Brief Summary

Study Design: Evaluation of the psychometric properties of a translated, culturally adapted questionnaire. Objective: Translating, culturally adapting, and validating the Italian version of the Dance Functional Outcome Survey (DFOS-IT), allowing its use with Italian-speaking dancers to evaluate their musculoskeletal health and wellbeing inside and outside Italy. Summary of Background Data: Musculoskeletal injuries are a phenomenon of huge prevalence and has been a major focus within peer-reviewed literature since the 1980s. Growing attention is devoted to standardized outcome measures to improve interventions for injured dancers. A translated form of the DFOS, the only existing outcome measure that focus on the unique functional requirements of dancers, has never been validated within the Italian dancers population.

Outcome Measures

Primary Outcomes (2)

• Dance Functional Outcome Score

  Self-reported functional outcome questionnaire for ballet and modern dance populations, applicable to musculoskeletal injuries of the low back and lower extremities. The 14-question DFOS assesses the dancer's ability in areas of activities of daily living (ADL, 40 points) and dance technique (technique, 50 points). Total score from 0 to 90, subscore Activities of daily living 40, Technique 50. Higher scores represent better outcomes. Total points are normalized to a percentage, with 100% representing full function without limitations.
