Evaluating physical capacity in patients with chronic obstructive pulmonary disease: comparing the shuttle walk test with the encouraged 6-minute walk test.
OBJECTIVE To evaluate the applicability of the incremental ( shuttle ) walk test in patients with chronic obstructive pulmonary disease and compare the performance of those patients on the shuttle walk test to that of the same patients on the encouraged 6-minute walk test . METHODS A cross-sectional study was conducted , in which 24 patients with chronic obstructive pulmonary disease were selected . In r and om order , patients were , after an initial practice period , su bmi tted to a shuttle walk test and an encouraged 6-minute walk test . RESULTS The patients obtained a higher heart rate ( expressed as a percentage of that predicted based on gender and age ) on the encouraged 6-minute walk test ( 84.1 + /- 11.4 % ) than on the shuttle walk test ( 76.4 + /- 9.7 % ) ( p = 0.003 ) . The post-test sensation of dyspnea ( Borg scale ) was also higher on the encouraged 6-minute walk test . On average , the patients walked 307.0 + /- 89.3 meters on the shuttle walk test and 515.5 + /- 102.3 meters on the encouraged 6-minute walk test ( p < 0.001 ) . There was a good correlation between the two tests in terms of the distance walked ( r = 0.80 , p < 0.001 ) . CONCLUSION The shuttle walk test is simple and easy to implement in patients with chronic obstructive pulmonary disease . The encouraged 6-minute walk test produced higher post-test heart rate and greater post-test sensation of dyspnea than did the shuttle walk test
