Time-dependent tuning of balance control and aftereffects following optical flow perturbation training in older adults

Prolonged exposure to optical flow perturbations designed to elicit the visual perception of instability during walking in the safety of virtual reality may enforce task-specific, reactive balance control in older adults with potentially favorable aftereffects. This proof of concept study alludes to the potential clinical utility of optical flow perturbations as a training tool to enhance walking balance integrity and/or balance confidence in older adults.
