Abstract
Background: The 5STS is a test of lower limb function that measures the fastest time taken to stand up and sit down from a chair five times without use of the upper limbs. It has been validated in COPD, but data in bronchiectasis is lacking.
Aim: To determine the validity and responsiveness of 5STS in patients with bronchiectasis.
Methods: 5STS, incremental shuttle walk test (ISW), MRC dyspnoea score (MRC), and Chronic Respiratory Questionnaire (CRQ) were measured in 133 patients with bronchiectasis before and after 8-weeks of outpatient pulmonary rehabilitation (PR).
Results: Baseline characteristics and change with PR are presented in Table 1. At baseline there was a significant correlation between 5STS and MRC, ISW and CRQ-fatigue (r=0.34, -0.56, -0.23 respectively). Following PR, there were significant improvements in 5STS, ISW, CRQ-total and MRC with an effect size of 0.48, 0.55, 0.25 and 0.39 respectively. Change in 5STS with PR did not correlate with change in ISW, CRQ or MRC.
Conclusion: 5STS is responsive to PR in patients with bronchiectasis with an effect size of 0.48. Change in 5STS did not correlate with changes in other outcome measures and may therefore provide additional information to traditional PR outcome measures.
