Hidden muscle loss in young arthritis patients under the microscope
NCT ID NCT07634354
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how often muscle weakness and loss (sarcopenia) happens in people aged 15 to 40 with juvenile idiopathic arthritis. Researchers will measure grip strength, do body scans, and use questionnaires to check muscle health. The goal is to find out how common this problem is and what factors might be linked to it, so doctors can help patients earlier.
