Linear Kinematics Applications

Question 1

Abduction

Answer 1

the movement of a limb moving away from the midline of the body

Question 2

Adduction

Answer 2

the movement of a limb moving towards the midline of the body

Question 3

Anterioposterior Axis

Answer 3

(AKA Sagittal Plane) splits the body into posterior and anterior sections

Question 4

Calibration

Answer 4

comparison and adjustment of measurement values to be within a certain range of accuracy

Question 5

Extension

Answer 5

a straightening movement that increases the angle between body parts

Question 6

Longitudinal axis

Answer 6

Superior and Inferior relationship

Question 7

Mediolateral axis

Answer 7

AKA frontal or coronal axis

Question 8

Roll vs. Pitch. vs Yaw

Answer 8

regarding an aircraft in flight
Roll: rotation of the aircraft about an axis running nose to tail
Pitch: nose rotating up or down about an axis running wing to wing
Yaw: rotation left or right about an axis running up and down

Question 9

What are the strengths and weaknesses of quantitative biomechanical analysis?

Answer 9

• results are limited as they provide numerical descriptions rather than detailed narrative and generally provide less elaborate accounts of human perception
• they allow for a broader study, involving a greater number of subjects and allow numerical accuracy

Question 10

Anatomical Reference Position

Answer 10

standing erect, facing forward, feet together and arms at the side with the palms facing forward

Question 11

Why would you choose to analyze movement using a fixed reference as opposed to a moving reference

Answer 11

By using a fixed reference point, it is easier to compare changes in the system. Concerning anatomical position, it is a universal fixed reference point for everyone to free back to when comparing changes

Question 12

What types of movements occur in the sagittal plane?

Answer 12

Flexion, extension, hyper extension
