Radial nerve is injured within the radial groove, which muscles
would be paralyzed? - correct answer - Supinator
Brachioradialis
Extensor carpi ulnaris - all muscles in the posterior compartment
will be paralyzed, leading to wrist drop
When turning a conventional AFO into a dorsiflexion assist AFO,
how would you set up the double action joints? - correct answer -
Springs in the posterior channels will produce dorsiflexion assist
A patient with flaccid dorsiflexors and plantarflexors would benefit
from what double action joint AFO configuration? - correct answer
- Pins in the anterior and posterior channels
, Page | 2
Claw hand presentation is due to injury to what nerve? - correct
answer - Ulnar nerve - damage commonly occurs where it passes
posterior to the medial epicondyle on the humerus. The patient is
likely to have difficulty making a fist due to the paralysis of the
intrinsic muscles of the hand. Clawhand comes from inability to
flex the 4th and 5th MCP joint
A patient has flaccid plantarflexors and dorsiflexors, also with
buckling at the knee during loading response/heel strike. What
would be the most appropriate configuration of the double action
ankle joints? - correct answer - Springs in the posterior channels
and pins in the anterior channels - provides adequate
anterior/posterior support to the lower leg muscular imbalances
but the posterior springs will allow controlled plantarflexion during
loading response whereby keeping the GRF anterior to the knee
joint to decrease knee buckling
A patient with Duchennes Muscular Dystrophy is seen to
ambulate with increased lumbar lordosis secondary to which
muscular weakness? - correct answer - Hip extensors - increasing
lumbar lordosis moves the COM posterior to the hip joint, which
locks the hip against the y-ligament allowing for stability in the
sagittal plane

A patient sustains a Hangman's fracture. This fracture can cause
quadriplegia. What vertebrae and location of the fracture is
damaged? - correct answer - Atlas, lamina (pars interarticularis)
C2 - hangman's is a fracture through the lamina of the axis.
ANother injury to the axis is displacement of the dens, which may
also cause quadriplegia
When designing a thermoplastic KAFO for a patient with severe
genu recurvatum, what can you incorporate that will help control
the knee hyperextension? - correct answer - Extending the
distal/posterior thigh trim line more distally
Decreasing the depth of the thigh section
Extending the proximal/posterior calf trim line proximally
Decreasing the depth of the calf section
A patient with a KAFO complains of anterior thigh pressure when
sitting. What could be the cause? - correct answer - Mechanical
knee joint is too distal in relation to the anatomical joint
The erector spinae muscles are found in the intermediate layer of
the muscles in the back. When they act bilaterally, they extend
the vertebral column. When they act unilaterally what action do
they perform? - correct answer - Laterally bend the vertebral
column

A child wearing a Pavlik harness in treatment for congenital
dislocation of the hips should have their hips oriented in: - correct
answer - Flexion and abduction
A 240lb female bears how much weight collectively through her
right 2nd-5th MTP joints while standing evenly on both feet? -
correct answer - 40 lbs - 240/2 = 120lb/foot; 50% goes to
calcaneus and 50% to the MTP (60lbs); 2nd-5th MTP receive
66.6% (40lbs)
The axillary nerve innervates what two muscles? - correct answer
- Teres minor
Deltoid
Guillain-Barre syndrome progresses in ascending or descending
order? - correct answer - Ascending - distal to proximal and
recovers in descending order of proximal to distal
A child playing on the floor and proceeds to use his hands to
stand up by pushing off his lower extremities until upright. What is
