What is Kernig’s Sign?

A positive Kernig’s Sign indicates that a patient either has a Subarachnoid Haemorrhage (with blood irititating the meninges) or Meningitis.

Kernig’s Sign can be identified when a patient with a decreased level of consciousness (LOC) bends their leg (at the hip) to form a 90 degree angle.

The term Kernig’s Sign was first identified by a German Neurologist by the name of Waldemar Kernig.
