Sacral flexion (nutation)

Question 3

Cranial SBS Dysfunction:

Torsion

Answer 3

Rotate is opposite directions around 1 AP axis.

Question 4

Cranial SBS Dysfunction:

Sidebending/Rotation

Answer 4

Rotate in the same direction about an AP axis and rotate in opposite direction around 2 vertical axis

Question 5

Cranial SBS Dysfunction:

Lateral Strain

Answer 5

Rotate same direction around 2 parallel vertical axis

Question 6

Cranial SBS Dysfunction:

Vertical Shear

Answer 6

Rotate in the same direction about their transverse axis

Question 7

SBS Flexion - Skull ??

Answer 7

Skull widens laterally

Shortens AP diameter

Question 8

SBS Extension - Skull??

Answer 8

Skull narrows laterally

Lengthens AP diameter

Question 9

Cranial: Palpatory

Flexion

Answer 9

Paired bones move into external rotation (don’t think extension)
Wrists flex

Question 10

Cranial: Palpatory

Extension

Answer 10

Paired bones move into internal rotation

Wrists extend

Question 11

Cranial: Palpatory

Torsion

Answer 11

Hands rotate in opposite directions; Torsion named for higher sphenoid

Question 12

Cranial: Palpatory

SB/Rotation

Answer 12

Fingers on concave side appear closer together. Fingers of convex side are wider and inferior.

Question 13

Cranial: Palpatory

Lateral Strain

Answer 13

Parralelogram; little fingers move laterally and point to side of lateral strain

Question 14

Cranial: Palpatory
Vertical shear (superior/inferior)

Answer 14

Superior - hands rotate anteriorly; wrists are superior

Inferior - hands rotate posterioly; wrists are inferior
