What to expect from hydrotherapy for juvenile idiopathic arthritis

A paediatric physiotherapist considers the child's age, affected joints, mobility, balance, pain, energy and confidence in water. Buoyancy supports the body, allowing gentle walking, reaching, joint movement, balance games and light strengthening with less weight through painful joints. Activities are explained in child-friendly language and may use toys or goals linked to dressing, stairs, school and play.

Hydrotherapy supports rehabilitation but does not replace the child's rheumatology plan. The team may change the session when joints are more swollen or the child is tired. Families can learn more about [Hydrotherapy](/treatments/physiotherapy-and-rehabilitation/hydrotherapy/).

Tell the team about a flare, fever, rash, open skin, recent illness, medication change, unusual tiredness or difficulty getting in and out of the pool. Bring suitable swimwear, a towel, water and any mobility aid requested. Encourage the child to describe pain, temperature and tiredness rather than trying to finish every activity. Plan a calm period afterward and note changes in walking, play, sleep and joint swelling so the next session can be tailored.

Stop the session for breathing difficulty, faintness, confusion, severe pain, a fall or a child who becomes unusually drowsy or unwell. Seek prompt medical advice for a hot, very swollen joint, fever with worsening joint symptoms, new weakness or inability to bear weight. Use urgent services for serious breathing symptoms, collapse or a significant injury.

Ask how hydrotherapy fits with medicines, what to do during a flare, which joints need protection, how much activity is suitable at home, what pool support is needed, and how progress will be measured in school and play.
