Vestibular rehabilitation was performed. The following exercises were done with the patients: vestibular adaptation exercises, oculo-motor exercises, standing by changing the support area, the support surface and the arm positions, heel-toe walking, walking with head rotation, backward walking, counting on a soft surface with eyes open and closed, and dynamic balance exercises were taught to the patients. The exercise program was arranged 3 times a day for 6 months, and each exercise was 10 repetitions. The patients were called for physiotherapist control once every 2 weeks.

Vestibular rehabilitation consisted of a total of 12 sessions, rearranged every 15 days. These exercises were prepared gradually to increase the vestibulo-ocular reflex and vestibulospinal reflex. The following exercises were done with the patients: vestibular adaptation exercises, oculo-motor exercises, standing by changing the support area, the support surface and the arm positions, heel-toe walking, walking with head rotation, backward walking, counting on a soft surface with eyes open and closed, and dynamic balance exercises were taught to the patients. The therapist gave the patients a home exercise program. It was emphasized that the exercises should be applied as 10 repetitions. After the session, the exercises shown to the patients were explained in written form and given as home exercises. They were also asked to do home exercises 3 times a day, 10 repetitions, for 15 days. Patients were re-evaluated before the treatment, at the 3rd month and after the 6th month.

With the limits of stability program on the balance device called Otometrics ICS Balance Platform, the body's final reaching points, the speed of movement, and direct control were evaluated, in 8 directions. Within this device, the modified for Sensory Interaction in Balance Clinical Test test was evaluated by showing areas of oscillation. Modified-CTSIB is a clinical test that is generally used as a semi-quantitative test measurement, and is scored according to the person's ability to perform various standing static positions.Before removing the patient on the device, the center of gravity is determined by entering the height and weight, and the patient visually sees the center of gravity when he/she gets on the balance platform. Then all tests are done according to this center of gravity.

Dizziness Handicap Inventory was used to evaluate the quality of life of patients. This scale consists of 25 items that determine the aggravating factors of patients' dizziness and balance disorder, as well as emotional and functional outcomes in vestibular system diseases.

The test was performed using the Snellen visual acuity chart. During the test, the patient was first asked where he read on the eye board on the wall while the head was fixed, and it was recorded. Then, while the patient's head was turned to the right and left rapidly 2 times per second, the patient was asked to continue reading on the eye board, and the answers were recorded.
