Biomechanical modelling of tissue stiffness following exposure to sub-concussive head trauma in collegiate athletes

In this project, we propose integrating well-known neuroimaging algorithms to model axonal integrity of the white matter over the course of a full season, in collegiate football players. Using these findings as a basis for further investigation, we intend to develop a novel imaging processing tool that will integrate information from different neuroimaging methods to model tissue strain, and highlight region-specific sensitivity of brain tissues to repetitive head trauma. This information will then be compared longitudinally over the course of a season, and contrasted across players based on their pattern of exposure to head trauma, characterized using helmet accelerometers and biomechanical analysis of impact properties. This novel multi-modal approach will allow our team to examine whether certain players are at higher risk for changes in tissue integrity, based on their exposure, in an effort to inform better coaching practices aimed at protecting athletes against head trauma, and promote safer playing fields.
