ABC PROSTHETIC FINAL TEST 2026
QUESTIONS WITH CORRECT ANSWERS
GRADED A+
◍ What is the correction for medial whip in swing phase?.
Answer: Internally rotate socket.
◍ How does increasing contact area affect pressure?.
Answer: Increasing contact area decreases pressure.
◍ What does SEWHO stand for and when is it used?.
Answer: Shoulder-Elbow-Wrist-Hand orthosis, used post-trauma or for
brachial plexus injuries.
◍ What is the function of an Arm trough/lapboard in a wheelchair?.
Answer: To manage glenohumeral subluxation without forcing internal
rotation/adduction.
◍ What are the tolerant areas of a TT socket?.
Answer: Supracondylar & Suprapatellar areas, Patellar Tendon,
Medial/Lateral Flare of Tibia, Lateral Flare of Fibula, Posterior Soft Tissue,
Popliteal Area.
◍ What is the formula for pressure in biomechanics?.
Answer: Pressure = Force ÷ Area (P = F/A)
◍ What is the function of a Drop Ring Lock in KAFOs?.
Answer: A simple gravity lock that requires hand to unlock.
◍ What is the primary risk factor for ulceration in diabetic foot care?.
Answer: Loss of protective sensation (LOPS).
◍ What is the primary purpose of the AMP (Amputee Mobility Predictor)?.
Answer: To predict K-level and assess mobility capabilities.
, ◍ What type of prosthesis is a Transradial (BEA)?.
Answer: A prosthesis that uses one cable for the terminal device.
◍ What is the purpose of spinal orthoses?.
Answer: To restrict motion and provide support to the spine.
◍ What is the '40/60' rule in prosthetic training?.
Answer: 60% of weight should be through the prosthetic limb during
stability training.
◍ What is the function of a TLSO?.
Answer: Limits flexion and provides support to the thoracolumbar spine.
◍ What is the best prosthesis for a transradial amputee needing durability for
farming?.
Answer: C. Body-Powered Hook.
◍ What is the Figure-8 harness used for?.
Answer: It is a standard harness for both transradial and transhumeral
prostheses.
◍ What correction should be made for knee hyperextension in early stance?.
Answer: Stiffen heel bumper or adjust socket over foot.
◍ What type of shoe last accommodates hallux valgus?.
Answer: Inflare last.
◍ When is an Elbow Orthosis indicated?.
Answer: For post-operative care or spasticity management.
◍ What is the purpose of a toe filler in orthotics?.
Answer: Used after transmetatarsal or digital amputations.
◍ What is the primary function of compression in orthotics?.
Answer: Compression reduces edema or provides uniform pressure.
◍ What is the optimal angle for the line of pull in dynamic orthoses?.
Answer: 90° line of pull maximizes torque and minimizes shear.
