OBJECTIVES: To evaluate the clinical outcome of improving pain and functional scale lumbar pulsed radiofrequency, compared to the use of epidural steroids in the treatment of patients with chronic low back pain. TYPE OF RESEARCH: A randomized single and blind. METHODS: The study was conducted from May, 2008 to July, 2009. There were 40 patients, through institutional and private means, in the city of Hermosillo, Sonora, Mexico, with chronic low back pain. The survey was conducted by Roland-Morris and visual analog scale of pain, with previous treatment, and subsequent to it. There were no losses of patients in the follow-up. We analyzed the results of different variables (age, sex, occupation, development, work load, disability, findings on imaging), and compared with the Chi-2 test. RESULTS: They were very similar in both treatment groups (Chi-2 = 2.8283, p = 0.093), with two cases complicated by puncture in the epidural steroid group, without cases complicated by use of pulsed radiofrequency. The values of Chi-2 showed no statistically significant differences, with p-values from 0.09 to 0.9. CONCLUSION: The application of pulsed radiofrequency is as effective as the application of epidural steroids for management of chronic low back pain.
