Study information
Scientific title
The effects of maintenance schedules following pulmonary rehabilitation in patients with chronic obstructive pulmonary disease
Acronym
Study hypothesis
The primary aim is to compare the effectiveness of maintenance pulmonary rehabilitation (PR) sessions at 3, 6 and 9 months following a PR course compared to standard care in a randomised prospective study of patients with chronic obstructive pulmonary disease (COPD). This will be assessed, at 12 months following the initial course, in terms of disease specific health related quality of life as assessed by the dyspnoea domain of the chronic respiratory questionnaire, shuttle walk test, muscle strength, fat free mass, anxiety and depression scores, and exacerbation frequency.

2. Physician labelled diagnosis of COPD, emphysema or chronic bronchitis
3. Ex or current smoker of more than 20 pack years
