Quadratus Lumborum – Symptoms, Causes and Treatment

What is Quadratus Lumborum? 

The Quadratus Lumborum muscle informally known as QL is the deepest abdominal muscle which can be referred to as back muscle but is actually part of the deep core. The QL muscles are located on both sides of the lumbar spine. They attach to the iliac crest of the pelvis in the lower back region, between the pelvis and lowest rib. 

Just like any other muscle in a human body, QL is an important muscle as it plays an essential role in stabilizing the pelvis when a person is sitting or standing with a straight back. It also supports the core of the body when breathing. The QL muscle is the main source of lower back pain and might also affect a person’s physical well-being. The QL pain interferes in a person’s daily life in a way that he/she suffers from pain while sitting, standing, or walking. 

The QL Pain and Symptoms of QL Dysfunction  

QL pain is a low back pain which is explained as a deep aching pain that discomforts the muscle that is located deep in the lower back on both sides of the spine. The pain may interfere in a person’s everyday activities that involve standing, walking, sitting but it gets sharp at the specific movement that is while sneezing or coughing. This pain can refer to the groin and mimic sciatica symptoms and the person might have one side of the pelvis raised higher than the other. The QL pain can be acute or chronic, which means either for 2 to 4 months or long-lasting which might affect a person physically. For example, if a person’s Quadratus Lumborum gets tight and painful it may affect their posture, like the way they stand or sit which will eventually lead to other body parts being stressed like the hip gets to suffer and this causes further injury.


There are many causes of Quadratus Lumborum pain which include:

1)   Poor Posture

A poor posture while sitting or standing may stress the Quadratus Lumborum which leads to pain. Sitting without back support, leaning to one side, or slouching will cause the muscles to get tight and stiff.

2)   Sitting for too long

Activities involving sitting for a long time period cause continuous contraction of the QL muscles which reduces the blood flow in certain areas including QL and its surroundings that makes it painful.

3)   Weak Muscles

If the muscles around the quadratus lumborum are weak, it results in other muscles working harder than normal. The QL muscles work harder to support the body and eventually they get overworked and tense. 

4)   Unequal Length of Legs

The uneven lengths of legs may add stress to various muscles of a human body including the quadratus lumborum muscle. If one leg is shorter than the other the pelvis will be higher on the side of the longer leg and even leaning it can stress the muscles and leads to severe pain.

5)   Other Reasons

If a person has suffered from a sports injury or a car accident that has affected the QL, this will cause pain in the QL muscle. 

Everyday activities that involve heavy weight lifting or weight that is uplifted in an incorrect manner will cause the quadratus lumborum muscle to get still and the person suffers from pain.
