During inhalation, the sacral base will move ______
Posterior
During exhalation, the sacral base will move _______
Anterior
Inherent (craniosacral) motion occurs about the _______ axis
superior transverse
During craniosacral flexion, the sacral base rotates _______
posteriorly (counter nutates)
During craniosacral extension, the sacral base rotates ______
anteriorly (nutates)
,Nutation = nod forward
postural motion occurs around what axis
middle transverse axis of the sacrum
Bending forward causes the sacral base to move _______
anteriorly
Dynamic motion occurs during _______
ambulation

How to tell if there is an innominate dysfunction
A positive standing flexion test on the side of dysfunction
What occurs in an anterior innominate rotation
One innominate will rotate anteriorly compared to the other. Rotation occurs about the
inferior transverse axis of the sacrum
What are the findings of an anterior innominate rotation?
- tight quads
- ASIS more inferior on one side
- PSIS more superior on one side
- Positive standing flexion test
- Positive ASIS compression test
What occurs in a posterior innominate rotation?
One innominate will rotate posteriorly compared to the other. Rotation occurs about
the inferior transverse axis of the sacrum
What are the findings of a posterior innominate rotation?
-tight hamstrings
- ASIS more superior on one side
- PSIS more inferior on one side
, - Positive standing flexion test
- ASIS restricted in compression
What occurs in a superior innominate shear?
One innominate will slip superiorly compared to the other
What are the findings of a superior innominate shear?
- ASIS and PSIS are both more superior on one side
- Pubic rami more superior ipsilaterally
- Shorter leg ipsilaterally
- Positive standing flexion test
- Positive ASIS compression
What occurs in an inferior innominate shear?
One innominate will slip inferiorly compared to the other
What are the findings of an inferior innominate shear?
- ASIS and PSIS both more inferior ipsilaterally
- pubic rami more inferior ipsilaterally
- Longer leg ipsilaterally
- Positive standing flexion test
- Positive ASIS compression test
What occurs in a superior pubic shear
One pubic bone is displaced superiorly compared to the other.
What are the findings of a superior pubic shear?
- ASIS and PSIS appears to be leveled
- Pubic bone is superior ipsilaterally
- Positive standing flexion test
- Positive ASIS compression test
What occurs in an inferior pubic shear?
One pubic bone is displaced inferiorly compared to the other
