Clinical Vestibular Lab


The Clinical Vestibular Lab serves two primary goals: 1.) to provide clinical services in the assessment of balance and dizziness and, 2.) to conduct research in vestibular physiology in both health and pathology. Clinically, the Vestibular Lab sees patients of all ages with complaint of imbalance and/or dizziness. We provide comprehensive balance and vestibular evaluations as well as vestibular rehabilitation and fall prevention. The primary goal of the research program is to understand the underlying physiology of the vestibular system in health and disease and relate this to improving diagnostic testing and treatment.


The Clinical Vestibular Laboratory consists of the following major equipment: Two ENG/VNG systems with water caloric irrigators, an ISCAN 3-D Eye Tracking System, a Rotary Chair with Subjective Visual Vertical (SVV) and manual, lateral off-axis rotation capability, a NeuroCom SMART Equitest and InVision with long force plate, allowing the following assessments: Computerized Dynamic Posturography (CDP), Postural Evoked Responses (PER), Dynamic Visual Acuity (DVA), Gaze Stabilization Test (GST),  Cervical and Ocular Vestibular Evoked Myogenic Potential (c- and oVEMP) Testing, among others.

An additional evaluation room is located at the west hospital and is equipped with an ENG/VNG system with a water caloric irrigator. Cervical and ocular VEMP testing is also available at the west hospital.


The laboratory is directed by Kristen Janky, Au.D., Ph.D., with Bethami Grossman, Au.D., Ashley Halbach, Au.D., Natalie Lenzen, Au.D., Megan Thomas, Au.D., Josh Olmstead, Au.D., and Nathan Williams, Au.D., assisting with clinical vestibular services. Diane Givens, M.S., PT, NCS provides vestibular rehabilitation services.

Specific Areas of Research

  1. Improving pediatric vestibular assessment and rehabilitation.
  2. Improving VEMP test performance in specific patient populations.
  3. Collaboration with the Vestibular Genetics Lab in understanding the molecular cause of BPPV to improve treatment methods.
  4. Improving diagnostic sensitivity for patients with dizziness and migraine.
