康复机器人领域10年研究热点:基于Web of Science数据库的文献计量学分析

Hot spots and frontiers of rehabilitation robot research in recent 10 years:a bibliometric analysis based on the Web of Science database

背景:由于传统的康复训练方法对慢性损伤患者的功能恢复效果有限,康复机器人在慢性损伤的康复训练中正得到越来越多的研究和应用。目的:解析和追踪近10年康复机器人领域相关研究的热点和前沿,为未来研究提供一定指导。方法:计算机检索2010-2020年在Web of Science数据库SCIE核心数据合集发表的康复机器人相关研究,检索条件为“TS=(rehabilitation robot OR rehabilitation robotics)”。运用CiteSpace 5.7可视化软件,从高影响力国家/地区、作者、高频关键词及突现词等方面解析康复机器人研究的热点与前沿。结果与结论:①最终纳入3194篇文献,近年来康复机器人的研究热度一直持续不减,相关文献年发表量呈现稳定增长的趋势,美国发文量位居首位,中国紧跟其后;②美国西北大学以发文量161篇位居机构第一位;瑞士苏黎世大学教授Riener R以发文量48篇位居作者第一位;③研究形成了9个具有代表性的关键词聚类,并随时间推移呈现研究重点和方向的转变趋势;④近10年研究热点主要集中在康复机器人的智能控制、任务分析与学习、性能和可靠性、康复机器人人机交互方式如何通过机器智能与生物智能的融合,实现机器人与人的自然、精准交互等方面;⑤目前,康复机器人在上肢和神经损伤领域的应用最广泛,关于脑机接口、虚拟现实、柔性可穿戴式、任务分析和外骨骼类的康复机器人研究越来越引起人们的关注,是近年来康复机器人研究的前沿和热点领域,代表着未来的研究发展趋势,是今后研究可以参考的方向。未来康复机器人领域的研究应着重关注以下方面:一是关注患者功能需求,提高生活质量;二是加强多学科交叉合作,构建区域国家合作网络。

BACKGROUND:Traditional rehabilitation training has limited potential to improve functional recovery from chronic injuries.Increasing attentions have been paid to the application of rehabilitation robots in rehabilitation training of chronic injuries.OBJECTIVE:To analyze and track the hot spots and frontiers of related research in the field of rehabilitation robot in the past 10 years,thereby providing some guidance for future research.METHODS:The literatures regarding rehabilitation robots published from 2010 to 2020 were retrieved in the Web of Science core database by computer.Search strategy was TS=(rehabilitation robot OR rehabilitation robotics).CiteSpace 5.7 visualization software was used to analyze the hot spots and frontiers of rehabilitation robot research from the aspects of high-influence countries/regions,institutions,authors,high-frequency keywords and burst words.RESULTS AND CONCLUSION:A total of 3194 literatures were included.In recent years,the research on rehabilitation robots has been growing steadily.The number of relevant literatures published annually shows a steady increase trend.The number of articles published by the United States ranks first,followed by China.Northwestern University in the United States ranks first with 161 articles published.Professor Riener R,from the University of Zurich,Switzerland,has published 48 articles,ranking the first among the authors.Nine representative keyword clusters have formed,and the research emphasis and direction change over time.In recent 10 years,the relevant research focuses on intelligent control of rehabilitation robots,task analysis and learning,performance and reliability,and how to realize the natural and accurate interaction between robot and human through the integration of machine intelligence and biological intelligence.At present,rehabilitation robots are the most widely used in the field of upper limb and nerve injuries,and the interest in brain-machine interface,virtual reality,flexible wearable,task analysis and the exoskeletons has increased in the research of rehabilitation robot,which are the frontiers and hot issues in recent years,representing the development trend of future studies,and referring to the future research direction.Future research in the field of rehabilitation robots should focus on the following aspects:First,focus on the functional needs of patients to improve the quality of life.Secondly,strengthen multidisciplinary cooperation and build a cooperation network among regional countries.
