Front 1

What are the 3 planes of motion?

Back 1

Sagittal (like parting you hair)
Coronal (like wearing a headband)
Transverse (like wearing a belt)

Front 2

What are Fryette's Laws?

Back 2

physiological principles of spinal motion

Front 3

Fryettes Law 1; Type 1 mechanics

Back 3

when the thoracic and lumbar spine are in neutral (easy normal) position, the coupled motions of side-bending and rotation for a group of vertebrae occur in opposite directions (with rotation occuring toward the convexity)

Front 4

Fryettes Law 2; Type 2 Mechanics

Back 4

when the thoracic or lumbar spine is sufficiently flexed or extended, the coupled motions of sidebending and rotation occur in the same direction; motion occurs in a single vertebral unit where the forces are localized

Front 5

Fryettes Law 3;

Back 5

initiating motion of a vertebral segment in any plan of motion will modify the movement of that segment in other planes of motion; flexion, extension, side-bending to confirm SD

Front 6

the direction it will go easily

Back 6

somatic dysfunction

Front 7

the direction it wont go easily

Back 7

restriction

Front 8

Posterior surface of joint capsule is taut.
Facets are engaged in open position.

Back 8

flexion

Front 9

Anterior surface of the joint capsule is taut.
Facets engaged in the closed position.

Back 9

extension

Front 10

No stress on the joint capsule.

Back 10

neutral

Front 11

steps to diagnose a type 1 SD

Back 11

1. Name the involved spinal segments (remember it’s a group of vertebra, more than one segment)
for example: L1-L3 or L1-3
2. Name the sagittal plane involved (neutral)
abbreviated: N
3. Name the direction of side-bending
for example: side-bent left, written S(L)
4. Name the direction of rotation
for example: rotated right, written R(R)
Putting it all together: L1-3 NS(L)R(R)
All of these components must be present in naming!

Front 12

prevents from opening, exaggerated in flexion, normal in extension

Back 12

locked closed

Front 13

remains opended, exaggerated in extension, normal in flexion

Back 13

locked open

Front 14

naming non neurtal type 2 SD's

Back 14

Name the involved segment (single vertebra) where you feel the rotation (or TART). For example: L1
Test the spine in flexion and extension and see where the rotation/lump disappears. This is the position of ease. For example: flexion, written F
Then name the direction of the rotation, for example: rotated right, written R(R)
Finally, name the direction of sidebending, for example: sidebent right, written S(R)

Putting it all together: L1FR(R)S(R) or L1FRS(R)
All of these components must be present!

Front 15

determines the limit of physiological range of motion at that segment.

Back 15

The articular capsule that surrounds the zygoapophyseal joint (facet)

Front 16

Two adjacent vertebrae with their associated intervertebral disk, arthorodial, ligamentous, muscular, vascular, lymphatic and neural elements.

Back 16

vertebral unit

Front 17

T1-3:

Back 17

TP directly lateral to SP.

Front 18

T4-6

Back 18

TP halfway between SP and that of segment above.

Front 19

T6-9

Back 19

TP directly lateral to spinous process of segment above.

Front 20

T10-12

Back 20

TP return directly to lateral spinous process.
