Visual analysis of hot topics in concussion field by finite element method:Improvements in brain injury models,test methods and protective devices / 中国组织工程研究

ABSTRACT

BACKGROUND:Concussions caused by contact sports or traffic accidents are far more serious and common than people think,and have attracted widespread attention and high attention from the media,medical and sports circles in recent years. OBJECTIVE:To visualize the hot spots and trends in the field of concussion by using the method of bibliometrics,so as to provide some reference for the research in this field in China. METHODS:Based on the core collection database of Web of Science,the keyword retrieval strategy was(TS=(Concussion))AND TS=(Finite element).CiteSpace 6.2.R4 visualization tool was used to visually analyze the author,country,institution,keywords,cited documents,etc. RESULTS AND CONCLUSION:A total of 215 articles were included,with a general upward trend in the number of publications and citations.The distribution of disciplines involves biomedical engineering,biophysics,sports science,clinical neurology,neuroscience and other disciplines,showing a trend of interdisciplinary integration.The author with the most publications is Gilchrist M from University College Dublin,Ireland,the institution with the most publications is the University of Ottawa,and the country with the most publications is the United States.Key word analysis shows that the focus of research is on the establishment of brain injury models to simulate and predict concussion injuries;analysis of concussion injury mechanism;optimal design of protective equipment and devices.Through literature co-citation analysis,it is found that the prediction and evaluation of brain injury is the knowledge base and research hotspot in this field.The research hotspot of finite element application in the field of concussion injury mainly focuses on the prediction of head injury,combined with the exploration of brain injury mechanism and the design and improvement of protective equipment.With the progress of artificial intelligence and materials science,future research hotspots in the field of concussion injury will focus on the improvement of brain injury models,test methods and protective equipment.
