6-minute Stepper Test, Chronic Obstructive Pulmonary Disease, Pulmonary Rehabilitation
Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Relation between plateau heart rate (bpm) from the first and last 3 minutes of the 6-minute stepper test and heart rate (bpm) from first ventilatory threshold from cardiopulmonary exercise testing. | Heart rate (bpm) will be assessed during cardiopulmonary exercise testing with electrocardiogram. During the 2 6-minute stepper test, heart will be assessed with oximeter. All theses tests wil be carried out in a total time frame of 3 month maximum. | Outcome (heart rate) during different tests will be continuously recorded. Relation will be adjusted for age and step count. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Relation between minimal SpO2 (%)from the 6-minute stepper test and SpO2 (%) from first ventilatory threshold from cardiopulmonary exercise testing. | SpO2 will be assessed with oximeter. All theses tests wil be carried out in a total time frame of 3 month maximum. | Outcome (SpO2 (%)) during different tests will be continuously recorded. Relation will be adjusted for age en step count. |
| Blood pressure (mmHg) before and after every 6-minute stepper test using electrical blood pressure device. | The outcome will be assessed before and after every 6-minute stepper test. The 2 6-minute stepper test will be carried out the same day (minimum 20 minute of rest between each test) for a total time frame of 1 day. | — |
| Steps during 6-minute stepper test using stepper device. | The 2 6-minute stepper test will be carried out on the same day (20 minute of rest between each test) for a total time frame of 1 day. | — |
