The effect of iliopsoas exercises on low back pain, function, and range of motion

The purpose of this study was to determine if 6 weeks of iliopsoas exercises would relieve low back pain and increase range of motion. Twenty-four men and women (25-65 years) with self-reported low back pain were randomly assigned to exercise either once a day (Group 1, n=7), twice a day (Group 2, n=7) or were in the control group (n=10). Surveys regarding pain and function were taken by all participants at baseline, 3 weeks, and 6 weeks. Measurements of lumbar and hip flexion were also obtained. A significant improvement (p < .05) in low back pain over 6-weeks was found in both exercise groups. A significant increase in lumbar flexion was found in exercise Group 2. No significant difference was found in function or hip flexion. In conclusion, exercising the iliopsoas results in decreased low back pain, but may not be a beneficial approach in improving function.
