To 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
c
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
a
Rotation of the foot at heel strike may be cause by
a. stiff dorsiflexion bumper
b. a stiff plantar flexion bumper
c. external rotation of ankle axis
d. external rotation of knee axis
b
,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 much weight being borne on the ramus of the ischium
c. wedging of stump in the gluteus channel
d. walking with leg internally rotated
a
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
c
when adductor longus tightness is observed during initial fitting the AK socket
you should:
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
c
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
c
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
b
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
a
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
a
Medial whip is cause 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
d
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
a
When pulling the amputee into an AK socket the most important anatomical
landmark is the:
, a. gluteus maximus muscle
b. hamstring muscle group
c. adductor longus tendon
d. rectus femoris muscle
c
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
b
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
a
How does an excessively stiff planar flexion bumper in the prosthetic foot affect
knee stability?
a. increase knee stability excessively
b. has no affect on knee stability
c. decreases knee stability
d. makes it necessary to move the socket forward in relation to the knee bolt
c
at push off it is common for an AK amputee with well developed hamstrings
muscles to force himself off the ischial seat as his stump extends. how can this
trouble be avoided?
a. align the socket so the extensor muscles are elongated slightly
b. align the socket in a position of initial flexion
