Cranial II

Question 1

Cranial Rhythmic Impluse (CRI) is driven by the Primary Respiratory Mechanism (RPM). What does this mean?

Answer 1

There is a cyclic movement of the cranium, sacrum and body thought to be an inherit motility of the brain.

Question 2

How many cycles per minute are CRIs

Answer 2

6-10 cycles/minute

Question 3

What is the Traub-Hering Mayer theory?

Answer 3

Slow fluctuations in blood flow parameters of cortex.

Question 4

According to Heisey and Adams: in a cat model, how many microns of lateral movement are there at the sagittal suture?

Answer 4

30-70 microns

Question 5

According to Heisey and Adams: in a cat model, how many microns of lateral movement are there at the parietal suture?

Answer 5

250 microns

Question 6

According to early data on CRI, are changes symmetrical?

Answer 6

NO. not symmetrical (this makes sense because the body isn’t symmetrical)

Question 7

[TQ} According to a study, at what level (in microns) are 100% of people able to detect movements?

Answer 7

45 microns

Question 8

When you just do use active motion testing of the SBS (not putting motion into the system), does it mean change anything?

Answer 8

Yes. it still changes. Sandhouse did a study in it (so it’s probably important)
