Effect of Muscle Energy Technique on Lumbar Hyperlordosis in Asymptomatic Adults

Background: Excessive lordosis is one of the most common postural abnormalities of the lumbar region.Purpose: This study was conducted to investigate the effect of muscle energy technique on lumbar hyperlordosis in asymptomatic adults.Subjects: Forty-six subjects aged from 18-30 years from both sexes randomly divided into two groups with equal numbers.Material: Study group received postural correction exercise and post isometric relaxation for hip flexors and back extensors, while control group received postural correction only. Absolute Rotatory Angle (ARA), pelvic inclination angle and lumbar flexion and extension Range of Movement (ROM) were taken at two intervals pre-treatment and post-treatment.Results: Statistical analysis indicated that there were significant effects of the tested group (the first independent variable) on the all tested dependent variables; absolute rotatory angle, pelvic tilting angle, ROM of lumbar flexion, and extension (F=8.152, p=0.0001 *) and this significant difference in favor of Group (A) than Group (B).Conclusion: Muscle Energy Technique (MET) is considered as an effective factor in improving excessive lumbar lordosis.
