Why does frozen shoulder cause shoulder stiffness?

The shoulder capsule normally expands and folds as the arm changes position. Frozen shoulder changes that tissue, so it has less room to stretch and the joint surfaces cannot glide as freely. Reaching overhead, behind your back or across your body may become difficult, sometimes in a recognisable pattern.

Shoulder Stiffness is a very common presentation of Frozen Shoulder. Pain can make you hold the arm close to the body, but the contracted capsule itself is also a physical restriction. Stiffness may therefore remain even when pain temporarily settles.

An examination can measure active and passive movement and help distinguish frozen shoulder from problems affecting the rotator cuff or neck. A physiotherapist may prescribe controlled movements that match the current phase. Short, regular practice is often easier to tolerate than forceful sessions.

Keep the shoulder gently active for daily tasks when comfortable, but do not repeatedly force the arm into severe pain. Discuss pain relief, heat or other options with a clinician who knows your conditions and medicines.

Book an assessment when stiffness is progressing, persists after an injury, or interferes with washing, dressing or work. Get urgent help for sudden weakness, a visibly deformed shoulder, severe swelling, fever, a cold or blue hand, or shoulder symptoms with chest pain or breathing difficulty.

Which movements are restricted on examination? What level of stretching is appropriate now? Could diabetes, thyroid disease or a previous shoulder injury affect my care? When should the exercise plan be reviewed if motion is not improving?
