Prevalence and risk factors of dance injury during COVID-19: a cross-sectional study from university students in ChinaObjectives: Although COVID-19 has transformed dancers’ training environment worldwide, little is known on how this has affected injury prevalence, causes and risk factors. Methods: An online investigation was conducted (September to November 2020) involving Chinese full-time dance students, which covered two 6-month periods just before and during the first COVID-19 lockdown. Results: 2086 students (19 ±2.4yrs) responded. Injury prevalence before lockdown dropped from 39.6% to 16.5% during lockdown (p<0.01). A significant increase in injury severity during lockdown was noted with a 4.1% increase in moderate to severe injuries (p<0.05). During the lockdown, injuries of the lower back, feet and shoulders decreased significantly (p<0.01), but the knees, ankles and groin/hip-joint injuries remained the same. Recurrence of old injury and fatigue remained as the top 2 perceived causes of injury between the two periods with unsuitable floor (p<0.01), cold environment (p<0.05) and set/props (p<0.05) increasing. Students’ fatigue degree decreased (p<0.01) and sleep hours increased (p<0.01) during lockdown. Binary logistic regression analysis indicated that dance injury was associated with fatigue, hours of sleep, and action taken if they suspected an injury during lockdown (p<0.05), but was only related to time set aside for cool-down and age before lockdown (p<0.05). Conclusion: Although the injury prevalence dropped significantly during the first COVID-19 lockdown in Chinese dance students, the main dance injury characteristics remained the same. Decreased fatigue and longer sleep hours could explain the aforementioned drop in injury prevalence during the lockdown.
The relationship between range of motion and injuries in adolescent dancers and sportspersons: A systematic reviewBackground: The frequent and intensive training and performance of pre-professional ballet dancers and sportspersons is offered at a time when young ballet dancers and young athletes may be vulnerable to injury due to the progress through adolescence and growth spurts. Hypothesis: There are changes in range of motion during the progress through adolescence and growth periods in dancers and sportspersons. These changes in ROM can be linked to the increase of injury. Objectives: The primary aim of this systematic review is to determine whether there are changes in ROM during the progress through adolescence and growth spurts in dancers and sportspersons. The secondary aim is to determine whether these changes can predict the risk of injuries for adolescent dancers and sportspersons. Search strategy: Pubmed, Cochrane Register of Controlled Trails (CENTRAL), Cochrane Database of Systematic Reviews (CDSR), EBSCO Host databases: CINAHL Plus, MEDLINE, SPORTDiscus, Embase were searched using MeSH terms. Manual search in the Journal of Dance Medicine and Science and screening of the reference lists of identified studies and reviews was conducted. Selection criteria: Studies included adolescent dancers and sportspersons, aged 8–18, both sexes, growth spurt related to changes in ROM and injury incidence. Data collection and analysis: Search strategy was performed in the flow diagram of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two reviewers independently appraised each included study using Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) for methodological quality of the included studies. For data extraction, the following information was systematically extracted: first author and year of publication, study design, participants (sample size of mean age), age, maturation (if assessed), intervention, outcome(s), and some notes of each study. For evaluation of the risk of bias and precision the Research Triangle Institute Item Bank (RTI-IB) is included. Main results: Seven observational studies met the inclusion criteria of this current review. The results of this review suggest that there are changes in ROM during the progress through adolescence and growth spurts in dancers and sportspersons. These changes may lead to an increase in injury incidence. Conclusion: There is evidence linking to changes in ROM during the progress through adolescence and growth spurts in dancers and sportspersons. These changes in ROM may be related to injury incidence.
