The study of the age-related change on human postural control by means of the micro-computer.

在与乌普萨拉大学合作的一项调查中，我们利用微型计算机研究了年龄引起的姿势变化，发现身体摇摆随着年龄的增长而增加。然而，老年男性组的波动大于女性组，中年女性组的波动大于女性组。中年男性受试者在下肢施加振动扰动时，其摆动增加幅度最小。它可以安装在DOS-V和PC 98兼容机上。测量了主观视觉垂直线（SVV），它代表与真垂直面的夹角。SVV被认为与耳石功能有关，而耳石功能对姿势控制有重要作用。我们发现，正常人的平均SVV为1.22度，并且该值不随年龄的增长而增加，而梅尼埃病患者在急性期和缓解期或慢性期的SVV都更大。

In an co-operative invostigation with Uppsala University, where age-induced postural change has been studied by means of micro-computer, we could reveal that the body sway increased with advancing age. However, the sway was grater in the male group of the elderly than in the female, and greater in the female group in the middle-aged female. The increase of sway when vibration perturbation was applied to lower extremity was minimum in the male middle-aged group.The program of visual disturbance to the postural control was developed. It could be installed to both DOS-V and PC98 compatible machines. We could show the difference of the visual information in both the image and age.The subjective visual vertical (SVV), which represents the orror angle from true vertical plane, was measured. The SVV has been supposed to have relation to otolith function, which significantly contributes to the postural conttrol. We found that the mean SVV in normal subjects was 1.22 degrees, and that this value did not increase with advancing age, and the SVV was greater in patients with Meniere's disease in both acute phase and remission or chronic phase.
