VOR adaptation training and retention in a patient with profound bilateral vestibular hypofunction

A novel training method known as incremental VOR adaptation (IVA) can improve the vestibulo‐ocular reflex (VOR) gain for both active and passive head rotation by coupling active head rotations with a laser‐projected target that moves in the opposite direction of the head at a fraction of the head ve...

Description
Summary:A novel training method known as incremental VOR adaptation (IVA) can improve the vestibulo‐ocular reflex (VOR) gain for both active and passive head rotation by coupling active head rotations with a laser‐projected target that moves in the opposite direction of the head at a fraction of the head velocity. A 51‐year‐old male with bilateral vestibular hypofunction participated in a research protocol using a portable IVA device for 645 days. Passive VOR gains improved 179% to 600%; standing posture and gait also improved. Motor learning within the vestibular system using the IVA method is possible after severe vestibular pathology.
