Summary

This is a multi-site collaborative study that will be done in the context of three Quebec hospitals' outpatient pulmonary rehabilitation programs: Montreal Chest Institute; University of Laval, and Hopital Sacre-Coeur Montreal. The objectives are two-fold. First, to determine the Minimal Clinical Important Difference in intensity ratings of perceived breathlessness for each of the 3-min constant rate shuttle walking (3-MWT) and stair stepping (3-MST) protocols in patients with chronic obstructive pulmonary disease (COPD). Second, to test the hypothesis that both the 3-MWT and 3-MST protocols are able to detect statistically significant and clinically-meaningful improvements in exertional breathlessness following an 7-12 week outpatient rehabilitative exercise training program in COPD.

Conditions

• Pulmonary Disease, Chronic Obstructive

Interventions

Type	Name	Description
OTHER	Pulmonary Rehabilitation	Patients will participate in 3 exercise training sessions/wk for a period of 7-12 wks at one of 4 sites in Quebec. Each training session will include 30-45 min of aerobic training (cycling and/or treadmill walking) at a target intensity of 80% of the maximal heart rate achieved during a symptom-limited incremental cycle exercise test performed prior to the pulmonary rehabilitation program; and 20-30 min of strength training exercises.
