How common is reduced range of motion in ankylosing spondylitis?

Movement may feel restricted after rest and become easier after gentle activity, although a flare can make stiffness more persistent. The spine may lose flexibility gradually, while hip or shoulder involvement can affect dressing, walking, turning, or reaching. Reduced chest expansion may also make deep breaths feel limited. The symptom varies between people and does not by itself confirm the diagnosis; assessment considers the pattern of stiffness, pain, examination findings, and other features.

Keep a record of when stiffness appears, which movements are difficult, and whether activity changes it. Regular clinician-guided mobility exercises, posture work, and breathing exercises can help preserve function. A physiotherapist can adapt movements for your spine and joints, while your treating clinician can review inflammation control and medicines. Avoid forcing a painful joint or staying in one position for long periods.

Arrange an assessment if restricted movement is new, worsening, or interfering with sleep, work, walking, or self-care. Seek urgent help for sudden severe pain after an injury, new weakness or numbness, loss of bladder or bowel control, fever with a hot swollen joint, or difficulty breathing. These features need prompt evaluation rather than waiting for routine exercises to help.

Which joints or parts of my spine appear restricted? Could inflammation explain the pattern? Which movements are appropriate during a flare? Would physiotherapy or breathing exercises suit me? How will we monitor changes in flexibility and function?
