“…The tone burst mVEMP responses were prolonged in latency and increased amplitude when compared with click-evoked mVEMP responses. 13 The mean values of ipsilateralp11, n21 latency and contralateral p11, n21 latency of tone burst mVEMP were prolonged in the present study when compared with corresponding values of the click mVEMP responses reported by De Natale et al 13 Similarly, the mean EMG normalized peak-to-peak amplitudes of ipsilateral and contralateral tone burst mVEMP responses were higher in tone burst mVEMP responses when compared with click-evoked mVEMP responses as evidenced in ►Table 3. These EMG normalized peak-to-peak amplitudes of tone burst mVEMP were higher even with the lower intensity level of stimulation (125 peSPL) when compared with click-evoked mVEMP 13 at 138 dB peSPL.…”

“…These EMG normalized peak-to-peak amplitudes of tone burst mVEMP were higher even with the lower intensity level of stimulation (125 peSPL) when compared with click-evoked mVEMP 13 at 138 dB peSPL. The amplitude asymmetry ratio of ipsilateral and contralateral responses was similar to the corrected ampli-tude asymmetry ratio of click-evoked responses reported by De Natale et al 13 These observations are similar to the findings in the cervical 15,[23][24][25] and oVEMP 16 that report increased latency and higher amplitude for tone burst stimuli than click stimuli.…”

“…Hence, the comparison was made with click-evoked mVEMP that were extensively studied by Deriu and colleagues. 5,7,8,13,14 As with click mVEMP, tone burst mVEMP shows robust and clear positive peak (p11) responses followed by later variable negative peak (n21) responses. The tone burst mVEMP responses were prolonged in latency and increased amplitude when compared with click-evoked mVEMP responses.…”

“…6,12 mVEMP is a relatively new tool and the normative data are available for only click stimuli. 13,14 However, the literature on cVEMP and oVEMP has shown that they are more robust when elicited by 500 Hz tone bursts than the clicks. [15][16][17][18] Also study on frequency tuning of cVEMP and oVEMP 19 shows that the lowest VEMP threshold is obtained at 500 Hz.…”

Background Masseter vestibular evoked myogenic potential (mVEMP) is a recent tool for the assessment of vestibular and trigeminal pathways. Though a few studies have recorded mVEMP using click stimuli, there are no reports of these potentials using the more conventional VEMP eliciting stimuli, the tone bursts. Purpose The aim of the study is to establish normative values and determine the test–retest reliability of tone burst evoked mVEMP. Research Design The research design type is normative study design. Study Sample Forty-four healthy participants without hearing and vestibular deficits in the age range of 18 to 50 years participated in the study. Data Collection and Analysis All participants underwent mVEMP testing using 500 Hz tone-burst stimuli at 125 dB peSPL. Ten participants underwent second mVEMP testing within 1 month of the initial testing to estimate the test–retest reliability. Results Tone burst mVEMP showed robust responses in all participants. There were no significant ear and sex differences on any mVEMP parameter (p > 0.05); however, males had significantly higher EMG normalized peak-to-peak amplitude than females. Intraclass correlation coefficient (ICC) values of tone burst mVEMP showed excellent test–retest reliability (ICC >0.75) for ipsilateral and contralateral p11 latency, ipsilateral EMG normalized p11-n21 peak to peak amplitude, and amplitude asymmetry ratio. Fair and good test–retest reliability (0.4 < ICC > 0.75) was observed for ipsilateral and contralateral n21 latency, contralateral EMG normalized peak-to-peak amplitude, and amplitude asymmetry ratio. Conclusion Tone burst mVEMP is a robust and reliable test for evaluating the functional integrity of the vestibulomasseteric reflex pathway.

“…Gender was another confounder often found to be not controlled. Although it is acknowledged that VEMPs are not significantly affected by gender (Carnaúba et al 2011;Ochi and Ohashi 2003;Versino et al 2015), a recent work reported earlier peak latencies in women for masseter VEMPs (De Natale et al 2019). Whatever the role of gender, from a methodological point of view the use of suboptimal control groups introduces selection bias.…”

Common pitfalls in vestibular-evoked myogenic potential (VEMP) recording methods have been extensively outlined by several reviews. Conversely, the robustness of research methodology employed for the design and conduct of VEMP studies has never been appraised. To fill this void, we conducted a scoping review to map and evaluate the overall quality of the existing literature on VEMPs in central neurological disorders. Five databases were searched from inception to October 2018 for case-control studies on multiple sclerosis (MS), cerebellar and/or brainstem strokes, Parkinson's disease (PD), migraine, and tumors of the cerebellopontine angle. Study quality was assessed using the Agency for Healthcare Research and Quality criteria (AHRQ). The 11-criteria AHRQ scoring system revealed that PD studies achieved a score of 5/11, migraine and cerebellar and/or brainstem stroke a score of 4/11, MS and tumors of the cerebellopontine angle a score of 3/11. Age was found to be one of the main sources of case-control imbalance: compared with controls, cases were significantly older with a 3.6-yr difference in MS studies, 6 yr in PD, up to 12 yr in stroke and tumors. Regardless of pathological condition, case-control groups were found unmatched also by gender. Post hoc power calculations revealed that 53% of the studies achieved the minimum statistical power of 80%. This scoping review revealed low research quality across the literature on VEMPs in central neurological disorders. Scoping lines are provided on actions to be undertaken in future studies to establish a common methodological platform and enhance the quality of research in this field. NEW & NOTEWORTHY Robust methodology is a prerequisite for any type of research, particularly for observational designs such as those employed in vestibular-evoked myogenic potential (VEMP) research. On these premises, this scoping review provides methodological guidelines to improve validity, accuracy and consistency of clinical outcomes from VEMP studies involving central nervous system disorders. In fact, the high risk for bias that is inherent to poor methodology threatens the validity of the findings of works that are technically sound but methodologically flawed.
