How long does hydrotherapy take to work for frozen shoulder?

Warm water supports the arm and may let you practise reaching, rotation, and gentle stretching with less guarding. A session may temporarily improve comfort or movement, while lasting change depends on the stiffness phase, irritability, and regular practice.

Frozen shoulder often changes gradually. Progress can mean reaching a little higher, fastening clothing more easily, or sleeping with less disturbance. Pain may settle at a different pace from movement, so both should be recorded.

Follow the therapist’s range and effort guidance rather than forcing a painful stretch. Use the recommended home movements between pool sessions, keeping them smooth and controlled. Mention night pain, pain after exercise, or a feeling that the shoulder is becoming more restricted.

Arrive prepared to describe what tasks are difficult. Your clinician may alter the water exercises, add land-based work, or discuss another option if progress has plateaued.

Arrange a review if pain or stiffness keeps worsening, new weakness prevents lifting the arm, or treatment repeatedly causes a flare that lasts into the following day. Seek urgent help after a significant injury, or for a hot swollen joint with fever or sudden severe pain.

Ask what shoulder movements are realistic targets, how progress will be measured, and when the programme should be reassessed. Clarify which sensations are expected during stretching and which mean you should stop.
