Sacrum/Pelvis review and counterstrain Lab Flashcards
what are the rules for L5 and sacrum
the sacral oblique axis will be to the same side as L5 sidebending
the sacrum rotates opposite of L5
the seated flexion test is positive on the opposite side of the oblique axis
when do the sacral vertebrae fuse for good
mid-twenties
respiration patterns of the sacrum
inhalation- extension
exhalation- flexion
move about the superior transverse respiratory axis
with lumbar flexion the sacrum
extends
bilaterally flexed and extended sacral dysfunctions occur about what axis
middle transverse axis (S3)
what muscles can cause a false positive seated flexion test?
ipsilateral quadratus lumborum (pulls the inominate up)
contralateral gluteus medius (hold the opposite innominate down)
what is the spring test
heel of hand over lumbosacral junction–> add gentle anterior compression force
puts L5 into extension and sacrum into flexion
