这项研究的目的是确定录像观察步态分析(VOGA)评估的评定者之间的可靠性。54名有执照的物理治疗师担任评分员，他们的临床经验各不相同。三名表现出异常步态模式的类风湿性关节炎患者作为录像带的对象。评分员分析了每个患者在站立的四个子阶段中受累最严重的膝盖，以了解膝关节屈曲和膝外翻的运动学变量。评分员被要求确定这些变量是否不足、正常或过度。在整个步态周期中分析的时间空间变量是节奏、步长、步长、站立时间和步幅。广义卡帕系数在0.11到0.52之间。组内相关系数(2，1)和(3，1)略高。我们的结果表明，物理治疗师的VOGA评估只有轻微到中等的可靠性，需要提高使用这一技术的物理治疗师评估的评委间可靠性。我们的数据表明，步态分析训练需要更大程度的标准化。
The purpose of this study was to determine the interrater reliability of videotaped observational gait-analysis (VOGA) assessments. Fifty-four licensed physical therapists with varying amounts of clinical experience served as raters. Three patients with rheumatoid arthritis who demonstrated an abnormal gait pattern served as subjects for the videotape. The raters analyzed each patient's most severely involved knee during the four subphases of stance for the kinematic variables of knee flexion and genu valgum. Raters were asked to determine whether these variables were inadequate, normal, or excessive. The temporospatial variables analyzed throughout the entire gait cycle were cadence, step length, stride length, stance time, and step width. Generalized kappa coefficients ranged from .11 to .52. Intraclass correlation coefficients (2,1) and (3,1) were slightly higher. Our results indicate that physical therapists' VOGA assessments are only slightly to moderately reliable and that improved interrater reliability of the assessments of physical therapists utilizing this technique is needed. Our data suggest that there is a need for greater standardization of gait-analysis training.
