TI  - Responsiveness and Minimal Clinically Important Difference of the Brief-BESTest 
      in People With COPD After Pulmonary Rehabilitation.

AB  - OBJECTIVE: he Brief-Balance Evaluation Systems Test (Brief-BESTest) is a 
      comprehensive, reliable, and valid balance test that provides valuable 
      information to guide balance training in people with chronic obstructive 
      pulmonary disease (COPD). Its clinical interpretability is, however, currently 
      limited, because cutoff points to identify clinically relevant changes in people 
      with COPD after pulmonary rehabilitation are still lacking. This study aimed to 
      establish the responsiveness and minimal clinically important difference (MCID) 
      for the Brief-BESTest in people with COPD after pulmonary rehabilitation (PR). 
      METHODS: A secondary analysis of data from 2 previous studies was conducted. The 
      modified British Medical Research Council (mMRC) dyspnea scale, the 6-Minute Walk 
      Test (6-MWT), and the Brief-BESTest (0-24 points) were collected in people with 
      COPD pre/post a 12-week PR program including balance training. The MCID was 
      computed using anchor- and distribution-based methods. Changes in the 6-MWT and 
      the mMRC were assessed and used as anchors. The pooled MCID was computed using 
      the arithmetic weighted mean (2/3 anchor- and 1/3 distribution-based methods). 
      RESULTS: Seventy-one people with COPD (69 years [SD = 8]; 76% male; 
      FEV1 = 49.8%predicted [SD = 18%]) were included. There was a significant 
      improvement in the Brief-BESTest after PR (mean difference = 3 points [SD = 3]). 
      Significant correlations were found between the Brief-BESTest and the mMRC 
      (r = -.31) and the 6-MWT (r = .37). The pooled MCID was 3.3 points. CONCLUSION: 
      An improvement of at least 3 points in the Brief-BESTest in people with COPD will 
      enhance the interpretability of PR effects on balance performance of this 
      population and guide tailored interventions. IMPACT: The Brief-BESTest outcome 
      measure is comprehensive, easily administered, and simple to interpret in 
      clinical practice. This study represents a significant contribution toward the 
      clinical interpretation of changes in balance in people with COPD following PR.
