Mechanism
“maneuvers used to elicit meningeal signs produce tension on inflamed and hypersensitive spinal nerve roots, and the resulting signs are postures, protective muscle contractions, or other movements that minimize the stretch and distortion of the meninges and roots”

Diagnostic value
a. Kernig's sign (Thomas et al 2002)
SN 5% SP 95% PPV 27% NPV 72%
b. absence of fever, neck stiffness, and altered mental status (DeJong)
exclude meningitis (SN 99%)

Nuchal rigidity
a. relax neck muscles by supine patient to edge of bed& allow head to hang outside bed
b. place your hand under patient's head & try to flex neck, touch chin to chest
c. resistance implies diffuse irritation of cervical nerve roots from meningeal

Kernig's sign
a. flex hip&knee on 1-side while patient is supine
b. now, extend knee w/ hip still flexed
c. +, if hamstring spasm results in pain in post thigh & difficulty w/ knee extension
d. severe inflammation of meninges, the opposite knee may also flex

Patient is asked to sit up in bed. Health, sits up w/o supporting himself
Meningeal irritation: patient tries to sit up by supporting himself w/ his hands placed far behind him in bed, to take the weight off the spine and prevent its flexion.
