PSOAS / ILIACUS Muscles Are The Boss!

PSOAS / ILIACUS Muscles Are The Boss!

It would not be unusual if you haven't heard about psoas major and iliacus muscles. They are often the most misunderstood and least treated muscles. Most people think of them only as a hip flexors. It's a lot more than a hip flexor! The psoas stabilizes the lumbar spine and trunk and the iliacus stabilizes the pelvis. These muscles can be the number one cause of low back pain when dysfunctional.

Psoas major/iliacus are crucial to form a powerful triangular of support at the epicentre of your body, attaching to the lumbar spine, ilium (hip bones) and femur. The direction of the muscle fibre, tension and the line of pull is important for correct function.

Everyone knows the infamous structure of the Eiffel tower; built in 1889, it stands 320 meters tall and weighs over 10,000 tons. Utilizing an intricate lattice frame work it follows precise engineering principles. It is shown metaphorically below in relation to the spinal column and the psoas major and iliacus muscles.

Notice similar principles of structural engineering within the human body. Our spinal column is a tower like structure and needs a solid foundation to stabilize it against sheering forces. These images clearly show that the psoas muscles are not only hip flexors but act as centralized load stabilizers and play a key role in supporting our structure.

STAMINA Academy has identified the psoas muscles as Primary Stabilizing Load Management Muscles with a registered trademark. Further blogs will explain how the psoas/iliacus muscles provide protection for the ligament and multiple joint structures.

All About Muscles

ALL ABOUT MUSCLES

Generally, we don't give our muscles much thought unless we start noticing stiffness, resistance to movement or pain.  It's important to understand that our muscles are interconnected, working like a system of pulleys and cables to stabilize and operate our joints. Some muscles have significantly greater roles than others in stabilization and function.

To understand how some muscles more than others stabilize the skeletal frame let's use a simple analogy : the walls in your house. There are load bearing and non-load bearing walls. The positioning of load bearing walls is critical to the structural integrity of a building. They hold and distribute weight from the roof of the structure to the foundation. If a load bearing wall is weakened or poorly constructed then walls can crack, floors sag and even the whole building can collapse. Secondary walls act as braces or supports to the primary load bearing walls.

This is similar to the muscles in your body, some muscles are key players or foundational to the integrity of the whole muscular system. If these key muscles become weak or unstable it has a domino effect on the other muscles. Secondary muscles compensate in attempt to do jobs they are not designed to do. This causes problems such as joint disease, lesions, ligament instability and other problems. 

STAMINA has identified 38 key muscle groups responsible for stabilization and load management in the body. These muscle groups are referred to as Stabilizing Load Management Muscles with a registered trademark through STAMINA Academy Inc. When your stabilizing load management  muscles are optimally aligned then compensation is eliminated along with painful or debilitating symptoms.
