In this article we will discuss about Psoas major muscle. So let’s get started.
Psoas major muscle
It is divided into two part; superficial part arises from the lateral surface of T12, L1-L4 and neighbouring intervertebral discs and deep part originates from the transverse process of L1-L5 and gets inserted into the lesser trochanter of femur along with iliacus, thereby forming iliopsoas. It is innervated by the lumbar plexus, L1-L3 and artery supply is through the lumbar branch of iliolumbar artery. It’s chief action is flexion of hip along with that it also causes lateral rotation and adduction of hip and unilateral contraction bends the trunk laterally while bilateral contraction raises the trunk from supine position. Clinically, Psoas syndrome is a very rare condition occurs when psoas muscle gets injured causing lower back pain. It is often misdiagnosed. Athletes are more prone to this disease. Physiotherapy is treatment of choice for psoas syndrome.

Will Cortesteroid shots in back joints help to make PT more bearable?
Yes corticosteroid shot are powerful painkillers and provide long term symptomatic pain relief but they don’t cure the cause once it’s effect is gone the pain will relapse and long term use of corticosteroid may cause increased drug tolerance resulting in reduced effectiveness of that drug in future.
But if I’m able to exercise with much less pain, then when it wears off I should be in better shape, yes or no? Thx
absolutely.
Thank you for confirming what I hoped to be true!!
Try to continue pain free exercises avoiding sudden jerky or high velocity movements. Do graded exercise within painfree ROM
Thank you. I was told today that my main issue is my core.
