Chest Expansion for Ankylosing Spondylitis
Specific rib-cage expansion exercise for ankylosing spondylitis. Counters the chest-wall stiffness that compromises vital capacity — a clinical measure of disease progression.
How to perform
- Starting position. Sit upright or stand with your hands clasped behind your head.
- Step 2. Inhale deeply through the nose, expanding the chest to its maximum (focus on pushing the ribs out to the sides).
- Step 3. Hold the maximum inhalation for 3 seconds.
- Return. Exhale slowly, then repeat without pausing between cycles.
When not to perform
- Acute rib pain
- Recent rib fracture
