Quadratus Lumborum

The quadratus lumborum is the most significant abdominal muscle in terms of depth. It can be located in the lower back on either side of the lumbar spine. It stretches from your ribcage to the apex of your pelvis. Because of how frequently this muscle is utilized in daily life, it is not uncommon for it to hurt. The quadratus lumborum is the most common cause of lower back pain, and it can be detrimental to your health. The quadratus lumborum, often known as the quadratus lumborum, is a pair of posterior abdominal wall muscles on the left and right sides. It is located at the back of the abdomen, as the name suggests. Each one is a quadrilateral with its shape.

Quadratus Lumborum muscles:

The quadratus lumborum muscles attach to all four upper lumbar vertebrae’s transverse processes, as well as the lower back’s posterior border. The lumbar spine bends to the side, the pelvis lifts, or both when one of the two muscles contracts. Extensive muscle contractions in the upper and lower back cause the lumbar spine to stretch and gluteus medius pain.

In the back of the spine, there are three quadratus lumborum muscles, those on either side of the iliac crest and those on either side of the 12th rib. Due to the complexity of the muscular system, it is difficult to pinpoint exactly what happens when muscle fibers contract. The thoracolumbar fascia includes it. A quadratus lumborum abnormality may or may not be the underlying cause of back discomfort. The quadratus lumborum can act as a focal point for the forces generated by the surrounding muscles, shifting tensions in different directions. The quadratus lumborum is a significant access site for anesthesia during the back and lower limb surgery because of its strategic location and entropic fiber composition.

Causes of Quadratus Lumborum Pain:

A multitude of reasons might cause pain in the quadratus lumborum, including the following:

The quadratus lumborum muscle contracts or tightens consistently while you sit for a lengthy amount of time. If you stretch your muscles constantly, you will become weary. When the blood supply to a muscle is cut off, the muscle can stiffen and become painful. 

The quadratus lumborum can be aggravated by poor standing or sitting postures, causes pain in the hips. Hip pain and stress can be caused by poor postures, such as slouching, drooping to one side, or sitting without back support.

Because the muscles that surround the quadratus lumborum are weak, other muscles must work harder than they should and result in tight hips.

The quadratus lumborum has to work harder to keep the body steady when the back and pelvic muscles are weak. The quadratus lumborum muscles can stiffen and become overused over time.

If a person’s legs are extended unevenly, the quadratus lumborum may be strained. The pelvis on one side may be higher if one leg is shorter than the other. As a result of the pelvic tilt, the quadratus lumborum may shorten and strain.

Overuse, tension, or strain can cause quadratus lumborum pain. Pain and stiffness can be caused by muscles that are either weak or too tight.

Sitting for lengthy periods might limit blood flow, particularly in the QL and surrounding areas. Pain and bad posture can also be caused by repetitive work and weak back muscles.


As a result of any of these factors, you may twist, bend, or lift inappropriately, increasing your strain. Furthermore, the QL may become overly tight when it adjusts to maintain the stability of your spine and pelvis. Accidents and leg length mismatches can also cause pain in this area.

Ignoring your QL discomfort and allowing it to fester has consequences. As your body compensates for an uneven component, more imbalances and misalignments may occur. Throughout treatment, the pain is likely to intensify and spread to other places of your body.
