By Mayo Clinic staffJuvenile rheumatoid arthritis (JRA) — which causes joint inflammation for at least six weeks in children 16 years old or younger — is the most common type of childhood arthritis. In most cases, symptoms of juvenile rheumatoid arthritis may fade after several months or years.
Juvenile rheumatoid arthritis can be complicated. There are several types of juvenile rheumatoid arthritis, classified based on the joints affected, symptoms and test results.
Treatment of juvenile rheumatoid arthritis focuses on preserving physical activity to maintain full joint movement and strength, preventing damage and controlling pain.
