During craniosacral extension, sacrum ______.

Back 5

During CS flexion, sacrum extends or counternutates.
During CS extension, sacrum flexes or nutates.

Front 6

Sacral motionL Dynamic motion.

Back 6

Motion that occurs during ambulation. Sacrum engages wo sacral oblique axes.
Wt bearing on the left leg (stepping forward w/ right leg) will cause left sacral axis to be engaged.

Front 7

Anterior innominate rotation.

Back 7

ASIS more inferiorly ipsilaterally.
PSPS more superior ipsilaterally.
Longer leg ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.

Front 8

Posterior innominate rotation.

Back 8

ASIS more superior ipsilaterally.
PSIS more inferior ipsilaterally.
Shorter leg ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.

Front 9

Positive standing flexion test.

Back 9

Ipsilateral anterior or posterior innominate rotation/shear.

Front 10

Superior innominate shear (upslip, superior innominate subluxation)

Back 10

ASIS and PSIS more superior ipsilaterally.
Pubic rami may be superior ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.

Front 11

Inferior innominate shear.

Back 11

ASIS and PSIS more inferior ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.

Front 12

Sacral torsion occurs in oblique axis, along w/ somatic dysfunction at ____?

Back 12

L5.

Front 13

L5 rule of sacrum.

Back 13

when L5 is sidebent, sacral oblique axis is engaged on the same side as the sidebending.
When l5 is rotated, sacrum rotates the opposite way on an oblique axis.
Seated flexion test if found on the opposite side of the oblique axis.

Front 14

Forward sacral torsion.

Back 14

Rotation is on the same side of the axis.

Front 15

L on L sacral torsion.

Back 15

Forward sacral torsion.
-R superior sculcus deeper.
-L ILA shallow.
-Positive seated flexion on Right.
-Restricted springing on left ILA
-L5 (NSLRR)

Front 16

Standing flexion test.

Back 16

Test iliac on sacrum.
Positive = ilium dysfunctionq
Greater anteriosuperior excursion = positive test.
Ipsilateral restriction of iliosacral motion.

Front 17

Seated flexion test.

Back 17

Test sacrum on ilium.
S.I.T. = SacroIliac Test.
Greater anterisuperior movement = positive test.
Positive test = ipisilateral restriction of sacroiliac motion. Sacrum dysfunction.

Front 18

R on R sacral torsion.

Back 18

-L superior sulcus deeper.
-R ILA shallow.
-Positive seated flexion test on Left.
-Restricted springing on R ILA.
-L5 (NSRRL)

Front 19

Backward sacral torsion.
R on L.

Back 19

-R superior sulcus shallow.
-L ILA deeper.
-Positive seated flexion on R.
-Positive lumbosacral spring test.
-Restricted springing on R superior sulcus.
-L5 (NNRLSL)

Front 20

Positive seated flexion test.

Back 20

Indicates contralateral sacral axis rotation.
Ex: positive seated flexion on R always indicates a L axis sacral torsion (b/c the rotation of that axis allows greater excursion of contralateral sacrum--i.e. superior sulcus).

Front 21

L on R sacral torsion.

Back 21

Backward sacral torsion.
-L superior sulcus shallow.
-R ILA deeper.
-Positive seated flexion on L.
-Positive lumbosacral spring test.
-Restricted springing on L superior sulcus.
-L5 (NNRRSR)

Front 22

Bilateral sacral flexion.

Back 22

-R and L superior sulci deep.
-Increased lumbar cure.
-ILA shallow bilaterally.
-Restricted sprining on ILA bilaterally.
-False neg seated flesion test.

Front 23

Bilateral sacral extension.

Back 23

-R and L superior sulci shallow.
-Decreased lumbar cure.
-ILA deeper bilaterally.
-Positive lumbosacral spring test.
-Restricted springing on superior sulci bilaterally.
-False neg seated flexion test.
