Kernig's sign (after Waldemar Kernig (1840–1917), a Russian neurologist) is positive when the thigh is flexed at the hip and knee at 90 degree angles, and subsequent extension in the knee is painful (leading to resistance).[1] This may indicate subarachnoid hemorrhage or meningitis.[2] Patients may also show opisthotonus—spasm of the whole body that leads to legs and head being bent back and body bowed forward.[3]
