One of the main back stabilizers and hip flexors. If you sit all day the psoas becomes rounded like a banana; then, you stand up, the psoas pulls on your back, making you more prone to pain and lower back injury.
Most doctors neglect the psoas because it lies so deep below the surface of the skin, and therefore is hard to locate. Unlike other deep lying muscles, like the piriformis, stretching the psoas and trying to locate the psoas with your fingers is not easy. When you look at where it lies in relation to the pelvis and the role it has to play, you’ll understand that in both hip, groin and lower back injuries quality and feel of the psoas is paramount.
I have many techniques for effective self-treatment and in-office treatment of this troublesome hip flexor. I also use the DMS and laser on the psoas.
