spelling	Theoretical frame: it has been reported that involuntary stops during the six-minute walk test are associated with increased mortality in patients with chronic obstructive pulmonary disease. However, the relationship between the stops and other determinations of the six-minute walk test, such as speed, work, the distance-saturation product, and exercise-induced desaturation, has not yet been established.Objectives: to determine the correlation between involuntary stops and clinical variables gathered routinely in the six-minute walk test, as well as the new determinations derived from the test, in patients with chronic obstructive pulmonary disease.Materials and methods: an observational, analytic, retrospective study was carried out, in which the reports of six-minute walk tests from 129 subjects with chronic obstructive pulmonary disease were reviewed. The determinations derived from the test were compared between the patients who had stops and those who hadn’t; correlations between them were made, and predictors of stops were identified by logistic regression anaylysis.Results: 30 patients had involuntary stops during the test; in this group, it was observed in the end that scores of dyspnea and fatigue, as well as heart rate, respiratory rate, and final systolic arterial blood pressure were significantly higher than those found in the group that did not have stops, while arterial blood oxygen saturation was significantly lower (p&lt;0,001); the new variables derived: distance, speed, work, and the distance-saturation produc were lower (p&lt;0,001) in the subjects who stopped; a good correlation with them was found. On regression analysis, the variables that remained significant for the presence of stops were: final saturation, distance walked, speed, work,DDR, and distance-saturation product.Conclusions: in patients with stable chronic obstructive pulmonary disease who undergo the six-minute walk test, stops are associated with less distance walked, work, DSP, and saturation at the end of the test. Calculation of these new variables, together with registration of stops during the six-minute walk test, might refine the prognostic capability of the test in patients with chronic obstructive pulmonary disease.
