1

Typical cervical vertebrae movement

Along the coronal plan

- Backward, Upward, Medial (BUM)

2

Typical thoracic vertebrae movement

Along the coronal plane

Backwards, Upwards, Lateral (BUL)

3

Typical Lumbar vertebrae movements

Along the sagittal plane

Backwards, medial (BM)

4

Reasons why ROM is limited

Thickness, elasticity and compressibility of discs

Shape and orientation of the zygapophysial joints

Tension in the articular capsules of facet joints

Resistance of back muscles and ligaments

5

Sagittal rotation movements

Flexion and extension

6

Coronal rotation movements

Sidebending left and right

7

Horizontal rotation movements

Rotation left and right

8

Transverse process specific to rotation

Rotated right:
-right transverse process will be posterior
- left transverse process will be anterior

Rotated left:
-right transverse process will be anterior
-left transverse process will be posterior

*rotation is respect to the vertebrae body movement*

9

Principle 1 characteristics

Generally refers to a group of vertebral segments (typically 3)

Rotation and side-bending are OPPOSITE
- sidebending occurs first
- rotation occurs along the side of convexity

No extreme flexion or extension

Causes discomfort but not pain and is usually chronic

Because sidebending occurs first, the nomenclature is N(sidebending)(rotation)

10

Principle 2 characteristics

Refers to single superior vertebral segment/ vertebral unit

Segmented vertebrae does not return to neutral and remains flexed or extended when the patient returns to neutral

Includes flexion or extension of the segmented
- induces same sidebending and rotation of the segment

Commonly causes a acute pain and short restrictor muscles are affected

Nomenclature goes (flexion/extension)(rotation)(sidebending)

11

Principle 3 characteristics

Initiating motion of a vertebral segment in any plane of motion will modify the movement of that segment in other planes of motion

*THERE IS NO TYPE 3 SOMATIC DYSFUNCTION*

12

Rules of 3 in thoracic spine

T1,2,3 and 12 =. Tip of each spinous process is at the same level as the transverse process of the same vertebrae

T 4,5,6 and 11 = tip of each spinous process is about 1/2 way between the transverse process of the same vertebrae and the one directly below

T7,8,9,10 = tip of each spinous process is at least one level below the same corresponding vertebrae and at the level of the vertebrae directly below it

13

Thoracic Spinous process special locations

T3 = scapular spine

T7 = inferior scapula angle

T12 = Twelfth rib

L4 = iliac crest

Xyphoid process = T9

Umbilicus = L3-L5

14

Cervical spine specifics

OA spinal segments
- named similar to type 1
- sidebending and rotation to opposite direction
- can be neutral, flexed or extended

AA spinal segments (C1/C2)
- only has rotational mechanics

C2-C7 spinal segments
- named similar to type 2
- rotation and sidebending occur to the same direction a
- can be neutral, flexed or extended

15

Flexion and extension plane and axis of motion

Sagittal plane and transverse axis

16

Motion of rotation along a plane and axis

Transverse plane

Vertical axis

17

Sidebbending along a plane and axis

Coronal/frontal plane

A-P axis

18

Tri-planar diagnosis upper thoracic spine

Tart 1st
- heat
- psuedomotor findings
- red reflex
- tissue abnormalities

Assess motion of the transverse processes (rotation first)
- determine any restriction of motion one way or the other first
- document the somatic dysfunction
- have the patient flex forward and extend to determine if the somatic dysfunction approves
- have the patient side bend and determine if the somatic dysfunction approves

Determine the somatic dysfunction in all 3 planes of motion and write the nomenclature
