摘要：Background:It has been reported that factors such as age and vestibular pathology(i.e.vestibular migraine)could impact self-motion perception during vestibular stimulation.However,to our knowledge,no objective test has been developed to quantify self-motion perception during clinical vestibular evaluation.Objective:The main objective of the present study was to quantify vestibular perception during caloric vestibular stimulation using a tachometer.Methods:Twenty-two participants were divided into three groups:1)younger healthy adults,2)older healthy adults and 3)vestibular impaired adults.All participants performed bithermal water caloric irrigation during which slow-phase eye velocity(SPV)was measured using videonystagmography and self-motion velocity perception was assessed using a handheld tachometer(RPM).Results:The results revealed a significant difference in SPV between vestibular impaired ears and both healthy groups,and a significant difference in self-motion velocity perception between healthy young and vestibular impaired participants.Conclusions:This study suggest that the SPV similarly to self-motion perception(RPM)can differentiate between vestibular impaired and young healthy participants.Future work is required to assess the influence of self-motion perception in aging.
