1. What is the primary purpose of a prosthetic limb?
A. Cosmetic enhancement
B. Pain relief
C. Restore functional mobility
D. Increase muscle mass
Rationale: The main goal of a prosthetic limb is to restore
functional mobility and allow patients to perform daily
activities, not just cosmetic or strength purposes.
2. Which material is most commonly used for lightweight
prosthetic sockets?
A. Stainless steel
B. Carbon fiber
C. Aluminum
D. Wood
,Rationale: Carbon fiber is lightweight, strong, and durable,
making it ideal for prosthetic sockets.
3. What type of orthosis is indicated for a patient with spinal
deformity such as scoliosis?
A. Knee-Ankle-Foot Orthosis (KAFO)
B. Thoracolumbosacral Orthosis (TLSO)
C. Foot Orthosis
D. Cervical collar
Rationale: TLSOs are designed to control spinal alignment and
are commonly used in scoliosis treatment.
4. The primary component of a below-knee prosthesis that
interfaces with the residual limb is called:
A. Pylon
B. Foot
C. Socket
D. Suspension system
Rationale: The socket is custom-molded to the residual limb
and ensures proper fit, comfort, and load distribution.
5. Which of the following is a common gait deviation in
transfemoral prosthesis users?
,A. Antalgic gait
B. Circumduction
C. Trendelenburg gait
D. Equinus gait
Rationale: Circumduction is a compensatory gait pattern
where the prosthetic limb swings outward due to insufficient
knee flexion or excessive socket fit issues.
6. What is the primary function of a KAFO?
A. Reduce hip pain
B. Correct scoliosis
C. Provide knee stability during stance phase
D. Improve ankle dorsiflexion
Rationale: KAFOs provide mechanical stability to the knee and
control limb alignment during weight-bearing.
7. For a transtibial prosthesis, what type of suspension system
uses a sleeve that rolls over the residual limb?
A. Suction
B. Pin-lock
C. Elastic sleeve
D. Vacuum-assisted
, Rationale: Elastic sleeves are used to create a secure fit by
compressing the residual limb and maintaining suspension.
8. What is the main biomechanical purpose of a prosthetic
foot with a flexible keel?
A. Aesthetic appeal
B. Shock absorption only
C. Energy storage and return during gait
D. Limiting ankle motion
Rationale: A flexible keel stores energy during stance and
returns it during push-off, improving gait efficiency.
9. Which of the following is a contraindication for immediate
prosthetic fitting after amputation?
A. Healthy residual limb
B. Active infection or open wounds
C. Stable cardiovascular status
D. Good skin integrity
Rationale: Prosthetic fitting should be delayed until infection is
resolved and wounds are fully healed to prevent
complications.
