Title: Wii-Fit For Balance And Gait In Elderly Veterans
Brief Summary: Falls are a major public health problem. They are the leading cause of injuries and injury-related deaths in those aged over 65 years. Balance and gait abnormalities are major reasons for falls in elderly. Exercise interventions improve gait and balance in the elderly. Despite the many proven benefits of exercise, many older adults in the US remain sedentary. This study targets at improving balance and gait with use of Wii-Fit as an exercise program.
