AFO Design

Question 1

Draw the trim lines that define a UCBL insert. Explain the biomechanical principles.

Answer 1

-

Question 2

Draw the trim lines and indicate any necessary components for a GRAFO. Explain the biomechanical principles.

Answer 2

anterior: bottom edge is 5” below distal edge of patella
posterior: 1” below anterior
ML opening wide enough for malleoli to pass through

Question 3

Draw the trim lines and indicate any necessary components for an AFO to provide toe clearance during swing phase. Explain any biomechanical principles.

Answer 3

pls? posterior to malleoli

allows for some movement but will keep 90 during swing

Question 4

Proximal trim line AFO

Answer 4

1.5” distal to head of fibula to prevent pressure on peroneal nerve
foot plate alone apices of met heads
