Bhatt T, Espy D, Yang F, Pai Y-C. Dynamic gait THE RISING SUSCEPTIBILITY to falling with aging1 stability, clinical correlates, and prognosis of falls among commu- poses a significant health threat to the older adult popula- nity-dwelling older adults. Arch Phys Med Rehabil 2011;92: tion. Slips are responsible for about 40% of outdoor falls 799-805. among community-living adults 70 years of age or older.2 Fall-related injuries are the leading cause of injury-related Objective: To establish an accurate measure for prognostic hospitalization; thus, they exact a great cost, both to the indi- assessment of fall risk in community-dwelling older adults, this viduals and to the health care system.3 It must be noted that study examined the prediction accuracy of a dynamic gait even the healthiest older adults are not immune to devastating stability measure and common clinical tests for slip-related falls.4 A more active lifestyle may inadvertently predispose falls among these adults. them to a greater likelihood of encountering environmental Design: Participants were tested for their fall-risk likelihood perturbatio
