CAC Gait Analysis and Locomotion Assessment 2

Question 1

In equine locomotion, what is the term for the brief period during the canter or gallop when no hooves are in contact with the ground?

Accepted Answer

Suspension phase

Answer

The suspension phase (also called the aerial phase) is the period during canter or gallop when all four limbs are simultaneously off the ground.

Question 2

What does 'overtracking' refer to in equine gait evaluation?

Accepted Answer

The hind hoof landing in front of the print left by the ipsilateral forehoof

Answer

Overtracking occurs when the hind hoof lands cranial to the print made by the ipsilateral forehoof, indicating good hindquarter engagement and adequate range of motion.

Question 3

In force plate gait analysis, which parameter directly measures the maximum downward load a limb applies to the ground during stance?

Accepted Answer

Peak vertical force (PVF)

Answer

Peak vertical force (PVF) measures the maximum downward force a limb exerts on the ground during the stance phase and is the primary indicator of weight-bearing symmetry.

Question 4

Which hindlimb gait pattern in large-breed dogs is classically associated with bilateral hip dysplasia?

Accepted Answer

Bunny-hopping or pelvic sway gait

Answer

Dogs with bilateral hip dysplasia often exhibit a bunny-hopping gait at the trot or canter, where both hindlimbs advance together, or a characteristic pelvic sway to reduce loading on painful hip joints.

Question 5

What is the significance of a reduced stance phase duration in one limb during kinematic gait analysis?

Accepted Answer

It suggests pain or instability causing the animal to minimize weight-bearing time on that limb

Answer

Reduced stance phase duration in one limb indicates the animal is minimizing time loading that limb, which is a compensatory response to pain or structural instability.
