Technology in the hands of trained, competent practitioners lead to improved outcomes.  Needs of the research community differ from those in clinical practice.  Research findings can frequently be integrated into clinical practice if the techniques are easily reproduced and can be demonstrated to lead to improved outcomes. The companies who manufacture the following technology are among the premier companies who have been meeting the needs of the noted specialists in key research and clinical settings around the world. We believe them to the be the best in class for each of the categories.

Electronystagmography

Artificial stimulation of the vestibular apparatus produces nystagmus, past-pointing falling and autonomic responses such as sweating, vomiting, hypotension and bradycardia nystagmus. the most useful response, can be monitored visually or more reliably by recording changes in the corneoretinal potential.  The most reproducible and reliable monitoring of artificial stimulation of the vestibular apparatus producing nystagmus is provided by electronystagmography.

 

Rotational (Barany) Chair

The Barany (or Rotary) Chair is used for neuro-otologic testing. Testing focuses on the vestibular ocular reflex as well as the visovestibular interaction.  Abnormal patterns can help localize lesions within the central pathways.

 
Computerized Dynamic Posturography

Computerized Dynamic Posturography (CDP) is a unique assessment technique used to objectively quantify and differentiate among the wide variety of possible sensory, motor, and central adaptive impairments to balance control. As such, CDP is complementary to clinical tests designed to localize and categorize pathological mechanisms of balance disorders. CDP can identify and differentiate the functional impairments associated with the pathological processes. By itself, CDP cannot diagnose pathology or site-of-lesion.

 

Dynamic Visual Acuity/Gaze Stabilization
Dynamic Visual Acuity (DVA) Test Quantifies the impact of vestibular ocular reflex (VOR) system impairment on a patient's ability to perceive objects accurately while moving the head at a given velocity on a given axis. Gaze Stabilization Test (GST) Quantifies the range of head movement velocities on a given axis over which a patient is able to maintain an acceptable level of visual acuity.
Audiometric Assessment
The audiologic evaluation is required for early diagnosis in many cases of dizziness. The components of an audiologic assessment are the audiogram, acoustic immittance audiometry, tympanometry, auditory brain-stem response (ABR), electrocochleography (ECoG) and Otoacoustic emission (OAE). The individual test are selected based on the patient history developed by the clinician.
