Due to the impact of COVID-19, telehealth technologies have become crucial for managing the health of community-dwelling older adults with frailty.

This research aimed to investigate the effectiveness of this intervention on physical activity and kinanthropometric measures. This quasi-experimental research involved 81 older adults from community care centers, with 43 in the experimental group receiving the FANS and 38 in the control group continuing their usual health activities. Outcome measures, evaluated using intention-to-treat analysis, included physical activity (assessed with the Short Physical Performance Battery, grip strength, Timed Up and Go test, and overall activity level) and kinanthropometric measures (body mass index, mid-upper arm circumference, and calf circumference). Changes over 3 and 6 months were analyzed using Generalized Estimating Equations. The intervention group exhibited significant improvements in all physical activity measures (p
