Sacral muscle energy - Exam 1

Question 1

What is the sacrum in when the ILA is uneven- there s a deep sulcus on the same side, and the seated flexion test is same side as deep sulcus?

Answer 1

• Unilateral sacral flexion

Question 2

What position is the sacrum in when the ILA is even, the sulci bilateral shallow.

Answer 2

Bilateral sacral extension

Question 3

What are some rules in sacral torsions?

Answer 3

L5 sidebending will engage oblique axis on that same side.

• L5 rotation and sacral rotation is opposite
• Seated flexion test is opposite the side of the oblique axis.

Question 4

What is a neutral - no flexion or extension, right pole moves forward relative to L5 is what?

Answer 4

Left on left

Question 5

Non-neutral- flexion or extension, sacrum rotates right, right pole moves backward is what?

Answer 5

Right on left

Question 6

In sacral torsions what occurs with weight bearing during walking
-Weight bearing left

Answer 6

• neutral

- L oblique axis

Question 7

Forward Sacral Torsion occurs when?

Answer 7

When the spine is in neutral. Left on left or right on right

Question 8

When does dysfunction in the form of a forward torsion occur?

Answer 8

When the sacral base moves forward, becomes restricted and does not rotate back as far as it should.

Question 9

What occurs when the left oblique axis is engaged?

Answer 9

Sacrum rotates left, right superior poles moves forward relative to L5, Left on left sacral torsion.

Question 10

What are the symptoms of a neutral dysfunction?

What direction is the sacrum in relation to the lumbar?

Answer 10

Symp - SI, inguinal, groin discomfort, Low back pain, increased lordotic curve.

• Sacrum rotated opposite lumbar
• L5 follows neutral mechanics

Question 11

When does a backward sacral torsion occur?

Answer 11

Occurs when the spine is in a non-neutral position.
Right on right
Left on left

Question 12

In a non-neutral bend over and twist

L5 sidebends and then rotates right (type II)

Answer 12

Right oblique axis is engaged, sacral base moves posteriorly, right superior pole moves forward relative to L5, Left on right

Question 13

What are the symptoms of a non-neutral somatic dysfunction?

Answer 13

Sym: Low back pain worse when bending backward. Decreased lordotic curve.

• L5 rotated and sidebent to the same side
• L5 rotates opposite the side of the sacrum rotation

Question 14

What is the difference between sacral torsion and sacral rotation?

Answer 14

• Sacral torsions have L5 rotation opposite the sacral rotation.
• Sacral rotations have L5 rotation the same as the sacral rotation

Question 15

What are the symptoms of Bilateral Sacral Flexion?

What are the signs on a test?

Answer 15

• Common following birth, Low back pain is main complaint, increased lumbar curve.
• Deep sulci and posterior ILA bilaterally, negative spring test, no change with backward bending test, and motion about middle transverse axis.

Question 16

What are the symptoms of Bilateral Sacral Extension?

What are the signs on a test?

Answer 16

• Low back pain, worse with backward bending, decreased lumbar curve
• ILA’s equal; sulci shallow bilaterally, positive spring test, ILA’s stay equal with backward bending test

Question 17

What are the causes of sacroiliac dysfunction?

Answer 17

1) Psoas
2) Short leg syndrome - deep sulcus is on the short leg
3) Postural imbalance
4) L5 problems
5) Disc problems
6) Simple trauma
7) Viscerosomatic reflexes

Question 18

Describe the process of walking?

Answer 18

The thoracic area rotates to the left, the lumbar area sidebends left, there is a torsional locking at the LS junction as the body of the sacrum is moving left, Shifting the weight to the left foot to be able to life the right.
The vertical center of gravity moves to the superior pole of the left SI, This locks in the left oblique axis, all this allows for there to be rotation to the left, The sacral base moves down on the right to conform to the lumbar curve. (just review end of slide show cause i’m lazy)
