Effectiveness of High Intensity Laser Therapy (HILT) in Patients With Chronic Lumbar Radiculopathy Due to Disc Herniation.

The aim of the researchers in this intervention study was to see the effects of High Intensity Laser Therapy (HILT) on participants' disability, functionality and pain parameters in chronic radicular low back pain due to lumbar disc herniation, and to investigate its superiority over widely used conventional electrotherapy modalities. The main question it aims to answer is: What is the short and long term effect of high intensity laser therapy on low back and leg pain in patients with chronic lumbar radiculopathy due to disc herniation? 35 patients in group A will receive the planned Hotpack, TENS, High Intensity Laser Therapy (HILT) and exercise treatments for lumbar radicular low back pain. In group B (comparison group) 35 patients will receive Hotpack, TENS, sham HILT, and exercise treatments. Participants will receive 15 sessions of treatment and exercises will be given as a home program. Both groups will complete questionnaires about disability, life functions and pain before and after treatment and at the 3rd month follow-up.
