Dizziness is one of the most common complaints in the general population. The caloric
test has long been considered the gold standard for identifying peripheral vestibular
deficits in the differential diagnosis of dizziness. In 1988, the head impulse test
was reported as a test to detect peripheral vestibular deficits [
[1]
]. With the help of high-speed video recording and quantitative head velocity measurement,
the head impulse test with video assistance (video head impulse test; vHIT) is now
becoming a new gold standard for estimating peripheral vestibular function. Especially
in the emergency room, the vHIT may have a greater impact on dizziness diagnosis than
the caloric test because it is simpler and non-invasive: a head thrust test with goggles.
During vHIT, the strap attaching the goggle to the head should be as tight as possible
because goggle slippage may lead to inaccurate measurement [
[2]
]. However, we found that strap tightness also affects the results of vHIT.Keywords
