Research has estimated that between 1.6 and 3.8 million sports-related concussions are sustained in the United States each year [1]. In light of new research suggesting that potential long-term neurodegenerative effects can result from repetitive brain injuries, concussions have been placed under the national spotlight as a primary health concern. While minimizing the exposure of athletes to head impact is one important component of reducing the incidence of concussion, improvement in head protection is another essential element. This paper focuses on a new mechanism to evaluate the protective capabilities of helmets in relation to concussion.
