تأثیر تمرینات تعادلی مبتنی بر واقعیت مجازی بر روی تعادل ایستا، پویا و عملکردی سالمندان

Introduction and purpose: Balance disorder and falling is one of the most important consequences of aging, worrying consequences that entails, including bone fractures .The purpose of this study was to determine the effect of eight weeks virtual reality-based balance training on the balance of elderly men. Materials and Methods: The present study was a semi-experimental and applied to 26 elderly male who were randomly divided into two groups of virtual reality based balance training (13 subjects) and control group (13 subjects) done. In order to evaluate the static, dynamic and functional balance Sharpened Romberg, modified Star Excursion Balance Test (Y) and berg Balance Test were used respectively. The experimental group performed virtual reality-based balance training for 8 weeks, three sessions per week and performed for 45 minutes.   After 8 weeks of training, all stages of the pretest were repeated in the post test. To analyze the data, independent and paired t-test were used at the significance level of 0.05. Finding: The results of independent t-test showed that the implementation of virtual reality-based balance training significantly improved the static balance (t = 1.74, P <0.05), dynamic (t = 2.75, P <0.05) and functional (T = 5.76, P <0.05) in the experimental group compared to the control group. Conclusion: Performing virtual reality-based balance training exercises can greatly improve the balance of the elderly. Therefore, in order to prevent disturbance of balance and falling, it is recommended to use virtual reality based balance exercises in old age.
