Prosthetic Written Exam Part 1 – Q’s And A’sTo check prosthesis height the amputee should:
a. support his weight on his sound leg
b. support his weight on his prosthetic leg
c. support his weight equally on both legs
d. not be wearing his prosthesis Correct Ans - c. support his weight
equally on both legs
when walking, the normal foot should pass close to the AK prosthetic foot:
a. to facilitate shift of body weight
b. to prevent hip flexion contractures
c. to strengthen the gluteus medius muscle
d. to decrease pressure on the lateral socket wall Correct Ans - a. to
facilitate shift of body weight
Rotation of the foot at heel strike may be caused by:
a. a stiff dorsiflexion bumper
b. a stiff plantarflexion bumper
c. external rotation of ankle axis
d. internal rotation of knee axis Correct Ans - b. a stiff plantarflexion
bumper
If the ischial tuberosity is placed too far toward the medial side of the ischial
seat, it results in:
a. crowding of adductor muscles into small area, causing burning sensation
b. too musch weight being borne on the ramus of the ischium
c. wedging of stump in the gluteus channel
d. walking with leg internally rotated. Correct Ans - a. crowding of
adductor muscles into small area, causing burning sensation
the knee bolt of the prosthesis is usually found to be
a. perpendicular to the line of progression
b. in approximately 5 degrees of internal rotation
c. in approximately 5 degrees of external rotation
d. in approximately 8 degrees of external rotation Correct Ans - c. in
approximately 5 degrees of external rotation
,when adductor longus tightness is observed during initial fitting the AK socket
you would
a. relieve the socket laterally
b. roll and relieve medial posterior wall
c. flare and contour anterior-medial corner
d. increase flare above ischial level Correct Ans - c. flare and contour
anterior-medial corner
when the above knee amputee must arch his back to maintain the center of
gravity of his body in the proper position while pressing back with his stump,
it is an indication that the:
a. amputee has a pronounced lumbar lordosis
b. foot on prosthesis is located too far laterally
c. stump was fitted into a socket without adequate initial flexion
d. stump was fitted into a socket with excessive abduction Correct Ans -
c. stump was fitted into a socket without adequate initial flexion
As the AK amputee places his weight on the prosthesis the femur presses
toward the lateral wall. Because of this the lateral socket wall should be:
a. rounded to distribute pressure evenly
b. adducted to stabilize the femur during locomotion
c. padded to keep from injuring the stump
d. abducted to allow the end of the femur to move freely Correct Ans -
b. adducted to stabilize the femur during locomotion
the suction socket prosthesis is aligned so that involuntary alignment stability
is minimized and voluntary knee control by stump action is emphasized:
A. in order that a minimum amount of energy is consumed during walking.
b. to provide valuable exercise for stump muscles
c. to make it possible to use a simplified knee mechanism
d. in order that the cosmetic appearance of the limb is improved. Correct
Ans - A. in order that a minimum amount of energy is consumed during
walking.
If a force of 10 lbs exerted on the five foot arm of a lever, what force must be
exerted on the five foot arm to balance it?
a. 25 lbs
b. 50 lbs
c. 20 lbs
, d. 30 lbs Correct Ans - a. 25 lbs
medial whip is caused by:
a. improper placement of the toe break
b. external rotation of ankle axis
c. medial rotation of knee bolt
d. excessive lateral rotation of knee bolt Correct Ans - d. excessive
lateral rotation of knee bolt
In correcting an abducted socket on the adjustable leg, we should:
a. release the medial tilt screw and tighten the lateral
b. release the lateral tilt screw and tighten the medial
c. release the lateral locking adjustment and move the shank medially
d. give the amputee a wider walking base Correct Ans - a. release the
medial tilt screw and tighten the lateral
when pulling the amputee into an ak socket the most important anatomical
landmark is:
a. gluteus maximus muscle
b. hamstring muscle group
c. adductor longus tendon
d. rectus femoris tendon Correct Ans - c. adductor longus tendon
if the ischial seat of the ak socket is made too wide, it will cause:
a. painful spasm of the gluteus maximus
b. excessive pressure on the hamstring muscles, resulting in stump edema
c. burning sensation when the wearer is seated, because of excessive
stretching of the skin
d. excessive adductor bulge because of insufficient room in the medial
posterior area of socket Correct Ans - b. excessive pressure on the
hamstring muscles, resulting in stump edema
which one of the following gait faults is due to incorrect function of the
prosthesis
a. circumduction
b. pelvic rise
c. unequal arm swing
d. unequal step length Correct Ans - a. circumduction
