Neural rerouting around injuries is fast

I injured my hand slightly a couple of days ago.  The injury is such that I want to avoid using a couple of the fingers in my right hand for a few days.  I was amazed that my brain quickly and subconsciously came up with new ways of picking up and moving objects, getting dressed,  carrying out other daily tasks, and even typing, a skill that ordinarily takes a very long time to learn and one for which I have subconsciously developed a nonstandard approach I cannot verbally describe.  Accidental stresses on the hand have been very rare. 

I want to harness this sort of rapid rerouting for other types of physical motion learning such as improving posture or riding a snowboard properly.

Mm, fine motor adjustments can be very different from/faster than gross... but if you pick anything up, let me know!

To make it fast, the consequences of messing up probably need to be bad, one way or another. Also immediate.

True, true. Also, the implementation would have to vary depending on how the body anticipates potential pain. If it plans around pain by looking at what muscles would be needed to do a motion in various ways, and then picks ways that don't conflict with known pained muscles, then this technique would have to cause pain to a specific muscle whenever it is moved in order to work.

You just gave me an idea: hook up a spaced repetition system to an electric shock dingus. Shock intensity could be based on learned difficulty of the item in question. I bet it would work well, and I'm not kidding!

As in... you'd get a bigger shock for missing an easier question?

If stress from shock avoidance gets too high, you could end up suppressing memory.

Clearly it can work wonders...

Actually I was thinking that you get a worse shock when you miss a harder card. That way you train yourself to avoid shocks by expending more effort in learning the hard ones.
