Q

4 steps to make the somatic dysfunction diagnosis?

A

Perform seated flexion test
Palpate the sacral landmarks
Motion tests
Palpate L5

21
Q

Seated flexion test?

A

place thumbs under PSIS
patient flexes forward with feet on the floor
side with last superior movement is side of sacroliliac restriction (pos side)

22
Q

Confirm seated flexion test?

A

ASIS compression test

23
Q

ASIS compression test?

A

positive test, restriction of posteriormedial pressure indicates SI restriction on ipsilateral side

24
Q

Is there an oblique axis?

A

A positive seated flexion test/ASIS compression test typically indicates the sacral oblique axis is on the opposite side

ex) a positive right seated flexion/ASIS compression test indicates a left oblique axis

25
Q

Describe the 2 possible motions around an oblique axis?

A

Forward on a right axis
left anterior sacral base and right posterior/inferior ILA (inferior lateral angle)
right sacral rotation on right oblique axis
rotation is opposite the anterior sacral base
R/R or right on right
Backward on a right axis
right anterior sacral base and posterior/inferior base on the left
left rotation on a right oblique axis
L/R or left on right

26
Q

What does lumbar findings (L5) tell you about sacral rotation and sacral oblique axis?

A

If L5 is rotated, sacrum rotates in opposite direction on an oblique axis
If L5 is sidebent to one side, a sacral oblique is typically enlarged on the same side

27
Q

Does not involve an oblique axis?

A

unilateral flexion/ extension

bilateral flexion/ extension

28
Q

Evaluate range of motion of sacroiliac joint?

A

seated flexion test and/or ASIS compression test
Backward bending test
lumbosacral springing test

29
Q

Palplate the static sacral landmarks?

A

Sacral base, named for anterior side

Inferior lateral angle, names for side that is more posterior/ inferior

30
Q

Tests that evaluate the sacral base/ lumbosacral junction to flex?

A

Lumbar spring test, Backward bending test

31
Q

If sacrum is already flexed?

A

then there is no problem flexing it more, get a negative test
Forward sacral torsion, forward sacral rotation, unilateral flexion, bilateral flexion

32
Q

If the sacrum is extended?

A

then it cannot flex more and you get a positive test

backward sacral torsion, backward sacral rotation, unilateral extension, bilateral extension

33
Q

Lumbar spring test?

A

Pos=resistance to springing, sacral extension or backward rotation on oblique axis
neg= ease of spring, sacral flexion or forward rotation/torsion

34
Q

Backward bending test?

A

pos=increased sacral base asymmetry, sacral extension or backward rotation on oblique axis
neg= decreased sacral base asymmetry, sacral flexions or forward rotation or torsion

35
Q

Therefore a negative test or spring indicates?

A

unilateral or bilateral sacral flexion, R on R/ L on L

36
Q

Therefore a positive test or no spring?

A

unilateral or bilateral sacral extension, R on L/ Lon R

37
Q

Determine the axis?

A

Opposite side of positive seated flexion/ ASIS compression test
Opposite side of tight piriformis muscle
tests to determine motion restriction

38
Q

L5 rotation is opposite the sacrum?

A

Sacral torsion

39
Q

L5 rotation is same side as sacrum?

A

Sacral rotation

40
Q

Treatment of sacral rotation vs torsion?

A

same

41
Q

Unilateral Sacral flexion?

A

Base anterior and ILA posterior/inferior on same side of positive flexion/ASIS
Cause- hard landing on foot or ischial tuberosity
may be accompanied bu superior innominate shear or posterior innominate rotation

42
Q

Unilateral sacral extension?

A

Base anterior and ILA p/i on opposite side of positive seated flexion/ASIS
cause- strong leg tug
may be accompanied by inferior innominate shear or anterior innominate rotation

43
Q

If low back pain not have positive seated flexion or ASIS compression and sacral landmarks are symmetrical?

A

check to see if lumbar curve is reduced/ exaggerated
motion test the sacrum
use the spring and backward bending test (pos indiactes bilateral sacral extension)

44
Q

Positive seated flexion test/ASIS compression test?

A

palpate sacral base and ILA

45
Q

Negative seated flexion test/ ASIS compression test?

A

check pelvis or lumbar spine

46
Q

Base anterior, ILA opposite?

A 
Do motion test
 Extension restrict= forward rotation
 flexion restrict= backward rotation
Test L5 rotation
 Opp sacrum= sacral torsion
 Same sacrum= sacral rotation
47
Q

Base anterior, ILA same side?

A

Seated flexion test + same side= unilateral flexion

Seated flexion test + opp side= unilateral extension

48
Q

Neg spring test indicates?

A

That the sacrum can move into flexion and its restricted in extension, therefore backward rotation
