“Level Disc Theory” The optimal relationship between two bones is when they are level on the A-P and on the Lateral. This promotes range of motion on all planes. In the lumbar spine the lordosis is primarily made up of the heights of the vertebral bodies. The disc makes up about 5% of the lumbar lordosis

The Disc Four concentric layers of the intervertebral disc: (1) an outer anulus fibrosus, (2) a fibrocartilaginous inner anulus fibrosus, (3) a transition zone and (4) the central nucleus pulposus.

The “Subluxation” A spinal fixation occurs when the normal shock absorption of the spine creates extension micro-trauma . (walking, talking and moving all day) This creates convergence of the endplates in the back of the FSU Cross fiber adhesions (a.k.a. cross collagen linkages) occur in the annular fibers causing fixation Fixation creates a build-up of interstitial fluid around the IVF which puts pressure on the spinal nerves (and other physiologic consequences) Pressure on the nerves creates altered physiological function resulting in SUBLUXATION SUBLUXATION .

Instrumentation The instrument is run at a rate of about 2 seconds per segment from: T1- C1 then C7- Sacrum The instrument can only read 1.8mm to 5mm below the surface of the skin

Digital Palpation Feeling for the “Pit of Edema” This is a build-up of Interstitial fluid over the facet joints . It occurs when there is Loss of Motion. It can also be from Trophic Changes (connective tissue breakdown) This leads to lack of imbibition It is said to feel like a “bruise on an apple”

Instrumentation J Manipulative Physiol Ther 1991 Jul-Aug;14(6):361-7 The inter- and intraexaminer reliability of a paraspinal skin temperature differential instrument. Plaugher G, Lopes MA, Melch PE, Cremata EE. An experiment was undertaken to determine the intra- and interexaminer reliability of a paraspinal skin temperature differential instrument. Nineteen pain-free female chiropractic college students participated as subjects for the investigation. Three separate areas of the spine (C4-T2, T4-T8 and L2-L5) were examined for concordance between two examiners. Additionally, intraexaminer reliability was tested by having each examiner repeat the
