From 1 to 4 percent of normal patients will test positive for Trousseau's sign of latent tetany. [2] This sign may be positive before other manifestations of hypocalcemia such as hyperreflexia and tetany, as such it is generally believed to be more sensitive (94%) than the Chvostek sign (29%) for hypocalcemia.
The Chvostek sign (/ ˈ k v ɒ s t ɪ k /) is a clinical sign that someone may have a low blood calcium level (a decreased serum calcium, called hypocalcemia).The Chvostek sign is the abnormal twitching of muscles that are activated (innervated) by the facial nerve (also known as Cranial Nerve Seven, or CNVII).

Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic. [1] [3] [6] Mildly low levels that develop slowly often have no symptoms.
Cerebellar signs usually involve balance and coordination, and may include: [citation needed] cerebellar ataxia a gait with a broad base; the patient falters to the side of the lesion ; inability to coordinate fine motor activities (intention tremor), e.g. "past-pointing" (pointing beyond the finger in the finger-nose test)
Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is an autosomal recessive late-onset heredodegenerative multisystem neurological disease. The symptoms include poor balance and difficulty walking. Chronic cough and difficulty swallowing may also be present.
A diagnosis for cerebellar degeneration is regarded after any of the aforementioned signs and symptoms surface. For genetically classified forms of cerebellar degeneration, genetic testing can be carried out in order to confirm or deny the diagnosis, where this form of testing is only possible if the gene responsible for the cause of the ...
A positive Hoffmann's reflex and finger jerks suggest hypertonia, but can occur in healthy individuals, and are not useful signs in isolation. In cerebellar diseases, the reflexes may be pendular, and muscle contraction and relaxation tend to be slow, but these are not sensitive or specific to cerebellar signs. [4] [5]
