Step-by-step explanation:

Carvallo's sign refers to pain in the neck or back that occurs when a patient with meningitis attempts to extend the leg at the knee while the thigh is held in 90 degrees of flexion. This sign is used as an indication of meningeal irritation. It is named after Eduardo Carvallo, a Chilean physician who first described the sign in patients with meningitis.
