CCAT Gait Analysis and Locomotion 3

Question 1

In a normal walking dog, approximately what proportion of the gait cycle does each limb spend in the stance phase?

Accepted Answer

60% stance, 40% swing

Answer

25% stance, 75% swing

Answer

50% stance, 50% swing

Answer

75% stance, 25% swing

Question 2

What is the 'float phase' (suspension phase) in a trotting dog's gait cycle?

Accepted Answer

The brief moment when all four limbs are off the ground between diagonal pairs

Answer

The period when the hindlimbs are fully extended behind the body

Answer

The initial contact phase of the leading forelimb

Answer

The period of maximum vertical ground reaction force

Question 3

In dogs with hip dysplasia, which compensatory gait change is most commonly observed on force plate analysis?

Accepted Answer

Increased weight transfer to the forelimbs

Answer

Increased hindlimb push-off force

Answer

Decreased forelimb loading

Answer

Increased hip extension during terminal stance

Question 4

Which kinematic variable best quantifies the arc of individual joint movement during the swing phase of gait?

Accepted Answer

Joint angle excursion (range of motion)

Answer

Step width

Answer

Swing duration

Answer

Limb protraction angle

Question 5

What is the primary purpose of performing standardized gait analysis both before and after a rehabilitation intervention?

Accepted Answer

To objectively quantify treatment outcomes

Answer

To diagnose the underlying orthopedic condition

Answer

To determine appropriate drug dosage

Answer

To select the appropriate surgical technique

Question 6

Which of the following would best indicate improvement in gait symmetry following rehabilitation for a hindlimb lameness?

Accepted Answer

Increased stance duration on the previously affected limb

Answer

Decreased cadence on the treadmill

Answer

Increased peak vertical force on the contralateral (unaffected) limb

Answer

Decreased overall stride length

Question 7

What does the 'duty factor' represent in canine gait analysis?

Accepted Answer

The proportion of the stride cycle that a limb spends in stance phase

Answer

The ratio of peak vertical force to body weight

Answer

The angle of limb protraction at initial contact

Answer

The speed at which a dog transitions between gaits
