The aim of this study was to investigate of the effect of web-based System with oculomotor and optokinetic stimulation on rehabilitation in vestibular hypofunction. In the literature, studies on vestibular rehabilitation in unilateral hypofunction are very limited and there is no study about it.

Vestibular system is one of the sensory systems used for postural control. The function of this system is to maintain balance during head movements and to sense the sense of position in the space.Information from the vestibular system goes to the neural processing center. To achieve or maintain postural control as a result of neural reorganization, balance is achieved by controlling eye movements and muscles.

Basic symptoms in vestibular pathologies are; vertigo and dizziness. Besides these; vestibulo-visual symptoms (oscillopsia, decreased visual acuity, visual tilt, etc.), postural symptoms (feeling of falling, swaying, etc.), and symptoms of motion sickness are. The occurrence of these symptoms varies according to diseases and individual characteristics.

In the treatment of vestibular diseases; there are medical treatment, vestibular rehabilitation, surgical interventions and psychosocial education.Medical treatments; it is often used to suppress or control vestibular symptoms (nausea, etc.). Surgical interventions are the last choice of treatment in patients with severe attacks such as disabling function such as labyrinthectomy or signaling the vestibular nerve. Vestibular Rehabilitation is an exercise based approach to maximize central nervous system compensation for vestibular pathology.

In recent years, the effectiveness of the technologies that have been used in different areas of rehabilitation in vestibular rehabilitation has started to be investigated. In the researches, it is seen that virtual reality is one of the most used technologies. In terms of virtual reality usage, it has cost, size and portability advantages (3). However, in other studies, different systems apart from virtual reality are almost not found among the assistive technologies in vestibular rehabilitation.

In recent years, vestibular rehabilitation methods, adaptation to changing sensory conditions and sensory repetition methods in compensation process have been emphasized to increase adaptation to vestibular losses. However, individual therapeutic programs need to be planned in accordance with clinical symptoms. To this end, there is a need to develop reliable objective and technological feedback techniques to measure the interaction of peripheral senses and central adjustment mechanisms.
