The combined effect of gaze stability and balance exercises using telerehabilitation in individuals with vestibular disorders during the COVID-19 pandemic: A pilot study.

BACKGROUND: Vestibular rehabilitation is recognized as the most effective intervention to relieve symptoms of dizziness and imbalance related to vestibular disorders.

OBJECTIVE: This study aimed to examine the combined effect of gaze stability and balance exercises using telerehabilitation in individuals with vestibular disorders during the COVID-19 pandemic.

METHODS: This pilot study was a quasi-experimental, single-group design pre- to post-telerehabilitation intervention. Individuals with vestibular disorders between the ages of 25-60 participated in this study (n = 10). Participants underwent four weeks of combined gaze stability and balance exercises using telerehabilitation at their homes. The Arabic version of the Activities-Specific Balance Confidence scale (A-ABC), Berg Balance Scale (BBS), and the Arabic version of the Dizziness Handicap Inventory (A-DHI) were assessed pre- and post-vestibular telerehabilitation. Wilcoxon signed rank test was used to examine the magnitude of difference pre- and post-intervention scores of outcome measures. The effect size (r) for the Wilcoxon signed rank was calculated.

RESULTS: After four weeks of vestibular telerehabilitation, there was an improvement in BBS and A-DHI outcome measures (p < .001), with moderate effect size for both scales (r = 0.6). However, A-ABC showed no significant improvement among participants.

CONCLUSION: This pilot study found that the combined effect of gaze stability and balance exercises using telerehabilitation appear to be effective in improving balance and activities of daily living in individuals with vestibular disorders.
