Motor mapping using transcranial magnetic stimulation has been applied to the study of adaptive and restorative mechanisms of the motor cortex. To date, the reproducibility of mapping techniques has yet to be investigated in detail and/or confirmed. We report a technique used to map the abductor pollicis brevis (APB) and abductor digiti minimi (ADM) motor cortices of 6 normal volunteers, each studied on 2 occasions separated by several weeks (range of 21-132 days). APB and ADM results were analyzed separately, with area and volume characteristics subjected to analysis of variance. Coefficients of variation, which should be low, ranged from 14% to 37% and coefficients of reliability, which should be high, ranged from 63% to 94%, indicating that the described technique for motor mapping is responsible.
使用经颅磁刺激进行运动功能定位已应用于运动皮层适应性和恢复机制的研究。迄今为止，定位技术的可重复性尚未得到详细研究和/或证实。我们报告了一种用于对6名正常志愿者的拇短展肌（APB）和小指展肌（ADM）运动皮层进行定位的技术，每位志愿者均接受了两次研究，两次研究间隔数周（21 - 132天）。分别对APB和ADM的结果进行分析，对面积和体积特征进行方差分析。变异系数（应较低）范围为14%至37%，可靠性系数（应较高）范围为63%至94%，表明所描述的运动功能定位技术是可靠的。
