What is a plumb line from point of rump?

• A. A Measurement Of Shoulder Angle
• B. A Line To Assess Neck Length
• C. The Line That Indicates Alignment Of Forelimbs
• D. Back Of Hock, Fetlock And Heel

Answer: (D)

A plumb line from the point of the rump provides a vertical reference to assess hindquarter alignment. The line should run straight down the hind limb along its posterior surface—over the back of the hock, then the fetlock, and to the heel. This position shows whether the hind limb is aligned to bear weight under the body and track straight, which is crucial for balanced movement and effective hippotherapy. If the line drifts, it indicates hind limb misalignment or conformational issues that can alter gait.

The other options point to measurements not related to this vertical Hind limb reference: shoulder angle is about the forelimb and shoulder region, neck length is an anterior-body measurement, and forelimb alignment concerns the front limbs.
