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

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
