Vt Ll Touch Core Concepts: Biomechanics Of Hind Limb Lameness

1. A perfectly symmetric, robotic horse would have Diff Max and Diff Min pelvis values of (or very close to) zero.

True

False

2. Lameness Locator uses the following movement parameter in measuring hind limb lameness

Pelvic rotation

Vertical movement of the pelvis (pelvic height)

3. Vertical movement of the pelvis is a better indicator of lameness than pelvic rotation because:

Vertical pelvic movement is more closely associated biomechanically with forces on the hind limbs

Rotation of the pelvis is more affected by things other than lameness, including anatomy and comformation

All of the above

4. In the hind limb ray plot, time moves left to right along the X axis for the LH and the RH subplots.

True

False

5. Minimum pelvic heights occur during the stance phases of the limbs

True

False

6. Diff Max pelvis measures the push off component of hind limb movement

True

False

7. What is a difference between how forelimb lameness is evaluated compared to hind limb lameness?

8. Diff Min pelvis measures the push off component of hind limb movement

True

False

9. The reference ranges (thresholds) for Diff Max and Diff Min pelvis are:

Zero

+/- 3mm

+/- 6mm

8.5 mm

10. Maximum pelvic heights occur during the stance phases of the limbs

True

False

11. On the Lameness Locator ray plot, red rays drawn up on either the LH or the RH indicate:

The pelvis is rising more after push off of that limb

The pelvis is rising less after push off of that limb

The pelvis is falling less during stance of that limb

The pelvis is falling more during stance of that limb

12. On the Lameness Locator ray plot, green rays drawn downward on either the LH or the RH indicate:

The pelvis is rising more after push off of that limb

The pelvis is falling more during stance of that limb

The pelvis is rising less after push off of that limb

The pelvis is falling less during stance of that limb
