Which sign would not be indicative of Kernig's sign in a physical exam of a child?

• A. Pain with neck flexion
• B. Resistance to flexing the hip
• C. Resistance to extension of the knee
• D. Difficulty standing

Answer: (D)

Kernig's sign is a clinical test used to assess meningeal irritation, which is commonly associated with conditions like meningitis. The classic presentation of Kernig's sign includes resistance to flexing the hip and difficulty extending the knee when the hip is flexed. When evaluating the signs related to Kernig's sign, the presence of pain with neck flexion indicates meningeal irritation, aligning with the overall clinical picture one would expect. Similarly, resistance to flexing the hip and resistance to extension of the knee are direct manifestations of Kernig's sign, highlighting an abnormal reaction during the examination that suggests potential meningeal inflammation. Difficulty standing, on the other hand, does not specifically indicate Kernig's sign. While a child may exhibit difficulty standing for numerous reasons—such as pain, weakness, or other neurologic issues—this sign does not directly reflect the hallmark signs of meningeal irritation that Kernig's sign is designed to elicit. Therefore, it does not belong in a group of findings that would indicate the presence of Kernig's sign during a physical examination.
