Physical Therapy vs Surgical Decompression for Lumbar Spinal Stenosis

This is a randomized controlled multicenter trail comparing physical therapy to surgical decompression in patients with lumbar spinal stenosis. The 0-hypothesis is that there is no difference in the efficacy of structured physical therapy compared to surgical decompression. Our aim is to evaluate if physical therapy can serve as a nonsurgical alternative for patients with LSS, where the severity of symptoms indicates the need of surgical decompression.
