The prevalence of comorbid pain after spinal cord injury (SCI) is relatively high in clinical observations and has continued to increase over time. Neuropathic pain (70.14%) is the most popular subject in academic journals after SCI. However, studies that used the bibliometric method to analyze comorbid pain after SCI are still lacking. This study is aimed at combining and integrating acquired information to analyze the global trends of research on the comorbidity of pain after SCI in the last three decades (1990-2019).
Systematic works of literature published from 1990 to 2019 were obtained from the Web of Science Core Collection. CiteSpace software was used to analyze the relationship of publication year with the country, institution, journals, authors, references, and keywords. The regression analysis is used to evaluate the percentage of the category increase or decrease over time significantly. IBM SPSS Statistics was used in the statistical analysis.
A total of 730 publications were included in the analysis. A remarkable increase in the number of publications was observed in the study period ( < 0.05). A total of 202 academic journals focused on the categories of clinical neurology, neurosciences, and rehabilitation, and the annual growth rate of articles in these three categories was statistically significant ( < 0.05). The USA (356, 48.77%) and the University of Miami (64, 8.77%) were the country and institution with the highest number of publications, respectively. , which was the main journal for research on pain after SCI, had the most publications (88, 12.05%). Burst keywords showed that the individual, inflammation, and central sensitization with pain after SCI are the research development trends and focus in this research field.
Overall, this study provides the latest research direction for pain after SCI. This historical overview of research into pain after SCI will be a useful basis for further research into development trends, focus issues, cooperators, and cooperative institutions.
在临床观察中，脊髓损伤（SCI）后合并疼痛的发生率相对较高，且呈持续上升趋势。神经病理性疼痛（70.14%）是 SCI 后学术期刊中最常见的主题。然而，使用文献计量学方法分析 SCI 后合并疼痛的研究仍然缺乏。本研究旨在结合和整合已获取的信息，分析过去三十年（1990-2019 年） SCI 后合并疼痛研究的全球趋势。
从 Web of Science 核心合集获取 1990 年至 2019 年发表的系统文献工作。使用 CiteSpace 软件分析出版年份与国家、机构、期刊、作者、参考文献和关键词的关系。回归分析用于评估随时间显著增加或减少的类别的百分比。IBM SPSS Statistics 用于统计分析。
共纳入 730 篇文献进行分析。在研究期间，发表的文献数量显著增加（<0.05）。共有 202 种学术期刊专注于临床神经病学、神经科学和康复领域，这三个领域的文章年增长率具有统计学意义（<0.05）。美国（356，48.77%）和迈阿密大学（64，8.77%）是发表文献数量最多的国家和机构。《Pain》（88，12.05%）是研究 SCI 后疼痛的主要期刊，发表文献最多。突发关键词显示，个体、炎症和中枢敏化与 SCI 后疼痛是该研究领域的研究发展趋势和重点。
总体而言，本研究为 SCI 后疼痛提供了最新的研究方向。对 SCI 后疼痛研究的历史回顾将为进一步研究发展趋势、重点问题、合作者和合作机构提供有用的基础。
