A positive Chvostek sign is a facial muscle spasm that is elicited by tapping the facial nerve in the region of the parotid gland. Paresthesia occurring in the feet and toes and frequent sharp flexion of the wrist and ankle joints can be signs of hypoparathyroidism but are not part of a positive Chvostek sign. Carpal spasm elicited by pressure applied to nerves of the upper arm is called a positive Trousseau sign.
