what is posturing
Decerebrate posture is an abnormal body posture that involves the arms and legs being held straight out, the toes being pointed downward, and the head and neck being arched backward. The muscles are tightened and held rigidly. This type of posturing usually means there has been severe damage to the brain. A severe injury to the brain is the usual cause of decerebrate posture. Opisthotonos (a severe muscle spasm of the neck and back) may occur in severe cases of decerebrate posture. Decerebrate posture can occur on 1 side, on both sides, or in just the arms.
