High-intensity Laser Therapy and Mulligan Mobilization for Patients With Chronic Nonspecific Low Back Pain

Overview

The goal of this clinical trial is to evaluate whether combining high-intensity laser therapy with Mulligan mobilization techniques can effectively treat chronic non-specific low back pain in adult patients aged 18-60 years, including both males and females. The main questions it aims to answer are: Does the combined intervention reduce pain intensity more effectively than standard or single-modality treatment? Does the combined intervention improve functional disability and lumbar range of motion? Researchers will compare high-intensity laser therapy combined with Mulligan mobilization to \[control group: Mulligan alone\] to determine whether the combined approach produces superior clinical outcomes. Participants will: Receive high-intensity laser therapy according to a standardized treatment protocol Undergo Mulligan mobilization techniques administered by a trained therapist Attend multiple treatment sessions over a defined intervention period Complete assessments of pain intensity, functional disability, and lumbar range of motion before and after treatment

Chronic non-specific low back pain is a prevalent musculoskeletal condition associated with pain, reduced functional capacity, and decreased quality of life. Conservative management often includes manual therapy and physical modalities; however, the optimal combination of these approaches remains unclear. High-intensity laser therapy (HILT) has been proposed to provide analgesic and anti-inflammatory effects and to promote tissue healing. Mulligan mobilization techniques, particularly sustained natural apophyseal glides (SNAGs), are commonly used to restore pain-free movement and improve spinal function. While both interventions have shown individual benefits, evidence regarding their combined effect is limited. This pilot randomized controlled trial aims to explore the feasibility and preliminary clinical effectiveness of combining HILT with Mulligan mobilization in adults with chronic non-specific low back pain. The study will evaluate changes in pain intensity, functional disability, and lumbar range of motion following the intervention period. Participants will be randomly allocated to intervention groups, and outcomes will be assessed at baseline and post-intervention using standardized clinical measures. Findings from this pilot study will help inform the design of larger trials and clarify whether a multimodal approach incorporating HILT and Mulligan techniques offers added clinical value in this population.
