More Information about the Multifidus Muscle

The multifidus or multifidi spans three joint segments, and works to stabilize the joints at each segmental level.  Working in a synergy with the transverse abdominus, internal oblique and deep erector spinae, the multifidus muscle and deep stabilize the lumbo-pelvic-hip complex during functional movements.

The multifidus also acts as a nuetralizer counteracting the unwanted actions of other muscles.
