Twitch (device)

Twitch (device)

A twitch is a device that is used to restrain horses for various stressful situations, such as veterinary treatment. It is made up of a stick-like handle or metal ring with either a loop of chain or rope on the end, which is wrapped around the upper lip of the horse.

How the twitch works

The upper lip of the horse is grasped and the loop of chain or rope is placed around it, then the handle of the twitch is twisted until the loop is tightly around the lip. The twitch does not work by distracting the horse, as is sometimes thought, but instead causes the release of endorphins from the horse's brain, producing a calming effect. The twitch is considered a very humane method of restraint and is commonly used by horsemen and veterinarians alike.

Misuses of the twitch

The twitch is not intended for use on any other part of the body of the horse other than the upper lip. It may cause permanent damage and behavioral issues (such as a head-shy horse when used on the ear) if it is used incorrectly. Additionally, if a twitch is left on for an extended period of time, its effects will diminish. This is thought to be because the endorphin levels of the horse are eventually expended.
