Lab 1: Intro to OCMM

Question 1

What is the hand position for the Becker Contact?

Thumbs, index, middle-pinky, and palms

Answer 1

1. Thumbs - rest on greater wing of sphenoid
2. Index - rest on the mastoid processes
3. Middle to pinky - rest on occiput w/ middle finger posterior to OM sututre
4. Palms - cup occiput and posterior aspect of parietals

Question 2

What is the correct setup for the Frontal Occipital Contact?

Answer 2

• One hand cups the occiput
• Long or little fingerof other hand on one greater wing of the sphenoid with thethumb on opposite greater wing
• Rest caudal elbow on table

Question 3

What are the coupled motions (flexion/extension) of the sphenoid and occiput seen with a superior vertical strain?

Answer 3

• Flexion at the sphenoid
• Extension at the occiput

*Both bones rotate about 2 transverse axes in the same direction

Question 4

During cranial flexion/extension the ethmoid mirrors the motion of?

Answer 4

Mirrors occiput motion

*Vowels move togther

Question 5

During cranial flexion/extension the vomer mirrors the motion of?

Answer 5

Mirrors sphenoid motion

*Sphenoid drives the Vomer

Question 6

What is the action of the vomer on the hard palate during SBS flexion?

Answer 6

Depresses the hard palate (aka flattens roof of mouth)

Question 7

Which direction do the greater wings of the sphenoid move during flexion?

Extesion?

Answer 7

• Flexion = anterior and inferior
• Extension = posterior and superior

Question 8

Which direction does the membranous portion of the Occiput move during flexion?

Extension?

Answer 8

• Flexion = posterior and inferior
• Extension = anterior and superior

Question 9

What is the normal rate of Cranial Rhythmic Impulse (CRI)?

Answer 9

10-14 cycles/min

Question 10

In healthy individuals the CRI is palpated as moving how?

Answer 10

Longitudinal and symmetric

Question 11

During Balanced Membranous Tension for the SBS, where is the SBS held and until when?

Answer 11

• Held in the midpoint of the available motion until a still point is obtained (still point = inability to feel CRI)
• Still point maintained until the CRI motion begins to return and is noted to be more symmetrical

Question 12

Which 2 cranial contacts (holds) can be used for Balanced Membranous Tension (Indirect)?

Answer 12

• Frontal occipital hold
• Vault hold
