Lumbar spinal stenosis (LSS) is a degenerative condition of the spine, affecting 30% of older adults. LSS can cause significant functional limitation related to walking, disability, and increased risk of falling. This condition is often treated surgically, with the rate of complex spinal fusions in the United States increasing by 137% between 1998 and 2008. These types of surgeries are costly, and come with risks, complications, and rehospitalizations.
