A multi-institutional research consortium dedicated to further understanding head impact exposure and concussion relationship between sports.

 

   It is difficult to predict how the brain of an athlete will respond to an impact during a sporting event. However multiple methods of analysis exist to further understand this response. One method is to perform experimental testing with cadavers, animals, and laboratory test surrogates. A second method is to use advanced mathematical modeling methods to predict the response of the brain. Generally this method is performed using Finite Element (FE) models. This project, funded by the National Operating Committee for Standards in Athletic Equipment (NOCSAE), is a novel effort to evaluate the role of FE brain models in the development of test methods for evaluating the effectiveness of sports equipment. To achieve this objective, we will initially model the response of the brain using impacts measured in the field that led to diagnosed concussion. We will then compare the models’ predictions with actual brain pathology, quantified with advanced neuroimaging shortly after the diagnosis of concussion.
