Adjusts for make-up and dilated pupils
Real time analysis
Automated 10 second calibration
Automated or manual analysis
Software generated ocular stimuli
Full field of view visual stimuli

 

 

Two solutions

The standard VN415 VNG platform for vestibular analysis and the expanded VO425 VNG for vestibular and oculomotor analysis, each with increasing scope

Detailed balance investigations

Both the VN415 and VO425 are designed for convenient computer aided analysis of position and caloric tests. Rapid data transfer technology enables very high quality video and precise measurements with all results stored in the OtoAccess™ database.

The VO425 is especially tailored for clinics that carry out detailed balance evaluations. It contains all the features of the VN415 plus computer aided analysis of oculomotor tests.

Oculomotor stimuli (only with VO425)

Video projector og LCD monitor compatibility for full-field stimulation during OPK testing, as well as mixed horizontal and vertical pattern during saccade test. Programmable stimuli, including pictures for paediatric patients.

A digital light-bar is optionally available for enhanced mobility.

VNG comes in two versions, VN415 and VO425

 

 

Now also available with ENG

Upgrade your VN415 VNG system with the EN415 preamplifier for vestibular analysis using electrodes instead of video cameras.

Similarly, your VO425 system can be upgraded with the EO425 preamplifier for vestibular and oculomotor analysis using electrodes instead of video cameras.

Switch between ENG and VNG recording in the software

And perform the same tests with ENG as with VNG except rotary chair tests:

How common is dizziness and imbalance?

According to the National Institute of Health ”Over 90 million Americans, age 17 and older, have experienced a dizziness or balance problem”. Dizziness occurs in approximately 1.8 percent of young adults and more than 30 percent of the elderly. Every year, one-half of the population age 65 and over experience falls.

As stated by the Vestibular Disorders Association, children can experience the same vestibular disorders as adults.

How common is dizziness and imbalance and how to treat it!

Remote controlled testing

It is possible to step through the tests using the USB connected foot pedal.

Sharing results

All results are stored in the OtoAccess™ database with abilities for printing detailed colour reports. Results and recordings can also be exported for electronic charting purposes.

Rotational testing and VNG

The Nydiag 200 Rotary Chair provides precisely controlled and reproducible stimuli, full test battery, a number of convenient features when testing and user definable tests.

VEMP

Combine your VNG with VEMP to make a complete balance system.
