摘要
目的:对脊髓损伤(spinal cord injury,SCI)后认知障碍相关文献进行可视化分析和知识图谱绘制,总结该领域的研究现状,探讨未来研究方向.方法:以Web of Science(WOS)核心数据库作为数据来源,检索式为"TS=(cognitive impairment)AND TS=(spinal cord injury)",检索 1992 年 1 月 1日～2023 年 11 月 7日发表的SCI后认知障碍相关文献,应用Office Excel 2016对该领域的年发文量绘制折线图,应用CiteSpace(6.2.R4)软件对纳入文献的国家、机构、作者、关键词进行可视化分析.结果:共纳入462篇文献,年度发文量总体呈上升趋势,发文量排名前三的国家是美国、中国、加拿大,发文量排名前三的机构是Veterns Health Administration、US Department of Veterns Affairs、Harvard University.形成以 Arora Mohit、Shahabi Parviz、Bauman William A为代表的作者合作网络.研究热点主要集中在SCI后认知障碍的病理机制和评估体系的构建等方面.结论:SCI后认知障碍的研究关注度逐年升高,阐明SCI后认知障碍形成的病理机制、构建SCI后完整全面的认知功能评估体系以及探索有效的治疗策略是未来研究的热点.
Abstract
Objectives:To visually analyze and draw a knowledge map of the literature related to cognitive impairment after spinal cord injury(SCI),and to summarize the current research status in this field and ex-plore future research directions.Methods:The literature related to research on cognitive impairment after SCI with the subject of"cognitive impairment"and"spinal cord injury",published from January 1,1992 to November 7,2023 was retrieved from Web of Science(WOS).Office Excel 2016 software was used to plot a line chart for the annual number of publications in this field,and the authors,countries,institutions,authors,and keywords of the included literature were analyzed and displayed visually by Citespace(6.2.R4)software.Results:A total of 462 articles were included.The statistical analysis of annual publication volume showed an overall increasing trend,and the top 3 countries were USA,China,and Canada,and the top 3 institutions were Veterns Health Administration(VHA),US Department of Veterns Affairs,and Harvard University in terms of number of publications.Arora Mohit,Shahabi Parviz,and Bauman William A represented the author col-laboration network.Keyword analysis showed that the research focus was mainly on the pathological mecha-nism and evaluation system of cognitive impairment after SCI.Conclusions:Cognitive impairment after SCI is of increasing research concern year by year,elucidating the pathological mechanisms,establishing a compre-hensive cognitive function assessment system,and exploring effective treatment strategies are the future re-search hotspots.
