- It is the posture muscle. The awakening of the psoas muscle as we came up to stand created the curve of our lower back that allows us to be upright.
- It is the standing muscle. Along with the piriformis the psoas connects the legs to the trunk and together they hold the spine up on top of the pelvis.
- It is the walking muscle. A body working correctly catches itself falling forward through space with each initiation of the psoas muscle.
- It is the trauma muscle. This means different things for different people. Every body processes stress differently but for everyone the psoas is the main storage unit for the body’s response to stimulus. If we don’t sucessfully process and release our stress it will remain in the body and can have debilitating effects on daily functioning both physically and emotionally.
- It is the pain muscle. From my prospective almost all back pain stems from the function/dysfunction of the psoas muscle and the piriformis .
So, what is the psoas muscle? It is the most important muscle in the body that most people have never heard of. But slowly but surely it is making its way into people’s understanding of the body and pain. Learning about the function and use of the psoas muscles can only help us stay healthy and live longer with more vitality.
