“…Moreover, the variety of protocols to evoke VEMPs including stimulation type and intensity, number of stimuli, testing position for muscle activation, electrode montage and EMG level would definitely resulted in different values (Isaradisaikul et al 2012). Different plateau time used were also found to affect the p13 latency (Marimuthu & Harun 2016). The value from our findings however is still within the range in the standardized norm from the past study.…”

Early identification of any vestibular dysfunction and balance problem in children is crucial for their general well-being. However the identification process, could be challenging and difficult as compared to adults. We conducted a preliminary study to review our initial experience with ocular and cervical vestibular evoked myogenic potentials (oVEMPs and cVEMPs), video head impulse test (vHIT) and Bruininks Oseretsky Test of Motor Proficiency II (BOT-2) on healthy children and also to determine the feasibility of these tests in this population. Twenty one normal healthy children (12 boys and 9 girls), aged between 6 and 15 years old (mean age, 11.15 ± 2.54 years) participated in the study. They underwent oVEMPs and cVEMPs elicited with bone conduction stimulus via minishaker and air conduction stimulus respectively. All six semicircular canals were assessed using the vHIT. Bilateral coordination, balance, running, speed and agility which are the three subsets of BOT-2 gross motor assessment were conducted for balance assessment. All subjects completed the vestibular and balance assessment except for 1 subject who did not complete the vHIT vertical component. The response rate was 100% for oVEMPs, cVEMPs, and BOT-2, and 95.24% for vHIT. The mean latency and mean amplitude for n10

Objective The purpose of the present study was to explore the effect of plateau duration in eliciting masseter vestibular evoked myogenic potentials (mVEMPs) in healthy individuals with hearing sensitivity ≤ 15dBHL. Method A within-subjects design was utilized in the study. Therefore, ipsilateral tone burst evoked mVEMPs were obtained from 30 healthy individuals using the zygomatic montage at 500 Hz tone bursts. Self-monitoring biofeedback was given during the procedure to confirm the tension of the masseter muscle. mVEMPs were recorded across three different plateau duration from 0 to 2 ms with rise/fall time of 2 ms at 95dBnHL. Hence the median and interquartile range were calculated for descriptive analysis of the data followed by non-parametric inferential statistics. Results Tone burst evoked mVEMPs were found to be 100% present across all three plateau durations for both ears at 95 dBnHL. P11 and N21 latencies increased with longer plateau durations in both ears. There were no significant differences in P11-N21 peak-to-peak amplitude or interaural amplitude ratio (IAAR) observed across different plateau durations. IAAR was lowest for a 2 ms plateau duration in the 2–2-2 cycle. No significant variations were found across the three plateau durations. Conclusion Significant differences in P11 and N21 latencies were observed across the three stimulus cycles, while no significant differences were found for P11N21 amplitude and IAAR. Yet, there was found to have the highest amplitude and lowest IAAR for 2–2-2 cycle than 2–0-2 and 2–1-2, suggesting it to be the optimal stimulus among the three of them.
