ABSTRACT

The brain is capable of major reorganization even many years after an injury, with appropriate rehabilitation. The highly plastic brain responds best when the therapy is motivating and has a benefit that is recognized by the patient. The major objective of this study was to estimate feasibility and efficacy of an electro-tactile vestibular substitution system (ETVSS) in aiding recovery of posture control in patients with bilateral vestibular loss (BVL) during sitting and standing. Subjects used the BrainPort balance device for a period from 3 to 5 days. Subjects readily perceived both position and motion of a small ‘target’ stimulus on the tongue display, and interpreted this information to make corrective postural adjustments, causing the target stimulus to become centred.
