Effects of Application Time of Pulsed Radiofrequency in patients with Chronic Lumbosacral Radicular Pain
Department of Anesthesiology and Pain Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea
Background
Pulsed radiofrequency stimulation has been used to control chronic refractory lumbosacral radicular pain. However, the application time of pulsed radiofrequency has been usually chosen arbitrarily without evidence from the literature. In the present study, we evaluated the effect of application time of pulsed radiofrequency in patients with chronic lumbosacral radicular pain.
Materials and Methods
This randomized controlled study included 62 patients with chronic refractory lumbosacral radicular pain due to lumbar spinal stenosis or herniated intervertebral disc. All patients were received pulsed radiofrequency and were randomly assigned to two groups according to application time: group 6 min, pulsed radiofrequency applied for 6 minutes (n=31); group 12 min, pulsed radiofrequency applied for 12 minutes (n=31). The Numeric Rating Scale (NRS-11) of back and leg, and Oswestry Disability Index (ODI) were measured at baseline, at 1, and 3 months after the procedure.
Results
There was no significant difference between the groups in NRS-11 of back and leg at 1 and 3 months after the procedure (P > .05). In addition, ODI at 1 and 3 months after the procedure did not differ between the groups (P > .05).
Conclusion
Extended application time of pulsed radiofrequency may be not superior compared to conventional application time in patients with chronic lumbosacral radicular pain.
