The relationship between flourishing, injury status, and resilience in collegiate athletes

Background Flourishing is a multi-dimensional construct that encompasses physical, psychological and social well-being. A proposed positive attribute of flourishing is resilience, which is the ability to bounce back despite the presence of stressors. A common stressor among athletes is overuse injuries, which may negatively affect well-being. Objective To examine the relationships of resilience and overuse injury with flourishing in collegiate athletes. Materials and methods 253 college athletes participated. The Flourishing Scale, Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC), and Brief Resilience Scale (BRS) were administered via online questionnaire. For OSTRC scores, athletes were classified into injury and participation status groups. For BRS scores, athletes were classified into low resilience (LR), normal resilience (NR), and high resilience (HR) groups. Results Median flourishing score was 50.0 (46.5–53.5); mean BRS score was 21.6 (SD 4.3). Overuse injury and substantial overuse injury incidence proportion (IP) were 25.4 (95% CI: 20.3, 30.5) and 9.1 (95% CI: 7.0, 11.2). The IP for participants unable to play was 15.1 (95% CI: 12.9, 17.2). Significant differences were found in flourishing among resilience groups (p = 0.002) but not among overuse injury groups (p = 0.140) or participation variables (p = 0.205). Conclusion College athletes demonstrated high flourishing scores. Flourishing demonstrated a significant relationship with resilience across all groups but not among overuse injury or participation status. This finding indicates that college athlete well-being is strongly associated with resilience. Future longitudinal studies are needed to determine if resilience can be modified to positively influence athlete well-being.

Predicting Injury Status in Adolescent Dancers Involved in Different Dance Styles: A Prospective Study.

The positive effects of dance on health indices in youth are widely recognized, but participation in dance is accompanied with a certain risk of injury. This prospective study aimed to investigate injury occurrence and to evaluate the possible influences of specific predictors on the occurrence of musculoskeletal problems and injuries in adolescent dancers. Participants were 126 dancers (21 males; 11–18 years), who were competitors in the urban dance, rock and roll, and standard/Latin dance genres. Predictors included sociodemographic factors, anthropometric/body build indices, sport (dance) factors, and dynamic balance. The outcome variable was injury status, and this was evaluated by the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC). Predictors were evaluated at baseline, and outcomes were continuously monitored during the study period of 3 months. During the study course, 53% of dancers reported the occurrence of a musculoskeletal problem/injury, and dancers suffered from an average of 0.72 injuries over the study period (95% CI: 0.28–1.41), giving a yearly injury rate of 280%. Gender and dance styles were not significantly related to the occurrence of injury. Higher risk for injury was evidenced in older and more experienced dancers. Dynamic balance, as measured by the Star Excursion Balance Test (SEBT), was a significant protective factor of injury occurrence, irrespective of age/experience in dance. Knowing the simplicity and applicability of the SEBT, continuous monitoring of dynamic balance in adolescent dancers is encouraged. In order to prevent the occurrence of musculoskeletal problems/injuries in youth dancers, we suggest the incorporation of specific interventions aimed at improving dynamic balance.

Japanese translation and validation of web-based questionnaires on overuse injuries and health problems

This study aimed to translate and culturally adapt the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O) and the Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H) into the Japanese context. The validity and reliability of these translated questionnaires examining overuse injuries and health problems among Japanese university athletes were also examined. The translation was performed following an internationally recognized methodology. A total of 145 athletes were tracked over 10 consecutive weeks and four questions were added in the 10th week to examine the questionnaires’ content validity. Test-retest analysis for reliability was performed 24–72 hours after the 10th week of registration. Internal consistency was determined by calculating Cronbach’s a during the cohort study. No major disagreements were found in the translation process. The translated questionnaires had high acceptance and compliance, with an average response rate of over 80% throughout the 10-week cohort study. Most participants reported that the questionnaires were not difficult to complete, there were no items they wanted to change or add, and that the web-based technique worked effectively. Good test-retest reliability and high internal consistency was observed in the translated questionnaires. The translated questionnaires were found to be valid, reliable, and acceptable for medically monitoring Japanese athletes.

Epidemiology of Traumatic and Overuse Injuries in Swiss Professional Male Ice Hockey Players.

Background:Ice hockey injury patterns in Europe were last evaluated in the 1990s.Purpose:The aim of this study was to assess the frequency, type, location, and incidence of traumatic injuries, as well as the prevalence and relative effect of overuse injuries in professional male ice hockey players.Study Design:Descriptive epidemiology study.Methods:Traumatic injuries were assessed using a standardized injury report form over a 1-year period (including the preparatory phase and season). The Oslo Sports Trauma Research Centre Overuse Injury Questionnaire was used to determine overall and substantial overuse injuries and their relative effect on ice hockey players.Results:Five Swiss National League teams participated in the study. From a total of 321 recorded injuries, 179 led to time loss from sport. The game-related time-loss injury incidence during the season was 88.6/1000 player-game hours.Time-loss injuries affected mainly the hip/groin/thigh region (23%), followed by the head (17%). Most time-loss injuries were classified as muscle strains (24%), followed by concussions (18%). The most common injury mechanism involved collision with an opponent’s body (31%), and right forward players (23%) were most likely to report a game-related injury. Most injuries (27%) occurred within the defending zone along the boards. The average prevalence rates of all overuse and substantial overuse injuries were 49% and 13%, respectively. The hip/groin displayed the highest average prevalence for all overuse problems (16%), translating to the highest relative effect.Conclusion:Muscle strains and concussions were the most frequent time-loss injuries in Swiss professional ice hockey players. The hip/groin was the most affected region for both traumatic and overuse injuries.

Injuries And Injury-related Pain Relationships To NSAID Use And Abuse In Collegiate Athletes

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used by athletes to treat musculoskeletal pain and injuries. The relationship between NSAID use and current pain and injuries in collegiate athletes in unknown. Understanding this relationship is important due to the potential for athletes to improperly obtain and abuse NSAIDs. PURPOSE: To investigate how pain and injury effects current collegiate athlete NSAID use during both in and out of season. METHODS: Athletes from all 3 NCAA Divisions self-reported data on in and out of season NSAID use, purchase, and dosage. The Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC) was used to evaluate current level of participation and pain. Logistic regressions were used to assess the relationship between current NSAID use and OSTRC total score. Models were adjusted for age, gender, NCAA division, history of orthopaedic surgery, and history of major injury, with unadjusted and adjusted Odds Ratios (OR) with 95% confidence intervals (95% CI). χ2 and Kruskall Wallis tests assessed the relationship between NSAID use and OSTRC overuse and substantial overuse injuries in and out of season. RESULTS: 252 athletes (age of 19.43 ± 1.2 years; Male: 28%; D1: 101, D2: 74, D3: 77) completed the survey. 33% currently used NSAIDs, 48% self-purchased, and 53% took two pills per dose. 36% did not answer where NSAIDs were obtained and 34% did not answer what dosage was taken. The OSTRC median score was 0 (IQR: 0-22). 53% had overuse injuries, while 20% had substantial overuse injuries. Current NSAID users had greater odds of having increased OSTRC scores (1.03 (95% CI: 1.02, 1.04), p<0.001). OSTRC overuse and substantial overuse injured athletes were more likely to use NSAIDs (over use: χ2 = 34.0, p<0.001; substantial overuse: χ2 = 28.2, p<0.001) and use them out of season (over use: χ2 =24.4, p<0.001; substantial overuse: χ2 = 21.4, p<0.001) as compared to non-overuse and non-substantial overuse injured athletes. CONCLUSION: NSAID use is high and the majority of athletes purchase their own NSAIDs, instead of receiving them from a medical professional. Injured athletes are more likely to use NSAIDs both in and out of season. Sports medicine professionals needs to monitor NSAID use and abuse in order to mitigate potential NSAID-related negative health impacts.

The Effect Of Injuries And Pain On Athletic Identity Across NCAA Divisions

There is a high prevalence of pain and injury in collegiate athletes, which can affect playing time and performance. Previous studies have observed that surgery and concussions can affect athletic identity. Currently, there is a paucity of research investigating how current pain and injury affect athletic identity. PURPOSE: To determine how current collegiate athlete pain and injury affect athletic identity and how these relationships differ across NCAA divisions. METHODS: NCAA division 1 (D1), 2 (D2), and 3 (D3) athletes were administered a questionnaire through an encrypted database. The Athletic Identity Questionnaire (AIM) and Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC) were used within the survey. AIM estimates self-perceived athletic identity while OSTRC measures level of participation, training volume, performance, and pain. Athletes were further classified by OSTRC scores into overuse and substantial overuse injuries. Multivariable and logistic regressions assessed the relationship between Aim, OSTRC scores, and overuse injury. Models were adjusted for age, gender, NCAA division, history of orthopedic surgery, and history of major injury, with unadjusted and adjusted coefficients and Odds Ratios (OR) with 95% confidence intervals (95% CI). RESULTS: 252 athletes (age of 19.4 years (1.2); female: 181, male: 70; D1: 101, D2: 74, D3: 77) participated. Mean AIM scores were D1: 37.98 (7.61), D2: 37.03 (37.03), and D3: 38.86 (6.98). The OSTRC median score was 0 (IQR: 0-22). 127 (50%) athletes had an overuse injury while 47 (19%) had a substantial overuse injury. Adjusted total OSTRC score was -0.67 (95% CI: -2.4, 1.1; p=0.474). Adjusted OR for OSTRC overuse injury was 1.00 (95% CI: 0.97, 1.04; p=0.589) and substantial overuse injury was 0.95 (95% CI: 0.91, 0.99; p=0.036). Similar results were observed between gender and division subgroups. CONCLUSION: After adjusting for confounding variables, it was determined that substantial overuse injuries negatively affected athletic identity, regardless of gender or NCAA division. Sports medicine professionals need to consider the possibility of lost athletic identity when an athlete sustains an injury. Measures should be taken to ensure that athletes continue to have meaningful contribution to sport following pain or injury.

The Relationship Between Flourishing, Pain, And Injury In Collegiate Athletes

Flourishing encompasses a holistic representation of physical, psychological, and social health. However, pain and injury can negatively affect health. Currently, there is little research on flourishing within collegiate athletes. PURPOSE: To evaluate the relationship of pain and injury with flourishing in NCAA athletes and to compare by division. METHODS: NCAA division 1 (D1), 2 (D2), and 3 (D3) athletes were given a questionnaire incorporating the flourishing scale and the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC). Athletes were further classified by OSTRC scores into overuse and substantial overuse injuries. Multivariable regressions with logarithmic transformations and ANCOVAs were performed to investigate the relationship between flourishing and OSTRC pain and flourishing, overuse and substantial overuse injury. Confounders controlled for included age, gender, history of orthopaedic surgery and major injury, hours of sleep, and non-steroidal anti-inflammatory use. Unadjusted and adjusted effect size and 95% confidence intervals (95% CI) were reported. RESULTS: 253 athletes (Age: 19.43 (1.18) years; Male: 70; D1: 102, D2: 74, D3: 77; 7-8 hours of sleep: 157) participated. Mean flourishing scores were D1: 48.59 (10.43), D2: 50.08 (5.31), and D3: 48.58 (8.09). The median OSTRC score was 0 (0-22). 124 reported an overuse injury and 47 a substantial overuse injury. There was a unadjusted negative relationship between OSTRC total score and flourishing (-5.2% (95% CI: -10%, 1%), p=0.037); however there was no relationship after controlling for confounders (0.1% (95% CI: -2.6%, 2.7%), p=0.989). There was no relationship between overuse injury and flourishing (-0.23 (95% CI: -2.57, 2.11), p= 0.848). There was an unadjusted negative relationship between substantial overuse injuries and flourishing (-2.77 (95% CI: -5.43, -0.12), p=0.042), but there was no relationship after controlling for confounders (1.97 (95% CI: -4.95, 1.01), p=0.196). These relationships were similar by division. CONCLUSION: College athletes have high flourishing, and have similar flourishing between all NCAA divisions. Pain and injury have a negative relationship to flourishing; however, these relationships are confounded by surgical and injury history, and lifestyle.

Improved reporting of overuse injuries and health problems in sport: an update of the Oslo Sport Trauma Research Center questionnaires

In 2013, the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O) was developed to record the magnitude, symptoms and consequences of overuse injuries in sport. Shortly afterwards, a modified...

Elite Ice Hockey Goalkeepers Have a High Prevalence of Hip and Groin Problems Associated With Decreased Sporting Function: A Single-Season Prospective Cohort Study.

Background:The modern style of goalkeeping in ice hockey is thought to predispose athletes to hip and groin problems. However, little is known about the magnitude of these problems in elite goalkeepers.Purpose:To describe the incidence, prevalence, and severity of hip and groin problems in elite ice hockey goalkeepers over the course of a single season.Study Design:Descriptive epidemiology study.Methods:We invited all elite Swedish ice hockey goalkeepers (n = 128) to participate in this prospective cohort study. Every second week, players reported hip and groin problems experienced within the past 14 days on the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC-O), classifying problems into “all” and “substantial” hip and groin problems. Three times during the season (pre-, mid-, and end-season), players reported hip and groin function on the Hip and Groin Outcome Score (HAGOS) as well as on the OSTRC-O.Results:A total of 101 goalkeepers participated in the study (83.3% male [seniors, 44.1%; juniors, 39.2%], 16.7% female). The cumulative incidences of all hip and groin problems and substantial hip and groin problems were 69% (95% CI, 59%-79%) and 36% (95% CI, 26%-46%), respectively. The average biweekly prevalence for all hip and groin problems and substantial hip and groin problems was 28.1% (95% CI, 25.0%-31.3%) and 10% (95% CI, 8.7%-11.4%), respectively. Among all the reported hip and groin problems, 16.9% (n = 70) were acute, 83.1% (n = 343) were because of overuse, and 15.5% (n = 64) led to time loss. HAGOS did not differ in the pre-, mid-, or end-season. Players reporting hip and groin problems on the OSTRC-O had significantly worse HAGOS scores than players without problems (P < .01).Conclusion:Hip and groin problems are highly prevalent in elite ice hockey goalkeepers. During a competitive season, 69% of players experienced hip and groin problems and 36% of players suffered from substantial problems. The vast majority of problems were because of overuse, not leading to time loss but related to reduced self-reported hip and groin function.

Investigating the Prevalence and Predictors of Injury Occurrence in Competitive Hip Hop Dancers: Prospective Analysis.

Hip hop is a popular form of competitive and recreational sport worldwide, but studies rarely investigate injury prevalence and factors associated with injury occurrence in this sport. This study aimed to prospectively examine injury occurrence in hip hop dancers in a three-month period and to evaluate potential predictors of injury occurrence in hip hop dancers. The participants were 129 competitive hip hop dancers (114 females, 17.95 ± 4.15 years of age). Study predictors were obtained at study baseline and included sociodemographic factors, sport-related factors, previous injury status, anthropometric and body build indices (body height, mass, body mass index, and body composition variables), and dynamic balance performance (obtained by the Star Excursion Balance Test—SEBT). The outcome was injury occurrence, which was prospectively observed once a week by the Oslo Sports Trauma Research Center Overuse Injury Questionnaire (OSTRC). During the course of the study, 101 injuries occurred, equating to an annual injury incidence of 312%. On average, each dancer suffered 0.78 injuries (95% Confidence Interval (95% CI): 0.61–0.97) across a study period of three months (0.76 (95% CI: 0.60–0.95) and 0.93 (95% CI: 0.75–1.13), in females and males, respectively; Mann Whitney Z-value: 0.68, p = 0.52). Seventeen percent of dancers suffered multiple injuries, and 49% of all injuries were time-loss injuries. The knee was the most frequently injured body location (42% of all reported injuries), followed by the back region (32%) and the ankle (15%). Previous injury was a strong predictor of injury occurrence (Odds Ratio: 3.76, 95% CI: 1.87–4.59). Lower injury risk was evidenced among those participants who achieved better scores on several SEBT variables, irrespective of gender and previous injury status; with no significant influence of anthropometric and body build variables on injury occurrence. This study highlighted a high injury rate in hip hop dancers. Dancers and coaches should be informed about the certain protective effects of dynamic balance on the prevention of musculoskeletal injury in hip hop in order to assure safe and effective practices. The usage of SEBT as a convenient and cheap testing procedure is encouraged in other dance disciplines.

The recovery after Achilles tendon rupture: a protocol for a multicenter prospective cohort study

BackgroundAchilles tendon rupture (ATR) is a common sports injury, with a rising incidence and significant impairments. Due to the lack of treatment guidelines, there is no consensus about diagnostic methods, primary treatment (non-surgical or surgical) and rehabilitation. It is hypothesized that this lack of consensus and guidelines leads to sub-optimal recovery and higher societal costs.The primary aim of this study is to give a broad insight into the recovery after ATR. Secondarily this study aims to explore factors contributing to recovery and gain insight into the cost-effectiveness of ATR management.MethodsThis multicenter prospective cohort study will include all adult (≥ 18 years) patients with an ATR treated at the three main hospitals in the Northern Netherlands: University Medical Center Groningen, Martini Hospital Groningen and Medical Center Leeuwarden. All subjects will be invited for three visits at 3, 6 and 12 months post-injury. The following data will be collected: patient-reported outcome measures (PROMs), physical tests, imaging and economic questionnaires. At 3 months post-injury personal, injury, and treatment data will be collected through a baseline questionnaire and assessment of the medical file. The PROMs concern the Dutch version of the Achilles Tendon Total Rupture Score, EQ-5D-5 L, Oslo Sport Trauma Research Center Overuse Injury Questionnaire, Injury Psychological Readiness Return to Sport Scale, Tampa Scale of Kinesiophobia, Expectations, Motivation and Satisfaction questionnaire and a ranking of reasons for not returning to sport. The administered physical tests are the heel-rise test, standing dorsiflexion range of motion, resting tendon length and single leg hop for distance. Ultrasound Tissue Characterization will be used for imaging. Finally, economic data will be collected using the Productivity Cost Questionnaire and Medical Consumption Questionnaire.DiscussionThis prospective cohort study will contribute to optimal decision making in the primary treatment and rehabilitation of ATRs by providing insight into (1) ATR recovery (2) novel imaging for monitoring recovery (3) (barriers to) return to sport and (4) cost-effectiveness of management. The analysis of these data strives to give a broad insight into the recovery after ATR as well as provide data on novel imaging and costs, contributing to individualized ATR management.Trial registrationTrialregister.nl.

The SMS, Phone, and medical Examination sports injury surveillance system is a feasible and valid approach to measuring handball exposure, injury occurrence, and consequences in elite youth sport.

Current methods of sports injury surveillance are limited by lack of medical validation of self-reported injuries and/or incomplete information about injury consequences beyond time loss from sport. The aims of this study were to (a) evaluate the feasibility of the SMS, Phone, and medical Examination injury surveillance (SPEx) system (b) to evaluate the proportion of injuries and injury consequences reported by SPEx when compared to outcomes from a modified version of the Oslo Sports Trauma Research Centre (OSTRC) Overuse Injury Questionnaire. We followed 679 elite adolescent handball players over 31weeks using the SPEx system. During the last 7weeks, we also implemented a modified OSTRC questionnaire in a subgroup of 271 players via telephone interviews. The weekly response proportions to the primary SPEx questions ranged from 85% to 96% (mean 92%). SMS responses were received from 79% of the participants within 1day. 95% of reported injuries were classified through the telephone interview within a week, and 67% were diagnosed by medical personnel. Comparisons between reported injuries from SPEx and OSTRC demonstrated fair (κ=39.5% [25.1%-54.0%]) to substantial prevalence-adjusted bias-adjusted kappa (PABAK=66.8% [95% CI 58.0%-75.6%]) agreement. The average injury severity score difference between SPEx and the OSTRC approach was -0.2 (95% CI -3.69-3.29) of possible 100 with 95% limits of agreement from(-14.81-14.41). These results support the feasibility and validity of the SPEx injury surveillance system in elite youth sport. Future studies should evaluate the external validity of SPEx system in different cohorts of athletes.

Application of a Simple Surveillance Method for Detecting the Prevalence and Impact of Overuse Injuries in Professional Men's Basketball.

The aim of this study was to use the Oslo Sports Trauma Research Center (OSTRC) Overuse Injury Questionnaire to record overuse injuries over a single season for a men's professional basketball team to (a) assess the prevalence and severity of overuse injuries and (b) determine the efficacy of this method in identifying overuse injuries in comparison with the team physiotherapist's detection of these injuries. Thirteen athletes from a men's professional basketball team participated in this study. The self-reported, OSTRC injury questionnaire was used to record overuse conditions of the ankle, knee, and lower back over an entire 24-week season. Standard time-loss injury registration methods were also used to record overuse conditions by the physiotherapist. Overuse injury rates per 1,000 hours of athlete exposure and average weekly prevalence of overuse injuries were calculated using the results of the questionnaire. A total of 183 overuse conditions were identified by the questionnaire, whereas only 28 overuse conditions were identified by the physiotherapist. The team's average weekly prevalence of all overuse conditions was 63% (95% confidence interval [CI]: 60-66), with the highest prevalence of injury affecting the lower back (25.9% [95% CI: 19.7-32.1]). The overuse injury rate per 1,000 hours of athlete exposure was 6.4. The OSTRC overuse injury questionnaire captures many more overuse injuries in basketball than standard time-loss methods. The prevalence of lower back injuries is higher than that previously reported in basketball. This additional method of overuse injury surveillance may more accurately quantify the overuse injury problem in basketball and aid earlier intervention and management of these conditions.

The impact of patellar tendinopathy on sports and work performance in active athletes

ABSTRACTGreater insight into sports and work performance of athletes with patellar tendinopathy (PT) will help establish the severity of this common overuse injury. Primary aim of this study is to investigate the impact of PT on sports and work performance. Seventy seven active athletes with PT (50 males; age 28.1 ± 8.2 years; Victorian Institute of Sports Assessment Patella 56.4 ± 12.3) participated in this survey. Sports performance, work ability and work productivity were assessed using the Oslo Sports Trauma Research Center overuse injury questionnaire, the single-item Work Ability Index and the Quantity and Quality questionnaire, respectively. Reduced sports performance was reported by 55% of the participants; 16% reported reduced work ability and 36% decreased work productivity, with 23% and 58%, respectively, for physically demanding work. This study shows that the impact of PT on sports and work performance is substantial and stresses the importance of developing preventive measures.

Groin Problems in Male Soccer Players Are More Common Than Previously Reported

Background: The majority of surveillance studies in soccer have used a time-loss injury definition, and many groin problems result from overuse, leading to gradually increasing pain and/or reduced performance without necessarily causing an absence from soccer training or match play. Thus, the magnitude of groin problems in soccer has probably been underestimated in previous studies based on traditional injury surveillance methods. Purpose: To investigate the prevalence of groin problems among soccer players of both sexes and among male soccer players at different levels of play through a new surveillance method developed to capture acute and overuse problems. Study Design: Descriptive epidemiology study. Methods: We registered groin problems during a 6-week period of match congestion using the Oslo Sports Trauma Research Center Overuse Injury Questionnaire. A total of 240 players from 15 teams across different levels of play and from both sexes were included, and they responded to the weekly questionnaire. We calculated the average weekly prevalence of all groin problems and substantial groin problems. Results: Of the 240 players, 112 male players (59%) and 20 female players (45%) reported at least 1 episode of groin problems. The average weekly prevalence of any groin problem and substantial groin problem for all male players was 29% (range, 23%-32% across different levels) and 10% (7%-13%), respectively. Elite male players had an increased risk of experiencing groin problems (odds ratio: 3.1, 95% CI: 1.5-6.4, P = .03) compared with elite female players. There was no difference in the risk of experiencing groin problems among elite, subelite, and amateur male players. For substantial problems, there was no difference between elite male and elite female players or among levels of play for senior male soccer players. Conclusion: We found a high prevalence of groin problems among male soccer players during a period with match congestion. Time-loss definition as used in previous injury surveillance studies captured only one-third of the male groin problems registered with the new method. Elite male players had 3 times’ higher risk of reporting groin problems as compared with elite female players, while playing level did not influence the risk of reporting a groin problem among males.

Danish translation and validation of the Oslo Sports Trauma Research Centre questionnaires on overuse injuries and health problems.

The Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC-O) and the Oslo Sports Trauma Research Centre questionnaire on Health Problems (The OSTRC-H) make it possible to monitor illness and injury at regular intervals capturing prevalence and incidence of acute injury, overuse injury, and illnesses. The aim of this study was to translate, culturally adapt, and establish the face validity of the OSTRC-O and the OSTRC-H into a Danish context (DK) through cognitive interviews and the assessment of test-retest reliability. The OSTRC-O.DK was distributed to 57 heterogenous respondents; response rate was 89%. The OSTRC-H was distributed to 58 heterogenous respondents; response rate was 86%. No major disagreements were observed between the original and translated versions of the questionnaires. The OSTRC-O had high internal consistency (Cronbach's alpha 0.80-0.93). The primary reliability analyses including all participants, showed reliability ICC: 0.62 (95% CI: 0.42-0.77. The secondary reliability analyses that only included subjects who did not change injury region from the test to the retest showed an ICC of 0.86 (95% CI: 0.77-0.92).The questionnaires were found to be valid, reliable, and acceptable for use in a Danish population.

Evaluation of an interprofessional student placement: qualitative findings and implications

self-identified as drag flickers and 292 as non-drag flickers. The sample comprised of 242 males and 188 females with a mean age of 25.7 years (SD8.3), height of 1.74metres (SD9.3), mass of 71.7 kilograms (SD13.0) and 15.8 years (SD8.0) years of experience. All participants were currently competing at local, national, or international level. Recruitment occurred over a 3 month period during the regular season. Participants completed an online questionnaire to determine the prevalence and severity of lower limb and lumbar injuries using a modified Oslo Sports Trauma Research Centre (OSTRC) Overuse Injury Questionnaire. The questionnaire reports the 3-months prevalence injury rate and severity of injury for the ankle, knee, hip and lumbar. Univariate logistics regression was used to determine whether drag flickers had a higher prevalence of ankle, knee, hip and lumbar injuries than non-drag flickers. MannWhitney U tests compared the difference in severity score of the injuries between drag flickers and non-drag flickers. Results: The results showed that drag flickers had significantly higher prevalence of hip (OR 1.541, 95% CI 1.034, 2.365, p= 0.043) and lumbar injuries (OR 1.564, 95% CI, 1.034, 2.365 and p= 0.034) compared to non-drag flickers. No significant differences were observed between drag flickers and non-drag flickers in ankle (OR: 1.041, 95% CI, 0.631, 1.462, p= 0.851) and knee injuries (OR: 1.135; 95% CI, 0.750, 1.719, p= 0.548). There were no significant differences in severity in ankle, knee, hip and lumbar injury between the two groups. Conclusion(s): There is a significantly higher prevalence of injury in drag flickers compared to non-drag flickers in the hip and lumbar spine, but no significant difference in the severity of these injuries. Implications: This study has identified that a higher prevalence of hip and lumbar injuries among drag flickers compared to non-drag flickers. This data can lead to future biomechanical or skills studies investigating the potential mechanisms of injuries in this specific group of athletes with a view to developing strategies to mitigate the occurrence of hip and lumbar injuries injury among drag flickers.
