[Abstract]Objective To study the results of video head impulse test (vHIT) and caloric test in patients with definite vestibular migraine (dVM) and probable vestibular migraine (pVM). Methods A total of 40 patients with dVM and 40 patients with pVM were recruited from the vertigo clinic of Shanghai MCC hospital from January 2018 to July 2021. All subjects completed questionnaire, including patient gender, age,headache category (side,pulsatility,influencing factors), accompanying symptoms (photophobia, fear of sound), pain visual analog scale (VAS), vertigo category and vertigo duration. Two groups of patients were subjected to vHit test and caloric test. The gain value and asymmetry ratio of three pairs of semicircular canal function in vHIT test were collected. The slow phase velocity (SPV), unilateral weakness (UW), directional preference (DP)and fixation inhibition index(FD)of semicircular canal function in caloric test were collected.SPSS 20.0 statistical software was used to analyze the data.Results FI(%):Group dVM:48.35±5.28,Group pVM:15.02±5.80,(P=0.038);UW(%):Group dVM:31.82士2. 70,Group pVM: 31.50土3.27,(P=0.975); DP(%): Group dVM: 17.44士1.92,Group pVM: 27.64士2. 15,(P=0. 264); The asymmetry ratio(%) of horizontal semicircular canal gain of vHIT: Group dVM; 48. 35上5. 2, Group pVM: 15.02士5. 80,(P=0. 045). The asymmetry ratio of anterior semicircular canal gain(%):Group dVM: 9.71土1. 25, Group pVM: 9.64士1. 76,(P=0. 986). The asymmetry ratio(%) of the latter half of the regulatory gain: Group dVM: 10. 06土2. 71, Group pVM: 11.71士1. 70 (P=0. 579). Conclusion There were differences in semicircular canal asymmetry ratio and fixation inhibition index of horizontal semicircular canal in vHIT and caloric test between dVM and pVM patients.
