Functional Capacity
Both 5STS-test and MSWT were performed twice on the same day (test and retest), with an interval of 30 minutes between them. The 5STS-test was performed with the subject sitting on a chair with his arms crossed over his chest. The patient should perform five movements of getting up and sitting down as quickly as possible. The height of the chair was adjusted to reach the angle of flexion of the hips and knees at 90ยบ and feet flat on the floor. The test outcome was the execution time in seconds (s).18
The MSWT was performed in a 10 m long corridor according to the original description19. It is a test externally paced by an audible signal, in which the speed increases every minute, varying from 1.79 to 10.2 km / h.20 The test ends when the volunteer is unable to follow the speed or needs to stop the test due to fatigue, dyspnea or when SpO2 remains below 82%. The outcome is the distance walked in meters and the percentage of the predicted value.21
The order of the tests (MSWT and 5STS-test) was randomized. Heart rate (HR), dyspnea and lower limb fatigue (modified Borg scale22) were assessed at the beginning and at the end of all the tests.
