Nystagram Interactive Video Nystagmography
Testing System

The Nystagram is a videonystagmography system that records and displays nystagmic eye movement for the purpose of evaluating vestibular disorders. The unique head monitoring systems uses a series of accelerometers and sensors in the comfortable VNG goggles to actively supervise small movements and variations of patient position. This allows real time patient direction and ensures accuracy of data. The comprehensive reports include notations to illustrate patient head positioning and provide confidence in test data collection.

The Nystagram configuration is small and portable. It only requires a small footprint for ease of use in any location. Clinical setting, hospital Emergency Room or sports locker room, the Nystagram offers flexibility with any patient stimulus monitor size.

This Windows 7 based system offers HIPAA and HITECH security options and the ability to integrate with EMR systems. The software offers the ability to configure multiple protocols for customized test batteries, based on the preferences of the clinician and the needs of the patient.

Nystagram Features

Three aspects of patient position are important to ensure accurate results from the various tests that the Nystagram offers. The three Patient Position Alerts below are displayed initially during patient setup and throughout the testing, in order to provide feedback to the test administrator. For optimal test results, it is important that these alerts are followed and that the patient is directed to correct their position accordingly.

Patient Position (Orientation with respect to Monitor): Ensures that the proper patient position relative to the Visual Stimulus Monitor is achieved. Provides an alert if the patient needs to adjust sitting position.

Head Angles:

Ensures that accurate vertical and horizontal tracking of the eyes is achieved. Provides an alert if the head needs to be tilted, raised, or lowered.

Head Movements:

Ensures that the patient is remaining still enough for accurate measurements of eye movement. Provides an alert if head movement is interfering with testing.
