Traumatic brain injury in contact sports
Traumatic brain injury (TBI) remains a major socioeconomic public health problem. Recently, there is heightened public awareness of brain injury in contact sports, which presents significant, unique challenges for effective clinical management. In this talk, we will illustrate how computational models of the human head could link important aspects of TBI, including sports-related concussion, for investigation. We will discuss a pre-computation strategy to achieve real-time estimation of brain tissue-level mechanical responses (vs. hours otherwise). We will then discuss potential avenues to further enhance the sophistication in brain injury analysis and improve injury prediction performance. Next, we will discuss how a sophisticated, yet efficient modeling scheme could enable future brain injury studies to focus on tissue responses from repetitive head impacts on an individual basis to identify a spectrum of concussive/sub-concussive injuries, as opposed to current approaches that largely rely on impact kinematics to predict a binary injury status on a population basis. Finally, we will show how these efforts could lead to an improved concussion management strategy in contact sports.
