描述了一种在计算机控制下使用表面肌电图评估 MEP 促进的新方法。 在最大表面肌电图活动的 2% 至 6% 之间进行自愿收缩的经颅磁刺激产生的反应具有最短的潜伏期和最大的振幅和功率。 当便利化增加超过这个水平时，没有发生显着的变化。 这些结果与之前发表的使用力传感器的研究类似，证实了该系统作为监测随意收缩的替代方法的可靠性。 控制系统可能会提供一种简单、灵活、定量的方法，以确保在临床环境中进行测试时充分、可重复地促进肌电图干扰最小。
A new method of assessing MEP facilitation using surface EMG under computer control is described. Transcranial magnetic stimulation with voluntary contraction at a value between 2 and 6% of maximal surface EMG activity produced responses with shortest latencies and largest amplitudes and power. No significant changes occurred when facilitation increased beyond this level. These results are similar to previously published studies using a force transducer, confirming the reliability of the system as an alternative method of monitoring voluntary contraction. The controlling system may potentially provide an easy, flexible, quantitative method of ensuring adequate, reproducible facilitation with minimum EMG interference for testing in a clinical setting.
