Jolt accentuation of headache: can this maneuver rule out acute meningitis?

Area of Science:

• Neurology
• Infectious Diseases
• Emergency Medicine

Background:

• Acute meningitis is a critical medical condition requiring prompt diagnosis and treatment.
• The Jolt accentuation of headache maneuver is a simple clinical test for meningitis, but its diagnostic value is debated.

Purpose of the Study:

• To evaluate the diagnostic accuracy of the Jolt accentuation of headache maneuver in patients with suspected acute meningitis.
• To compare the Jolt maneuver's effectiveness against other clinical signs like nuchal rigidity, Kernig's, and Brudzinski's signs.

Main Methods:

• A study was conducted on 227 adult patients presenting with suspected acute meningitis at an emergency ward.
• Cerebrospinal fluid (CSF) analysis was performed to confirm meningitis.
• The Jolt maneuver, nuchal rigidity, Kernig's, and Brudzinski's signs were assessed for diagnostic accuracy.

Main Results:

• Of 227 patients, 64 (28.2%) had meningitis confirmed by CSF analysis.
• The Jolt maneuver was positive in 62.5% of meningitis patients, with a sensitivity of 62.5% and specificity of 88.3%.
• Kernig's sign had the highest positive likelihood ratio (6.79), while nuchal rigidity had the lowest negative likelihood ratio (0.39).

Conclusions:

• A positive Jolt maneuver in adult patients with fever and acute headache suggests meningitis and supports the need for CSF examination.
• Negative Jolt maneuver results should not be used to exclude the diagnosis of meningitis.
• The Jolt maneuver is a valuable, though not definitive, tool in the emergency diagnosis of acute meningitis.
