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

ADIR Association105 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.

Outcome (heart rate) during different tests will be continuously recorded. Relation will be adjusted for age and step count.

Time frame: 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.

Secondary Outcomes

Relation between minimal SpO2 (%)from the 6-minute stepper test and SpO2 (%) from first ventilatory threshold from cardiopulmonary exercise testing.

Outcome (SpO2 (%)) during different tests will be continuously recorded. Relation will be adjusted for age en step count.

Time frame: SpO2 will be assessed with oximeter. All theses tests wil be carried out in a total time frame of 3 month maximum.

Blood pressure (mmHg) before and after every 6-minute stepper test using electrical blood pressure device.

Time frame: 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.

Time frame: 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.
