Chvostecfc S Sign

Tailback's sign or Chvorsteck's sign is a contraction of the facial muscles when the skin is tapped, with an intense symptom accompanied by characteristic tension and an unpleasant sensation reminiscent of an electric shock. It is revealed as a reflex symptom, which is a shortening and rigidity of the muscle when irritated by electric current. This symptom has been described independently by several authors. This feature was first described by Homer, the head of the Massachusetts Hospital, which was located in Massachusetts.

Thus, Hovetzk's symptom is a non-physiological facial reaction that occurs after short-term exposure to a stimulus on certain areas of the body. This can be called a symptom conditionally, because its pathological nature is very doubtful. However, practice shows that when something unpleasant suddenly occurs in the facial area, some contraction of individual muscle groups occurs. Another thing is that in this case there can be no full-fledged reflex reactions and contractile muscle activity. The Chvostback symptom is a fairly common diagnostic sign that can help identify various pathologies. IN
