Primary Outcome Measures

Name	Time	Method
Sensitivity and specificity of crHIT-vertical	9 months	How many participants are correctly identified as either having a vestibular dysfunction or being healthy controls

Secondary Outcome Measures

Name	Time	Method
Subject discomfort - symptoms	9 months	Number of subjects indicating motion sickness symptoms during the crHIT test. If motion sickness is present subjects are asked to rate the symptoms of motion sickness and severity on scale 1 to 5, where 1 is minimum and 5 is severe.
Subject discomfort - test apparatus	9 months	Subjects rate the comfort of chair, head rest and goggle on scale 1 to 5, where 1 is very uncomfortable and 5 very comfortable.
