Muscles of the Back

Your back supports and stabilizes your spine, enabling you to move freely, stand tall, and breathe deeply. While injuries to back muscles in Fairfield, CA, are all too common, proactive visits to Dr. Michael Wilson of Kosak Chiropractic are essential to staying pain-free.


The trapezius muscle is a muscle pair on either side of your shoulder blades that help stabilize and support the shoulder blades and upper back. It also facilitates movements within your shoulders, such as shrugging, tilting, turning, and extending your neck.

Tightness and pain in your trapezius muscle tissue can be caused by bad postures, such as sitting at a desk with hunched shoulders for extended periods. 


Rhomboids attach the shoulder blades to the spine and control scapular retraction when performing upper body movements such as pulling them together or down. Strong rhomboids provide reasonable scapular control, which is necessary for the performance and everyday living.

When it comes to developing rhomboids, you'll need to target them with some specific exercises. 

Dr. Wilson can provide exercises and stretches to keep your back muscles healthy in Fairfield, CA.

Latissimus Dorsi

The latissimus dorsi is one of the largest muscle groups in the back. It plays a vital role in shoulder flexion and extension movements.

Near its midline, it is covered by the trapezius muscle, working in conjunction with the latissimus dorsi to support your shoulders when they are overhead.

Erector Spinae

The erector spinae muscle group is an important core muscle. Not only does it keep your back straight and torso upright, but it also assists with certain head movements.

This muscle group concentrically and eccentrically extends the spine and controls its flexion and extension during exercise or daily activities. They are an integral part of core stability which may help prevent or treat low back pain.


The multifidus is a significant core muscle stabilizer of your spine and provides central support between multiple joints. 

The multifidus comprises fleshy and tendinous fasciculi that fill the grooves on either side of the spinous process in vertebrae. 

The lumbar spine must be supported by multiple bones, each of which must be strong to bear its weight. Thus, if you suffer from low back pain, strengthening and developing this muscle may help alleviate some symptoms.

Quadratus Lumborum

The quadratus lumborum is a sizeable lateral muscle to each side of the spine. 

When both sides of this muscle contract, they help with extension and lateral flexion of the trunk. The QL supports the lower back in various ways and is essential for breathing.
