Lameness Locator uses the following movement parameter in measuring hind limb lameness
-
Pelvic rotation
-
Vertical movement of the pelvis (pelvic height)
Correct Answer
A. 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
Correct Answer
A. 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
Correct Answer
A. True -
- 5.
Minimum pelvic heights occur during the stance phases of the limbs
-
True
-
False
Correct Answer
A. True -
- 6.
Diff Max pelvis measures the push off component of hind limb movement
-
True
-
False
Correct Answer
A. True -
- 7.
What is a difference between how forelimb lameness is evaluated compared to hind limb lameness?
-
Diff Max and Diff Min are treated as dependent quantities in the forelimb evaluation and independent quantities in the hind limb evaluation
-
Diff Max and Diff Min are treated as dependent quantities in the hind limb evaluation and independent quantities in the forelimb evaluation
Correct Answer
A. Diff Max and Diff Min are treated as dependent quantities in the forelimb evaluation and independent quantities in the hind limb evaluation -
- 8.
Diff Min pelvis measures the push off component of hind limb movement
-
True
-
False
Correct Answer
A. False -
- 9.

Correct Answer
A. +/- 3mm -
- 10.
Maximum pelvic heights occur during the stance phases of the limbs
-
True
-
False
Correct Answer
A. 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
Correct Answer
A. The pelvis is rising less after push off 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
Correct Answer
A. The pelvis is falling less during stance of that limb -
