Nuchal rigidity

Definitions
Resistance of the extensor muscles of the neck to being bent forwards (i.e., impaired neck flexion) as a result of muscle spasm of the extensor muscles of the neck. Nuchal rigidity is not a fixed rigidity. Nuchal rigidity has been used as a bedside test for meningism, although its sensitivity for this purpose has been debated. Meningism is resistance to neck flexion due to painful spasm of extensor muscles resulting from meningeal irritation. The diagnosis of meningism is made in someone whose symptoms simulate meningitis, but in which no actual inflammation of these membranes is present. Nuchal rigidity can thus be observed in individuals with meningitis or with meningism.
