Objective The tested hypothesis states that by manipulating body position, a differentiation in the optimum body position for ocular vestibular-evoked myogenic potential (oVEMP) testing could be obtained. Patients and methods The present study was conducted on 33 ears (33 healthy adult volunteers) with no age or sex limit or any ontological complaint in the audiology unit of Alexandria Main University Hospital. Pure-tone audiometry, tympanometry, and oVEMP testing were performed. Ocular VEMP was performed in four different positions − sitting, supine, right decubitus, and left decubitus positions. Ocular VEMP waveforms were analyzed regarding morphology, latency, amplitude, and threshold. Results (a) oVEMP was present in 90% of the studied cases. (b) The sitting position produced the shortest latencies. (c) The independent position provided the largest amplitude. (d) The dependent position elicited the highest thresholds. Conclusion Although the best position for oVEMP test could not be determined by the present study, the trends found support that the sitting position may be preferred for future oVEMP testing based on the short latencies produced in this position. On the other hand, high thresholds were obtained in the dependent (left decubitus) position, which indicates that it is the least favorable position.
