Sports-related eye injuries: floorball endangers the eyes of young players

The objectives of this study were to determine the distribution of different sports-related eye injuries and to identify injury types to enable recommendations to be made about the use of protective eyewear. The study population comprises all 565 eye trauma patients examined at the Ophthalmology Emergency Clinic of the Helsinki University Central Hospital over a 6-month period. Data were collected from patient histories and questionnaires. In addition, three severe floorball eye injury cases are presented. Of the 565 eye traumas, 94 (17%) were sports related. Of these, 42 (45%) were associated with floorball. Countrywide, in Finland, estimated over 300 (+95% CI 228-415) floorball eye injuries occur annually. The mean age of floorball patients was 22 years. The most common finding (55%) in sports injury patients was hyphema. Clinically severe eye injuries during this period accounted for one-fourth of all cases. During the study period, no eye injury was found in an organized junior ice hockey, where facial protection is mandatory. Floorball is estimated to belong to the highest risk group in sports, and thus, the use of protective eyewear is strongly recommended. We conclude that national floorball federations should make protective eyewear mandatory.     

Injuries in Swedish floorball: a cost analysis

The epidemiology of sport injuries is well documented. However, the costs are rarely discussed. Previous studies have presented such costs in specific sports or localization. No study has investigated the costs related to injuries in elite floorball. Thus, the aim of this study was to estimate cost of injuries in Swedish elite floorball players. During 1 year, 346 floorball players were prospectively followed. All time‐loss injures were recorded. The injured players were asked to complete a questionnaire regarding their costs tied to the injury. Mean costs were calculated by multiplying the total resource use with the collected unit costs and dividing these total costs with the number of injuries as well as players. The results showed that the average cost per injury increased with the level of severity and ranged from 332 to 2358 Euros. The mild and moderate overuse injuries were costlier than the corresponding traumatic injuries. However, the severe traumatic injuries were associated with higher costs than overuse injuries. Knee injuries were the costliest. Our results indicate that there are costs to be saved, if floorball injuries can be avoided. They should be of interest to decision makers deciding whether to invest in preventive interventions.     

Incidence and severity of reported acute sports injuries in 35 sports using insurance registry data

Acute injuries in sport are still a problem where limited knowledge of incidence and severity in different sports at national level exists. In Sweden, 80% of the sports federations have their mandatory injury insurance for all athletes in the same insurance company and injury data are systematically kept in a national database. The aim of the study was to identify high‐risk sports with respect to incidence of acute and severe injuries in 35 sports reported to the database. The number and incidences of injuries as well as injuries leading to permanent medical impairment (PMI) were calculated during 2008–2011. Each year approximately 12 000 injuries and 1 162 660 licensed athletes were eligible for analysis. Eighty‐five percent of the injuries were reported in football, ice hockey, floorball, and handball. The highest injury incidence as well as PMI was in motorcycle, handball, skating, and ice hockey. Females had higher risk of a PMI compared with males in automobile sport, handball, floorball, and football. High‐risk sports with numerous injuries and high incidence of PMI injuries were motorcycle, handball, ice hockey, football, floorball, and automobile sports. Thus, these sports ought to be the target of preventive actions at national level.     

Ocular sports injuries: the current picture

Objectives—To determine the recent incidence of eye injury due to sport in Scotland, identify any trend, and establish which sports are responsible for most injury? The type of injury and final visual outcome is also evaluated. Methods—A prospective observational study of ocular injuries sustained during sport was performed over a one year period. Only patients requiring hospital admission were included. Data were collected on a standardised proforma and entered into a central database. Patients were followed up for at least three months. Results—Of 416 patients admitted because of ocular injury, 52 (12.5%) resulted from playing a sport. Although all racquet sports together accounted for 47.5% of these injuries, football was the single most common sport associated with ocular trauma, being responsible for 32.5% of cases. The most common clinical finding was macroscopic hyphaema occurring in 87.5% of patients. Overall the final visual acuity was 6/6 in 92.5% of patients. Conclusions—The incidence of eye injury due to sport at 12.5% is lower than previously reported, suggesting a change in the pattern of ocular trauma. Football is the single most common cause of ocular injury from sport in Scotland, but the wearing of protective headgear would be difficult to instigate. The incidence of hyphaema in sport related ocular trauma (87.5%) is almost double that of all ocular injury (47.8%), so the potential for serious visual loss as the result of a sports injury should not be underrated. Ophthalmologists have a role in protecting this young population at risk by actively encouraging the design and use of protective eyewear. Key Words: eye injury; ocular trauma; hyphaema; protective eyewear     

Eye injuries in sports

In a retrospective study from 1988 to 1998, eye injuries were found in 553 patients. Seventy-six (13.7%) of these injuries were associated with sport. The mechanism of trauma was for the most part a ball (71.1%) or a club (13.2%). Most eye injuries occurred in soccer (35.5%), which is, by far, the most widespread sport in this region of Norway. A disproportionately high number of the injuries occurred in floorball (17.1%), bandy (13.2%), and squash (10.5%). The rules in these sports may, in theory, be strict enough to prevent eye injuries in most cases. However, these rules are often neglected in informal activities. Strategies for educating the general public about the potentially serious effect of eye injuries in sports exposed to such risk are of great importance.     

Sports injuries in physical education teacher education students

Sports injuries could be highly detrimental to the career of a physical education teacher education (PETE) student. To enable the development of future sports injury prevention programs, sports injuries in 128 first‐year academic bachelor PETE students were registered prospectively during one academic year. Common risk factors for sports injuries, taken from the literature, were also evaluated by means of logistic regression analysis. We found an incidence rate of 1.91 and an injury risk of 0.85, which is higher than generally found in a sports‐active population. Most injuries involved the lower extremities, were acute, newly occurring injuries, and took place in non‐contact situations. More than half of all injuries lead to an inactivity period of 1 week or more and over 80% of all injuries required medical attention. A major part of these injuries happened during the intracurricular sports classes. Few differences were seen between women and men. A history of injury was a significant risk factor (P = 0.018) for the occurrence of injuries, and performance of cooling‐down exercises was significantly related to a lower occurrence of ankle injuries (P = 0.031). These data can inform future programs for the prevention of sports injuries in PETE students.     

The 9+ screening test score does not predict injuries in elite floorball players

We aimed to examine whether the 9+ screening test score could predict injuries in elite floorball players. Eighty-four elite floorball players participated in the study. At baseline, two physiotherapists assessed the participants using the 9+ screening test. The test score reflects strength, stability, mobility, and functional movement pattern with an emphasis on the lower body and core. Injuries that occurred the following season (2013/2014) were recorded by medical staff, coaches, and/or self-reported by the players. Overall, there was no relationship between the 9+ screening test score and injury risk (OR = 0.96 per SD lower test score, P = .84). We, therefore, conclude that the 9+ screening test is not suited for overall injury risk prediction in elite floorball players. Whether the test may be used to predict risk of certain injury types more strongly related to inadequate mobility and strength (eg, muscle ruptures or strains) warrants further investigation.     

Incidence and body location of reported acute sport injuries in seven sports using a national insurance database

Sports with high numbers of athletes and acute injuries are an important target for preventive actions at a national level. Both for the health of the athlete and to reduce costs associated with injury. The aim of this study was to identify injuries where injury prevention should focus, in order to have major impact on decreasing acute injury rates at a national level. All athletes in the seven investigated sport federations (automobile sports, basketball, floorball, football (soccer), handball, ice hockey, and motor sports) were insured by the same insurance company. Using this insurance database, the incidence and proportion of acute injuries, and injuries leading to permanent medical impairment (PMI), at each body location, was calculated. Comparisons were made between sports, sex, and age. In total, there were 84 754 registered injuries during the study period (year 2006‐2013). Athletes in team sports, except in male ice hockey, had the highest risk to sustain an injury and PMI in the lower limb. Females had higher risk of injury and PMI in the lower limb compared to males, in all sports except in ice hockey. This study recommends that injury prevention at national level should particularly focus on lower limb injuries. In ice hockey and motor sports, head/neck and upper limb injuries also need attention.     

Training and match volume and injury in adolescents playing multiple contact team sports: A prospective cohort study

Training and competition loads have emerged as valuable injury risk factors but very few studies have explored injury outcomes in adolescent athletes. The aims of this study were to describe injuries and to explore the relationship between training and match load volumes and injury in adolescent athletes participating in multiple contact team sports. One hundred and three male youth rugby athletes aged 14‐16 years from 8 rugby union teams were prospectively monitored during a season for weekly training and match volumes and injuries. The relationship between volume and injury was explored by comparing the weekly volume in the week prior to an injury vs weeks without injury. There were 83 time‐loss injuries in 58 athletes (62%). Overall injury incidence was 18.5 per 1000 player‐hours. Mean weekly injury prevalence was 27% (95% CI 25‐30). Average weekly volume was 5.4 (2.2) hours comprising 1.4 (1) match hours and 4 (2.6) training hours. Compared with weeks without injury, weeks prior to an injury had higher match volumes (110 [57] min vs 83 [59] min, P < 0.001). Poisson regression demonstrated that match volume was a predictor of injury with an odds ratio of 1.41 (P = 0.001). The contribution of match volumes to injury risk and the relatively high injury burden in these athletes may be profound. Very high match volumes are unlikely to be in the best interests of young athletes and could be avoided with a systematic approach to load management and athlete development.     

Epidemiology of physical activity‐related injuries in Chinese university students

Knowledge gaps of the physical activity‐related injury (PARI) problem among general undergraduates exist. We conducted a study in four universities, where 1421 students graded 1‐3 were interviewed face‐to‐face during April and May after their completion of the baseline survey in March and April 2017, aiming to describe the incidence and characteristics of PARI. PARI experience and physical activity (PA) participation in the past 12 months were collected. Injury incidence density (IID) and risk, and injury characteristics were evaluated for the overall sample and by gender. Pearson chi‐square or Fisher's exact tests and independent‐sample t tests were used to test between‐group differences. We found that 486 PARIs were reported totally by 289 participants , with an overall IID of 0.57 per 1000 hours of exposure (males: 1.07, females: 0.45) and an injury risk of 0.34 injuries/student/y (males: 0.52; females: 0.28) . Higher IIDs were found in roller skating, football, and basketball. The majority of injuries occurred outdoors and involved the lower extremities, with sprain and strain being the primary injury types. Moreover, most injuries were new, acute, and happened in non‐contact situations. Of all injuries, 52.1% required medical attention and 64.6% resulted in inactivity of one or more days. Some significant differences were observed between males and females. Our study indicates that PARI is a public health concern among Chinese university students, which can provide direction for targeted prophylactic interventions to underpin the sex‐specific injury mechanism to reduce PARI.     

Unprotected eyes in squash: not seeing the risk of injury

The use of appropriate eyewear in squash can protect the eyes against injury. However, few adult squash players adequately protect their eyes against potential severe injuries. We describe the characteristics of non-users of protective eyewear and examine predictors of appropriate eyewear use. Self-report surveys of adult players were conducted in metropolitan Melbourne, Australia. Information on players' knowledge, behaviours and attitudes associated with protective eyewear use was collected, in addition to player demographic data. Appropriate eyewear was defined as Standards-approved polycarbonate lens eyewear. The majority 92.2% of players did not adequately protect their eyes while playing squash. Significant predictors of reported eyewear use were: previous eye injury: playing squash on average more than 2 hr per wk: having played for more than 20 y; and having more favourable attitudes towards eye safety in squash. The significant predictors of appropriate eyewear use were: being female; previous eye injury; playing squash on average more than 2 hr per week; and having more favourable attitudes towards eye safety in squash. Understanding the characteristics of both users and non-users of appropriate eye protection in squash is essential for informing future prevention strategies.     

Protective eyewear promotion: applying principles of behaviour change in the design of a squash injury prevention programme

Eye injuries in squash have the potential to be severe. Although these injuries can be prevented through the use of protective eyewear, few players wear such eyewear. The aim of this paper is to outline the behavioural principles guiding the design of a squash eyewear promotion initiative, the Protective Eyewear Promotion (PEP). Ecological principles of behaviour change were used to provide a comprehensive perspective on intrapersonal factors, policies and physical environmental influences of protective eyewear use. Results of baseline player surveys and venue manager interviews were used to provide relevant and specific intervention content. At baseline, protective eyewear was not found to be readily available, and players' behaviours, knowledge and attitudes did not favour its use. The main components of PEP involved informing and educating both players and squash venue operators of the risk of eye injury and of appropriate protective eyewear, as well as assisting with the availability of the eyewear and offering incentives for players to use it. A structural strength of PEP was the strong collaborative links with the researchers of different disciplines, the squash governing body, eyewear manufacturers, squash venue personnel, as well as players. Attempts were made within the project structure to make provision for the future dissemination and sustainability of more widespread eye injury prevention measures in the sport of squash.     

Incidence, nature and causes of floorball injuries

During 1990 and 1991, 9% of all sports injuries that required emergency care at the University Hospital of Umeå were caused by floorball. Seventy-eight per cent of the injuries were minor (AIS 1) and 21% were moderate (AIS 2). Sprains of the ankle and knee joints were most frequent, constituting 30% and 11% of all injuries, respectively. Licensed players were affected in 14% of all floorball injuries, and 61% of these injuries occurred during a game. We found no difference in severity or type of injuries between licensed players and recreational players. Our data show that the number of floorball injuries is increasing and that the majority of these injuries are of minor severity.     

Safety of third‐generation artificial turf in male elite professional soccer players in Italian major league

Our hypothesis is that there are no difference in the injury incidence on artificial turf and natural grass. During the 2011/2012 season, we recorded injuries which occurred to two Italian stadiums equipped with third‐generation artificial turf during 36 games (391 players). Data were compared with the injuries which occurred in the same season in two stadiums equipped with natural grass (372 players). We recorded 43 injuries during the playing time (16.7 per 1000 h). About 23 (18.1 per 1000 h) injuries occurred on artificial turf, while 20 (15.2 per 1000 h) on the natural grass with no statistical differences P > 0.05. We recorded 10 (7.87 per 1000 h) contact and 13 (10.23 per 1000 h) non‐contact injuries on artificial turf, while 5 (3.8 per 1000 h) contact and 15 (11.4 per 1000 h) non‐contact injuries on natural grass P > 0.05. The overall relative risk was 1.15; 95% CI: 0.64–2.07). Our study demonstrates a substantial equivalence in injury risk on natural grass and artificial turf in elite professional soccer athletes during official matches.     

A prospective study of injuries in licensed floorball players

Injuries occuring among 457 licensed floorball players in teh Swedish National League were analysed prospectively during the season from 1993 to 1994. Fifty-one (11%) players sustained 58 injuries. The majority (76%) of the injuries were due to trauma mostly during the game (55%). Twenty-three (52%) of the traumatic injuries were caused by an opponent or a stick. Ankle sprain (35%) was the most common diagnosis. Injury severity classified with regard to time of absence from sport participation were similarly distributed for minor (36%), moderate (29%) and major (35%) injuries. The total rate of injury was 2.5 per 1000 hours for female and 2.6 for male players. Although this rate is lower than for contact sports like soccer and ice-hockey, we feel that further investigation of floorball injuries and improvement of protection devices would be valuable.     

Nonelite exercise‐related injuries: Participant reported frequency,management and perceptions of their consequences

This mixed methods study explored the frequency of sport/exercise‐related injuries in nonelite sport, participant‐reported management and perceptions of potential injury consequences. Focus group participants, who trained two to four times a week and had previously sustained musculoskeletal sports‐related injuries, reported seeking medical advice secondary to advice from teammates or online research. General practitioners were viewed as gatekeepers to specialist secondary care and less able to effectively treat sport‐related injuries. Participants displayed limited awareness of potential future implications of injury, and considered physical and psychological benefits of exercise more valuable than potential injury‐associated risks. In the survey of physically active people, over half reported sustaining an exercise‐related injury (562/1002, 56%). Previously injured respondents were less likely to consider consulting a health professional for injury‐related advice than those with no injury history (45% vs 64%; P < 0.001) and more likely to continue exercising despite injury (51% vs 37%; P < 0.001). Concerns about injuries largely related to short‐term issues; only 32% were concerned about possible long‐term joint problems including osteoarthritis. Exercise‐related injury was common in nonelite exercise participants. There was some dissatisfaction with care pathways for sports‐related injuries and a lack of awareness about appropriate injury management and potential consequences of injury, particularly in the long‐term.     

Altered hip control during a standing knee-lift test is associated with increased risk of knee injuries

A few prospective studies have investigated hip and pelvic control as a risk factor for lower extremity (LE) injuries. The purpose of this study was to investigate whether deficits in hip and lumbopelvic control during standing knee-lift test are associated with increased risk of acute knee and LE injuries in youth team sports. At baseline, 258 basketball and floorball players (aged 12-21 years) participated in a standing knee-lift test using 3-dimensional motion analysis. Two trials per leg were recorded from each participant. Peak sagittal plane pelvic tilt and frontal plane pelvic drop/hike were measured. Both continuous and categorical variables were analyzed. New non-contact LE injuries, and match and training exposure, were recorded for 12 months. Seventy acute LE injuries were registered. Of these, 17 were knee injuries (eight ACL ruptures) and 35 ankle injuries. Risk factor analyses showed that increased contralateral pelvic hike was significantly associated with knee injury risk when using categorical variable (HR for high vs low group 4.07; 95% CI 1.32-12.6). Furthermore, significant association was found between high lateral pelvic hike angles and ACL injury risk in female players (HR for high vs low group 9.10; 95% CI 1.10-75.2). Poor combined sensitivity and specificity of the test was observed. In conclusion, increased contralateral pelvic hike is associated with non-contact knee injury risk among young team sport players and non-contact ACL injuries among female players. More research to determine the role of pelvic control as a risk factor for knee injuries is needed.     

High ankle injury rate in adolescent basketball: A 3‐year prospective follow‐up study

This prospective study investigated the incidence and pattern of acute time‐loss injuries in young female and male basketball players. Eight basketball teams (n=201; mean age 14.85±1.5) participated in the follow‐up study (2011‐2014). The coaches recorded player participation in practices and games on a team diary. A study physician contacted the teams once a week to check new injuries and interviewed the injured players. In total, 158 injuries occurred. The overall rate of injury (per 1000 hours) was 2.64 (95% CI 2.23‐3.05). Injury rate was 34.47 (95% CI 26.59‐42.34) in basketball games and 1.51 (95% CI 1.19‐1.82) in team practices. Incidence rate ratio (IRR) between game and practice was 22.87 (95% CI 16.71‐31.29). Seventy‐eight percent of the injuries affected the lower limbs. The ankle (48%) and knee (15%) were the most commonly injured body sites. The majority of injuries involved joint or ligaments (67%). Twenty‐three percent of the injuries were severe causing more than 28 days absence from sports. Number of recurrent injuries was high (28% of all injuries), and most of them were ankle sprains (35 of 44, 79%). No significant differences were found in injury rates between females and males during games (IRR 0.88, 0.55, to 1.40) and practices (IRR 1.06, 0.69, to 1.62). In conclusion, ankle and knee ligament injuries were the most common injuries in this study. Moreover, the rate of recurrent ankle sprains was alarming.     

A 1‐year prospective analysis of injuries in amateur and elite fistball

The purpose of this study was to examine the incidence and mechanisms of acute injuries in the sport of fistball. No scientific studies on injury characteristics have yet been conducted in this traditional sport game. The study was conducted prospectively over the course of 12 months. During a total of 40.308 h of sport‐specific exposure, 240 players reported 492 injuries, representing an overall injury rate of 12.2 injuries/1000 h of exposure. Most injuries were classified as bagatelle injuries (67.8%). The majority of the injuries were located in the knee (23.5%) followed by the elbow (11.9%) and the hip (11.5%). Ankle injuries resulted in the longest impairment from sports participation. The most common types of injury were abrasions (38.2%), contusions (21.1%), distortions (7.5%) and muscle strains (6.9%). Wrong or insufficient equipment (15.0%) was the most commonly mentioned causes of injury. The data indicate that the injury risk in fistball is rather high; however, the sport should not be considered a high‐risk sport because most of the injuries are slight and do not prevent the players from training or competition. Injury prevention strategies should include the development of fistball‐specific protective equipment with focus on the knee and elbow joint.     

Substantial injuries influence ranking position in young elite athletes of athletics,cross‐country skiing and orienteering

The relationship between injury and performance in young athletes is scarcely studied. The aim of this study was therefore to explore the association between injury prevalence and ranking position among adolescent elite athletes. One hundred and sixty‐two male and female adolescent elite athletes (age range 15‐19), competing in athletics (n = 59), cross‐country skiing (n = 66), and orienteering (n = 37), were monitored weekly over 22‐47 weeks using a web‐based injury questionnaire. Ranking lists were collected. A significant (P  = .003) difference was found in the seasonal substantial injury prevalence across the ranked athletes over the season, where the top‐ranked (median 3.6%, 25‐75th percentiles 0%‐14.3%) and middle‐ranked athletes (median 2.3%, 25‐75th percentiles 0%‐10.0%) had a lower substantial injury prevalence compared to the low‐ranked athletes (median 11.3%, 25‐75th percentiles 2.5%‐27.1%), during both preseason (P  = .002) and competitive season (P  = .031). Athletes who improved their ranking position (51%, n = 51) reported a lower substantial injury prevalence (median 0%, 25‐75th percentiles 0%‐10.0%) compared to those who decreased (49%, n = 49) their ranking position (md 6.7%, 25‐75th percentiles 0%‐22.5%). In the top‐ranked group, no athlete reported substantial injury more than 40% of all data collection time points compared to 9.6% (n = 5) in the middle‐ranked, and 17.3% (n = 9) in the low‐ranked group. Our results provide supporting evidence that substantial injuries, such as acute and overuse injuries leading to moderate or severe reductions in training or sports performance, influence ranking position in adolescent elite athletes. The findings are crucial to stakeholders involved in adolescent elite sports and support the value of designing effective preventive interventions for substantial injuries.
