fibrocarilangoues

Question 7

SI jt. motion is designed for _______and has very little _______

Answer 7

stability; mobility

Question 8

What is the RSA

Answer 8

high accurate technique of imagining 3-D position and motion (used for SI due to tiny movements)

Question 9

incidence: SI jt dysfunction is seen 20% during ______

Answer 9

pregnancy

Question 10

SI jt. dysfunction Risk Factors:

Answer 10

laxity and hormonal changes
During pregnancy
-prior LBP
-Prior pelvic trauma
Not pregnant -non located

Question 11

Etiology of SI jt. dysfunction:

Answer 11

primarily -peri partum
immature skeletons due to lack of bony irregularity and congruency
trauma
disease (autoimmune conditions like AS)

Question 12

Symptoms of SI jt. dysfunction

Answer 12

localized SIJ (100% of the time)
gluteal region and lateral hip
Possibly pubic symphysis P!
hypermobility/instability

Question 13

SI jt. Dysfunction signs:
A/PROM
Resisted testing/MMT
Stress tests (SI provocation )

Answer 13

no consistent pattern w/just SI dysfunction
—may have concurrent lumbar condition

Impaired local mm.
weak anti-gravity hip mm.

At least 3(+)
lack support unless together

Question 14

SI jt. Dysfunction signs:
special test:
–motion tests:
–ASLR

Answer 14

palpation for position - unreliable
March or Gilett test MOST useful but still unreliable
ASLR (+) for impaired local mm

Question 15

What is the gold standard for diagnostic?

Answer 15

SI block

Question 16

PT Rx: SI jt. dysfunction

Answer 16

POLICED
STM/Muscles energy techniques/mods/ acupuncture for P!/ muscles guarding
pelvic belt
JM (improved symptoms and clinical findings)
–DID NOT alter positions
–(+) soft tissue and mm. influence

Question 17

PT Rx: MET
SI jt. dysfunction

Answer 17

the primary focus is stabilization
–local mm (like lumbar hyper/instability)
–hip mm. hamstrings and GMAX blend w/sacrotuberous lig.
–TLF blends w/ lat. TA, Erector Spinae, and iliolumbar lig.

Question 18

PT Rx: Education

Answer 18

reduce fear
early mobilization w/o provocation
general anatomy, biomechanics benefits of coordination ther ex
reassurance of good prognosis
