METHOD FOR TESTING FUNCTION OF OTOLITH ORGAN

摘要

PROBLEM TO BE SOLVED: To provide a simple and inexpensive method for testing a function of an otolith organ, which has safety.;SOLUTION: A head inclination sense Y, which is a difference between a head inclination angle X and a subjective ocular vertical position A, is calculated. A straight line is determined by plotting data in such a manner that the head inclination angle X is set as a coordinate of a lateral axis and that the head inclination sense Y is set as a coordinate of a longitudinal axis, and an inclination of the straight line is defined as a head inclination sense gain Z. When the head inclination sense gain Z is 1.20 or more or 0.90 or less, it is determined that a subject's otolith organ has an anomaly.;COPYRIGHT: (C)2015,JPO&INPIT
