: Disorders of consciousness (DoC) is a dynamic and challenging discipline, presenting intriguing challenges to clinicians and neurorehabilitation specialists for the lack of reliable assessment methods and interventions. Understanding DoC keeps pace with scientific research is urgent to need. We quantitively analyzed publications on DoC over the recent 10 years via bibliometrics analysis, to summarize the intellectual structure, current research hotspots, and future research trends in the field of DoC. : Literature was obtained from the Science Citation Index Expanded of Web of Science Core Collection (WoSCC). To illustrate the knowledge structure of DoC, CiteSpace 5.8.R3 was used to conduct a co-occurrence analysis of countries, institutions, and keywords, and a co-citation analysis of references and journals. Also, Gephi 0.9.2 contributed to the author and co-cited author analysis. We found the most influential journals, authors, and countries and the most talked about keywords in the last decade of research. : A total of 1919 publications were collected. Over the past 10 years, the total number of annual publications has continued to increase, with the largest circulation in 2018. We found most DoC research and close cooperation originated from developed countries, e.g., the USA, Canada, and Italy. Academics from Belgium appear to have a strong presence in the field of DoC. The most influential journals were also mainly distributed in the USA and some European countries. : This bibliometric study sheds light on the knowledge architecture of DoC research over the past decade, reflecting current hotspots and emerging trends, and providing new insights for clinicians and academics interested in DoC. The hot issues in DoC were diagnosing and differentiating the level of consciousness, and detecting covert awareness in early severe brain-injured patients. New trends focus on exploring the recovery mechanism of DoC and neuromodulation techniques.
意识障碍（DoC）是一个动态且具有挑战性的领域，由于缺乏可靠的评估方法和干预措施，给临床医生和神经康复专家带来了有趣的挑战。了解意识障碍的最新研究进展迫在眉睫。我们通过文献计量学分析对近 10 年来关于意识障碍的出版物进行了定量分析，总结了意识障碍领域的知识结构、当前研究热点和未来研究趋势。
文献来源于 Web of Science 核心合集（WoSCC）中的科学引文索引扩展版（Science Citation Index Expanded）。为了说明意识障碍的知识结构，我们使用 CiteSpace 5.8.R3 对国家、机构和关键词进行共现分析，对参考文献和期刊进行共被引分析，还使用 Gephi 0.9.2 进行作者和共同被引作者分析。我们找到了过去 10 年研究中最有影响力的期刊、作者和国家，以及最热门的关键词。
共收集到 1919 篇出版物。在过去的 10 年中，每年的出版物总数持续增加，2018 年达到最大发行量。我们发现，大多数意识障碍研究和密切合作都源自发达国家，如美国、加拿大和意大利。比利时的学者似乎在意识障碍领域具有很强的影响力。最有影响力的期刊也主要分布在美国和一些欧洲国家。
这项文献计量研究揭示了过去 10 年意识障碍研究的知识结构，反映了当前的热点和新兴趋势，为对意识障碍感兴趣的临床医生和学者提供了新的见解。意识障碍的热点问题是诊断和区分意识水平，以及检测早期严重脑损伤患者的隐匿意识。新的趋势侧重于探索意识障碍的恢复机制和神经调节技术。
