Scoliosis of quadratus lumbar muscle

Scoliosis involves a lot of muscles, such as psoas major muscle, erector spine muscle, etc. Today, Professor Ye Huiyang mainly discusses the role of psoas quadratus muscle in scoliosis and its impact on scoliosis.

Lumbar quadratus muscle, rectangular flat muscle, located on both sides of the lumbar vertebrae of the posterior wall of the abdominal cavity, deep in the erector spine muscle, has five heads, originating from the iliac crest and iliopsoas ligament, and the end is located at the transverse process of the lumbar vertebrae and behind the 12th rib, covering the lumbar quadratus lumbar muscle and psoas major muscle, which can stabilize the balance of the lumbar spine.

The main function of the lumbar quadratus muscle is to maintain the stability of the pelvis and lumbar spine, and is responsible for the lateral bending and rotation of the body. In scoliosis, this muscle works unilaterally, pulling the transverse process of the lumbar spine to one side, thus causing the lumbar spine to deviate and twist, leading to lumbar scoliosis.

The lumbar quadratus muscle is the main muscle of scoliosis. In posture assessment, if there are more and deeper wrinkles on one side of the trunk than on the other side, it may mean that the lumbar quadratus muscle on the other side is shortened. The problem of scoliosis is not necessarily caused by the lumbar quadratus muscle, but if scoliosis occurs, the lumbar quadratus muscle must be examined and treated.

1. Massage relaxes the lumbar quadratus muscle

1. Massage and relaxation

Massage the lumbar quadratus muscle with your elbow in the direction indicated by the arrow.

Place the massage ball in the position of the lumbar quadratus muscle, bend your knees, and use your body's strength to massage the lumbar quadratus muscle. If the lumbar quadratus muscle is tense, there will be obvious soreness during massage.

3、Use foam shaft massage to relax

The principle of the method is the same.
