Reflexions on wrist flexes and rotations

[Adam Frost]

There is no symbol that is specific to the thumb or pinky. Let's pull back a little. When you rotate you hand, notice that the when the thumb goes one way, the pinky goes the other way. So either arrow could work. That is the reason I used doors as an example. There is a clear "leading" side. So you have to ask yourself which is the "leader" and then pick the according arrow. (Just a side note, I have noticed with me that more often than not it is the thumb that does the leading. However, notice that with the sign for the door opening out that it was the pinky leading. So it isn't absolute, but a majority)

Hi Adam,
     Your explanation is very clear.  Thank you for explaining this to me.
     Just one more question.  Which arrow is for the thumb and which is for the pinky?  What if the hand is pointing down instead of up like in your examples?  Or should I be more preoccupied if it is an inward or outward rotation rather than thumb or pinky rotation?

 This is a hard one to understand because there isn't a clean distinction. It goes by the feel of what is leading the movement, the pinky or the thumb. Maybe this will help a little. When you are doing a rotation, imagine that you have to keep either the pinky or the thumb still. It will always be one or the other. Ok, and example. In ASL the flat hand is used to show the door. Now a door can open inward or outward. I have written those two. Notice which is leading, the thumb or the pinky. Notice that it can not be the other way around because one side of the door is on a hinge. ;-) I hope this helps. If you need more clarification, just ask. :-)
