A Randomized Comparative Study to Evaluate the Efficacy of Sustained Natural Apophyseal Glide Versus Mulligans Bent Leg Raise Technique Along With Traditional Physiotherapy in Patients With Non Specific Mechanical Low Back Pain

This randomized comparative experimental study aims to evaluate and compare the effectiveness of two manual therapy techniques Sustained Natural Apophyseal Glide SNAG and Mulligans Bent Leg Raise BLR when used alongside traditional physiotherapy in the treatment of non specific mechanical low back pain NSMLBP. A total of 58 participants aged 18 to 60 years will be randomly assigned into two equal groups. Group A will receive SNAG with traditional physiotherapy while Group B will receive Mulligans BLR technique with traditional physiotherapy. Both groups will undergo treatment three times per week for four weeks. Outcome measures including pain measured by Numeric Pain Rating Scale NPRS functional disability assessed by Oswestry Disability Index ODI lumbar range of motion measured by goniometry and the Straight Leg Raise SLR test will be assessed at baseline mid intervention second week and post intervention fourth week. The study seeks to determine which manual therapy approach provides superior clinical outcomes in pain relief mobility and functional improvement in patients with NSMLBP.
