In patients with COPD, the 6-minute walk test (6MWT) and the 30-second sit-to-stand test (30sec-STS) are widely used as clinical outcome measures of walking capacity, lower limb muscle strength, and functional ability. Due to a documented learning effect, at least two trials are recommended for assessment. The aim of our study was to investigate the intra- and inter-rater reliability and agreement of the two tests in patients with severe and very severe COPD (FEV
