- Description: Abstract: A retrospective case-series study of pedal- and motorcyclists presenting to a major metropolitan trauma centre over an 18 month period was undertaken. The injury data were coded according to a number of outcome variables, including intracranial injury of AIS severity >/= 2. Helmet use was coded. After stratification by rider type, data were analysed to examine the relationships between helmet use and injury using logistic regression. A total of 220 injured motorcycle riders and 137 injured pedal cyclists met the study's inclusion criteria, with 195 motorcycle riders and passengers (88.6%) and 87 pedal cyclists (63.5%) wearing helmets. Helmets were associated with a significant reduction (p<0.05) in the likelihood of head and intracranial injury in both rider groups. Associated with helmet use was a reduction in intracranial injury likelihood of 66% for both helmeted motorcycle riders and pedal cyclists. The study is further evidence of the benefits offered by helmets.

- Description: Sport-related head injuries place a significant burden on the health service delivery systems needed to treat and assess them; the sport delivery systems responsible for providing safe sporting opportunities; and personally on the individuals who sustain them. The number of head injury occurrences, the anecdotally high levels of public concern about the risk of head injury in sport and the fact that there is so much public misinformation about their assessment, management and prevention make the prevention of sport-related head injury a health priority. The most recent international consensus statement on the management of concussion in sport stated that there is a need to develop guidelines, education resources and other health promotion approaches for the prevention of head injury and its adverse outcomes across all sports with a risk of serious head injury.4 However, while there is evidence that some educational resources and guidelines have been developed, these have had varying success because they have not incorporated social marketing approaches.

- Description: The preliminary results of a prospective study ofmotorcycle crashes are reported. Motorcyclists were recruited from three major trauma centres in Sydney and through motorcycle organisations. The main sample criteria were that the cyclist crashed, and that they hit their head while wearing a helmet. Injury andnon-injury cases were collected. Case sampling occurred over a period of l8 months. The response rate through hospitals was approximately l4Yo for those meeting the selection criteria. All motorcyclists were interviewed and the helmets were examined. Characteristics such as environment (road type), vehicle (vehicle damage and interaction) and human factors were recorded. The location of helmet impacts and patterns of helmet damage were recorded. Injuries were documented and rated according to severity. The relationships between the crash characteristics, helmet use and injury will be presented.

- Description: BACKGROUND: Concussion is a serious problem in many contact sports, including rugby union football. The study's primary aim was to measure the efficacy of padded headgear in reducing the rates of head injury or concussion. METHODS: A cluster randomized controlled trial with three arms was conducted with rugby union football teams as the unit of randomization. Teams consisted of males participating in under 13-, 15-, 18-, and 20-yr age group competitions. The interventions were "standard" and "modified" padded headgear. Headgear wearing and injury were measured for each study team at each game over two seasons. RESULTS: Eighty-two teams participated in year 1 and 87 in year 2. A total of 1493 participants (10,040 player hours) were in the control group, 1128 participants (8170 player hours) were assigned to the standard headgear group, and 1474 participants (10,650 player hours) were assigned to the modified headgear group. The compliance rates were low in all groups, but 46% of participants wore standard headgear. An intention-to-treat analysis showed no differences in the rates of head injury or concussion between controls and headgear arms. Incidence rate ratios for standard headgear wearers referenced to controls were 0.95 and 1.02 for game and missed game injuries. Analyses of injury rates based on observed wearing patterns also showed no significant differences. Incidence rate ratios for standard headgear wearers referenced to nonwearers were 1.11 and 1.10 for game and missed game injuries. CONCLUSIONS: Padded headgear does not reduce the rate of head injury or concussion. The low compliance rates are a limitation. Although individuals may choose to wear padded headgear, the routine or mandatory use of protective headgear cannot be recommended. © 2009 by the American College of Sports Medicine.

- Description: OBJECTIVES: In this study, the incidence of head, neck and facial injuries in youth rugby was determined, and the associated risk factors were assessed. DESIGN: Data were extracted from a cluster randomised controlled trial of headgear with the football teams as the unit of randomisation. No effect was observed for headgear use on injury rates, and the data were pooled. SETTING: General school and club-based community competitive youth rugby in the 2002 and 2003 seasons. PARTICIPANTS: Young male rugby union football players participating in under-13, under 15, under 18 and under 21 years competitions. Eighty-two teams participated in year 1 and 87 in year 2. MAIN OUTCOME MEASURES: Injury rates for all body regions combined, head, neck and face calculated for game and missed game injuries. RESULTS: 554 head, face and neck injuries were recorded within a total of 28 902 h of rugby game exposure. Level of play and player position were related to injury risk. Younger players had the lowest rates of injury; forwards, especially the front row had the highest rate of neck injury; and inside backs had the highest rate of injuries causing the player to miss a game. Contact events, including the scrum and tackle, were the main events leading to injury. CONCLUSION: Injury prevention must focus on the tackle and scrum elements of a youth rugby game.

- Description: Objective: To describe trends in hospitalisation for sport-related concussion. Design, setting and patients: Analysis of routinely collected hospital admissions data from all Victorian hospitals (public and private) over the 2002-03 to 2010-11 financial years for patients aged ≥15 years with a diagnosis of concussion and an ICD-10-AM external cause activity code indicating sport. Main outcome measures: Number and cost of hospitalisations; rate of hospitalisation per 100000 participants overall and for specific sports; and percentage change in frequency and hospitalisation rate per 100000 participants over 9 years. Results: There were 4745 hospitalisations of people aged ≥15 years for sport-related concussion, with a total hospital treatment cost of $17944799. The frequency of hospitalisation increased by 60.5% (95% CI, 41.7%-77.3%) over the 9 years, but could only partially be explained by increases in sports participation, as the rate per 100000 participants also increased significantly, by 38.9% (95% CI, 17.5%-61.7%). After adjustment for participation, rates were highest for motor sports, equestrian activities, Australian football, rugby and roller sports. The greatest significant increases in rates were seen in roller sports, rugby, soccer and cycling. Conclusions: The frequency and participation-adjusted rate of hospitalisation for sport-related concussion, both overall and across several sports, increased significantly over the 9 years. These findings, along with high levels of public concern, make prevention of head injury in sport a population health priority in Australia.

- Description: Aim: The need for accurate diagnosis and appropriate return-to-play decisions following a concussion in sports has prompted the dissemination of guidelines to assist managing this condition. This study aimed to assess whether key messages within these guidelines are reflected in the knowledge of coaches and sports trainers involved in community sport. Methods: An online knowledge survey was widely promoted across Australia in May–August 2012 targeting community Australian Football (AF) and Rugby League (RL) coaches and sports trainers. 260 AF coaches, 161 AF sports trainers, 267 RL coaches and 228 RL sports trainers completed the survey. Knowledge scores were constructed from Likert scales and compared across football codes and respondent groups. Results: General concussion knowledge did not differ across codes but sports trainers had higher levels than did coaches. There were no significant differences in either concussion symptoms or concussion management knowledge across codes or team roles. Over 90% of respondents correctly identified five of the eight key signs or symptoms of concussion. Fewer than 50% recognised the increased risk of another concussion following an initial concussion. Most incorrectly believed or were uncertain that scans typically show damage to the brain after a concussion occurs. Fewer than 25% recognised, and >40% were uncertain that younger players typically take longer to recover from concussion than adults. Conclusions: The key messages from published concussion management guidelines have not reached community sports coaches and sports trainers. This needs to be redressed to maximise the safety of all of those involved in community sport.

- Description: Sports injuries are a significant clinical and public health concern. There is a growing call to improve the translation of available evidence-based and expert-informed sports injury prevention interventions into sustained use in practice by physicians and others (eg, athletic trainers, coaches, and parents) who care for injured athletes. This article provides a brief overview of the current sport injury prevention implementation literature before focusing specifically on the translation of guidelines (including consensus and position statements) developed to assist physicians and others diagnose and manage athletes with sport-related concussion and the associated return-to-play decisions. The outcomes of more than 20 published studies indicate that physician, athletic trainer, coach, parent, and athlete knowledge, use of, and compliance with sport-related concussion guidelines are limited. More concerted, coordinated, and theory-informed efforts are required to facilitate the widespread dissemination, translation, and implementation of such guidelines. An example is provided of how implementation drivers could be used to inform the development of a comprehensive, multilevel implementation strategy targeting the individual, organizational, and system-level changes necessary to support the translation of available sport-related concussion guidelines in both the clinical and sports settings.

- Description: AIM: Injuries are common in all professional football codes (including soccer, rugby league and union, American football, Gaelic Football and Australian football). The aim of the present study was to assess the potential effect that rule changes can have on injuries in professional football. METHODS: The Australian Football League (AFL) conducts an annual audit of injuries and makes regular rule changes on a semi-annual basis. An injury was defined as “any physical or medical condition that causes a player to miss a match in the regular season or finals” with ongoing records kept and publicly released over the decade 2004-2013. RESULTS: Over the ten years from 2004-2013, the AFL Commission made 26 rule changes, of which eight were considered to have potential impact on injury rates. The 2005 centre circle rule has significantly reduced rates of posterior cruciate ligament (PCL) injury in ruckmen. The rates of head and neck injuries dropped after initial rule changes, but rates of concussion and other head and neck injuries have increased since 2011, since a rule change that players could not re-enter the game after suffering concussion. Rates of hamstring and groin injuries have significantly fallen since the substitute rule was instituted in 2011, but rates of other lower limb injuries have risen over the same time period. CONCLUSION: Rule changes have, in some instances, had a beneficial effect on the rates of specific injuries over the last decade. However, the overall injury incidence in the AFL has not fallen, possibly because of a concurrent background increase in the speed of player movement across the decade. The AFL is in a fortunate position of being able to easily institute rule changes as it is the peak body of the sport which does not have to consider international competitions. The well established annual injury survey is able to monitor the effects of any rule changes on injury rates in a timely manner.

- Description: Objectives: Various definitions for concussion have been proposed, each having its strengths and weaknesses. We reviewed and compared current definitions and identified criteria necessary for an operational definition of sports-related concussion (SRC) in preparation of the 5th Concussion Consensus Conference (Berlin, Germany). We also assessed the role of biomechanical studies in informing an operational definition of SRC. Design: This is a systematic literature review. Data sources: Data sources include MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Clinical Trials and SPORT Discus (accessed 14 September 2016). Eligibility criteria for selecting studies: Eligibility criteria were studies reporting (clinical) criteria for diagnosing SRC and studies containing SRC impact data. Results: Out of 1601 articles screened, 36 studies were included (2.2%), 14 reported on criteria for SRC definitions and 22 on biomechanical aspects of concussions. Six different operational definitions focusing on clinical findings and their dynamics were identified. Biomechanical studies were obtained almost exclusively on American football players. Angular and linear head accelerations linked to clinically confirmed concussions demonstrated considerable individual variation. Summary/conclusions: SRC is a traumatic brain injury that is defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces with several common features that help define its nature. Limitations identified include that the current criteria for diagnosing SRC are clinically oriented and that there is no gold/standard to assess their diagnostic properties. A future, more valid definition of SRC would better identify concussed players by demonstrating high predictive positive/negative values. Currently, the use of helmet-based systems to study the biomechanics of SRC is limited to few collision sports. New approaches need to be developed to provide objective markers for SRC. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.
