title: Reliability, validity, and responsiveness of a Canadian French adaptation of the Western Ontario Rotator Cuff (WORC) index.
abstract: METHODS
  Clinical measurement.
  
  
  OBJECTIVE
  Several questionnaires assess symptoms and functional limitations following shoulder disorders, but few are available in French. The purposes were to translate and culturally adapt the Western Ontario Rotator Cuff (WORC) index into Canadian French and to evaluate its validity, reliability and responsiveness.
  
  
  METHODS
  In accordance with standard procedure, the WORC original version was translated and cross-culturally adapted into Canadian French (WORC-CF). Then, 87 patients with rotator cuff (RC) disorders completed the WORC-CF on three occasions: baseline, two days later to evaluate reliability, and four weeks later to evaluate responsiveness.
  
  
  RESULTS
  Cross-cultural adaptation was performed without problems with content or language. WORC-CF was found to be reliable (Intraclass Correlation Coefficient = 0.96), valid (high correlation with Disability of the Arm, Shoulder and Hand [DASH]) and responsive (Standardized Response Mean = 1.54).
  
  
  CONCLUSIONS
  WORC-CF can now be used to assess functional impairment in patients with RC disorders.
