What divides ghe greater and lesser sciatic foramina?
Sacrospinous ligament.
pelvic diaphragm.
Composed of levator ani (iliococcygeus and pubococcygeus m) and coccygeus muscles.
Moves in concert w/ thoracoabdominal diaphragm to help return lymph back to heart.
Sacral motion: postural motion.
Sacral base moves ____ w/ forward bending.
Sacral base moves ___ w/ backward bending.
Sacral base moves posterior w/ forward bending. Sacral base moves anterior w/ backward bending.
Sacral motion: Respiratory motion.
During inhalation, sacral base moves______; during exhalation, sacral bae moves _____.
Inhalation: Sacral base moves posterior.
Exhalation: Sacral base moves anterior.
Sacral motion: Inherent motion.

During craniosacral flexion, sacrum ______.
During craniosacral extension, sacrum ______.
During CS flexion, sacrum extends or counternutates.
During CS extension, sacrum flexes or nutates.
Sacral motionL Dynamic motion.
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.
Anterior innominate rotation.
ASIS more inferiorly ipsilaterally.
PSPS more superior ipsilaterally.
Longer leg ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.
Posterior innominate rotation.
ASIS more superior ipsilaterally.
PSIS more inferior ipsilaterally.
Shorter leg ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.
Positive standing flexion test.
Ipsilateral anterior or posterior innominate rotation/shear.
Superior innominate shear (upslip, superior innominate subluxation)
ASIS and PSIS more superior ipsilaterally.
Pubic rami may be superior ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.
Inferior innominate shear.
ASIS and PSIS more inferior ipsilaterally.
AP compression restricted ipsilaterally.
Positive standing flexion test ipsilaterally.
Sacral torsion occurs in oblique axis, along w/ somatic dysfunction at ____?
L5.
L5 rule of sacrum.
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.
Forward sacral torsion.
Rotation is on the same side of the axis.
L on L sacral torsion.
Forward sacral torsion.
-R superior sculcus deeper.
-L ILA shallow.
-Positive seated flexion on Right.
-Restricted springing on left ILA
-L5 (NSLRR)
Standing flexion test.
Test iliac on sacrum.
Positive = ilium dysfunctionq
Greater anteriosuperior excursion = positive test.
Ipsilateral restriction of iliosacral motion.
Seated flexion test.
Test sacrum on ilium.
S.I.T. = SacroIliac Test.
Greater anterisuperior movement = positive test.
Positive test = ipisilateral restriction of sacroiliac motion. Sacrum dysfunction.
R on R sacral torsion.
-L superior sulcus deeper.
-R ILA shallow.
-Positive seated flexion test on Left.
-Restricted springing on R ILA.
-L5 (NSRRL)
Backward sacral torsion.
R on L.
-R superior sulcus shallow.
-L ILA deeper.
-Positive seated flexion on R.
-Positive lumbosacral spring test.
-Restricted springing on R superior sulcus.
-L5 (NNRLSL)
Positive seated flexion test.
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).
L on R sacral torsion.
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)
Bilateral sacral flexion.
-R and L superior sulci deep.
-Increased lumbar cure.
-ILA shallow bilaterally.
-Restricted sprining on ILA bilaterally.
-False neg seated flesion test.
Bilateral sacral extension.
-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.
