P < 0.001）。
结论
目前提出的估计程序可能有助于在实验和临床环境中获得可靠的MT值。
