Back Pain and the Psoas muscle

What is the Psoas Muscle? One of the many causes of back and hip pain is the psoas muscle. The psoas muscle is one of the most important muscles in the body. Pain created by the psoas includes: low back pain,, sciatica, sacroiliac pain spondylolysis, disc problems, scoliosis, hip degeneration, knee pain, menstruation pain, infertility, and digestive problems and biomechanical problems like pelvic tilt, leg length discrepancies, kyphosis, and lumbar lordosis.

This powerful muscle runs down the lower mid spine beginning at the 12th thoracic vertebrae connecting to all the vertebral bodies, discs and transverse processes of all the lumbar vertebrae down across the pelvis to attach on the inside of the top of the leg at the lesser trochanter. The lower portion combines with fibres from the iliacus muscle, which sits inside the surface of the pelvis and sacrum, to become the Iliopsoas muscle as it curves over the pubic bone and inserts on the lesser trochanter.

What is the function of the psoas?

The functions of the Psoas muscle is a hip and thigh flexor, which makes it the major walking muscle. When the legs are stationary the action of it is to bend the spine forward, if sitting it stabilizes and balances the trunk. The lower psoas brings the lumbar vertebrae forward and downward to create pelvic tilt. A sign if you have a tight psoas and if you stretch when standing and tilt your pevlis forward this means your psoas is tight and needs to be massage.

What is pain symptoms of the psoas? If the muscle contracts due to injuries, poor posture, prolonged sitting, or stress, it can alter the biomechanics of the pelvis and the lumbar, thoracic and even cervical vertebrae. Typical dysfunctional of psoas is a referred pain down the front of the thigh and vertically along the lower to mid spinal column. This will trigger pain above the path of the psoas on the abdomen. Frequently the quadratus lumborum muscles develop pain due to the tightness of the psoas, as well as the piriformis, gluteals, hamstrings, and erector spinae.

The psoas can torque your spine to the right or left leaving an imbalance, pulling it forward and twisting the pelvis into various distortions. When imbalance occurs one side of psoas will shorten and pull the spine or pelvis to our dominant one side. The distortions of the spine and pelvis can also show up as a short or long leg. This can result in scoliosis, kyphosis, lordosis and spasms in back muscles trying to resist the pulling of the psoas. It can also pull the spine downward, compressing the facet joints and the intervertebral discs of the lumbar spine. The pressure can cause the discs to degenerate, becoming thinner and less flexible. This degeneration makes the discs more susceptible to bulging or tearing, especially with twisting and bending movements.

What keeps the psoas in contraction? The psoas will stay contracted because of postural habits and trauma. Sitting through much of the day causes the muscle to shorten to keep us bio-mechanically balanced in our chairs. Over time we develop a normal way of holding the psoas that is dysfunctional, unresolved trauma can keep the psoas short and reactive.
