VIDEO HEAD IMPULSE TEST
Introducing the SYNAPSIS VHIT (Video Head Impulse Test) - Designed and developed with the help of the visionary and world-renowned otologist Dr. Erik Ulmer.
Synapsys VHIT is a unique product in balance testing. Thanks to a revolutionary remote camera system, it is the first and only video VHIT that does not require the use of goggles or any kind of device to be placed on patient’s head.
Key benefits of the Synapsys VHIT (Video Head Impulse Test)
- Fast test : 5 minutes to test the 6 canals and detect saccades (overt and covert) and to obtain a complete and relevant analysis
- Non-invasive test : no mask or device on patient’s head thanks to goggleless camera
- Independent analysis of the 6 semi-circular canals through fast head movements
- Simultaneous observation of eye and head movements thanks to goggleless camera
- Manoeuvres simple to carry out : automatic detection of the tested canal and visual information given by software in real time and manoeuvre guide
SEPARATE ANALYSIS OF EACH SEMICIRCULAR CANALS
U-VHIT is a revolutionary analysis of the six semicircular canals. This examination allows a separated analysis of the response of each canal by making rapid head movements.
In cases of pathologies that affect both low and high frequencies, the lateral Head Impulse Test gives the same information as the caloric tests, but much faster.
The U-VHIT test highlights the associations between affected canals. It also helps to detect diseases that only affect the vertical canals.
PHYSIOLOGICAL MOVEMENTS, NON-INVASIVE TEST FOR THE PATIENTThe U-VHIT system uses a unique technology that makes it very easy to use: a camera is positioned 1 meter far from the patient and frames his face, while the doctor performs the maneuvers on his head. Unlike other VHIT systems, the U-VHIT does not require the patient to wear a mask, thus increasing his comfort and reducing the artifacts introduced by involuntary movements of the mask.
Thanks to the automatic identification of the examined canal and the visual indications provided by the software, it has never been so easy and fast to obtain correct stimulation.d.
ANALYZE EACH CANAL AT A GLANCE
The U-VHIT test is simple and fast (takes less than 5 minutes) and offers valuable information on the functioning of semicircular canals; it also describes the saccadic phenomena.
The U-VHIT system software simultaneously analyzes head and eye movements, monitors the quality of maneuvers and provides immediate results for each canal during acquisition.
IDEAL TO COMPLETE YOUR VESTIBULAR ANALYSIS
The U-VHIT system is the result of many years of collaboration between Dr. Ulmer, Synapsys and leading research centers.
U-VHIT is available in two upgradeable versions, Screening and Evolution, which cover the different needs. The Screening configuration allows the analysis of the side canals only, while with the Evolution it is possible to analyze lateral, anterior and posterior canals.
Complementary to the VNG examination, the U-VHIT analyses each semi-circular canal at high frequencies. It can therefore detect pathologies that could not be detected with the traditional VNG examination.
