Ageing effect on air-conducted ocular vestibular evoked myogenic potential
One of the recent diagnostic tests to assess the function of otolithic organs is through vestibular evoked myogenic potential (VEMP) testing. There are equivocal findings on effect of aging on ocular VEMP (oVEMP) parameters with reference to latencies. Hence this study was taken up to investigate the age related changes in oVEMP parameters. This present study considered 30 participants in each age group i.e., young adults, middle-aged adults and older adults. oVEMP were recorded using insert earphone at 100dBnHL at 500hZ short duration tone burst. The results showed in older adult significant difference in response rate, latencies and amplitude as compared to young and middle adult. Hence age should be taken into consideration when interpreting oVEMP results
Measuring Vestibular Evoked Myogenic Potential Using Two Different Procedures.
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
