摘要 经颅直流电刺激(tDCS)在脑卒中治疗中应用潜力巨大,但其作用效应仍不明确。本研究基于脑电图(EEG)和图论分析探讨阳极tDCS干预对脑卒中患者的作用效应。对15例脑卒中患者施加阳极tDCS真刺激和伪刺激,以随机顺序间隔一周进行两次刺激,每次采集刺激前和刺激后静息态EEG信号。对每次采集的EEG信号,采用皮尔逊相关系数等分析方法研究各个导联间的关联性特征参数。基于分析结果,构建患者刺激前、后的脑功能网络,并分析网络特征参数的变化。结果显示,真刺激后脑功能网络的平均度、平均聚类系数、全局效率以及“小世界”属性值较刺激前均显著增大(P<0.05),特征路径长度显著减小(P<0.05),而伪刺激组相关参数变化未见显著差异(P>0.05)。结果表明,阳极tDCS干预对卒中后恢复性治疗具有积极影响,为其临床应用提供了实验依据。
