What does psoas muscle tightness affect?

WHAT DOES TIGHTNESS IN THE PSOAS EFFECT?

It’s not uncommon for one psoas (left or right) to become shortened more on one side than on the other.

A shortened psoas is most often the result of continual misuse and poor alignment.

A shortened psoas, can be seen visually as a forward thrusting pelvis.

It can also create a rotational effect on the vertebrae of the spine, the pelvis, and the legs and feet.

In the pelvis, a shortened psoas results in forward thrusts, lateral tilts and twists.

In the femurs, the result of a shortened psoas includes constricted movement in the ball and socket joint and limitations in lateral and medial rotation.

It has two ends and two very different functions.

Because of the attachment of the psoas at the bottom of the front of the ribs, instead of it pulling the ribs down towards the pelvis, when the psoas is tight it actually thrusts the ribs forwards (or lifts the ribs up).

So, to simplify, when the psoas is tight it can:

  1. lift one leg out in front of you (hip flexion),
  2. tuck the pelvis under, and/or
  3. pull the ribs out in front of you

In the past, the psoas used to be lumped in as a just a hip-flexor, but it’s more than just this.
