Physicians at the University of Alabama at Birmingham Pain Treatment Clinic are offering a new treatment for chronic low back pain. The new treatment offered through UAB Medicine focuses on stimulating one of the key stabilizing muscles of the lumbar spine, the multifidus muscle, which is often dysfunctional in patients after injury or stress to the spine, spinal discs or other soft tissues surrounding the spine. Neural inhibition, or impaired control, of the multifidus muscle can cause a lack of spinal support and lead to chronic pain.
