Final Exam: Gait Training Flashcards
A knee flexion contracture greater than ___ degrees greatly affect gait
10
Which view is best to analyze gait
AP and lateral on prosthetic side
During initial contact, knee extension should be ___ for TT and ___ for TF
0-5 for TT
0 for TF
True or False:
the prosthetic side should be abducted
false, it should not be and will add instability
The prosthetic side should not be ____ and the sound limb should not be ____
abd; add
During initial contact, forceful knee extension should be avoided in the (TT/TF) patient
TF
During loading response what are the events for both TT and TF patients
TT: knee flexion and PF
TF: straight knee increases energy cost
What phase of gait does transverse rotation forces tend to rotate the prosthetic limb, which is why rotator components are added
loading response
What are the events for mid stance
controlled tibial advancements
lateral hip stability
erect trunk
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
lateral lean; decrease
Mid stance may look normal if they don’t have what two deviations
pelvic horizontal dip and decreased prosth. stance time.
What stance of gait can causes excessive lumbar lordosis if a patient has a hip flexion contracture
terminal stance
Which phase of gait requires 40 degrees of knee flexion with all passive motion
pre swing
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
Pre-swing; posterior
In what phase of gait to TF patients flex the knee 20% lateral than normal
pre swing
Initial swing requires __ of knee flexion, __ of hip flexion, and to lift the limb from the floor
60 of knee flexion
15 of hip flexion
most amputees have limited _____ pelvic rotation which (increases/decreases) knee flexion which results in (stronger/poorer) clearance of limb.
forward
decreases
poorer
What is one of the most important things to work on with amputees during gait
pelvic rotation
During mid swing, TT have the ability to control the forward propulsion of the tibia, but what must TF rely on
cadence control devices within the knee
During terminal swing, we want full knee extension for ___ ___ and deceleration of the thigh for ___ ___.
step length; heel contact
Typically, does the sound limb or prosthetic limb have a longer step length
prosthetic limb
A stiff bumper will cause excessive knee ____ and a soft PF bumper will cause ___
flexion; extension (decreased knee flexion)
A patient wearing higher heeled shoes will causes more ____ and lower heels cause more ____
flexion
extension (decreased knee flexion)
insufficient sock flexion will cause (increased/decreased) knee flexion
decreased
excessive sock flexion will cause (increased/decreased) knee flexion
increased
If the foot is too far posterior the socket will be too far (ant/post) which causes ___ ___ ___
ant; excessive knee flexion
If the foot is too far anterior, the socket will be to far ____ which causes ___ ___ __-
posterior; decreased knee flexion
An increased abducted socket can cause increase ___ knee ___
lateral knee thrust
Ligamentous laxity in a patient can cause
lateral and medial knee thrust
increased foot inset causes (medial/lateral) knee thrust
lateral
increased foot outset causes (medial/lateral) knee thrust and (adducted/abducted) gait
medial; abducted
Weak hip abductors can cause (medial/lateral) knee thrust and a (medial/lateral) trunk lean
medial; lateral
What will happen if the prosthesis is too short
lateral trunk lean
What will happen if the prosthesis is too long
abducted gait
why does vaulting occur
prosthesis is too long
why does rotation of prosthesis occur
heel response is too hard
weak hip rotators
poor pelvic control
decreased WB
Why does toe drag happen
prosthesis too long and inadequate pelvic control
