RESUMEN
PURPOSE: Masseter vestibular evoked myogenic potentials (mVEMP) involve the connection between the vestibular complex and trigeminal nerve nuclei. Given the theory that migraine is caused by increased activation of the trigeminal nerve, it is believed that mVEMP responses may have influenced in migraine patients. METHOD: The study included 20 individuals with migraine and 20 healthy controls. Latency, amplitude, and interaural amplitude asymmetry ratio of mVEMP responses recorded in migraine patients were compared with control group. RESULTS: Considering the mVEMP normalization study conducted by Basöz et al. (2021) in a similar age group and in the same clinic, latency prolongation and amplitude decrease were observed in subjects with migraines. Migraine is considered a central pathology, as shown in the cervical and ocular VEMP (cVEMP/oVEMP) literature. No difference was observed in the interaural amplitude asymmetry ratio, which is important in peripheral pathologies. Additionally, when the number of pathological ears was examined in order to understand the total exposure, it was observed that the number of pathological ears was significantly higher in the migraine group. CONCLUSION: In future studies, using mVEMP together with cVEMP and oVEMP tests, which allow evaluation of otolith organs and vestibular nuclei, will be valuable in determining the lesion location.

PURPOSE: The Emotional Communication in Hearing Questionnaire (EMO-CHeQ) is designed to evaluate awareness of vocal emotion information and perception of emotion. This study sought to translate the EMO-CHeQ into Turkish in accordance with international standards and to ascertain its validity and reliability statistically by administering it to native Turkish-speaking subjects. METHOD: This empirical study involved collecting data from participants using a scale. A total of 460 individuals, comprising 158 women and 302 men (Mage = 33.43 ± 13.14 years), participated. The data encompassed 295 subjects with normal hearing, 101 hearing aid users, and 64 cochlear implant users. Exploratory factor analysis, followed by confirmatory factor analysis, was employed to ensure construct validity. Internal consistency was assessed with Cronbach's alpha reliability analysis, and content validity was applied to examine how effectively the Turkish version of the scale fulfilled its intended purpose. RESULTS: The total Cronbach's alpha internal consistency coefficient of the scale was .949, and the explained variance was 74.385%. The Turkish version of the EMO-CHeQ demonstrated high construct validity, internal consistency, and explanatory efficacy. The scale revealed significant differences (p < .05) in emotional communication among the normal-hearing group, hearing aid users, and cochlear implant users. CONCLUSIONS: The Turkish adaptation of the EMO-CHeQ is a credible and robust tool for evaluating how individuals perceive emotion in speech. Emotion perception was found to be suboptimal among hearing aid users compared to cochlear implant users, although it was most proficient in those with normal hearing.

RESUMEN
This study utilized cervical vestibular-evoked myogenic potentials tests (cVEMP) and ocular vestibular-evoked myogenic potentials tests (oVEMP) to investigate the vestibulocollic and vestibuloocular reflex arcs and to evaluate cerebellar and brainstem involvement) in essential tremor (ET). Eighteen cases with ET and 16 age- and gender-matched healthy control subjects (HCS) were included in the present study. Otoscopic and neurologic examinations were performed on all participants, and both cervical and ocular VEMP tests were performed. Pathological cVEMP results were increased in the ET group (64.7%) compared to the HCS (41,2%; p > 0.05). The latencies of P1 and N1 waves were shorter in the ET group than in HCS (p = 0.01 and p = 0.001). Pathological oVEMP responses were significantly higher in the ET group (72.2%) compared to the HCS (37.5%; p = 0.01). There was no statistically significant difference in oVEMP N1-P1 latencies between groups (p > 0.05). Because the ET group had high pathological responses to the oVEMP, but not the cVEMP, the upper brainstem pathways may be more affected by ET.
