BRINGING DIAGNOSTIC ACCURACY AND EFFICIENCY INTO BALANCE TESTING WITH PEOPLE IN MIND Software and hardware improvements make the assessment experience more comprehensible and comfortable for you and your patients. UNDERSTANDING YOUR NEEDS Building on user experiences and relationships with key opinion leaders we have made gold standard vestibular assessment accessible no matter where you test. MEANINGFUL INNOVATION We have refined our way of developing vestibular assessment systems to match the exact needs of clinics, enabling greater precision and faster diagnosis. OUR COMMITMENT, YOUR FUTURE Based on our history and balance testing breakthroughs we develop systems that maintain relevant traditional tests while providing groundbreaking functionality that is changing vestibular testing today, and tomorrow.

Goggle have 2 built-in calibration lasers for patient calibration Standards Video Head Impulse Test Bringing diagnostic accuracy and efficiency into balance testing 2008 2011 2012 2014 More than 20 years of research and development A visit to Sydney Australia creates excitement and spawns a collaboration for Otometrics. The lateral video head impulse test is proven to have comparable results as scleral search coils. Gold standard vestibular testing in the clinic ICS Impulse is launched proving reliable lateral vHIT data is possible and introducing the new gold standard. Assess all six semicircular canals ICS Impulse is further developed to include the anterior and posterior canals (LARP/RALP), operator feedback, and synchronized room video for the video record/ playback mode. USB Impulse goggle ICS Impulse continues to evolve with a USB goggle along with software enhancements: head position feedback for LARP/RALP, Hex plot, and high resolution vector based graphics. Only video head impulse system approved by Drs Halmagyi and Curthoys More than two decades of testing ICS Impulse® is the first and only HIT system to be approved by Drs. Michael Halmagyi and Ian Curthoys, whose groundbreaking work first brought HIT to the attention of the world in 1988. What is Head Impulse Testing? A side of lesion specific test that identifies which ear is affected in cases of peripheral vestibular loss. Patients with a vestibular loss will exhibit a corrective saccadic eye movement (a “catchup” saccade) either during or after the head impulse. Unsurpassed diagnostic precision in less than 10 minutes In addition to providing an accurate, objective measure of the vestibulo-ocular reflex, the ICS Impulse allows clinicians to test patients with spontaneous nystagmus. Both overt and covert saccades can be detected allowing for proper diagnosis and rehabilitation recommendations. The vestibular function of all six semicircular canals can be assessed and documented in less than 10 minutes from patient entry to reporting. Assess all six Semicircular Canals Head Impulse test is the only test available to assess all six semicircular canals (lateral, anterior, and posterior). I I I I I I Complete your test by assessing lateral, anterior and posterior semicircular canals in less than 10 minutes Head Position feedback precisely tracks motion in free space. Multiple test sessions can be compared using progress graphs and progress data. Assess all six Semicircular Canals and easily view data results. Multiple report options: one-page, multiple test sessions, Hex Plot and large traces. Features and Benefits Ultra-sensitive, High speed USB camera (250 Hz) • Records fast eye movements that allow for identification of overt and covert saccades • More comfortable for the patient with smaller amplitudes of head movement needed Superior Head Motion Sensor for accurate head velocity measurement • Ensures proper position of patient’s head for LARP/RALP testing by precisely tracking motion in free space with superior stability and response time • Provides operator feedback if head impulse was properly performed ensuring correct data analysis Built-in calibration lasers • Calibration is quick and easy, using two lasers incorporated into the goggle • Portable system with no need for additional hardware • Test can be performed anywhere with limited space needed (clinic, emergency room, etc.) Head impulse algorithms based on 20 years of research • Developed by HIT pioneers Drs. Michael Halmagyi and Ian Curthoys • Inaccurate head impulse data is automatically discarded and only accurate data is analyzed • Builds trust that your interpretation and diagnosis are based on accurate data Improved Patient Care The sophisticated camera enables the use of smaller velocity head impulses of only 15 to 20 degrees, and the goggles are the lightest in the industry, making the test more pleasant for the patient. I I I 2-D and 3-D analyses with published normative data. Small and compact for ultimate portability • Easy and efficient for bedside testing and better patient care • Enables accurate testing of acute and immobile patients Record eye and room video synchronously • Utilize ICS Impulse goggles for other vestibular tests • Choose recording and viewing speed allowing you to review data in slow motion for better analysis www.icsimpulse.com - the product www.headimpulse.com - the research Data sharing • Ability to network multiple systems on a shared database • Ability to export data in several formats to share with colleagues or for research purposes I I I
