Transfemoral Gait

Question 1

What is their gait cycle like?

Answer 1

• shorter
• more time in double limb support
• upright trunk
• core stabilization

Question 2

What is important in loading response?

Answer 2

knee joint stability

Question 3

What may be the patient cause for forceful and excessive knee extension during terminal impact?

Answer 3

• afraid of knee giving away

- forceful hip flexion

Question 4

What may be the patient cause of foot slap?

Answer 4

increased hip extension force at initial contact

Question 5

What may be the prosthetic cause of knee instability in stance?

Answer 5

• knee axis too far anterior (causes posterior or flexor moment)
• socket too far posterior
• lack of socket flexion

Question 6

What may be the patient cause of knee instability in stance?

Answer 6

• inadequate hip extension ROM

- Hip flexion contracture

Question 7

What may be prosthetic causes to a lateral trunk bend in midstance?

Answer 7

• socket too abducted
• prosthesis too short
• medial socket wall too high

Question 8

What may be patient causes to a lateral trunk bend in midstance?

Answer 8

• pain
• glute med weakness
• decreased balance
• adductor roll

Question 9

What may be the prosthetic cause of an abducted gait in midstance?

Answer 9

• foot/leg too far outset
• prosthesis too long (patient will want to get pressure off medial wall)
• medial socket wall too high
• lateral wall not adducted enough (causes OKC before getting CKC)

Question 10

What may be the patient cause of an abducted gait in midstance?

Answer 10

• abduction contracture
• lateral-distal residual limb pain
• decreased balance/trying to increase their BoS
• Adductor roll

Question 11

What may be the prosthetic cause to excessive trunk extension in midstance?

Answer 11

• increased socket extension

- not enough flexion built into the socket

Question 12

What may be the patient cause to excessive trunk extension in midstance? What position will the patient be in?

Answer 12

• weak hip extensors
• weak abdominals
• hip flexion contracture
• very short residual limb

Patient will be in a hyperlordodic position

Question 13

What is drop off? What phase does it occur in?

Answer 13

sudden and excessive knee flexion during late stance phase

Question 14

What may be the prosthetic cause of drop off in terminal stance?

Answer 14

• short toe lever

- socket set too far posterior to knee axis

Question 15

What may be the patient cause for excessive heel raise during swing phase?

Answer 15

forceful hip flexion

Question 16

What may be the prosthetic cause to circumduction during swing phase?

Answer 16

• prosthesis too long
• inadequate suspension (pistoning)
• excessive knee friction

Question 17

What may be the patient cause to circumduction during swing phase?

Answer 17

• hip flexor weakness
• hip abduction contracture
• fear

Question 18

What may be the prosthetic cause to vaulting during swing phase?

Answer 18

• prosthesis too long
• inadequate suspension
• excessive knee friction

Question 19

What may be the patient cause to vaulting during swing phase?

Answer 19

• hip flexor weakness
• hip abduction contracture
• fear

Question 20

What may be the prosthetic issue for medial whip during swing phase?

Answer 20

• ER of knee component

- improper alignment of knee bolt

Question 21

What may be the patient issue for medial whip during swing phase?

Answer 21

improper donning

Question 22

What may be the prosthetic issue for lateral whip during swing phase?

Answer 22

• IR of knee component

- improper alignment of knee bolt

Question 23

What may be the patient issue for lateral whip during swing phase?

Answer 23

improper donning
