Kernig's sign (Kemig S Sign)

Kernig's sign (Kemig S Sign) is one of the key signs of meningitis, an inflammation of the meninges that can be caused by a bacterial, viral or fungal infection. The name of the symptom comes from the name of the German neurologist Walter Kernig, who first described it in 1884.

The essence of the symptom is that when trying to stretch the legs at the knee joints, the patient experiences severe pain and resistance in the leg muscles. This occurs because inflammation of the meninges leads to increased intracranial pressure, which can cause various neurological symptoms.

To test for Kernig's sign, the patient is placed on his back and his knees and hips are bent at right angles. Then they try to stretch their legs up at the knee joints, holding them by the hips. If the patient experiences pain and resistance in the muscles, then the Kernig sign is positive, which is an unfavorable prognostic sign.

Kernig's sign is not specific to meningitis and may occur with other conditions such as subarachnoid hemorrhage or brain tumors. However, in combination with other symptoms such as neck stiffness, headache, nausea and vomiting, the Kernig sign can help the doctor make the correct diagnosis and begin timely treatment.

Overall, the Kernig sign is an important neurological sign that can help diagnose meningitis and other brain diseases. If you suspect that you have meningitis or other neurological diseases, you should consult a doctor and undergo appropriate examination and treatment.

Kernig's Sign: Understanding and Diagnostic Significance

In medical practice, there are many methods and signs used to diagnose various diseases. One such sign, commonly used when meningitis is suspected, is known as Kernig's sign or Kemig S Sign. This symptom is an important indicator of inflammatory processes associated with the brain and cerebrospinal fluid, and can help doctors make the correct diagnosis and begin the necessary treatment.

The description of Kernig's symptom is as follows: when it occurs, the tendons of the leg muscles become so stiff that the patient is unable to extend his legs at the knees if they are held by the hips at a right angle to the body. This test is performed by slowly and smoothly raising the patient's leg to a bent knee position and then attempting to passively extend the leg to a fully straight position. If the Kernig sign is positive, the patient experiences severe pain and resistance when trying to straighten the legs.

Kornigov's sign is named after Vladimir Kernig, a German neurologist who first described this sign in 1882. The appearance of Kernig's symptom is explained by the presence of inflammation around the spinal cord and its membranes, which leads to irritation of the radicular nerves and pain when bending and trying to straighten the legs.

Kernig's symptom is highly specific, that is, its occurrence almost always indicates the presence of inflammatory processes such as meningitis. However, it is not a sensitive sign because it may be absent in some patients with meningitis or present in other diseases. Therefore, the Kernig sign is usually combined with other clinical and laboratory methods to achieve a more accurate diagnosis.

If meningitis or other inflammatory processes are suspected, doctors may perform additional tests, such as a cerebrospinal fluid tap or CT scan of the head, to confirm the presence of inflammation and identify its cause. Rapid diagnosis and appropriate treatment are important components in the fight against inflammatory diseases, as they can progress quickly and pose a threat to the patient's life.

In conclusion, Kernig's sign is an important sign used by doctors when they suspect meningitis and other inflammatory processes. This symptom is based on the observation of stiffness of the tendons of the leg muscles and the patient's inability to extend the knees at right angles to the body. Kernig's sign has high specificity, but is not always a sensitive sign. Using it in combination with other clinical and laboratory research methods allows doctors to more accurately diagnose inflammatory diseases and prescribe appropriate treatment. Rapid diagnosis and early treatment are important measures to prevent complications and improve the prognosis for patients.
