My little arab learned at some point in time in her life that if she reared when being asked to something she didn't want to or was scared of that she didn't have to do it. It has taken a while to correct this idea in her head in fact last weekend on a trail ride she gave me a refusal to cross a creek, second time I asked she reared, I made her do a bunch or circles and the third time she went across of course after that behavior I made her cross back and forth 5 times before we moved on.
If you can feel the rear coming on you can stop it bend your horses neck in one direction horses use their neck for balance so with the horses head turned it should make it rather difficult to attempt a rear. Have the horse turn circles till they relax then go back the start of where they were acting up and try again. I would repeat this several times. If the horse keeps acting up keep on going. This is of course after eliminating any chance of this because of a physical problem or ill fitting tack.
There is a chance that the first time it happened something scared her. You might be tensing up thinking she might rear again and could in fact be causing it. If you are nervous she will think there is something to be nervous about and be rearing as a result of that.
