传统的双脉冲经颅磁刺激（TMS）技术评估皮质兴奋性的限制运动诱发电位（MEP）振幅的波动。本研究的目的是确定阈值跟踪TMS评估皮层兴奋性在临床环境中的可行性，并建立规范性数据。在26名健康对照者中进行了研究，跟踪拇短展肌的MEP反应。短间期皮层内抑制（SICI）发生在7-10 ms的刺激间期（ISI），在ISI为
Conventional paired-pulse transcranial magnetic stimulation (TMS) techniques of assessing cortical excitability are limited by fluctuations in the motor evoked potential (MEP) amplitude. The aim of the present study was to determine the feasibility of threshold tracking TMS for assessing cortical excitability in a clinical setting and to establish normative data. Studies were undertaken in 26 healthy controls, tracking the MEP response from abductor pollicis brevis. Short-interval intracortical inhibition (SICI) occurred up to an interstimulus interval (ISI) of 7-10 ms, with two distinct peaks evident, at ISIs of
