本研究的目的是确定慢性中风患者的三维运动学和动力学步态特征，并确定这些特征的大小或模式（曲线的形状和方向）是否与步态表现有关（通过自我选择的步态速度测量）。在20例中风患者（年龄：61.2±8.4岁）中，在所有三个平面中发现了不止一种类型的运动学和动力学模式。“快”速度组的人不一定表现出与健康成年人最接近的步态模式。例如，在额平面，典型模式的变化（即，摆动时髋关节外展肌模式）在“快”组中更常见。相关性显示，除了矢状面外，正面和横向轮廓的大小也与速度有关，尤其是正面髋部的力量。结果支持髋外展肌的重要性，除了矢状面肌群，对于瘫瘫和非瘫瘫肢体。此外，与神经系统健康的成年人相似的步态模式并不一定导致慢性中风患者的步态速度更快。(C) 2003 Elsevier B.V.版权所有
The purpose of this study was to identify 3D kinematic and kinetic gait profiles in individuals with chronic stroke and to determine whether the magnitude or pattern (shape and direction of curve) of these profiles relate to gait performance (as measured by self-selected gait speed). More than one type of kinematic and kinetic pattern was identified in all three planes in 20 individuals with stroke (age: 61.2 +/- 8.4 years). Persons in the "fast" speed group did not necessarily exhibit the gait patterns closest to the ones reported for healthy adults. For example, in the frontal plane, a variation from the typical pattern (i.e., a hip abductor pattern in swing) was more common among the "fast" group. Correlations revealed that in addition to the sagittal profiles, the magnitudes of the frontal and transverse profiles are also related to speed, particularly the frontal hip powers. The results support the importance of hip abductors, in addition to the sagittal plane muscle groups, for both the paretic and non-paretic limbs. Furthermore, profiles which resemble gait patterns of neurologically healthy adults do not necessarily result in the faster gait speeds for individuals with chronic stroke. (C) 2003 Elsevier B.V.
