Background: the purpose of this study was to assess the effect of Active stretching of tight and weak quadratus lumborum muscle.

Method: 56 healthy subjects were included in this study. The age between 20-50 years. Subjects were selected randomly and conveniently allocated into 2 groups (group A and B ) Active stretching of tight and Weak QL. Before and after the treatment subjects were assessed and analysed with Range of motion ( Lumbar side flexion and extension ) for strength QET.      

Result: Pre and post treatment protocol was analysed using paired t test and Unpaired t test. Unpaired t test analysis showed that ( significant effect for Lumbar side flexion p=0.0320 and wasn’t significant for Extension p=0.9330 ) and extremely significant for QET (p=0.0001).

Conclusion: The effect of active stretching of QL enhances increase in Range of motion and strength subjects with Tight and weak QL muscle.
