Vestibular and Balance Laboratory

vestibular lab vestibular lab vestibular lab vestibular lab

The Vestibular and Balance Laboratory (VBL) is housed in the Department of Audiology and Speech Pathology. The VBL is focused on clinical-translational research with the goal of producing research data with short-interval application for clinical vestibular evaluation and management. The VBL is equipped with:

  • Videonystagmography
  • Electronystagmography
  • Evoked Potentials including:
    • Vestibular evoked myogenic potentials (cervical and ocular)
    • Auditory brainstem response
    • Electrocochleography
  • Rotational chair
  • Caloric irrigation
  • Video-head-impulse equipment
  • Balance function protocols

The VBL contains IBM-compatible computers plus related hardware. Software is available to carry out all current forms of data analysis. The VBL is connected to the University's mainframe computers via an Ethernet network. Both Ph.D. and Au.D. level students rotate through the laboratory.

  • Mental tasking during rotary chair testing
  • Auditory suppression of the vestibulo-ocular reflex
  • Cervical and ocular vestibular evoked myogenic potentials in adults with sensory hearing loss
  • Categorizing artifact during pediatric oculomotor study using video-oculography.
  • The effects of cochlear implantation on clinical vestibular measurement in the pediatric population
  • Factors influencing number of falls in a cognitively impaired adult population

The Vestibular and Balance Laboratory is always active with research participation opportunities. Please contact the lab coordinator, Dr. Steven M. Doettl at or call 865.974.5453 to explore opportunities to participate!
