To compare between immediate effect of SNAG and mulligan lion position in range of motion (ROM) , pain, functional ability and kinesiophobia on patients with nonspecific low back pain.

Low back pain (LBP) is a global health problem.Orthopedic Manual therapy (OMT) is most commonly recommended form of treatment of LBP and it is also frequently used in clinical practice in various countries. Mulligan introduced a new technique in manual therapy. Mulligan has a great role in the treatment of LBP.General techniques of mulligan are MWM, SNAGs and natural apophyseal glides (NAGs).

Lumber SNAG have immediate and short term on pain and function in treatment of patients with NSLBP.Mulligan has special techniques, one of them is modified lumbar SNAG (lion position) .It has short term effect in reducing pain and activity limitation. Up to investigated knowledge, No previous studies comparing immediate effect of two techniques in range of motion (ROM), pain, functional ability and kinesiophobia
