国内外虚拟现实技术治疗脑卒中的知识图谱分析

Knowledge graph analysis of virtual reality technology in stroke treatment

背景:脑卒中因其高发病率、高死亡率、高致残率和高复发率已经成为全世界面临的棘手疾病之一,而传统的康复手段因见效慢、效率低、训练枯燥等问题对治疗脑卒中收效甚微,随着科技的发展,虚拟现实技术不仅具有简单高效、安全性高、趣味性强、价格低廉、实时反馈等特点,而且还能解决医患比例失衡等问题,促进了远程康复医疗的发展,对康复脑卒中患者具有极为重要的现实意义。目的:利用CitespaceⅤ知识图谱软件把握国内外虚拟现实技术在脑卒中的研究热点和进展,同时厘清该领域的结构模式并预测可能的发展趋势。方法:以Web of Science^(TM)核心集合库和CNKI的核心期刊、CSSCI、CSCD数据库2007年以来收录的、研究主题为虚拟现实技术治疗脑卒中的共1374篇核心文献为数据来源,通过CitespaceⅤ知识图谱软件利用知识图谱分析的方法研究国内外虚拟现实技术在脑卒中治疗的研究现状,并从学科、国家、作者、机构、研究热点等方面对比分析了国内外该治疗技术的差异,同时预测国内外未来虚拟现实技术可能的发展方向。结果与结论:①国外在该领域形成了以神经科学、计算机科学、生物医学工程为主的,多学科、多领域的综合性交叉学科群;国内学科较为单调,未形成明显的学科群体。②国外各国家/地区、作者、机构间形成了交流密切的合作关系网络,形成了高中心性的国家、作者、机构;国内作者、团体、机构之间合作关系较差,存在地域限制,缺乏有影响力的学术团体和机构。③国内外研究内容存在差异,且国外该技术有4个发展阶段。④国外未来研究的可能趋势是远程康复医疗、机器人辅助疗法、虚拟康复系统的研发及评价、突出虚拟康复疗法的筛选;国内未来可能的研究主题或许是虚拟现实技术与其他方法对具体部位的联合治疗的效果及评价、先进技术的引进和开发等。

BACKGROUND:Stroke has become one of the thorny diseases facing the world due to its high morbidity,high mortality,high disability rate,and high recurrence rate.However,traditional rehabilitation methods,characterized by slow effect,low efficiency,and dull training,elicit little effects in the treatment of stroke.With the development of science and technology,virtual reality technology which has the characteristics of simplicity,high efficiency,high security,strong interest,low price,and real-time feedback can solve the imbalance of doctor-patient ratio,promote the development of remote rehabilitation medicine,and has extremely important practical significance for the rehabilitation of stroke patients.OBJECTIVE:To study the research hotspots and progress of virtual reality technology in stroke treatment using Citespace V knowledge graph software,and to clarify the structural model of this field and predict the possible development trends of virtual reality technology worldwide in the future.METHODS:A total of 1374 core articles addressing virtual reality technology published since 2007 were retrieved from Web of Science^(TM),CNKI,CSSCI,and CSCD database and used as data sources.Citespace V knowledge graph software was used to analyze the research status of virtual reality technology in stroke treatment.In addition,the domestic and foreign differences in disciplines,countries,authors,institutions,and research hotspots were compared.Then,the possible development trend in the future was predicted.RESULTS AND CONCLUSION:The foreign countries have formed a multi-disciplinary and multi-domain comprehensive group,focusing on neuroscience,computer science,and biomedical engineering.Domestic disciplines are relatively monotonous,and no obvious discipline group has formed.There is a network of close exchanges and cooperation that has formed between foreign countries/regions,authors,and institutions,forming a high school mentality of countries,authors,and institutions.The cooperation among domestic authors,groups and institutions is poor,with geographical restrictions,and there is a lack of influential academic groups and institutions.There are differences in research contents at home and abroad,and there have been four development stages of this technology in foreign countries.The possible trends of future research abroad are the research,development and evaluation of remote rehabilitation medicine,robot-assisted therapy,and virtual rehabilitation system,highlighting the screening of virtual rehabilitation therapy.The possible future research topics in China may be the effect and evaluation of the combined treatment of specific parts with virtual reality technology and other methods,and the introduction and development of advanced technology.
