| Abstract: | The purpose of this study was to investigate the extent to which ice hockey facial protectors can decrease overall head acceleration
during blunt impacts, as well as to identify whether attenuation differences exist between visors and cages. Commercial models
of three cages and three visors were assessed. Blunt impacts were simulated, permitting the measurement of peak accelerations
(PA) within the surrogate headform. Results indicated that face protectors, in combination with helmets, substantially reduced
PA during blunt impacts within threshold safety limits (below 300g). In general, cages showed lower PA than visors. Differences
between models were also observed during repeated impacts and impact site. In conclusion, this study demonstrates that facial
protectors function beyond their role in solely preventing facial injuries, complementing the role of the helmet in attenuating
head deceleration during impact. Consequently, the utilisation of facial protectors may reduce the severity and incidence
of head injuries. |
