The iliopsoas is a pretty cool muscle.
It’s one of the most complex muscles in the body, and it is the only lower back and hip muscle to attach to the front of the spine.
In fact, the iliopsoas is actually two muscles in one: the psoas muscle and the iliacus muscle.
The psoas muscle attaches along the lumbar spine and the intervertebral discs then descends obliquely to attach at the upper inner thigh bone. The iliacus muscle attaches to the upper two-thirds of the iliac fossa then descends to join the psoas major tendon, with some of its fibers attaching directly to the femure near the lesser trochanter.
The primary function of both of these muscles is hip flexion. In other words, these muscles work to lift the knee and take your next step while walking.
Have you ever had a pain that’s right behind your neck and just behind between your shoulder blade and your spine?
It the type of pain that makes most people go crazy trying to reach their hands behind their head to rub their neck and shoulder.
While the pain is commonly associated with the levator scapula muscle, it’s not always the root of the problem.
The Cause of Your Shoulder Pain
When we hear that we have a problem with shoulder pain or our rotator cuff, we usually assume the worst.
Most of us know that the rotator cuff is a very important part of the shoulder. But besides that, most people don’t know much about it.
The rotator cuff is a group of 4 small muscles that hold the humorous (arm bone) into the gleno-humeral joint (the shoulder socket), and helps to stabilize the shoulder.
Every time that you move your hand, like when you type, write, knit, etc, you are using the rotator cuff muscles to stabilize your shoulder and hold your arm bone in place.
So it’s no wonder you feel the pain, we’re using it all the time.
