Table 1 Characteristics of patients with posturing Clinical and laboratory characteristics, and changes during admission Patients with no posturing (n = 254)
What is the prognosis of opisthotonic posturing?
In addition to being a sign of lower brainstem compression, the particularly high mortality in patients with opisthotonic posturing may be a result of the combined effects of a more severe encephalopathy with raised ICP, repeated seizures and severe metabolic acidosis.
What are the treatment options for opisthotonos?
Treatment options depend on the underlying cause of opisthotonos. Commonly used treatment plans include: Antibiotics for bacterial based infections, such as meningitis and tetanus. Antibiotics are also prescribed to prevent infection or further bacterial infections after surgery.

What is decerebrate posture and how does it affect the brain?
Decerebrate posture can be explained as an abnormal posture of the body, resulting in straightening out of the legs and arms, while the toes point downward, and the neck arch backwards. Along with that, muscles get rigid and tight, causing extreme brain damage. Hence, the decerebrate posture usually leads to a severe injury to the brain.

People who have decorticate rigidity should get medical attention right away. Decorticate posturing is a sign of damage to the nerve pathway between the brain and spinal cord.
