Correlation between cervical vertigo and vestibular function evaluated by vestibular evoked myogenic potentials

Objective: To analyze the relationship between cervical vertigo and vestibular function evaluated by vestibular evoked myogenic potentials(VEMPs) and analyze the correlations between cervical vertigo and vestibular dysfunction,discuss the related factors of cervical vertigo and guide the clinical treatment of patients with cervical vertigo.Methods: A total of 75 patients with cervical vertigo as the main complaint in the outpatient clinic of the Second Hospital of Shanxi Medical University from August 2019 to July 2020 were set as the diseased group,and 60 patients without cervical and vestibular related diseases in the hospital were selected to set as non-diseased group. The age of diseased group was 12 to 70 years with an average of (46.40±10.91) years,including 25 males and 50 females;and the age of non-diseased group was 22 to 60 years with an average of(43.78±7.75) years,including 19 males and 51 females. VEMPs were performed in the two groups. The data of VEMPs were collected and the results were compared and analyzed. The patients with abnormal cervical myogenic vestibular evoked myogenic potential (cVEMP) were divided into light,moderate and severe groups. The correlation between VEMPs and cervical vertigo and its severity were analyzed by statistical method.Results: (1)The severity of cervical vertigo in diseased group:33 cases of mild,34 cases of moderate,8 cases of severe; cVEMP examination:62 cases were positive and 13 cases were negative,including 13 cases of mild,33 cases of moderate,16 cases of severe. The cVEMP of non-diseased group:4 cases were positive and 56 cases were negative.(2) The level of cVEMP in diseased group was higher than that in non-diseased group (P<0.001). It can be considered that there was a correlation between cervical vertigo and vestibular function.(3)The correlation between the level of cVEMP and the level of cervical vertigo in diseased group was analyzed. The Spearman rank sum test was used,and the correlation coefficient was 0.687,which was statistically significant (P<0.05). And it can be considered that the two indicators have a high degree of correlation.Conclusion: It is feasible to evaluate the relationship between cervical vertigo and vestibular function by VEMPs. For patients with cervical vertigo,the higher the severity,the greater the positive rate of VEMPs,which indicates that it has a greater impact on vestibular function. The treatment of patients with cervical vertigo should be the combination of cervical rehabilitation and vestibular function.
