No, the gallbladder is usually not movable in positive Courvoisier's sign. Positive Courvoisier's sign refers to a palpable, non-tender, enlarged gallbladder in the presence of obstructive jaundice. This sign is typically associated with an obstruction of the common bile duct by a mass or tumor, which prevents the flow of bile from the gallbladder. In this case, the gallbladder may become distended and enlarged due to accumulation of bile. However, the gallbladder itself is not typically freely movable or palpable in positive Courvoisier's sign.
