Helmets are the main form of head protection used in hockey. Concussions, however, still pose a significant health threat to hockey players. While researchers have used pneumatic impactors to simulate on-ice head impact injury mechanisms responsible for concussions, evidence of reliability and validity for the use of these impactors’ acceleration measures are needed to simulate head impact injuries accurately. The purpose of this study was to provide evidence of reliability and validity for the use of a new pneumatic helmet horizontal impact system to measure linear acceleration. The results provide evidence of reliability (ICC=.787-.875, p < .0001) and concurrent-related validity (ICC=.852-.949, p < .0001) when using the new impactor to measure linear acceleration applied to the headform. These outcomes suggest that the new impactor complies to the helmet testing standards.
