For the VNG test, goggles are placed on the patient while an infrared camera connected to a computer measures nystagmus (eye movement) during different types of stimulation (visual, positional and caloric). A pattern of eye movement is recorded, producing data from which the practitioner is able to determine whether the pathology is of central or vestibular origin, whether it is ocular-motor, or whether the patient has benign paroxysmal positional vertigo (BPPV).
VNG analyzes the cause of a patients
balance disorders by testing oculo-motor responses to
visual, positional and caloric stimulus. The patients
oculo-motor response is measured against objective
criteria, and the practitioner receives an objectively
measured assessment that differentiates between
peripheral and central vestibular pathology. Results
appear on the screen and a printout of normative data
and the patients results are generated for the patients
Most Physicians utilize the
Interpra reporting software which is compatible
with MedTrak VNG equipment to produce full
narrative reports which are organized for the
clinician and include the normals for each
testing procedure. The Interpra system allows the technician to transfer the data electronically to a
secure, proprietary, HIPAA Compliant, online site containing
our specific VNG algorithm for instantly organized reports which then allow the practitioner to easily review the test results and make a differential diagnosis.
The VNG test is conducted by a trained and proficient technician, takes approximately 40-60 minutes to conduct, and a full narrative report can be generated (utilizing Interpra) which includes impressions and recommendations.
This procedure is currently being performed by many prestigious medical practices across the nation. Resources are available to contact for discussion of programs from a research, clinical, business and revenue perspective.
