Article Synopsis
- The study compared the incidence of physical contacts, including head contacts and suspected injuries, between youth ringette and female ice hockey players during their 2021-2022 season in Alberta.
- Results showed that ringette players experienced significantly higher rates of body checking (2.6 times more) and head contacts (2 times more) than hockey players, along with a 3.4-fold increase in suspected injuries.
- Despite regulations prohibiting body checking and head contacts in both sports, very few instances were penalized, prompting a call for further research on different youth age groups.
Objectives: To examine factors associated with rates of game and practice-related concussion in youth ice hockey.
Design: Five-year prospective cohort (Safe2Play).
Setting: Community arenas (2013-2018).
Objectives: To evaluate prevention strategies, their unintended consequences and modifiable risk factors for sport-related concussion (SRC) and/or head impact risk.
Design: This systematic review and meta-analysis was registered on PROSPERO (CRD42019152982) and conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Data Sources: Eight databases (MEDLINE, CINAHL, APA PsycINFO, Cochrane (Systematic Review and Controlled Trails Registry), SPORTDiscus, EMBASE, ERIC0 were searched in October 2019 and updated in March 2022, and references searched from any identified systematic review.
Importance: Identifying research priorities of patients with concussion, their caregivers, and their clinicians is important to ensure future concussion research reflects the needs of those who will benefit from the research.
Objective: To prioritize concussion research questions from the perspectives of patients, caregivers, and clinicians.
Design, Setting, And Participants: This cross-sectional survey study used the standardized James Lind Alliance priority-setting partnership methods (2 online cross-sectional surveys and 1 virtual consensus workshop using modified Delphi and nominal group techniques).
Objective: Canada's national winter sport of ice hockey has high youth participation; however, research surrounding female ice hockey is limited and the injury burden remains high. This study compared rates of head contact (HC), body checking (BC; high-intensity player-to-player contact), and suspected concussion between female and male youth ice hockey.
Design: Cross-sectional.
Article Synopsis
- The study aimed to compare concussion rates and likelihood among young ice hockey players based on mouthguard use and helmet age.
- Players who wore mouthguards experienced a 28% lower concussion rate and 57% lower odds of concussion compared to those who did not.
- No significant differences were found in concussion rates or odds between newer and older helmets, suggesting mouthguards should be mandated to enhance safety in youth ice hockey.
Objective: To help address the high concussion burden in Canadian youth ice hockey, our primary objective was to examine the concurrent validity of youth ice hockey referees' ability to assess head contacts (HCs) and associated penalties using video analysis methods after implementation of the "zero tolerance for HC" policy by Hockey Canada.
Study Design: Cross-sectional study.
Participants: Certified Level II-III referees in Alberta, Canada.
Objective: Ringette and female ice hockey are high participation sports in Canada. Despite policies disallowing body checking, both sports have high injury and concussion rates. This study aimed to compare physical contact (PC), head contact (HC), and suspected injury and concussion incidence rates (IRs) in female varsity ringette and ice hockey.

Design: Cross-sectional survey.
Setting: Sledge hockey players, worldwide, across all levels of play.
Objective: The risk of concussion is high in Canadian youth ice hockey. Aiming to reduce this burden, in 2011, Hockey Canada implemented a national "zero tolerance for head contact (HC)" policy mandating the penalization of any player HC. In 2018 to 2020, Hockey Canada further amended this HC policy including stricter enforcement of severe HCs.

Design: Cohort video analysis study.
Setting: Ice hockey arenas in Calgary, Canada.
Background: To reduce the risk of concussion in youth ice hockey, Hockey Canada implemented a national "zero tolerance for head contact" (HC) policy in 2011. A previous cohort study revealed higher concussion rates after this implementation in players aged 11 to 14 years. However, it is unknown whether the elevated risk was due to higher HC rates or factors such as increased concussion awareness and reporting.
View Article and Find Full Text PDFBackground: Multiple evidence-based clinical practice guidelines (CPGs) exist to guide the management of concussion in children, but few have been translated into clinical pathways (CP), which operationalize guidelines into accessible and actionable algorithms that can be more readily implemented by health care providers. This study aimed to identify the clinical behaviours, attitudinal factors, and environmental contexts that potentially influence the implementation of a clinical pathway for pediatric concussion.
Methods: Semi-structured interviews were conducted from October 2017 to January 2018 with 42 emergency department clinicians (17 physicians, 25 nurses) at five urban emergency departments in Alberta, Canada.
Background: Most concussion studies have focused on the perspectives and expertise of health-care providers and caregivers. Very little qualitative research has been done, engaging the adolescents who have suffered concussion and continue to experience the consequences in their everyday life.
Objective: To understand the experiences of recovery from the perspective of adolescent patients of concussion and to present the findings through their voices.
Effects of Caffeine on Exertion, Skill Performance, and Physicality in Ice Hockey.
Int J Sports Physiol Perform
November 2019
Purpose: To determine the effects of low-dose caffeine supplementation (3 mg/kg body mass) consumed 1 h before the experiment on rating of perceived exertion (RPE), skills performance (SP), and physicality in male college ice hockey players.
Methods: Using a double-blind, placebo-controlled, randomized crossover experimental design, 15 college ice hockey players participated in SP trials and 14 participated in scrimmage (SC) trials on a total of 4 d, with prescribed ice hockey tasks occurring after a 1-h high-intensity practice. In the SP trials, time to complete and error rate for each drill of the validated Western Hockey League Combines Testing Standard were recorded.
Aim Or Objective: To examine the effectiveness of concussion prevention strategies in reducing concussion risk in sport.
Design: Systematic review according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines.
Data Sources: Eleven electronic databases searched and hand-search of references from selected studies.
