| Sumario: | The World Health Organization advocates for health initiatives focused on the early detection of frailty and falls. Objectives: 1—To compare clinical characteristics, functional performance, and gait parameters (measured with the G-STRIDE inertial sensor) among different frailty groups in older adults with and without falls. 2—To identify variables that differentiate participants based on frailty status and fall history. 3—To assess the sensitivity, specificity, and accuracy of a model that classifies participants according to frailty and fall status. Methods: This observational, multicenter case-control study recruited adults over 70 years old with and without falls from two outpatient clinics and three nursing homes between September 2021 and March 2022. Clinical variables and gait parameters were collected using the G-STRIDE sensor, and Random Forest regression was used for participant stratification. Results: A total of 163 participants, with a mean age of 82.6 ± 6.2 years, of whom 118 (72%) were women, were included. Significant differences were observed in all gait parameters (both traditional and G-STRIDE evaluations). A hierarchy of factors contributed to the risk of frailty and falls. The confusion matrix and performance metrics showed high accuracy in participant classification. Conclusions: Gait parameters, especially those measured by G-STRIDE, are valuable in stratifying individuals based on frailty status and falls. These results highlight the importance of gait analysis in early intervention strategies. ChatGPT puede cometer errores. Considera verificar la información importante. ?
