Fryette's Mechanisms

Question 1

REQUIRED

Answer 1

page 100 of lab manual

Question 2

three cardinal motions?

Answer 2

rotation, sidebending, flexion/extension/neutral

Question 3

rotation

Answer 3

motion about a vertical axis in transverse plane

Question 4

sidebending

Answer 4

motion about an AP axis in coronal plane

Question 5

flexion/extension

Answer 5

motion about a transverse axis in sagittal plane

Question 6

neutral?

Answer 6

not single point
-but a range where weight of trunk is borne on vertebral bodies and discs

facets are not engaged**

Question 7

motion beyond neutral?

Answer 7

engages the facets

Question 8

fryettes principles

Answer 8

1 - in neutral range, sidebending and rotation are in opposite directions

2 - in sufficient flexion/extension, sidebending and rotation are in same direction

3 - initiating movement of vertebral segment in any plane of motion will modify movement of that segment in other planes

Question 9

1st and 2nd principles of fryettes?

Answer 9

only apply to thoracic and lumbar**

Question 10

in neutral position?

Answer 10

sidebending first, then rotation

-in opposite directions

Question 11

type 1 dysfunctions

Answer 11

tend to occur in groups, often compensating for a single type II dysfunction which is usually at apex or at either end of group curve`

Question 12

in non-neutral position?

Answer 12

**flexed or extended

rotation first, then sidebending
-in same direction

Question 13

type 2 dysfunctions

Answer 13

tend to occur alone, but two may be found adjacent to each other

extended type II SDs often result from segmental muscle contraction due to viscerosomatic reflex

Question 14

type II flexion somatic dysfunction

Answer 14

one facet gets stuck open

when this segment is extended or returned to neutral, one facet will remain open while the other closes

stuck-open facet is the pivot

this segment will rotate and sidebend toward the facet that closes

segment returns to symmetry in flexion

Question 15

type II extension somatic dysfunction

Answer 15

one facet unable to open (stuck closed)

when flexed or neutral one stuck closed

stuck-closed is pivot

rotation and sidebending will occur toward facet closed

segment returns to symmetry upon extension
-both close

Question 16

fryettes third principle?

Answer 16

all C, T, L vertebrae

motion in one plane, affects other two

Question 17

arthrodial restriction

Answer 17

joints

Question 18

muscular restriction

Answer 18

long paraspinal type I

short paraspinal type II

Question 19

fascial / ligament restriction

Answer 19

fibrosis, scarring, inflammation can shorten fascia

Question 20

edema

Answer 20

fluid distends, stretches, and restricts

Question 21

fryette notation

Answer 21

N neutral
F flexed
E extended
L left
R right
S sidebent
R rotated

type I - sidebending listed first
type II - rotation listed first

Question 22

how is SD named?

Answer 22

named for ease of motion of direction of freer motion

Question 23

motion restricted in ___?

Answer 23

SD is opposite to restriction

Question 24

“findings do not improve in flexion or extension?

Answer 24

must be stuck in neutral mechanics > type I

Question 25

paraspinal fullness?

Answer 25

group curve likely

Question 26

rule of 3s

Answer 26

tells you where you'll find the spinous process of thoracic vertebrae ``` 1-3: same level 4-6: half inch superior 7-9: inch superior 10: 1 inch 11: half inch superior 12: same level ```

Question 27

landmarks?

Answer 27

superior scap border - T2 scapular spine - T3 Scapular angle - T7 iliac crest - L4
