Lower Extremity Orthotics Flashcards
1
Q
What is a PRAFO and what is it indicated for?
A
Pressure Relieving Ankle Foot Orthosis
-for contracture prevention and pressure relief (neuro involvement, ortho, long term immobilization)
2
Q
Principle behind foot orthotic
A
3 point pressure system
3
Q
Where are trim lines located?
A
proximal, anterior, ankle, foot, metatarsal
4
Q
What is part of your evaluation?
A
functional ROM (midtarsal, subtalar, talocrural, knee and hip) -functional muscle strength ( focus on general muscle groups)
5
Q
Foundation of any orthotic
A
shoes
6
Q
Prefabricated LE orthotics
A
- “off the shelf”
- limited fit and function
- mild involvement
- temporary use
- diagnostic procedures
7
Q
Custom fit LE orthotics
A
- prefabricated device that is modified to fit a specific patient
- provide limited fit and functional
- mild to moderate involvement
- temporary use
- diagnostic procedures
8
Q
Custom fabricated LE orthotics
A
- individualized fit for maximal function
- moderate to severe involvement
- extended or permanent use
9
Q
What do custom fabricated braces involve?

- fabrication
- modification
10
Q
Supramalleolar foot orthosis (SMO, DAFO)
- allows ____
- Provides ______
- ____ management
A
- dorsiflexion and plantarflexion
- forefoot, midfoot and subtalar stability
- tone
11
Q
Ground reaction AFO
A
- pre-tibial cuff facilitates knee extension
- rigid foot plate facilitates push-off
- capable of tri-planar motion control
12
Q
Patellar tendon bearing AFO
A
reduces force on mid-foot and heel
13
Q
Solid ankle AFO
A
- trim lines encompass malleoli
- maximum motion control in all planes
14
Q
Semi-solid AFO
A
trim lines bisect malleoli
- allows some dorsiflexion in late stance
- provides some M-L stabilization
15
Q
Posterior Leaf Spring AFO
A
- stores energy in loading
- releases energy to facilitate swing
- provides little M-L stability
