Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators will perform two cross-sectional studies for validity and reliability in patients with COPD. Participants attending a pneumology consultation at the hospital will be asked for permission to be contacted about the study. The participants who agree will be seen by the principal investigator who will explain the nature of the study and assess eligibility for the study. The participants will sign informed consent.
The validity study will be performed in two days (separated \>48h). During the first session, the participants will perform the 6-minute walk test (6MWT) twice (a valid test for COPD). On the second day, the step test will be performed twice.
The reliability study will be performed in two days (separated for 7 days). On both days, the step test will be performed one time.
The investigators predict that 50 patients with COPD will be followed in each study (validity and reliability).
The investigators hypothesize that the step test can be a good option to apply in pulmonary rehabilitation programs with good measurement properties for the assessment of exercise capacity in COPD patients. The validation of the test can contribute to applying the step modality in the exercise training as an alternative for the prescription of the exercise intensity. For that, the investigators also hypothesize that the test can be reliable and one test must be enough for the assessment of the patients.

COPD patients
Performance of step test (number of steps) for the assessment of exercise capacity
The development of the step test will be designed according to the characteristics of other validated field tests - the walking tests (6-minute walk test and the incremental shuttle walking test) The step test will be performed on a 20 cm tall, single-step device with no handles. The criteria for stopping the test will be the same as described in standard operating procedures for the walking field tests, with the addition of the inability to follow the work rate for a period of 10 seconds.
The main outcome of the test will be the highest number of steps and work rate achieved.
