The multifidus muscle is a series of long, narrow muscles located on either side of the spinal column that help stabilize the lower portion of the spine, called the lumbar spine but it is also referred to as the lumbar multifidus.

The general role of the back extensor muscles — of which the multifidus is one — is to extend the back, which is analogous to making an arching movement. These muscles also contribute to side bending (tilting) and rotation (aka twisting.)

What makes this particular muscle interesting is that it doesn’t insert on the vertebra above the origin. Instead, it skips 2-4 vertebrae to insert. Because the muscle skips vertebrae before inserting, it helps maintain and create the structure of the spine.

Common Dysfunction:

Improper lifting technique can cause strain or injury to the multifidus. For this reason, you should always be cautious to lift with bent knees, keep your back straight, and hold the object as close to you as possible.
