A technique for assessing balance that involves applying predictable controlled forces to the hips is described. Impairments in hemiparetic stroke patients' balance were documented by comparing their hip movements during and after a push with those of control subjects of similar age. Stroke patients swayed further and took longer to stabilize hip position than did the control subjects. The disturbance to stroke patients' balance caused by the termination of lateral force caused them more difficulty than did the onset of the force. Differences between stroke patients' involved and noninvolved sides were more pronounced on release from a push than at its onset. The implications of the findings for the assessment and treatment of balance after stroke are discussed.
本文描述了一种通过对髋部施加可预测的控制力来评估平衡的技术。通过比较偏瘫中风患者在推搡过程中和推搡后与年龄相仿的对照受试者的髋部运动，记录了他们平衡能力的损伤情况。中风患者比对照受试者摇摆得更远，且花费更长时间来稳定髋部位置。与侧向力开始作用相比，侧向力终止对中风患者平衡造成的干扰给他们带来了更大的困难。中风患者患侧和未患侧之间的差异在推搡结束时比开始时更为明显。文中还讨论了这些研究结果对中风后平衡评估和治疗的意义。
