  • Research summary

    The purpose of Cervical Vestibular Evoked Myogenic potential (cVEMP) and Ocular Vestibular Evoked Myogenic potential (oVEMP) tests is to identify any problems originate in these parts of the balance system as this may causes symptoms of dizziness or imbalance. These responses help us understand how our balance system works and identify any abnormalities which will help us in the process of the diagnosis.

    Traditionally, these tests have been performed separately, which takes time and effort for the patient and the clinician. We want to compare this traditional method of testing with a new method of performing both tests simultaneously. The new method will also use a ‘bone vibrator to deliver the sound, rather than a traditional headphone (known as ‘air conduction’). The study aims to identify if there are any advantages to using the new method of testing and determine whether this is a more efficient way of studying our balance system.

    This study will be conducted at the audiology department Great Western Hospital Swindon. 20 participants (40 ears) aged 18-60 years will be recruited from the staff members and local community if needed. Healthy individuals with normal vestibular functions are included.

    Both VEMP tests involve putting wires attached to sticky pads onto the patient’s head and neck. A loud clicking sound is delivered to the patient using a specific device called the ‘B 81 bone vibrator’ and the sticky pads pick us the response from the balance system.

    This research may have positive implications for improving diagnosis and treatment in the future. For example, ‘air conduction’ testing cannot be used if the patient has pathologies of the outer and middle ear. The new method of performing VEMPs may offer an alternative for these individuals.
