I. Introduction
Annually, an estimated 36 million falls occur among older adults 65 years of age and older, affecting 1 in every 4 adults. Of those affected, 8 million are injured and an estimated 3 million adults sustain injuries that require emergency care. [1] Falls may also lead to fatality; on average, 32,000 deaths a year are attributed to falls in the United States alone, and worldwide falls are the second leading cause of unintentional death. [1], [2] Furthermore, the incidence of fatal falls continues to grow as the United States saw a 30% increase in fall-related deaths for older adults between 2009 and 2018. [3] In the coming years, these numbers are expected grow, as the number of Americans 65 and older, thus at high risk of falling, will continue to increase. Economic costs associated with falls in older adults amount to $50 billion for non-fatal fall-related injuries and $754 million in fall-related fatalities. Without intervention, it can expected that these costs will grow as an increasing amount of adults reach older ages and become at higher risk for falls. Thus, early detection of adults at higher risk for falls would be beneficial for earlier interventions aimed at maintaining functional capacity across the lifespan and minimizing the risk of injurious falls.
