Assessment of sitting balance function for predicting the walking ability in stroke ; a view of anticipatory postural control

这项基础研究的目的是检验从中风后坐位功能恢复状态下的预期姿势控制方面预测行走能力恢复的评估。比较坐位抬起健侧小腿时躯干倾斜角度与体重转移的关系，并与步行和站立功能比较。对于处于慢性维持状态的中风患者，躯干在运动任务中的侧倾角与步行能力和站立功能显著相关。对于恢复状态的卒中患者，活动组躯干在运动任务上的最大倾斜角明显小于非活动组。提示无论恢复程度如何，均能维持预期的坐姿控制，行走和站立功能的恢复受躯干和患肢肌力的影响，与躯干的稳定性有关。

The aim of this basic study was to examine an assessment that predicts the recovery of the walking ability from the aspect of anticipatory posture control in the function recovery state at the sitting level after the stroke. The tilting angle of the trunk associated with the body weight transfer during the motor task lifting the unaffected lower limb on the sitting was compared with the ability of walking and standing function. For the stroke patients of the chronic maintenance state, the tilting angle of trunk sideward on the motor task was correlated significantly to walking ability and standing function. For the stroke patients of the recovery state, the maximum tilting angle of trunk sideward on the motor task was small significantly for ambulatory group compared to unambulatory group. There was suggested that the anticipatory postural control on the sitting was maintained regardless of the recovery level flowing stroke, and the recovery of walking and standing function were influenced by the paralysis and the muscular power of trunk and affected lower limb related to the trunk stability.
