Sacral SD Flashcards
What lateralization test do you do for static testing?
Seated forward bending test
tests side of dysfunction, negative bilateral dysfunction
Unilateral SeFBT means?
Torsion SeFBt test means?
positive on side of dysfunction
positive on the opposite of the side of the axis
What should happen first in the SeFBT?
Where should you hands be to assess?
Feet both flat on the floor!
inferior aspect on the pt PSIS
What are the active motion tests?
What do they examine?
backward bending test, respiratory motion
flexion and extension motion
BBT or sphinx
pt prone
eye at level of of sacral sulci
pt in tv watching position
+ if asymmetry worsens w movement/ asymmetrical throughout
extended sacrum!
(- is flexed)
What way should a bilateral sacral base move?
posteriorly during inhalation, and anteriorly during exhalation
Steps of the lumbar spring test?
pt prone
heel of hand on the lumbosacral junction
pressured down through the table
+ is an extended sacrum and doesn’t move well into extension
What are the passive motion test?
lumbar spring (flexion and extension)
oblique axis passive motion (dysfunction oblique axis)
How would you examine the oblique axes of motion?
pt prone
monitor sacral sulcus with one hand and contralateral ILA with other
apply ant pressure alternatively on ILA and sulcus
checks for posterior motion at opposite sulcus/ILA
What are the sacral axes?
superior transverse axis (s2 posteriorly)
middle transverse axis (s2 anteriorly)
inferior transverse axis (s3 posteriorly)
left and right oblique axis
vertical axis
if the base is held anteriorly then what type of torsion is it?
flexed or forward torsion
if the base is held posteriorly then what type of torsion is it?
extended or backward torsion
What will you have if you have a L/L ST?
BBT - negative
-gets better, same letter
lumbar spring - negative (ease w spring)
SeFBT - + on R
deep sacral sulcus on R
posterior/caudal ILA on L
What will you have if you have a R/R ST?
BBT - negative
-gets better, same letter
lumbar spring - negative (ease w spring)
SeFBT - + on L
deep sacral sulcus on L
posterior/caudal ILA on R
What will you have if you have a L/R ST?
BBT - positive
-gets worse, stays the same
lumbar spring - positive (difficult w spring)
SeFBT - + on L
deep sacral sulcus on R
posterior/caudal ILA on L
What will you have if you have a R/L ST?
BBT - positive
-gets worse, stays the same
lumbar spring - positive (difficult w spring)
SeFBT - + on R
deep sacral sulcus on L
posterior/caudal ILA on R
if the base is held anteriorly then what type of unilateral is it?
flexed or forward uni
if the base is held posteriorly then what type of unilateral is it?
extended or backward uni
what side is the sacral sulcus and ILA if it is a unilateral dysfunction?
same side!
What will you have if you have a RSF?
BBT - negative
-gets better, same letter
lumbar spring - negative (ease w spring)
SeFBT - + on R
deep sacral sulcus on R
posterior/caudal ILA on R
What will you have if you have a LSF?
BBT - negative
-gets better, same letter
lumbar spring - negative (ease w spring)
SeFBT - + on L
deep sacral sulcus on L
posterior/caudal ILA on L
What will you have if you have a LSE?
BBT - positive
-gets worse, stays the same
lumbar spring - positive (difficult w spring)
SeFBT - + on L
deep sacral sulcus on R
posterior/caudal ILA on R
What will you have if you have a RSE?
BBT - positive
-gets worse, stays the same
lumbar spring - positive (difficult w spring)
SeFBT - + on R
deep sacral sulcus on L
posterior/caudal ILA on L
What will you have if you have a Bilateral sacrum flexed?
extended?
Bilat deep sacral sulcus
bilat posterior ILA
neg SeFBT
What will you have if you have a Bilateral sacrum extended?
Bilat shallow sacral sulcus
bilat anterior ILA
neg SeFBT
compared to the sacrum, how is L5 rotated if compensated?
opposite direction for balance
SB towards the oblique axis of the torsion
if it isn’t then its uncompensated
if the sacrum is flexed, then L5 is?
L5 neutral
type 1
if the sacrum is extended, then L5 is?
L5 flexed of extended
type 2
How does the sacrum move in respiration?
inhalation - base-posterior, apex-anterior
- abd cavity increase in AP diameter as diaphragm flattens
exhalation: base-anterior, apex-posterior
- abd cavity decrease in AP diameter as diaphragm domes
What is sacral extension?
sacral flexion?
How do you tell with respiration?
extension - base tips posterior, apex moves anteriorly
oppo for flexion
movement inhalation restricted = BS flexion
exhalation restriction = BS extension
What are the letters (R or L) for a forward torsion?
letters for an backward torsion?
forward are the same (flexed)
R/R or L/L
backward is backwards (extend)
R/L or L/R
what can you do to gap the SI joint in flexed or extended? What does gapping the SI joint do?
flex - IR
extend - ER
it allows the base to move
if the oblique rocking interpretation has better motion with left thumb on left ILA, and right thumb on right sacral sulcus,
then what are possible torsions it can be?
R/L ST
L/L ST
if the oblique rocking interpretation has better motion with left thumb on left sacral sulcus, and right thumb on right ILA,
then what are possible torsions it can be?
R/R ST
L/R ST
