Ll Touch: Using The Q In Evaluating Diagnostic Blocks

1. When blocking a mild lameness or attempting to evaluate small changes, trials should always be repeated to confirm results.

True

False

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

True

False

3. 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

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

True

False

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

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

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

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

9. 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

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

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

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

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

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

13. Straight line blocking trials should be compared using the comparison report

True

False

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

True

False

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

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

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
