Effectiveness of conventional versus virtual reality-based vestibular rehabilitation exercises in elderly patients with dizziness: a randomized controlled study with 6-month follow-up

Abstract

OBJECTIVES: To investigate the effect of vestibular rehabilitation exercises supported with virtual reality containing real-life environments on dizziness, static and dynamic balance, functional mobility, fear of falling, anxiety, and depression in elderly patients with dizziness. METHODS: In this prospective randomized controlled study, 32-patients aged 65-years and older who applied to the otorhinolaryngology clinic with dizziness complaint randomly assigned to 2 groups. In Group 1 (n=16), vestibular rehabilitation program, supported with virtual reality, and in Group 2 (n=16), conventional vestibular rehabilitation program was applied 30-min a day, 5 sessions per week, 15 sessions in total for 3 weeks. Subjects were evaluated with The Vertigo Symptom Scale (VSS), Dizziness Handicap Inventory (DHI), Berg Balance Test (BBT) and Timed Up & Go Test (TUG), Falls Efficacy Scale-International (FES-I), Postural Stability Test (PST), Geriatric Depression Scale (GDS), Hamilton Anxiety Scale (HAS) at baseline, at the end of the treatment and 6-months after the treatment. RESULTS: Statistically significant improvements were seen in the DHI emotional subscale and TUG in Group 1 compared to Group 2 at the end of the treatment in elderly with dizziness (p<0.05). Also, there were significant improvements in the VSS, all DHI subgroups, and total scores, BBT, HAS in Group 1 compared to Group 2 at the 6-months after the treatment (p<0.05). CONCLUSION: The application of vestibular rehabilitation in a virtual reality environment can lead to additional improvements especially in dizziness symptoms, disability, balance, and mobility in the elderly with chronic dizziness.
