Abstract:
Aim: The aim of the present study is to compare the latency shifting in aging by using oVEMP in Indian population within the age range of 20-80yrs.
Method: Sixty participants aged 20-80 were tested for ocular vestibular evoked myogenic potentials (oVEMP) using a VEMP system. Electrodes were placed on the inferior oblique muscles, and auditory stimuli were administered to assess muscle responses. Ocular vestibular evoked myogenic potentials (oVEMP) are diagnostic tests that assess the function of the vestibular system. This test can be conducted using an instrument called a VEMP (vestibular evoked myogenic potential) system. Here's how oVEMP tests are typically performed using a VEMP system: The patient is positioned comfortably in a reclined chair or on an examination table. Surface electrodes are placed on specific muscles, the inferior oblique (IO) muscle for oVEMP. The patient is instructed to relax and keep their head still during the test. In positioning for VEMP tests, the highest response rates were achieved when subjects were in a sitting position for oVEMP.
Results: This study shows that normal individuals of age over 60 have the latencies of oVEMP (n10 and p15) are longer than in younger adults.
Conclusion: It was concluded that in individuals of age over 60 have oVEMP (n10 and p15) are longer than in young adults, indicating age-related vestibular changes. These tests, using a VEMP system, assess muscle responses from IO muscles, aiding in vestibular function evaluation and disorder detection.DOI: 10.22271/27103846.2026.v7.i1a.98
