Ocular and cervical vestibular evoked myogenic potentials produced by air- and bone-conducted stimuli: Comparative properties and effects of age

Utilidad clínica de los potenciales evocados miogénicos vestibulares (VEMPs)

“…La VO aplicada en la mastoides, ofrece oVEMPs de latencias más cortas y con mayor amplitud, pero donde no es posible la comparación con el otro oído [29]. Los oVEMPs decrecen en amplitud a partir de los 50 años [30]. Los oVEMPs por VO sólo se generan en el 50% de las personas mayores de 60 años.…”

Clinical Utility of Ocular Vestibular-Evoked Myogenic Potentials (oVEMPs)

“…The advantages of BC stimulation are that it does not rely on the middle ear for transmission to the vestibule and it produces larger and more reliable oVEMPs. oVEMPs can be recorded in patients of all ages, including the elderly [17] and children [18], but become smaller and less prevalent with increasing age [19][20][21][22][23]. For oVEMPs evoked by BC stimulation, the effects of age are greater for square waves and sine waves [24,17,20,23] compared to tendon hammer taps and low-frequency pulses [20,25].…”

“…Age is a greater problem for oVEMPs evoked by AC sound, as they are generally smaller than those evoked by BC stimulation. The decline with age leads to a high rate of absent responses in older normal subjects [21,22], reducing the clinical utility of the reflex when evoked by AC sound. The false positive rate for BC oVEMPs is much lower, although skull vibration can be variable and does not always produce robust responses.…”

cVEMPs: A systematic review and meta-analysis

“…There seems to be a general consensus in the literature that cVEMP responses can be reliably evoked up until the age of 60. Thereafter, if present, cVEMPs should be interpreted with great care in terms of amplitude and threshold (Welgampola & Colebatch, 2001b;Rosengren et al, 2011;Su et al, 2004). Eleftheriadou and Koudadounarakis (2011) concluded that there is a lack of consensus on procedures for cVEMP recording and interpretation.…”
