Chronic mechanical low back pain (CMLBP) is a common clinical problem that affects physical function, spinal mobility, and quality of life. Manual therapy techniques such as Integrated Neuromuscular Inhibition Technique (INIT) and Muscle Energy Technique (MET) are frequently used in clinical practice to reduce pain and improve function. Core stabilization exercises (CSE) have also been reported to enhance spinal stability and neuromuscular control. However, limited evidence exists comparing the combined effects of these manual therapy techniques with core stabilization exercise on clinical outcomes in individuals with CMLBP. This randomized controlled clinical study aims to compare the effects of CSE combined with INIT and CSE combined with MET on pain intensity, functional disability, lumbar range of motion, psychosocial status, muscle endurance, and quality of life in adults with chronic mechanical low back pain. Participants will be randomly assigned to one of two groups: (1) CSE + INIT or (2) CSE + MET. Each group will receive treatment two times per week for six weeks. Pain severity, functional status, lumbar mobility, patient-reported outcomes, and muscle endurance will be assessed at baseline, immediately after the intervention, and at follow-up. The results of this study will help determine whether INIT or MET provides additional benefit when combined with core stabilization exercise for improving symptoms and function in individuals with chronic mechanical low back pain.
