VERTIGO & DIZZINESS ASSESSMENT

Get tested and treated for vertigo & dizziness
Dr Anita Bhandari's Vertigo and Ear Clinic is fully equipped with breakthrough diagnostic equipment and a trained team to investigate the neurotological functioning and coordination of the body's balance system, which is sustained by the signals sent by the eyes, inner ears and proprioceptive system to the brain. Our advanced neurotological team is capable of identifying any disturbance in the well-balanced running of these three systems and diagnosing the underlying causes of vertigo or dizziness.
We conduct the following clinical tests for evaluation of the balance or vestibular system.
Videonystagmography (VNG)
VNG

Videonystagmography (VNG) for evaluation of vestibulo-ocular reflex.

The tests include evaluation of spontaneous nystagmus, smooth pursuit system, saccades, gaze-induced nystagmus, head shaking-induced nystagmus, test for skew deviation, nystagmus induced by hyper ventilation and optokinetic stimulation, Valsalva, caloric testing, and positional testing.

Electronystagmography (ENG)
VOR

This is an investigation to assess the vestibulo-ocular reflex (VOR), which helps maintain the body's balance.

The following tests are recorded to assess peripheral and central vestibular functions of the human body:

  • Spontaneous nystagmus
  • Gaze-evoked nystagmus
  • Saccades
  • Smooth pursuit test
  • Optokinetic stimulation
  • Caloric stimulation
  • Fistula test
Craniocorpography (CCG)
CCG

Craniocorpography(CCG) to evaluate the vestibulospinal reflex, which is responsible for maintenance of balance during gait testing.

Evaluation is done by recording:

  • Romberg test
  • Sharpened Romberg test
  • Tandem walking
  • Unterburger’s test: in this test the following points are evaluated with pictorial reports given to the patient:
    1. - Displacement
    2. - Sway
    3. - Angle of deviation
    4. - Body axis spin.
Subjective Visual Vertical Test (SVV)
SVV

Subjective visual vertical test (SVV) is conducted to determine a patient's ability to perceive the verticality of a viewed object (dependent on inputs

from visual, vestibular and somatosensory systems along with a functioning central nervous system) and to detect abnormal subjective tilt. At Dr Anita Bhandari's Vertigo and Ear Clinic both static and dynamic SVV are carried out to

  • Differentiate peripheral from central vestibular disorders
  • Decide side of peripheral vestibular insult
  • Diagnose compensated vestibular disorders
  • Evaluate patients of chronic dizziness
  • Do follow up of vertigo patients to assess improvement.
Dynamic Visual Acuity (DVA)
DVA

Dynamic Visual Acuity (DVA) Test evaluates the ability of the patient to focus on moving images

and to stabilize images on the retina during head movement. The DVA test helps to diagnose vestibulotoxicity and VOR dysfunction.

Centre of Balance
Evaluation

Evaluation of centre of balance and maintenance of posture.

services

Diagnosis of the underlining cause of vertigo requires a battery of tests and, usually, a multidisciplinary approach by a panel of ENT, neurologist and psychiatrist.
