iliapsoas (ilio-so-as) illiacus & Psoas Major Muscle


ThoracoLumbar Fascia- {Erector Spinae group} {Iliopsoas} {Quadratus Lumborum}

See also {Erector Spinae group} {Iliopsoas} {Quadratus Lumborum}

The thoracolumbar fascia is a deed, thick, membrane which covers the deep muscles of the back in the Thoracic and Lumbar regions. In the Thoracic region it is a thin fibrous lamina which serves to hold together the Extensor muscles of the vertebral column and to separate them from the muscles connecting the vertebral column to the upper extremity. There are two muscles that


Gracilis Pain

The Gracilis muscle’s fibers run vertically downward, passing behind to the medial condyle of the femur, curving around the medial condyle of the tibia, and inserts into the upper part of the medial surface of the tibia, below the condyle (Confusing but see pic below). Because of its attachment the Gracilis muscle is considered a Ad-doctor.

 


Sartorius Pain

The sartorius muscle attaches above from the anterior inferior iliac spine, running obliquely across the upper and anterior part of the thigh. It extends down to the medial side of the knee joint passing behind the medial condyle of the femur to end. It is considered the longest muscle in the body and most bodybuilder refer to it as the “Rope” and is highly desired to show during leg poses in competition.

 Abdominal Movements

{Holding on to the end of the bench with the back of your ankles rather then the tops, engages the hamstrings and flattens the low back against the bench. This position allows for maximum abdominal contractions because it takes out the hip flexors AKA Iliopsosas and quads that pull the lumbar forward and perform the abdominal movement)

{Leg kicks are a very common low ab movement, but actually this is incorrect. Leg kicks only engage the fibers of the hip flexors not the abdominal fibers. The abs are actually in a isometric contrition not the desired isotonic contraction.}

Back Movements

Back Movements.

When we talk about back movements in weight lifting, we are mostly referring to the Latissimus Dorsi muscle because it’s the largest and most visible muscle of all the back muscles. It is the Major Muscle Involved (MMI) and most exercises are focused on the Lats.  The other back muscles like the Rhomboids, Erector Spinae, Quadratus Lumborum  are active with these movements, but are not MMI’s. They are mostly aiding and guiding muscles and actually get worked indirectly. Refer to Latissimus Dorsi-Quadratus Lumborum  & Rhomboids / Erector Spinae for full details on these muscles including their attachments and actions.

iliapsoas (ilio-so-as)-illiacus & Psoas Major together

Back Pain-John The Bodyman on Time Warner Cable.mp4

Attachment:The term iliopsoas (ilio-so-as) refers to the combination of the psoas (so-as)  major and the iliacus muscle at their lower (inferior) ends. Because of this connection they are given  the common name iliopsoas. These muscles are felt (palpated) by pressing threw the abdomen, and easy to feel when swollen.  The psoas minor does not contribute to the iliopsoas muscle.

The psoas major originates along the outside (lateral) surfaces of the vertebral bodies of T12 ( 12th Thoracic vertebrae)   and L1-L5 (1st thru 5th lumbar vertebrae). The iliacus originates in the iliac fossa of the pelvis.

The psoas major unites with the iliacus at the level of the pelvic (iliac fossa) and crosses the hip joint to insert on the very tip (lesser trochanter) of the femur.

Action:The iliopsoas is involved in flexion, which is why it’s considered in the hip flexor group and lateral rotation (supination) of the thigh. If the limb is fixed they involve in flexion of the trunk.

Pain: the Iliopsoas is the main hidden reason for lower back.  Dr. Janet Travell, the mother of myofasical pain and trigger point medicine, named this muscle  as the “Hidden Prankster”!  Sports or prolonged siting are all contributors to this condition due to the repetitive hip flexion movements. Pain due to Iliopsoas inflammation is felt in the low back, hip particularly across the top of pelvic bone (Iliac Crest), groin, buttocks, lower area of the abdominals and higher area of the thigh.

The only real effective way to stretch this muscle is the “Hurdler” stretch because of the pulling from the pelvic girdle and the crossing connection of the Rectus Femorus.
