During initial contact, knee extension should be ___ for TT and ___ for TF

Answer 3

0-5 for TT

0 for TF

Question 4

True or False:

the prosthetic side should be abducted

Answer 4

false, it should not be and will add instability

Question 5

The prosthetic side should not be ____ and the sound limb should not be ____

Answer 5

abd; add

Question 6

During initial contact, forceful knee extension should be avoided in the (TT/TF) patient

Answer 6

TF

Question 7

During loading response what are the events for both TT and TF patients

Answer 7

TT: knee flexion and PF
TF: straight knee increases energy cost

Question 8

What phase of gait does transverse rotation forces tend to rotate the prosthetic limb, which is why rotator components are added

Answer 8

loading response

Question 9

What are the events for mid stance

Answer 9

controlled tibial advancements
lateral hip stability
erect trunk

Question 10

During mid stance, amputees dont have the ability to maintain body weight over prosthesis which results in a ____ ___ of the trunk and (increase/decrease) stability

Answer 10

lateral lean; decrease

Question 11

Mid stance may look normal if they don’t have what two deviations

Answer 11

pelvic horizontal dip and decreased prosth. stance time.

Question 12

What stance of gait can causes excessive lumbar lordosis if a patient has a hip flexion contracture

Answer 12

terminal stance

Question 13

Which phase of gait requires 40 degrees of knee flexion with all passive motion

Answer 13

pre swing

Question 14

Which phase of gait do amputees frequently “kick” the prosthetic limb? And during this kicking of the limb, a (anterior/posterior) rotation of the pelvis occurs

Answer 14

Pre-swing; posterior

Question 15

In what phase of gait to TF patients flex the knee 20% lateral than normal

Answer 15

pre swing

Question 16

Initial swing requires __ of knee flexion, __ of hip flexion, and to lift the limb from the floor

Answer 16

60 of knee flexion

15 of hip flexion

Question 17

most amputees have limited _____ pelvic rotation which (increases/decreases) knee flexion which results in (stronger/poorer) clearance of limb.

Answer 17

forward
decreases
poorer

Question 18

What is one of the most important things to work on with amputees during gait

Answer 18

pelvic rotation

Question 19

During mid swing, TT have the ability to control the forward propulsion of the tibia, but what must TF rely on

Answer 19

cadence control devices within the knee

Question 20

During terminal swing, we want full knee extension for ___ ___ and deceleration of the thigh for ___ ___.

Answer 20

step length; heel contact

Question 21

Typically, does the sound limb or prosthetic limb have a longer step length

Answer 21

prosthetic limb

Question 22

A stiff bumper will cause excessive knee ____ and a soft PF bumper will cause ___

Answer 22

flexion; extension (decreased knee flexion)

Question 23

A patient wearing higher heeled shoes will causes more ____ and lower heels cause more ____

Answer 23

flexion

extension (decreased knee flexion)

Question 24

insufficient sock flexion will cause (increased/decreased) knee flexion

Answer 24

decreased

Question 29

Ligamentous laxity in a patient can cause

Answer 29

lateral and medial knee thrust

Question 30

increased foot inset causes (medial/lateral) knee thrust

Answer 30

lateral

Question 31

increased foot outset causes (medial/lateral) knee thrust and (adducted/abducted) gait

Answer 31

medial; abducted

Question 32

Answer 32

medial; lateral
