Vt Ll Touch: Stabilizing The Lameness

1. The evaluator should not rely on the AIDE statements of severity of lameness to determine if a lameness is stable between two trials, but rather use the actual lameness variables.

True

False

2. A stable lameness is one that is consistent in two back to back trials in:

Amplitude

Timing

Limb involved

All of the above

3. When assessing stride by stride variability, the standard deviation should be less than the absolute value of the mean lameness measure (or not much greater).

True

False

4. What can you do to reduce stride to stride variability?

Reduce wiggling of sensors

Get more strides

Sedate minimally if misbehaving horse

Change surface or environment

All of the above

5. Lameness may be stabilized by:

Lunging

Walking

Trotting back and forth

All of the above

6. Trial to trial variability is assessed by the repeatability of successive trial results. Variability is in the horse, not the equipment.

True

False

7. Two successive trials with results that vary within the 95% confidence intervals provide 95% certainty that those results are the same.

True

False

8. An unstable lameness is one where results are not consistent between successive trials. Results differ by (more than/less than) the 95% confidence intervals.

More than

Less than

9. What are the 95% confidence intervals for Diff Max and Diff Min Head?

6 mm

3 mm

8.5 mm

10. What are the 95% confidence intervals for Diff Max and Diff Min Pelvis?

6 mm

3 mm

8.5 mm

11. Stride by stride variability is more common in hind limb measurement.

True

False

12. What is the 95% confidence interval for forelimb Vector Sum?

6 mm

3 mm

8.5 mm
