Doc says the exercise tightens up loose ligaments & tendons... which are, 9 out of 10 times, the true culprit of most ankle sprains & breaks.

Thanks QJ  Shaolin Master Jimbo, I feel somewhat vindicated in my "muscle weakness" comments at the start of this thread.
I think Mr Bubble and myself are just describing the "other" side of the coin, in regard to ankle problems, not associated with bone damage that changes the re-hab equation.

I don't believe you can strengthen one, without strengthening the other.
I believe your Duck Walk is a specific type exercise while the balance board is more in the line of overall ankle/foot health.
I know people who had surgery with very poor results because they were told you couldn't re-hab their specific problem?

 Might or might not of been true, but I would give the re-hab (balance board/Duck walks a chance before I let someone cut on me. Surgery and drugs have their place, but so does more body friendly techniques.
Considering the cost of surgery/ Hospital re-hab and drug costs/side effects, that $20 dollar balance board/Shaolin Duck Walks seems  a real bargain ;)
