The pull of a tight psoas muscle can take many forms and changes considerably as the muscle gets tighter. We’ll start by looking at what a well aligned psoas muscle can do for the body.
The psoas major, piriformis and gluteus maximus, are the only three muscles in the body that connect the legs to the spine. Together they essentially keep the pelvis and trunk upright on top of the legs. When you have a tight psoas muscle it is often on one side. In many instances both psoas can be tight but most often we are dealing with tightness on one side.
If the psoas muscle is happy it keeps the lumbar spine in its natural curve and allows the muscles of the spine to lengthen up supporting the whole trunk. But lets say that on the left side you have a tight psoas muscle, that leg bone will be pulled up into the hip socket slightly. This accounts for the concept of leg length discrepancy. We all have one leg shorter than the other and this is almost always the result of your tight psoas muscle. In some cases there might actually be a bone size difference, especially in the case of blunt force trauma such as car accidents and such. But for the most part our leg length discrepancy is due to a tight psoas muscle.
The pull of the tight psoas muscle that you can see in the picture above is a fairly classic pattern. I know that at any of my workshops I’ll be able to bring numerous people to the front of the room that exhibit this exact pattern.
And this pattern can be the cause of a many different manifestations of pain. Lower back pain, hip pain, groin pain and the list goes on. Releasing the psoas via exercises and posture work can help you find relief that we often think is no longer available.
When one psoas is tighter than the other, the leg is pulled up into the hip socket on the tight side and since one of the basic functions of the psoas is external rotation, that leg is often turned out more than the other.
In the trunk the image above shows that a tight psoas muscle can shorten the body on the tight side. This tightness manifests by a pulling up on the hip socket and a pulling down on the shoulder drawing the two bony landmarks closer to each other.
This is a little counter-intuitive because you might be thinking that if the right hip is higher the right shoulder should be higher as well but the tight psoas constricts that entire side of the body.
This is just one variation on the pull of a tight psoas. More severe tightness can lead to scoliosis and in extreme cases even a hunchback.
Gentle release work that almost anyone can do can help you find relief from so many nagging issues that often go undiagnosed and leave you without any hope of healing because doctors, MRI’s and x-rays often report that there seems to be no problem.
