For logistical purposes, the study is divided into two work packages (WP): 1) Pilot study of DirectLife activity monitor in the daily routine of patients with COPD (WP1), which is a cross-sectional study; 2) Physical activity enhancing programme - main project (WP2), which is a randomized controlled trial. Both studies will be performed at Leith's Community Treatment Centre (LCTC) and its satellites (Midlothian Community Hospital (Bonnyrigg) & St Johns Hospital (Livingston) - Edinburgh). Only patients with COPD referred to pulmonary rehabilitation at LCTC and its satellites will be recruited for this study. The standard care treatment (exercise training) is exactly the same in all sites, and it is delivered by the same team of physiotherapists.At the satellite units it would still be the direct care that approach the participants. The recruiting procedure will be the same as that of the original study.
