Brain strain and neck muscle dynamics during sagittal head impacts in naval scenarios
Abstract
Brain strain and neck muscle dynamics during sagittal head impacts in naval scenariosThe objective of this proposal is to determine the effect of neck muscle forces on brain strain during sagittalrotation of the head experienced in naval scenarios. Our long-term objective is to learn how to prevent closed head traumatic brain injury (TBI) using predictive models. Finite element (FE) models of the brainare increasingly able to predict the extent of biological trauma Musculoskeletal models of the body havebeen used to understand neck and other bodily injury. However, the interaction of the musculoskeletalsystem and the brain has not been studied in sagittal rotational head impacts. We will integrate a themusculoskeletal simulation platform, OpenSim, with a brain finite element model to test the central hypothesis that increasing neck muscle force increases brain strain by decelerating the head and exacerbating brain rebound in multiple naval scenarios.
