This study investigated whether obstacle crossing performance differs between the first and subsequent attempts in people recovering from stroke. Thirty two people with stroke performed eight trials stepping over a 4 cm high obstacle. Spatiotemporal measures of gait were captured by a Vicon 3D motion analysis system. Data collected only from those subjects who completed three trials leading with the affected limb or three trials leading with the unaffected limb were analysed. These criteria resulted in data from only 22 subjects being used in the analysis. Repeated measures MANOVA analyses showed no differences in the spatiotemporal data between the first, second or third trials when leading with either the affected (p=.317) or unaffected limb (p=.801). In general, intraclass correlations showed there were moderate to strong correlations for the spatiotemporal data across the trials (.612-.952), with the exception of trail step time (.480). These results show there are no differences between the spatiotemporal data collected in the first, second and third obstacle crossing trials. This suggests data from a single trial can be considered representative of performance in people with stroke.
本研究旨在探讨脑卒中患者在康复过程中，第一次和后续尝试跨越障碍物时的表现是否存在差异。32 名脑卒中患者进行了 8 次跨越 4 厘米高障碍物的试验。通过 Vicon 3D 运动分析系统采集步态的时空测量数据。仅分析那些完成 3 次以患侧肢体或 3 次以健侧肢体作为起始腿的试验的受试者的数据。这些标准导致只有 22 名受试者的数据可用于分析。重复测量 MANOVA 分析显示，以患侧（p=.317）或健侧（p=.801）作为起始腿时，第一次、第二次或第三次试验的时空数据无差异。总体而言，除步幅时间（.480）外，跨试验的时空数据的组内相关系数显示出中度至高度相关性（.612-.952）。这些结果表明，第一次、第二次和第三次跨越障碍物试验中采集的时空数据没有差异。这表明单次试验的数据可以代表脑卒中患者的表现。
