Physiologic evidence for improving the magnitude of the lesioned vestibular-ocular reflex (VOR) has existed for decades, yet has only recently been translated to the clinic. Incremental vestibulo-ocular reflex adaptation (IVA) is a safe, noninvasive rehabilitation technique that, after a single 15-min session, can increase the gain of the VOR from 15% to 30% with more adaptation possible with regular use. In addition to improving the gain of the VOR, IVA improves walking velocity, reduces fall risk, and increases the ability to see clearly during head rotation. This paper reviews existing clinical trial data using the IVA method.
