Overview
Brief Summary
This study is designed to determine the individual threshold of minimal clinical change (MCID) for each component of the Multidimensional Dyspnea Profile (MDP) questionnaire in COPD patients undergoing pulmonary rehabilitation.
Detailed Description
The aim of the research is to determine the minimal clinically significant difference (MCID) in MDP scores in COPD patients after a respiratory rehabilitation course using the anchoring method : * The A1 score will be compared with the Borg Affective Dyspnea (BorgA) scale. * The sensory score will be compared with the Borg Sensory Dyspnea Scale (BorgS). * The 5 sensory items will be compared with the Borg Sensory Dyspnea scale. * The emotional score will be compared with the Borg Emotional Dyspnea Scale. * The 5 emotional items will be compared with the Borg affective dyspnea scale. The various questionnaires will be administered to patients at inclusion, after a constant work-rate cycling exercise test, and at isotime during the same cycling exercise test at the end of the pulmonary rehabilitation course. The sensitivity study will be conducted using the visual analog dyspnea scale instead of the Borg score. Finally, we will also determine the MCID using the distribution method. The MCID score will be correlated with various quality of life and physical performance scores.

Outcomes
Primary Outcomes
sensory Borg scale
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
The two Borg scales will be carried out at the end of the constant work-rate cycling exercise test, taking into account the last 30 seconds.
multidimensional (MDP) questionnaire
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
The multidimensional questionnaire measuring the sensory component of dyspnea (intensity of the 5 respiratory descriptors) and the affective component of dyspnea (immediate discomfort and intensity of emotional responses). The MDP will be carried out at the end of the constant work-rate cycling exercise test, taking into account the last 30 seconds.
affective Borg scale
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
The two Borg scales will be carried out at the end of the constant work-rate cycling exercise test, taking into account the last 30 seconds.
