NCT ID: NCT04008615 Recruiting - Clinical trials for Chronic Obstructive Pulmonary Disease

Comparison of the Cardiopulmonary and Gaz-exchange Response Between the Six-minute Stepper Test and the Incremental Cardiopulmonary Exercise Testing in Patients With Chronicle Obstructive Pulmonary Disease

PH-6MST
Start date: August 1, 2019
Phase:
Study type: Observational

Chronicle obstructive pulmonary disease is a worldwide cause of mortality and morbidity. This systemic disease progressively leads to dyspnea, muscle wasting and exercise capacity impairment. Pulmonary rehabilitation is a cornerstone in the management of these systemic effects. Unfortunately, access to pulmonary rehabilitation is limited for many people who would benefit from it, primarily because of a lack of pulmonary rehabilitation and assessment centers. Optimal assessment should include an incremental cardiopulmonary exercise testing. This test allows to evaluate the factors contributing to exercise intolerance by linking performance and physiological parameters to the underlying metabolism. Moreover, it is the standard test to determine both the optimal training settings as well as any cardiopulmonary contraindications to pulmonary rehabilitation. However, this test is not available in most centers and when it is, consultations are limited. Therefore, pulmonary rehabilitation is often delayed for several weeks and patients can lose motivation. In order to promote pulmonary rehabilitation, the incremental cardiopulmonary exercise testing could be replaced by field tests to individualize pulmonary rehabilitation prescription. The six-minute stepper test is a new field tool. Its sensitivity and reproducibility have previously been reported in patients with chronicle obstructive pulmonary disease. It is easy to set up in the clinical setting and could be used to individualize pulmonary rehabilitation. The main drawback when using field test is that they only provide a non specific assessement of the functional capacity because cardiopulmonary parameters and gaz exchanges are not monitored. Although the performance during the 6-minute stepper test is moderately related with the maximal oxygen consumption during the incremental cardiopulmonary exercise testing performed on a cycloergometer, a direct comprehensive comparison of cardiopulmonary parameters and gaz exchanges during these two tests have never been performed. Moreover, stepping is more closely related with activities of daily life (requiring a repetitive transition from rest to submaximal exercise intensity) than the maximal incremental exercise on cycloergometer and could provide further insight on the disability of patients during their usual activities, such as stair climbing (which is frequently avoided). Additionally, on-transient phase two oxygen consumption kinetic is particularly relevant because it evaluation is independent of the patient's motivation or criteria used to terminate exercise. Therefore, the aim of this study is to compare the cardiorespiratory parameters, the gaz exchanges and the maximality between the six-minute stepper test and the incremental cardiopulmonary exercise testing performed on a cycloergometer. The secondary objective was to compare the on-transient oxygen consumption phase two kinetic parameters (time constant, span and steady state) according to the severity of the disease.

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

The 6-minute stepper test is a new field tool. Its sensitivity and reproducibility have previously been reported in patients with chronicle obstructive pulmonary disease. It is easy to set up in the clinical setting and could be used to individualize pulmonary rehabilitation. The aim of this study was to develop and validate a prediction equation to set rehabilitation intensity for patients with severe to very severe chronicle obstructive pulmonary disease attending pulmonary rehabilitation, with the use of a simple, readily available field test. Therefore the investigators sought to determine, if it exists, a relationship between the plateau heart rate from the first and last 3 minutes of the 6-minute stepper test and the heart rate from the first ventilatory threshold from the cardiopulmonary exercise testing in order to individualize pulmonary rehabilitation in patients with severe to very severe chronicle obstructive pulmonary disease.

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

6STaR
Start date: July 2016
Phase:
Study type: Observational

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.
