Where Is the Ql Muscle?

The quadratus lumborum (QL) is your deepest abdominal muscle. It's found in your lower back, between the top of your pelvis and your lowest rib. The QL supports good posture and helps stabilize your spine when you bend to the side or extend your lower back.

What does QL pain feel like?

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.

Where is QL located?

Generally, the QL muscle is located medially to the aponeurosis of the transverse abdominal 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.
