Network Analysis of Sport-Related Concussion Research During the Past Decade (2010-2019)

Trends and hotspots in research of traumatic brain injury from 2000 to 2022: A bibliometric study

Traumatic brain injury (TBI) is a major health concern globally, which is characterized by high morbidity and mortality rates. Since the 21st century, TBI has received increasing attention and the number of publications is growing rapidly. This study aimed to characterize the volume and quality of scholarly output on TBI and identify the most impactful literature, research trends, and hotspots from the year 2000-2022. We searched publications on TBI through the Web of Science Core Collection-Science Citation Index Expanded database which were published from 2000 to 2022. Basic information of each paper, including publication year, countries, authors, affiliations, journal, fundings, subject areas, and keywords were collected for further analysis by using Microsoft Excel, VOSviewer, and CiteSpace software. A total of 47231 TBI-related publications were identified through database retrieval. The annual number of publications on TBI has increased steadily over the past twenty years and the number in the year 2022 is sevenfold higher than that in 2000. The United States of America (USA) was the leading country in both numbers of publications and citations, which is consistent with the finding that it had the most funding agencies. Menon DK was the author with the highest influence and the University of California System was the most productive affiliation. Moreover, keywords analysis suggested that the research topics can be mainly divided into six categories: management, rehabilitation, mechanisms, concussion, neuroimaging, and neuroendocrine. This study visualized the trends and focuses of scientific research related to TBI, both quantitatively and qualitatively. The USA had a relatively high academic impact owing to its productive experts and institutions in this field. Neuroinflammation, machine learning, tranexamic acid, and extracellular vesicles are currently hot topics in the field of TBI.

Sports Medicine: Scientometric of 10 Years of Global Scientific Productions

Background

Sport Medicine maintains an active lifestyle and reduces or inhibits countless age-related changes in physical and physiological function by substituting sports methods for people. Improving the scientific situation in sports medicine over time will lead to progress in the field of prevention and reduction of mortality. This study aimed to analyze sports medicine research in the world in terms of scientometric indicators using the Scopus database.

Methods

This is a bibilometric study. The study population consisted of all articles indexed in the Scopus citation database in the field of sports medicine, registered by researchers from 2011 to 2020. They used SciVal analytical tool as a bibliometric tool that allows the analysis of publications in various parameters, and VOSviewer and Excel software as drawing all citation maps.

Results

The highest increase in scientific production of sports medicine was in 2015. Overall, 1,695 articles were published, which received an average of 13 citations per article. The highest rate of scientific production is related to the United States with 41%, followed by the United Kingdom with 16% and Australia with 9%, with a significant difference in the second and third which indicates the high quality and impact of this group of studies. The British Journal of Sports Medicine has contributed the most to the publication of highly cited articles. The most commonly used terms include "Head Impact", "Athletes", and "Sport Injury".

Conclusion

Considering the importance of sports medicine in the prevention, control and treatment of many diseases, as well as the growth of the elderly population, it is necessary to develop research in this area. By identifying the features of highly cited articles in this field, a clear view of the top authors and publications and widely used topics was provided.
