Research into sport-related concussion (SRC) has grown substantially over the past decade, yet no authors to date have synthesized developments over this critical time period.
To apply a network-analysis approach in evaluating trends in the SRC literature using a comprehensive search of original, peer-reviewed research articles involving human participants published between January 1, 2010, and December 15, 2019.
Narrative review.
MAIN OUTCOME MEASURE(S): Bibliometric maps were derived from a comprehensive search of all published, peer-reviewed SRC articles in the Web of Science database. A clustering algorithm was used to evaluate associations among journals, organizations or institutions, authors, and key words. The online search yielded 6130 articles, 528 journals, 7598 authors, 1966 organizations, and 3293 key words.
The analysis supported 5 thematic clusters of journals: (1) biomechanics/sports medicine (n = 15), (2) pediatrics/rehabilitation (n = 15), (3) neurotrauma/neurology/neurosurgery (n = 11), (4) general sports medicine (n = 11), and (5) neuropsychology (n = 7). The analysis identified 4 organizational clusters of hub institutions: (1) University of North Carolina (n = 19), (2) University of Toronto (n = 19), (3) University of Michigan (n = 11), and (4) University of Pittsburgh (n = 10). Network analysis revealed 8 clusters for SRC key words, each with a central topic area: (1) epidemiology (n = 14), (2) rehabilitation (n = 12), (3) biomechanics (n = 11), (4) imaging (n = 10), (5) assessment (n = 9), (6) mental health/chronic traumatic encephalopathy (n = 9), (7) neurocognition (n = 8), and (8) symptoms/impairments (n = 5).
The findings suggest that during the past decade SRC research has (1) been published primarily in sports medicine, pediatric, and neuro-focused journals, (2) involved a select group of researchers from several key institutions, and (3) concentrated on new topical areas, including treatment or rehabilitation and mental health.
在过去十年中，与运动相关的脑震荡（SRC）研究有了显著增长，但迄今为止，尚无作者对这一关键时期的研究进展进行综合分析。
采用网络分析方法，通过全面检索2010年1月1日至2019年12月15日期间发表的涉及人类参与者的原创性、同行评审研究文章，评估SRC文献的发展趋势。
叙述性综述。
通过全面检索科学网数据库中所有已发表的、同行评审的SRC文章，得出文献计量图。使用聚类算法评估期刊、组织或机构、作者和关键词之间的关联。在线搜索共得到6130篇文章、528种期刊、7598位作者、1966个组织和3293个关键词。
分析支持了5个期刊主题聚类：（1）生物力学/运动医学（n = 15），（2）儿科学/康复（n = 15），（3）神经创伤/神经病学/神经外科（n = 11），（4）普通运动医学（n = 11），以及（5）神经心理学（n = 7）。分析确定了4个核心机构的组织聚类：（1）北卡罗来纳大学（n = 19），（2）多伦多大学（n = 19），（3）密歇根大学（n = 11），以及（4）匹兹堡大学（n = 10）。网络分析揭示了SRC关键词的8个聚类，每个聚类都有一个核心主题领域：（1）流行病学（n = 14），（2）康复（n = 12），（3）生物力学（n = 11），（4）影像学（n = 10），（5）评估（n = 9），（6）心理健康/慢性创伤性脑病（n = 9），（7）神经认知（n = 8），以及（8）症状/损伤（n = 5）。
研究结果表明，在过去十年中，SRC研究（1）主要发表在运动医学、儿科学和神经科学领域的期刊上，（2）涉及来自几个关键机构的特定研究人员群体，（3）集中在新的主题领域，包括治疗或康复以及心理健康。
