The Initiating Event

Injury caused Spinal Displacement Subluxation

All spinal displacement problems had to have a beginning. By performing digital analysis of static and motion x-rays on thousands of patients, the author and his associates were able to demonstrate that sudden applied forces, (faster than 0.3 seconds, muscles reaction time) produce what they call “initiating event displacement-subluxations”, otherwise called whiplash injuries of the head, neck and spine.

The “initiating event displacement-subluxation” begins when the skull on C-1 vertebral joint is injured and the skull cannot flex or extend. Normal skull flexion-extension is 15 degrees each way for a total of 30 degrees of total flexion-extension movement on the first cervical vertebrae.

Kapandji, I. A. states, when the skull is locked out of flexion or extension on the atlas, C-1 vertebrae, abnormal sagittal (from the side) and A-P (front to back) positions and motions are forced to be altered. The head is forced into “forward head posture” when displaced and locked in either flexion or extension. When locked in partial or complete extension, stress leverage (intensity of loading) is forced on the lower cervical spine which then forces it to over flex backward and to function backward. This aberrant flexion motion further forces the head forward relative to the body with a partial or complete loss of the cervical lordotic (forward) curve. That same motion causes the lower cervical and upper-thoracic spine to move into a backward kyphotic displacement, also causing up to 30% of elongation traction pull on the spinal cord and brain stem.

When the skull is locked in partial or complete forward flexion on the first vertebrae C1, the neck is forced backward into Kyphosis, forcing an “S” curve in the sagittal (side view) X-ray that appears in the PDF.

Loss of normal sagittal spinal position causes a loss of spinal function necessary for oxygen and nutrition delivery as well as metabolic waste elimination of the involved tissues. A stenosis (narrowing of the spinal canal) is produced. Local inflammation, pathologies of hard and soft tissues results in chronic pain.

In addition to the chronic pain, nerves exiting the involved spinal areas are also adversely affected with disruption of their information delivery system, especially C3-C5 vertebrae and the phrenic nerve that controls the diaphragm muscle and breathing. This also causes
dis-harmony, dis-function and dis-ease in those distant organs and parts supplied by the affected nerves. (See PDF for autonomic nervous system chart.)

The skull and spine form a closed kinetic system, that is, the parts balance (compensate) each other to align with gravity and keep the skull aligned upright under gravity. EXPLANATION: If one part displaces backward another part is forced to displace forward. If one part displaces sideways, another part has to displace to the opposite side. One can now understand and conclude that form and function of the (sagittal) neck and front to back (A-P) lower thoracic spine and pelvic girdle cannot be corrected and/or stay corrected until the “Initiating event subluxations” including head forward posture and cervical lordosis have first been corrected.

In the Pre X-ray seen in the PDF you will notice that the resting skull measures displaced in extension 5° on the atlas vertebrae (the initiating event).

The skull on atlas and lower sagittal cervical spine correction is caused by the patented Pettibon frontal head weighting neuromuscular stimulation rehabilitation. This process causes the person’s own muscles to contract and relax as needed thereby restoring the normal sagittal position of the initiation event, skull on C-1 vertebrae and the lower neck. NOTE: The head weighting procedures will be explained later in this series of articles.

The series of x-rays below show the skull displaced in extension on atlas and the lower neck is displaced backward into kyphosis. In this series of correction procedures, 5 pounds of weight on the front of the head weight was worn in a harness for 20 minutes twice per day. The two interim x-rays demonstrate that the procedures are gradually producing results. The post x-ray taken after 4 weeks of neuromuscular stimulation show that the person’s own muscles have corrected the skull on C-1 vertebrae displacement as well as caused the lower neck to regain its normal forward curve and the front of the curve to re-align normally under gravity.
