COC Assessment & Evaluation 1 — Questions and Answers
Question 1: The Medicare Functional Classification Level (MFCL or K-level) K2 describes a patient who:
- Has the ability to traverse low-level environmental barriers at a fixed cadence (Correct answer)
- Has the ability to vary cadence and traverse most barriers
- Uses a prosthesis for transfers and limited household ambulation only
- Has high-impact activity potential
Correct answer: Has the ability to traverse low-level environmental barriers at a fixed cadence
K2 describes a limited community ambulator who can traverse low-level barriers such as curbs, stairs, and uneven surfaces at a fixed pace.
Question 2: Which clinical outcome measure assesses a prosthetic user's satisfaction with their device using a self-reported questionnaire?
- TAPES (Trinity Amputation and Prosthesis Experience Scales) (Correct answer)
- 6-Minute Walk Test
- Timed Up and Go (TUG)
- Berg Balance Scale
Correct answer: TAPES (Trinity Amputation and Prosthesis Experience Scales)
TAPES is a validated self-report instrument measuring psychosocial adjustment, activity restriction, and prosthesis satisfaction in amputees.
Question 3: During a lower limb prosthetic gait assessment, vaulting by the sound limb most commonly compensates for:
- Excessive prosthetic limb length or insufficient knee flexion in swing (Correct answer)
- Weak hip extensors on the prosthetic side
- Excessive socket flexion angle
- Anteriorly placed prosthetic foot
Correct answer: Excessive prosthetic limb length or insufficient knee flexion in swing
Vaulting (rising on the sound-side toe) provides extra ground clearance for a prosthetic limb that is too long or fails to flex adequately during swing.
Question 4: In orthotic evaluation, the Thomas test is used to assess:
- Hip flexion contracture (Correct answer)
- Hamstring flexibility
- Tibial torsion
- Subtalar neutral position
Correct answer: Hip flexion contracture
The Thomas test (bringing one knee to chest while the other leg lies flat) reveals hip flexion contracture when the flat leg rises from the table.
Question 5: The Amputee Mobility Predictor (AMP) is administered:
- Without a prosthesis to establish baseline functional capacity (Correct answer)
- Only with the patient wearing their definitive prosthesis
- Only in an aquatic environment
- Exclusively via patient self-report questionnaire
Correct answer: Without a prosthesis to establish baseline functional capacity
The AMP-noPro version is administered without a prosthesis to predict rehabilitation potential and appropriate prosthetic prescription prior to fitting.
Question 6: Which residual limb shape is considered most ideal for prosthetic fitting?
- Cylindrical with a well-healed, non-adherent scar (Correct answer)
- Conical with a bulbous distal end
- Bony prominences well-padded with redundant tissue
- Inverted cone with excessive soft tissue distally
Correct answer: Cylindrical with a well-healed, non-adherent scar
A cylindrical residual limb with a non-adherent, well-healed scar distributes pressure evenly and provides the most stable prosthetic fit.
