Abstract
Background: The 6-minute walk test (6TC) was initially used as an instrument for assessing physical and cardiorespiratory capacity, but is currently being used to monitor treatments, and compare physical interventions and prognostic evaluation. Although already recognized as a research method in several specialties, 6TC has not been used in rheumatology. Patients with rheumatoid arthritis (RA) may have impaired functional capacity as well as increased cardiovascular mortality. An adequate functional evaluation of these patients is necessary and the 6TC may be useful in this sense. Objective: The aim of this study was to perform the 6-minute walk test in RA patients and to compare the performance with a control group. Method: A cross-sectional study was carried out in which the sample consisted of 85 women, 46 patients with rheumatoid arthritis and 39 healthy controls. A descriptive analysis of the data was performed. One-Way ANOVA methodology was used to compare the patient and control groups followed by the graphic analysis. Results: The distance walked on the 6TC by RA patients was on average 522.2 meters. In the distance control group found in the 6TC was on average 628.8 meters, the difference being statistically significant. Conclusion: In this study the distance covered in 6TC by women with RA was lower than that of healthy women of the same age.
Highlights
The walk test was originally developed by Cooper as a measure of the level of physical activity of US military soldiers
Brasília Cohort [15]-[21] is an incident cohort of patients diagnosed with rheumatoid arthritis (RA), followed at the Rheumatology outpatient clinic of the University Hospital of Brasília (HUB), University of Brasília (UnB)
The patients were evaluated at the Laboratory of Aptitude and Rheumatology (LAR) of UnB
Summary
The walk test was originally developed by Cooper as a measure of the level of physical activity of US military soldiers. McGavin et al [2] modified the test using the 12-minute walk instead of running to examine patients with chronic bronchitis. It was initially used as an instrument for the evaluation of physical and cardiopulmonary capacity, it has been used to monitor several treatments, to compare physical interventions and even to evaluate prognosis [5]. Objective: The aim of this study was to perform the 6-minute walk test in RA patients and to compare the performance with a control group. Conclusion: In this study the distance covered in 6TC by women with RA was lower than that of healthy women of the same age
