Title

Vestibular contribution to the control of human upright stance

Principal Investigator

Robert Peterka

Study Purpose

The purpose of this study is to better understand how orientation information from the inner ear vestibular motion sensors contributes to balance during stance and to determine the feasibility of a balance prosthesis that activates vestibular sensors using a low amplitude electrical current applied through electrodes placed on the skin behind the ears.

Healthy controls and subjects with confirmed bilateral vestibular loss.

Eligibility Criteria

Participants must be between 18-70 years of age. All subjects should be in generally good health without any history of diabetes, heart disease, stroke, or joint disorders.
