Introduction: Grip strength has been established as a key indicator of general functionality in older adults and has been linked to mobility, independence, and overall health. The Short Physical Performance Battery (SPPB) is a widely used tool to assess balance, gait, and lower extremity strength in this population. This research is based on the theory of sarcopenia and active aging, where the loss of strength and physical function affects the quality of life of older adults. The present study aims to analyze the relationship between grip strength and functional capacity measured through the Short Physical Performance Battery (SPPB) in non-institutionalized older adults attending the E.S.E. Hospital San Juan de Dios in Pamplona. Materials and methods: This quantitative, descriptive, and correlational study uses dynamometry to measure grip strength and the SPPB to assess the functional capacity of the participants. A sample of fifty non-institutionalized older adults from Pamplona was selected, and the data were analyzed using Pearson's correlation coefficient to determine the relationship between both variables. Results: The average grip strength was 18 kg in the dominant hand, which was primarily the right. Good scores were found regarding the functional capacity of the older adults evaluated, specifically related to static and dynamic balance, postural control, and gait speed. There is a significant correlation between grip strength and Short Physical Performance Battery scores. Conclusion: The results obtained highlight the importance of hand strength as a predictor of functional status in older adults.
