AI-powered fitness wearables and apps to boost activity in older adults living alone with cognitive decline

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study will evaluate an AI-driven fitness app, a social support feature within the app, and a health education component to see if they can increase physical activity and improve health outcomes in community-dwelling older adults aged 65 and older who live alone and have mild cognitive decline. Over six months, participants will use wearable devices and mobile apps that provide real-time feedback, goal setting, and social connectivity to promote activity and reduce sedentary behavior. The study will explore which components most effectively influence behavioral mechanisms such as self-efficacy and outcome expectations, and how these mediate changes in activity levels. The trial aims to identify optimal component combinations for future efficacy testing and to illuminate the mechanisms of behavioral change driven by mHealth interventions in this population.
