电针经筋结点在卒中后痉挛性瘫痪的临床研究进展

Clinical Research Progress on Electroacupuncture at Myofascial Trigger Points in Spastic Paralysis after Stroke

摘要: 背景与目的：卒中后痉挛性瘫痪(SPAS)发生率达30%~80%，严重影响患者健康。经筋结点是经筋理论中筋肉结聚的关键部位，电针刺激可能通过神经调控改善痉挛。本研究旨在系统分析电针经筋结点治疗SPAS的临床应用规律、疗效及作用机制。方法：通过系统回顾国内外相关文献，从经筋理论、作用机制、选穴规律、电针参数、临床疗效等方面综合分析。结果：临床研究显示常用经筋结点主要分布于阳明经筋和太阳经筋；电针多采用100 Hz疏密波，15~30分钟/次，每周5~6次，持续4周；分析示电针可显著改善MAS评分和FMA评分，有效率较高。机制研究表明电针通过多级调控发挥作用：脊髓水平抑制γ运动神经元、增强GABA能功能；中枢水平促进皮层功能重组；分子水平调节神经递质平衡、上调神经营养因子。结论：电针经筋结点治疗SPAS疗效确切，作用机制涉及脊髓–脑干–皮层多级神经网络调控。建议规范治疗方案，深化机制研究，推动临床规范化应用。

Abstract: Background and Objective: The incidence of Spastic Paralysis After Stroke (SPAS) ranges from 30% to 80%, which significantly affects the health of patients. The meridian knot points are the key areas where muscles congregate in the meridian theory. Electrical acupuncture stimulation may improve spasticity through neural regulation. This study aims to systematically analyze the clinical application patterns, efficacy, and mechanism of electrical acupuncture at meridian knot points for SPAS. Methods: Through a systematic review of relevant domestic and foreign literature, a comprehensive analysis was conducted from aspects such as meridian theory, mechanism of action, selection of acupoints, electrical acupuncture parameters, and clinical efficacy. Results: Clinical studies show that the commonly used meridian knot points are mainly distributed in the Yangming meridian and the Taiyang meridian; electrical acupuncture mostly uses 100 Hz sparse and dense waves, 15~30 minutes per session, 5~6 times per week, and lasts for 4 weeks; the analysis indicates that electrical acupuncture can significantly improve MAS scores and FMA scores, with a high effective rate. Mechanism studies show that electrical acupuncture exerts its effects through multiple levels of regulation: spinal cord level inhibition of γ motor neurons and enhancement of GABA function; central level promotion of cortical functional reorganization; molecular level regulation of neurotransmitter balance and upregulation of neurotrophic factors. Conclusion: Electrical acupuncture at meridian knot points for SPAS has definite efficacy, and the mechanism involves multi-level neural network regulation from the spinal cord to the brainstem to the cortex. It is recommended to standardize the treatment plan, deepen mechanism research, and promote its standardized clinical application.
