DOI: http://doi.org/10.47211/idcij.2020.v07i04.007 ABSTRACT Background of the study: Acute low back pain is the commonest problem human body suffers with second to common cold. Back pain leads to loss time from work. Loss of productivity, health care costs, financial compensation and various psycho social problems. Muscle energy technique is a system of manual therapy for treatment of movement impairment that combines the precision of passive mobilization. Pelvic tilting exercises in the sagittal plane are generally used to correct the alignment of the lumbar spine of patients with lower back pain. A posture that reinforces lumbar lordosis was identified as one of the main causes of low back pain. Objective of the study: The objective of the study is to find and compare the effects of muscle energy technique on quadratus lumborum and active posterior pelvic tilt exercises on pain and disability in acute low back pain patients. Methodology: Twenty clinically diagnosed acute low back pain patients were selected based on the inclusion and exclusion criteria. They were randomly allocated into two groups (Group A and Group B) consists of 10 subjects each. Group A received muscle energy technique on quadratus lumborum and group B received active posterior pelvic tilt exercises. Intervention lasted for 5 days and 30 minutes per day. Pain and disability were measured before and after 5 days of intervention by visual analog scale and oswestry disability index respectively. Conclusion: Both muscle energy technique on quadratus lumborum and active posterior pelvic tilt exercises reduced pain and disability in acute low back pain patients. When comparing both muscles energy technique on quadratus lumborum is more effective than active posterior pelvic tilt exercises in reducing pain and disability among acute low back pain patients.
