Assessing Helmet Fit for Varsity Ice Hockey Athletes: A Field Intervention Study

Abstract

Background: Protective equipment is at the forefront of the discussion on reducing sports-related concussions, with the role of helmets being equivocal. Data suggest that modern helmets are not entirely protective against concussions, and ill-fitting helmets may contribute to concussions with longer-lasting symptoms. Helmet fit can be assessed via a checklist, but its application outside of youth sport is lacking. Objectives: The purpose of this study was to assess helmet fit and the effect of feedback for a men’s (n=22) and a women’s (n=20) university varsity ice hockey team across a season. Methods: This field intervention study used a 12-item helmet fit checklist which was divided into five categories, defining “proper fit” as meeting all criteria of the stability and size categories. Players’ concussion histories and helmet fit knowledge were assessed using a survey. Results: The number of properly fitting helmets for males increased from 23% to 77% over the season, while remaining consistent at 50% for females. For males, 73% had an increase in overall checklist scores and 27% saw no change; 45% of females had an increase, 5% saw no change, and 50% decreased. Reported female (85%) concussion rate was double that of males (41%), but perceived knowledge of helmet fit (male=36%, female=30%) and actual knowledge (male=77%, female=85%) were similar. Conclusions: Feedback only had a positive effect on helmet fit for males across the season, potentially due to helmet style differences for females. Improvements to checklist criteria and scoring would increase the effectiveness of assessing fit for multiple helmet styles.
