Abstract

PURPOSE: The aim of this study was to evaluate 6MWT distance (6MWD) in COPD patients, to compare it to reference values and to establish correlation with spirometric parameters.

METHODS: Forty three patients with moderate COPD (age 64,60&±61617;7,92; 29 male) volunteered and completed the testing sequence, wich included pulmonary function (basal and pos- bronchodilator spirometric) and 6MWT. The 6MWT was done following ATS norms, with verbal incentive from researcher who walked side by side with patient. Reference values for 6MWD were calculated from Enright & Sherril formula. Correlations between the 6MWD and spirometric measurements were generated by non-parametric Spearman Test, with level of significance set at 0,05.

RESULTS: The mean ( ± SD) 6MWD values were 478,9 ± 99,2 meters, wich represent a 95,3% of estimated distance for these patients 511,2±± 85,2 meters. Significant correlation was found between 6MWD, absolute mean ( ± SD) values and mean ( ± SD) percent of predicted for VC and FVC, but not for FEV1 and inspiratory capacity. Table1.

CONCLUSION: We founded significant correlation between some of spirometric parameters and 6MWD for this COPD patients population studied.

CLINICAL IMPLICATIONS: The Six Minute Walk Test (6MWT) is commonly used to asses aerobic exercise capability in patients with chronic obstructive pulmonary disease (COPD) and avaluate functional of cardiovascular and respiratory systems. COPD patients show reduction in physical capacity due to dynamic hyperinflation, glicolytic muscular metabolism, unfittness and sedentary life wich, with disease progression, will deteriorate their life quality and limit the social and physical activities.
