Nonsurgical treatment of lumbar spinal stenosis

I treat many patients with lumbar spinal stenosis and it many time leads to leg pain and weakness with standing and walking. a new study in the medical journal Archives of Physical Medicines showed that a comprehensive conservative program demonstrated superior, large, and sustained improvements in walking ability and can be a safe nonsurgical treatment option for patients with sciatica due to lumbar spinal stenosis.
Has anyone had treatment for this condition?
