What is the function of the intertransversarii?
The intertransversarii muscles function to flex the spine laterally by approximating adjacent transverse processes. They also help to stabilize adjacent vertebrae during large spinal movements. The thoracic intertransversarii muscles are small and are usually only present in the lower thoracic region.
What nerve Innervates the intertransversarii?
Most of the intertransversarii muscles are innervated by the anterior rami of the spinal nerves, but several muscle pairs in the lumbar subdivision are innervated by the posterior rami instead.
What is origin and insertion for intertransversarii?
Anterior intertransversarii colli originate from the anterior tubercles of transverse process of one cervical vertebra and insert onto the anterior tubercle of transverse process of the adjacent vertebra.
What is the origin of the quadratus Lumborum?
The Quadratus Lumborum (QL) is the deepest back muscle and originates from the iliac crest and inserts on the transverse process of lumbar one through five and the lower part of the twelfth rib. The QL muscle is flattened and has a quadrangular shape.
Where is the quadratus Lumborum?
The quadratus lumborum (QL) muscle resides in the deep and posterior, lateral, and inferior areas of the spine, involving the iliac crest, the transverse processes of the lumbar vertebrae, and the 12th rib.
What causes pain in the quadratus lumborum?
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.
How do you fix quadratus lumborum pain?
How Do I Treat QL Pain?
- Heat: Put heat on the area for 10-15 minutes.
- Stretches: Stretches can help target the QL muscle and give you short term pain relief.
- Keep moving: Movement is important to prevent QL pain from developing or getting worse.
What aggravates QL?
How do you release the quadratus lumborum muscle?
Self Myofascial Release for the QL
- Begin by laying on your back.
- On the same side as the leg with the knee in the air, feel your back and find your last rib.
- Lean onto the ball and take 2-3 minutes to breathe, relax over the ball, and try not to tense up.
How should I sit with QL pain?
Sitting
- Sit as little as possible, and only for short periods of time (10 to 15 minutes).
- Sit with a back support (such as a rolled-up towel) at the curve of your back.
- Keep your hips and knees at a right angle. (Use a foot rest or stool if necessary.)
How do you release quadratus lumborum?
Using a foam roller can be a great way to release tight QL muscles in the lower back. The right foam roller can target and treat these muscles to relive symptoms. Foam rolling can help improve circulation, provide myofascial release, reduce trigger points and allow for better mobility helping you move freely.
