Ocular Vestibular Evoked Myogenic Potentials in Yakshagana Dancers: A Cross-sectional Comparative Study

Background and Aim: The background and aim of this study was to compare ocular vestibular evoked myogenic potential (oVEMP) parameters between Yakshagana dancers and nondancers and evaluate possible vestibulo-ocular adaptations associated with long-term dance training. Methods: Forty adults aged 18–40 years were enrolled and divided into Yakshagana dancers ( n = 20) and nondancers ( n = 20). oVEMPs were recorded using 500 Hz tone burst stimuli. N1 and P1 latencies, peak-to-peak amplitudes, and amplitude asymmetry ratios (AARs) were analyzed. Group comparisons were performed using the Mann–Whitney U -test. Results: Yakshagana dancers demonstrated significantly higher oVEMP amplitudes in both ears compared to nondancers ( P < 0.001). No significant differences were observed in N1 or P1 latencies or AAR between groups ( P > 0.05). Conclusion: Yakshagana dancers demonstrated higher oVEMP amplitudes than nondancers. These findings indicate differences in oVEMP responses between the groups and may reflect vestibular adaptations, differences in gaze-related muscle activation, or a combination of both.
