4 things to consider

Answer 2

1. FOR
2. FBD
3. Vectors
4. QAA

Question 3

egocentric FOR

Answer 3

(local) up/down
forward/backward (front/back)
left/right

Question 4

planes of reference

Answer 4

Sagittal (splits left/right side), frontal (splits front/back), transverse (splits top/bottom)

Question 5

keys to observation

Answer 5

1. principal plane of movement
2. see the entire movement
3. closer for fine movements, farther for gross movements
4. view from several planes
5. multiple cameras

Question 6

axis

Answer 6

x: intersects sagittal and transverse planes (front to back)
y: intersects frontal and transverse planes (left to right)
z: intersects frontal and sagittal planes (top to bottom)

Question 7

global vs. egocentric axis

Answer 7

global: based on landmark in surrounding environment (corner of room)
egocentric: landmarks on body

Question 8

parallel axis

Answer 8

lines throughout the body which show asymmetry, improper body alignment
