A Laboratory Study on the Ability of Head Kinematics to Predict Brain Strains in Helmeted Head ImpactsDownload
Sports and recreation are a leading cause of traumatic brain injury (TBI) in North America, accounting for nearly 30% of TBI cases in youth in Canada. Contact sports, such as hockey and football, put athletes at greater risk of suffering mild traumatic brain injuries (mTBI, such as concussion),...
A Laboratory Study on the Effect of Helmet Fit on Biomechanical Measures of Head and Neck Injury in Simulated ImpactDownload
Conventional wisdom and the language in international helmet testing and certification standards suggest that appropriate helmet fit and retention during an impact are important factors in protecting the helmet wearer from impact-induced injury. This thesis aims to investigate impact-induced...
An impact force transducer for anthropomorphic test dummy headforms: Application to study effects of external helmet accessories on biomechanical measures of head injury riskDownload
The first half of this thesis describes the mechanical design, calibration and validation of an in-fibre Bragg grating based impact transducer. The transducer comprises an in-fibre Bragg grating fixed to an aluminum superstructure (12 mm in diameter, 3 mm thickness) designed to withstand typical...
Hypoxic-ischemic brain damage (HIBD) is still of major concern in the neonatal period, resulting in chronic neurological sequelae stemming from damage to the term newborn brain. Full-body and focal-head cooling within 6 hours of birth have proven neuroprotective in human newborns and various...
