Intrarater reliability of Timed Up and Go Test to patients with COPD

Abstract

INTRODUCTION: The Timed UP and Go Test (TUG) is an important test used to assess functional outcomes in COPD, such as mobility, dynamic balance, and risk of falling. In clinical practice, the repeated application of the TUG is performed several times by the same observer to evaluate different interventions applied in COPD. OBJECTIVE: To assess the degree of intraobserver reproducibility of TUG in individuals with COPD. METHODOLOGY: Descriptive, cross-sectional study carried out with individuals with COPD treated in an outpatient clinic in the city of Salvador-Bahia. Sociodemographic and clinical characteristics such as spirometry (FEV1/FVC) were verified, as well as two practices of the TUG Test on the same day. The reproducibility of TUG was evaluated fur Intraclass Correlation Coefficient (ICC). CAAE number 38143214.0.0000.0057. RESULTS: Thirty-one volunteer patients were evaluated, of which 24 (77.4%) men, mean age 68.6 ± 9.8 years, with post-bronchodilator FEV1//FVC ratio 59.0 ± 10.8%. In the analysis of intraobserver reproducibility of the TUG by the ICC, ? = 0.897 (CI 95%: 0.786; 0.950; p < 0.0001) was obtained. CONCLUSION: The TUG test has excellent intraobserver reproducibility and a small variability when applied twice in patients with COPD, being the application for mobility assessment, in care practice, considered viable.
