Summary:
Study, Prof. Dr. It will be performed on patients diagnosed with UVH who apply to Mete İşeri Ear Nose and Throat Diseases Clinic and Güneşli Erdem Hospital Ear Nose Throat and Vestibular Rehabilitation Unit. Participants were selected by simple randomization (sealed envelope) method; will be divided into two groups: control group and study group. Criteria for inclusion in the study; While he was diagnosed with unilateral vestibular hypofunction with the VNG test, was between the ages of 18-65, was in the A+ class in the System Usability Scale (SCS), and had a percentage range between 96-100; Exclusion criteria of the study; Bilateral vestibular hypofunction, visual impairment, neurological disorder, and inability to communicate. To the control group; A conventional rehabilitation program based on structured Cawthorne Cooksey exercises will be applied for 45 minutes with the support of a physiotherapist, once a week for 8 weeks. As for the working group; In addition to the program of the participants in the vestibular exercise group, optokinetic stimulation will be given through oculus glasses. Application will be made 1 day a week for 8 weeks.

Primary Outcome Measures: Sociodemographic data form, In this form; The patient's age, gender, profession, whether he/she smokes and drinks alcohol, additional diseases, previous surgeries, medications used, history of the disease, onset of the disease, etc. will be questioned., 8 WEEKS|Headache Impact Scale (HIT-6):, Bayliss et al. It is a short questionnaire designed to assess migraine pain from the patient's perspective and track lost time. Each item is answered using a 5-point Likert scale (6=never, 8=rarely, 10=sometimes, 11=very often, 13=always). The final score is determined from the sum of 6 items with a range from 36 to 78. Higher scores indicate greater impact., 8 WEEKS|Fatigue Severity Scale (FSS), It was developed by Krupp in 1989. It is a scale consisting of 9 questions. Each item is scored between 0 and 7. The total score is divided by 9, and if the average is \<4, it is considered as no fatigue, and if the average is ≥4, it is considered as fatigue., 8 WEEKS|Dizziness Handicap Inventory (DHI), It is used to determine the physical, sensory and functional effects of vestibular system pathologies. Questions 1, 4, 8, 11, 13, 17 and 25: Physical disability; Questions 2, 9, 10, 15, 18, 20, 21, 22 and 23 examine emotional disability; Questions 3, 5, 6, 7, 12, 14, 16, 19 and 24: Refers to functional disability. For each question, the answers consist of yes (4 points), no (0 points) and sometimes (2). In scoring the subunits of the inventory, 28 points were accepted as the cut-off value to determine physical disability and 36 points to determine functional and sensory disability. High scores indicate that the patient's complaint of dizziness is severe., 8 WEEKS|Motion Sickness Severity Scale (MSSS), It is a 7-point scale rated from 0 to 6, where participants select the item that best describes their current condition: none (0), stomach awareness or discomfort (1), mild nausea (2), moderate nausea (3), severe nausea (4). ), gagging (5) or vomiting (6)., 8 WEEKS|Simulator Sickness Survey (SHA), It has been widely used to evaluate various forms of disease triggered by virtual environments. 16 symptoms such as eye fatigue, nausea, sweating and headache are evaluated in 4 different severity levels (0: none, 1: mild, 2: moderate and 3: severe). Symptoms are grouped into 3 non-mutually exclusive categories representing nausea, oculomotor disturbance, and disorientation. Higher scores in each category indicate stronger perceptions of underlying disease symptoms. A total score above 20 is considered "poor-failing"., 8 WEEKS
