What is Nuchal Rigidity?

Nuchal Rigidity is when a patient is unable to flex his or her head forward due to an un-natural rigidity of the neck muscles.

Nuchal Rigidity is often associated with Meningitis and any irriation of the meninges, such as a Subarachnoid Haemorrhage with blood in the meninges.

Nuchal Rigidity is a primary sign of Acute Meningitis.
