Introduction: Vestibular Evoked Myogenic Potential (VEMP) is a cervical muscle reflex. Activated by sound stimulation, it is the only study that values the saccule and the inferior section of vestibular nerve functioning, in a selective way. VEMP is used to diagnose: a) inner ear pathology, b) nervous central system diseases. Objective: to determine VEMP parameters in a the population from 18 to 28 years old. Methods: a descriptive study was made. Twenty normal adults between 18 and 28 years old were studied. No significant differences were observed, between the values of absolute latency of the component, where p13 right ear read 12.87 ms with a standard deviation (SD) of 1.78, and left ear read 13.48 ms, SD of 1.69. Conclusions: the presence of the PVME and the analysis of the values of absolute latency of the n23 component, provide integrity to the vestibular pathway. That´s why, they can be diagnosed by peripheral vestibular pathology. It is better to consider differences among the answer of both ears in the same person, at the same time. A significant variable among the subjects was showed by amplitude results. So data should be analyzed carefully. VEMP is useful for the knowledge of vestibular physiology and pathology.
