Smartphone Imaging for Remote Monitoring of Inflammatory Arthritis in a Real-World Cohort: Longitudinal Evaluation of a Machine Learning-Based Finger Fold Biomarker

2026-07-31

Abstract excerpt

<h4>Background</h4> Smartphone enabled remote patient monitoring has the potential to complement conventional follow-up in inflammatory arthritis. We previously presented the finger fold index (FFI) derived from hand photographs as ratio of automated detected proximal interphalangeal (PIP) joint diameter and surface of dorsal finger folds as a digital biomarker for clinical joint swelling and disease activity in...
