Study Overview
Brief Summary
This is a study to provide an in-depth validation of the 1-minute sit-to-stand test as a measure of exercise capacity in patients with chronic obstructive pulmonary disease (COPD). Patients will perform the 1-minute sit-to-stand test and other validated exercise tests and questionnaires.
Detailed Description
Exercise capacity is a strong predictor for mortality, exacerbations and health-related quality of life (HRQL) in patients with chronic obstructive pulmonary disease (COPD). The 1-minute sit-to-stand test (1-min STS test) is a promising exercise capacity test that is simple to conduct and requires few resources.
This study will provide an in-depth validation of the 1-min STS test, specifically evaluating the tests reliability, validity, responsiveness to change and minimal clinically important difference. The study will also assess the predictive properties of the 1-min STS test with regards to detecting exacerbations, as well as identify patterns of physical activity and patient-reported symptoms of exacerbations.
