The objective assessment of physical activity levels through wearable inertial-based motion
detectors for the automatic, continuous and long-term monitoring of people in free-living …

Abstract Objectives Digital health interventions (DHIs) are interesting resources to improve
various health conditions. However, their use in the older and frail population is still sparse …

Background A growing interest in frailty syndrome exists because it is regarded as a major
predictor of co-morbidities and mortality in older populations. Nevertheless, frailty …

Clinicians commonly use questionnaires and tests based on daily life activities to evaluate
physical function. However, the outcomes are usually more qualitative than quantitative and …

This work analyses different concepts for frailty diagnosis based on affordable standard
technology such as smartphones or wearable devices. The goal is to provide ideas that go …

The ability to stand up from a sitting position is essential for older adults to live
independently. Body-fixed inertial sensors may provide an approach for quantifying the sit-to …

Background Sit-to-stand and stand-to-sit transitions are frequent daily functional tasks
indicative of muscle power and balance performance. Monitoring these postural transitions …

Objectives To evaluate the effects of an exercise intervention on physical function, maximal
muscle strength, and muscle power in very old hospitalized patients. Design In a …

The latest studies of the 30-second sit-to-stand (30-STS) test aim to describe it by employing
kinematic variables, muscular activity, or fatigue through electromyography (EMG) instead of …

Background Frailty assessment is a critical approach in assessing the health status of older
people. The clinical tools deployed by geriatricians to assess frailty can be grouped into two …
