It can also be used to obtain objective threshold information.
Electro-Cochleography, ECOG, is mainly indicated to confirm endolymphatic hydrops and Meniere’s disease.
Vestibular Evoked Myogenic Potentials (VEMP) is mainly indicated to support diagnose superior canal dehiscence a syndrome, Meniere’s disease, vestibular neuritis,
otosclerosis as well as central disorders such as Multiple Sclerosis.
Vestibular Auto-rotation Test/ Active Head Rotation Test “VAT/AHR” are tests essentially to determine the integrity of mid and high frequency vestibular functions.
