经颅直流电刺激在脑卒中康复中应用的文献计量分析

Application of transcranial direct current stimulation in stroke rehabilitation:a bibliometrics analysis

目的对经颅直流电刺激(tDCS)应用于脑卒中康复的相关研究进行可视化分析。方法检索Web of Science核心合集和中国知网自建库至2023年3月31日收录的tDCS用于脑卒中康复研究的相关文献,采用CiteSapce 6.2.R2软件绘制学科、发文量、国家、关键词以及共被引的可视化图谱。结果共纳入英文文献732篇,中文文献322篇,年发文量均呈上升趋势。英文发文量最多的国家是美国,被引频次最高的期刊是Stroke。较高关注度的关键词为虚拟现实、上肢、经颅磁刺激等。共被引文献的聚类词有失语症、稳态可塑性、运动恢复等。结论tDCS用于脑卒中康复领域的研究热度逐年提升,研究方向呈现出多元化趋势。研究热点包括脑卒中后运动、言语功能的恢复,以及与其他治疗手段(如重复经颅磁刺激、针刺等)的联合应用。未来tDCS与脑机接口、虚拟现实等新康复手段的结合,以及选择个性化刺激参数构建以患者为中心的tDCS模型,可能是该领域的研究趋势。

Objective To visualize and analyze the researches on transcranial direct current stimulation(tDCS)for stroke rehabilitation.Methods The Web of Science core collection and CNKI were searched for literature on the use of tDCS for stroke rehabilitation,since the establishment of the database until March 31st,2023.The literature was analyzed wtih Cite‐Sapce 6.2.R2 in term of disciplines,articles number,countries,keywords and co-citation,etc.Results A total of 732 articles in English and 322 articles in Chinese were included,and the number of articles was on the rise.The country with the largest number of publications was the United States,and the journal with the highest citation frequency was Stroke.The keywords with high attention in recent years were virtual reality,upper limb and transcranial magnetic stimulation.The clustering words of co-cited literature were aphasia,homeostatic plasticity,and motor recovery,etc.Conclusion The researches about tDCS for stroke rehabilitation are increasing year by year,and the research fields are diversified.The hotspots include rehabilitation for motor and speech,and combination with other therapy,such as repetitive transcranial magnetic stimulation and acupuncture.The combination of tDCS with new rehabilitation protocols such as brain-computer interfaces and virtual reality,as well as the selection of individualized stimulation parameters to construct patient-centered tDCS models may be hot in the future.
