SIJ/Pelvis

Question 1

tension erector spinae aponeurosis and correct motions/support specific joints

Question 12

What limits force production by multifius?

Answer 12

short length

Question 13

What muscle recruitment pattern is more common in response to LBP?

rectus abdominus
QL
erector spinae

Question 16

When hip is flexing, can psoas provide stabilization at spine?

Answer 16

yes, can provide compressive forces

Question 17

Which hip motions is coupled with pelvic anterior rotation?

Answer 17

hip extension

Question 20

Which ligament controls posterior rotation of pelvis?

Answer 20

sacrotuberous

Question 21

What sacral motion occurs with trunk extension?

Answer 21

flexion

Question 22

Which trunk motion occurs with sacral extension

Answer 22

flexion

Question 23

What is a positive active straight leg raise test?

Answer 23

ASLR strength improving with pelvic compression.

Indicative of joint hypermobility on weak side

Question 24

What may lead to false negative on ASLR?

Answer 24

not using weight.

Sometimes weight of leg is not enough to discern weakness

Question 25

Cluster of findings to seperate hypermobile pubis from hypomobile SIJ

Answer 25

Answer 27

``` Distraction Compression FABER thigh thrust Gaenslan ``` if less than 3 are positive, between 72 and 99% chance of no SIJ pain

Question 28

Distraction and compression are (sensitive/specific) for pelvic fracture/instability?

Answer 28

sensitive

Question 29

Fortin test

Answer 29

When patient points at pain, should be within 1cm of PSIS

Question 30

Patrick test is also known as?

Answer 30

FABER

Question 31

Is hip scour more sensitive or specific?

Answer 31

sensitive

Question 32

Hip OA by restricted motion

Answer 32

3 or more planes of restricted motion

Answer 38

slightly lateral and inferior to PSIS
