We examined the reproducibility of a kinematic assessment of the sit-to-stand movement in 15 healthy subjects using a standardized protocol. We examined the within-rater and between-rater reliability of the assessment using a clinically feasible method, the video-goniometric measurement method, to analyze the task. Two variables were measured to characterize the sit-to-stand movement: 1) joint angles for four body segments (head, trunk, knee, and ankle) and 2) three events (maximal trunk flexion, lift-off, and maximal trunk extension). High reproducibility was found for all joint angles, except for the head angle. Both within-rater and between-rater goniometric measurements were highly reliable (ICC greater than .80). Identification of the events was reproducible within raters and between different raters. We conclude that this method can lead to reliable assessments of a healthy population. The reliability data established in this study can be used to help clinicians determine the impairments of patients.
我们使用标准化方案，对15名健康受试者从坐起到站立动作的运动学评估的可重复性进行了研究。我们采用临床上可行的视频测角测量方法，来分析该任务，以此检验评估的评分者内和评分者间信度。测量了两个变量来表征从坐起到站立的动作：1）四个身体节段（头部、躯干、膝盖和脚踝）的关节角度，以及2）三个事件（最大躯干前屈、离地和最大躯干伸展）。除头部角度外，所有关节角度均具有高可重复性。评分者内和评分者间的测角测量均具有高度可靠性（组内相关系数大于0.80）。事件的识别在评分者内以及不同评分者之间均可重复。我们得出结论，该方法能够对健康人群进行可靠评估。本研究中建立的信度数据可用于帮助临床医生确定患者的损伤情况。
