BACKGROUND: Despite growing participation in circus arts, little is known about associated injuries. Understanding injury patterns is critical for developing interventions to decrease injury risk and guiding rehabilitation. OBJECTIVE: The purpose of this pilot prospective cohort study was to describe injury frequency and characteristics in adolescent and adult circus artists using a surveillance method derived from dance. METHODS: Participants included 14 adolescent [mean age 14.7 yrs (1.3); 100% female] and 10 adult circus artists [mean age 30.7 yrs (3.1); 60% female]. Circus training exposure (single session of one circus discipline) and injuries were tracked for 1 year using a dance-derived injury surveillance guideline. A regression analysis was run using total session exposures, age (in years), and years of circus experience as predictor variables for injury rate. RESULTS: Twenty-one of 24 participants completed the study. Forty-seven injuries were reported (53.2% time loss; 46.8% non-time loss). Joint injuries were most common for both groups. The injury rate per 1,000 exposures was 3 (95%CI 0.6–8.7) for adolescents and 13 (95%CI 6.9–22.01) for adults. The overall regression was significant (F(3,13)=6.66, p=0.006). The only significant predictor was age (beta=0.82, p=0.003). Total session exposures and years of circus experience had betas close to 0 (–0.11 and –0.04, respectively). CONCLUSION: This pilot study comparing injuries in adolescent and adult circus artists found age but not exposure was predictive of injury risk. Use of a standardized injury surveillance guideline in circus, similar to the one used in this study, will provide greater insight into injury patterns by allowing between-study comparison.

Objective To evaluate long-term predictors of remission in patients with medication-overuse headache (MOH) by prospective cohort study. Background Knowledge regarding long-term predictors of MOH outcome is limited. Methods Two hundred and forty MOH patients recruited from 2000 to 2005 were included in a one-year follow-up study and then subsequently followed until 31 December 2013. The median follow-up was three years (interquartile range, three years). Predictive values of selected variables were assessed by the Cox proportional hazard regression model. Results At the end of follow-up, 102 (42.5%) patients were in remission. The most important predictors of remission were lower number of headache days per month before the one-year follow-up (HR-hazard ratio = 0.936, 95% confidence interval (CI) 0.884–0.990, p = 0.021) and efficient initial drug withdrawal (HR = 0.136, 95% CI 0.042–0.444, p = 0.001). Refractory MOH was observed in seven (2.9%) and MOH relapse in 131 patients (54.6%). Conclusions Outcome at the one-year follow-up is a reliable predictor of MOH long-term remission.

IntroductionHamstring muscle injuries (HMI) continue to plague professional football. Several scientific publications have encouraged a multifactorial approach; however, no multifactorial HMI risk reduction studies have been conducted in professional football. Furthermore, individualisation of HMI management programmes has only been researched in a rehabilitation setting. Therefore, this study aims to determine if a specific multifactorial and individualised programme can reduce HMI occurrence in professional football.Methods and analysisWe conducted a prospective cohort study over two seasons within the Finnish Premier League and compare the amount of HMI sustained during a control season to an intervention season. Injury data and sport exposure were collected during the two seasons (2019–2020), and a multifactorial and individualised HMI risk reduction programme will be implemented during intervention season (2020). After a hamstring screening protocol is completed, individual training will be defined for each player within several categories: lumbo-pelvic control, range of motion, posterior chain strength, sprint mechanical output and an additional non-individualised ‘training for all players’ category. Screening and respective updates to training programmes were conducted three times during the season. The outcome will be to compare if there is a significant effect of the intervention on the HMI occurrence using Cox regression analysis.Ethics and disseminationApproval for the injury and sport exposure data collection was obtained by the Saint-Etienne University Hospital Ethics Committee (request number: IORG0007394; record number IRBN322016/CHUSTE). Approval for the intervention season was obtained from the Central Finland healthcare District (request and record number: U6/2019).

ObjectiveTo describe weekly illness prevalence and illness symptoms by sex in youth floorball players during one season.DesignProspective cohort study.SettingPlayers who were registered to play community level floorball during the 2017–2018 season (26 weeks) in two provinces in southern Sweden.Participants471 youth players aged 12–17 years. Mean (SD) age for 329 male players 13.3 (1.0) years and 142 female players 13.7 (1.5) years.Primary and secondary outcome measuresWeekly self-reported illness prevalence and illness symptoms according to the 2020 International Olympic Committee’s consensus recommendations.Results61% of youth floorball players reported at least one illness week during the season, with an average weekly illness prevalence of 12% (95% CI 10.8% to 12.3%). The prevalence was slightly higher among females (13%, 95% CI 11.6% to 14.3%) than males (11%, 95% CI 9.9% to 11.7%), prevalence rate ratio 1.20 (95% CI 1.05 to 1.37, p=0.009). In total, 49% (53% male, 43% female) of illness reports indicated that the player could not participate in floorball (time loss), with a mean (SD) absence of 2.0 (1.7) days per illness week. Fever (30%), sore throat (16%) and cough (14%) were the most common symptoms. Female players more often reported difficulty in breathing/tight airways and fainting, and male players more often reported coughing, feeling tired/feverish and headache. Illness prevalence was highest in the peak winter months (late January/February) reaching 15%–18% during this period.ConclusionsOur novel findings of the illness prevalence and symptoms in youth floorball may help direct prevention strategies. Athletes, coaches, parents and support personnel need to be educated about risk mitigation strategies.Trial registration numberNCT03309904.

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.
