Stenosis is a word that a lot of people have heard of and might even relate it to some sort of spinal condition, but it is not often well understood. In short, the word stenosis means “narrowing.” In the lumbar spine, it implies the narrowing of a canal where either the spinal cord itself runs or where the spinal nerve exits the spine to travel down into the leg. The canals that these neural structures run through can become narrowed either by overgrowth of the bone that makes up the canal or by a nearby bulging disc. It is not the stenosis itself that causes symptoms, but the pressure that the narrowed canal puts on the nerves. That pressure can cause pain, numbness, tingling, or weakness in the back and legs, or disturbed bowel or bladder function. Symptoms often worsen with prolonged standing or walking and may improve when sitting or bending forward. It occurs most often in people over the age of 50 and can have a significant impact on the quality of life.
In my practice stenosis is a particularly concerning finding, because it often discourages people from being active since they can’t walk or be on their feet for any significant length of time. It engenders inactivity, which further perpetuates poor health and physical fitness, which in turn lead to more back problems. The beauty of this study is that it gives hope to those who suffer from lumbar spinal stenosis. What I like about it is that it advocates a multimodal approach, attacking the problem from multiple directions to produce a long term, effective solution. It is similar to the way we approach each of our patients’ concerns – through education , simple, progressive home care stretches and exercises, and effective chiropractic adjustments and manual therapies. We believe that the best results are achieved when both the healthcare provider and the patient take appropriate action to treat pain and prevent further injury and disability and this study is a fantastic example of this approach.
