In 1909, Brudzinski reported that, for patients with bacterial or tuberculous meningitis, Kernig’s sign was 57% sensitive, and Brudzinski’s nape-of-the-neck sign was 96% sensitive [5]. Since then, the presence of these clinical signs has been interpreted as evidence of meningeal inflammation.
What is tripod sign?
Tripod sign, also known as the “Amoss’s sign,” is a useful sign of meningeal irritation. It is used for diagnosing conditions like meningitis, subarachnoid hemorrhage, and poliomyelitis. Cerebral and meningeal inflammation were first described in detail by Willis (1685) and Morgagni (1761).

What is Kernig and Brudzinski signs?
Kernig’s is performed by having the supine patient, with hips and knees flexed, extend the leg passively. The test is positive if the leg extension causes pain. The Brudzinski’s sign is positive when passive forward flexion of the neck causes the patient to involuntarily raise his knees or hips in flexion.
How is the Brudzinski test used for meningitis?
Brudzinski’s sign: Position the patients supine and passively flex their neck. This test is positive if this manoeuvre causes reflex flexion of the hip and knee. To test for nuchal rigidity, the examiner flexes the patient’s neck and the test is positive if there is palpable resistance to passive flexion.
How to test for Kernig’s sign in meningitis?
To test for Kernig’s sign, the patients are positioned supine with their hips flexed to 90°. Kernig’s sign is present if there is pain on passive knee extension. To elicit Brudzinski’s sign, the patients lie supine and their necks are passively flexed by the examining clinician.
How to test for meningitis in the neck?
In each test, the clinician aims to stretch the meninges and thus elicit features of meningeal irritation ( box 2 ). Neck stiffness: Passively flex the patient’s neck. This test is positive if there is palpable resistance. Kernig’s sign: Position the patients supine with their hips flexed to 90°.
