基于CiteSpace近5年重复经颅磁刺激文献计量学及可视化分析

目的:通过对国内外近5年的重复经颅磁刺激(rTMS)相关研究进行文献计量学及可视化分析,概述其研究现状、热点以及热点演变趋势。方法:检索中国知网(CNKI)和Web of Science(WoS)数据库核心集2015—2019年rTMS的相关文献。运用CiteSpace软件对作者、国家和机构、关键词进行共现分析,对关键词进行聚类分析、时间演化分析、突显词(Burst)分析,同时绘制相应知识图谱。结果:CNKI检索共获得996篇文献,张通为高产作者,机构发文数最多的是首都医科大学康复医学院;WoS检索获得2086篇文献,JONATHAN DOWNAR为高产作者,国家发文数最多的是美国,中心度较高的国家是葡萄牙。国内外在rTMS领域的研究热点主要集中在对抑郁症、精神分裂症等精神类疾病的治疗,对脑卒中后遗症认知、运动功能障碍的恢复研究以及对大脑皮质各功能区的作用机制探索。预测该领域在未来一段时间内将继续深入rTMS对脑区功能影响的研究,并进一步揭示其作用机制。结论:运用CiteSpace对国内外近5年rTMS研究文献进行可视化分析,较为直观地反映了rTMS的研究现状、热点及热点演变趋势,为rTMS研究的选题、发展方向等提供一定参考。

Bibliometrics and Visual Analysis of rTMS in Recent Five Years Based on CiteSpace

Objective:To summarize the current research status,hot spots and their evolution trend through bibliometrics and visual analysis of the latest research on repetitive transcranial magnetic stimulation(rTMS)conducted in recent five years at home and abroad.Methods:The related literatures search of rTMS during 2015-2019 were conducted in CNKI and Web of Science(WoS).CiteSpace software was used to analyze the co-occurrence analysis of authors,countries and institutions,and keywords;conduct cluster analysis,time evolution analysis and Burst analysis on keywords,and draw the knowledge map.Results:A total of 996 articles were obtained from CNKI search,of which Zhang Tong,the author who had the most publications;the most published papers were from the School of Rehabilitation Medicine,Capital Medical University.A total of 2,086 literatures were obtained from WoS search.Jonathan Downar had the most publications.The most published country was the United States,and the high degree of center was Portugal.The research hotspots in the field of rTMS at home and abroad mainly focus on the treatment of mental illness such as depression and schizophrenia,the research on the cognitive sequelae of cerebral apoplexy,the recovery of motor dysfunction,and the exploration of the mechanism of action of each functional area of cerebral cortex.It was predicted that this field would continue to study its influence on brain region function and further reveal its mechanism in the future.Conclusion:CiteSpace software was used to visually analyze the research literature of rTMS in recent five years at home and abroad,which directly reflected the current research status,hot spots and their evolution trend of rTMS.It provided some references for the topic selection and future direction of rTMS research.
