Lab- Sacrum Flashcards
what is the treatment position for a piriformis counterstrain?
flexion, abduction, and external rotation
how do you find the piriformis ternderpoint?
it is halfway between the greater trochanter and the sacral ILA
what does the seated forward bending test tell us?
which sacral base is stuck
what is important to make sure your patient does during the seated forward bending test?
they must have their feet flat on the ground
how do you get a positive seated forward bending test?
one PSIS moves father superiorly at the end range of motion
for a torsion, what side will the positive seated forward bending test be on?
on the non-axis side
what could a positive seated forward bending test on the left indicate?
a left unilateral flexion, a left unilateral extension, or a right axis torsion
what happens to the lumbar lordotic curve during inhalation?
it decreases (flattens)
what happens to the sacral base during inhalation?
it moves posteriorly
what happens to the sacral apex during inhalation?
it moves anteriorly
what happens to the lumbar lordotic curve during exhalation?
it increases
what happens to the sacral base during exhalation?
it moves anteriorly
what happens to the sacral apex during exhalation?
it moves posteriorly
what does the lumbar spring test tell us?
whether the sacrum will move anteriorly
what does a positive lumbar spring test indicate?
a preference for posterior/backward sacral base motion
what could a negative lumbar spring test indicate?
flexed dysfunction- right or left unilateral flexion; or a flexed/forward torsion: right on right sacral torsion or left on left sacral torsion; bilateral flexion
what does the backward bending test/sphinx test tell us?
whether the sacral base will move anteriorly
what should happen when the patient pushes up on their hands into an extended position?
the sacral base should move anteriorly and the ILAs should move posteriorly
what does a positive backward bending test indicate?
posterior/backward dysfunction
what does a negative backward bending test indicate?
a flexed/forward dysfunction
whenever we are treating either a unilateral or bilateral sacral dysfunction, what should we do first?
we need to gap the SI joint
if the sacrum is flexed, how do we gap the SI joint?
we need to abduct and internally rotate in order to gap the posterior SI joint
if the sacrum is extended, how do we gap the SI joint?
abduct and externally rotate in order to gap the anterior SI joint
when is the one time that the results of the BBT and the lumbar spring are not the same?
when you have a bilaterally extended sacrum
how do you treat a bilaterally extended sacrum (after gapping the SI joint)?
you place your hand at the sacral base; push down with exhalation; resist with inhalation
how do you treat a bilaterally flexed sacrum (after gapping the SI joint)?
you place your hand at the apex of the sacrum; push down with inhalation; resist with exhalation
how do you treat a left unilateral flexed sacrum?
you place your hand at the left ILA; push on inhalation and resist on exhalation
if we have a left on left sacral torsion, where is the barrier??
you must maintain the axis- rotate right on left axis- just switch the direction of rotation
when treating torsions, how should you decide which hip goes down on the table?
the hip of the axis side is always on the table
what would be the compensated L5 of a left on left Sacral torsion?
L5 N Rr Sl
when treating a flexed/forward sacral torsion with ME/ART, what position should the patient be in?
a modified sims position
what would be the compensated L5 of a left on right sacral torsion (extended/backward)?
L5 F/E Rr Sr
