Vestibular (Dizziness) Assessments
Dizziness is the second most common complaint, after pain syndromes in MVA clients suffering from head trauma or whiplash injury. Vertigo and imbalance can significantly contribute to patients’ disability and quality of life.
Historically, dizziness was considered a subjective complaint that was challenging to measure or document, however objective diagnostic methods included in our Vestibular assessment, can help to verify and quantify degrees of functional impairment and disability. The methods used are Video Nystagmography (VNG) Video Head Impulse Testing (vHIT).
PDAC is now offering Vestibular Medical-Legal Assessments by Vitaly Kisilevsky (IMG MD [Europe], PhD, LMCC) and Dr. Xerxes Punthakee (MD, FRCSC), specializing in Otolaryngology – Head and Neck Surgery (Ear, Nose & Throat [ENT]). Objective laboratory neuro-physiological testing of MVA clients provides potential evidence of trauma and weakness to the vestibular system which may be relevant to clients with head and neck trauma, and nervous system injuries.
VNG is a test for evaluating patients with dizziness and is considered a gold standard by many in the assessment of vestibular function. It tracks eye movements in relation to stimuli and activities, which allows us to gather objective information on the inner ear.
vHIT is a new objective test designed to evaluate high frequency performance of the balance system and to diagnose a cause of dizziness triggered by fast movements and head turns. This test is based on high frequency video recordings of eye movements in high- velocity head turns, which can otherwise not be observed clinically. vHIT allows improved diagnostics for previously undetectable high frequency vestibular deficit, and it is becoming a new standard in comprehensive testing for the assessment of dizziness and balance problems.
