Aging and Task-specific Training to Reduce Falls

Study Summary

The goal of this clinical trial is to examine the effects of a novel task-specific balance training for reducing environmental falls in community ambulatory older adults who are at-risk of falling. The main questions it aims to answer are: * Does task-specific balance training improve the ability to prevent falling when unexpected perturbations such as slips and trips occur, and/or improve balance control during self-initiated movements? * Does task-specific balance training reduce real-life falls for 18 months after training? Researchers will compare task-specific balance training with conventional balance training and treadmill perturbation-based training to examine how this novel intervention compares to established interventions for improving balance. Participants who participate in the study will be asked to do the following: * Complete a pre-training assessment of their balance control, and then be randomized to one of three training groups: 1) task-specific balance training, 2) treadmill perturbation-based training, and 3) conventional balance training * Complete their assigned training protocol for 8 weeks (2x per week for a total of 16 sessions) * Complete 2 post-training assessments of their balance control, the first being completed immediately after the training is completed, and the second being completed 18 months after the training is completed * Wear a physical activity monitor for 18 months after completing the intervention to monitor their real life falls.

Primary Outcome

Center of mass position will be computed via Helen Hayes marker set using an eight-camera motion capture system and normalized by foot length. The center of mass velocity will be computed by the first order derivative of the center of mass position and normalized to acceleration due to gravity and participant's body height. Reactive stability will be calculated as the shortest perpendicular distance from the center of mass state (position and velocity) to the dynamic feasible theoretical boundar
