Are your low back muscles swoll enough? The lumbar paraspinal muscles (the muscles surrounding the lumbar spine) play a vital role with regards to spinal movement and stability. Researchers recently observed a close relationship between increased paraspinal muscle cross-sectional area and lower levels of low back pain-related disability. In other words if you have a good solid foundation of muscle mass in your low back, you are less likely to develop a pain-related low back disability. These findings suggest that treatment of low back disability should incorporate increasing paraspinal muscle size to reduce the disability.
