QUESTION 1.
A patient with post-polio syndrome demonstrates progressive quadriceps weakness
but retains adequate hip extensor strength. Which orthotic intervention is most
,appropriate to improve stance stability while minimizing unnecessary restriction of
knee motion?
A. Solid ankle-foot orthosis only
B. Knee-ankle-foot orthosis with stance-control knee joint
C. Hinged knee brace without ankle control
D. Elastic knee sleeve
🔴 Correct Answer: B. Knee-ankle-foot orthosis with stance-control knee joint
🔵 Explanation: A stance-control KAFO stabilizes the knee during stance while
allowing knee flexion during swing, improving gait efficiency in patients with adequate
hip control. AFOs alone may not sufficiently control knee collapse, while simple braces
and sleeves do not provide adequate stability for significant quadriceps weakness.
QUESTION 2.
During gait analysis, excessive external foot progression is observed despite
appropriate transverse plane hip motion. Which finding most strongly suggests tibial
torsion as the primary contributor?
A. Symmetric thigh-foot angle within normal limits
B. Increased femoral anteversion on imaging
C. Abnormally increased thigh-foot angle during examination
D. Limited subtalar joint motion alone
🔴 Correct Answer: C. Abnormally increased thigh-foot angle during examination
🔵 Explanation: The thigh-foot angle is a primary clinical measure for tibial torsion.
Femoral anteversion affects proximal rotation rather than isolated tibial alignment,
while subtalar motion alone cannot explain excessive external progression caused by
tibial torsion.
QUESTION 3.
,A rigid ankle-foot orthosis is prescribed primarily to reduce excessive plantarflexion
during initial contact. Which biomechanical effect is most likely?
A. Increased knee hyperextension during loading response
B. Improved heel strike and controlled tibial advancement
C. Increased subtalar inversion throughout stance
D. Increased pelvic rotation during swing
🔴 Correct Answer: B. Improved heel strike and controlled tibial advancement
🔵 Explanation: Restricting excessive plantarflexion promotes heel-first contact and
allows more controlled progression of the tibia over the foot. Hyperextension may occur
if alignment is inappropriate, but it is not the intended biomechanical effect.
QUESTION 4.
Which clinical finding most strongly supports prescribing a custom-molded orthosis
rather than a prefabricated device?
A. Mild intermittent discomfort after recreational walking
B. Flexible pes planus without symptoms
C. Complex multiplanar deformity requiring total-contact control
D. Normal foot alignment with occasional fatigue
🔴 Correct Answer: C. Complex multiplanar deformity requiring total-contact
control
🔵 Explanation: Complex deformities require individualized contouring, pressure
redistribution, and precise corrective forces that are achievable with custom fabrication.
Prefabricated devices generally cannot provide sufficient control for severe multiplanar
deformities.
QUESTION 5.
A patient develops persistent redness over the fibular head after prolonged use of a
KAFO. The most appropriate initial clinical response is to:
, A. Increase wearing time until the skin adapts
B. Add additional straps without assessment
C. Immediately discontinue follow-up visits
D. Evaluate fit, relieve pressure, and reassess alignment
🔴 Correct Answer: D. Evaluate fit, relieve pressure, and reassess alignment
🔵 Explanation: Persistent redness over a bony prominence suggests excessive localized
pressure requiring prompt assessment and modification. Increasing wear time or
ignoring the problem increases the risk of skin breakdown.
QUESTION 6.
Which orthotic principle best explains the effectiveness of a three-point pressure
system?
A. Maximizing friction between skin and orthosis
B. Producing rotational correction through equal parallel forces only
C. Applying one corrective force opposed by two counterforces to control alignment
D. Eliminating all joint movement
🔴 Correct Answer: C. Applying one corrective force opposed by two
counterforces to control alignment
🔵 Explanation: The three-point pressure principle creates a balanced force system that
controls or corrects deformity while minimizing unwanted movement. It is fundamental
to many orthotic designs.
QUESTION 7.
A child with spastic diplegic cerebral palsy demonstrates persistent equinus during
stance. Which orthotic objective is most appropriate?
A. Increase plantarflexion range of motion
B. Promote controlled dorsiflexion and improve knee extension stability
