Neuro\u2010otological testing, including a video head impulse test (vHIT) of all semicircular canals (SCs), and gadolinium\u2010enhanced inner ear magnetic resonance imaging were performed.

Canal paresis (CP) was assessed using the vHIT and the caloric test, and results were not significant when vHIT responses were assessed as CP only using the horizontal SC. The difference in the vestibular EH between the presence and absence of CP was not significant if assessed using the vHIT (<jats:italic>P<\/jats:italic>\u2009=\u2009.5591), but it was statistically different if assessed using the caloric test (<jats:italic>P<\/jats:italic>\u2009=\u2009.0467).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The contradictory reaction of VOR in MD patients may result from the high specificity but low sensitivity of CP in the horizontal vHIT.
