Pain management is a constant struggle. Transcranial direct current stimulation (tDCS) is a neuromodulation technique with proved efficacy in chronic pain.
The aim of the study is to provide a bibliometric perspective regarding articles on pain and tDCS. Having a visualized and systematically overview of publication trends, new research ideas could arise for clinicians.
Articles on pain and tDCS were retrieved from Web of Science database. Using the R software version 4.1.2 and the "biblioshiny" R package, a quantitative and statistical analysis was performed. Time trend, number of publications, journals and authors, author country and institution, as well as citations and references were visualized.
A total of 554 publication fulfilled the criteria and were analyzed. The scientific production has been increasing over time with an annual growth of 17.1%. Brain Stimulation Journal and Journal of Pain are the leading journals regarding articles and citations. Fregni F. (83 articles) is the most prolific researcher with important authorship in the field. USA is the country with most authors involved in the topic (558 authors), whereas the leading institution is represented by Universidade Federal Rio Grande Do Sul (84 articles). Lefaucheur JP. article from 2017 has the maximum citations, while keywords in trend in the last three years are osteoarthritis and low back pain.
This is the first bibliometric study that reflects the trends of tDCS in the field of pain. Journals as well as authors are limited and clustered. However the number of articles as well as number of citations are constantly increasing, supporting the idea that this is an emerging topic. The information obtained could be an important practical basis for future pain management research.
疼痛管理一直是一项艰巨的任务。经颅直流电刺激（tDCS）是一种神经调节技术，已被证明对慢性疼痛有效。
本研究旨在从文献计量学角度对有关疼痛和tDCS的文章进行分析。通过可视化和系统地概述出版趋势，为临床医生提供新的研究思路。
从Web of Science数据库中检索有关疼痛和tDCS的文章。使用R软件4.1.2版本和“biblioshiny”R包进行定量和统计分析。对时间趋势、出版物数量、期刊和作者、作者所在国家和机构以及引用和参考文献进行了可视化展示。
共有554篇出版物符合标准并进行了分析。随着时间的推移，科研产出一直在增加，年增长率为17.1%。《脑刺激杂志》和《疼痛杂志》是发表文章和引用次数最多的领先期刊。弗雷尼·F.（83篇文章）是该领域最多产的研究人员，具有重要的作者身份。美国是参与该主题的作者最多的国家（558位作者），而领先的机构是南里奥格兰德联邦大学（84篇文章）。勒福舒尔·J.P. 2017年发表的文章引用次数最多，而过去三年的热门关键词是骨关节炎和腰痛。
这是第一项反映tDCS在疼痛领域趋势的文献计量学研究。期刊和作者数量有限且集中。然而，文章数量和引用次数都在不断增加，支持了这是一个新兴主题的观点。所获得的信息可能为未来的疼痛管理研究提供重要的实践基础。
