Vestibular Rehabilitaion in Bilateral Vestibular Hypofunction

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the etiological factors that constitute bilateral vestibular hypofunction and to investigate the effect of vestibular rehabilitation in these patients. The Caloric test and Video Head Impulse test were applied to evaluate the vestibular hypofunction picture of the patients who applied to Clinic with complaints of vertigo, dizziness and imbalance. Among these patients with BVH, those with vestibular symptoms, imbalance complaints and limited daily living activities were included in rehabilitation. In order to investigate the effectiveness of rehabilitation, oculomotor functions were evaluated using Simulation Of Vestibulo-ocular Reflex Exercises (SVORE) System, balance assessment was done with timed balance tests and quality of life assessment was performed with Dizziness Handicap Inventory.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of Oculomotor Activity (Saccade Frequency Level) | Oculomotor Function Level was evaluated with Simulation Of Vestibulo-ocular Reflex Exercises (SVORE) System. The name of this web-based system that supports VOR wient in the evaluation part of the vestibular software.sth oculomotor and optokinetic stimuli is Simulation of Vestibulo-Ocular Reflex Exercises (SVORE). This system includes Assessment and Rehabilitation departments. The maximum saccade frequency levels were determined with the measurements. For the evaluation of saccade eye movement, patient will be asked to focus on the objects on the screen. | 8 week | 
| Quality of Life Assesment | The level of quality of life was evaluated with Dizziness Handicap inventory.The Dizziness Handicap Inventory (DHI), which evaluates the quality of life in vestibular diseases, was used in the study. This 25-item scale determines the emotional and functional outcomes of patients in vestibular system diseases as well as aggravating factors related to dizziness and impaired balance. | 8 weeks | 
| Static Balance Tests | To evaluate the static balance of the patients; Length of standing in romberg, semitandem, tandem, standing on one leg, eyes open-closed positions were recorded in seconds with a stopwatch. | 8 weeks | 
| Evaluation of Oculomotor Activity (Pursuit Frequency Level) | Oculomotor Function Level was evaluated with Simulation Of Vestibulo-ocular Reflex Exercises (SVORE) System. The name of this web-based system that supports VOR wient in the evaluation part of the vestibular software.sth oculomotor and optokinetic stimuli is Simulation of Vestibulo-Ocular Reflex Exercises (SVORE). This system includes Assessment and Rehabilitation departments. The maximum pursuit frequency levels were determined with the measurements.For the evaluation of pursuit eye movement, patient will be asked to focus continuely on the objects on the screen. | 8 weeks |
