“…This is confirmed in most studies in the literature, in which incremental tests such as the SWT have been shown to induce greater increases in cardiovascular variables when compared to the 6MWT. (9)(10) In a recent study, similar results in the cardiovascular parameters were reported for the SWT and the 6MWT. However, the study sample was composed of patients with COPD recovering from exacerbations, and the unencouraged form of the 6MWT was used.…”

“…The test should be carried out until the point of exhaustion (Chart 1). The SWT is simple, with good reproducibility, and is based on walking on any flat surface; it requires no specific ergometers; (9)(10) it is used as an outcome measure in the evaluation of various interventions used for COPD patients. (9,(11)(12)(13)(14) Regarding exercise tolerance, this test has shown good correlation between the walking distance and peak oxygen consumption at the end of the test (r = 0.81), which is similar to that obtained in maximal treadmill stress tests (r = 0.88).…”

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 random order, patients were, after an initial practice period, submitted 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.

“…This indicates that, for this population, the test is reproducible with reproducibility values similar to those obtained using other clinical exercise tests, such as 6-min walk test, which presents an ICC of 0.88 -0.94, [20][21][22] and shuttle-walk test, which presents an ICC of 0.87. 23 Moreover, the error value for this comparison was acceptable, presenting a mean error of 5.7 steps and limits of agreement ranging from Ϫ7.1 to 18.6 steps. Dal Corso and colleagues 7 also concluded that this test is reproducible in subjects with interstitial pulmonary fibrosis with even lower error values (mean error of one step and limits of agreement ranging from Ϫ0.5 to 2.5 steps).…”

Reproducibility of Cadence-Free 6-Minute Step Test in Subjects with COPD

et al. 2013

BACKGROUND: Six-minute step test (6MST) has been used to assess functional capacity in chronic conditions; however, its reproducibility in the COPD population has not been evaluated. Our study objective was to evaluate 6MST reproducibility. METHODS: The test was performed in a single 20-cm height step, and subjects were instructed to step up and down (cadence-free) for 6 min. Subjects underwent three tests. The first and second were controlled by the same assessor with a 30-min interval. The third test was controlled by a different assessor one week later. For intrarater comparison, the first and second performances of the test were used, and for inter-assessor comparison, the better performance of the first two tests was compared with the third test. RE-SULTS: Excellent intra-rater and inter-rater relative reproducibility was observed (intraclass correlation coefficient > 0.8), and there was no statistical difference (repeated measures of analysis of variance) among the performances of the three tests. Intra-rater error values were acceptable (mean error of 5.7 steps and limits of agreement between ؊7 and 18 steps). Inter-rater error values were not acceptable (mean error of 4.4 steps and limits of agreement between ؊20 and 29 steps. CONCLUSIONS: 6MST proved to be reproducible in the COPD population when performed by the same assessor.
