What Your Upper Cervical Correction Is Actually Doing to the Brain, the Brainstem, and the Dura

Uncategorized Feb 17, 2026

 There is a small cluster of muscles at the base of your skull that contains up to 500 neuromuscular spindle cells per gram of tissue. The large paraspinal muscles of your lumbar spine contain roughly 3 to 5. Your quadriceps, responsible for extending the knee against significant load, contain fewer still. The suboccipital muscles are not prime movers. They were never designed to be. They are sensory transducers, and the signal they generate continuously is feeding some of the most consequential neurological regulation in the human body. [1]

Every PRYT correction you make is working directly on this tissue. The clinical results you observe afterward, including hip range of motion changes, autonomic shifts, visceral tone changes, and blood pressure normalization, are not coincidental findings. They are mechanistically predictable once you understand what this tissue is actually connected to and how those connections work.

This is that explanation.

The Structure Nobody Taught You About Is Running Between Your Correction and the Dura

Uncategorized Feb 11, 2026

 There is a dense fibrous connective tissue structure connecting the suboccipital musculature directly to the spinal dura mater. It passes through the posterior atlanto-occipital and atlanto-axial interspaces. Its fibers consist primarily of type I collagen arranged in parallel orientation, designed specifically to transmit strong tensional forces from muscle contractions to the dural sheath. It is called the myodural bridge complex, and it changes the scope of what you are doing with every upper cervical PRYT correction.

This is not a newly theorized anatomical relationship. It is a documented structure with known mechanical properties, known sensory receptor populations embedded within its own fibers, and measured effects on CSF dynamics. The research on it is recent enough that most practitioners have never encountered it in any formal training context.

One Tissue System, Not Three

The Most Important Hole in the Skull You Are Not Thinking About

The Most Important Hole in the Skull You Are Not Thinking About

The jugular foramen sits at the junction of the occipital and temporal bones, immediately adjacent to the occiput-atlas articulation. Through it passes the vagus nerve, the glossopharyngeal nerve, and the spinal accessory nerve. The vagus and spinal accessory nerves share a large posterior adipose column within the intraforaminal extradural neural axis compartment, separated from the glossopharyngeal nerve by a fibrovenous curtain of meningeal dura.

This is not an academic anatomy detail. It is the structural reason why upper cervical dysfunction has autonomic consequences that most practitioners either miss or attribute to something else entirely.

Two Mechanisms, Not One

When a positive PRYT pattern creates chronic fascial tension and hypertonic suboccipital musculature in the neighborhood of the jugular foramen, two separate things are happening to the vagus nerve simultaneously.

Your Neck Muscles Are Not Doing What You Think They Are

Uncategorized Jan 28, 2026

 There is a small cluster of muscles at the base of your skull that contains up to 500 neuromuscular spindle cells per gram of tissue. The large paraspinal muscles of your lumbar spine contain roughly 3 to 5. Your quadriceps, responsible for extending the knee against significant load, contain fewer still.

 

The suboccipital muscles were never designed to be prime movers. They are sensory transducers, and the signal they generate continuously is feeding some of the most consequential neurological integration in the human body. Every PRYT correction you make is working directly on this tissue. The clinical results you see afterward are not coincidental findings. They are mechanistically predictable once you understand what this tissue is actually connected to.

Two Signals, Multiple Destinations

Inside each muscle spindle, intrafusal fibers are innervated by two types of afferent neurons. The Ia fibers wrap around the nuclear bag and chain fibers as primar

The Navicular Bone: A Keystone for Foot Mechanics and Whole-Body Health

Uncategorized Apr 14, 2023

What is the most remarkable human thing on the planet?

Is it our oversized brains for our bodies? Is it that we have terraformed the planet and our homes to be more hospitable for our furless bodies? Or is it the art, cities, and sciences our brains and society have created?
The most human thing on the planet is our feet and how it allows us to be bipedal. The anatomy that makes that possible is our straight big toe and our 3 arches of the foot, of which the navicular bone is the keystone of the medial arch.

The navicular bone, a small yet significant component of the human foot, plays a crucial role in foot mechanics and overall body health. This unique bone, nestled within the medial longitudinal arch, has been instrumental in developing human bipedalism - one of our most distinguishing traits as a species.

Bipedalism relies heavily on the structural adaptations of our feet, which are markedly different from those of our closest relatives, the great apes. While ape feet are charac...

The 1% Rule and How Marginal Daily Gains Will Change Your Life

Uncategorized Apr 12, 2023

 

"Most people overestimate what they can do in a day and underestimate what they can do in a month. We overestimate what we can do in a year and underestimate what we can accomplish in a decade." ~Mathew Kelly "The Long View."

As healthcare professionals, it is essential to prioritize personal growth to provide better patient care; that should be our primary focus in business. Our patients may not be coming to us consciously because they seek a life change or a spiritual awakening. But that may be what they need to heal from the physical maladies that brought them into our office.

I have learned over the years that if you aren't walking your talk, meaning that if you aren't trying to improve your life, then your patients would put forth the effort to heal themselves. And this translates to that if you aren't getting off your ass, you will have to work that much harder to get your patients off their ass to make your job easier!

For me, this really becomes that I don't give a damn...

Weekly Focus - K27 / Neurological Disorganization

Uncategorized Mar 03, 2019

 

Neurological Disorganization: (part one)

Definition

Many times, a patient will show indications of specific muscular weakness, TS line, postural sign, etc. However, on testing, the weakness is found on the opposite side of the body. This condition is termed switching. 

This is possibly one of the most important topics we will cover here in this course.  Most of the patients that you will see in your practice are switched.  If a patient is not switched, then they are less likely to hurt themselves, others, or the environment intentionally.  These things are not logical events and detrimental to life.  Vithoulkas states, “As with all things, the human organism was originally designed to function harmoniously and compatible in the environment… Any imbalance inevitably leads to destruction, which diminishes both the human being and the universe in which he or she lives… Ideally, the human race should have enough consciousness and awareness to live within and contribute to the order...

Weekly Focus - Category II

Uncategorized Feb 24, 2019

Category II/ Heel Lifts

Dr. Dejarnette classified three different types of sacroiliac problems.  The Category II is a bony misalignment between the ilium and sacrum.  Dr. Dejarnette was a contemporary of Dr. Goodheart Sr., and this led Dr. Goodheart Jr. to be very interested in the SOT Categories.  The Category II lesion may be corrected with an osseous adjustment or blocking procedure.

Indications:

  • The patient may have lateral sway
  • Can be associated with a spheno-basilar fault

Therapy Localization:

  • With the patient in a supine position, the patient contacts first one sacroiliac joint and then the other and a strong muscle is tested for weakening (one hand to one joint)
  • In SOT technique, they talk about the arm fossa test.  This is a test of a straight arm and therapy localization to the inguinal ligament,
    • The upper portion (fossa) of the ligament (by the ASIS)
    • The lower part (fossa) of the ligament (by the pubic bone)
  • PI ilium
    • Will show tenderness at the i...
