SIJ Flashcards
What does the Laslett SIJ CPR include and how do you use the results of the tests to rule IN SIJ?
- Distraction
- Thigh thrust
- Compression
- Sacral Thrust
2 or more + provocation tests rules IN SIJ
Which 2 provocative SIJ tests would you perform first and why?
- Thigh thrust (specific)
- distraction (sensitive)
If you performed combined repeated motions of lumbar spine and your patient does NOT CENTRALIZE, then ______ improves from 78% to 87% for SIJ.
Specificity
If a pt’s pain subsides when you mobilize their innominate into anterior rotation, what manual interventions may they benefit from?
- continue mobilization anteriorly (prone w/ leg ext or in lumbar sidelying manip position)
- MET: recruit hip flexors, relax, then move innominate into more ant rot
- Lumbar sidelying manip
- MET P/A: recruit glute/QL mm, followed by ant force
If a pt’s pain subsides when you mobilize their innominate into posterior rotation, what manual interventions may they benefit from?
- continue mobilization posteriorly
- MET of HS/glutes, then move innominate into more post rotation (3-5 sec holds, 3-5x)
- Lumbopelvic manip (banana)
- mobilize innominate A/P
- MET A/P: recruit iliopsoas/obliques (small ant hip hike, relax, distraction stretch)
When walking, your innominate moves in the ____ direction during swing phase and ____ direction with heel strike
- posterior rotation
- anterior rotation
There is controversy over how much the SIJ moves. Current studies support limited motion of ~___ degrees in all 3 plans
2 degrees
what 2 ligs resit nutation?
sacrotuberous
iliolumbar
what lig resists counternutation?
posterior sacroiliac (strongest lig)
What is the fortin finger test?
Pts w/ SIJ pn often point right to the SIJ/buttock
What is the diagnostic accuracy of the 4 SIJ pain provocation tests?
we can use the test cluster to rule OUT SIJ dysfunction, but not effective at ruling IN SIJ dysfunction
