Abstract
We measured the sitting postural sway of 39 hemiplegic patients under some plane conditions using force plate, then compared their values of three groups among right, left hemiplegic and hemineglect groups.
The result was that right hemiplegic group showed remarkable instability under the plane tilting toward the sound side; however, hemineglect group was unstable under all conditions. The left hemiplegic group had no difference from normal group. Moreover, the plane condition to present greater sway was the sound side in right hemiplegic group, the affected side in both hemineglect and left hemiplegic groups. In short, each group presented greater sway in the left side regardless of their paretic sides.
It was supposed that their trunk laterality since pre-onset had still some influence on those values of postural sway.
