Recruiting
Conditions
Vestibular Hypofunction

Other: Conventional rehabilitation program based on Cawthorne Cooksey exercises
Other: Optokinetic Virtual Reality Stimulation
Registration Number
NCT06517446
Lead Sponsor
Istanbul Medipol University Hospital
Brief Summary

The study will be conducted on patients diagnosed with UVH who apply to Prof. Dr. Mete İşeri Ear, Nose and Throat Diseases Polyclinic and Güneşli Erdem Hospital Ear, Nose and Throat and Vestibular Rehabilitation Unit. Participants will be divided into 3 groups by simple randomization (closed envelope) method. To the vestibular rehabilitation group; A conventional rehabilitation program based on structured Cawthorne Cooksey exercises will be applied for 45 minutes once a week with the support of a physiotherapist for 8 weeks. To the optokinetic stimulation group; optokinetic stimulation will be given with virtual reality glasses, and to the combined group; Participants in the vestibular exercise group will receive additional optokinetic stimulation. The application will be done once a week for 8 weeks. Inclusion criteria for the study are; diagnosed with unilateral vestibular hypofunction with VNG test, between the ages of 18-65, class A+ in the System Usability Scale (SUS) and the percentage range being between 96-100%; Exclusion criteria for the study are; Bilateral vestibular hypofunction, visual impairment, neurological disorder and inability to communicate.

Control GroupConventional rehabilitation program based on Cawthorne Cooksey exercisesA 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. Exercises will be done twice a day, 10 repetitions. A home exercise program will be created for patients and they will be asked to do 10 repetitions every day, twice a day. The exercise program will be developed individually, progressively, under the guidance of a vestibular therapist.
Working groupOptokinetic Virtual Reality StimulationIn 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
NameTimeMethod
Headache Impact Scale (HIT-6):8 Weeks

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.

Motion Sickness Severity Scale (MSSS)8 Weeks

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).

Simulator Sickness Survey (SHA)8 Weeks

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".

Secondary Outcome Measures
NameTimeMethod
Fatigue Severity Scale (FSS)8 Weeks

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), retching (5), or vomiting (6).

Dizziness Handicap Inventory (DHI)8 Weeks

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.
