Hope I don't teach it to you the wrong way. I have never been 100% sure of myself with this one, but this is how I roll.
6 - obeys command
5 - appropriate reacts to pain / purposeful movement
4 - inappropriately reacts to pain
3 - decorticated posture (mummy arms)
2 - decerebrated posture (arms at side)
1 - no response to pain
Example of 5 is if they don't follow commands, you do the trapezius pinch, and they move their arm towards where you are squeezing at to smack off your hand. Another example is if they don't follow commands, you palpate their abdomen, and they start to guard their abdomen.
Flexion (decorticate posture) and extension (decerebrate posture) looks like this.
I believe I read from paramedicine.com a tip like
6 - OBEYS
5 - TOWARDS (pain)
4 - AWAY (pain)
3 - IN
2 - OUT
1 - NONE
The arms are going IN (towards) the midline in #3, and they are goint OUT (to the side) away from midline in #2. It's a posture. #5 is going TOWARDS the source of pain. #4 is going AWAY from the source pain.
Edit Found the page I was talking with paramedice.com. They stole the same image I used! Coincidences.

There was actually TOWARDS and AWAY in regard to just the arms or whole body. Meh, I was close enough.
