- Description: Objectives: Youth rugby union is a popular sport with a high injury incidence density (IID) and burden. This high risk has called for further research into the factors affecting the injuries in youth rugby. The aim of the study was to analyse time-loss IID and burden in multiple schoolboy rugby teams over a season and the potential factors associated with injury. Design: Prospective cohort Methods: All time-loss injuries were recorded from three schools for the whole season. Overall IID and injury burden were calculated, as well as for injury event, type, location and the match quarter in which they occurred and Poisson regression analyses were performed to determine differences. Results: IID was 28.8 (18.9–38.6) injuries per 1000 player hours over the season, with an injury burden of 379.2 (343.6–414.9) days lost per 1000 player hours. The ball-carrier had a significantly higher IID (11.3 (5.2–17.5) per 1000 player hours) compared to other events, and the joint (non-bone)/ligament injuries were the most common (IID of 12.2 (5.8–18.6) per 1000 player hours) and severe type of injury (burden of 172.6 (148.5–196.6) days lost per 1000 player hours). Conclusions: The IID was similar to previous youth rugby studies, however the injury burden was much lower. The South African youth cohort showed similar factors associated with injury for inciting event (the tackle) and injury type (joint (non-bone)/ligament) and location (lower limb) as seen in other studies in both youth and senior players.

- Description: OBJECTIVE:: To determine if baseline Sport Concussion Assessment Tool, third Edition (SCAT3) scores differ between athletes with and without disability. DESIGN:: Cross-sectional comparison of preseason baseline SCAT3 scores for a range of England international footballers. SETTING:: Team doctors and physiotherapists supporting England football teams recorded playersʼ SCAT 3 baseline tests from August 1, 2013 to July 31, 2014. PARTICIPANTS:: A convenience sample of 249 England footballers, of whom 185 were players without disability (male: 119; female: 66) and 64 were players with disability (male learning disability: 17; male cerebral palsy: 28; male blind: 10; female deaf: 9). ASSESSMENT AND OUTCOME MEASURES:: Between-group comparisons of median SCAT3 total and section scores were made using nonparametric Mann–Whitney–Wilcoxon ranked-sum test. MAIN RESULTS:: All footballers with disability scored higher symptom severity scores compared with male players without disability. Male footballers with learning disability demonstrated no significant difference in the total number of symptoms, but recorded significantly lower scores on immediate memory and delayed recall compared with male players without disability. Male blind footballersʼ scored significantly higher for total concentration and delayed recall, and male footballers with cerebral palsy scored significantly higher on balance testing and immediate memory, when compared with male players without disability. Female footballers with deafness scored significantly higher for total concentration and balance testing than female footballers without disability. CONCLUSIONS:: This study suggests that significant differences exist between SCAT3 baseline section scores for footballers with and without disability. Concussion consensus guidelines should recognize these differences and produce guidelines that are specific for the growing number of athletes living with disability.
