Ankylosing spondylitis
Also known as: ankylosing spondylitis, radiographic axial spondyloarthritis, axial spondyloarthritis, inflammatory spinal arthritis, sacroiliitis
Ankylosing spondylitis is the radiographic form of axial spondyloarthritis, a chronic immune-mediated inflammatory disease that primarily affects the sacroiliac joints and spine. It commonly begins before age 45 and may cause persistent lower-back or buttock pain, morning stiffness, alternating buttock pain, night pain and improvement with movement rather than rest. Peripheral arthritis, enthesitis and dactylitis may also occur. Extra-articular manifestations include acute anterior uveitis, psoriasis and inflammatory bowel disease. Chronic inflammation may result in reduced spinal mobility, postural change, vertebral fusion, osteoporosis and an increased risk of spinal fracture. Diagnosis is based on clinical history, examination, imaging and laboratory findings rather than any single test. A normal C-reactive protein, erythrocyte sedimentation rate or negative HLA-B27 result does not exclude axial spondyloarthritis. Management commonly includes rheumatology care, education, regular exercise, specialist physiotherapy, smoking cessation and medication. Non-steroidal anti-inflammatory drugs may be used for symptoms, while biologic or targeted synthetic medicines may be considered for persistently active disease. Acupuncture may be considered as adjunctive symptom support but does not suppress the underlying immune-mediated disease or prevent structural progression. TCM patterns commonly include Cold-Damp Bi, Damp-Heat Bi, Kidney Yang deficiency, Liver-Kidney deficiency, Qi and Blood stagnation and Phlegm with Blood stasis. [1][2][3]

Lifestyle & Diet
- •Maintain regular follow-up with a rheumatologist or clinician experienced in axial spondyloarthritis.
- •Take prescribed medicines according to instructions and discuss adverse effects promptly.
- •Do not stop biologic, targeted synthetic or anti-inflammatory medicines without consulting the prescriber.
- •Participate in an individualised exercise and physiotherapy program.
- •Include spinal mobility, posture, strengthening, aerobic fitness and chest-expansion exercises.
- •Move regularly during prolonged sitting and avoid extended bed rest.
- •Choose low-impact exercise such as walking, swimming or supervised hydrotherapy when appropriate.
- •Use caution with contact sports or activities carrying a high risk of spinal trauma, particularly when fusion or osteoporosis is present.
- •Avoid high-velocity chiropractic or forceful spinal manipulation.
- •Stop smoking because smoking is associated with worse respiratory and spinal outcomes.
- •Maintain a nutritionally adequate diet and a sustainable body weight.
- •Discuss gastrointestinal protection when using non-steroidal anti-inflammatory drugs.
- •Report black stools, vomiting blood, severe abdominal pain or persistent indigestion.
- •Attend recommended blood tests and infection screening for immune-modifying medicines.
- •Discuss vaccination with the medical team before and during immunosuppressive treatment.
- •Seek same-day care for a painful red light-sensitive eye.
- •Report persistent diarrhoea, rectal bleeding, abdominal pain or unexplained weight loss.
- •Monitor psoriasis and report severe or rapidly changing skin disease.
- •Support bone health through appropriate exercise, nutrition and medical assessment.
- •Use fall-prevention strategies when spinal rigidity, poor balance or osteoporosis is present.
- •Optimise workstation, driving and sleeping ergonomics without maintaining one rigid posture for prolonged periods.
- •Seek psychological support when chronic pain, fatigue or disability affects mood or functioning.
- •Plan work modifications or occupational therapy when mobility limitations interfere with employment.
- •Do not rely on supplements, restrictive diets or complementary therapies as replacements for disease-modifying care.
Cautions & Contraindications
- •Do not treat suspected spinal fracture, cord compression, cauda equina syndrome or acute neurological loss with acupuncture or herbs.
- •Do not delay urgent ophthalmology care for suspected anterior uveitis.
- •Do not advise stopping NSAIDs, biologics, JAK inhibitors or other prescribed medicines.
- •Do not claim acupuncture or Chinese herbs cure ankylosing spondylitis, reverse fusion or reliably prevent radiographic progression.
- •Do not perform forceful spinal manipulation on a rigid, fused or osteoporotic spine.
- •Do not needle through infected skin or active psoriatic plaques.
- •Do not treat fever or suspected serious infection as a routine inflammatory flare.
- •Do not attribute bowel bleeding or persistent diarrhoea solely to Damp-Heat.
- •Avoid elective treatment during unstable cardiopulmonary illness.
- •Avoid bloodletting or strong cupping in anticoagulated, anaemic or thrombocytopenic patients.
- •Fù Zǐ must be correctly processed and professionally prescribed because of cardiotoxicity and neurotoxicity.
- •Má Huáng may be restricted and requires cardiovascular and interaction screening.
- •Xì Xīn requires botanical verification and compliance with aristolochic-acid safety standards.
- •Bàn Xià must be correctly processed because the raw herb is toxic.
- •Dāng Guī, Dān Shēn, Chuān Xiōng, Táo Rén, Hóng Huā and Niú Xī require pregnancy and bleeding-risk review.
- •Gān Cǎo may affect blood pressure, potassium and medicine metabolism.
- •Screen all herbal prescriptions for pregnancy, liver or kidney disease, infection, allergies and interactions with immunomodulatory medicines.
- •Do not interpret worsening pain, weakness, fever, visual symptoms or neurological change as a healing response.
Frequently Asked Questions
What is ankylosing spondylitis?+
It is the radiographic form of axial spondyloarthritis, an inflammatory disease that mainly affects the sacroiliac joints and spine [3].
How does inflammatory back pain differ from mechanical back pain?+
Inflammatory pain commonly begins before age 45, causes morning or night stiffness and tends to improve with movement rather than rest [3].
Does a negative HLA-B27 test exclude ankylosing spondylitis?+
No. HLA-B27 can support assessment, but a negative result does not exclude axial spondyloarthritis [3].
What other organs can be affected?+
Associated conditions include acute anterior uveitis, psoriasis and inflammatory bowel disease [3].
What is the significance of a painful red eye?+
A painful red light-sensitive eye or blurred vision may indicate acute anterior uveitis and requires same-day assessment [3].
Why are spinal injuries particularly important?+
Fusion and osteoporosis can make the spine vulnerable to unstable fractures after relatively minor trauma [3].
What treatments are commonly used?+
Management may include education, specialist exercise and physiotherapy, NSAIDs and biologic or targeted synthetic medicines for active disease [3].
Which TCM patterns may be considered?+
Patterns may include Cold-Damp Bi, Damp-Heat Bi, Kidney Yang deficiency, Liver-Kidney deficiency, Qi-Blood stagnation and Phlegm with Blood stasis [4].
Can acupuncture cure ankylosing spondylitis?+
No. Acupuncture may support pain management but has not been established as a cure or a replacement for disease-modifying treatment [4].
Is spinal manipulation safe?+
Forceful or high-velocity manipulation may be dangerous in a fused or osteoporotic spine and should be avoided [3].
