  1. Medical history questions may include:

    • 2. Is there a pattern to the postures?

  2. Decorticate Posture
    Abnormal posturing in which a person is stiff with bent arms, clenched fists, and legs held out straight. The arms are bent in toward the body and the wrists and fingers are bent and held on the chest. This type of posturing is a sign of severe damage in the brain. Less serious than decerebrate posture.
  3. Decerebrate Posture
    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 backwards. The muscles are tightened and held rigidly. This type of posturing usually means there has been severe damage to the brain.  More serious than decorticate posture.
  4. Opisthotonos Condition
    Condition in which the body is held in an abnormal position. The person is usually rigid and arches the back, with the head thrown backward. If a person with opisthotonos lies on his or her back, only the back of the head and the heels touch the supporting surface.
