Psoas Major Function: Summary of Psoas Major Function
Looking at the psoas major from a biomechanical perspective might be the key to understanding this elusive and controversial muscle.
Psoas Major Function: Psoas Major and Fascial Pulls
The psoas major’s has extensive fascial connections. The psoas major is part of the deep front line myofascial meridian (anatomy train).

The psoas major crosses the hip and spinal joints. However, it is often overlooked that the psoas major also crosses the sacroiliac joint.
Psoas Major Function: Stabilization of the Spine by the Psoas Major
A healthy joint is both mobile and stable. However, some sources are concerned about the psoas major’s compression/stabilization effect upon the spine.
Psoas Major Function: Spinal Joint Actions – Sagittal Plane
The psoas major’s sagittal plane lumbar spine joint action is by far its most controversial function. The term “psoas paradox” describes this controversy.
Psoas Major Function: Spinal Joint Actions – Frontal and Transverse Planes
The frontal plane spinal action of the psoas major is fairly clear; it crosses the spinal joints laterally, so it lateral flexes the spine to that side.
Psoas Major Function: Hip Joint Actions – Transverse Plane
The function of the psoas major has been claimed to be both medial rotation and lateral rotation. However, most sources agree that it is a lateral rotator.
Psoas Major Function: Hip Joint Actions – Frontal Plane
If the psoas major frontal plane open-chain action is abduction of the thigh at the hip joint, the closed-chain action is depression of the pelvis.
