mul·tif·i·dus mus·cle

(mŭl-tif'i-dŭs mŭs'ĕl)
Origin, from the sacrum, sacroiliac ligament, mammillary processes of the lumbar vertebrae, transverse processes of thoracic vertebrae, and articular processes of last four cervical vertebrae; insertion, into the spinous processes of all the vertebrae up to and including the axis; action, rotates vertebral column; nerve supply, dorsal primary rami of spinal nerves.
Synonym(s): musculus multifidus lumborum [TA] , musculus multifidus [TA] .

However, no significant differences were observed in the AIS group between the directions of scoliosis, which does not support a possible theory of a specific (associated with the direction of the scoliosis) type of abdominal muscle asymmetry, as in case of the multifidus muscle.
The present study shows that there was no difference in lateral abdominal muscle thickness and L4 multifidus muscle CSA in adolescent soccer players with and without LBP in four categories including those who experienced LBP during their sports life, during last year, last month, and those with LBP that became worse with sports activity.
The clinical utility for the use of ultrasound for assess the cross-sectional area of the multifidus muscle in LBP patients continues to grow (25).

2-5) The startle response increases neck muscle activity and increased activity in the posterior neck muscles, in particular the cervical multifidus muscle, may exacerbate strains in posterior neck structures (i.
Because the body weight is supported by one knee and elbow in the birddog position, which is an unstable status, the torque of the arm and leg is greater and the multifidus muscle shows a higher activation potential.

While this action helps prevent entrapment of the capsule by the articular surfaces (and any resultant associated pain), this functionality may be impaired in the compromised multifidus muscle.
Studies comparing changes in lumbar multifidus muscle size with EMG activity need to investigate different contraction strategies in wider ranges of muscle contractions.
Embedded in areolar tissue the thoracic dorsal rami accompanied by arteries and veins passes over the dorsal aspect of the multifidus muscle covered by fibres of semispinalis (Chua & Bogduk 1995).
