Data_Sheet_1_Thirty years of research on traumatic brain injury rehabilitation: a bibliometric study.XLSX

BackgroundTraumatic brain injury (TBI) is a major public health concern with far-reaching consequences on individuals’ lives. Despite the abundance of works published on TBI rehabilitation, few studies have bibliometrically analyzed the published TBI rehabilitation research. This study aims to characterize current international trends and global productivity by analyzing articles on TBI rehabilitation using bibliometric approaches and visualization methods.
MethodsWe conducted a bibliometric analysis of data retrieved and extracted from the Web of Science Core Collection database to examine the evolution and thematic trends in TBI rehabilitation research up until December 31, 2022. The specific characteristics of the research articles on TBI rehabilitation were evaluated, such as publication year, countries/regions, institutions, authors, journals, research fields, references, and keywords.
ResultsOur analysis identified 5,541 research articles on TBI rehabilitation and observed a progressive increase in publications and citations over the years. The United States (US, 2,833, 51.13%), Australia (727, 13.12%), and Canada (525, 9.47%) were the most prolific countries/regions. The University of Washington (226, 4.08%) and Hammond FM (114, 2.06%) were the most productive institution and author, respectively. The top three productive journals were Brain Injury (862; 15.56%), Archives of Physical Medicine and Rehabilitation (630; 11.37%), and Journal of Head Trauma Rehabilitation (405, 7.31%). The most frequent research fields were Rehabilitation, Neurosciences, and Clinical Neurology. Co-citation references primarily addressed “outcome assessment,” “community integration” and “TBI management,” and “injury chronicity” and “sequelae” have gained more attention in recent years. “Mild TBI,” “outcome,” “stroke” and “children” were the commonly used keywords. Additionally, the analysis unveiled emerging research frontiers, including “return to work,” “disorder of consciousness,” “veterans,” “mild TBI,” “pediatric,” “executive function” and “acquired brain injury.”
ConclusionThis study provides valuable insights into the current state of TBI rehabilitation research, which has experienced a rapid increase in attention and exponential growth in publications and citations in the last three decades. TBI rehabilitation research is characterized by its multi-disciplinary approach, involving fields such as Rehabilitation, Neurosciences, and Clinical Neurology. The analysis revealed emerging research subjects that could inform future research directions.

背景：创伤性脑损伤（Traumatic Brain Injury, TBI）是一项重大公共卫生问题，对个体生活造成深远影响。尽管目前已有大量关于TBI康复的研究成果发表，但采用文献计量方法分析该领域已发表研究的报道仍较为匮乏。本研究旨在通过文献计量学方法与可视化手段，分析TBI康复相关文献，以阐明当前国际研究趋势与全球研究产出现状。
方法：本研究针对从Web of Science核心合集数据库（Web of Science Core Collection）中检索并提取的数据开展文献计量分析，旨在考察截至2022年12月31日的TBI康复研究的演进历程与主题趋势。本研究对TBI康复相关研究论文的多项特征进行了评估，包括发表年份、国家/地区、科研机构、作者、期刊、研究领域、参考文献与关键词等。
结果：本研究共检索到5541篇TBI康复相关研究论文，观测到历年发表文献数量与引用量均呈稳步增长趋势。美国（2833篇，占比51.13%）、澳大利亚（727篇，占比13.12%）与加拿大（525篇，占比9.47%）是发文量最高的三个国家/地区。华盛顿大学（226篇，占比4.08%）为发文量最高的科研机构，Hammond FM为发文量最高的作者（114篇，占比2.06%）。发文量排名前三的期刊依次为Brain Injury（862篇，占比15.56%）、Archives of Physical Medicine and Rehabilitation（630篇，占比11.37%）与Journal of Head Trauma Rehabilitation（405篇，占比7.31%）。高频研究领域涵盖康复医学、神经科学与临床神经病学。共引参考文献主要围绕“结局评估”“社区融入”与“TBI管理”展开；近年来，“损伤慢性化”与“后遗症”相关研究受到更多关注。“轻度TBI”“结局”“卒中”与“儿童”为最常用的关键词。此外，本研究还揭示了新兴研究前沿，包括“重返职场”“意识障碍”“退伍军人”“轻度TBI”“儿科人群”“执行功能”与“获得性脑损伤”。
结论：本研究为TBI康复研究的当前现状提供了宝贵的洞察：近三十年来，该领域的研究关注度持续提升，发表文献与引用量均呈指数级增长。TBI康复研究具有多学科交叉的特征，涉及康复医学、神经科学与临床神经病学等多个领域。本研究揭示的新兴研究主题可为未来的研究方向提供参考。
