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

Diagonal phase

Answer

Lateral phase

Answer

Transition phase

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

Excessive lateral sway of the hindquarters during locomotion

Answer

A shortened hindlimb stride with toe dragging

Answer

Consistent interference between fore and hind hooves

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

Braking impulse

Answer

Mediolateral force vector

Answer

Propulsive impulse

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

Scissor gait with limb crossing

Answer

High-stepping hypermetric hindlimb action

Answer

Toe-dragging ataxic gait with proprioceptive deficits

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

It indicates hyperactivity of that limb's extensor muscles

Answer

It represents a normal gait variant in senior animals

Answer

It indicates increased proprioceptive drive to that limb

Question 6

Which spinal region dysfunction is most commonly associated with hindlimb propulsion deficits and a shortened caudal phase of the stride in horses?

Accepted Answer

Lumbosacral junction (L5–S1 or L6–S1)

Answer

Cervical region (C1–C5)

Answer

Mid-thoracic region (T6–T12)

Answer

Cranial thoracic junction (T1–T5)

Question 7

Which assessment method uses high-speed cameras and reflective markers on bony landmarks to quantify three-dimensional joint angles during locomotion?

Accepted Answer

3D kinematic motion capture

Answer

Force plate analysis

Answer

Inertial measurement unit (IMU) sensor system

Answer

Thermographic gait evaluation
