CCAT Gait Analysis and Locomotion 2

Question 1

What does a reduced peak vertical force (PVF) on a force plate analysis indicate about the tested limb?

Accepted Answer

Reduced weight bearing consistent with lameness

Answer

Increased muscle mass in that limb

Answer

Normal gait symmetry

Answer

Improved proprioception in that limb

Question 2

What is the primary advantage of an underwater treadmill over a land treadmill for gait rehabilitation and analysis?

Accepted Answer

Reduced joint loading due to buoyancy

Answer

Higher achievable speeds

Answer

More accurate ground reaction force measurement

Answer

Better assessment of proprioceptive deficits

Question 3

What is 'crabbing' in canine gait?

Accepted Answer

Lateral displacement of the hindquarters relative to the forequarters

Answer

Unilateral forelimb lameness causing a head-bob

Answer

Excessive hip extension during the push-off phase

Answer

Abnormal stifle flexion during the swing phase

Question 4

Which gait assessment technology uses a pressure-sensitive walkway surface to capture paw contact patterns and force distribution?

Accepted Answer

Pressure walkway (e.g., Tekscan)

Answer

Kinematic motion capture system

Answer

Electromyography (EMG)

Answer

Diagnostic ultrasonography

Question 5

What does 'cadence' refer to in canine gait analysis?

Accepted Answer

Number of steps taken per unit of time

Answer

Speed of locomotion in meters per second

Answer

Length of each stride in centimeters

Answer

Width between the left and right stance limbs

Question 6

In neurological patients, what gait abnormality is characterized by exaggerated limb flexion and overshooting during the swing phase, often associated with cerebellar dysfunction?

Accepted Answer

Hypermetria

Answer

Spasticity

Answer

Proprioceptive ataxia

Answer

Hypometria

Question 7

Which gait asymmetry finding on video analysis would most strongly suggest a weight-bearing hindlimb lameness?

Accepted Answer

Hip hiking (elevation of the pelvis) on the lame side during swing

Answer

Head nodding upward when the lame hindlimb contacts the ground

Answer

Head nodding downward when the lame hindlimb contacts the ground

Answer

Increased stride length on the contralateral forelimb
