Kernig sign is most commonly associated with which condition?

Explanation:
Kernig sign indicates meningeal irritation. When the hip is flexed to 90 degrees, trying to extend the knee beyond a point causes resistance and pain if the meninges are irritated, typically from meningitis. This direct link to meningeal inflammation makes meningitis the condition most strongly associated with a positive Kernig sign. Migraines, strokes, and tension headaches don’t involve the same meningeal irritation pattern, so Kernig sign isn’t a characteristic finding in those conditions.
