When is hydrotherapy recommended for ankylosing spondylitis?

Warm water can make gentle spinal, hip and shoulder movements more comfortable, while buoyancy reduces the load on painful areas. A physiotherapist can adjust the depth, pace and exercises to your mobility, fatigue and flare pattern. Hydrotherapy supports flexibility, posture and general conditioning; it complements, rather than replaces, medical treatment and an individual home programme.

Tell the physiotherapist whether morning stiffness, fatigue, pain or balance problems limit you. Wear suitable pool footwear, take breaks before exhaustion, and use the pool rail or assistance if balance is uncertain. Follow the prescribed intensity rather than forcing a stiff spine through pain. Ask how to continue gentle mobility work between sessions and how to adjust activity during a flare.

Contact your care team if exercise produces a sustained worsening of pain, unusual weakness or a new change in walking. Seek urgent care for sudden loss of strength or sensation, new bladder or bowel difficulty, chest pain, severe breathlessness or a serious fall. Fever or an acutely swollen joint also needs medical assessment.

Ask whether your current symptoms and spinal mobility make pool therapy appropriate, what exercises should be included, how often to attend, and what to do if symptoms flare. Check whether skin, heart, breathing or continence issues require special pool precautions.
