To investigate whether a simple observational tool may be a substitute to the time-consuming and costly 3-dimensional (3D) analysis, the study applied the Wisconsin Gait Scale (WGS), enabling assessment which is highly consistent with 3D gait parameters in patients after a stroke. The aim of this study was to determine whether, and to what extent, observational information obtained from WGS-based assessment can be applied to predict results of 3D gait analysis for selected symmetry indicators related to spatiotemporal and kinematic gait parameters. Fifty patients at a chronic stage of recovery post-stroke were enrolled in the study. The spatiotemporal and kinematic gait parameters were measured using a movement analysis system. The symmetry index (SI), was calculated for selected gait parameters. The patients' gait was evaluated by means of the WGS. It was shown that stance % SI, as well as hip and knee flexion-extension range of motion SI can most effectively be substituted by WGS-based estimations (coefficient of determination exceeding 80%). It was shown that information acquired based on the WGS can be used to obtain results comparable to those achieved in 3D assessment for selected SIs of spatiotemporal and kinematic gait parameters. The study confirms that observation of gait using the WGS, which is an ordinal scale, is consistent with the selected aims of 3D assessment. Therefore, the scale can be used as a complementary tool in gait assessment.
为了研究一种简单的观察工具是否可以替代耗时且昂贵的三维（3D）分析，该研究应用了威斯康星步态量表（WGS），其评估结果与中风后患者的3D步态参数高度一致。本研究的目的是确定从基于WGS的评估中获得的观察信息能否以及在多大程度上可用于预测与时空和运动学步态参数相关的选定对称指标的3D步态分析结果。五十名处于中风后慢性恢复阶段的患者参与了该研究。使用运动分析系统测量时空和运动学步态参数。计算选定步态参数的对称指数（SI）。通过WGS对患者的步态进行评估。结果表明，站立百分比SI以及髋部和膝部屈伸运动范围SI最能有效地由基于WGS的估计值替代（决定系数超过80%）。结果表明，基于WGS获得的信息可用于获得与3D评估中选定的时空和运动学步态参数SI所取得的结果相当的结果。该研究证实，使用作为有序量表的WGS对步态进行观察与3D评估的选定目标是一致的。因此，该量表可作为步态评估的辅助工具。
