Abstract

CONCLUSION:

A pulling sensation in the anteroposterior direction is suggested to originate from a dysfunction of the otolith organs.

OBJECTIVES:

Previous study with vestibular evoked myogenic potential (VEMP) confirmed that a falling sensation (in an up or down direction) and a lateral tilt sensation (in a right or left direction) were caused by otolith lesions. The purpose of this study was to clarify whether a pulling sensation in the anteroposterior (forward or backward) direction originates from otolith dysfunction.

METHODS:

The otolith function was assessed by cervical and ocular VEMPs (cVEMPs and oVEMPs) in 12 patients who complained of a forward or backward pulling sensation. cVEMPs were evaluated by the asymmetry ratio (AR) of the amplitude of the p13-n23 wave and the peak latencies of the p13 and n23 waves. oVEMPs were evaluated by the AR of the amplitude of the n1-p1 wave and the peak latency of the n1 and p1 waves.

RESULTS:

Abnormal ARs on cVEMP were observed in 7 of 12 patients. Nine of 12 patients had abnormal oVEMP results including 3 bilateral absent responses. Most (10 of 12) patients had abnormal cVEMP and/or oVEMP results. The latency of each detected wave was within the normal ranges.
