The quadratus lumborum muscles can be the source of back pain when overused, or in association with scoliosis or weak gluteal muscles. Reserve mover actions: Anterior pelvic tilt.Prevents collapse of the vertebral column in the frontal plane (i.e. Vertical stabilization of pelvis, lumbar spine, and lumbosacral junction.Elevates the Ilium (bone), with ipsilateral contraction ("hip hiking").The quadratus lumborum assists the diaphragm in inhalation Fixes the 12th rib during forced expiration.Extension of lumbar vertebral column, with bilateral contraction (based on line of force passing ~3.5 cm posterior 元 rotation axis ).

Lateral flexion of vertebral column, with ipsilateral contraction.The quadratus lumborum can perform four actions: The quadratus lumborum muscle is a continuation of transverse abdominal muscle.Īnterior branches of the ventral rami of T12 to L4. Posterior view showing on the left the relationship of the left kidney to the left quadratus lumborum muscle.Īnterior to the quadratus lumborum are the colon, the kidney, the psoas major muscle, (if present) the psoas minor muscle, and the diaphragm between the fascia and the muscle are the twelfth thoracic, ilioinguinal, and iliohypogastric nerves.
