Which regimen is most appropriate for maintaining joint mobility in juvenile idiopathic arthritis?

• A. Exercise in a swimming pool.
• B. Splint affected joints during activity.
• C. Passive range of motion exercises twice daily.
• D. Weight training and running.

Answer: (A)

Exercising in a swimming pool works best because water buoyancy reduces the load on joints while still allowing active movement through the full range of motion. This combination lets children with juvenile idiopathic arthritis move joints, maintain flexibility, and build muscle and endurance without the high impact or pain that can come from land-based activities. The warm, supportive environment also helps with stiffness and makes it easier to stay consistent, which is crucial for preserving mobility over time. Splinting joints during activity can protect them, but it also limits movement and isn’t ideal for maintaining ongoing mobility. Passive range of motion keeps joints moving only when someone else moves them, so it doesn’t build strength or functional capacity. Weight training and running may place excessive stress on affected joints and can provoke discomfort or flare-ups, making them less suitable for preservation of mobility in active juvenile idiopathic arthritis.
