I was under the impression that Edea was manipulating the bangle itself. So Rinoa was forced to hold onto it as she was flung around the room. I don't know if she wore it or not, but I would hazard a guess and say she wore Odine's Bangle. Why? Because the common trope is that if someone is coming at you with something or trying to catch you in a trap, you turn it around and make them suffer the consequences (esp. if you are a villain) so it would make sense. Whether this has any effect on Rinoa or not, I have no idea.
