What does RRADS for CRI stand for?

Answer 1

Rate
Rhythm
Amplitude
Direction
Strength

Question 2

If your index fingers move inferior and pinkies superior, what strain pattern?

Answer 2

Superior vertical strain

Pt looking down

Question 3

If your index fingers move superior and pinkies inferior, what strain pattern?

Answer 3

Inferior Vertical strain

Pt looking up

Question 4

If your right hand moves anteriorly and the left hand moves posterior, what type of strain?

Answer 4

Right Torsion

-named for Greater Wing of Sphenoid

Question 5

If your left hand move anteriorly and right hand move posteriorly, what type of strain?

Answer 5

Left Torsion

-Named for greater wing of sphenoid

Question 6

if your index fingers tip right, and your pinkies tip left, what type of strain?

Answer 6

Left Lateral

-named for SBS base

Question 7

If your index fingers tip left and your pinkies tip right, what type of strain?

Answer 7

Right Lateral

-named for SBS base

Question 8

If your right hand spreads farther apart and your left hand comes together, what torsion?

Answer 8

Right SBS sidebending rotation

-named for fuller side

Question 9

If your left hand spreads farther apart and your right hand comes together, what torsion?

Answer 9

Left SBS sidebending rotation

-Named for fuller side

Question 10

What are the three contacts for palpation of the head?

Answer 10

Vault Contact
Becker Contact
Fronto-occipital contact

Question 11

Describe Vault Contact finger positions

Answer 11

1. Index fingers on greater wing
2. Middle fingers anterior to ear
3. Ring fingers on mastoids
4. Pinky far back on occiput
5. Palms on parietals
6. Thumbs contact the frontal

Question 12

Fronto-occipito contact hand position

Answer 12

Posterior contact cradling patients occiput

Anterior contact:

• thumb pad on one greater wing
• Index finger or middle on other greater wing
• Palm on forehead or frontal bone

Question 13

Becker contact hand positions

Answer 13

1. Thumbs rest on greater sphenoid wings
2. Index fingers on mastoid
3. Middle to pinky fingers rest on occiput
4. Palms cup the occiput

Question 14

In SBS flexion, which way does sacrum move?

Answer 14

Counternutition

• Base tips posterior
• Apex moves anterior

Question 15

In SBS extension, which way does sacrum move?

Answer 15

Nutition (towards nuts)

• Base moves anterior
• Apex moves posterior

Question 16

SBS Flexion is paired with what respiratory motion?

Answer 16

Inspiration and “FL”external rotation

Question 17

SBS Extension is paired with what respiratory motion?

Answer 17

Exhalation paired with Expiration and Internal Rotation

Question 18

Describe Steps in Balanced Membranous Tension for Indirect Cranial Manipulation

Answer 18

1. Determine extent of ROM
2. Place SBS in midpoint of ROM using Cranial Contact
3. Maintain “neutral” position and CRI will dampen (This is called Still Point)
4. Maintain position and CRI will return to normal and feel more symmetric than before
