“…Wang et al compared the VEMP responses evoked by click stimuli with those evoked by tone pips in healthy young individuals and observed that the response rates of VEMP were 93 % for click and 100 % for tone pips. 9 In the present study, the initial response at around 13 ms latency was positive wave followed by a negative wave at around 23 ms. This initial response was because of the placement of the electrodes.…”

Background: Vestibular evoked myogenic potentials (VEMP) are electromyographic responses to high-intensity acoustic stimuli to test vestibular system, otolith function and integrity of inferior vestibular nerve. These are easy to perform and non-invasive. In this study, we aimed at clinical application of VEMP to evaluate common peripheral vestibular disorders.Methods: Prospective observational study carried in ENT department during January 2015-November 2016 over 40 patients in age group between 30-70 years with history of vertigo who underwent regular neuro-otological examination and VEMP.Results: Of these, 25 diagnosed with BPPV, 11 with Meniere’s disease, and four with vestibular neuritis. Eight patients showed delayed VEMP responses. 28 (70%) patients had normal VEMP, 12 (30%) had abnormal VEMP responses. Out of 25 patients suffering from benign paroxysmal positional vertigo (BPPV) posterior semi-circular canal was involved in 20 (80%) patients and lateral semi-circular canal in 5 (20%) patients. Abnormal VEMP was found in 5 (20%) patients involving posterior semi-circular canal and in 1 (20%) patient involving lateral semi-circular canal. In patients with Meniere’s disease stage I, Meniere’s disease was observed in 7 (63.6%), stage II in 2 (18.1%), and stage IV disease in 1 (9.09%) patient. In these patients, abnormal VEMP was found in 3 (42.8%) of 7 stage I, 1 (50%) of 2 stage II and 1 (100%) of stage IV patients. One (20%) patient had abnormal VEMP responses during study.Conclusions: VEMP are short-latency EMG that evaluates saccule and inferior vestibular nerve in peripheral vestibular nervous system. VEMP should be considered as complementary test along with conventional vestibular function tests in patients with peripheral vertigo.

“…Compatible with current literature, our study found that the tone burst stimulation resulted in statistically significantly higher P13-N23 amplitudes than other stimulus types. To the best of our knowledge, there is only one study comparing chirp stimulus [9] . Wang and colleagues suggested that chirp stimulus demonstrates shorter latencies and increased speed and reliability.…”

OBJECTIVE: Vestibular evoked myogenic potential (VEMP) is a clinical test used in the diagnosis of vestibular diseases. VEMP uses several stimulants to stimulate the vestibular system and measure myogenic potentials. The aim of this study was to compare the effects of tone burst, click, and chirp stimulation in VEMP on the latency and amplitude of myogenic potentials. MATERIALS and METHODS:We compared the results of 78 ears from 39 volunteers. We measured the sternocleidomastoid muscle potential of each ear following a 500-Hz tone burst, click, and chirp stimulation while in a sitting position and evaluated the latency and amplitude. RESULTS:The tone burst stimulus resulted in waves with longer latency (15.8±1.9 ms) but higher amplitude (35.9±17.1 µV) compared with the other stimuli, and the chirp stimulus resulted in waves with shorter latency (9.9±2.4 ms) but lower amplitude (33±18.6 µV) (p<0.001). The VEMP asymmetry ratio did not significantly differ. CONCLUSION:Because the amplitudes and latencies of different stimuli significantly differ, further studies including more patients and stimulus types are needed to obtain standardized VEMP protocols.

“…The earlier studies have used chirps of different bands-200-10,000Hz by Wang et al (6); 500-4000Hz by Özgür et al (7) and 250-1000Hz by Walther et al (8). All these studies compared the c-VEMP responses of chirp with clicks and 500 Hz tone bursts.…”

“…In 2010, Elberling et al (5) developed octave band chirps to be used to elicit ABRs. After 20 years since c-VEMP was first described, Wang et al (6) compared the c-VEMP responses using Chirps (200-10,000Hz), also called as CE-Chirps, Clicks and tone bursts. Özgür et al (Özgür et al, 2015) used narrowband chirps (500-4000Hz) and compared it with clicks and Tone bursts.…”

The Cervical-Vestibular evoked Myogenic potential(c-VEMP) is a biphasic surface potential recorded from the belly of Sternocleidomastoid muscle (SCM) followed by presenting a short loud sound. Various studies have been done with different stimulus to obtain better VEMP responses. The present study is aimed at comparing the c-VEMP responses (amplitude and latencies) of 500 Hz tone burst with 500Hz octave chirp (360-720Hz). c-VEMP was administered on 60 ears from 30 subjects. After preparation, responses were recorded presenting 500Hz Tone bursts and 500Hz octave chirps. P1-N1 amplitude, P1 and N1 latencies for both stimuli were noted. The chirp was observed to produce significantly larger amplitude and early latencies than tone burst (p<0.01). This study was in search of a stimulus that will produce larger and better response to be used in clinics , Chirp qualifies to be one. Further studies on larger sample size and age groups are required to make generalizations.
