<unk> s are a subset of general physical<unk>  used for medical purposes. Unlike some other forms of<unk> ,<unk> s are designed to<unk> their wearer without causing pain.<unk> s are generally used to prevent people with severe physical or mental disorders from harming themselves or others.
Forms of<unk>  include four-point<unk> s, fabric body holders and straitjackets, as well as less-confining devices such as safety vests, jackets, lap and wheel chair belts.
Although<unk> s, used properly, can help prevent injury, they can also be dangerous. The U.S. Food and Drug Administration (FDA) estimated in 1992 that at least 100 deaths occur annually in the U.S. from their improper use in nursing homes, hospitals and private homes.  Most of the deaths are due to strangulation.  The agency has also received reports of broken bones, burns and other injuries related to improper use of<unk> s.
Because of the potential for abuse, the use of<unk> s is regulated in many jurisdictions.
