The psoas is one of the most common muscles treated by massage therapists. Most of your clients become very familiar with that discomfort when you find those “sweet spots”.
So what makes the muscle so great? We’ll other than the connection to posture there are some interesting factors that really make it special
First let’s talk about the attachments. The muscle attaches from the lesser trochanter of the femur and goes up to L2-L5. However, if you look past the bones, it also connects into the lumbar discs. That means it can increase strain to those regions if their injured.
Going further in attachment, there are fascial connections that go all the way up to T5. That means it’s not just a low back muscle. If that wasn’t interesting enough, did you know that the longus colli has fascial attachments to T5. Essentially the longus colli and psoas are continuous. That has huge implications when looking at proprioception. That is one reason why both muscles are critical structures when looking at core stabilization.
But why stop at attachments. The second aspect I wanted to mention is function. Deep fibers of the psoas are stabilizer muscles. If they are dysfunctional they don’t stabilize and that has massive implications that I will address in a future post.
I’ll also add that if there is a problem with the lumbar spine or acute injury in the region the psoas clamps down to protect the spine. Ironically, a lot of the time it makes the issues worse because you no longer are able to use the correct musculature.
Also, these muscles work very closely with the erector spinae. In fact, if the psoas is active, so is the erector. These muscles will feed off each other and if one is tight the other with tighten to counter the contraction. This adds to the compression of the spine. That means it’s good to take care of both of these muscles.
So bottom line is that if you see a tight psoas you can expect some big changes for the body if it is addressed. Whether it’s structural changes or stabilization, your clients will thank you for finding these issues. But critically thinking about what is causing the issue can help you find other issues. Think about tight quads or thoracolumbar fascia which will impact lumbar posture and increase strain. This may cause the psoas to tighten back up and you’ll be able to prevent the problem from returning.
