There are many kinds of mild, safety-oriented medical restraints which are widely used. For example, the use of bed rails is routine in many hospitals and other care facilities, as the restraint prevents patients from rolling out of bed accidentally. Newborns frequently wear mittens to prevent accidental scratching. Some wheelchair users use a belt or a tray to keep them from falling out of their wheelchairs. In fact, not using these kinds of restraints when needed can lead to legal liability for preventable injuries.
