1
Q

Lateralization tests will tell you what about the axis of a torsion and unilaterally?

A
  • Positive test is opposite of the side of axis for a torsion
  • Positive test is on the same side for unilaterals
2
Q

What are the 2 active motion sacral tests?

A
  1. Backward Bending Test (Sphinx)
  2. Respiratory motion
3
Q

A neg. backward bending test indicates; while a positive indicates?

A

Neg. BBT = Flexed Sacrum

Pos. BBT = Extended Sacrum

4
Q

Dysfuntion along which axis will have bilateral findings; which sacral level?

A
  • Middle transverse axis (S2 anteriorly)
  • Postural Motion
5
Q

Innominate rotation occurs about which sacral axis; which sacral level?

A
  • Inferior Transverse Axis (S3)
6
Q

Dysfunctions along an oblique axis will have a deep sacral sulcus where in relation to the posterior/caudad ILA?

A

Opposite side

7
Q

Dysfunctions along a vertical axis will have a deep sacral sulcus where in relation to the posterior/caudad ILA?

A

On the same side

8
Q

Respiratory and craniosacral motion occur about which sacral axis at which sacral level?

A

Superior Transverse Axis (S2 posteriorly)

9
Q

How can you tell if a sacrum is unilaterally flexed vs. extended?

A
  • If deep sacral sulcus is on the right, posterior/caudad ILA on the right, lateralization test was on the right, sphinx test and/or lumbar spring is negative = right unilateral flexed sacrum
  • If deep sacral suclus is on the right, posterior/caudad ILA on the right, lateralization test is to the left, sphinx test and or/ lumbar spring test is positive = left unilateral extended sacrum
10
Q

What is a compensated L5?

A

If L5 is rotated in the opposite direction of the sacrum, is said to be compensated

11
Q

Which way does L5 sidebend in regards to the oblique axis of a sacral torsion?

A

Towards the oblique axis of a torsion

12
Q

Forward torsions (L/L ST or R/R ST) are considered flexed and in this regard which type of mechanics does L5 follow?

A
  • Type I mechanics
  • A flexed sacrum means a neutral L5
13
Q

Bacward torsions (L/R ST or R/L ST) are considered extended and what type of mechanics will L5 follow?

A
  • Type 2 mechanics
  • Extended sacrum = non-neutral L5 (Type 2)
14
Q

What are the L5 findings for a L/L ST and R/R ST?

A

L/L ST —-> L5 neutral SLRR

R/R ST —> L5 neutral SRRL

15
Q

What are the L5 findings for a L/R ST and a R/L ST?

A

L/R ST —-> L5 flexed/extended SRRR

R/L ST —> L5 flexed/extended SLRL

16
Q

If you have the sulci and ILA findings, but no seated flexion findings, how do you know the type of torsion?

A

Use the BBT or LS

17
Q

How does an uncompensated L5 affect our treatment?

A

You should treat L5 before the sacral dysfunction
