Phone nudges get seniors out of bed – study tests if tech can boost activity

This study tested whether a mobile app that gives visual feedback and motivational reminders can help older adults (60+) with conditions like COPD, heart failure, or Parkinson's spend more time out of bed while in the hospital and for three months after going home. Researchers tracked activity with a small accelerometer and measured time spent lying, sitting, standing, and walking. The goal was to see if simple tech nudges can encourage more movement and reduce hospital readmissions.
