abstract="OBJECTIVE: The aim of this study was to analyze the concussion incidence rate ratios across 29 seasons in a Swedish Hockey League team. <br><br>DESIGN: Cohort study over 29 seasons within one Swedish elite series ice hockey team. PARTICIPANTS: All players who were part of one Swedish elite ice hockey team during the research period gave consent for participation in the study. INDEPENDENT VARIABLES: Exposure to top-level Swedish ice hockey. MAIN OUTCOME MEASURES: Incidence rate ratio for concussion and rehabilitation periods due to concussion were calculated and analyzed. <br><br>RESULTS: During the research period, 267 players in total were part of the team. A total of 1638 traumatic injuries were registered, of which 162 were concussions. Incidence rates (IRs) ranged from 0/1000 games during the first season to 118/1000 games for the final recorded season. The incidence rate ratio was 1.06 (confidence interval, 1.03-1.10) for the entire research period. A shift toward longer rehabilitation periods was discovered. <br><br>CONCLUSIONS: This study showed a significant increase of concussion IR and a trend toward longer rehabilitation periods due to concussion. Possible risk factors were discussed. Risk behavior and rehabilitation protocols should be prioritized areas in the research of concussion in ice hockey.<p /> <p>Language: en</p>",
