Introduction

The head impulse test (HIT) was first described as a clinical bedside test in 1988 [1] and since then has become the main bedside test for the evaluation of function of the vestibulo-ocular reflex (VOR). For many years, the HIT was evaluated clinically, and was largely based on the examiner’s ability to correctly perform the test and to detect catch-up saccades.

In recent years, smartphone technology has led to the development of smaller cameras with higher spatial and temporal resolution, also allowing eye tracking with video-oculography (VOG) to expand to VOG-assisted HIT recordings, leading to the video HIT (vHIT) [2, 3, 4]. The vHIT has evolved in the last years into a valuable and widely used diagnostic tool for evaluating dizzy patients, by helping quantify the VOR gain [5] and being superior to the bedside HIT [6]. Commercially available devices include the ICS Impulse™ and the EyeSeeCamHIT™.

Although often used there are still some methodological questions to be...
