power balance bands

I think that power bands have very little affect. I also think its in peoples head that it works. You don't need a bracelet to be great at a sport. I would test this by having a person blind folded and put a regular jelly bracelet on them first and do the balance test and then put the power band on and do the same test and ask the person if the first or second bracelet had any effect. I think that its important to look at all sides of the story because one thing could have a greater affect then the other.
