QUESTIONS || WITH ERRORLESS
SOLUTIONS 100%.
Question : Which muscle group is most likely affected if you
observe a patient with a shortened step on the sound side (assuming the patient is unilaterally involved)?
Correct answer: plantarflexors
Question : What type of AFO would you use for a patient with a
tibial nerve lesion?
Correct answer: Plantarflexion free, dorsiflexion stop
Question : Evaluation of a patient with a gunshot wound to the
hip reveals weak hip flexors. What peripheral nerve is injured?
Correct answer: femoral nerve
Question : A patient exhibits hallux rigidus, at which part of
stance phase will the patient have the most discomfort?
Correct answer: Late stance phase
Question : What does the term foot progression angle refer to?
- | Page
Correct answer: Relationship between line of progression and
long axis of foot
Question : At which joint and in which plane does the motion of
inversion and eversion occur?
Correct answer: Subtalar (or talocalcaneonavicular) joint,
coronal plane
Question : What motion and at what phase of gait does a
cushioned heel simulate?
Correct answer: plantarflexion at heel strike, initial contact
Question : Injury to which nerve presents as paralytic equinus
during swing phase?
Correct answer: common peroneal nerve

Question : If the ankle is in 3 degrees of plantarflexion at
midstance, what type of moment do you have at the knee?
Correct answer: knee extension moment
Question : During which phase of gait does the ankle achieve
the greatest amount of dorsiflexion in a healthy individual which normal ROM and muscle functionality?
Correct answer: terminal stance
Question : Which ligament maintains the medial arch?
Correct answer: spring ligament (plantarcalcanealnavicular
ligament)

limb support?
Correct answer: 20%

Question : The functions of the tibialis anterior muscles are?
Correct answer: dorsiflexion and inversion
Question : What moment at the knee is created in stance phase
of gait in a solid thermoplastic AFO set to neutral with a rigid full length footplate? Additionally, where in stance would be this most noticed by the patient?
Correct answer: increase the knee extension moment, terminal
stance
Question : Decrease the alignment at the ankle, knee and hips
for crouch gait pattern?
Correct answer: flexed hips, flexed knees, dorsiflexed ankles
Question : A single gait cycle defined as?
Correct answer: Heel strike on one side to heel strike on the
ipsilateral side
