Question 18

what occurs as compensation if you have limited hip flexion?

Answer 18

posterior tilt and trunk flexion

Question 19

what occurs as compensation if you have limited hip extension?

Answer 19

anterior tilt and trunk extension

Question 20

Answer 20

1/3

Question 21

if in neutral stance, HAT causes what?

Answer 21

joint compression

Question 22

what occurs if you aren’t in neutral stance?

Answer 22

muscle contraction & joint compression

Question 23

when you have limited hip abduction, what is the compensation?

Answer 23

pelvic elevation

Question 24

name the normative values for stair climbing.

Answer 24

45-65 degrees

Question 25

Answer 27

120 degrees

Question 28

what allows for compensation when you have limited hip flexion?

Answer 28

tightness of hip ligaments

Question 29

when you have a bilateral hip flexor tightness on standing posture, what two things occur?

Answer 29

increase lordosis or anterior pelvic tilt/trunk lean

Question 30

what is the primary role of the hip abductors?

Answer 30

to maintain a level pelvis

Question 31

describe what is happening in a unilateral stance without lean.

Answer 31

MA increases as the COG moves over; adduction torque forms causing you to need a higher abduction force to overcome the adduction force; muscle force causes compression

Question 32

in unilateral stance, what does a compensatory lean to the same side allow for?

Answer 32

decrease in MA, and decrease in joint compression by 1/2, decrease JRF,

Question 33

what occurs during single stance stability when using a cane on the contralateral side?

Answer 33

decrease hip abduction force and torque by 20-40%; and decrease hip JRF

Question 34

when are hip adductors functionally important?

Answer 34

during the swing stance phase and during squatting

Question 35

holding a load on the ipsilateral side will allow for what?

Answer 35

hip abductor moment, decrease in need for hip abductor force and moment, decrease in JRF

Question 36

holding a load on the contralateral side will allow for what?

Answer 36

hip adductor moment, increase in need for hip abductor force and moment, increase in JRF

Question 37

what is better, non-weight bearing ambulation or toe touch (if with weak hip abductors)?

Answer 37

toe touch

Question 38

Answer 38

anterior roll, posterior glide; inferior glide >70 degrees

Question 39

hip extension arthrokinematic

Answer 39

posterior roll, anterior glide

Question 40

hip abduction arthrokinematic

Answer 40

lateral roll, medial glide

Question 41

hip adduction arthrokinematic

Answer 41

medial roll, lateral glide

FIA can also cause what other two impingements?

Answer 42

CAM and Pincer
