目的：本研究的目的是评估在以任务为导向的锻炼计划后，慢性中风患者的平衡和活动能力临床指标的变化是否与生物力学参数的变化平行。设计：10名中风患者参加了一项为期8周的锻炼计划，旨在通过各种功能任务改善平衡和活动能力。在运动干预前后对受试者进行评估。临床测量包括Berg平衡量表和计时起跑，实验室测量包括4个功能任务中的地面反作用力和压力中心位移。结果：完成运动计划后，中风患者的临床测量有显著改善(P<；0.05)。在连续站立和触排大便时的姿势稳定性以及坐立时通过瘫痪的下肢产生的力量也有显著的改善(P<；0.05)。最后一个结果与运动干预后计时起跳的改善有很强的相关性(r=-0.93)。相反，姿势稳定性的增加与Berg平衡量表的改善相关性较差。结论：以任务为导向的锻炼计划可能会改善中风患者的平衡和活动能力的临床和实验室测量。然而，运动干预后临床和实验室指标的变化之间的几个相关性普遍较弱，表明这些结果指标评估了改善的不同组成部分。
Objective: The objective of this study was to evaluate whether after a, task-oriented exercise program, the changes in clinical measures of balance and mobility were paralleled by changes in biomechanical parameters in subjects with chronic stroke.Design: Ten stroke subjects took part in an 8-wk exercise program aimed at improving balance and mobility through various functional tasks. Subjects were evaluated before and after the exercise intervention. Clinical measures included the Berg Balance Scale and the Timed-Up-and-Go and laboratory measures included ground reaction forces and center of pressure displacement during four functional tasks.Results: Stroke subjects showed significant improvements (P < 0.05) in the clinical measures after completing the exercise program. Significant improvements (P < 0.05) were also found in postural steadiness during tandem stance and stool touch and in force production through the paretic lower limb during sit-to-stand. This last result was strongly correlated (r = -0.93) with the improvements on the Timed-Up-and-Go after exercise intervention. In contrast, the increase in postural steadiness was poorly correlated with the improvements on the Berg Balance Scale.Conclusions: A task-oriented exercise program might improve both clinical and laboratory measures of balance and mobility in stroke subjects. However, several correlations between the changes in clinical and laboratory measures after exercise intervention were generally weak, indicating that these outcome measures assessed different components of improvements.
