Introduction/Background The vestibular evoked myogenic potentials (VEMP) enable evaluate the vestibular system besides the medial vestibulospinal tract, the medial longitudinal fasciculus and the activation of the cervical musculature, so they could be used for the study of different pathologies that affect the mentioned areas. Currently does not exist reference values for Colombian population and that test is not performed routinely. The aim of this study was evaluated a newfangled diagnostic tool and determine the feasibility of its application and possible normal values for Colombian population. Material and method Prospective longitudinal descriptive study preceded by a pilot test in a group of 100 healthy individuals without comorbidities, in which VEMP were performed by auditory stimulation at 97db and recording in sternocleidomastoid muscle during its voluntary activation quantifying latency for P1 and N1 in addition to the amplitude of the potential and differences of latencies P1 and N1 left/right, statistical analysis was performed using SPSS 24. Results The values observed for the electrophysiological variables are correlated with those reported on international literature. The mean for the latency of P1 was 12.54 (SD 1.58), N1 19.49 (SD 2.56), P1 latency difference left/right 0.013 (SD 1.23), N1 latency difference left/right 0.1 (SD 1.91) and the median for amplitude 10.43 (IQR 6.77–15.08). Weak correlation was observed between age and latency of P1 (R = 0.242, P  Conclusion VEMP can be used reliably, safely and consistently using conventional electrodiagnostic equipment that allows auditory evoked potentials recording using a 97-dB click stimulus. Amplitude value is highly variable but there is a correlation between the latency of P1, N1 and age.
