对20例亚急性期脑卒中偏瘫患者的时间-距离和矢状面运动步态参数进行了评估。一个测试-重测设计，其中患者进行了测试，在2小时内的两个会话。每届会议包括三个连续的审判。时间-距离参数的组内相关系数（ICC）范围为0.82至0.99。骨盆、髋关节、膝关节和踝关节运动波形的会话内和会话间重复性较高：多重相关系数（CMC）的平均值范围为0.85至0.95。时间-距离参数的会话内变异系数（CV%）范围为3.9 - 14.1，而会话间CV%范围为6.1 - 17.2，显示相似但更高的变异性。偏瘫下肢矢状面运动学的疗程内和疗程间CV%为3.6 ~ 32.4。结果表明，用Vicon 370步态分析系统测量的偏瘫下肢矢状面步态运动学和时距参数具有良好的重复性，可用于评价脑卒中后的治疗效果。(c)2007 Elsevier B.

The within-and between-session repeatability of time-distance and sagittal plane kinematic gait parameters were evaluated in 20 hemiparetic patients with sub-acute stroke. A test-retest design was used in which the patients were tested during two sessions within a 2 h period. Each session comprised three consecutive trials. The intraclass correlation coefficients (ICCs) for time-distance parameters ranged from 0.82 to 0.99. The within- and between-session repeatability of pelvis, hip, knee and ankle kinematic waveforms were high: the mean coefficient of multiple correlations (CMCs) ranged from 0.85 to 0.95. The within-session coefficient of variation (CV%) for time-distance parameters ranged from 3.9 to 14.1, whereas, between-session CV% ranged from 6.1 to 17.2, showing similar but higher variability. The within- and between-session CV% for sagittal plane kinematics of the paretic lower limb ranged from 3.6 to 32.4.The results indicate that time-distance parameters and sagittal plane gait kinematics of the paretic lower limb, measured by the Vicon 370 gait analysis system, are repeatable and can be used to assess treatment effects after stroke.
