Abstract
Objective: To investigate changes in treadmill walking time and self-reported symptoms following therapeutic exercise, epidural steroid injections (ESI), and/or educational materials in subjects with symptomatic lumbar spinal stenosis. Design: Randomized controlled trial. Setting: PM&R clinic. Participants: 20 subjects randomly assigned to 1 of 4 treatment groups. Interventions: Group 1 received a translaminar ESI; group 2, physical therapy (PT); group 3, ESI and PT; and group 4 (control group), educational materials. Main Outcome Measures: Treadmill walking time, visual analog scale, Quebec Back Pain Disability Scale, Roland-Morris Disability Questionnaire, and the Swiss Spinal Stenosis Questionnaire. Results: Increased walking time after interventions, increased self-reported function, decreased pain, and greater improvement was found in those receiving a combination PT and ESI versus controls. Conclusions: Subjects with lumbar spinal stenosis receiving therapeutic exercise and ESI (group 3) had increased walking time and improved pain and function.
