Fundamentals of Video Head Impulse Test: Lesson 1 – Principles and Mechanics

Please note: exam questions are subject to change.

1. Which of the following findings suggests a vestibular deficit on the right side during a vHIT? VOR gain of 1.0 when head is turned to the right Corrective saccades when the head is turned to the right Absence of nystagmus Smooth pursuit failure on leftward gaze
2. What is a key characteristic of remote camera-based vHIT systems? Use of scleral coils to measure eye movements Use of external cameras and eye-tracking algorithms Integration of infrared goggles with accelerometers Measurement based on electrical eye potentials
3. What is the typical behavior of the eyes in a healthy vestibulo-ocular reflex (VOR) during a head impulse? Eyes move with the direction of the head Eyes move in the opposite direction at equal velocity Eyes show nystagmus during motion Eyes remain fixed regardless of head movement
4. Which of the following is a limitation of head-mounted vHIT systems? Inability to measure covert saccades Need for magnetic calibration Potential for reduced accuracy due to slippage or movement of the device Lack of gain calculation capability
5. In a clinical case, a patient presents with covert saccades during leftward head impulses. What does this most likely indicate? Cerebellar ataxia Normal vestibular function Vestibular hypofunction on the left side Ocular motor nerve palsy
