Reading Guide: High-Level LE

Question 1

Basic socket design for high level LE amputee

Answer 1

flexible thermoplastic or silicone within rigid frame is the most comfortable option

Question 2

Most important aspect of socket design for high level amputees

Answer 2

• careful fitting

- secure suspension

Question 3

alignment stability for high-level LE amputee

Answer 3

• same as normal limb

- in midstance, GRF should fall posterior to the hip and anterior to the knee

Question 4

dysvascular pts: How does loss of one limb affect the risk of eventual bilateral limb loss?

Answer 4

up to 50% more likely to lose contralateral limb within 5 years

Question 5

How does energy consumption change for the B LE amputee?

Answer 5

• increased

- especially if they don’t have a biological knee

Question 6

Longer residual limb and energy cost

Answer 6

lower energy cost to walk with prosthesis

Question 7

How does rehab change for the B LE pt?

Answer 7

• similar to single limb amputation

- occurs in phases

Question 8

phases of rehab for B LE amputee

Answer 8

• preoperative (time permitting)
• immediate postoperative
• acute rehab

Question 9

How does gait change for the B LE pt?

Answer 9

• 2 artificial limbs are more difficult

- walk slowly and cautiously

Question 10

What does gait look like for a B LE pt?

Answer 10

• wide BOS to maximize stability
• shorter step length
• slower speed/cadence
• hip hiking in swing

Question 11

What are stubbies?

Answer 11

shortened pair of prostheses used for early gait training

Question 12

Who are stubbies used with?

Answer 12

B traumatic TF amputation

Question 13

What are the advantages of using stubbies?

Answer 13

• can develop postural control without having to worry about stability of prosthetic knee units
• require less energy and balance

gives the best chance for successful amputation
