Sacrum & Inominates

Question 1

What ligament divides the greater and lesser sciatic foramen?

Answer 1

Sacrospinous ligament

Question 2

What is the sacral respiratory motion and around what axis does it occur?

Answer 2

Inhalation = sacrum base rotates posteriorly (extension)
Exhalation = sacrum base rotates anteriorly (flexion)

Occurs around the Superior Transverse Axis

Question 3

What is the inherent/craniosacral motion and around what axis does it occur?

Answer 3

Craniosacral Flexion = Sacral base COUNTERNUTATES (rotates posteriorly/sacral extension)

Craniosacral Extension = Sacral base NUTATES (rotates anteriorly/sacral flexion)

This motion occurs around the Superior Transverse Axis

nute = nod

Question 4

Which way is the sacrum rotated if L5 (or group dysfunction of the lower lumbar region) is RrSr?

Answer 4

Sacrum is rotated to the left

Sacrum rotates in the OPPOSITE direction of L5

Question 5

Which side will the oblique sacral axis be engaged if L5 (or group dysfunction of the lower lumbar region) is RrSr?

Answer 5

There will be a Right Oblique axis

Oblique axis is in the SAME direction L5 is Sidebent

Question 6

Positive lumbosacral spring test indicates what?

Answer 6

Extension (posterior) sacral base

Question 7

Springing (motion) restricted over a part of the sacrum indicates what?

Answer 7

Restricted springing indicates posterior position

Question 8

Springing (motion) present over a part of the sacrum indicates what?

Answer 8

Springing present indicates anterior position

Question 9

What is a Forward Sacral Torsion?

Answer 9

When the rotation is on the same side as the axis

L on L; R on R

Question 10

What is a Backward Sacral Torsion?

Answer 10

When the rotation is on the opposite side of the axis

R on L; L on R

Question 11

Positive seated flexion test on the right indicates what?

Answer 11

Oblique axis is on the left

seated flexion is OPPOSITE the oblique axis

Question 12

What is the position of the sacrum when L5 is extended?

Answer 12

Sacrum is flexed (nutated)

sacrum is opposite L5 f/e

Question 13

Hypertonicity of what muscle(s) can cause an Anterior Inominate rotation?

Answer 13

Hypertonicity of the Quads can cause ant rotation

Question 14

What muscles do you target in ME treatment for an Ant Inominate Rotation SD?

Answer 14

Hamstrings are targeted

Strengthening hamstrings causes stretching of quads

Question 15

How do you determine laterality in inominate dysfunctions?

Answer 15

Standing Flexion OR ASIS Compression Test
