Brief Summary

Bilateral vestibular function is a heterogeneous chronic condition characterized by bilaterally decreased or absent function of vestibular organs, vestibular nerves, or both.1 Patients present with various symptoms such as oscillopsia, imbalance, visual vertigo, cognitive deficits, autonomic symptoms, and impaired spatial orientation. The aim of this study is to investigate the effectiveness of vestibular rehabilitation on balance, dynamic visual acuity and quality of life in patients with bilateral vestibular hypofunction. Twenty patients diagnosed with bilateral vestibular hypofunction by videonystagmography were included in the study. Balance Tests, Visual Analogue Scale, Dynamic Visual Acuity, Dizziness Disability Inventory for quality of life, computer modified for Sensory Interaction in Balance Clinical Test (MCTSIB) tests and Limits of Stability test, which provides evaluation of body movements, which are an important part of balance, in all directions. Evaluations were made at 3 and 6 months before treatment. Physiotherapy sessions were given at two-week intervals. According to the development of the patients, they were asked to perform a home exercise program with 10 repetitions 3 times a day.

Detailed Description

After the initial evaluations, the patients included in the study were included in the rehabilitation program. The rehabilitation program consisted of two phases. The first phase included patient education. All patients were planned to receive a verbal training for 30 minutes by the physiotherapist, including the definition of unilateral vestibular hypofunction, its importance, risk factors, ways of prevention, and recommendations for preventing falls. The second phase consisted of the vestibular exercise program. In this phase, 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. Patients were re-evaluated before the treatment, at the 3rd month and after the 6th month.

Study Groups

vestibular rehabilitation group

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.

Group Type: OTHER

vestibular rehabilitation

Intervention Type: OTHER

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.
