      With Non-Cystic Fibrosis Bronchiectasis.

AB  - PURPOSE: The 6-Minute Walk Test (6MWT) and Incremental Shuttle Walk Test (ISWT) 
      are used to assess exercise capacity, but the reliability and responsiveness of 
      these tests in individuals with non-cystic fibrosis (CF) bronchiectasis have not 
      been determined. This study aimed to determine the reliability and responsiveness 
      of both tests in adults with non-CF bronchiectasis. METHODS: Eighty-five 
      participants completed 2 6MWTs and 2 ISWTs in random order. Testing was repeated 
      at the conclusion of an 8-week intervention period of exercise training. 
      Reliability was assessed using intraclass correlation coefficients (ICC) and 
      Bland-Altman analysis. Responsiveness was measured by effect size (ES) and 
      standardized response mean (SRM). RESULTS: At baseline, test-retest reliability 
      was high for both tests (ICC >/= 0.95). The mean (95% CI) increase in the 6MWT from 
      test 1 to test 2 was 20 m (13-26 m): 3% (0-5%) change. The mean (95% CI) increase 
      in the ISWT was 15 m (4-25m): 4% (2-6%) change. A significant learning effect 
      persisted after 8 weeks for the 6MWT (P = .04), but not the ISWT (P = .61). The 
      6MWT ES was 0.32 and SRM was 0.68; for the ISWT, ES was 0.42 with SRM of 0.71. 
      CONCLUSION: The 6MWT and ISWT are reliable measures of exercise capacity in 
      non-CF bronchiectasis and responsive to exercise training. The small learning 
      effect in both measures at baseline suggests that 2 of each test are necessary to 
      correctly assess exercise capacity. Completion of 2 6MWTs at followup may 
      minimize the risk of underestimating a treatment effect.
