Pain is one of the most common symptoms in patients after stroke. It is a distressing experience that affects patients' quality of life, and it is highly prevalent in clinical practice. The pathogenesis mechanisms of PSP are not so clear, and there is currently a lack of effective medical treatments, hence it is necessary to establish a sufficient understanding of this disease. Limited number of studies have applied bibliometric methods to systematically analyze studies on post-stroke pain. This study aimed to systematically analyze scientific studies conducted worldwide on post-stroke pain from 2012 to 2021 to evaluate global trends in this field using a bibliometric analysis.
Publications related to post-stroke pain from 2012 to 2021 were obtained from the Web of Science Core Collection database. Bibliometrics Biblioshiny R-package software was used to analyze the relationship of publication year with country, institution, journals, authors, and keywords and to generate variant visual maps to show annual publications, most relevant countries, authors, sources, keywords, and top-cited articles.
In this study, 5484 papers met the inclusion criteria. The annual growth rate of publications was 5.13%. The USA had the highest number of publications (1381, 25.2%) and citations (36,395), and the University of Toronto had the highest number of papers (156, 2.8%). "Stroke", "management", "pain", "risk", "prevalence", "ischemic stroke", "risk factors", "disease", "diagnosis" and "therapy" are the top 10 keywords.
The global research interest regarding PSP has maintained growing over the past ten years. Both central post stroke pain and hemiplegic shoulder pain are the hottest research subjects. Further investigations are needed in order to reveal the mystery of the pathophysiologic mechanisms of CPSP, and high-quality well-designed trials of potential treatments of CPSP and HSP are also needed.
疼痛是卒中后患者最常见的症状之一。它是一种令人痛苦的体验，会影响患者的生活质量，在临床实践中非常普遍。卒中后疼痛（PSP）的发病机制尚不清楚，目前缺乏有效的药物治疗方法，因此有必要对这种疾病有充分的了解。仅有少数研究应用文献计量学方法系统分析了卒中后疼痛的研究。本研究旨在通过文献计量分析系统分析2012年至2021年全球范围内关于卒中后疼痛的科学研究，以评估该领域的全球趋势。
从科学引文索引核心合集数据库获取2012年至2021年与卒中后疼痛相关的出版物。使用文献计量学Biblioshiny R包软件分析出版年份与国家、机构、期刊、作者和关键词之间的关系，并生成各种可视化地图，以展示年度出版物、最相关的国家、作者、来源、关键词和被引频次最高 的文章。
在本研究中，5484篇论文符合纳入标准。出版物的年增长率为5.13%。美国的出版物数量最多（1381篇，占25.2%），被引频次最高（36395次），多伦多大学的论文数量最多（156篇，占2.8%）。“卒中”“管理”“疼痛”“风险”“患病率”“缺血性卒中”“危险因素”“疾病”“诊断”和“治疗”是排名前十的关键词。
在过去十年中，全球对PSP的研究兴趣持续增长。中枢性卒中后疼痛和偏瘫性肩痛都是最热门的研究课题。需要进一步研究以揭示中枢性卒中后疼痛病理生理机制的奥秘，还需要高质量、设计良好的中枢性卒中后疼痛和偏瘫性肩痛潜在治疗方法的试验。
