Frame of Reference Video

Question 1

Frame of reference helps us to define where ___?

Answer 1

Something is in space and how to view movement.

Question 2

Frame of Reference

Answer 2

A way to describe an objects position in space and whole body orientation alone and with respect to external landmarks.

Question 3

T/F Frame of reference helps us to define where something is and how to view movement

Answer 3

True

Question 4

What two FOR do we use?

Answer 4

Global and local (egocentric)

Question 5

T/F Egocentric (local) frame of reference is referring to the person themselves and allows us to define what is up/down, forward/backward (front/back) and left/right.

Answer 5

True

Question 6

Plane

Answer 6

In mathematics, a plane is a fundamental two-dimensional object. Intuitively, it may be visualized as a flat sheet of paper of infinite size.

Question 7

Mid-sagittal plane

Answer 7

Cuts the body into left an right positioned in the middle

Question 8

Sagittal plane (Medial or midline plane)

Answer 8

Cuts the body into left and right

Question 9

Any plane parallel to the mid-sagittal plane is called the ____ plane?

Answer 9

Para-sagittal plane or just sagittal

Question 10

What movements are useful to see from the sagittal plane?

Answer 10

-Running, jumping, olympic lifting

Question 11

Frontal plane (Coronal) is ____ to the sagittal plane?

Answer 11

Perpendicular

Question 12

What movements are useful to from the frontal plane?

Answer 12

Tennis, volleyball, agility tests

Question 13

Transverse plane

Answer 13

Cuts our top from our bottom and is orthogonal (perpendicular) to both the frontal and sagittal planes

Question 14

What movements are useful to see from the transverse plane?

Answer 14

Rotational movements (i.e. volleyball, soccer, baseball, ballet)

Question 15

What is an axis?

Answer 15

• Straight line where two planes intersect
• Is a line in which an object may rotate.
• The distance an object is along a certain axis is an important reference position

Question 16

Where can be define our 0,0 coordinate at?

Answer 16

Where all 3 axis intersect

Question 17

The intersection of what planes make the Z axis?

Any distance along this axis is measured as an up and down

Answer 17

Frontal and sagittal

Question 18

The line of intersection of what planes create the Y axis?Any distance along this axis is measured as left and right

Answer 18

Frontal and transverse

Question 19

The line of intersection of what planes make the x-axis?

Distance along this axis is a measure of front and back

Answer 19

Sagittal and transverse

Question 20

T/F A global and egocentric axis system is based on a landmark such as the corner of a room, layout of a field or court or a piece of equipment can be used to visualize and instruct movement

Answer 20

True

Question 21

T/F FOR allows us to guide our observation by aiding us in choosing appropriate viewing angles in order to capture all critical movements within a plane of view.

Answer 21

True

Question 22

T/F Viewing from different planes will give different perspectives?

Answer 22

True

Question 23

Where to observe?

Answer 23

1. Determine the principal plane of movement
   - Or the plane that captures the most important feature of skill
2. Make sure the line of site (i.e. camera) is perpendicular to the line of movement (i.e. plane)
3. Set up other cameras to view the secondary planes of movement (i.e. for sprinting you would set up a camera in the frontal and sagittal plane)

Question 24

T/F Use parallel axes (parallel lines) to view motion in the frontal, sagittal and transverse planes. You can draw lines in different places on the body (i.e. shoulders, hips, knee, elbows, ankles). In standard anatomical position, these should be in parallel alignment. If not, it could represent improper body alignment.

Answer 24

True

Question 25

Is the strategy of using parallel lines used to determine postural abnormalities in the frontal plane because drawing the lines enhances the asymmetry?

Answer 25

Yes, it allows the observer to see posture abnormalities

Question 26

Where do you see improper body alignment in the body with parallel lines in the transverse plane?

Answer 26

Hip and shoulder problems

Question 27

What about in the sagittal plane?

Answer 27

You can observe pelvic or lumbar tilt (lordosis)

Question 28

T/F We can also view different styles and performancewith parallel lines

Answer 28

True

Question 29

T/F We can also view different styles and performance with parallel lines

Answer 29

True
