Ankylosing spondylitis (AS) is a type of chronic inflammatory arthritis that primarily affects the spine, though it can involve other joints as well. Because its early symptoms are often mistaken for ordinary back pain, many people live with the condition for years before receiving an accurate diagnosis. Understanding the signs — and knowing that physiotherapy plays a central role in managing it — can make a meaningful difference in quality of life.
What Is Ankylosing Spondylitis?
Ankylosing spondylitis is an autoimmune condition in which the immune system causes inflammation in the joints of the spine and the sacroiliac joints (where the spine connects to the pelvis). Over time, if left unmanaged, this inflammation can lead to new bone formation between vertebrae, gradually reducing spinal flexibility.
The exact cause isn’t fully understood, but genetics play a significant role — the condition is strongly associated with a gene called HLA-B27, and it often runs in families.
Common Symptoms of Ankylosing Spondylitis
- Lower back and hip pain that develops gradually, usually before age 40
- Stiffness that is worse in the morning or after periods of inactivity, and improves with movement and exercise
- Pain that wakes you up in the second half of the night
- Fatigue
- In some cases, pain and swelling in other joints, such as the hips, shoulders, or heels
- Reduced flexibility in the spine over time
The key distinguishing feature is that AS-related back pain typically improves with activity and worsens with rest — the opposite of most mechanical back pain, which tends to worsen with movement.
Getting an Accurate Diagnosis
Because early symptoms can resemble ordinary back strain, ankylosing spondylitis is frequently diagnosed later than it should be. If your back pain has lasted more than three months, started before age 40, and improves with exercise rather than rest, it’s worth discussing with a rheumatologist, who can confirm a diagnosis through clinical assessment, blood tests, and imaging.
How Physiotherapy Helps Manage Ankylosing Spondylitis
While there’s no cure for AS, physiotherapy is one of the most effective tools for managing symptoms and preserving mobility over the long term. A structured, supervised exercise program can make a real difference in how the condition progresses.
- Postural exercises. Because AS can gradually affect spinal alignment, exercises that maintain an upright posture help prevent the stooped position that can develop in advanced cases.
- Mobility and stretching exercises. Regular movement helps maintain flexibility in the spine and surrounding joints, counteracting stiffness.
- Breathing exercises. In some cases, AS can affect the joints connecting the ribs to the spine, which can restrict chest expansion. Specific breathing exercises help maintain lung capacity.
- Strength training. Building strength in the muscles supporting the spine helps offload pressure from the joints and improves overall function.
- Hydrotherapy. Exercising in water reduces load on the joints while still providing resistance, making it an excellent option for many people with AS, especially during flare-ups.
Staying Active Is Key
One of the most important things to understand about ankylosing spondylitis is that movement is medicine. Unlike many other conditions where rest is recommended, AS responds best to consistent, appropriate activity. A physiotherapist can help you build a program that’s safe, effective, and adapted to how your symptoms change over time — including during flare-ups, when exercises may need to be modified rather than stopped altogether.
Living Well with Ankylosing Spondylitis
Beyond structured exercise sessions, small daily habits make a real difference: staying active throughout the day rather than sitting for long stretches, sleeping on a supportive mattress that encourages good spinal alignment, and practicing posture awareness during work or study. Many patients also find that swimming and cycling are excellent low-impact activities to maintain between physiotherapy sessions.
Frequently Asked Questions
Is ankylosing spondylitis curable?
There is currently no cure for ankylosing spondylitis, but with appropriate management — including physiotherapy, and in some cases medication prescribed by a rheumatologist — most people maintain good function and quality of life for many years.
Can ankylosing spondylitis be managed with physiotherapy alone?
Physiotherapy is a cornerstone of managing AS and is highly effective at preserving mobility and reducing symptoms. Depending on disease activity, your rheumatologist may also recommend medication alongside physiotherapy for optimal results.
How is ankylosing spondylitis different from ordinary back pain?
The clearest difference is the pattern: AS-related pain typically improves with movement and worsens with rest, often with prominent morning stiffness lasting more than 30 minutes — while typical mechanical back pain tends to worsen with activity.
At what age does ankylosing spondylitis usually start?
Symptoms most commonly begin between the late teens and age 40, though the condition is sometimes not diagnosed until years after symptoms first appear.
