Diagnostic Test for Vestibular disorder

Vestibular disorders can lead to balance and spatial orientation problems, causing symptoms such as dizziness, vertigo, and falls. To accurately diagnose such disorders, we conduct a comprehensive series of tests to analyze your vestibular system, which is integral to maintaining balance and coordinating movements. The following tests provide vital information about your balance, spatial awareness, and coordination abilities:

  1. Basic Balance Test: This initial test is conducted to evaluate your overall balance. Your balance and stability are assessed under different conditions such as standing with your eyes open and closed, and on varying surfaces. It provides a basic understanding of your ability to maintain balance and stability under various circumstances, thus helping in identifying any significant anomalies.

  2. Modified Clinical Test of Sensory Interaction and Balance (m-CTSIB): Also known as Dynamic Posturography, this test assesses your ability to maintain balance under changing sensory conditions. The test measures your body movements and shifts in the center of pressure while you stand on a force plate or a balance platform. By changing the conditions – for instance, eyes open/closed or standing on firm/soft surfaces – we observe your balance adjustments in response to the sensory inputs. The results of this test provide valuable information about your postural stability and your ability to manage balance control under varying sensory environments.

  3. Video-nystagmography (VNG): The VNG test is an advanced diagnostic tool that uses infrared goggles to assess the inner ear and central motor functions. It helps us examine the coordination between your eyes, body, and brain – the triad responsible for maintaining balance. During the VNG test, we observe your eye, head, and body movements under different conditions. Any irregularities in these patterns can indicate an issue with your vestibular system.

  4. Video Head Impulse Test (vHIT):  The vHIT is a crucial diagnostic test for evaluating the function of your vestibular system. It involves analyzing your eye movements in response to quick, unexpected head movements. This test is vital in diagnosing various vestibular disorders as it helps detect abnormalities in the vestibulo-ocular reflex, a system crucial for maintaining clear vision and balance during head movements.

  5. Dynamic Visual Acuity Testing (DVA): DVA test is a unique way of assessing your visual acuity during dynamic conditions. While conventional visual tests evaluate static vision, DVA simulates movement to understand how well your vision adapts during motion. It is especially relevant for people with vestibular disorders as it provides insights into the functional status of the visual-vestibular system, which is responsible for maintaining visual focus during head movements.
