ANGARITA FONSECA, Adriana et al. Reproducibility of a test for the functional evaluation of dynamic balance and agility in elderly people. Iatreia [online]. 2014, vol.27, n.3, pp.290-298. ISSN 0121-0793.

Background: The 8 foot up & go test assesses the dynamic balance and agility in elderly people. Its reproducibility has been evaluated in American population, but it is unknown whether it would work similarly in a different population like the Colombian. Objective: To evaluate the test-retest reliability and agreement level of the 8 foot up & go test in a sample of older adults from Bucaramanga, Colombia. Materials and methods: An evaluation of diagnostic tests was done in 114 elderly individuals. In the analysis, we assessed the test-retest reliability of the 8 foot up & go test by the Intraclass Correlation Coefficient (ICC 2.1) with their respective confidence intervals at 95% (95% CI). The agreement level was established by the Bland-Altman method. Results: The test-retest reliability of the 8 foot up & go test was very good (ICC: 0.98; 95% CI: 0.98- 0.99). The agreement was good in females (mean difference [MD] = 0.04 seconds and limits of agreement [LA]: -1.27; 1.36 seconds), and in elderly institutionalized (MD = 0.04 seconds [LA]: -3.18; 3.27 seconds). Conclusion: The 8 foot up & go test has very good reliability and good agreement in Colombian local elderly population.
