Objectives: To investigate the accuracy and reliability of side-line video review of head impact events to aid identification of concussion in elite sport.
Design: Diagnostic accuracy and inter-rater agreement study.
Methods: Immediate care, match day and team doctors involved in the 2015 Rugby Union World Cup viewed 20 video clips showing broadcaster's footage of head impact events occurring during elite Rugby matches. Subjects subsequently recorded whether any criteria warranting permanent removal from play or medical room head injury assessment were present. The accuracy of these ratings were compared to consensus expert opinion by calculating mean sensitivity and specificity across raters. The reproducibility of doctor's decisions was additionally assessed using raw agreement and Gwets AC1 chance corrected agreement coefficient.
Results: Forty rugby medicine doctors were included in the study. Compared to the expert reference standard overall sensitivity and specificity of doctors decisions were 77.5% (95% CI 73.1-81.5%) and 53.3% (95% CI 48.2-58.2%) respectively. Overall there was raw agreement of 67.8% (95% CI 57.9-77.7%) between doctors across all video clips. Chance corrected Gwets AC1 agreement coefficient was 0.39 (95% CI 0.17-0.62), indicating fair agreement.
Conclusions: Rugby World Cup doctors' demonstrated moderate accuracy and fair reproducibility in head injury event decision making when assessing video clips of head impact events. The use of real-time video may improve the identification, decision making and management of concussion in elite sports.

Background: Growing concern surrounds the risk of neurodegenerative diseases in high-level collision sports, but research on Rugby Union's connection to these diseases is limited.
Objective: This study sought to examine the long-term neurodegenerative disease risk associated with participation in high-level Rugby Union ('rugby'), utilising whole-population administrative records.
Methods: This retrospective cohort study in New Zealand compared males born between 1920 and 1984 who were active in high-level (provincial or higher) rugby between 1950 and 2000 (n = 12,861) with males from the general population (n = 2,394,300), matched by age, ethnicity, and birthplace.

Objectives: To investigate whether sport-related concussion (SRC) history (including recency and total numbers) is associated with maximal isometric neck strength in elite Australian rules football (ARF) and rugby league (ARL) athletes.
Design: Cross-sectional cohort study.
Setting: Elite ARF and ARL environments.

The role of a sports mouthguard has been well established as one of protecting teeth from trauma particularly during contact sports. The aim of this study is to review the roles of sports mouthguard at both an elite and recreational level. From the history of the first mouthguards, to a modern custom-made mouthguard, the role of the mouthguard has expanded.

This study examined the prevalence of intentionally unreported and potentially unrecognized concussions in community rugby players and whether nondisclosure reasons vary by sex, position, or playing history. An online survey was completed by 1037 players (41.0% female; mean age 31.

Background: Concussions are mild traumatic brain injuries that often cause vision problems. They have significant impacts on everyday life, cognitive capacity, and sports performance, and may affect injury prevalence in fast contact sports such as ice hockey. A functional vision questionnaire specifically designed for sports was used here to study the correlation between vision problems and concussion history.
