Design: Cross-sectional survey. Study Population: All dancers employed by: The National Ballet of Canada, Toronto Dance Theatre, Batsheva Dance Company and Ensemble (Israel), The Kibbutz Contemporary Dance Company (Israel), the Royal Swedish Ballet (Sweden), and the Royal Danish Ballet (Denmark). Total approximate number of participants is 294. Methods: Two questionnaires will be distributed to participants. The Self-Estimated Functional Inability because of Pain (SEFIP) questionnaire is a validated tool for dancers which has shown good agreement with actual pain found on physical examination. The SEFIP will be used in order to measure pain and functional deficits. An additional questionnaire will be used to gain further information regarding the above research questions. There will be an area for the dancers to include any additional comments in relation to these subjects in order to capture further qualitative data. Data Analysis: Descriptive statistics will be reported in the form of percentages and means with standard deviations. Non-parametric tests will be used to analyze categorical variables. 95% confidence intervals will be reported for each analysis. The qualitative data captured in the open-ended questions will be analyzed for common themes in order to provide further explanation for the quantitative data as well as to provide additional information for further research.
