Vestibular evoked myogenic potentials (VEMPs)‎ with different recording procedures

الملخص EN

Vestibular evoked myogenic potentials (VEMPs) have become an important part of the neuro-otological test battery.

They are recorded from averaged electromyography in response to intense auditory stimuli and are used for the assessment of the otolith function.

VEMPs have been recorded from tonically contracted cervical muscles and this approach is called ‘‘cervical’’ VEMPs (cVEMPs).

They can also be recorded from extra-ocular muscles in response to loud sound and are termed ‘‘ocular’’ VEMPs (oVEMPs).

The combined VEMPs procedure can be substituted for individual oVEMPs and cVEMPs tests.

Objectives : Comparing the results of combined (cVEMPs and oVEMPs) to individual cVEMPs and oVEMPs in healthy subjects.

Method : Individual cVEMPs and oVEMPs then combined (cVEMPs and oVEMPs) are measured and compared with each other in 50 normal healthy adults.

Results : cVEMPs have a detectability of 100 % in both individual and combined modes with comparable latency and amplitude.

While the detectability of oVEMPs was 94 % in both modes of recordings, with no significant difference as regard latencies or amplitudes.
