@daily.dose.of.med: The Trousseau sign is a simple physical examination finding that can reveal hidden low calcium levels in the blood. When a blood-pressure cuff is inflated on the arm for a few minutes, a person with increased neuromuscular excitability may develop an unusual hand spasm, with the wrist and fingers bending into a characteristic position. This happens because low calcium makes nerves and muscles more sensitive and easier to activate. Interestingly, the Trousseau sign can sometimes appear before a person develops obvious symptoms of hypocalcemia, making it a useful bedside clue for healthcare professionals.
