The annual frequency of injury among dancers has been reported to range between 23-84% while as many as 95% of professional dancers have ongoing pain. The discrepancy between the number of reported injuries and the amount of pain reported at any given time could be related to the definition of injury, or how dancers' themselves perceive injury with respect to pain and activity limitation thresholds. For many reasons, dancers may be dancing through or past what health care providers may conceive as injury. This can put them at risk of future recurrent or chronic injury. The purpose of this study is to gain insight into professional dancers' perception of musculoskeletal (MSK) injury in order to understand at which point pain limits a dancer's ability to continue to perform and to determine what factors influence a dancer's perception of injury and decision to seek or not seek care. We will investigate whether this is influenced by available medical services, a supportive dance environment, or other factors. In addition, the issue of non-reporting of injuries will be studied. This is very important because it affects all measures of injury frequency and risk for dancers.
