Opisthotonus or opisthotonos (from Ancient Greek: ὄπισθεν opisthen, meaning 'behind', and τόνος tonos, meaning 'tension') is a neurological condition characterized by extreme hyperextension and spasticity. In this state, an individual's head, neck, and spinal column enter into a pronounced arching or bridging position.

Causes

Opisthotonus can be caused by a variety of conditions, including:

• Meningitis
• Severe brain or spinal cord injuries
• Tetanus
• Neuroleptic malignant syndrome
• Certain metabolic disorders

Symptoms

The primary symptom of opisthotonus is the extreme backward arching of the head, neck, and spine. Other symptoms may include:

• Muscle stiffness and spasms
• Difficulty breathing
• Pain

Diagnosis

Diagnosis of opisthotonus involves:

• Neurological examination
• Medical history review
• Diagnostic imaging like MRI or CT scans
• Lumbar puncture, if meningitis is suspected

Treatment

Treatment focuses on managing the underlying cause and may include:

• Medications to relieve muscle stiffness and spasms
• Supportive care for breathing and feeding difficulties
• Physical therapy
