Objective: This study is designed to evaluate the effect of ageing on postural sway and limb load asymmetry(LLA) according to visual interception in normal adult. Method: One hundred and seventy three healthy subjects(78 males and 100 females whose age was 50.2 ± 13.8 years-old) volunteered. Subjects was divided into 2 age group whose gender ratio showed relatively even distribution. Old age group include the people whose age is above 60 years. Young age group include the people whose age is below 60 years. Postural sway and body weight distribution were recorded while the subject was standing on two adjacent force platforms(Mediance?; Human-Tech Inc. Korea) during 90s trial. All subjects chose a comfortable stance with feet apart, slightly turned out. and asked to look straight ahead at a fixed point in a quiet room. Results: The result indicate that postural sway and LLA were significantly associated with ageing. In young age group, there is no significant change in postural sway and LLA according to visual interception. In old age group, postural sway is increased significantly during visual interception. Conclusion: Posturl sway and LLA were related with the ageing process. Especially visual ability is important to old people in balance control. And the evaluation of postural sway and LLA will be necessary in old age group for the prevention of fall.

Background : This study is designed to evaluate the effect of ageing on postural sway and limb load asymmetry(LLA) during quiet stance in normal adult. Method : Two hundred and eighty eight healthy subjects(140 males and 148 females whose age was 50.2 ± 13.8 years-old) volunteered. Subjects was divided into 6 age group whose gender ratio showed relatively even distribution. Postural sway and body weight distribution were recorded while the subject was standing on two adjacent force platforms(Medianceⓡ; Human-Tech Inc, Korea) during 120s trial. All subjects chose a comfortable stance with feet apart, slightly turned out, and asked to look straight ahead at a fixed point in a quiet room. Results : The result indicate that postural sway and LLA were significantly associated with ageing. But postural sway and LLA were not associated with each other. Conclusion : Postural sway and LLA were related with the ageing process. And the evaluation of postural sway and LLA will be necessary in old age group for the prevention of fall.
