Abstract
INTRODUCTION Traumatic brain injury in sport continues to be at the top of the list of injuries responsible for more lost days to injury then trauma to any other region of the body. The National Football and National Hockey Leagues have both identified head trauma as the most serious injury in their respective sports. Head trauma is often followed by life long and serious injuries or ill defined and unpredictable prognosis in the case of concussion making prevention the most effective approach to managing these injuries. Helmets are a primary tool to prevent or mitigate head injures in sport. Historically, helmets have employed vinyl nitrile and expanded polystyrene and expanded polyethylene foams to attenuate impact energy during impacts (Cusimano, 2003). This research project was designed to evaluate the effectiveness of helmets using engineered chambers to attenuate impact acceleration during impact.
