What to expect from hydrotherapy for frozen shoulder

A physiotherapist checks your shoulder movement, pain, strength and ability to use the arm in daily tasks. In warm water, buoyancy can reduce the arm's effective load and make supported movement easier. You may practise reaching, turning the arm, lifting within a comfortable range, posture work and functional tasks. The therapist should distinguish a gentle stretch from a sharp or escalating pain response.

The programme is designed around [Frozen Shoulder](/conditions/frozen-shoulder/) and may change as stiffness and irritability change. Hydrotherapy does not force the joint open or guarantee a particular timeline. Your clinician can explain how it fits with home exercises and [Hydrotherapy](/treatments/physiotherapy-and-rehabilitation/hydrotherapy/).

Wear clothing that allows the shoulder to move and tell the therapist about recent injury, surgery, skin problems, fever, dizziness or difficulty using pool steps. Move slowly, breathe normally and stay within the range advised. Avoid adding extra resistance or repeating painful movements without guidance. Use the shoulder response later that day and the next morning to judge whether the dose was suitable, and keep doing only the home exercises prescribed for you.

Stop and seek advice for sudden severe shoulder pain, a visible change in shape, new loss of strength after an injury, marked swelling, fever or a hot red joint. Urgent care is needed for chest pain, severe breathlessness, fainting or new arm weakness with neurological symptoms. Tell your clinician if pain consistently worsens after treatment or daily arm use becomes more restricted.

Ask which shoulder movements are appropriate now, how much discomfort is acceptable, whether pool entry needs assistance, how to combine sessions with home exercises, and what change would prompt a different treatment approach.
