1.7.15 - Cranial Strain Patterns

Question 1

torsion

Answer 1

right or left

Question 2

sidebending rotation

Answer 2

right or left

Question 3

vertical strain

Answer 3

superior or inferior

Question 4

lateral strain

Answer 4

left or right

Question 5

SBS compression

Answer 5

also cranial strain pattern

Question 6

torsion

Answer 6

sphenoid and occiput rotate opposite direction

AP axis

named by superior greater wing of sphenoid**

Question 7

left index finger moves superior and 5th digit moves inferior

Answer 7

left torsion

Question 8

vault hold

Answer 8

index - greater wing of sphenoid

5th digit on lateral angles of occiput

Question 9

sidebending rotation

Answer 9

sphenoid and occiput rotate opposite direction around parallel vertical axis to side bend

and bones rotate around AP axis in same direction

side of SBS convexity - cranium moves inferiorly

Question 10

naming of sidebending rotation

Answer 10

named by side of SBS convexity and side that moves inferiorly

Question 11

SBS convexity

Answer 11

cranium moves inferior on side of SBS convexity in sidebending rotation

Question 12

fingers left hand spread apart and move inferior and fingers right hand come together and go superior

Answer 12

left sidebending rotation

Question 13

vertical strain

Answer 13

sphenoid and occiput rotate same direction about parallel axes (flex/extend)

shearing force at SBS

one bone in flexion and one in extension

Question 14

naming of vertical strain

Answer 14

direction of base of sphenoid

Question 15

index fingers both hands move inferiorly and 5th digits both hands move superiorly

Answer 15

sphenoid base moving superiorly

-superior vertical strain

Question 16

lateral strain

Answer 16

sphenoid and occiput rotate same direction about parallel vertical axes

shearing force at SBS

Question 17

naming of lateral strain

Answer 17

direction the basisphenoid moves

Question 18

index fingers shift to right

5th digits shift to left

Answer 18

left lateral strain

sphenoid base turning left

occipital base turns right

Question 19

SBS compression

Answer 19

approximation of sphenoid and occipital base that compress along AP axis

Question 20

fingers of both hands approximate

head feels hard and limited im movement

Answer 20

SBS compression

Question 21

decreased primary respiratory rate

Answer 21

with SBS compression

Question 22

force applied centrally over anterior/superior frontal bone

Answer 22

superior vertical strain

Question 23

force to superior occiput and directed superior to anterior

Answer 23

superior vertical strain

Question 24

caudal force to basisphenoid - from bregma

Answer 24

inferior vertical strain

Question 25

landing on buttocks

Answer 25

inferior vertical strain

Question 26

caudal force along posterior sagittal suture

Answer 26

inferior vertical strain

Question 27

force at nasion or opisthion

Answer 27

SBS compression

Question 28

lateral to medial force over greater wing of sphenoid

Answer 28

lateral strain

Question 29

lateral force applied over occiput pushing posterior aspect of occipout

Answer 29

lateral strain

Question 30

force to mandible

Answer 30

external rotation of temporal bone

Question 31

traction of one side of mandible due to dental work

Answer 31

internal rotation on ipsilateral side
