Answer: To ensure that the patient comes first and uphold the highest
standards of professionalism.
◍ Transradial amputees generate excursion through the motions of.
Answer: humeral flexion and extension, elbow flexion and extension, and
bi-scapular abduction
◍ The muscles that comprise the rotator cuff are.
Answer: Teres minor, supraspinatus, infraspinatus, subscapularis

variable cadence and requires a prosthesis for activities beyond walking?.
Answer: K3
◍ I'm being thrown forward.
Answer: Patient shoe heel to firm or too high

this.
Answer: Toe lever too short
◍ Above knee amputation/ transfemoral.
Answer: Between hip joint and knee joint
◍ Biceps muscle.
Answer: Is both a primary elbow flexor and supinator
◍ A TF pt comes in, upon doffing the suction socket you notice a red, wart
like formation, cracked skin distally. What is the name of this condition and
its cause.
Answer: Verrucous hyperplasia
◍ The primary function of the anterior suspension strap in a standard figure of
eight trans-radial harness is.
, Answer: to act as the main suspensor
◍ Transverse bench alignment for a TF prosthesis.
Answer: Knee externally rotated by 3-5°Foot externally rotated by 5-7°

elbow flexion- Frequently uses figure of 9 harnessing with body powered
prostheses

8 trans-radial harness is.
Answer: Act as the main suspensor
◍ Knee disarticulation amputee cosmetic concerns are.
Answer: Knee extends too far out when sitting or kneeling
◍ For a BK @ initial contact, if the pt feels their knee too flexed, what might
be causing this.
Answer: Faulty suspensionFlexion contracture

mediolateral dimension.
Answer: Ischial containment
◍ When bench aligning a BK, the medial/lateral placement is.
, Answer: inset 1/2"
◍ What is the purpose of the PTB bar in a patellar tendon bearing socket?.
Answer: weight bearing
◍ Sewn cross point harnesses rathe than a ring type cross point is done to:.
Answer: Increase excursion response
◍ What is the consequence of failing to report unethical practices as an ABC
practitioner?.
Answer: Potential disciplinary action under the Code of Professional
Responsibility.
◍ In which activity level does the patient have potential for ambulation beyond
basic walking (high impact, athletes, children)?.
Answer: K4
◍ Upon heel strike for a BK, where are the anterior/posterior forces?.
Answer: Anterior/distal and Posterior proximal
◍ For a AK @ initial and midswing, if the pt shows vaulting, what might be
causing this.
Answer: Excessive mechanical resistance to knee flexionProsthesis too
stableProsthesis too longPt habit
◍ In this type of alignment, the components are adjusted while the amputee is
wearing the prosthesis under static weight bearing (standing).
Answer: Static alignment
◍ For a AK @ pre-swing, if pt shows delayed knee flexion, what might be
causing this.
Answer: Prosthetic knee alignment too stableProsthetic knee mechanical
functions too stable
◍ Standard suspension design for transradial prosthesis.
Answer: Figure of eight harness with flexible or riged hinges
◍ Which component does not offer a heavy duty version?.
Answer: All (Outside hinges, flexible hinges, positive locking elbow, single
