Manifested by persistent flexion of the upper extremities, bringing them to the torso and extending them, rotation of the lower extremities. This type of posture usually means, that there are serious and severe brain damage (this is a common cause of decorative rigidity).
It may alternate with another type of disorder, called decerebrate rigidity. A person may have decorative rigidity on one side of the body and decerebrate rigidity on the other side..

- Angiography of the brain (injection of a radiopaque dye and x-rays of blood vessels in the brain)
- CT or Head MRI
- EEG (brain wave testing)
- Monitoring of intracranial pressure (ICP)
- Poyasnichnaya puncture for collection of cerebrospinal fluid
The prospects for recovery depend on the cause of the decerebrate rigidity.. The victim may have severe damage to the brain and nervous system, which may lead to:
- To whom
- inability to communicate
- paralysis
- convulsions
