🦴 Ankylosing Spondylitis: A Deeper Look at the Condition

Ankylosing spondylitis (AS) is a chronic, systemic inflammatory disease that primarily affects the axial skeleton, meaning the spine, sacroiliac (SI) joints, ribs, and pelvis. Unlike mechanical back pain, AS is driven by immune system–mediated inflammation, not overuse or injury.

Over time, persistent inflammation can lead to structural changes in joints and connective tissue, including abnormal bone growth and joint fusion.

🔥 What Causes Ankylosing Spondylitis?

AS is classified as a seronegative spondyloarthropathy, meaning:

• It is autoimmune or immune-mediated

• It does not show typical rheumatoid factor in blood tests

• It primarily affects the spine and entheses (where tendons and ligaments attach to bone)

🧬 Genetic Factors

• Up to 90% of people with AS carry the HLA-B27 gene

• Having the gene does not guarantee AS, but it increases susceptibility

• Environmental and immune triggers likely activate the disease process

🧠 The Role of Inflammation in AS

Inflammation in AS is enthesitis-driven, meaning it targets the entheses — the attachment points of:

• Ligaments

• Tendons

• Fascia

• Joint capsules

These structures are richly innervated and sensitive to inflammatory signaling, which helps explain why AS pain is often deep, aching, and persistent.

Chronic inflammation can lead to:

• Tissue thickening

• Fibrosis

• Calcification

• New bone formation

This process is what can eventually cause spinal rigidity or fusion (ankylosis).

⏰ How AS Pain Differs from Mechanical Back Pain

One of the hallmarks of ankylosing spondylitis is its distinct pain pattern:

AS Pain Characteristics	Mechanical Pain
Worse at rest	Worse with activity
Improves with movement	Improves with rest
Morning stiffness >30–60 min	Short-lived stiffness
Night pain (especially early morning)	Rare night pain
Chronic, progressive	Often episodic

This is why many people with AS are initially misdiagnosed with “tight muscles” or “postural pain.”

🦴 Areas Commonly Affected by Ankylosing Spondylitis

AS is not limited to the spine. It may affect:

🔹 Axial Skeleton

• Sacroiliac joints (often the first site)

• Lumbar and thoracic spine

• Cervical spine

• Rib joints (affecting breathing)

🔹 Peripheral Joints

• Hips (commonly)

• Shoulders

• Knees and ankles (less common)

🔹 Soft Tissues

• Fascia

• Tendons

• Ligaments

• Joint capsules

🌬️ Effects on Breathing and Posture

When inflammation affects the costovertebral and costosternal joints, rib movement may become restricted. This can lead to:

• Shallow breathing patterns

• Reduced chest expansion

• Increased accessory muscle use

• Heightened nervous system stress

Postural adaptations may include:

• Forward head posture

• Thoracic kyphosis

• Reduced spinal extension

🧠 Fatigue, Pain Processing & the Nervous System

Chronic inflammation doesn’t only affect joints — it also impacts the central nervous system.

People with AS often experience:

• Chronic fatigue

• Poor sleep quality

• Heightened pain sensitivity

• Nervous system dysregulation

• Increased stress and anxiety

This is why nervous system–informed therapies can be especially valuable.

🧪 Diagnosis: Why AS Is Often Missed

AS can be challenging to diagnose because:

• Early imaging may appear normal

• Symptoms overlap with mechanical back pain

• Inflammatory markers may fluctuate

• Symptoms often begin in young adulthood

Diagnosis may include:

• MRI of SI joints

• X-rays (later stages)

• HLA-B27 testing

• Clinical history and symptom pattern

🌿 Why Supportive Therapies Matter

Because AS affects joints, fascia, muscles, nerves, breathing mechanics, and stress physiology, care should be multidimensional.

Supportive therapies aim to:

• Reduce secondary muscle tension

• Improve circulation and tissue mobility

• Support posture and breathing

• Calm the nervous system

• Improve quality of life

These approaches work alongside medical management — not in place of it.

💆‍♀️ How Massage Therapy May Help Ankylosing Spondylitis

Massage therapy does not treat the underlying autoimmune process, but it may help manage secondary symptoms associated with AS:

✔️ Reduces muscle guarding around inflamed joints

✔️ Improves circulation to stiff tissues

✔️ Supports posture and mobility

✔️ Helps calm the nervous system

✔️ May decrease stress-related pain amplification

Gentle, therapeutic approaches — rather than deep or aggressive work — are often best during inflammatory flare-ups.

⚡ How Microcurrent Therapy May Support Healing

Microcurrent therapy uses low-level electrical currents that mimic the body’s natural bioelectric signals. For individuals with ankylosing spondylitis, microcurrent may help by:

✔️ Supporting cellular repair processes

✔️ Reducing pain signaling

✔️ Calming nervous system hyperactivity

✔️ Supporting tissue recovery between flare-ups

✔️ Assisting with chronic inflammation management

Microcurrent is typically non-invasive, gentle, and well-tolerated — making it a valuable option for clients with chronic inflammatory conditions.

🌿 A Whole-Body, Nervous-System–Informed Approach

Ankylosing spondylitis affects more than just the spine. Pain, inflammation, stress, and fatigue are deeply interconnected. Combining medical care with supportive therapies like massage and microcurrent can help individuals feel more comfortable, mobile, and regulated in their bodies.

✨ The goal isn’t to “fix” AS — it’s to improve quality of life, comfort, and function.

💬 Key Takeaway

Ankylosing spondylitis is not just back pain. It is a whole-body inflammatory condition that affects movement, breathing, posture, energy, and nervous system regulation. Understanding the underlying mechanisms helps both practitioners and clients choose gentle, informed, and sustainable care strategies.
