Frailty syndrome is an independent risk factor for serious health episodes, disability,
hospitalization, falls, loss of mobility, and cardiovascular disease. Its high reversibility demands
personalized interventions among which exercise programs are highly efficient to contribute to its
delay. Information technology-based solutions to support frailty have been recently approached, but
most of them are focused on assessment and not on intervention. This paper describes a sensor-based
mHealth platform integrated in a service-based architecture inside the FRAIL project towards the
remote monitoring and intervention of pre-frail and frail patients at home. The aim of this platform is
constituting an efficient and scalable system for reducing both the impact of aging and the advance of
frailty syndrome. Among the results of this work are: (1) the development of elderly-focused sensors
and platform; (2) a technical validation process of the sensor devices and the mHealth platform
with young adults; and (3) an assessment of usability and acceptability of the devices with a set of
pre-frail and frail patients. After the promising results obtained, future steps of this work involve
performing a clinical validation in order to quantify the impact of the platform on health outcomes of
frail patients.Consejería de Conocimiento, Investigación y Universidad P18-TPJ-307
