What does Hautant's test evaluate?

Hautant's test is specifically designed to assess whether dizziness is of vestibular or vascular origin. The test involves having the patient sit or stand with their arms extended and eyes closed. The clinician observes if any abnormal movements or changes occur when the position is held. This response can help differentiate between neurological or vascular causes of dizziness, as certain movements or positions may exacerbate symptoms related to vestibular dysfunction while others may indicate vascular issues.

The focus on discerning the nature of dizziness makes this test unique and pertinent in clinical practice, particularly for patients presenting with balance issues or unexplained dizziness. By accurately identifying whether the cause is vestibular or vascular, appropriate interventions can be determined, ensuring that the patient receives the correct treatment based on the underlying issue.
