Assessing joint damage in juvenile idiopathic arthritis: Guide for prescribing physical exercise with the juvenile...

Juvenile idiopathic arthritis (JIA) is a chronic disease capable of causing significant structural and functional damage. The study by Kolkhidova et al demonstrated that baseline structural damage, assessed by the juvenile arthritis damage index (JADI), is a strong predictor of poor response to biological treatment. While promising, these findings require validation in larger and more diverse cohorts to enhance external applicability. In addition to reinforcing early pharmacological decision-making, these results highlight the importance of integrating a precise damage assessment into rehabilitation planning, as it can support individualized exercise prescriptions and targeted physiotherapy. JADI can identify patients with established lesions, such as contractures, who may benefit from personalized physical exercise and physiotherapy programs. A more explicit emphasis on how damage assessment guides functional planning can improve the clinical applicability of these findings. Early integration of rehabilitation alongside medication therapy can help not only restore function but also prevent further deterioration, improve adherence, and foster long-term self-management. Incorporating JADI assessment into clinical practice can optimize exercise prescription, improve mobility and strength, and ultimately enhance quality of life in patients with JIA.
