ORTHOTICS CPM EXAMS STUDY BUNDLE 2026
FINAL REVIEW BUNDLED SOLUTION PACKAGE
◉ What type of AFO would you use for a patient with a tibial nerve
lesion? Answer: Plantarflexion free, dorsiflexion stop
◉ Evaluation of a patient with a gunshot wound to the hip reveals weak
hip flexors. What peripheral nerve is injured? Answer: femoral nerve
◉ A patient exhibits hallux rigidus, at which part of stance phase will the
patient have the most discomfort? Answer: Late stance phase
◉ What does the term foot progression angle refer to? Answer:
Relationship between line of progression and long axis of foot
◉ At which joint and in which plane does the motion of inversion and
eversion occur? Answer: Subtalar (or talocalcaneonavicular) joint,
coronal plane
◉ What motion and at what phase of gait does a cushioned heel
simulate? Answer: plantarflexion at heel strike, initial contact
◉ Injury to which nerve presents as paralytic equinus during swing
phase? Answer: common peroneal nerve
,◉ If the ankle is 90 degrees at initial contact, what type of moment do
you have at the knee? Answer: Knee flexion moment
◉ If the ankle is in 3 degrees of plantarflexion at midstance, what type
of moment do you have at the knee? Answer: knee extension moment
◉ During which phase of gait does the ankle achieve the greatest
amount of dorsiflexion in a healthy individual which normal ROM and
muscle functionality? Answer: terminal stance
◉ Which ligament maintains the medial arch? Answer: spring ligament
(plantarcalcanealnavicular ligament)
◉ What percentage of the gait cycle is spent in double limb support?
Answer: 20%
◉ The dorsiflexion stop performs the function of which muscle?
Answer: gastricnemius/soleus
◉ The functions of the tibialis anterior muscles are? Answer:
dorsiflexion and inversion
◉ 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?
Answer: increase the knee extension moment, terminal stance
◉ Decrease the alignment at the ankle, knee and hips for crouch gait
pattern? Answer: flexed hips, flexed knees, dorsiflexed ankles
◉ A single gait cycle defined as? Answer: Heel strike on one side to heel
strike on the ipsilateral side
◉ For which diagnoses would you recommend a rocker bottom shoe?
Answer: diabetes, arthritis, ankle fusion, etc. Whenever a patient
requires a solid AFO
◉ How can you prevent a knee orthosis from migrating down? Answer:
Supracondylar wedge, suprapatellar strap, attach a footplate, lightweight
belt
◉ What is the best position for a patient to be in when being fitted with
a tibial fracture orthosis? Answer: sitting with legs dangling, knees at 90
degrees
◉ What adjustment to a metal AFO would best accommodate excessive
tibial torsion? Answer: deflection of sidebars
