Objective: To investigate the characteristics and clinical utility of vestibular autorotation test (VAT) in patients with vestibular migraine(VM). Methods: This study included two groups, a VM group (441 patients from Tianjin First Center Hospital between January 2015 and May 2016) and a control group (65 healthy subjects). Both groups undertook VAT; the parameters evaluated were horizontal gain/phase, vertical gain/phase and asymmetry. The differences in VAT results between the two groups were investigated. Results: There were statistically significant differences in VAT results between the VM and the control group, namely elevated horizontal gain at frequency 2, 3, 4 and 5 Hz, delay horizontal phase at frequency 2, 4, 5 and 6 Hz, elevated vertical gain at frequency 2-6 Hz and delay vertical phase at frequency 4-6 Hz. There was no significant difference in asymmetric values between the VM group and the control group. Conclusions The results of this study indicate that VM patients have elevated horizontal gain and vertical gain, and delay horizontal phase and vertical phase. It is suggested that VAT represents a useful diagnostic tool which may provide objective evidence for the diagnosis and differential diagnosis of VM.
