Gait devation

Question 1

lateral leaning over prosthetic side

Answer 1

lateral trunk bending

Question 2

prosthetic foot too far lateral/ onset
weak hip abd
prosthetic too short/ abd
pain/ bone spurs on distal lateral femur

abd contracture/ hip pain

Answer 2

lateral trunk bending

Question 3

PF of intact limb to clear prosthetic
assist in clearance of prosthetic limb

Answer 3

Vaulting

Question 4

prosthetic too long
excessive knee friction (not allowing it to unlock in time)

Answer 4

Vaulting

Question 5

sudden knee flexion at end of SLS before DLS

Answer 5

drop off

Question 6

toe lever too soft/ short
heel height too tall
- puts tibia in anterior tilt position/ facilitate knee flex

poor eccentric control of PF (soleus)

Answer 6

drop off

Question 7

valgus of knee BKA during midstance

Answer 7

excessive valgus

Question 8

foot too lateral compared to socket
foot too inverted
poor integrity of MCL

Answer 8

Excessive valgus

Question 9

Varus of knee BKA

Answer 9

excessive varus

Question 10

too much medial lateral dimension of socket (leg moving inside socket)

foot too everter or in set compared to socket

poor LCL intergrity

Answer 10

Excessive varus

Question 11

rapid slap at heel inital contact

Answer 11

foot slap

Question 12

insufficient PF resistance in prosthetic foot

heel too soft

Answer 12

Foot slap

Question 13

foot turned out, result in shorter stance time because toe lever is shortened

Answer 13

excessive toe out

Question 14

too much ER of prosthetic foot

Answer 14

Excessive toe out

Question 15

lateral movement of forefoot at start of stance phase, whip motion

Answer 15

ER of foot at Inital contact

Question 16

heel mechanism too firm (become fulcrum and motion occurs around it instead of it absorbing form)

movement occurs when socket is too loose

Answer 16

ER of foot at initial contact

Question 17

slow procession through stance phase
wobbly knee
lean fwd on AD to avoid quad demand

Answer 17

knee instability

Question 18

weak quad/ deconditioning

excessive socket flex/ DF (socket ant tilted)

poor eccentric control PF (soleus)

hip flex contracture- excess socket flex

Answer 18

knee instability

Question 19

throwing leg fwd at terminal stance to lock out

clunk sound for full ext

Answer 19

Terminal impact/ past retract

Question 20

inadequate resistance to knee ext
need sensory input/ confirmation knee is locket out

Answer 20

Terminal impact/ past retract

Question 21

hip hike on prosthetic side during swing phase

energy demand and cause LBP

Answer 21

pelvic elevation, hip hike

Question 22

prosthetic limb too long

Answer 22

pelvic elevation, hip hike

Question 23

heel whips lateral at start of swing phase

Answer 23

lateral whip

Question 24

poor rotation of knee bolt
weak hip rotators

heel cushion too stiff (pivot point)

Answer 24

lateral whip

Question 25

wide arc of prosthetic limb during swing phase

Answer 25

circumduction

Question 26

excessive knee flex resistance
antalgic gt if socket rubs, excessive high medial brim (pinch)

abd contracture, prosthetic foot too PF or prosthetic too long

Answer 26

Circumduction

Question 27

wide BOS through entire
prosthetic never comes to midline

Answer 27

abducted gait

Question 28

excessive medial brin height pinch/ pain

excessive volume of thigh won’t fit in socket

abd contracture

Answer 28

Abducted gait

Question 29

heel whips medially at start of swing

Answer 29

medial whip

Question 30

excessive knee axis ER, prosthesis donned in ER, weak hip rotators

heel cushion too stiff (pivot point)

Answer 30

medial whip
