Relationship between brain injury criteria and brain strain across different types of head impacts can be different [PDF]
, 2020 Multiple brain injury criteria (BIC) are developed to quickly quantify brain injury risks after head impacts. These BIC originated from different types of head impacts (e.g., sports and car crashes) are widely used in risk evaluation. However, the accuracy of using the BIC on brain injury risk estimation across different types of head impacts has not ...

Electro-mechanical response of a 3D nerve bundle model to mechanical loads leading to axonal injury [PDF]
International Journal for Numerical Methods in Biomedical
Engineering, 34 (2018) e2942, 2020 Objective: Traumatic brain injuries and damage are major causes of death and disability. We propose a 3D fully coupled electro-mechanical model of a nerve bundle to investigate the electrophysiological impairments due to trauma at the cellular level. Methods: The coupling is based on a thermal analogy of the neural electrical activity by using the ...

Kinematics clustering enables head impact subtyping for better traumatic brain injury prediction [PDF]
, 2021 Traumatic brain injury can be caused by various types of head impacts. However, due to different kinematic characteristics, many brain injury risk estimation models are not generalizable across the variety of impacts that humans may sustain. The current definitions of head impact subtypes are based on impact sources (e.g., football, traffic accident ...

Mechanical strain to maxillary incisors during direct laryngoscopy
BMC Anesthesiology, 2017 Background While most Direct laryngoscopy leads to dental injury in 25–39% of cases. Dental injury occurs when the forces and impacts applied to the teeth exceed the ability of the structures to dissipate energy and stress.

Mechanical characterization of brain tissue in simple shear at dynamic strain rates [PDF]
Journal of the Mechanical Behavior of Biomedical Materials, 28
(2013) 71-85, 2020 During severe impact conditions, brain tissue experiences a rapid and complex deformation, which can be seen as a mixture of compression, tension and shear. Moreover, diffuse axonal injury (DAI) occurs in animals and humans when both the strains and strain rates exceed 10% and 10/s, respectively.

Predictive modelling of training loads and injury in Australian football [PDF]
, 2017 To investigate whether training load monitoring data could be used to predict injuries in elite Australian football players, data were collected from elite athletes over 3 seasons at an Australian football club. Loads were quantified using GPS devices, accelerometers and player perceived exertion ratings.
