Seasonal variation in musculoskeletal extremity injuries in school children aged 6-12 followed prospectively over 2.5 years: a cohort study.

ABSTRACT: The type and level of physical activity in children vary over seasons and might thus influence the injury patterns. However, very little information is available on the distribution of injuries over the calendar year. This study aims to describe and analyse the seasonal variation in extremity injuries in children.Prospective cohort study.10 public schools in the municipality of Svendborg, Denmark.A total of 1259 school children aged 6-12 years participating in the Childhood Health, Activity, and Motor Performance School Study Denmark.School children were surveyed each week during 2.5 school-years. Musculoskeletal injuries were reported by parents answering automated mobile phone text questions (SMS-Track) on a weekly basis and diagnosed by clinicians. Data were analysed for prevalence and incidence rates over time with adjustments for gender and age.Injuries in the lower extremities were reported most frequently (n=1049). There was a significant seasonal variation in incidence and prevalence for lower extremity injuries and for lower and upper extremity injuries combined (n=1229). For the upper extremities (n=180), seasonal variation had a significant effect on the risk of prevalence. Analysis showed a 46% increase in injury incidence and a 32% increase in injury prevalence during summer relative to winter for lower and upper extremity injuries combined.There are clear seasonal differences in the occurrence of musculoskeletal extremity injuries among children with almost twice as high injury incidence and prevalence estimates during autumn, summer and spring compared with winter. This suggests further research into the underlying causes for seasonal variation and calls for preventive strategies to be implemented in order to actively prepare and supervise children before and during high-risk periods.

Project description:ObjectiveThe purpose of this study was to examine associations between level of kinesiophobia and improvement in physical function during recovery from lower extremity injury.MethodsA total 430 adults (mean [SD]: age = 27.3 [6.4] years; sex = 70.5% men; body mass index = 27.6 [5.2] kg/m2) were included in the analyses. Using the Patient-Reported Outcomes Measurement Information System, physical function was evaluated in parallel with treatment from a physical therapist at the initial visit and every 3 weeks until final visit or up to 6 months. A Tampa Scale of Kinesiophobia (TSK-17) score of >41 indicated elevated TSK. Four TSK groups were identified: (1) TSK score improved from >41 at initial visit to <41 by final visit (TSK_I), (2) TSK score was <41 at initial and final visits (TSK-), (3) TSK score was >41 at initial and final visits (TSK+), and (4) TSK score worsened from <41 at initial visit to ≥41 by final visit (TSK_W). Linear mixed effects models were used to examine differences between groups in improved physical function over time, with adjustment for depression and self-efficacy.ResultsGroups with elevated kinesiophobia at the final visit had smaller positive improvements in physical function (mean change [95% CI]: TSK+ = 7.1 [4.8-9.4]; TSK_W: 6.0 [2.6-9.4]) compared with groups without elevated kinesiophobia at the final visit (TSK_I = 9.8 [6.4-13.3]; TSK- = 9.7 [8.1-11.3]) by 12 weeks.ConclusionsElevated kinesiophobia that persists or develops over the course of care is associated with less improvement in physical function within military and civilian cohorts.ImpactThe findings of this prospective longitudinal study support the need to assess for elevated kinesiophobia throughout the course of care because of its association with decreased improvement in physical function.Lay summaryTo help improve your physical function, your physical therapist can monitor the interaction between fear of movement and your clinical outcomes over the course of treatment.

Project description:BackgroundWhile participation in sports-related activities results in improved health outcomes, high school athletes are at risk for lower extremity injuries, especially ankle, knee, and thigh injuries. Efforts to promote the adoption and implementation of evidence-driven approaches to reduce injury risk among school-aged athletes are needed. However, there is limited research regarding the perceived barriers, facilitators, and adherence factors that may influence the successful implementation of effective warm-up routines among this population.MethodsWe conducted a qualitative study using semi-structured interviews and focus groups to assess high school basketball coach and player current practices, knowledge, and perspectives about warm-ups and lower-extremity injuries (LEIs). We interviewed coaches (n = 12) and players (n = 30) from May to October 2019. Participants were recruited from public high schools in a joint school district in Southern California. Multiple coders employed thematic analysis of the data using validated methods.ResultsCoaches and players reported regular engagement (e.g., daily) in warm-up routines, but the time dedicated (range 5-45 min), types of exercises, and order varied substantially. Players often co-lead the warm-up practice with the coach or assistant coach. Despite regular engagement in warm-up, players and coaches report multiple challenges, including (1) limited time and space to warm-up effectively at games, (2) a perception that young players are not prone to injury, (3) competing demands for coaches' time during practice, and (4) coaches' lack of knowledge. Coaches and players perceive that warming up before practice will result in fewer injuries, and many players are motivated to warm up as a result of their personal injury experience; however, they desire guidance on the ideal exercises for preventing injury and training on the proper form for each exercise.ConclusionsRegular involvement in basketball warm-up routines is common among high school teams, but the methods and time dedicated to these practices varied. Players and coaches are eager for more information on warm-up programs shown to reduce LEIs.
