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 a Colombian local elderly population.
