Quadratus Lumborum, The Deep Pain in LBP


The QL is a 🗝muscle that the average back pain sufferer needs to get checked out! It will bring you to your knees crawling on all 4 when acting up!

▪️Origin: iliac crest, Insertion: 12th rib and transv. processes of the 1st to 4th lumbar vertebrae.
▪️Innervation: subcostal nerve and branches of the lumbar plexus.
▪️Close proximity to colon, kidneys, diaphragm, iliohypogastric and ilioinguinal nerve.
▪️3 sets of fibers: Iliocostal (Ilium to 12th rib), Iliolumbar (Ilium to Lumbar TVPS), Lumbocostal (Lumbar TVPS to 12th rib)

▪️Essentially, the quadratus lumborum contributes to the stabilization and movement of the spine and the pelvis.
▪️A bilateral contraction leads to an extension of the lumbar spine.
▪️A unilateral contraction leads to the trunk is bent towards that direction (lateral flexion) and it can also hike up the same sided hip.
▪️A contralateral contraction rotates the spine.
▪️It can also cause functional scoliosis if the upper fibers bends one way and the opposite lower fibers bends the other way.
▪️In addition, the muscle fixes the 12th rib during movements of the thoracic cage and this way supports expiration (accessory muscle of expiration).

▪️Your lower back pain over time develops into what seems like a sciatica.
▪️When acting up coughing or sneezing it will bring sharp agonising pain.
▪️People constantly attempting to brace and stabilize their upper body with their hands while they stand or sit.
▪️Being in an upright or sitting posture makes the pain worse but most individuals will experience pain with any movement.
▪️Rolling from side to side after laying face up for some time is extremely painful.
▪️If you’re aware of one leg being genetically shorter than the other and you’re suffering from back pain.
