DX200 VNG / Eye-Tracking
Spryson is driven by an overarching desire to create the most precise and powerful VNG and Eye-Tracking technology in the world. The DX200 series is the platform of choice for research facilities and the most modern clinicians.
DX200 Hardware
The DX200 is an industry-leading VNG platform featuring a virtual 3D display integrated into a compact and highly portable package. In addition to the standard battery of VNG tests, the virtual 3D environment provides advanced tests, not available elsewhere, that are useful in concussion, mTBI, and the neurologic patient populations.
The DX200’s precision and data gathering capability are unsurpassed. At a 250 Hz sampling rate and a spatial resolution of 0.01° (horizontal and vertical) and 0.1° (torsional), it can see what other systems miss—precision matters in research and patient care.
To speed up and standardize data collection, our VEST software features automated voice instructions and the ability to group similar tests together, allowing them to be performed in a single block.
VEST includes FDA-cleared and published normative ranges. Clinicians and researchers in sports medicine and concussion management utilize the DX200’s portability to perform preseason baseline assessments and post-concussion follow-up evaluations.

DX Series Software
Spryson’s neuro-otologic analysis software (VEST™) offers a visual and easy to use interface. All NOTC and VNG tests are built into one software platform, eliminating the need for multiple software packages.
Key Features
- Clinical utility with research level power to create protocols and custom tests
- Clinical speed and ease of use for quick patient evaluation and accurate analysis
- Real time binocular data and stimulus feedback including video image with no lag time
- Easy to understand data reporting for patient files with normative ranges clearly designated for each test
- Separate examiner and administration login with password protection
Clinical Test Menu
Spryson’s Brain Health Assessment includes a comprehensive menu of oculomotor, cognitive, vestibular and reaction time tests, including tests not offered in other integrated systems such as vergence and reaction time. This includes a diversity of data-rich variables and analytics. The Spryson Platform allows clinicians and researchers the ability to compare individual results over time and to benchmark against FDA cleared normative data.
A Quantum Shift in Brain Health and Wellness
Spryson is on a mission to create a quantum shift in the clinical approach to neurodegenerative disease while simultaneously revolutionizing brain health and wellness.
