Quiz – Phantom Limb Development in Congenitally Upper Limb-Deficient Individuals, Dr. Kristin Farry, PhD

1. True or False _________The author’s primary goal was to establish a large dataset in order to evaluate multi-function myoelectric control concepts.

2. True or False _________Most of the literature on phantom sensation focuses on pain; however, nearly all traumatic amputees have some sense of the amputated limb even without pain.

3. True or False _________A bipolar electrode configuration suited for amplitude-based myoelectric control was used instead of the more common monopolar configuration.

4. [Select the correct response.] The term _________is used to describe the exercise where the user moves the intact hand and wrist while simultaneously attempting to do exactly the same action with the amputated limb.

A. contra-lateral stimulation

B. contra-postal simulation

C. controversial stagnation

D. contradictory stimulation

5. [Select the correct response.] Total testing time for each subject was about _________hour(s), not counting breaks.

A. 1

B. 2

C. 3

D. 4

E. 5

6. True or False _________Subjects were asked to develop a prosthesis command set (consisting of motion-specific contractions) that they could remember and associate with the proposed prosthesis movements when they saw the motion prompts, and all chose to imagine moving a hand on their limb-deficient side through the desired prosthesis motions.

7. [Select the correct response.] A prosthesis controller adapted to each subject was developed and simulated. The controller is based on an evolutionary computing technique known as _________.

A. controlled programming

B. prosthetic design

C. genetic design

D. genetic programming

8. True or False _________According to the article, there was a strong connection between the imagined hand and the missing hand.

9. [Select the correct response.] Which of the following is NOT a potentially significant quantitative indicator of a “phantom” developing?

A. increases in signal-to-noise ratio (SNR)

B. decreases in the delay between the motion prompt and myoelectric response in the residual limb

C. decreases in the motion error (where the subject made a motion different from the one requested) rate

D. increases in motion identification accuracy of a simulated prosthesis controller after the “phantom” appeared

E. decreases in signal-to-noise ratio (SNR)

10. [Select the correct response.] Three subjects could name a specific time that they first felt the phantom - _________.

A. shortly after beginning the session

B. during the first break

C. just after the lunch break

D. during the afternoon break

E. just as the session was concluding

11. True or False _________The delay between the motion prompt and myoelectric response in the residual limb increased after the phantom sensation began.

12. True or False _________Many individuals with unilateral congenital limb-deficiency are actually traumatic amputees whose amputation occurred in utero.
