L9 Amputee Gait Flashcards

Question

TF Knee instability at IC

Answer 1

high heel height excessive DF too far ant knee inadequate socket flexion prosthesis too long hip flexion contracture weak hip extensors

Answer 2

pf resistance is too soft heel lever is too short heel cushion is too soft pt grinding heel into ground

Answer 3

Foot bumper too firm loose socket foot aligned in ER poor muscular control weakness of hip muscles not enough WB at IC

Answer 4

socket too big poor suspension knee instability knee axis too far anterior hip flexion contracture weak hip extensors pain with ischial WB

Answer 5

lateral wall of socket has space prosthesis too long high medial wall prosthesis aligned in abduction weakness abduction contracture adductor roll reduced balance pain on ramus lack of confidence

Answer 6

prosthesis too short space within socket medial wall of socket is too high inadequate socket adduction prosthesis in abduction pain on ramus pain of lateral distal femur short residual limb weak hip abductors poor balance

Answer 7

insufficient socket flexion ppor shaping of post wall of prosthesis flexion contracture weak hip ext weak abd pain on ischial WB

Answer 8

occurs when heel travels medially at beginning of swing phase prosthetic knee ER, socket donned in ER, inadequate suspension

Answer 9

heel moves laterally at IC prosthetic knee IR, socket donned in IR, inadequate suspension

Answer 10

excessive PF positioning decreased knee flex lack of weight shift weak hip flex lack of confidence socket posterior increased pf

Answer 11

excessive mechanical resistance to knee flex prosthesis alignment too stable prosthesis too long excessive pf inadequate suspension lack of training fear of catching toe during swing fear of knee flexion weakness of hip flexors for swing

Answer 12

keep weight through prosthetic leg and push weight down through the heel as they sit

Answer 13

move prosthetic foot slightly behind to get toe load to unlock the knee

Answer 14

use of hip flexors initiation of forward pelvic rotation timing of heel rise controlled shifting of weight from prosthesis to intact side

Answer 15

locked for both swing and stance stable, doesn't allow for normal gait swing is done through hip hike/circumduction shorter prosthesis, causes lateral trunk lean

Answer 16

free moving hinge from flexion to extension knee stability is acheived based on GRF GRF should be ant to knee in stance focus on heel strike and strong hip ext knee doesn't allow for change in speed

Answer 17

mechanical friction during stance free swing when its not WB has a risk for buckling practice weight shift off and hip ext knee doesn't allow for change in speed

Answer 18

very stable need to practice heel strike with strong hip ext for stability need to practice weight shift for swing

Answer 19

can rapidly adapt to changes in gait, including cadence or incline

Answer 20

progress to activities that demand varied cadence and transitional gait liked sidestepping, turning practice dynamic gait activities like crossing the street

Answer 21

step over step requires quads and med to long residual limb the more limited df, the harder it is to go up

Answer 22

toes of prosthetic foot hang over edge of step to allow knee to bend

Answer 23

technique varies on knee usually step to pattern leading with intact should practice weight shift and stabilization with hip extensors, hip abductors most likely will need to abduct prosthetic limb to avoid toes catching

Answer 24

step to pattern leading with prosthetic can do step over step depending on knee. Should place heel only on step to create flexion at knee. C-leg is best for this side-stepping can also be used

Answer 25

step to pattern to allow hip extension avoid DF limit by ER the foot and roll over instep steep hills require side stepping or figure S

Answer 26

safest is to lead with prosthetic side and take short step with sound side sidestepping can be used, leading with prosthetic
