English Abstract:

  【Abstract】 Objectives: To visually analyze and draw a knowledge map of the literature related to cognitive impairment after spinal cord injury(SCI), and to summarize the current research status in this field and explore future research directions. Methods: The literature related to research on cognitive impairment after SCI with the subject of "cognitive impairment" and " spinal cord injury", published from January 1, 1992 to November 7, 2023 was retrieved from Web of Science(WOS). Office Excel 2016 software was used to plot a line chart for the annual number of publications in this field, and the authors, countries, institutions, authors, and keywords of the included literature were analyzed and displayed visually by Citespace(6.2.R4) software. Results: A total of 462 articles were included. The statistical analysis of annual publication volume showed an overall increasing trend, and the top 3 countries were USA, China, and Canada, and the top 3 institutions were Veterns Health Administration(VHA), US Department of Veterns Affairs, and Harvard University in terms of number of publications. Arora Mohit, Shahabi Parviz, and Bauman William A represented the author collaboration network. Keyword analysis showed that the research focus was mainly on the pathological mechanism and evaluation system of cognitive impairment after SCI. Conclusions: Cognitive impairment after SCI is of increasing research concern year by year, elucidating the pathological mechanisms, establishing a comprehensive cognitive function assessment system, and exploring effective treatment strategies are the future research hotspots.
