Which AFO is most appropriate for a patient with ankle instability and no DF? - answer
Solid AFO
T/F: To restore the biomechanics advantage of a dislocated PIP joint the best stress to
use is compression. - answer True
T/F: A dynamic hand splint would best help improve passive range of motion in a
patient's hand with hypertonicity - answer True
T/F: Burning is a sign of a nerve irritation in an ill fitting orthoses - answer True
Static orthoses hold a body segment at rest through rigid supports. Negative effects of
these can include - answer Both muscle atrophy and tightness

AFO. - answer True
A KAFO is indicated when - answer
In order to be considered for a SCKAFO a patient must have - answerMMT of at least
3/5 for hip flexors
T/F: A bioness or walk aide is an example of a myoelectric device. - answerTrue
T/F: Heel rocker, ankle rocker and foot rocker all describe phases of gait. - answerTrue
T/F: The most stable cervical orthoses is the Halo. - answerTrue
An AFO set in slight plantarflexion will - answerIncrease knee extension in stance or
heel rocker for a knee that buckles
An AFO that is set in slight dorsiflexion will - answerDecrease knee hyperextension in
stance phase
If a patient presents with mild spasticity of the plantarflexion and toe drag, the AFO
should be set in - answerSlight DF
, Most orthoses employ what type of level? - answerFirst Class Lever
For a patient who presents with clonus, what orthosis should be considered? -
answerAn articulating AFO with PF or DF stop to decrease clonus at rest but allow for
movement
What type of orthosis is utilized to hold the ankle in a few degrees of PF so the tibia
doesn't roll over the ankle? - answerFloor Reaction AFO
What type of orthosis is used when there is no anterior compartment muscle function? -
answerCarbon Fiber AFO
What type of orthosis does not provide medial/lateral support like the Posterior Spring
Leaf, can provide dynamic spring assist, and has been shown to enhance gastroc
strength? - answerCarbon Fiber AFO
What type of orthosis has little medial/lateral support, but supports the weight of the foot
during swing phase? - answerPosterior Spring Leaf
Why are forces distributed over large surfaces? - answerTo decrease pressure on the
skin
The sum of the primary force and counter force will always be - answerZero
What type of movement arm will decrease the amount of force to control a joint? -
answerLarge Movement Arm
What type of cervical orthosis is the least stable? - answerSoft Collar
What is the only difference between the Philadelphia and Miami J? - answerThe Miami
J has more plastic on it which makes it slightly more stable
What are the biggest signs of nerve irritation with orthotic use? - answerBurning and
tingling
A patient wearing an orthosis experiencing burning is the result of - answerEdema or an
orthoses that is fitting too tight
Cold and color changes are indicative of - answerVascular Irritations
If a hand patient's goal is to improve passive range of motion, what type of splint should
be used? - answerA dynamic splint
Does a solid thermoplastic AFO accommodate for edema? - answerNo
