2018年1月18日 · In this study, we focused on MEP features before rTMS and identified the features of subject that could influence the rTMS effect when the rTMS stimulus condition was changed. It was found that the peak to peak amplitude and onset latency of the MEP before rTMS were related to the effect of rTMS.

2018年1月18日 · MEPs with a small amplitude and early latency were little influenced by the inhibitive effect of 1 Hz rTMS, while MEPs with a large amplitude and late latency were readily affected by the inhibitive effect of 1 Hz rTMS. In this study, we focused on the MEP features before rTMS and identified the features of the subject that could influence the ...

运动阈值是指在连续刺激过程中，至少50%刺激在靶肌肉记录到MEP＞50μV的最小刺激强度，根据靶肌肉是否收缩，分为静息运动阈值（resting motor threshold，RMT）和活动运动阈值（active motor threshold，AMT）。 运动功能测定采用单脉冲经颅磁刺激（singlepulseTMS，spTMS），刺激部位为中央前回、中央前回前、后各1个脑回和肿瘤组织周边，刺激强度常采用105%RMT。 目前监测MEP的上肢肌肉包括拇短展肌、桡侧腕屈肌、桡侧腕 …

2015年9月1日 · Transcranial magnetic stimulation (TMS) is one method used to deliver electrical stimuli through the scalp in conscious humans. In general, single-pulse TMS (including paired-pulse TMS) is used to explore brain functioning, whereas repetitive TMS (rTMS) is used to induce changes in brain activity that can last beyond the stimulation period.

2022年3月14日 · 在靶肌肉完全松弛的状态下，rmt可应用目测法或运动诱发电位（mep）检测法来确定。 目测法操作标准：10次检测中5次可诱发出靶肌肉最小运动时的最低刺激强度。

2024年10月17日 · After receiving 1 Hz rTMS, stroke patients with MEP(+) showed significant changes in their bilateral cortical excitability (p < 0.05). At 8 weeks after intervention, 1 Hz MEP(+) group experienced higher changes in NIHSS, FMA, SAFE, and BI scores than other groups (p < …

根据能够被合理、方便确定的功能脑区定位，例如，根据在目标肌群记录到 运动诱发电位 （MEP）可以确定运动皮层M1位置。又如，以M1为原点，沿中轴线方向前进5cm即认定为背外侧前额叶皮层区域。

Motor-evoked potentials (MEPs) were measured before rTMS and after every 200 rTMS pulses. Eighteen hundred pulses were applied for each stimulation condition. Results showed that more pulses and stronger intensities lead to a larger decrease in MEP amplitude.

MagproR30rTMS添加MEP模块，将能够实时、动态地检测MEP，并且最多能同时显示10条MEP波形，操作者能够准确而快速地确定患者运动阈值。 除了方便运动阈值的检测，它Biblioteka Baidu能够用于检测中枢传导时间、皮层兴奋性（如募集曲线、皮层静息期、皮质内抑制&易化 ...

2023年2月23日 · 国际临床神经生理学联盟组织（IFCN）重新评估了2014年发表的关于重复经颅磁刺激(rTMS)治疗效果指南，参考了2018年底之前所有rTMS文献，总结出最新的临床指南，于2019年发表于国际权威杂志《Clinical Neurophysiology》。
