Introduction: The vestibular evoked myogenic potential is a potential of mean latency that measures the muscle response to auditory stimulation. This potential can be generated from the contraction of the sternocleidomastoid muscle and also from the contraction of extraocular muscles in response to high-intensity sounds. This study presents a combined or simultaneous technique of cervical and ocular vestibular evoked myogenic potential in individuals with changes in the vestibular system, for use in otoneurologic diagnosis.
Objective: To characterize the records and analyze the results of combined cervical and ocular VEMP in individuals with vestibular hyporeflexia and in those with Ménière's disease.
Methods: The study included 120 subjects: 30 subjects with vestibular hyporeflexia, 30 with Ménière's disease, and 60 individuals with normal hearing. Data collection was performed by simultaneously recording the cervical and ocular vestibular evoked myogenic potential.
Results: There were differences between the study groups (individuals with vestibular hyporeflexia and individuals with Ménière's disease) and the control group for most of wave parameters in combined cervical and ocular vestibular evoked myogenic potential. For cervical vestibular evoked myogenic potential, it was observed that the prolongation of latency of the P13 and N23 waves was the most frequent finding in the group with vestibular hyporeflexia and in the group with Ménière's disease. For ocular vestibular evoked myogenic potential, prolonged latency of N10 and P15 waves was the most frequent finding in the study groups.
Conclusion: Combined cervical and ocular vestibular evoked myogenic potential presented relevant results for individuals with vestibular hyporeflexia and for those with Ménière's disease. There were differences between the study groups and the control group for most of the wave parameters in combined cervical and ocular vestibular evoked myogenic potential.

This study aimed to compare the effects of cochlear implantation（CI） on vestibular function in patients with large vestibular aqueduct syndrome（LVAS） and in patients with extremely severe deafness with normal inner ear structure. A total of 28 LVAS patients and 28 patients with normal inner ear structure who suffered from extremely severe deafness were selected. The parameters of caloric tests, bone conduction evoked cervical vestibular-evoked myogenic potentials（cVEMP）, bone conduction evoked ocular vestibular-evoked myogenic potentials（oVEMP） and video head impulse tests（v-HIT） were compared between the two groups before and after CI.

Objective: This study compared ocular and cervical vestibular evoked myogenic potentials (oVEMP and cVEMP) among individuals with Parkinson's disease (PD) without dizziness, with nonspecific dizziness (dizziness without orthostatic hypotension), or with dizziness combined with orthostatic hypotension.
Materials And Methods: We prospectively analyzed 30 of each of the three types of individuals who were admitted to Yongchuan Hospital of Chongqing Medical University (Chongqing, China) between June 2022 and April 2023. The three groups received oVEMP and cVEMP measurements using an electromyography-evoked potential system.

Objectives: Cervical vestibular evoked myogenic potentials (cVEMPs) reflect saccular stimulation that results in an inhibitory muscle reflex recorded over the sternocleidomastoid muscle. These responses are utilized to study basic vestibular functions and are also applied clinically. Traditionally, cVEMPs have utilized transient stimuli such as clicks and tonebursts to evoke onset responses.
