foundation of trunk

maintain stability of trunk during movement

transmits force during gait

Posterior pelvic tilt

Answer 11

ASIS goes superior

PSIS goes inferior

ischial tuberosity goes inferior

Question 12

R heel strike

Answer 12

R innominate rotates posteriorly (as bring R leg forward & heel strikes ground)

Answer 13

R innominate rotates anteriorly

Question 14

Innominate shear

all parts of innominate move superiorly

Question 15

Pubic shear

Answer 15

pubic tubercle moves superior or inferior

Question 16

Answer 16

assoc w/ ASIS

in flare as ASIS moves medial

Quadratus lumborum
Erector Spinae
SI joint
Piriformis
Hamstring
Quads
Adductors

Question 18

ASIS compression test

Answer 18

adding motion to SI joint

add posterior medial compression

Question 19

What happens in a healthy ASIS compression test?

Answer 19

as push down on R, hand will slightly slide down & left will shift up

Question 20

Standing flexion test

Answer 20

put hands on PSIS & have bend forward

does innominate stabilize?

asymmetry on dysfunctional side (PSIS will rise up)

Question 21

R Anterior Rotated Innominate

Answer 21

ASIS on R is inferior
PSIS on R is superior
Public tubercles are even

Question 22

R Posterior Rotated Innominate

Answer 22

ASIS is superior on R
PSIS is inferior on R
Pubic tubercles are even

shortened R leg

Question 23

R superior innominate shear

Answer 23

ASIS & PSIS & pubic tubercles on R side are all shifted superiorly along w/ iliac crest

Question 24

R inferior innominate shear

Answer 24

all landmarks on R side will be inferior compared to L
