Reanalysis of the 12-Minute Walk in Patients With Chronic Obstructive Pulmonary Disease – Conclusion
It has been shown that the 12-min walking test does not correlate significantly with FEV, but there have been differing results as to whether it does2 or does not correlate with FVC. Our results support the latter finding (r = -0.16). In addition, we found that there was a significant correlation between changes in the FEVj and changes in the 12-min (r = 0.53) and changes in the 6-min (r = 0.53) walking tests.
Previous studies, as well as our own, demonstrate that the results of walking tests correlate with functional capacity as assessed by symptom-limited maximal exercise tests. However, in assessing the effects of an intervention for a given individual, it is more important to understand how changes in walking test performance correlate with the changes in the maximum exercise capacity. It would be advantageous to be able to predict the change in Vo2max, that a patient is experiencing since his last examination from his walking test alone because it precludes the necessity of using more complicated apparatuses such as a treadmill or bicycle ergometer. canadian neightbor pharmacy
