Some people with balance disorders or adverse reactions to antibiotics suffer from bilateral vestibular damage (BVD). They experience difficulty maintaining posture, unstable gait, and oscillopsia. Tyler et al. studied the restitution of postural control through a tactile for vestibular sensory substitution. Because BVD patients cannot integrate visual and tactile cues, they have a lot of difficulty standing. Using a head-mounted accelerometer and a brain-machine interface that employs electrotactile stimulation on the tongue, information about head-body orientation was relayed to the patient so that a new source of data is available to orient themselves and maintain good posture.
