Outcomes after vestibular rehabilitation and Wii (R) therapy in patients with chronicunilateral vestibular hypofunction

Introduction and objectives: Vestibular rehabilitation therapy is an exercise-based programme designed to promote central nervous system compensation for inner ear deficit. The objective of the present study was to analyse the differences in the perception of handicap, the risk of falls, and gaze stability in patients diagnosed with chronic unilateral vestibular hypofunction before and after vestibular rehabilitation treatment with complementary Wii (R) therapy. Materials and methods: A review was performed on the clinical histories of patients in the vestibular rehabilitation area of a university hospital between April 2009 and May 2011. The variables studied were the Dizziness Handicap Inventory, the Dynamic Gait Index and dynamic visual acuity. All subjects received complementary Wii (R) therapy. Results: There were 69 cases (41 woman and 28 men), with a median age of 64 years. The initial median Dizziness Handicap Inventory score was 40 points (range 0-84, percentile 25-75 = 20-59) and the final, 24 points (range 0-76, percentile 25-75 = 10.40), 1)p < .0001. The initial median for the Dynamic Gait Index score was 21 points (range 8-24, percentile 25-75 = 17.5-2.3) and the final, 23 (range 12-24, percentile 25-75 = 21-23), P < .0001. The initial median for dynamic visual acuity was 2 (range 0-6, percentile 25 similar to 75 = 1.4) and the final, 1 (range 0-3, percentile 25-75=0-2), P < .0001. Conclusion: A reduction was observed in the Dizziness Handicap Inventory Values. Values for the Dynamic Gait Index increased and dynamic visual acuity improved. All these variations were statistically significant. (C) 2013 Elsevier Espana, S.L.U. and Sociedad Espanola de Otorrinotaringologia y Patologia Cervico-Facial. All rights reserved.
