"This scoping review of 27 diagnostic studies reveals uncertainties in clinical practice regarding the diagnostic accuracy (sensitivity and specificity) of different [head impulse test] HIT methods compared with other vestibular tests or a clinical diagnosis" (p. 551). When comparing any method of HIT to caloric tests for assessing vestibular disorders in patients, the sensitivity (range of 0%-100%; median of 41%) and specificity (range of 56%-100%; median of 94%) was low.
