Multicenter Randomized Controlled Trial of Epidural Steroid Injections for Spinal Stenosis in Persons 50 and Older (LESS)
Rochester, Minn.
The broad, long-term objective of this research protocol is to improve the quality of life for patients suffering from lumbar spinal stenosis. This objective will be met by examining the safety and clinical efficacy of epidural steroid injections for treatment of pain associated with lumbar spinal stenosis. This prospective, randomized, double-blind controlled trial (RCT) will test the hypothesis that the effectiveness of epidural steroid injections (ESI) plus local anesthetic (LA) is greater than epidural injections of LA alone in older adults with lumbar spinal stenosis.
