摘要:

目的 探讨不同时间间隔的持续性-间歇性θ爆发刺激(cTBS-iTBS)预调控方案对初级运动皮质(M1)可塑性的影响。
方法 2024年3月至8月于常州市德安医院招募健康青年受试者39例。受试者随机交叉接受间隔5 min、10 min和15 min的cTBS-iTBS预调控方案,干预前和干预后0 min、10 min、20 min和30 min记录M1运动诱发电位(MEP)振幅。
结果 刺激方案(F = 19.761, P < 0.001)和测量时间(F = 10.224, P < 0.001)的主效应均显著;干预后各时间点,间隔10 min时,MEP振幅高于间隔5 min和15 min的方案(t > 3.010, P < 0.05)。
结论 cTBS后10 min施加iTBS可更有效增强M1的可塑性。

Abstract:

Objective To investigate the effect of continuous theta burst stimulation-intermittent theta burst stimulation (cTBS-iTBS) priming protocols with different time intervals on the plasticity of primary motor cortex (M1).
Methods A total of 39 healthy young adults were recruited from Changzhou De'an Hospital from March to August, 2024. Participants received cTBS-iTBS priming protocols with intervals of 5 minutes, 10 minutes and 15 minutes using a randomized crossover design. Motor-evoked potential (MEP) amplitudes in M1 were recorded at baseline (before intervention) and 0 minute, 10 minutes, 20 minutes and 30 minutes after intervention.
Results The main effects of stimulation protocol (F = 19.761, P < 0.001) and measurement time (F = 10.224, P < 0.001) were significant. At each time point after intervention, the MEP amplitude was significantly higher under the 10-minute interval than under the 5-minute and 15-minute intervals (t > 3.010, P < 0.05).
Conclusion The 10-minute interval of cTBS-iTBS is more effective on M1 plasticity.
