Background: Lumbosacral radiculopathy is a common entity in clinical practice and is frequently caused by disc herniation or degenerative changes in vertebrae. Most patients recover with conservative care, including physical therapy. Objective: The purpose of this study was to evaluate the immediate neurophysiologic effect of transcutaneous electrical nerve stimulation on the pain intensity and H-reflex in patients with lumbosacral radiculopathy. Methods: Twenty male patients (age ranged from 27-49 years) with chronic unilateral lumbosacral radiculopathy and 20 matched healthy subjects participated in this study. Pain intensity and H-reflex latency and amplitude were measured at baseline level and immediately after transcutaneous electrical nerve stimulation application for 20 minutes. Results: The results revealed improvement in radicular pain after application of transcutaneous electrical nerve stimulation with no significant changes (P>0.05) in H-reflex latency and amplitude immediately after transcutaneous electrical nerve stimulation application in comparison to the baseline values. Conclusion: It can be concluded that transcutaneous electrical nerve stimulation application is effective in reducing pain with no immediate effect on the H-reflex parameters elicited from the compressed nerve root.
