One-third of Americans aged over 65 fall each year. Falls threaten functional independence, decrease quality of life, and financially burden patients and their caregivers. Walking is the most common fall-related activity among older adults. Additionally, older adults experience greater step width variability when walking. Importantly, increased step width variability during walking has been found to be a strong predictor of fall risk and incidence. Therefore, an intervention aimed at reducing increased step width variability may consequently reduce fall risk for older adults, which is critically important for themselves, their caregivers, and the community.
