Effect of a pulmonary rehabilitation programme of 8 weeks compared to 12 weeks duration on exercise capacity in people with chronic obstructive pulmonary disease (PuRe Duration): protocol for a randomised controlled trial

摘要

Pulmonary rehabilitation (PR) is a key component in the management of chronic obstructive pulmonary disease (COPD). There is no strong evidence on the optimal duration of PR programmes. The aim of this study is to determine whether an 8-week PR programme is equivalent to a 12-week PR programme in people with COPD.
