<unk>  is the first step of<unk>  movement, an early aspect of emergency medical care. It is the procedure used to put the<unk>  (the patient) on a stretcher. Developed emergency services use<unk>  devices, such as scoop stretchers, that allow secured<unk>  with minimal personnel. Other methods (explained below) can be used when such devices are not available. Since only stabilised<unk> es are moved (except in unusual circumstances), the<unk>  is usually never performed in emergency; emergency movements are sometimes performed to respect the Golden Hour. This depends on the organisation of the medical services and on the specific circumstances. Maximum care must be taken to avoid to worsen an unstable trauma. The head-neck-chest axis must be kept straight to protect the spine, and the first responders must keep the patient's body stable (no movement of the feet) during the lift. The first responders have to carry a heavy load (probably more than 20 kg for an adult<unk>  in an uncomfortable position. There is thus a risk of injury to the carrier, especially of the lumbar back. To avoid an injury, they must push with their legs (quadriceps), trying to keep their back straight.
