1. An orthosis intended to limit motion at a joint primarily functions to:
A. Increase muscle strength
B. Provide stability and restrict unwanted motion
C. Enhance sensory feedback
D. Improve cardiovascular endurance
The primary purpose of a joint-control orthosis is to stabilize and
restrict unwanted motion to protect tissues and promote proper
biomechanics.
2. A transtibial prosthesis with an excessively posteriorly placed foot will
most likely cause:
A. Increased knee flexion during stance
B. Knee instability in early stance
C. Improved energy return
D. Enhanced ground clearance
A posteriorly positioned foot shifts the ground reaction force behind
the knee, leading to potential instability in early stance.
3. The primary material property of polypropylene that makes it useful
for orthotic fabrication is its:
A. High density
B. Thermoplasticity
C. Brittleness
D. Porosity
, Polypropylene’s ability to soften with heat and be molded makes it
ideal for custom orthotic devices.
4. A K-level of 2 in prosthetic functional classification indicates that the
individual:
A. Is non-ambulatory
B. Can run and jump
C. Ambulates at a household pace with some community mobility
D. Moves only with a wheelchair
K-level 2 describes limited community ambulator status with the
ability to traverse low-level environmental barriers.
5. For a patient with a transfemoral amputation, the socket design that
improves ML stability is the:
A. Ischial containment socket
B. Quadrilateral socket
C. Narrow mediolateral width with wider AP dimension
D. Supracondylar socket
Narrowing the mediolateral width increases stability by better
capturing the residual limb contours and controlling femoral motion.
6. The main biomechanical goal of a UCBL (University of California
Biomechanics Laboratory) orthosis is to:
A. Increase ankle plantarflexion
B. Control subtalar joint motion
C. Enhance knee flexion
D. Promote hip abduction
A UCBL orthosis stabilizes the hindfoot by controlling excessive
subtalar pronation or supination.
7. Which of the following components in a prosthetic foot provides
energy return during gait?
A. SACH heel
B. Solid ankle
C. Dynamic response keel
D. Single axis ankle
A dynamic response keel stores and releases energy during gait,
aiding in propulsion.
, 8. A patient wearing an AFO complains of excessive pressure over the
tibial crest. The most likely cause is:
A. Excessive plantarflexion stop
B. Poor trimline height and contour
C. Too much dorsiflexion assist
D. Incorrect shoe size
Improper trimlines and contouring can create pressure points at bony
prominences such as the tibial crest.
9. The primary purpose of a proximal containment in a transfemoral
prosthetic socket is to:
A. Improve comfort
B. Enhance rotational control
C. Reduce weight
D. Increase knee flexion
Proximal containment provides better control of the femur,
improving rotational stability and overall gait.
10. A Charcot restraint orthotic walker primarily treats:
A. Achilles tendonitis
B. Charcot arthropathy
C. Plantar fasciitis
D. Tibial stress fracture
A CROW walker stabilizes and redistributes load in severe
neuropathic foot conditions like Charcot arthropathy.
11. The function of a double-upright conventional knee ankle foot
orthosis (KAFO) is to:
A. Allow free knee motion
B. Provide maximum knee stability
C. Prevent hip flexion
D. Promote gait speed
Double uprights and knee locks offer rigid support for unstable knees
requiring maximum stability.
12. Which alignment change will increase the external knee flexion
moment in a transtibial prosthesis?
A. Move foot anterior
B. Increase socket flexion
