Abstract—Concussions are among the most common injuries INTRODUCTION sustained by ice hockey goaltenders and can result from collisions, falls and puck impacts. However, ice hockey Goaltender masks were introduced into ice hockey goaltender helmet certification standards solely involve drop to reduce the risk of facial fracture.17 As technology tests to a rigid surface. This study examined how the design advanced, the goaltender mask evolved into a helmet/ characteristics of different ice hockey goaltender helmets affect head kinematics and brain strain for the three most cage combination, rather than a single piece full common impact events associated with concussion for fiberglass mask. Today, ice hockey goaltender helmets goaltenders. A NOCSAE headform was impacted under are typically made with a cage of carbon, steel, or conditions representing falls, puck impacts and shoulder titanium, a helmet shell of carbon and Kevlar com- collisions while wearing three different types of ice hockey posite, fiberglass, or polycarbonate and an energy ab- goaltender helmet models.
