Study of virtual reality for mild cognitive impairment:A bibliometric analysis using CiteSpace

虚拟现实技术在轻度认知障碍患者中应用的文献计量学分析

Objectives Non-invasive and low-cost virtual reality(VR)technology is important for early evaluation and intervention in mild cognitive impairment(MCI).This study aimed to demonstrate the current status of overseas and domestic research as well as the focus and frontier of VR technology among individuals with MCI through a bibliometric analysis.Methods Studies from the core collection of Web of Science™between 1995 and 2020 were used;furthermore,CiteSpace 5.7 R3 was utilized to analyse information on authors/cited authors,keywords,burst words,and cited references.Results In total,230 publications were identified.Most studies were published in the USA(45 publications)and Italy(41 publications),where Guiseppe Riva ranks first(14 publications),and Tarnanas I is the author with the highest centrality(0.44).The hot topics in VR applications in the MCI population are‘physical activity,’‘people,’‘single-blind,’‘disease,’‘walking,’‘technology,’‘working memory,’and‘risk’in recent years.The keyword‘mild cognitive impairment’has attracted extensive attention since 2012,showing the strongest citation outbreak(8.28).The clustering results of the literature show the research types and emerging trends,including‘exergame,’‘serious games,’‘spatial navigation,’‘activities of daily living,’‘exercise,’‘enriched environment’and‘wayfinding.‘Conclusions Cognitive assessment and nonpharmacological intervention research on patients with MCI have become the focus of dementia prevention in recent years.Virtual technology,combined with traditional methods such as exercise therapy,provides new ideas for innovative cognitive evaluation and cognitive intervention.

目的无创低成本虚拟现实技术对于轻度认知障碍患者的早期评估和认知干预具有重要意义。本研究旨在通过文献计量学分析,展示虚拟现实技术在轻度认知障碍患者中的国内外研究现状、研究重点和前沿。方法在Web of Science中检索1995—2020年关于虚拟现实技术在轻度认知障碍患者中的应用研究,并利用CiteSpace 5.7 R3分析作者/被引用作者、关键词、突发词和被引用参考文献的信息。结果总共检索出230篇论文。大多数研究来自美国(45篇)和意大利(41篇),其中Guiseppe Riva发表数量排名第一(14篇),Tamanas I是最权威的作者,具有较高的中心性(0.44)。近年来,在轻度认知障碍人群中应用虚拟现实技术的热词包括“体力活动”“人”“单盲”“疾病”“行走”“技术”“工作记忆”和“风险”。关键词“轻度认知障碍(mild cognitive impairment)” 2012年起引起研究者广泛关注,显示出最强的引用暴发(8.28)。文献聚类分析结果显示,“运动游戏”“严肃游戏”“空间导航”“日常生活活动”“锻炼”“丰富环境”和“寻路”等研究方向是未来研究趋势。结论近年来,对轻度认知障碍患者的认知评估和非药物干预研究已成为痴呆预防的重点。虚拟技术与运动疗法等传统方法相结合,为认知评估和认知干预创新提供了思路。
