Sumario:Introduction: Functional physical performance is one of the main indicators of health and survival in the elderly. Objective: To examine the metric properties of the Alusti Test in a Peruvian geriatric hospital population Methodology: Cross-sectional methodological study in a sample of 110 older adults hospitalized in a Peruvian clinic. Together with the Alusti Test, a battery of tests was administered (Barthel Index, Gait Speed Test, Timed Up and Go Test, Short Physical Performance Battery, Mini-Mental State Examination). Statistical programs such as SPSS v. 25 for Windows, JAMOVI version 2.2.2, R, and RStudio version 4.3.1 Results: The results showed that the Alusti Test, complete and abbreviated versions, correlate with other physical performance scales, evidencing concurrent validity. Also, concurrent validity is evidenced because there is very good concordance with the Barthel index. The evidence of validity based on the internal structure of the construct corroborates the unidimensionality of the Alusti Test. Likewise, inter-observer reliability and internal consistency show high precision in the two versions of the test. Conclusions: the versions of the Alusti Test show validity and reliability to measure functional physical performance in the hospitalized geriatric population.
