common with kids

Question 12

posterior leaf spring: lateral support

Answer 12

• doesn’t cover malleoli

- don’t give lateral and medial support

Question 13

Answer 14

neutral

Answer 15

• someone who only has DF issue

- is stable everywhere else

Question 16

Spiral AFO =

Answer 16

toe-off

Question 17

How does a spiral AFO act?

Answer 17

• like a posterior leaf spring

- flexes during loading response to stance to help with toe-off

Question 18

spiral AFO: toe plate

Answer 18

• full

- keeps foot from dropping during swing phase

Question 19

spiral AFO: rockers

Answer 19

• doesn’t give full rocker moments

- not as rigid as others

Question 20

DF assist/PF stop plastic AFO: How would you name this?

Answer 20

• PF stop of neutral
• PF stop of 2˚ DF
• etc.

Question 21

DF assist/PF stop plastic AFO: what does it have?

Answer 21

• adjustable piece allows you to lock foot in DF position

- doesn’t allow PF

Question 22

DF assist/PF stop plastic AFO: foot during swing

Answer 22
