what are the symptoms of nerve irritation of an ill fitted orthotic CORRECT ANSWERS
numbness
tingling
burning
motor changes
pain
what are the symptoms of vascular irritation of an ill fitted orthotic CORRECT
ANSWERS change in color (deep red, blue, blanched)
temperature changes
swelling
burning
throbbing
how might you modify an orthotic that is causing nerve/vascular irritation symptoms
CORRECT ANSWERS extra padding
flaring the orthotic's edge
use straps and slings of adequate width to disperse the pressure
what are the 3 force principles when creating a biomechanics advantage for an orthotic?
CORRECT ANSWERS 1. at rest, all forces must be balanced and equal 0.
2. increasing the surface area, decreases the local pressure on the skin
3. increasing the moment arm length, decreases the local pressure on the skin
which type of orthosis utilizes low load, long duration stretch with the muscle at/near its
maximum length CORRECT ANSWERS serial static orthosis
which type of orthosis utilizes stress relaxation theory and applies a low load force to
the tissue's end range in one direction over a long period of time CORRECT ANSWERS
static progressive orthosis
what is the stress relaxation theory CORRECT ANSWERS occurs when a material that
is subjected to a constant deformation requires a decreasing load with time to maintain
a steady state --> creep
what is the present day theory on foot orthoses CORRECT ANSWERS tissue stress
theory
what is an outrigger CORRECT ANSWERS an extension from the base of the brace
that allows the force to retain the optimal 90 degree pull
, T/F: a static orthosis with an outrigger becomes a dynamic orthosis CORRECT
ANSWERS true
purpose of adding an outrigger to a static orthosis CORRECT ANSWERS allows for
dynamic stretching
are outriggers typically on UE or LE splints CORRECT ANSWERS UE > LE
what kind of braces use 4 points of contact CORRECT ANSWERS ACL brace
KAFO
which population would benefit from a rocker bottom shoe with flared/cushion heel
CORRECT ANSWERS arthritis
which population would benefit from a rocker bottom shoe with extra depth to allow for
swelling/deformities, with a cushion heel CORRECT ANSWERS gout
which population would benefit from a Thermold leather shoe (which is full contact, soft,
shock absorbing material) CORRECT ANSWERS diabetes
PVD if no edema is present
which population would benefit from a Thermold sandal with velcro closure CORRECT
ANSWERS PVD
which population would benefit from a shoe with elastic shoe laces CORRECT
ANSWERS pts with edema
which population would benefit from a leather flat bottom shoe with mild toe spring
CORRECT ANSWERS PD
when is a locking KAFO indicated CORRECT ANSWERS when AFO does not control
knee buckling, medial/lateral stability or AP stability, or if they have < 3/5 quad strength
describe the difference between bail lock and drop lock KAFOs CORRECT ANSWERS
bail: pressure from the back of their seat to a stiff bar releases the lock to allow for
flexion; spring loaded extension
drop: gravity dependent locking for extension, manually lift lock for flexion
who should not use drop lock KAFOs CORRECT ANSWERS if the pt has limited hand
function, significant LE spasticity, or dependence on an AD when standing
who should utilize drop lock KAFOs CORRECT ANSWERS - pt has hand function
- no spasticity in LE
- no AD
