Non-Systems Flashcards
Purpose of crutches
Increase BOS, provide stability and transfer of weight from lower body to upper body
ex. NWB, partial WB, toe touch
Which nerve is most affected by long term or inappropriate use of crutches
radial nerve
Purpose of cane
widen BOS, decrease antalgic gait pattern
Advantage/disadvantage of quad cane
slows gait pattern but provides more stability
SMQC fits better on stairs
LBQC does not
Which artery is most affected by long term or inappropriate use of crutches
Axillary artery
Flexible AFO
provides DF
poor stabilization of subtalar joint
Warranted use for flexible AFO
foot drop
Warranted use for rigid AFO
preventing varus/valgus
complete loss of DF strength
Purpose of posterior leaf spring AFO
helps with weak dorsiflexors
Downside with posterior leaf spring AFO
thin, low profile, but no medial/lateral stability
Purpose of plantar flexion stop AFO
To control PF spasticity or contracture, knee hyperextension
Plantar flexion stop AFO is typically set to
90 degrees
Purpose of DF stop AFO
Compensates for weak gastroc/soleus/quads
Assists with push-off
Assists the knee joint into extension
Plantar flexion stop AFO is typically set to
5 degrees
RGO
ipsilateral hip flexion produces contralateral hip extension via cable system
RGO is used primarily with what level SCI
T12-L3
Purpose of GRAFO
places the foot in slight PF so that initial contact is with the forefoot (hence GRF anterior to the knee), the horizontal knee component of the GRAFO pushes the knee posteriorly to prevent buckling
Patient population where GRAFO is commonly used
CP - crouch gait - pushes knee back into extension to prevent buckling
Post polio - quad paralysis
Metatarsal bar
bar of leather or foam placed proximal to met heads
used to relieve pressure off met heads
Rocker bottom
builds up sole behind met heads, creating “banana sole”
used to redistribute pressure and improve push off
Who is someone who would benefit from a rocker bottom shoe
Tight PF
Stiff ankle
Why does forefoot varus create excess pronation
When the foot is ridgid into varus, the first MTP joint has to come down much further, creating a genu valgum at the knee and excess pronation
Wedge used for forefoot varus
Medial wedge - to control excessive pronation
Wedge used for forefoot valgus
lateral wedge
