Non-specific Lower back pain NSLBP does not have any specific cause and almost 90% of patients experience undiagnosed pathologic LBP. It is multifactorial and has different causes depends on the type of injury. Common etiologies behind NSLBP are muscular weakness, postural instability, fascial restriction, lumbo-pelvic muscle imbalance, change in spinal curvature and abnormal tilting of pelvic.

A randomized controlled trail will be conducted to demonstrate the mutual effects of McGill exercise with and without 3-Dimensional Myofascial release technique on pain, lumbar hyperlordosis LHL and pelvic tilt in patients with NSLBP. Sample size is calculated through Epitool,38 subjects of age 18-55years will be taken. Non-probability convenient sampling will be used to collect data from Riphah rehabilitation clinic Lahore and Private clinical setups of Lahore, by using Numeric pain rating scale (NPRS) for pain, Flexicurve rubber ruler for hyperlordosis, Inclinometer for anterior pelvic tilt from the patients having present complain of LBP without history of traumatic low back injury. A written consent form will be taken from participants meeting inclusion criteria and will be randomly allocated into two groups consisting equal members. One group will receive 3-Dimentional myofascial release with McGill and other group will just receive with McGill exercise. The session will be provided for 40-45minutes, 3 days/week for 6 weeks. All participants will be evaluated at baseline and after 6 weeks. Data will be statistically analyzed by using SPSS Version 29.
