  • 2. 

    In the blocking AIDE, the second AIDE statement indicates the percent improvement of the lameness variable towards the reference range.

    • True

    • False

    Correct Answer
    A. True
  • 3. 

    Results of blocks should only be compared to trials on the same surface. 

    • True

    • False

    Correct Answer
    A. True
  • 4. 

    If evaluating blocks on the lunge is desired, the easiest method is to use the General Comparison report to compare a lunge left pre and post block (or lunge right pre and post) side by side. Blocking AIDEs are not provided on lunging trials. 

    • True

    • False

    Correct Answer
    A. True
  • 5. 

    What  should be considered in evaluating blocks?

    • Is the amount of change outside of the 95% confidence intervals for repeatability?

    • The overall percentage of improvement

    • Did a change in timing occur?

    • All of the above

    Correct Answer
    A. All of the above
  • 6. 

    In the blocking AIDE, the first statement indicates the percent improvement of the lameness variable toward zero asymmetry (absolute improvement in the measure)

    • True

    • False

    Correct Answer
    A. True
  • 7. 

    A stable lameness should be confirmed before blocking a horse. A stable lameness is indicated by two back to back trials with results similar in: 

    • A) lame limb

    • B) amplitude of lameness

    • C) timing of lameness

    • All of the above

    Correct Answer
    A. All of the above
  • 8. 

    If a lameness is not stable the veterinarian should: 

    • A) exercise the horse such as lunging for a few minutes to see if it can be stabilized

    • B) repeat the straight line trials after exercise

    • C) block the horse

    • D) Both A and B

    Correct Answer
    A. D) Both A and B
  • 9. 

    The 95% confidence intervals for forelimb and hind limb lameness are (respectively)

    • +/- 6mm for Diff Max and Diff Min Head (or 8.5 for VS); +/- 3mm for Diff Max and Diff Min Pelvis

    • 6mm for VS and 3mm for Diff Max and Diff Min Pelvis

    • 3mm for VS and +/- 6mm for Diff Max Diff Min Pelvis

    Correct Answer
    A. +/- 6mm for Diff Max and Diff Min Head (or 8.5 for VS); +/- 3mm for Diff Max and Diff Min Pelvis
  • 10. 

    Improvement in Total Diff Head/VS, Diff Max Pelvis or Diff Min Pelvis less than 26% will be considered "no significant improvement" in the blocking AIDE. 

    • True

    • False

    Correct Answer
    A. True
  • 11. 

    When using the blocking comparison report, straight line blocking trials should be compared to the last straight line trial before the block being evaluated was applied in order get an accurate percent change from that specific block (i.e. low four point compared to abaxial, abaxial compared to PDN...).

    • True

    • False

    Correct Answer
    A. True
  • 12. 

    Forelimb lameness and hind limb lameness percent improvement is calculated from (respectively) the  Total Diff Head/Vector Sum and the Diff Max/Diff Min Pelvis values.

    • True

    • False

    Correct Answer
    A. True
  • 13. 

    Straight line blocking trials should be compared using the comparison report

    • True

    • False

    Correct Answer
    A. True
  • 14. 

    A change in timing of lameness with no improvement in amplitude of lameness  may be considered a positive block 

    • True

    • False

    Correct Answer
    A. True
  • 15. 

    When calculating change of a lameness measure, the absolute percent improvement calculation will always be smaller than the percent toward the reference range. 

    • True

    • False

    Correct Answer
    A. True
  • 16. 

    If the amount of change is within the 95% confidence intervals of repeatability the user should

    • Keep blocking

    • Stop blocking

    • Repeat the trial to confirm results

    Correct Answer
    A. Repeat the trial to confirm results
  • 17. 

    Percent improvement of Diff Max Pelvis (push off component) and Diff Min Pelvis (impact component) are calculated as one combined lameness measure.

    • True

    • False

    Correct Answer
    A. False
