The significant correlations between the 2MWT and the 6MWT, V02max, and V02max/kg support the validity of the 2MWT as a measure of exercise capacity in COPD patients with moderate-to-severe disease. As anticipated, the strongest correlation was observed between the 2MWT and 6MWT, since they are both walking tests and their results were in agreement with […]
Part 2 of this study investigated the responsiveness of the 2MWT as a measure of change following a 5-week pulmonary rehabilitation program. Of the 15 subjects recruited to this program, 3 subjects dropped out due to poor motivation and 3 subjects failed the postassessment review due to acute exacerbations. Therefore, data from nine subjects (mean […]
Of the 47 subjects who were initially recruited to the study, two subjects dropped out because they had exacerbations during the assessment period. Demographic and anthropomorphic data, and pulmonary function test and exercise test results are shown in Tables 1, 2. Forty-five subjects (37 men and 8 women; mean age, 71.8 ± 8.3 years; mean […]
ECG activity was monitored continuously, and systemic arterial BP was registered every 2 min. Subjects were asked to quantify their perceived dyspnea and exertion by pointing at a 10-point modified Borg scale before and at the termination of the test. Wmax (measured in Watts) was defined as the highest work level reached, and Vo2max (measured […]
