Such persistence may help explain the high recurrence rates of low back pain. As it contracts, it stiffens the vertebrae, giving about two-thirds of the muscle stability for the spine. It is thought that the unique design of the multifidus endows it with extra strength. They can even be used to reduce pain and delay knee replacement for more severe arthritis. The Multifidus Muscle as It Relates to Function. The resulting shorter "excursion" of the deep layer of the multifidus means that when the muscle contracts, it contributes to more compression type motion at the spinal joint it affects — but less rotation — compared to other back extensor muscles (including the more superficial layers of the multifidus itself.). Williams & Wilkins. DISCLAIMER: The procedures and claims made about particular procedures on or through this site have not been evaluated or approved by the FDA.

McDonald and his team mention other studies demonstrating that a multifidus contraction controls the motion of uninjured low back joints, and increases the stiffness (and therefore the stability at) injured low back joints. The multifidus muscles run the length of the spine, and they are an important component of spine stability and posture.
