What is opisthotonos?

Opisthotonos refers specifically to a type of spasm characterized by hyperextension of the body, where the back arches and the head and heels are drawn backward. This condition is often associated with neurological disorders, such as tetanus or certain types of meningitis, where severe muscle spasms occur due to intense contraction of the muscles. The posture can be extremely rigid, indicating distress and a severe neurological response. Recognizing opisthotonos as a spasm is important in medical settings, as it can be a clinical sign that requires immediate attention reflecting underlying medical issues. Understanding this term is crucial for professionals in diagnosing and treating conditions associated with neurological dysfunction.
