Complete Vestibular Testing Package
The VEMP test measures the vestibular evoked myogenic potential generated by a loud stimulus in the ipsilateral ear.

It is used in balance testing to evaluate saccule function and the integrity of the inferior
vestibular nerve. VEMP can be run from a computer containing the Interacoustics VNG
system... This will create a complete vestibular testing package.

Features
VEMP Ratio Calculated Automatically
High Stimulus Levels from 60-100 dB nHl
Separate patient monitor assist in producing correct muscle tonus throughout the test
Automatic tonus based Left/Right scaling

Note: VEMP runs on the ECLIPSE.
