Other signs include the presence of positive Kernigs sign or Brudziński sign. Kernigs sign is assessed with the person lying supine, with the hip and knee flexed to 90 degrees. In a person with a positive Kernigs sign, pain limits passive extension of the knee. A positive Brudzinskis sign occurs when flexion of the neck causes involuntary flexion of the knee and hip. Although Kernigs sign and Brudzinskis sign are both commonly used to screen for meningitis, the sensitivity of these tests is limited. They do, however, have very good specificity for meningitis: the signs rarely occur in other diseases. Another test, known as the "jolt accentuation maneuver" helps determine whether meningitis is present in those reporting fever and headache. A person is asked to rapidly rotate the head horizontally; if this does not make the headache worse, meningitis is unlikely.Other problems can produce symptoms similar to those above, but from non-meningitic causes. This is called meningism or pseudomeningitis.Meningitis caused by the bacterium Neisseria meningitidis (known as "meningococcal meningitis") can be differentiated from meningitis with other causes by a rapidly spreading petechial rash, which may precede other symptoms. The rash consists of numerous small, irregular purple or red spots ("petechiae") on the trunk, lower extremities, mucous membranes, conjunctiva, and (occasionally) the palms of the hands or soles of the feet. The rash is typically non-blanching; the redness does not disappear when pressed with a finger or a glass tumbler.
