Lumbar spinal stenosis — narrowing of the spinal canal that compresses the nerves supplying the legs — is one of the most common causes of leg pain and reduced walking capacity in people over 60. Physiotherapy significantly improves walking tolerance and quality of life for most patients, often avoiding or deferring the need for surgery.
The Classic Stenosis Presentation
The hallmark of lumbar spinal stenosis is neurogenic claudication — a predictable pattern of leg heaviness, cramping, weakness, or pain that develops after walking a certain distance. Critically, it is relieved by sitting or forward flexion (leaning on a shopping trolley, crouching). This distinguishes it from vascular claudication (arterial disease), which is relieved by simply stopping and standing still.
Patients often report being able to walk uphill or on a treadmill (with slight forward lean) better than walking on a flat surface, because the forward flexion opens the canal.
Physiotherapy Management
Flexion-based exercise program: Exercises that use lumbar flexion (knee-to-chest, posterior pelvic tilt, lumbar flexion stretches) to temporarily open the canal and provide symptom relief. Cycling — an inherently flexed lumbar posture — is an excellent activity for maintaining aerobic fitness.
Core stabilisation: Building deep core stability reduces the dynamic narrowing of the spinal canal that occurs with lumbar extension during walking. Transversus abdominis and multifidus activation exercises are central to management.
Gait modification: Teaching patients to walk with a slightly flexed forward trunk (simulating the shopping trolley position), use of a walking stick or rollator if needed to allow forward lean.
Manual therapy: Lumbar joint mobilisation and soft tissue techniques for symptom management and improving mobility.
Pain education: Understanding the mechanism of neurogenic claudication reduces fear and allows more confident engagement with activity.

Frequently Asked Questions
What is lumbar spinal stenosis?
Lumbar spinal stenosis is a narrowing of the spinal canal (central stenosis) or the openings through which nerve roots exit (foraminal stenosis) in the lumbar spine. Narrowing is most commonly caused by disc bulging combined with facet joint hypertrophy (enlargement) and ligamentum flavum thickening — changes that accumulate with age. The nerves supplying the legs become compressed, producing the characteristic leg symptoms with walking.
Why does forward bending help spinal stenosis?
Flexing the lumbar spine (forward bending) opens the spinal canal and neural foraminae, reducing pressure on the neural structures. This explains why people with stenosis prefer sitting, riding bikes, or pushing a shopping trolley (leaning forward) over walking upright. Lying face up with knees bent also opens the canal. Exercises for stenosis exploit this pattern.
How is spinal stenosis diagnosed?
Clinical diagnosis is based on the history (neurogenic claudication pattern) and physical examination. MRI is the imaging of choice to confirm the level and severity of stenosis. An X-ray may show degenerative changes but does not show the neural compression directly. A physiotherapist will assess the clinical presentation, then refer for imaging if not already performed.
Is surgery always necessary for spinal stenosis?
No. Many people with confirmed lumbar spinal stenosis manage well with conservative physiotherapy for years. Surgery (laminectomy or laminotomy to decompress the neural elements) is considered when: walking tolerance is severely limited (less than 100 metres), quality of life is significantly impacted despite optimised conservative management, or significant neurological deficit (weakness) is present. Conservative management often stabilises or improves symptoms without surgery.
