What is the function of the quadratus lumborum muscle?

The anatomy texts describe the quadratus lumborum muscle as an extensor of the lumbar spine, a stabilizer of the lumbar area, capable of tilting laterally and capable of acting as an inspiratory accessory muscle.

Quadratus Lumborum Fixes the 12th rib to stabilize diaphragm attachments during inspiration. Lateral flexes the vertebral column. Extends lumbar vertebrae. It forms with the contralateral Tensor fascia lata and Gluteus medius a lateral myofascial sling which aims to maintain frontal plane stability of the pelvis.

Function. 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 vertebral column. When the muscle is only activated on one side, the trunk is bent towards that direction (lateral flexion).

Quadratus lumborum trigger points can cause Pain in the lower back, pelvis, and hips. Quadratus lumborum trigger points can cause deep pain in the lower back or a stabbing sensation in the hips or pelvis. It can also cause sharp pain when the QL shortens when coughing or sneezing.

When the glutes are tight from disuse, the QL will compensate by becoming the prime mover of the Hip joint. This results in a gait that hikes the hip upward with each step. Hiking the hip upward in this fashion will lead to compression of the lumbar region due to excessive side bending.

What causes quadratus lumborum pain? Pain in the quadratus lumborum can be due to Overuse, stress, and strain. Sometimes muscles cause pain and stiffness when they’re weak or too tight. Activities such as sitting for long periods of time can reduce blood flow to an area, especially in the QL and surrounding areas.

Background: Quadratus lumborum muscle (QL) is one of several muscles subject to tightness and Relevant to symptoms in the back and hip.

The quadratus lumborum muscle, informally called the QL, is a paired muscle of the left and right posterior abdominal wall. It is the deepest abdominal muscle, and commonly referred to as a back muscle. Each is irregular and quadrilateral in shape.

The hip flexors allow flexion of the hips and the lumbar spine. Having suppleness of these muscles is pivotal to a health strong lower back. The Quadratus Lumborum (QL) muscle is such a important muscle in supporting your spine. It lies laterally to your spine on either side and provides support when you are sitting.

6. Pelvic tilt

1. Lie on your back with your knees bent and your feet in toward your hips.
2. Relax your upper body and tuck your chin in slightly.
3. Engage your core as you press the small of your back into the floor.
4. Hold for 5 seconds. Relax for a few breaths.
5. Repeat 8–15 times.

The most effective way to release the QL massage is by treating the trigger points (the active trigger points are shown in the picture above), where the therapist will use their thumbs or elbow to target these specific spots. The therapist can also use Swedish and Myofascial releases to decrease pain.

QL pain can be described as A dull, aching pain which can become sharp at times from specific movements. Sometimes considered “the joker” of lower back pain, it is often overlooked as the main cause of the pain, with other lower back structures taking the blame.

Quadratus lumborum pain involves discomfort in the muscle that is located deep in the lower back on both sides of the spine. The quadratus lumborum muscle starts at the pelvis and runs up to the lowest rib. It plays an essential role in stabilizing the pelvis when a person is upright.

Signs of QL dysfunction

1. Needing to stabilise your torso on a table with both hands when sitting or standing.
2. Coughing or sneezing causes pain in the lower rib cage.
3. Unable to comfortably roll to one side when supine.
4. General lower back pain.
5. Pain in the gluteus muscles.

The answer to those questions will dictate the course of action taken in restoring its proper function in lateral flexion movement patterning. What Is the Action of the Quadratus Lumborum? The opposite-side quadratus lumborum does the antagonistic muscle action.
