The proposed research will use an analogous approach to improve balance control. Specifically, we will test whether: 1) the UFOV® computer-based visual-training program or a commercially available video game leads to improved ability to use peripheral vision to monitor changes in the spatial features of the surrounding environment, and 2) whether such changes in visual processing are associated with improved ability to rapidly reach and grasp a handrail for support, in response to a sudden unpredictable balance perturbation. Older adults with documented deficits in UFOV scores will be randomly assigned to either the visual training (UFOV or video game) or a control group. Each training group will undergo two one-hour sessions per week, for five consecutive weeks. Neither group will be given any information as to which training method is expected to be more beneficial.
