The Influence of Exercise on Perceived Pain and Disability in Patients With Lumbar Spinal Stenosis: A Systematic Review of Randomized Controlled Trials.

Lumbar spinal stenosis (LSS) is an increasingly prevalent condition that has major health and economic implications. While there are many options for the treatment of LSS, exercise is widely considered a first-line intervention as it is associated with reduced complications and cost as compared to more invasive options. Currently, it is not clear if exercise is an effective approach to managing pain and perceived disability in patients with symptomatic LSS. Therefore, the purpose of this systematic review is to evaluate the published literature that has investigated exercise as a primary intervention for LSS. A search was conducted in electronic databases including PubMed, PEDro, SPORTDiscus, CINAHL, and AMED using the key words lumbar spinal stenosis, exercise, physical therapy, rehabilitation, and conservative treatment. Inclusion criteria consisted of published randomized controlled trials written in English that included exercise as the primary treatment in at least one of the groups, and had reported measures of pain and disability clearly stated. The search identified 310 studies of which 5 met all the inclusion parameters. Exercise appears to be an efficacious intervention for pain, disability, analgesic intake, depression, anger, and mood disturbance among patients with LSS. Further research is needed to determine which type of exercise is the most effective in managing symptoms associated with lumbar spinal stenosis.
