Subscribe/Renew Journal
[Purpose] The aim of this study was to evaluate the immediate effect of Muscle Energy Technique on Quadratus Lumborum Muscle on pain level and active Lumbar Range of motion in patients with acute and sub acute nonspecific Low back pain. [Subjects and Method] Sixty patients with nonspecific low back pain and limited lumbar ROM were selected. The subjects were randomly assigned to an experimental group(n=30), which received treatment consisting of Muscle Energy Technique to Quadratus Lumborum muscle and hot pack, while that of control group received only hot pack to lower back. Pain levels using NPRS and Lumbar ROM using Modified Schober’s test were measured before and immediately after the interventions in both groups. [Results] Both the groups showed significant improvement in outcome measures. However, the Experimental group showed better results on comparing with control group. [Conclusion] The combination of Muscle Energy Technique to Quadratus Lumborum muscle along with hot pack treatment was found to be effective in reducing pain and improving lumbar ROM after a single intervention session.
