Hip abductor strengthening may have increased trunk stability, thus decreasing lateral trunk lean toward the stance limb, increasing the lever arm magnitude at the knee, and potentially nullifying a reduction in the knee adduction moment that might have occurred as a result of the exercise program. Longissimus capitis specifically performs the same movements, but on the head instead. All iliocostalis muscles are innervated by lateral branches of the posterior rami of the spinal nerves. Quadratus lumborum is involved in extending the trunk and flexing it laterally to the ipsilateral side. latissimus dorsi. Abduction and Adduction.

We have all seen horrifying kidnapping sequences in films where the abductor nabs a victim and locks them in a car. They are located underneath the multifidus and are most developed in the thoracic region. In contrast, adduction is the movement that pulls a structure toward the midline of the body. • A man who was beaten, tied up and put into the trunk of a car escaped out of the moving vehicle. They are involved in movements of the trunk, mainly flexion and rotation. The rotatores has two parts: Contraction of multifidus produces extension and contralateral rotation of the thoracic spine.
