Comparıson Of Hıgh-Intensıty Laser And Low-Intensıty Laser Therapy In Patıents Wıth Lumbar Dısc Hernıatıon

Abstract

Lumbar Disc Herniation (LDH) is a fragment of the disc nucleus that is pushed out of the annulus, into the spinal canal through a tear or rupture in the annulus. The disc presses on spinal nerves, often producing pain, It is the lumbar region of the spine that often suffers from herniated discs. Nearly all herniated lumbar discs occur between the fourth and fifth lumbar vertebrae (L4-L5) or (L5-S1). One of the most common reasons for back discomfort and even sciatica is a lumbar disc herniation. In order to better understand how effective high-intensity therapy and low-level laser therapy are for persons suffering from a herniated lumbar disc, this study compares the two treatment modalities. However, there is a lack of evaluation in previous studies. In Iraq's Al-Diwaniyah Governorate, this study was carried out at Al-Diwaniyah Teaching Hospital and Al-Hamza General Hospital. Sixty patients with Magnetic Resonance Imaging confirmed lumbar disc herniation, computed tomography (36 males and 24 females) aged between (81-65y) participated. The subjects randomly assigned to participate in one of three treatment groups: high-intensity laser therapy (1064 nm, 7 w), low-level laser therapy (904 nm, 500 mw ), or a placebo laser with exercise 10 sessions total. The visual analogue scale (VAS), the Oswestry Disability Index (ODI), the Roland-Morris Disability (RMD), and the Schober's test used for evaluation the efficacy of therapy. Both pre- and post-irradiation measurements were taken. High-intensity laser therapy was found to be significantly better than low-intensity laser therapy in terms of resting pain in patients with lumbar disc hernia after 3 weeks (p<0.05). Low-intensity laser therapy was found to be significantly better than the placebo group in activity pain (p<0.05). In addition, high-intensity laser therapy was found to be significantly better in all parameters compared to the placebo groups (p<0.05). The HILT and LLLT groups showed better improvement in some parameters than the placebo group.
