Effectiveness of a Home-Based Multicomponent Exercise Program With Digital Support in Community-Dwelling Older Adults With Falls

The GAIT2CARE study is a multicenter, non-randomized, quasiexperimental clinical trial designed to evaluate the effectiveness of a home-based, multicomponent exercise intervention supported by a mobile application (VIVIFIL App) compared to a conventional in-person hospital-based program in community-dwelling older adults with a history of falls. The study was conducted in three public university hospitals in Spain: Hospital Universitario Infanta Leonor, Hospital Universitario de Getafe, and Hospital Universitario de Albacete. A total of 127 participants aged 70 years or older were recruited from specialized fall clinics between December 2023 and March 2024. Eligibility criteria included a history of falls, ability to walk independently or with one or two canes, and absence of terminal illness. Participants were assigned to either the intervention or control group based on their hospital site, as per standard clinical practice. The intervention group used the VIVIFIL App, a tool specifically designed for older adults to guide daily exercise at home. The App includes tailored training programs based on functional reserve (measured by SPPB), progressive difficulty levels, and real-time communication with healthcare professionals. Participants who lacked smartphones were provided with one and received training on how to use the App. The control group attended conventional multicomponent exercise sessions (45-60 minutes, 2-4 times per week) at a geriatric day hospital under professional supervision. Both programs included strength, aerobic, flexibility, and balance training. Primary outcomes included changes in physical performance (SPPB, Timed Up and Go \[TUG\], 4-meter gait speed), frailty status, and incidence of falls. Assessments were conducted at baseline and after 8 weeks. The study also included an analysis of factors influencing response to the intervention, such as baseline frailty, cognitive status, and adherence.
