Physical restraint refers to the practice of rendering people helpless or keeping them in captivity by means such as handcuffs, shackles, straitjackets, ropes, straps or other forms of physical restraint. Alternatively, unarmed combat techniques or sheer force of numbers may be used to restrain a person.
Physical restraint may be used:
Restraining someone against their will is generally a crime in most jusrisdictions, unless it is explicitly sanctioned by law.
The misuse of physical restraint has resulted in many deaths.
Physical restraint can be dangerous, sometimes in unexpected ways. Examples include:
- postural asphyxia
- unintended strangulation
- death due to choking or vomiting and being unable to clear the airway
- death due to inability to escape in the event of fire or other disaster
- death due to thirst or starvation due to the inability to escape
- cutting off of blood circulation by restraints
- nerve damage by restraints
- cutting of blood vessels by struggling against restraints, resulting in death by loss of blood
- death by hypothermia or hyperthermia whilst unable to escape
For these and many other reasons, extreme caution is needed in the use of physical restraint.
Gagging a restrained person is highly risky, as it involves a substantial risk of asphyxia, both from the gag itself, and also from choking or vomiting and being unable to clear the airway. In practice, simple gags do not restrict communication much; however, this means that gags that are effective enough to prevent communication are generally also potentially effective at restricting breathing. Gags that prevent communication may also prevent the communication of distress that might otherwise prevent injury.
