Mackenzie Vestibular case studies
Mackenzie Vestibular · Put your knowledge to work in context.
The Mackenzie Vestibular Competency Examination is a knowledge assessment for clinicians who evaluate and treat people with dizziness, imbalance, and vestibular dysfunction - most often physical therapists, but also audiologists, occupational therapists, and other practitioners who build vestibular work into their caseload. It tests whether a candidate can reason from anatomy and pathophysiology through bedside testing and laboratory findings to a defensible plan of care, rather than simply recognizing terminology. Content is organized into eight domains: vestibular anatomy and physiology; pathology and differential diagnosis; the bedside examination (oculomotor, positional, and head impulse testing); laboratory testing such as VNG, vHIT, VEMP, and rotary chair; BPPV and canalith repositioning; vestibular rehabilitation for unilateral and bilateral hypofunction; central vestibular disorders and concussion-related dizziness; and professional practice, safety, and documentation. Preparation works best as a staged review: solidify anatomy and the physiology of the vestibulo-ocular and vestibulospinal reflexes first, then move to bedside techniques, then to interpreting laboratory results alongside clinical findings. The Mackenzie Vestibular case studies are 5 cases and about 2,973 words.
