Abstract
We measured sitting postural sway using force plate to investigate plane tilting responses in 10 right and 10 left hemiplegic patients. The results were as follows :
① In right hemiplegic group the body sway tilting toward the unaffected side increased significantly compared with normal group. However, we found no such tendency in left hemiplegic group.
② Right hemiplegic group tended to show greater postual sway tilting toward the unaffected side. On the contrary, left hemiplegic group showed greater postural sway tilting toward the affected side.
③ These discrepancies were thought to be related to the difference caused by the involved side in addition to normal genetic laterality of trunk function.
