Whole Body Vibration In Vestibular Rehabilitation

Study Overview
=================
Brief Summary
-----------------
The aim of this study was to compare the efficacy of home based vestibular rehabilitation program, posturographic biofeedback training and whole body vibration therapy on balance, fall risk, functional mobility, vertigo symptom severity and functions in patients with unilateral vestibular weakness.

Detailed Description
-----------------
A total of 90 patients who were diagnosed as unilateral vestibular weakness were included in this prospective randomized controlled study. They were randomized into three groups each consisting of 30 patients. Home based vestibular rehabilitation program was given to all groups. Fall risk yielded by posturography, Berg balance scale, Timed Up-and-Go test, vertigo visual analogue scale and Dizziness Handicap Inventory were used for comparison.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Placebo Comparator: Home based vestibular rehabilitation program<br>Home-based vestibular rehabilitation program including vestibular adaptation exercises, oculomotor exercises, static and dynamic balance exercises was given to each group in the form of a booklet. All exercises were demonstrated and performed first time at hospital under supervision. Booklet with descriptions and pictures of each exercise were given to patients in order to enable them to perform exercises at home. Vestibular rehabilitation exercises were prescribed as once daily with 10 repetitions at home for one month and wanted to mark a chart if the exercises were performed daily. A diary was used to monitor adherence with the program. | Behavioral: Rehabilitation<br>* Posturography, Whole body vibration<br>|
| Active Comparator: Biofeedback training<br>Biofeedback training was performed five days a week during a month for 20 minutes for a total of 20 sessions with Tetrax ® (Sunlight Medical Ltd) static posture analysis device. Biofeedback training including catch, speedball, sky ball, gotcha exercises which requires following a visual target during weight transfer movements, capturing fast-moving objects by changing the center of gravity or quickly escaping from incoming objects, were applied to the patients in biofeedback training. There is a 30 seconds pause between each exercise. | Behavioral: Rehabilitation<br>* Posturography, Whole body vibration<br>|
| Active Comparator: Whole body vibration<br>Whole body vibration training was also performed five days a week during a month for 20 minutes for a total of 20 sessions with Power Plate Pro 5 (MDD CE 0086). In whole body vibration, single leg, squat and deep squat positions were applied respectively with 35 Hz frequency, including rest periods of 30 seconds between each application. | Behavioral: Rehabilitation<br>* Posturography, Whole body vibration<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| fall risk | fall risk yielded by static posturography | 30 days | 
| Berg balance scale | BBS consists of 14 tasks that are each scored on a scale of 0-4, for a total possible score of 56, indicating no identified balance difficulties. Scoring is on a 5-point ordinal scale with 0 indicating an inability to complete the task and 4 as independent in completing the task. | 30 days | 
| Timed Up-and-Go | TUG is a balance and gait index which requires subjects to rise from an armchair, walk 3 m at a normal and safe pace, turn around, walk back to the chair and sit-down. The time required to complete this task is measured in seconds. | 30 days | 
| vertigo visual analogue scale | A vertically oriented 10 cm line was used for VAS, where no vertigo corresponds to the bottom of the line and the worst vertigo that they could imagine corresponds to the top of the line. Patients were instructed to place a mark on the 10-cm vertical line according to severity of their vertigo. | 30 days | 
| Dizziness Handicap Inventory | The DHI has 25 items, sub-grouped into three domains: functional, emotional, and physical. There are three closed-form answers where patients may check one of the following: yes, sometimes and no with the corresponding scored as 4/2/0. It is possible to use both the total score and the scores of the three subscales separately. | 30 days |
