Comparison of the Head Impulse Gain of the VOR at Initial Presentation and During Follow-up

Caption

The initial VOR decrement was more profound in those without antibodies than in those with antibodies (median [IQR] = 0.61 [0.46–0.77] vs 0.80 [0.61–1.06], p = 0.048), whereas the VOR decrement was mostly normalized during the follow-up evaluation regardless of the presence of antiganglioside antibodies (median gain difference between initial and follow-up evaluation [IQR] = 0 [−0.08 to 0.03] vs 0.21 [0.06–0.35], F = 4.735, p = 0.034). IQR = interquartile range; VOR = vestibulo-ocular reflex.
