Abstract : The skull vibration induced nystagmus test performed with a vibrator applied on vertex and mastoids at frequencies of 30, 60, 100 Hz is a fast, recent, robust bed side examination test which reveals instantaneously a vestibular asymmetry (vibration induced nystagmus or VIN) in dizzy patients and is useful to indicate a lesion side. In clinical practice, results in patients with total unilateral vestibular lesions (TUVL), partial unilateral vestibular lesions (PUVL), brain stem diseases, labyrinthine malformations and results in animal experiments (Curthoys), suggest that bone vibrations applied to vertex or mastoids stimulate all the labyrinthine structures (semi circular canals and otoliths) on both sides at 100 Hz. The vibration induced nystagmus (VIN) is the result of asymmetric responses and is equivalent to a Vestibular Weber Test. In TUVL and PUVL the VIN usually beats toward the intact side and conversely beats toward the lesion side in superior semi-circular canal dehiscences in relation to bone conduction facilitation toward the lesion (third window mechanism). VIN is not modified by vestibular compensation mechanisms and remains permanently as a “vestibular scar”. Since it has been used in occupational medicine as a first level examination test. It is not intrusive and is useful in case of unfeasible caloric test (CT). It addresses vestibular high frequencies and complements HST, HIT and CT which adress middle and low frequencies. It is more sensitive to reveal peripheral than central neurological diseases.
