TI  - Responsiveness of the Brazilian-Portuguese version of the Oswestry Disability 
      Index in subjects with low back pain.

AB  - When quality of life questionnaires are used as measures of treatment outcomes, 
      it is essential to know how well these can respond to clinical changes. The 
      objective of this study is to examine the responsiveness of the 
      Brazilian-Portuguese version of the Oswestry Disability Index (ODI-Brazil) in 
      subjects with chronic low back pain submitted to a physical therapy program. 
      Thirty subjects with chronic low back pain completed the ODI-Brazil 
      questionnaire, along with an 11-point pain visual analogue scale (Pain VAS), and 
      the Brazilian-Portuguese version of Roland-Morris disability questionnaire before 
      and after the program. All patients also completed a global perception of change 
      Likert scale in condition after the program. This scale was collapsed to produce 
      a dichotomous variable outcome: improved and non-improved. Responsiveness was 
      determined using effect size statistics and receiver operating characteristic 
      curve (ROC curve), with best cut-point analysis. The best change score cut-off 
      was identified when equally balanced sensitivity and specificity was found, as an 
      expression of the minimum clinically important difference (MCID). After 
      treatment, 19 patients considered themselves improved. Both the effect size 
      (0.37) and the area under the ROC curve (0.73) for ODI-Brazil score in relation 
      to global outcome after program indicated that the ODI-Brazil showed 
      responsiveness. The ROC curve for ODI-Brazil was distributed at the upper corners 
      of the diagonal line, indicating that the questionnaire presents discriminative 
      ability. The best cut-off point for ODI-Brazil was approximately 4.45 points 
      (63.2% sensitivity, 81.8% specificity). The Brazilian-Portuguese version of ODI 
      has comparable responsiveness to other commonly used functional status measures 
      and is appropriate for use in chronic low back pain patients receiving 
      conservative care.
