DIFRA VNG SOFTWARE COMPARISON
Baic E-Z VNG Software Compared with Full Featured Premium VNG Software
You have probably noticed from our website that we offer three versions of videonystagmography VNG software technology. So you might be wondering, "Why are there three different VNG devices and
which one works best for me?" Let's start with a basic description of choices. The basic HeadStar E-Z and HeadStar full-featured VNG devices are comprised of a monocular (one) camera system and the NysStar is a full-featured binocular (two) camera VNG device.
If you need to decide which camera choice is best between a one-camera or a two-camera, please refer my blog post entitled, "The Right Choice, One or Two Camera VNG?"
Today, I will assist you with making the correct software choice that fully meets your immediate and long-term needs. Is it basic HeadStar E-Z software or full-featured premium software of HeadStar and
NysStar? To begin deciding what software choice is best for you, what type of patient do you anticipate you will use the VNG to treat?
- Are you interested in expanding your practice with new ancillary services with balance disorder patients, whereby you are evaluating higher falls risk patients to identify, test and treat basic balance disorders?
- Will you be referring more advanced or complex vestibular disorders cases to a neurologist, ENT or AuD?
- Do you or are you interested in testing concussion, TBI or mTBI cases for vestibular disorders?
- Are you vestibular specialist, neurologist, ENT, AuD or similar practice with a high volume of vestibular disorder patients?
Essentially, if you fit into the first two categories, you might consider our more economical basic HeadStar E-Z VNG software. If you fit better within the last two scenarios or you intend to start with the first two, then evolve into the last two categories, you should consider our full-featured, premium HeadStar or NysStar software from the beginning.
Basic HeadStar E-Z VNG Software
Some clients are interested in a more basic, economical VNG device that allows for a good return on investment. The product's manufacturer, Difra Instrumentation, helped us meet those clients' needs by developing the HeadStar E-Z software. HeadStar E-Z software is only available in the monocular device, it is not available in the NysStar binocular device. E-Z software has the same high-definition camera and accurate, exceptional eye-tracking as our full-featured premium software does. You sacrifice nothing in the quality of hardware or accuracy of test results.
The HeadStar E-Z software allows you to conduct all standard VNG tests, just as you can with the full-featured premium software, including:
Calibration, random saccades, smooth pursuit, OPK (horizontal only), spontaneous nystagmus, all gaze positions, active head rotation (AHR) -- vertical and horizontal planes, Dix Hallpike, all body and head positioning and all four caloric tests.
However, to provide a more economical package, the E-Z software does not have some of the advanced software features found on the full-featured premium VNG software. The three main differences are as follows:
- There is no database module included with the HeadStar E-Z. When the battery of tests are completed, the results can be edited, but once saved the reports will become a PDF file. A prompt will warn that after saving the PDF and exiting, the original tests are no longer available, only the saved PDF file. There are three choices of the test results: numerical data, compact and/or detailed reports. I recommend saving all three results. Of course, we always recommend saving the test results to an external hard drive that is connected to your computer, in the event of a computer failure and for improved data security. Additional regular external back-ups of test results are highly recommended to prevent lost data, which cannot be recovered if inadvertently deleted or in the event of computer failure.
- With the E-Z software, it cannot record video of the patient's eyes to review later, after the test is completed. Some physicians like to review the test data and the video recordings at later times,however, with E-Z software, this feature is not available. Not everyone uses this feature, but many clinicians do require it, making the full-featured premium HeadStar and NysStar software the correct choice.
- The E-Z software allows you to change the VNG test sequence, but if you change sequences often, then it will be done manually. As an example, if you are completing all of the tests but not the four caloric tests, you simply need to manually delete the caloric tests during the setup. The E-Z software saves the last sequence run, so if you need to do a full test, including calorics on the next patient you need to manually add back the four caloric tests. With the full-featured premium software, you can enter numerous test sequences into a drop-down menu making the change in test sequencequick and easy.
One last thought on E-Z software. I am frequently asked if it is possible to upgrade from the E-Z to the full-featured premium software. The answer is yes, but it is expensive to do so. My suggestion always is if you feel that you will eventually need or want the full-featured premium software, then it is far more economically feasible to purchase it from the beginning. The increase in cost for the full-featured premium software of HeadStar and NysStar is not significant as a new device, but doubles in cost as an upgrade.
Full-Featured, Premium HeadStar and NysStar Software
The HeadStar and NysStar software allows you to conduct all standard VNG tests, including:
Calibration, random saccades, smooth pursuit, OPK (horizontal and vertical), spontaneous nystagmus, all gaze positions, active head rotation (AHR) -- vertical and horizontal planes, Dix Hallpike, all body and head positioning and all four caloric tests.
Our full-featured premium HeadStar and NysStar software also allows you to complete many additional functions not found in basic, economical HeadStar E-Z software. We already discussed video recording, test sequencing and database capabilities above. If you are needing any of those features, then hands-down the full-feature premium software is your best choice.
In addition, the full-featured premium software has the capabilities for customizable reports, additional tests, such as vertical OPK tests, vHit on Headstar only (not available with NysStar) plus so much more. Other features include a wireless remote control or a foot switch that allows the technician to move through tests easily and efficiently.
If your needs require a wide variety of tests, reporting and post-testing reviews, then our full-featured premium software is what you need. This option will provide years of testing accuracy and quality VNG testing that will meet your needs.
