What is spinal stenosis and what does it mean for how you move?
Nicola Tik
Spinal stenosis comes with a very particular set of movement experiences that can feel confusing until you understand what is behind them. This article explains what is happening in your spine, why certain activities feel harder than others, and how staying active is still very much possible.
Stenosis means narrowing. In the spine, it refers to a reduction in the space available for the spinal cord and the nerves that branch off it. This narrowing is usually the result of gradual changes over time, including thickening of the surrounding ligaments, changes to the discs, or bony growth around the joints. The nerves passing through that space can become compressed or irritated, which is what causes the symptoms most people notice.
It is a common condition, particularly from middle age onwards, and many people manage it well with an understanding of how it affects their movement.
This is where stenosis has a very recognisable pattern. When the spine moves into extension, which means standing upright or arching backwards, the available space for the nerves narrows slightly further. When the spine moves into flexion, which means leaning forward, that space opens up a little and the pressure on the nerves reduces.
This is why many people with stenosis find that leaning forward, whether over a shopping trolley, a walking frame, or simply bending slightly at the waist, brings noticeable relief. It is not coincidence. It is a direct mechanical response to the change in spinal position.
One of the most common and often puzzling experiences with spinal stenosis is a heaviness, aching, or numbness that develops in the legs during walking or standing, and then eases when you sit down or lean forward. This happens because walking and standing upright sustain the spine in an extended position, gradually increasing the pressure on the nerves. Sitting or leaning forward reverses that pressure.
This pattern is different from the kind of leg pain that comes from a disc problem, which tends to be more constant and less reliably changed by position. If your leg symptoms follow this pattern, it is your spine's response to the narrowing, not a sign of a separate problem with your legs.
Staying active is genuinely important with stenosis, and it is entirely achievable with some adjustment to how you approach movement.
Walking is still one of the most useful things you can do, even if your tolerance for it has reduced. Shorter, more frequent walks tend to work better than longer ones. Walking with a very slight forward lean, or on a slight incline such as a gentle hill, can extend how far you can go comfortably. Some people find that cycling, either outdoors or on a stationary bike, is very comfortable because the seated, slightly forward-leaning position keeps the spine in a more open position throughout.
Swimming, particularly front crawl or breaststroke with a float to avoid excessive neck extension, is another option that many people find comfortable and sustainable.
Some things to try:
If you would like a guided movement routine designed for your spine, VIDA has a short video you can follow at your own pace.
On harder days, reducing the duration of walking and standing is a sensible adjustment rather than a step backwards. It is about managing load on the nerves rather than avoiding movement altogether. Most people find that with consistent, well-paced activity their tolerance gradually improves over time.
Your VIDA pain check-in is a good way to track your walking tolerance and notice how it shifts week to week.
