VEMPs (cVEMPs and oVEMPs) is used to determine the function of the otolith organs in the inner ear, which is responsible for sensing gravity and linear acceleration (such as initiation of movement in a straight line). During testing, electrodes will be places on the patient’s head and neck and the responses will be measured while the patient complete certain movements. The test is quick and easy and although it requires a patient’s response, it can also be done on young children. Results will determine if the otolith organs and nerve connections are intact and functioning optimally.
