What Is Spinal Stenosis?
Spinal stenosis is a narrowing of the spinal canal or the spaces through which nerve roots pass. In the lumbar spine (lower back), this narrowing places pressure on the nerves, causing pain, numbness, tingling and weakness in the legs — often described as neurogenic claudication.
Classic symptoms include:
- Back and leg pain that worsens with walking and standing
- Relief when sitting down or leaning forward (such as pushing a shopping trolley)
- Numbness, tingling or weakness in one or both legs
- Reduced walking distance over time
- Difficulty with prolonged standing
How Does Physiotherapy Help Spinal Stenosis?
Physiotherapy cannot widen the spinal canal — but it can significantly improve how you cope with the narrowing by:
Improving Spinal Flexion
Spinal flexion (forward bending) opens the spinal canal and reduces nerve compression. Physiotherapy identifies flexion-biased exercises and positions that provide symptom relief and improve walking capacity.
Strengthening Core and Hip Muscles
Stronger core and hip muscles reduce the mechanical demand on the lumbar spine, improving stability and reducing compressive forces on the narrowed canal.
Improving Walking Tolerance
A structured walking programme with specific pacing strategies, posture cues and rest positions can progressively increase walking distance despite stenosis.
Manual Therapy
Soft tissue techniques and gentle joint mobilisation help reduce muscle guarding and improve mobility around the affected spinal segments.
The "Shopping Trolley Sign" and What It Tells Us
Many people with spinal stenosis find that leaning forward — such as when pushing a shopping trolley or leaning on a stick — relieves their leg symptoms. This is because flexion slightly opens the narrowed canal. Understanding this principle allows physiotherapists to prescribe specific postures and exercises that mimic this effect therapeutically.
When Is Surgery Needed?
Surgery is considered for spinal stenosis when conservative management (including physiotherapy) has failed to provide adequate symptom relief, when symptoms are progressively worsening, or when significant neurological deficits are present. For most patients, physiotherapy represents the most effective and safest first-line approach.
