经筋疗法最早记载于《黄帝内经》,是以十二经脉为纲,结合解剖学基础总结人体肌肉、韧带等生理病理规律的中医外治手段。其核心机制是通过清理循行路径上的病理性“筋结点\"并同步刺激穴位,实现“以点治面\"的靶向治疗[1]。研究表明,经筋疗法在部分神经系统疾病防治中较传统经脉疗法更具优势[2-3],其可通过优化神经网络排布、改善脑血流及增强认知功能(如记忆力、注意力)等发挥作用[4-6]。推拿可通过多途径促进神经网络重塑[6-7],但有关其神经调控效应的影响因素却鲜有报道。
作为经络系统的重要组成部分,经筋按循行可分为手足三阳经筋与三阴经筋7,其中三阳经筋上行至头面部,与中枢神经系统解剖分布高度重叠,提示三阳经筋治疗可能对神经网络产生更显著调控效应。经筋疗法在中枢神经疾病中虽应用广泛,但其疗效缺乏客观定量评估体系,制约了个体化治疗方案的优化。静息态BOLD-fMRI以多参数定量解析脑的活动状态[8],基于图论方法能从全脑网络的宏观视角分析不同经筋疗法干预下神经网络能耗和效率等生物学特性,对其全脑网络优化效果进行定量研究[9]。本研究拟利用rfMRI结合图论方法分析不同类型经筋疗法干预前后静息态功能脑网络的拓扑结构,探究经筋循行路径对功能网络重塑作用的影响,为完善经筋理论、定量其疗效、指导临床治疗提供影像学证据。
