Abstract: Latest developments in technology has equipped the clinician’s ability to evaluate otolithic function through VEMP testing. The present study was taken up to investigate the changes in the VEMP parameters while recording VEMP response with visual feedback system to control EMG. VEMP testing was administered on 20 participants between 20-40 years of age. The study results showed no statistically significant difference in amplitude and latency of cVEMP and oVEMP responses with and without visual feedback system. However, with visual feedback system standard deviations were observed to be reduced for both cVEMP and oVEMP responses. Hence we can conclude that using the visual feedback system to monitor the muscle contraction in otological disorders is easier and more reliable than testing without visual feedback.
