Supplementary file 1_Knowledge mapping and emerging trends in pediatric hemiplegia research: a bibliometric study spanning 1982–2025.docx

BackgroundPediatric hemiplegia is a significant neurological condition that impacts motor function and quality of life. This bibliometric analysis aimed to evaluate research trends, collaboration patterns, and emerging topics in pediatric hemiplegia research.
MethodsPublications were retrieved from the Web of Science Core Collection database spanning from 1982 to 2025. The analysis was conducted using VOSviewer, CiteSpace, and R-bibliometrix to examine contributions of countries, institutions, authors, journals, and keywords.
ResultsA total of 1,840 publications were analyzed, showing consistent growth with an annual growth rate of 8.69%. The United States emerged as the leading contributor with 393 publications, followed by Italy (137) and the United Kingdom (124), with strong international collaboration networks evident among 64 countries. The University of London demonstrated the highest institutional productivity with 142 publications, while Royal Children’s Hospital showed the strongest collaborative connections. Developmental Medicine and Child Neurology ranked as the most productive journal with 195 publications and highest citation impact. Boyd RN and Gordon AM were identified as the most influential authors based on h-index metrics and collaboration strength. Keyword analysis revealed five distinct research clusters, with “alternating hemiplegia,” “mutations,” “classification,” and “risk factors” emerging as current research hotspots since 2017.
ConclusionThis bibliometric analysis provides a comprehensive overview of research progress and identifies key hotspots in pediatric hemiplegia research, revealing the field’s evolution from basic clinical descriptions to advanced genetic and classification studies. These findings offer valuable insights for researchers and clinicians to understand current research priorities and guide future investigations in pediatric hemiplegia management and treatment strategies.

背景 儿童偏瘫（Pediatric hemiplegia）是一种影响运动功能与生活质量的重要神经系统疾病。本项文献计量分析（bibliometric analysis）旨在评估儿童偏瘫领域的研究趋势、合作模式与新兴研究主题。
方法 研究数据检索自1982年至2025年的Web of Science核心合集数据库（Web of Science Core Collection），采用VOSviewer、CiteSpace及R-bibliometrix工具开展分析，以考察国家、机构、作者、期刊及关键词的发文贡献情况。
结果 本研究共纳入1840篇文献进行分析，发文量呈持续增长趋势，年增长率达8.69%。美国以393篇文献成为核心贡献国，其次为意大利（137篇）与英国（124篇），64个国家间形成了紧密的国际合作网络。伦敦大学（University of London）的机构发文量最高，达142篇；而皇家儿童医院（Royal Children’s Hospital）的合作关联最为紧密。《发育医学与儿童神经病学（Developmental Medicine and Child Neurology）》期刊的发文量最高（195篇）且引用影响力最高。基于h指数（h-index）与合作强度指标，Boyd RN与Gordon AM为该领域最具影响力的作者。关键词分析共识别出5个独立的研究集群，其中“交替性偏瘫”“突变”“分类”及“危险因素”自2017年以来成为当前研究热点。
结论 本项文献计量分析全面梳理了儿童偏瘫领域的研究进展，明确了该领域的关键研究热点，揭示了该领域从基础临床描述向高级遗传学与分类学研究的演进历程。本研究结果可为研究者与临床医师理解当前研究重点、指导儿童偏瘫管理与治疗策略的未来研究提供有价值的参考依据。
