Means of restraint is a term used to describe any device or method used to limit the movement of an individual or animal. Two common examples of means of restraint are YOKE and REIN. A YOKE is a wooden beam that is placed across the shoulders of two animals, such as oxen, to enable them to pull a plow or cart in unison. Reins are straps attached to the bridle of a horse, which are used by the rider to control the horse's movements.
