Background: Surgery has been known as an inefficient approach to reduce back pain in patients with lumbar spinal stenosis; therefore, non-surgical treatments are necessary. However, there has been little research to analyze the effect of non-surgical treatments on lumbar spinal stenosis pain.
Objective: To identify the effectiveness of 2 physiotherapeutic treatment approaches to relieve pain due to lumbar spinal stenosis.
Design: Randomized controlled trial
Methods: The participants were 36 lumbar spinal stenosis patients who were randomized in the joint mobilization group (JMG) and transcutaneous electrical nerve stimulation group (TENSG). Joint mobilization (JM) was conducted at the posteroanterior joint in the spinous process of the lumbar spine with stenosis. Transcutaneous electrical nerve stimulation (TENS) was applied on the lumbar spine with stenosis at a high frequency and intensity.
Results: Visual analog scale (VAS) pain score significantly decreased in both groups, and the VAS value decreased more after JMG than that after TENSG. The pain thresholds of both groups also significantly increased, and that of JMG increased more compared to TENSG. In both the groups, significant improvements in VAS and pain thresholds were found, and JMG showed better results than TENSG.
Conclusions: JM and TENS showed significant relief in both pain threshold and painpain, and JM showed more advanced relief compared to TENS.
