BACKGROUND: Transcranial alternating current stimulation (tACS) can apply currents of varying intensity to the scalp, modulating cortical excitability and brain activity. tACS is a relatively new neuromodulation intervention that is now widely used in clinical practice. Many papers related to tACS have been published in various journals. However, there are no articles that objectively and directly introduce the development trend and research hotspots of tACS. Therefore, the aim of this study is to use CiteSpace to visually analyze the recent tACS-related publications, systematically and in detail summarize the current research hotspots and trends in this field, and provide valuable information for future tACS-related research. MATERIAL AND METHODS: The database Web of Science Core Collection Science Citation Index Expanded was used and searched from build to 4 August 2023. Using the CiteSpace to analyze the authors, institutions, countries, keywords, co-cited authors, journals, and references. RESULTS: A total of 677 papers were obtained. From 2008 to 2023, the number of publications shows an increasing trend, albeit with some fluctuations. The most productive country in this field was Germany. The institution with the highest number of publications is Carl von Ossietzky University of Oldenburg ( = 50). According to Bradford's law, 7 journals are considered core journals in the field. Herrmann, CS was the author with the most publications ( = 40), while Antal, A was the author with the highest number of co-citations ( = 391) and betweenness centrality ( = 0.16). Disease, neural mechanisms of the brain and electric stimulation are the major research areas in the field. The effect of tACS in different diseases, multi-site stimulation, combined treatment and evaluation are the future research hotspots and trends. CONCLUSION: tACS has research value and research potential, and more and more researchers are paying attention to it. The findings of this bibliometric study provide the current status and trends in the clinical research of tACS and may help researchers to identify hotspots s and explore new research directions in this field.
背景:经颅交流电刺激(tACS)可将不同强度的电流施加于头皮,调节皮层兴奋性和脑活动。tACS是一种相对较新的神经调节干预手段,目前在临床实践中广泛应用。许多与tACS相关的论文已发表在各类期刊上。然而,尚无文章客观、直接地介绍tACS的发展趋势和研究热点。因此,本研究旨在利用CiteSpace对近期与tACS相关的出版物进行可视化分析,系统、详细地总结该领域当前的研究热点和趋势,为未来tACS相关研究提供有价值的信息。 材料与方法:使用数据库Web of Science核心合集科学引文索引扩展版,检索时间范围为建库至2023年8月4日。利用CiteSpace分析作者、机构、国家、关键词、共被引作者、期刊和参考文献。 结果:共获得677篇论文。2008年至2023年,出版物数量呈上升趋势,虽有一些波动。该领域发文量最多的国家是德国。发文量最多的机构是奥尔登堡卡尔·冯·奥西茨基大学(=50)。根据布拉德福定律,7种期刊被视为该领域的核心期刊。Herrmann, CS是发文量最多的作者(=40),而Antal, A是共被引次数最多(=391)且中间中心性最高(=0.16)的作者。疾病、脑的神经机制和电刺激是该领域的主要研究方向。tACS在不同疾病中的作用、多部位刺激、联合治疗及评估是未来的研究热点和趋势。 结论:tACS具有研究价值和研究潜力,越来越多的研究者关注它。本文献计量学研究结果提供了tACS临床研究的现状和趋势,可能有助于研究者识别热点并探索该领域的新研究方向。
