6-minute Stepper Test and Pulmonary Rehabilitation in Patients With Chronicle Obstructive Pulmonary Disease

Use of the 6-minute Stepper Test to Individualise Pulmonary Rehabilitation in Patients With Mild to Moderate Chronicle Obstructive Pulmonary Disease

The purpose of this study is to determine, if it exists, a relation between plateau heart rate from the last 3 minutes of the 6-minute stepper test and heart rate from first ventilatory threshold from cardiopulmonary exercise testing in order to individualise pulmonary rehabilitation in patients with mild to moderate chronicle obstructive pulmonary disease.

Inclusion Criteria:

• Age > 18 ans ;
• Chronicle obstructive pulmonary disease stage I/II (FEV1 ≥ 50%) ;
• Chronicle obstructive pulmonary disease stage III/IV (FEV1 < 50%) from may 2019 (ethical approvement granted)
• Weight ≤ 90kg ;
• Eligible for pulmonary rehabilitation.

Exclusion Criteria:

• Pregnant woman or likely to be ;
• Patient under guardianship ;
• Contraindication to cardiopulmonary exercise testing ;
• Patient medically treated with heart rate modulator (excluding oral B2-agonist) ;
• Patient treated with pacemaker or defibrillator ;
• History of lower limb impairment (i.e. peripheral artery disease, orthopedic disorder etc.).
