Purpose: Low back pain occurs and frequently recurs in many people. An imbalance of paraspinal muscle activity can cause low back pain. Mulligan's concept of mobilizations with sustained natural apophyseal glides (SNAG) is a common method for treating low back pain. The purpose of this study was to investigate the effects of this method on paraspinal muscle activity in patients with chronic low back pain. Methods: Twenty-one patients with low back pain participated in this study. Patients were classified using the Oswestry disability index. The subjects' paraspinal muscles were measured by surface electromyography both before and after the SNAG mobilization. We measured the root mean square value of the paraspinal muscles during lumbar flexion and extension. Results: Paraspinal muscle activity in patients with chronic low back pain was different between the right and left sides. Importantly, paraspinal muscle activity significantly decreased after using the SNAG mobilization method. Conclusion: This study shows a difference between paraspinal muscle activity in chronic low back pain patients and finds that the Mulligan's concept of SNAG mobilization is effective at reducing imbalances in paraspinal muscle activity in low back pain patients.
