Prosthetics & Orthotics 1 Exam
1.
Which of the following plastics is commonly used as a
topcover?
o A.
Plastizote
o B.
Polyethylene
o C.
Orfilite
o D.
Ppt
Correct Answer
D. Ppt
Explanation
PPT, or Polypropylene Terephthalate, is commonly used as a topcover in
various applications. It is a type of plastic that offers excellent strength,
durability, and resistance to chemicals and heat. PPT is often used as a
protective layer or cover due to its ability to withstand wear and tear, making it
a suitable choice for applications where a strong and long-lasting topcover is
required.

The clinical application that allows a material to return to its
original shape easier than it took for original application is
known as:
o A.
, Creep
o B.
Viscoelasticity
o C.
Malleability
o D.
Hysteresis
Correct Answer
D. Hysteresis Explanation
Hysteresis refers to the phenomenon where a material exhibits a lag or delay in
its response to an applied force or stress. In the context of the given question,
hysteresis is the correct answer because it describes the property of a material
to return to its original shape more easily than it took for the original
application of force or stress. This means that the material retains some
memory of its previous shape and requires less energy to revert back to it.
Creep, viscoelasticity, and malleability are not suitable explanations as they do
not specifically address this property of easy return to original shape.

You are seeing a patient with an uncompensated forefoot
varus. Of the following, which would be appropriate?
o A.
Soft; medial post
o B.
Soft; lateral post
o C.
, Rigid; medial post
o D.
Rigid: lateral post
Correct Answer
A. Soft; medial post
Explanation
In a patient with an uncompensated forefoot varus, the appropriate option
would be to provide a soft orthotic with a medial post. This is because a medial
post helps to support and stabilize the foot, correcting the varus alignment. A
soft orthotic is preferred in this case as it provides cushioning and comfort,
while still offering the necessary support. Using a lateral post or a rigid
orthotic may not effectively address the varus deformity and may cause
discomfort or further alignment issues.

You are seeing a patient who has a compensated rearfoot
varus. Which would be appropriate?
o A.
Rigid, medial post
o B.
Rigid, lateral post
o C.
Soft, medial post
o D.
Soft, lateral post
Correct Answer
A. Rigid, medial post
