Question 8

how to counteract contracture formation

Answer 8

regular scheduled time in prone positions

avoid pillows under stump in supine positions

Question 9

Circumduction gait deviation with transfemoral prosthetic causes

Answer 9

long prosthesis
locked knee
small or loose socket
inadequate suspension 
foot plantar flexed
abduction contracture
poor knee control

Question 10

abducted gait with transfemoral prosthesis causes

Answer 10

crotch or medial wall discomfort from too high medial wall or sharp medial wall
long prosthesis
low lateral wall or malalignment
tight hip abductors/abduction contracture
instability of hip joint

Question 11

vaulting gait pattern with transfemoral prosthesis causes

Answer 11

prosthesis too long
inadequate suspension
socket too small
prosthetic foot in too much plantarflexion
too little knee flexion
too fast gait speed

Question 12

lateral trunk bending in stance with transfemoral prosthesis causes

Answer 12

low lateral wall
short prosthesis
high or sharp medial wall
weak abductors
abductor contractures
hip pain
short amputation limb

Question 13

forward flexion during stance with transfemoral amputation causes

Answer 13

unstable knee unit
short ambulatory aids
hip flexion contracture

Question 14

lumbar lordosis with transfemoral amputation causes

Answer 14

insufficient support from anterior or posterior walls
painful ischial weight bearing
hip flexion contracture
weak hip extensors or abdominals
inadequate socket flexion

Question 15

high heel rise with transfemoral prosthesis causes

Answer 15

inadequate knee friction

too little tension in extension aid

Question 16

terminal swing impact with transfemoral prosthesis causes

Answer 16

insufficient knee friction
too much tension in extension aid
patient fears knee will buckle
forecfull hip flexion

Question 17

swing phase whip with transfemoral prosthesis causes

Answer 17

socket is rotated
knee bolt is rotated
foot is malaligned
socket donned malaligned

Question 18

foot rotation at heel strike with transfemoral prosthesis causes

Answer 18

foot is malaligned
stiff heel cushion
plantar flexion bumper

Question 19

foot slap with transfemoral prosthesis causes

Answer 19

heel cushion or plantar flexion bumper is too soft

Question 20

uneven step length with transfemoral prosthesis causes

Answer 20

socket discomfort
poor alignment
hip flexion contracture
hip instability

Question 21

excessive knee flexion in stance with transtibial prosthesis causes

Answer 21

socket aligned too far forward 
socket tilted too far anteriorly 
plantar flexion bumper too hard
high heel shoes
knee flexion contracture 
weak quadriceps 
insufficient plantar flexion
stiff heel cushion

Question 22

inadequate knee flexion in stance with transtibial prosthesis causes

Answer 22

socket may be aligned too far back or tilted posteriorly
plantar flexion bumper or heel cushion too soft
low heel shoes
anterodistal discomfort
weak quadriceps
arthritis

Question 23

lateral thrust at midstance transtibial prosthesis causes

Answer 23

foot is inset too much

Question 24

medial thrust at midstance transtibial prosthesis causes

Answer 24

foot is outset too much

Question 25

drop off or premature knee flexion in late stance transtibial prosthesis causes

Answer 25

socket is set too far forward or excessively flexed dorsiflexion bumper too soft resulting in excess DF prosthetic foot keel too short knee flexion contracture

Question 26

delayed knee flexion during late stance transtibial prosthesis causes

Answer 26

socket set too far back or lacks sufficient flexion dorsiflexion bumper too stiff causing excess PF prosthetic foot keel too long
