The purpose of this study was to evaluate the performance in the 6-minute walk
test (6 MWT) of elderly patients with chronic obstructive pulmonary disease
(COPD) by comparing to a group of healthy elderly patients, performed with and
without verbal encouragement. This cross-sectional study compared 40 patients
with COPD (forced expiratory volume in the first second (FEV1%) = 53.7 +/- 23.8%;
forced vital capacity (FVC%)
= 65.5 +/- 20.8%; and the FEV1/FVC ratio = 55.4 +/-
12.4) and 40 healthy elderly patients (control). The 6 MWT's were performed with
and without verbal encouragement according to the American Thoracic Society
(ATS), monitoring the distance walked (6 MWD), the duration of walking (TW) and
the perceived effort index (PEI) through the Borg scale between the groups. No
differences were observed in patients with COPD when the tests were performed
with and without verbal encouragement for the 6 MWD, TW and PEI, the same
occurring in the control group for the 6 MWD, TW and PEI, respectively. The use
of verbal encouragement was not sufficient to promote improvement in the
performance of the 6 MWT (6 MWD, TW and PEI) of patients with COPD and healthy
elderly patients.
