Abstract

[Purpose] This study investigated the initial postural sway characteristics of 30 seconds of one-leg standing. [Subjects] The subjects were 30 healthy adults. [Methods] We measured the locus length per unit area, X-Y unit locus length, and total locus length of 30 seconds of one-leg standing, We performed correlation analysis to compare the 10 one-second segments of the first 10 seconds and the three 10-second segments of the 30 seconds. [Results] There was no correlation of any postural sway value with locus length per unit area in any one-second segment of the first 10 seconds. X-Y unit locus length and total locus length was higher than the other 10-second ? segments in the initial 10 seconds, and was higher than the other 1-sec ? segments in the first second. Locus length per unit area was low in the initial 10 seconds and it was lower than the 8th second in the first 4 seconds. [Conclusion] Our results suggest that the speed and distance of the center of gravity sway increases, but the dependence on deep sensory systems was low. <br>
