Brief summary
Short term efficacy of pulmonary rehabilitation for improving functional capacity and quality of life of chronic obstructive respiratory disease (COPD) patient is well known. However, there is an important gap between the scientific knowledge and the clinical use of pulmonary rehabilitation since a a very small number of patients benefit from this therapeutic intervention. We estimate that less than 1% of the 750 000 canadians suffering from COPD have access to a pulmonary rehabilitation program. We want to study the efficacy of a home-based rehabilitation program as a way to facilitate the access to rehabilitation.

Interventions
BEHAVIORALPulmonary rehabilitation (teaching and exercise)
After a 4-week education program, patients took part to home-based rehabilitation or outpatient hospital-based rehabilitation for 8 weeks. Patients were subsequently followed for 40 weeks to complete the one-year study.

Defined as a 6MWD greater than 110 meters. * Subject is diagnosed with COPD. * 40 years-old and older * Currently or previously smoking with a smoking history of at least 10 pack-years. * Forced expiratory volume on one second (FEV1) after the use of a bronchodilator between 25 an 70% of the predicted value, and FEV1 to forced vital capacity ratio less than 70%. * No previous diagnosis of asthma, left heart congestive heart failure (either radiographic evidence of pulmonary congestion, echocardiographic or ventriculographic evidence of a reduced ventricular ejection fraction), terminal disease, dementia or uncontrolled psychiatric illness. * Never participated to a respiratory rehabilitation program and not staying or planning to stay in a long term care facility. * Subject understands and is able to read and write French or English. * MRC dyspnea scale of at least 2.
Exclusion criteria
* The need for supplemental oxygen at rest or during exercise will not be an exclusion criterion.
