These signs test for irritation of the meninges, which happens with meningitis. When the meninges are inflamed, maneuvers that stretch or bend the neck or stretch the nerves along the spine provoke symptoms. Kernig sign is observed when a patient lies on the back, the hip is flexed to 90 degrees, and you try to straighten the knee; pain and resistance with extension indicate meningeal irritation. Brudzinski sign is observed when passive flexion of the neck causes involuntary flexion of the hips and knees, another sign of meningeal irritation. Together, they are classic bedside indicators used to raise suspicion for meningitis and guide further evaluation, especially when fever or neck stiffness is present. Remember they aren’t perfectly specific, but they’re useful in the acute assessment context. The other signs listed relate to different conditions—Tinel and Phalen point to carpal tunnel syndrome; Romberg and Babinski relate to balance or neurologic pathways; Cullen and Grey Turner are associated with pancreatitis or retroperitoneal hemorrhage.
