2. Intro to Fryett's spinal Mechanics

Question 1

What is it called when a vertebrae gets “stuck” in rotation and sidebending? (general term)

Answer 1

Example of somatic dysfunction.

this would be described as “pathologic”

Question 2

Motion at a vertebra refers to the position of the _____A__ vertebra in relation to the vertebra directly ____B____

Answer 2

A. superior

B. inferior

Ex. T3 on T4

Question 3

Which column is the “load bearer” and which “guides and limits motion”?

Anterior column or posterior column?

Answer 3

Anterior= load bearing (vertebral bodies, discs, ALSL, PLSL)

posterior= Guider and motion limiter ( pedicles, TP, lamina, SP, arches, facet joints, intervertebral foramen)

Question 4

What kind of joints are zygopophyseal joints?

Answer 4

True synovial

Question 5

What determines the overall movement of the vertebral unit?

Answer 5

Facet joint orientation

Question 6

Movement beyond ____A___ engages the facet joints

Answer 6

Neutral

Question 7

For which part of the vertebral body do you name the motion?

Answer 7

the most anterior and superior aspect.

Ex. right rotation- anterior/superior edge moves right. Which way does spinous process go?

Question 8

In which plane and about which axis do the following motions occur?
Rotation, sidebending, flexion, extension?

Answer 8

Rotation- transverse plane, vertical axis
Sidebending- coronal, AP axis
flexion/extension- saggital plane, transverse axis

Question 9

which side will the paraspinal muscle be fuller during a right rotated vertebra?

Answer 9

fuller on the RIGHT side.

Question 10

Sidebending on left will cause a CLOSED facet joint on which side?

Answer 10

Closed on the left

Open on the right.

Question 11

In neutral range where does most of the weight of the body lay?

Answer 11

On the vertebral bodies and discs.

Question 12

Are the facet joints opened or closed in neutral range?

Answer 12

Neutral does not cause the facet joints to be engaged (open or close)

Question 13

Non-neutral, when are facet joints open and when are they closed?

Answer 13

open during flexion

Closed during extension.

Question 14

Fryette’s spinal mechanics I

Answer 14

1. In the neutral range, side bending and rotation are coupled in opposite directions.

When side bending a GROUP will rotate to opposite side

applies only to thoracic and lumbar vertebrae

Question 15

Fryette’s II

Answer 15

in sufficient flexion or extension, sidebending and rotation are coupled in the SAME direction

When side bending ONE will rotate to the same side.

Applies to thoracic and lumbar

Question 16

Fryette’s III

Answer 16

Initiating movement of a joint in any plane of motion will modify the movement of that joint in all other planes of motion. (applies to all joints of the body)

Question 17

Why do things become stuck?

Answer 17

could be trauma, posture, postural compensation (short leg), viscerosomatic reflex, pathology (genetic, degenerative)

Question 18

What is somatic dysfunction?

Answer 18

impaired or altered function of the related somatic system including skeletal, arthrodial, myofascial structures and related vascular, lymphatic and neural elements.

Question 19

For something stuck in the right rotation, the transverse process is ____A___ on the right. motion testing will be restricted when pushed ____B____

Answer 19

A. posterior

B. Anterior

Question 20

Motion testing: when testing a vertebrae stuck sidebent left, it can be freely translated for the ___A__ to the ___B___.

Answer 20

a. Left

B. Right

Question 21

Type I is associate with _____ paraspinal muscles.

Chronic or acute?

Answer 21

long

Chronic, may be related to postural compensations

Question 22

True or false: a type one group somatic dysfunction could be related to a type II at the apex or the superior/inferior end of the curve

Answer 22

True.

Question 23

Type II is associated with ______ paraspinal muscles.

Answer 23

short

Question 24

Type II somatic dysfunction: flexed

flexed segment rotates ___A___ from the open facet joint and ____B____ the closed facet joint, and returns o symmetry when placed in ___C___

Answer 24

A. away

B. toward

C. flexion

Question 25

Type II: extended

Extended segment rotates ___A___ and sidebends __B__ from the open facet joint and ___C___ the closed facet joint, and returns to symmetry when placed in ___D___

Answer 25

A. Away

B. Away

C. toward

D. Extension

Question 26

Name it.

T5 transverse process is posterior on the right, easily translated (from the right) to the left and there is ease of movement when the patient bends forward

Answer 26

T5 flexed rotated right sideband right

T5 F RSr
