Ankylosing spondylitis

A rheumatic disease that usually starts before the age of 40 and causes inflammatory pain and stiffness in the lower and upper back. Its most typical feature is pain that gets worse with rest and better with movement. Alongside medication, regular exercise is an essential part of treatment.

What is it?

Ankylosing spondylitis is an inflammatory rheumatic disease that affects the spine and the sacroiliac joints, where the spine joins the pelvis. Today it is considered part of a broader group called axial spondyloarthritis. If the inflammation is not brought under control for a long time, new bone can form in the spine and movement can become permanently restricted.

Because the symptoms come on gradually and are mistaken for ordinary back pain, diagnosis is often delayed for years. Early diagnosis and treatment are important for keeping you mobile.

How do you recognise inflammatory back pain?

  • Back pain that starts gradually before the age of 40 and lasts longer than 3 months
  • Pain that does not go away with rest but eases with movement
  • Pain that wakes you at night, especially in the early hours of the morning, and eases once you get up and move
  • Morning stiffness lasting longer than half an hour
  • Buttock pain that alternates from one side to the other
  • Pain in the heel, the Achilles tendon or the chest wall; redness and pain in the eye

Treatment: medication and exercise together

According to the recommendations of the Assessment of SpondyloArthritis international Society (ASAS) and EULAR, updated in 2022, the cornerstones of treatment are information about the condition, regular exercise, stopping smoking and, when needed, physiotherapy. The first step in medication is anti-inflammatory painkillers (NSAIDs). If the disease stays active, a rheumatologist plans advanced treatments such as biologic medicines or JAK inhibitors. Long-term cortisone treatment is not recommended when the spine is affected.

In a 2019 Cochrane review covering 14 studies and 1,579 patients, exercise programmes lasting 12 weeks on average, mostly added to medication, slightly improved day-to-day function and slightly reduced disease activity as rated by patients, compared with no exercise. Pain could also ease: pain scored at 6.2 out of 10 was about 2 points lower in those who exercised. In people already receiving physiotherapy or regular treatment, exercise gave a smaller additional benefit.

Smoking is linked to more active disease and faster new bone formation in the spine; stopping smoking is part of treatment.

  • Regular exerciseFlexibility, posture, strengthening and aerobic exercise. Exercising in water is also a good option.
  • PhysiotherapySupervised, individually tailored programmes are especially helpful if movement has already started to become restricted.
  • Posture and breathingTaking care to stand up straight during the day and doing deep breathing exercises help keep your rib cage flexible.
  • MedicationAnti-inflammatory painkillers (NSAIDs) and, when needed, advanced treatments planned by a rheumatologist.
  • Eye and associated problemsSeeking help quickly for symptoms such as redness and pain in the eye prevents permanent damage.

Exercises at home

Six exercises for posture and flexibility

The programmes in the studies mostly consisted of strengthening, flexibility, stretching and breathing exercises. Do these exercises every day, ideally after a warm shower to ease morning stiffness. Move through your full range, slowly and without holding your breath.

Wall posture stretch

Wall posture stretch

Stand with your back against a wall, with your heels, buttocks and shoulder blades touching it. Gently tuck your chin in and bring the back of your head towards the wall; hold for 5 seconds. Checking from time to time how close your head gets to the wall helps you keep track of your posture.

10 reps, every day
Chin tuck

Chin tuck

Sit or stand up straight, looking straight ahead. Without tilting your head, draw your chin straight back and feel the back of your neck lengthen. Hold for 5 seconds, then release.

10 reps, twice a day
Upper back (thoracic) extension

Upper back (thoracic) extension

Sit on a chair with a low back and clasp your hands behind your neck. Lifting your chest towards the ceiling, gently arch your upper back backwards over the top edge of the chair. Take a deep breath as you do this.

10 reps, every day
Cat–camel

Cat–camel

Get on your hands and knees. As you breathe out, round your back up towards the ceiling; as you breathe in, let your lower back sink and lift your head. Move slowly, using your whole spine.

10 reps, every day
Prone press-up on elbows

Prone press-up on elbows

Lie on your front. Bring your elbows under your shoulders and slowly lift your chest off the floor, keeping your hips on the floor. Hold for a few seconds, then slowly lower yourself down. It is a good exercise to counter a stooped posture.

10 reps, every day
Bird dog

Bird dog

Get on your hands and knees with your back flat. Reach one arm forwards and the opposite leg backwards, without letting your lower back sag. Hold for 5 seconds, then switch sides.

8–10 reps on each side

Frequently asked questions

Is ankylosing spondylitis hereditary?

Genetic predisposition is important: most patients carry a tissue type called HLA-B27. However, most people who carry HLA-B27 never develop the disease, and this test alone cannot confirm the diagnosis.

Won't exercise make my pain worse?

Inflammatory back pain eases with movement and gets worse with rest. Regular exercise reduces stiffness and helps maintain your range of movement and your posture. During painful flare-ups, reduce the intensity, but keep moving.

Which sports can I do?

Swimming, exercising in water, walking, cycling, Pilates and yoga are all suitable options. People whose spine has become severely stiff should avoid sports with a risk of falls and knocks, because a stiffened spine can fracture even after a minor knock.

I'm taking medication. Should I still exercise?

Yes. Medication controls the inflammation, while exercise keeps you mobile and maintains your posture and muscle strength. Guidelines recommend using both together.

When to seek help right away

See a doctor without delay if you have any of the following:

  • Redness, pain, sensitivity to light or blurred vision in the eye (see an eye doctor the same day)
  • New, severe back or neck pain after a minor fall or knock
  • Numbness or weakness in the arms or legs; problems controlling your bladder or bowels
  • Fever or unexplained weight loss
  • Chest pain and shortness of breath (call 112)
