App and wearable track daily pain and fatigue in arthritis patients

This study tested whether a smartphone app and a wearable activity tracker are practical and acceptable for people with inflammatory rheumatic diseases like rheumatoid arthritis and spondyloarthritis. Over 14 days, 50 participants answered short surveys on their phone and wore a device to track movement. The goal was to see how fatigue, pain, mood, and sleep affect physical activity in real time. No treatment was given; the study focused on refining methods for future research.
