etiology: birth, genetic
axis: two transverse axis
diagnoses: named for the position of the SBS (flexed or extended)

extension motion

Front 6

what does an extension strain pattern cause?

Back 6

depressed SBS

Transverse diameter decrease
motion preference is extension/ internal rotation
sacrum nutated

Front 7

what motion, while present, is diminished in an extension strain pattern?

Back 7

flexion

Front 8

what would an observational diagnosis of a flexion strain pattern include?

Back 8

face round, wide side to side, short from above down
orbits widened diagonal diameter, eyes protruded
ears protruding
palate wide and flat

Front 9

what would an observational diagnosis of a extension strain pattern include?

Back 9

face oval, narrow side to side, long from above down.
orbits narrow diagonal diameter, eyes retruded
ears close to head
palate narrow and high

Front 10

what would you feel on the classic vault hold w/ a flexion strain pattern?

Back 10

fingers on the greater wings of the sphenoid and lateral angles of the occiput are symmetrically widened and somewhat inferior.

Front 11

what would you feel beneath your fingers in the classical vault hold during an extension strain pattern?

Back 11

fingers on the greater wings of the sphenoid and lateral angles of the occiput are symmetrically narrowed and somewhat superior

Front 12

what are the etiologies of tosion?

Back 12

birth, trauma, typically at an angle to one quadrant of the head.

Front 13

a blow in the anterior quadrant would affect what two bones?

Back 13

frontal and zygoma

Front 14

a blow in the posterior quadrant would affect what two bones?

Back 14

parietal or occipital

Front 15

what is the axis for torsion?

Back 15

anterior-posterior axis from nasion to opisthion

Front 16

what two bones at the SBS rotate in opposite directions?

Back 16

sphenoid and occiput

Front 17

how do you name the side of torsion?

Back 17

named for the side of the superior (high) greater wing of the sphenoid bone

Front 18

Using the vault hold, what would your left and right hand experience in a left torsion?

Back 18

left hand: index finger is superior (rotates towards you); little finger is inferior (rotates away from you)
right hand: opposite of the left

Front 19

Using the vault hold, what would your left and right hand experience in a right torsion?

Back 19

Left hand: opposite of the right
right hand: index finger is superior (rotates towards you); little finger is inferior (rotates away from you)

Front 20

what is the etiology of Side bending/ rotation?

Back 20

trauma

blow to left side--> right side bending rotation strain
opposite for right

Front 21

what are the axes of sidebending/ rotation? which way do the sphenoid and occiput rotate in each axis?

Back 21

Vertical axes: 2 parallel
one through the center of the sphenoid
one through the foramen magnum
sphenoid and occiput rotate in opposite directions
one A-P axis:
opisthion (occipital bone at birth) to nasion (rotation)
sphenoid and occiput rotate in the same direction

Front 22

how do you diagnose side bending/ rotation?

Back 22

named for the side of the convexity of the SBS

Front 23

what would you feel in the vault hold for a left SBR?

Back 23

left index and little fingers spread apart and move inferior (away from you)

right index and little fingers come together and move superior (toward you)

Front 24

what would you feel in the vault hold for a right SBR?

Back 24

left index and little fingers come together and move superior

right index and little fingers spread apart and move inferior

Front 25

what is the etiology of lateral strain?

Back 25

trauma to one side of the head anterior or posterior to the SBS, or birth or from compression in utero

Front 26

what are the axis for lateral strain? what other strain pattern has 2 similar axes?

Back 26

2 parallel vertical axes:
1) thru base of the sphenoid
2) one thru the foramen magnum

sidebending has those axis + additional A-P axis.

Front 27

how do you diagnose a lateral strain?

Back 27

direction of the base of the sphenoid

Front 28

what are the palpatory findings of a left lateral strain in the vault hold?

Back 28

index fingers shift laterally to the right and the little fingers shift to the left

Front 29

what are the palpatory findings of a right lateral strain in the vault hold?

Back 29

index fingers shift laterally to the left and the little fingers shift to the right

Front 30

what is the lateral strain clinical correlation?

Back 30

plagiocephaly--> parallelogram shaped head

Front 31

what is a vertical strain usually secondary too?

Back 31

trauma

Front 32

what are the two axes of vertical strain?

Back 32

two parallel transverse:
- one thru the sphenoid
- one thru the occiput

Front 33

how do you name the diagnosis for vertical strain?

Back 33

named for the direction the posterior surface of the body of the sphenoid has shifted (superior or inferior).

Front 34

what direction do the sphenoid and occiput rotate in for vertical strain?

Back 34

same direction--> one in flexion and the other in extension

Front 35

what palpatory findings would you find on a vault hold of a superior vertical strain?

Back 35

index fingers rotate inferior and little fingers rotate superior

Front 36

what palpatory findings would you find in a vault hold of an inferior vertical strain?

Back 36

index fingers rotate superior and little fingers rotate inferior

Front 37

pt presents with a hx of concussion, presenting with headache, low energy and a short attention span.. what should be highest on your list for strain pattern? what else would add more evidence to this differential?

Back 37

SBS compression

- hx of head trauma, difficult labor (FORCEPS), pt w/ difficulty concentrating and sluggish thinking.

Front 38

what two instances should you suspect cranial strains?

Back 38

trauma and difficulty during birth
