Abstract

Background: A minimal number of studies have documented the impact of Vestibular rehabilitation (VR) on the recovery rate of patients with bilateral vestibular hypofunction (BVH).

Objective: The purpose of this study was to investigate the effectiveness of structured VR programs on severity of dizziness, kinesiophobia, balance, fatigue, quality of sleep, activities of daily living (ADL) and quality of life (QoL) in subjects with chronic BVH.

Method: Twenty-five participants diagnosed with BVH were included in the study. A structured VR program was applied in 50-minute sessions once a week and as a home exercise program 3 times a day over 8 weeks. Participants were evaluated for severity of dizziness with the visual analog scale, for kinesiophobia with the tampa scale of kinesiophobia, for balance with the Semitandem, tandem, and standing tests, for quality of sleep with the Pittsburgh sleep quality index, for ADL with the vestibular disorders activities of daily life, for QoL with dizziness handicap inventory and for fatigue with the fatigue severity scale at the baseline (T1), at 4th week (T2), 8th week (T3), and 20th week (T4) after study started.

Results: Significant difference in terms of Tandem Test and 1 Leg Stand Test was found in favor of T3-T4 Period (P < .05). There were significant improvements in terms of vestibular disorders activities of daily life, tampa scale of kinesiophobia, Pittsburgh sleep quality index and dizziness handicap inventory in favor of the T3 to T4 Period (P < .05). Significant difference in terms of visual analog scale was found in favor of T2 Period (P < .05).

Conclusions: A twelve-week structured VR program may enhance severity of dizziness, kinesiophobia, balance, quality of sleep, ADL and QoL in participants with chronic BVH.
