• The Purpose of the AdjustmentThe purpose of a Nucca adjustment is to restore the spine to its normal biomechanical balance and to bring all structures back to vertical axis.

It is the understanding on how to direct a calculated force from the atlas down through resistance and allow the spine to correct to zero.

To measure the subluxation and measure the effects of the adjustment.

• Four Components Of BiomechanicsMeasure where it isVisualize the path that the BODY has broken down inDeliver a force to a specific point of application to overcome resistanceKnow what to do if it doesnt correct

• Key WordsVectorResistanceForceReduction PathwayPoint of ApplicationClosed Kinetic ChainCorrection

• More Breakdown of TerminologyVertical Axis- Gravity with relation to the bodyAPL- Atlas Plane LineAngular Rotation- the direction in the frontal plane of the cervical spineCentral Skull Line-The bisecting line through the patients skull that is the midpoint of the skullCSLAPLAngular Rotation

• What do we learn from this model?We learn two things: the precise vector or line of drive and the point of application.

The precision of the calculated vector is what cause the resistances to breakdown with little application of force.

The correct point of application will create a correct position.

• To summarizeIf an adjusting force fails to overcome the resistances in a C1 sublux., it fails to be corrective.

The adjusting force must be directed exactly along a resultant that counteracts the resistances, doing this correctly greatly reduces the depth and force that is needed.

If the adjusting force is greater than the resistances than a greater misalignment can result, if to small then the misalignments are not sufficiently corrected.

• How is this accomplished A unique ModelThe skull and lower cervical spine function as if on the rim of a circle.This is important to understand what we are trying to accomplish when we make the adjustment.We call this C/A the point at which the skull and lower angle move at the different speeds, but the same distance.

• Putting it all togetherFrom a breakdown of the whole bodyWe calculate a vector Than by applying a force at one point At a specific point of application Through a closed kinetic chainDown the reduction pathwayTo overcome resistanceAnd correct the misaligned spine

• Patterns of mis-alignmentThrough clinical experience Dr. Gregory found that people misalign in certain patterns. We call these the Basic Types.

There are Basic types and out of pattern types which are similar in there basic components but have structures moving in opposing and out of sequence patterns.

• The Basic TypesThe basic types are:

Basic type 1

Basic Type 2

Basic Type 3

Basic Type 4

• But before we learn that.Headpiece placement The position of the headpiece is critical in order to gain an optimal correction.

Remember the Point of application?

The headpiece helps facilitate the adjustment because it is fixed and stabilized during the adjustment, so that the adjustors corrective force can be controlled.

• Headpiece OverviewThe headpiece is divided into four areas: A, B, C, D

• Headpiece OverviewWe position the head according to the type of misalignment.

The more the skull is vertical the more support it needs during the adjustment so that it does not move.

A skull that is leaning away from the VA or towards the VA will be positioned differently in order to get the correction.

• Other Factors:In the basic type 1 as with other types:We need to visualize the skull and spine down to the pelvis as a three dimensional structure that responds and misaligns three dimensionally.The short leg and weight bearing should be on the same side in a basic misalignment.This forms a single reduction pathway.

• AgainWhere do we brace?

• Type 2For a type 2 you could brace on C or you could brace on D.Another thing to look at is the body position.If there is a lot of rotation you can position the shoulders on the table differently to help reduce this factor of the misalignment.

• AgainWhere to brace?

• Type 4In a type 4 we have to see what percentage of the misalignment is head tilt and what percentage is angular rotation.

If there is more head tilt then we have to place the mastoid support more below the skulls center of gravity.

If we have more angular rotation then we have to brace the skull closer to the center of gravity to take out the angular rotation.

• Practice ExamplesWhat is this type?

How do we correct it?Type 4 Head Piece on (C) or (D)

• What is the type?

How do you correct it?Type 3 Head Piece on (D) or (C)

• What is it and how would you correct it?Type 1 Head Piece on (B) or (A)

• Finally, what would this one be and what is the solution?Type 2 Head Piece on (D)

• Final OutcomeTo restore the BODY to anatomical zero and OPTOMIZE a patients ability to HOLD a correction and Heal at the highest possible rate.PelvisLevel & non-rotated pelvisBody center on vertical axisLevel atlas & base of supportSkull on the vertical axisDigital scales within 2% of body weight

• ConclusionBetter than 90 percent of the energy output of the brain is used in relating the physical body in its gravitational field. The more mechanically distorted a person is, the less energy for thinking, metabolism and energy.Roger Sperry, Nobel Prize Winner, Brain Research
