要約(英語): Stabilometry, which is useful for quantitative evaluation of equilibrium function, is generally performed maintaining Romberg's posture. However, equilibrium function deteriorates with advancing age, and most elderly individuals insist that it may be difficult to maintain the Romberg's posture for several seconds in stabilometry. The aim of this study was to compare the stability in the Romberg's posture with that in a posture in which the heels are together. Stabilograms of the young and the elderly were recorded both with heels together and in the Romberg's posture. The distribution of stabilograms in the 2 postures did not differ significantly, although analysis of stabilogram indices such as area of sway and total locus length suggested that the degree of postural sway with heels together was less than that with Romberg's posture. Therefore, there was no significant difference between the mathematical model of body sway with heels together and that with Romberg's posture.
