时间间隔对持续性θ爆发刺激预调控间歇性θ爆发刺激诱导运动皮质可塑性的影响
Effect of time intervals of priming continuous theta burst stimulationon on cortical plasticity induced by intermit-tent theta burst stimulation
摘要
Abstract
Objective To investigate the effect of continuous theta burst stimulation-intermittent theta burst stimulation(cTBS-iT-BS)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.关键词
