To establish the intrarater and interrater reliability of Wisconsin Gait Scale (WGS) in hemiplegic patients.
Repeated-measures reliability study using video data of stroke patients.
Rehabilitation department of the university hospital.
Nineteen hemiplegic patients with 3-9 months stroke history and two physiatrists and two physical therapists.
Video recordings were assessed twice, at an interval of 2 days, by the two physiatrists and two physical therapists.
Wisconsin Gait Scale.
Internal consistency coefficients for the WGS were excellent; Cronbach scores were 0.91 and 0.94 for the first and third days. Coefficient of Repeatability (CR) for observers' WGS assessments were ranged between 4.23-5.76 and intraclass correlation coefficients for total WGS score were indicated very high interrater reliability at the begining and end, respectively 0.91 and 0.96. Intraclass correlation coefficients for fourteen items of WGS ranged from 0.81 to 1. "Hip hiking at mid-swing", "Circumduction at mid-swing" and "Hip extension of the affected leg" were the items with lowest correlation coefficients. Intrarater reliability for total WGS scores ranged from 0.75 to 0.90.
WGS was found excellent in reliability and may provide an objective means to document the findings from observational gait analysis, which is frequently used in clinical practice by rehabilitation teams.
建立威斯康星步态量表（WGS）在偏瘫患者中的组内和组间信度。
使用脑卒中患者的视频数据进行重复测量可靠性研究。
大学附属医院康复科。
19 例偏瘫患者，病程 3-9 个月，2 名物理治疗师和 2 名物理治疗师。
两名物理治疗师和两名物理治疗师在 2 天的间隔内对视频记录进行了两次评估。
威斯康星步态量表。
WGS 的内部一致性系数很高；第一天和第三天的 Cronbach 分数分别为 0.91 和 0.94。观察者 WGS 评估的可重复性系数（CR）范围为 4.23-5.76，总 WGS 评分的组内相关系数分别在开始和结束时显示出非常高的组间可靠性，分别为 0.91 和 0.96。WGS 的 14 个项目的组内相关系数范围为 0.81 到 1. “摆动中期的髋关节抬高”、“摆动中期的回旋”和“患腿的髋关节伸展”是相关性最低的项目。总 WGS 评分的组内可靠性范围为 0.75 到 0.90。
WGS 的可靠性良好，可提供一种客观的方法来记录康复团队在临床实践中经常使用的观察性步态分析的结果。
