What does a positive Brudzinski sign indicate?

• A. Extension of the arms when neck is flexed
• B. Flexion of the hips and knees when the neck is flexed
• C. Increased resistance to arm extension
• D. Pain during physical activity

Answer: (B)

A positive Brudzinski sign is clinically significant as it indicates meningeal irritation, which can be associated with conditions such as meningitis. When the neck is flexed and both the hips and knees involuntarily flex in response, this reflexive action suggests irritation of the meninges surrounding the central nervous system. Meningeal irritation often occurs when there is inflammation or an infection in the meninges, leading to a protective response of the nervous system. This sign is frequently assessed as part of a neurological examination, especially in cases where there is a concern for meningitis or other neurological conditions. Therefore, the presence of a positive Brudzinski sign increases suspicion for an underlying serious condition that requires further evaluation and possible intervention. Understanding this helps health practitioners in diagnosing conditions that can present with significant neurological implications.
