A twitch is a device used to help control a horse. The most common twitch has a long wooden handle with a loop of chain or rope at one end. The twitch is applied over the upper lip and twisted until tight. This is supposed to cause endorphins to be released and make the horse relax, however most people do not know how to accurately use a twitch and wind up causing pain to the horse. Some people will also apply the twitch to the horses ears, but this is wrong and should never ever be done.
