Lumbar spinal stenosis: when walking becomes a challenge
Pain, numbness or weakness in the legs when walking that improves with rest or sitting.
Lumbar spinal stenosis has a distinctive pattern - walking for just a few minutes brings on pain or numbness in the legs, but a short sit allows you to carry on again.
Some people can walk only a few minutes before pain, heaviness or numbness appears in the legs, but after sitting briefly they can carry on again. This kind of pattern is sometimes characteristic of lumbar spinal stenosis. I hear quite a few patients describe it as “stopping every few minutes at a shop window” to give the legs a rest - and they don’t always connect it to the back, even though that is exactly the source.
What is spinal stenosis?
The spinal canal is the passage through which the spinal cord and nerve roots run. Over the years, changes can appear that reduce the space available to the nerves and may cause symptoms during standing and walking - when the back leans backward (as in upright standing) the canal narrows further, and that is exactly what explains why bending forward or sitting brings relief.
Walking with a slight forward lean, or while pushing a shopping trolley, brings relief to many people with stenosis - that is no coincidence, and it is also a diagnostic clue worth sharing with me.
How does it usually feel?
- Pain in the lower back.
- Pain or numbness in the legs.
- Worsening when walking or standing.
- Relief when sitting or bending forward.
- A reduction in walking distance.
- Progressive weakness in the legs
- A change in bladder or bowel control
- Numbness in the saddle area (inner thighs and buttocks)
- A significant, sudden reduction in walking distance
How can physiotherapy help?
After assessment, we build a rehab plan: exercises to improve movement, muscle strengthening (mainly the core and abdominal muscles, which support a more comfortable spine position), building endurance, and guidance on managing loads to fit your capacity.
Frequently asked questions
No. Many people manage to improve function with conservative treatment, and sometimes significantly increase their walking distance without needing surgical intervention.
In some people, sitting or bending forward reduces the load on the structures in the area and slightly widens the canal - that is the physiological explanation for a pattern so common in this condition.
When the pain or numbness limits walking or worsens over time.
What’s worth remembering?
Even when spinal stenosis has been diagnosed, in many cases function and quality of life can be improved with an appropriate rehabilitation plan.
- When the back leans backward, as in upright standing, the canal narrows further - which explains why bending forward or sitting brings relief.
- Walking with a slight forward lean, or while pushing a shopping trolley, brings relief to many people with stenosis.
- A progressive reduction in walking distance or weakness in the legs requires prompt assessment.
