High-Intensity Laser Therapy Versus Transforaminal Epidural Steroid Injection in Chronic Lumbar Disc Herniation-Related Low Back and Radicular Pain

Официальное название

Comparison of the Effectiveness of High-Intensity Laser Therapy and Transforaminal Epidural Steroid Injection in Patients With Chronic Axial and Radicular Low Back Pain Due to Lumbar Disc Herniation: A Prospective Randomized Controlled Trial

Обзор

This prospective, randomized, single-blinded, controlled clinical trial aims to compare the effectiveness of high-intensity laser therapy and fluoroscopy-guided transforaminal epidural steroid injection in patients with chronic low back pain and lumbar radiculopathy. Eligible patients will be randomized into two parallel groups. One group will receive high-intensity laser therapy, and the other group will receive transforaminal epidural steroid injection. All participants will also receive a standardized home-based exercise program. Outcomes will be assessed at baseline, 2 weeks, 6 weeks, and 12 weeks after treatment. The primary outcome will be pain intensity measured by the Visual Analog Scale. Secondary outcomes will include functional disability, neuropathic pain symptoms, quality of life, and functional walking capacity.

Подробное описание

Low back pain is one of the most common musculoskeletal complaints and may lead to substantial disability and reduced quality of life. Lumbar disc herniation is a frequent cause of chronic axial and radicular low back pain.

High-intensity laser therapy is a non-invasive physical therapy modality with analgesic, anti-inflammatory, and biostimulatory effects. Transforaminal epidural steroid injection is a minimally invasive interventional treatment commonly used for radicular pain associated with lumbar disc herniation.

This prospective randomized controlled trial will include adult patients aged 18 to 65 years with chronic axial and radicular low back pain due to lumbar disc herniation. Participants will be randomized into two parallel groups. One group will receive high-intensity laser therapy for 15 sessions over 3 weeks, and the other group will receive fluoroscopy-guided transforaminal epidural steroid injection. All participants will receive a standardized home-based exercise program. Outcomes will be assessed at baseline, 2 weeks, 6 weeks, and 12 weeks after treatment.

Вмешательства

• Устройство High-Intensity Laser Therapy
  High-intensity laser therapy will be applied using a pulsed Nd:YAG laser with a wavelength of 1064 nm. Treatment will be delivered in 15 sessions over 3 weeks to the lumbar paravertebral region. Each session will last approximately 10-12 minutes with a total energy dose of 2500 joules.
• Процедура Transforaminal Epidural Steroid Injections
  Fluoroscopy-guided transforaminal epidural steroid injection will be performed by an experienced physical medicine and rehabilitation specialist. After confirmation of needle placement with contrast medium, 2 mL of 2% lidocaine hydrochloride and 8 mg/2 mL dexamethasone will be administered.
