COC Assessment & Evaluation 2 — Questions and Answers
Question 1: The Timed Up and Go (TUG) test measures which aspect of functional mobility?
- Time to rise from a chair, walk 3 meters, turn, return, and sit (Correct answer)
- Time to climb 12 stairs and descend
- Distance walked in 2 minutes on a flat surface
- Balance while standing on one leg for maximum time
Correct answer: Time to rise from a chair, walk 3 meters, turn, return, and sit
The TUG times a patient from seated, walking 3 meters, turning around, returning, and sitting — reflecting dynamic balance and basic mobility.
Question 2: When evaluating spinal orthosis candidates, the Cobb angle is measured on radiographs to quantify:
- Scoliotic curve magnitude (Correct answer)
- Sagittal kyphosis severity only
- Vertebral rotation degree
- Disc height narrowing
Correct answer: Scoliotic curve magnitude
The Cobb angle, measured between end vertebrae of a scoliotic curve on AP radiograph, is the standard metric for scoliosis severity and treatment decisions.
Question 3: Which standardized test is specifically designed to assess balance confidence in persons with lower extremity amputation?
- Activities-specific Balance Confidence (ABC) Scale (Correct answer)
- Functional Reach Test
- Single Leg Stance Test
- Dynamic Gait Index (DGI)
Correct answer: Activities-specific Balance Confidence (ABC) Scale
The ABC Scale is a 16-item self-report measure of balance confidence during activities of daily living, validated in the amputee population.
Question 4: During clinical evaluation of an AFO candidate with foot drop, the practitioner should assess which of the following first?
- Muscle strength, tone, and ankle ROM (Correct answer)
- Shoe size and lifestyle goals only
- Insurance coverage and device cost
- Cosmetic preference for the orthosis material
Correct answer: Muscle strength, tone, and ankle ROM
Muscle strength, spasticity or tone, and passive ankle ROM determine the appropriate AFO design (flexible vs. rigid, articulated vs. solid) for foot drop management.
Question 5: The Rivermead Mobility Index (RMI) is most commonly used to assess patients in which clinical population?
- Stroke and neurological rehabilitation (Correct answer)
- Pediatric scoliosis
- Upper extremity amputees
- Diabetic foot ulcer management
Correct answer: Stroke and neurological rehabilitation
The RMI is a validated 15-item mobility assessment designed for and widely used in stroke and neurological rehabilitation settings.
Question 6: In a prosthetic evaluation, pistoning refers to:
- Vertical movement of the residual limb within the socket during gait (Correct answer)
- Rotation of the prosthetic foot during swing
- Mediolateral shift of the socket on the residual limb
- Excessive knee flexion at initial contact
Correct answer: Vertical movement of the residual limb within the socket during gait
Pistoning is the up-and-down motion of the residual limb sliding within the socket, indicating inadequate suspension and causing skin shear forces.
