AB  - OBJECTIVES: To examine the incidence of resting during the 6-minute-walk test 
      (6MWT) in patients with chronic lung disease (CLD) and to explore differences in 
      functional exercise capacity and response to pulmonary rehabilitation (PR) 
      between resters and nonresters. DESIGN: Retrospective chart review. SETTING: 
      Inpatient PR program. PARTICIPANTS: Individuals (N=211) who performed the 6MWT at 
      admission and discharge from PR. INTERVENTIONS: Not applicable. MAIN OUTCOME 
      MEASURES: Primary outcomes were total distance walked (6-minute walk distance 
      [6MWD]) and rest frequency and duration. Secondary outcomes were walking speed, 
      end-test dyspnea, and the Chronic Respiratory Questionnaire (CRQ). RESULTS: At 
      admission, 45 people (21%) rested 1 to 4 times during the 6MWT (total duration, 
      105+/-80s) and 166 people walked continuously. At discharge, 9 people continued to 
      rest (total duration, 28+/-55s). At admission, nonresters walked 315+/-93m, whereas 
      resters walked 197+/-83m (P<.0001), and 6MWD increased in both groups after PR 
      (P<.0001). Nonresters increased their walking speed at discharge, but resters did 
      not (interaction P<.001). At admission, the mastery domain of the CRQ was 0.8 
      point lower in resters (3.7+/-1.2) compared with nonresters (4.5+/-1.7; P=.01). 
      Resters' end-test dyspnea scores decreased from 5.7+/-0.3 to 4.3+/-0.2 from admission 
      to discharge, whereas nonresters' end-test dyspnea scores did not significantly 
      change from 4.5+/-0.2 to 4.2+/-0.2 at discharge (interaction P<.05). CONCLUSIONS: One 
      in 5 individuals with CLD rest during the 6MWT. Decreasing rest duration or 
      increasing walking speed reflects different strategies used to improve 6MWD after 
      rehabilitation, both suggesting a positive effect of PR. This may be related to 
      improvements in an individual's sense of control over dyspnea. Future work should 
      investigate potential factors related to resting during the 6MWT.
