抄録: This study aimed to compare body sway characteristics of the healthy elderly and the disordered elderly. The subjects were 38 healthy elderly and 24 disordered elderly with disequilibrium. The latter consisted of two groups : 12 elderly with vestibular organ or central nervous systems disorder (central nervous disorders), and 12 elderly with disorder in other systems (other disorders). The measurement device can calculate the center of foot pressure (CFP) of vertical loads from the values of three vertical load sensors, which are located at the corners of an isosceles triangle on a level surface. The data sampling frequency was 20Hz. Four body sway factors with high reliability (unit time sway, frontback sway, left-right sway, and high frequency band power) were used to evaluate body sway. As compared with healthy people, central nervous disorders had larger unit time sway, high frequency band power, and left-right sway factors. Other disorders were larger in unit time sway and high frequency band power factors. Central nervous disorders, as compared with other disorders, had larger unit time sway and left-right sway factors. Disorders produced large and fast sway, and central nervous disorders in particular showed a marked sway in the left-right direction. The existence of disease influenced body sway more than decline in various functions related to posture control with aging, because even with the same elderly, disorders showed a larger body sway.
