Virtual reality technology can provide a wide range of sensory stimuli to generate conflicts of varying degrees of complexity in a safe environment. OBJECTIVE: To verify the effect of a virtual realitybased balance rehabilitation program for patients with Meniere's disease. METHOD: This observational clinical study included 44 patients aged between 18 and 60 years diagnosed with Meniere's disease submitted to a controlled randomized therapeutic intervention. The case and control groups took betahistine and followed a diet. Case group subjects underwent 12 rehabilitation sessions with virtual reality stimuli in a balance rehabilitation unit (BRU). Patients were assessed based on DHI scores, the dizziness visual analogue scale, and underwent posturography with virtual reality before and after the intervention. RESULTS: After the intervention, the case group showed significantly lower scores in DHI (p < 0.001) and in the dizziness visual analog scale (p = 0.012), and had significantly greater limit of stability areas (p = 0.016) than controls. CONCLUSION: Virtual reality-based balance rehabilitation effectively improved dizziness, quality of life, and limit of stability of patients with Meniere's disease.
