Over the past decade, many studies in the field of transcranial direct current stimulation (tDCS) in stroke have been published in scholarly journals. However, a scientometric analysis focusing on tDCS after stroke is still missing. The purpose of this study is to deliver a bibliometric analysis to investigate the global hotspots and frontiers in the domain of tDCS in stroke from 2012 to 2021. Articles and reviews related to tDCS in stroke were retrieved and obtained from the Web of Science core collection database from 2012 to 2021. Data visualization and analysis were conducted by using CiteSpace, VOSviewer, and Microsoft Excel 2019. Finally, 371 publications were included in the scientometric analysis, including 288 articles and 83 reviews. The results showed that the number of publications per year increased from 15 to 68 in the last 10 years. Neurosciences was the main research hotspot category ( = 201). was the most published journal with 14 papers. The most productive author, institution, and country were Fregni F ( = 13), the League of European Research Universities ( = 37), and the United States of America ( = 98), respectively. A burstness analysis of keywords and the literature indicated that current studies in the field of tDCS in stroke focused on poststroke aphasia, tDCS combined with robotic therapy, and anatomical parameters. The research of tDCS in stroke is predicted to remain a research hotspot in the future. We recommend investigating the curative effect of other different tDCS closed-loop rehabilitation methods for different stroke dysfunctions. In conclusion, this bibliometric study presented the hotspots and trends of tDCS in stroke over the last decade, which may help researchers manage their further studies.
在过去十年中，许多关于经颅直流电刺激（tDCS）在中风领域的研究已发表在学术期刊上。然而，针对中风后tDCS的科学计量分析仍然缺失。本研究的目的是进行文献计量分析，以调查2012年至2021年中风领域tDCS的全球热点和前沿。从2012年至2021年的Web of Science核心合集数据库中检索并获取了与中风中tDCS相关的文章和综述。使用CiteSpace、VOSviewer和Microsoft Excel 2019进行数据可视化和分析。最后，371篇出版物被纳入科学计量分析，其中包括288篇文章和83篇综述。结果表明，在过去10年中，每年的出版物数量从15篇增加到68篇。神经科学是主要的研究热点类别（=201）。发表论文最多的期刊是《》，有14篇论文。产出最多的作者、机构和国家分别是Fregni F（=13）、欧洲研究型大学联盟（=37）和美利坚合众国（=98）。对关键词和文献的爆发性分析表明，目前中风领域tDCS的研究集中在中风后失语症、tDCS与机器人疗法相结合以及解剖学参数上。预计中风领域tDCS的研究在未来仍将是一个研究热点。我们建议研究其他不同的tDCS闭环康复方法对不同中风功能障碍的疗效。总之，这项文献计量研究展示了过去十年中风领域tDCS的热点和趋势，这可能有助于研究人员规划他们的进一步研究。
