Description

The speed of lateral body sway during the movements was recorded by the gravicorder (NEC 1G06) from 12 subjects with normal equilirium function, and the following results were obtainded; 1) When the sway action was performed on the horizontal platform of the gravicorder, there was no directional preponderance in sway speed of all subjects. 2) When the platform was tilted to the right or left, all subjects swayed faster to the tilted side. 3) When the subjects stooped as to lower their gravity center, most subjects could sway faster to the both direction. 4) The speed of lateral sway was influenced by the head position. Namely, subjects swayed faster to the side whose head was tilted and slower to the opposit side. Lateral sway was easier when the head was tilted forward than when it was tilted backward. On the other hand, subjects felt most difficulty in swaying to the opposit direction when they twisted their head. 5) When the subject knew the direction of sway in advance, they could sway dominantly faster.
