Summary

This study tested whether a mobile app with sensors could help 174 adults with chronic kneecap pain follow their home exercise program. Participants received 1, 3, or 6 face-to-face remote training sessions and then exercised on their own for 6 weeks. The app tracked how much they exercised, and researchers also measured pain, strength, and knee function. The goal was to see if more coaching sessions improved adherence and outcomes.
