Question 1 of 6

1. Question
Which of the below would not be considered quantitative Kinematic Analysis?
- Animals have markers placed on specific anatomic locations which are used by Computer-Assisted Video analysis to calculate step distances in meters
- When viewing a video in biomechanical software, the ear is selected and its vertical movement is measured in centimeters to determine the vertical distance of the animals “head bob”
- Three points are selected (the point of the shoulder, the hip and the paw) which create a hip angle. When viewed in a video, the hip angle is measured (in degrees) at certain points to determine angular movement of the hip during a stride
- A Veterinarian observes a dog running in a field to analyze it’s movement. The veterinary determines the dog is running “good”.
Correct

Question 2 of 6

2. Question
Which of the below best describe the phases of a step cycle?
- The step cycle is made up of a stance phase and a swing phase
- The wash and rinse cycle
- The step cycle only is when the paw is contact the surface
- The step cycle is used to determine the actions of the dog as they go up steps
Correct

Incorrect
Question 3 of 6

3. Question
Which of the below would not be a descriptor associated with the stride cycle of the quadruped?
- During quadrupedal locomotion, the stride begins at a defined point and ends when that point next reoccurs, i.e. when the left rear paw touches down until the left paw next touches down
- The actions of the body that occur beginning when one paw touches down until that paw again touches
- The stride cycle is only relative to a racing gallop and no other stride actions
- In a racing gait, the stride cycle can include a stance phase and a flight phase
Correct

Incorrect
Question 4 of 6

4. Question
Which of the below would not be a descriptor associated locomotion?
- The dog’s coat color plays and integral role in the dog’s gait patterns
- A dog’s gait can be defined as a description of movements related to a sequence of strides
- Step cycles can be measured linearly to assess step cycle distances during locomotion
- During locomotion, joint angles can be measured to assess limb movement
Correct

Incorrect
Question 5 of 6

5. Question
Kinematic data derived from racing greyhounds provided some important information on the biomechanics of how all dogs run. Which of the below would be a false statement?
- Velocity had a significant decrease when comparing greyhound velocity at the beginning to the velocity at the end
- The stride distance had a significant decrease from the beginning measurements to the measurements and the end
- The stride frequency had a significant decrease from the beginning measurements to the measurements and the end.
- When comparing the beginning measurements to those at the end, the front flight distance increased and rear flight distance decreased
Correct

Incorrect
Question 6 of 6

6. Question
The data collected on the racing greyhounds showed what seems to be segmental fatigue of selected muscles. Although there is most likely fatigue of the entire musculature, which anatomical region was most associated with the reduced velocity at the end of a race?
- The cervical muscles
- The thoracic muscles
- The coccygeal muscles
- The longissimus muscles
