oral exam Flashcards
metal solid ankle conditions
- significantly decreased strength in anterior and posterior musculature
- pain at ankle
- knee buckling
- knee hyperextension
- foot drop
metal limited motion conditions
- decreased strength in anterior or posterior musculature - amount of motion allowed impacted by amount of strength
- pain at ankle
- foot drop
PF stop conditions
- decreased strength in anterior musculature
- foot drop
DF stop conditions
- decreased strength in posterior musculature
- knee buckling
DF assist conditions
- decreased anterior musculature strength in the presence of strong posterior musculature strength
- DF weakness
PF assist conditions
- decreased posterior musculature strength in the presence of strong anterior musculature strength
- PF weakness
free motion conditions
- decreased eversion or inversion strength
- pain at ankle
DF stop, PF stop, DF assist conditions
- significantly decreased strength in anterior or posterior musculature
- foot drop
- knee buckling
KAFO with solid ankle conditions
significantly decreased/absent strength in anterior and posterior musculature at ankle and knee
plastic solid conditions
knee buckling and foot drop
plastic rigid conditions
foot drop and knee hyperextension
plastic semi-rigid conditions
foot drop and may assist with inversion/eversion
plastic flexible/posterior leaf spring
foot drop and maintains neutral foot during swing
articulating conditions
foot drop and depending on PF stop may impact knee hyperextension
extended toe plate used for
tow clawing or spasticity
drop lock
locks automatically at full extension, simple and secure
bail lock
- allows knee flexion
- used for bilateral patients, people with dexterity/balance concerns
t strap used for
- added to limit hindfoot movement in frontal plane
- inversion/eversion
wedge uses
when patient has a PF contracture
when to choose a metal orthotic
for interim management, swelling, poor sensation, poor skin quality
advantages of plastic orthotic
light weight, improved control through foot
