Data_Sheet_1_Research hotspots and frontiers about role of visual perception in stroke: A bibliometric study.XLS

BackgroundVisual perception is a dynamic process of perceiving the environment through sensory input and transforming sensory input into meaningful concepts related to environmental visual knowledge. Many studies focusing on the role of visual perception after stroke have been published in various journals. However, a bibliometric analysis in the domain of visual perception after stroke is still lacking. This study aimed to deliver a visual analysis to analyze the global trends in research on the role of visual perception after stroke in the last 10 years.
MethodsThe literature was derived from the Web of Science core collection database from 2012 to 2021. The collected material was limited to English articles and reviews. CiteSpace and Microsoft Excel were used for bibliographic analysis.
ResultsA total of 298 articles were included in the analysis. The annual number of publications increased from 23 to 42 in the last decade. Rehabilitation was the main research hotspot (n = 85). Journal of Physical Therapy Science published the largest number of papers (n = 14). The most influential author, institution, and country were Rowe FJ (n = 17), League of European Research Universities (n = 45), and England (n = 54), respectively. The keywords with the longest burst period are field defect, hemineglect, disorder, and quality of life.
ConclusionThis study analyzes the papers on the role of visual perception after stroke in the past 10 years and provides a new perspective for research in this field. At present, the number of articles in this field is not large and the cooperation network is not close enough. In the future, it is necessary to strengthen the cooperation among various countries, institutions, and authors. In addition, large samples and randomized controlled trials are needed to identify the potential treatments and pathophysiology for visual perceptual impairment after stroke.

背景 视觉感知是通过感官输入感知周遭环境，并将感官输入转化为与环境视觉知识相关的有意义概念的动态过程。目前已有诸多针对卒中后视觉感知作用的研究发表于各类期刊。然而，当前卒中后视觉感知领域的文献计量分析仍较为匮乏。本研究旨在通过可视化分析，探究近十年卒中后视觉感知作用相关研究的全球发展趋势。
方法 本研究的文献数据源自2012至2021年的Web of Science核心合集数据库（Web of Science Core Collection Database），纳入分析的文献仅限英文期刊论文与综述类文献。本研究采用CiteSpace与Microsoft Excel开展文献计量分析。
结果 本研究共纳入298篇文献进行分析。近十年间，该领域的年发表文献量从23篇增长至42篇。康复学为该领域的主要研究热点（n=85）。《物理治疗科学杂志》（Journal of Physical Therapy Science）刊载的相关文献数量最多（n=14）。影响力最高的作者、机构与国家分别为Rowe FJ（n=17）、欧洲研究型大学联盟（League of European Research Universities，n=45）与英格兰（n=54）。突现持续时间最长的关键词为视野缺损（field defect）、半侧空间忽略（hemineglect）、功能障碍与生活质量。
结论 本研究对近十年卒中后视觉感知作用相关文献进行了系统分析，为该领域的研究提供了全新视角。当前该领域的文献总量仍相对有限，且学术合作网络尚不够紧密。未来需加强各国、各机构及研究者之间的学术合作。此外，还需开展大样本随机对照试验，以明确卒中后视觉感知障碍的潜在治疗方案与病理生理学机制。
