The feedback box used in the testing of the Vestibular Evoked Myogenic Potential to help subjects maintain the correct level of muscle contarction for the study. For more about this study, visit the Future Studies section.

See below for more pictures concerning VEMP testing.
Electrode placement on the subject to collect data of sternocleidomastoid muscle contraction. An ear-plug is also placed in the ear ipsilateral to muscle contraction to deliver a click-tone which evokes the vestibular system.
A subject placed at -90 degrees on the tilt table during VEMP testing.
The sled attachment to the VALUS is currently used to determine how the VEMP changes in different gravitational fields.
