FYI, subluxation in the upper cervical (UpC) segments: C-zero (occiput), C-1
> (atlas), and C-2 (axis) is different in as much as the segments'
> intervertebral surfaces are not symphyseal (discal) but instead are
> diarthrodial (synovial or disc-less and freely moveable).
>
> The vectors of structural displacement of individual vertebra from C-3
> inferiorly to L-5 over S-1 can be measured in a few vectors such as
> Anterior/Posterior, Inferior/Superior, Left/Right. Globally, vertebrae can
> be mesaured at the stress vertebrae of the 2 primary and 2 secondary spinal
> curves in Left/Right vectors in degrees. The Sacroiliacs can be measured as
> Interior/Exterior, Anterior/Posterior, and Inferior/Superior in millimeters.

> However, the mensuration of the UpC spine is considerably more complex and a
> single Reduction Pathway Vector for introduction of corrrective force must
> be ascertained and utilized in an alignment. Possibilities of mensuration
> findings of the 3 UpC segments runs into the thousands. Intense study over
> time is a necessary feature of UpC work.

> The amount of vectors and the magnitude of those vectors of measurable

> Special post grad lengthy training (usually years) and specialized

> a lever to align the whole cervical spine, the correction of same allows the
> "righting" system of the neural driven musculoskeletal system to right
> itself throughout the entire musculoskeletal system, often not only does it
> impact faults in the lower spine and pelvic, but also the extremities.

> a "tortuous and hazardous pathway" (F. Netter, M.D.; CIBA Collection). Not

> methods is a very gentle aplication of force to re-position the UpC
> segments.
>
> Formerly done by hand by all, now many UpC specialists are using large floor
> mounted alignment instruments to ease the difficult work of restoring to, or
> towards, zero the degrees and millimeters of the measured UpC subluxation
> complex.

> The UpC alignment in several of the UpC methods is performed within the
> Active Range of Motion and therefore there is no audible sound made or heard
> during the alignment process. The process may take 1 or more, but not many,
> attempts at any one alignment session. With the percussion force instruments
> the alignee cannot feel the alignment/adjustment procedure but should feel
> some or much immediate improvement in their palpatory exam, as indeed the
> alignor should observe objective improvements in the alignee pre to post
> exam.

> As a result of the negative impacts made on important neuronal (CNS) and

> improvement or complete restoration of function to distal targets subsequent
> to alignment/correction of the UpC subluxation complex often occurs without

> UpC subluxation is not found on X-ray but is ascertained by objective and
> subjective evaluation of the alignee. UpC subluxation (structural
> displacement) is measured on x-rays; 3 pre-adjustment to be exact in most
