How ART Can Fix Your Posture

Upper Trapezius

The upper traps run from the base of the skull and cervical spine down to the outer clavicle and acromion. When shortened by adhesions, they elevate the shoulders toward the ears and contribute to chronic neck tension and cervicogenic headaches. In people who carry stress in their shoulders or work at a desk, this muscle is almost always fibrotic.

ART protocols for the upper trapezius involve the practitioner applying deep, specific tension to the adhesion while the patient actively depresses the shoulder and laterally flexes the neck away. This elongates the tissue through its full range under load, shearing apart the scar tissue between fibers.

Levator Scapulae

Running from the transverse processes of C1–C4 to the superior medial border of the scapula, the levator scapulae elevates and downwardly rotates the shoulder blade. When adhered, it creates that deep, burning knot between the neck and shoulder that patients can never quite reach. It's also a primary driver of limited cervical rotation — you can't turn your head fully because this muscle won't release.

ART treatment targets the levator at its attachment points and through its belly, while the patient rotates and flexes the cervical spine to lengthen the tissue against the practitioner's contact. Because of its proximity to the cervical nerve roots, precision is critical — this is not a muscle you can effectively foam roll.

Suboccipital Muscles

This group of four small, deep muscles sits at the base of the skull between C1–C2 and the occiput. They control the fine movements of head nodding and rotation. In forward head posture, the suboccipitals are in a constant state of contraction — they're working overtime to tilt the head back so your eyes can look forward even as your cervical spine juts ahead.

Adhesions here are a primary trigger for tension headaches, as the greater occipital nerve passes directly through (or adjacent to) this muscle group. Scar tissue can literally entrap the nerve, causing referred pain across the back of the skull and behind the eyes. ART releases the adhesions with extremely precise, directed contact while the patient performs chin tucks and cervical flexion.

Pectoralis Major & Minor

Pec major is the large chest muscle everyone knows, but in the context of posture, it's the pec minor that causes the most damage. This small muscle runs from ribs 3–5 to the coracoid process of the scapula. When shortened, it tilts the scapula forward and pulls the shoulder into internal rotation — the classic rounded-shoulder look.

Pec minor adhesions are particularly problematic because the brachial plexus (the nerve bundle supplying the entire arm) passes directly beneath it. A tight, fibrotic pec minor can compress these nerves, causing numbness, tingling, and weakness in the arm and hand — symptoms often misdiagnosed as thoracic outlet syndrome or carpal tunnel.

ART treatment for pec minor involves contact on the muscle belly near its rib attachments while the patient horizontally abducts and externally rotates the arm. For pec major, protocols address each head separately, as the clavicular and sternal fibers have different lines of pull and develop adhesions in different patterns.

Sternocleidomastoid (SCM)

The SCM is the prominent muscle on the front-side of the neck, running from the sternum and clavicle to the mastoid process behind the ear. Bilaterally, the SCMs flex the neck forward; unilaterally, they rotate the head to the opposite side. In forward head posture, the SCMs become shortened and fibrotic as they work to stabilize the head in its anterior position.

Adhesions in the SCM are a major but often overlooked source of dizziness, jaw pain, and headaches. The spinal accessory nerve (CN XI) passes through the muscle, and entrapment here can cause referred pain patterns that mimic migraines. ART protocols address the SCM from its sternal and clavicular origins, with the patient performing controlled cervical extension and contralateral rotation.

Scalenes

The three scalene muscles run from the transverse processes of the cervical vertebrae to the first and second ribs. They laterally flex the neck and serve as accessory breathing muscles. In chronic forward head posture, the scalenes become shortened and develop dense adhesions — and they're dangerous when tight, because the brachial plexus and subclavian artery pass between the anterior and middle scalenes.

Scalene adhesions are one of the most common causes of true thoracic outlet syndrome: compression of the neurovascular bundle causes arm pain, numbness, and cold fingers. ART treatment is highly precise, working the scalene fibers individually while the patient performs lateral flexion away from the treated side. This is delicate work that requires an experienced provider due to the proximity of major vessels and nerves.

Iliopsoas (The Posture Muscle)

The iliopsoas is arguably the most important muscle in postural correction. The psoas major originates from the vertebral bodies and transverse processes of T12–L5, crosses the pelvis, and inserts on the lesser trochanter of the femur. The iliacus lines the inner bowl of the pelvis and joins the psoas at the same insertion.

When you sit for hours, the iliopsoas is held in a shortened position. Over time, adhesions form throughout the muscle belly and at the musculotendinous junction. A chronically shortened psoas pulls the lumbar vertebrae forward into excessive lordosis, compresses the lumbar discs anteriorly, and inhibits the gluteus maximus via reciprocal inhibition — meaning your glutes literally shut down because your psoas won't release.

ART treatment for the psoas is performed with the patient supine. The practitioner applies deep, directed contact through the abdominal wall to reach the psoas along the lateral border of the rectus abdominis. The patient then slowly extends the hip off the table edge, actively lengthening the psoas against the practitioner's contact. This is one of the more intense ART protocols, but it produces dramatic and immediate postural changes — patients frequently stand up and notice their pelvis has shifted back to neutral.

Rectus Femoris

Unlike the other three quadriceps muscles, the rectus femoris crosses both the hip and the knee — making it a hip flexor as well as a knee extensor. Adhesions in this muscle contribute to anterior pelvic tilt independently of the psoas, and the two often develop adhesion patterns simultaneously. ART targets the rectus femoris with knee flexion combined with hip extension, stretching the muscle across both joints simultaneously while breaking down adhesions along its length.

TFL & IT Band

The TFL is a small but powerful muscle at the front-lateral hip that feeds into the iliotibial band — a thick fascial structure running down the outside of the thigh to the knee. When the TFL becomes adhered, it internally rotates the femur, contributes to hip flexion, and pulls the pelvis into anterior tilt. The IT band itself develops adhesions where it interfaces with the vastus lateralis (outer quad) and at the lateral femoral condyle near the knee.

ART treatment addresses the TFL at its origin near the ASIS (anterior superior iliac spine) and works distally along the IT band, breaking adhesions between the band and underlying tissues while the patient performs hip abduction and extension movements.

Quadratus Lumborum (QL)

The QL connects the 12th rib and lumbar transverse processes to the iliac crest. Bilaterally, it extends the lumbar spine and contributes to excessive lordosis. Unilaterally (when one side is tighter than the other), it creates a lateral pelvic shift — one hip appears higher than the other, creating a functional leg-length discrepancy that cascades into compensatory patterns throughout the spine.

QL adhesions are a top cause of deep, one-sided low back pain that feels like it's "inside the hip." ART reaches the QL with lateral contact while the patient performs lateral trunk flexion away from the treated side, elongating the muscle against precisely directed pressure.

Piriformis

The piriformis runs from the anterior sacrum through the greater sciatic notch to the greater trochanter of the femur. It externally rotates the hip when the hip is extended and abducts the hip when the hip is flexed. Its claim to postural infamy comes from its relationship with the sciatic nerve, which passes directly beneath the piriformis (and in ~15% of the population, through it).

A tight, adhered piriformis compresses the sciatic nerve — causing piriformis syndrome, which mimics lumbar disc herniation with pain, numbness, and tingling down the leg. It also contributes to sacroiliac joint dysfunction by pulling asymmetrically on the sacrum. ART treatment applies contact to the piriformis belly while the patient internally rotates and adducts the hip, lengthening the muscle across the nerve.

Thoracic Paraspinals & Multifidus

The deep spinal muscles on either side of the vertebral column become fibrotic and shortened in the lumbar region (contributing to excessive lordosis) and weakened/lengthened in the thoracic region (contributing to kyphosis). ART addresses the fibrotic segments with segmental spinal extension under directed contact, restoring motion to the individual vertebral levels where adhesions have restricted movement.

Subscapularis

This rotator cuff muscle lines the underside of the scapula and is the most powerful internal rotator of the shoulder. In rounded-shoulder posture, the subscapularis becomes chronically shortened and develops dense adhesions that prevent the shoulder from externally rotating to its full range. ART reaches it through the axilla (armpit) with the patient performing external rotation against the practitioner's contact — a release that often produces immediate improvement in shoulder position and overhead mobility.

Diaphragm

The diaphragm shares fascial connections with the psoas and quadratus lumborum. A restricted diaphragm forces the body into an accessory breathing pattern using the scalenes, SCM, and upper trapezius — which feeds directly back into upper cross syndrome. ART protocols for the diaphragm work along its costal attachments, restoring excursion and breaking the cycle of dysfunctional breathing that reinforces postural collapse.

Posterior Tibialis & Peroneals

Postural dysfunction extends all the way to the feet. Collapsed arches (overpronation) caused by adhesions in the posterior tibialis change the entire kinetic chain above — internally rotating the tibia, stressing the knee, and shifting pelvic alignment. ART treats the posterior tibialis along the medial shin and into its attachment at the navicular, restoring the dynamic arch support that influences posture from the ground up.
