Effect of vestibular rehabilitation games in patients with persistent postural perceptual dizziness and its relation to anxiety and depression: prospective study.

ABSTRACT

PURPOSE: To evaluate the efficacy of vestibular rehabilitation therapy (VRT) for management of patients with persistent postural perceptual dizziness (PPPD) utilizing subjective and objectives outcome measures and to study the effect of degree of both anxiety and depression in patients on the response of vestibular rehabilitation therapy. METHODS: Thirty-three PPPD patients participated in this study. Selection of patients was based on the diagnostic criteria for PPPD stated by Barany society in the International Classification of Vestibular Disorders (2017). Every patient was subjected to history taking, anxiety and depression assessment, Arabic version of Dizziness Handicap Inventory (DHI), and sensory organization test (SOT). All patients received vestibular rehabilitations therapy. Assessment of VRT outcome was conducted after 6 weeks of VRT. RESULTS: The mean patients' age was 40.9 ± 16.3 years, and nearly equal gender distribution. Vestibular migraine was the most precipitating condition (24.2%) in patients with PPPD. (39.4%) of patients had abnormal scores of anxiety and depression tests, all patients had from moderate to severe degrees of handicap caused by dizziness as measured by DHI, most of patients had abnormal findings in all conditions of SOT. After vestibular rehabilitation therapy, DHI and SOT scores showed significant improvement after VRT. More improvement was found among the group with no anxiety and depression. CONCLUSION: VRT were effective in improving balance abnormalities in patients with PPPD evidenced by subjectively by DHI scores and objectively by SOT results. PPPD patients with concomitant psychiatric disorders; anxiety and depression experienced the least degree of improvement.
