The aging population is in demand of new tools for better quality of life. Technology has this power. Aim: This study aimed to assess the impact of using Nintendo Wii® in the elderly. Methods: The impact in balance was measured using Berg scale, the activities of daily living using Barthel, cognitive status using MMSe and perceived health status using SF-36. A sample of 65 seniors from a nursing home was randomly allocated to 3 groups: Wii with the supervision of a Physiotherapist (Group A; n=23), Wii without supervision (Group B; n=20), and just Geriatric Gymnastics (Group C; n=22) during 20 sessions. Results: Better attendance and satisfaction were obtained in Group A. In physical terms significant better results were found in SF 36 on Group A and in Berg score of Group C. In mental assessment, a significant worse result was obtained in SF36 of Group A. Also significantly better results in Vitality and Mental Health of Group B were obtained. In therapy exposure, there were significantly better results in group A of the SF36 in individuals with more than 750 minutes (15 sessions). There were no accidents and/or injury registered during the sessions. Conclusion: The supervised use of the Wii, improves the physical component of the elderly and it also can be a motivating factor for exercise practice. This activity can bring better perception of the vitality of the elderly and physical functioning. In other aspects it may also have a depressive effect on some participants. This study highlights the importance of expert supervision when using a Wii as a therapeutic instrument in a senior population.
