摘　　要：肢体运动功能障碍作为卒中后的常见病症,急需有效的康复治疗手段以助其运动功能改善。近年来,诸如经颅电磁刺激等新型神经调控技术通过可逆性地调控神经系统活性,达到改善患者肢体运动功能障碍、增强康复效果的目的。本文在阐述经颅直流电刺激(transcranial direct current stimulation,tDCS)和重复经颅磁刺激(repetitive transcranial magnetic stimulation,rTMS)两种方法的作用机制基础上,对tDCS及rTMS分别在卒中后肢体运动功能康复中的神经可塑性机制、肢体运动功能康复刺激参数的研究、康复手段融合研究进行了回顾与总结,发现tDCS和rTMS均可促进患者大脑运动功能神经重组,与传统、现代技术治疗手段结合均可在运动功能康复方面发挥有效作用。而后归纳了影响二者临床应用的诸如刺激部位、tDCS最佳电流强度和rTMS最优频率等刺激参数设置不一致等问题。最后针对两种调控手段融合方式的探索性研究,展望了未来新型调控方法在临床的应用模式,为今后临床康复中面向肢体运动功能障碍的神经调控技术研究方法的设计、制定与优化提供新的技术思路。Stroke is the main cause of motor dysfunction in modern society.It is necessary to improve limb motor dysfunction through effective rehabilitation therapy.In recent years,transcranial electromagnetic stimulation and other new neuroregulatory techniques have effectively promoted the clinical development of stroke rehabilitation.By reversibly regulating the activity of the nervous system,these techniques can improve the limb movement dysfunction of patients and thus enhance the rehabilitation effect.On the basis of prior investigations,we expounded the mechanism and effect of transcranial direct current stimulation(tDCS)and repetitive transcranial magnetic stimulation(rTMS),also reviewed and summarized the neuroplasticity mechanism of tDCS and rTMS respectively in the clinical rehabilitation of limb motor function after stroke,the research on the stimulation parameters during rehabilitation,and the research on fusion rehabilitation methods.And we found that both tDCS and rTMS could promote the neural recombination of motor function,and those methods which combined with traditional and modern therapies were expected to play an effective role in motor function rehabilitation.In addition,we also summarized the inconsistencies of stimulation parameters such as the location of brain stimulation,optimal current intensity of tDCS and optimal frequency of rTMS,which limited their clinical application.Finally,we prospected the application mode of new regulatory methods in clinical practice.This paper provided a new technical idea for the design,formulation and optimization of neuroregulation techniques in clinical rehabilitation for limb motor dysfunction.
