背景：在临床实践中，视觉步态观察经常用于确定步态障碍和评估治疗。文献中描述了几项关于观察步态分析的可靠性研究，通常显示出中等可靠性。然而，骨科疾病患者很少受到关注。本研究的目的是确定的可靠性水平的视觉观察步态的患者与骨科disorders.Methods：步态的30例患者提到一个物理治疗师的步态治疗录像。10名评估者，4名有经验的，4名没有经验的和2名专家，通过使用结构化的步态分析表，分别对这些患者的录像步态模式进行了两次评估。信度水平建立通过计算组内相关系数（ICC），使用双向随机设计和基于absolute agreement.Results：有经验的评分者之间的评分者之间的信度（ICC = 0.42; 95%CI：0.38 - 0.46）是可比的，没有经验的评分者（ICC = 0.40; 95%CI：0.36 - 0.44）。专家评分员达到了更高的评分员间可靠性水平（ICC = 0.54; 95% CI：0.48 - 0.60）。经验丰富的评分员的平均评分员内可靠性为0.63（ICC范围为0.57至0.70）。无经验的评分者达到了平均0.57的评分者内可靠性（ICC范围从0.52到0.62）。两个专家评分达到ICC值分别为0.70和0.74.Conclusion：结构化的视觉步态观察使用步态分析的形式，在这项研究中所描述的是适度可靠的。临床经验似乎增加了视觉步态分析的可靠性。
Background: In clinical practice, visual gait observation is often used to determine gait disorders and to evaluate treatment. Several reliability studies on observational gait analysis have been described in the literature and generally showed moderate reliability. However, patients with orthopedic disorders have received little attention. The objective of this study is to determine the reliability levels of visual observation of gait in patients with orthopedic disorders.Methods: The gait of thirty patients referred to a physical therapist for gait treatment was videotaped. Ten raters, 4 experienced, 4 inexperienced and 2 experts, individually evaluated these videotaped gait patterns of the patients twice, by using a structured gait analysis form. Reliability levels were established by calculating the Intraclass Correlation Coefficient (ICC), using a two-way random design and based on absolute agreement.Results: The inter-rater reliability among experienced raters ( ICC = 0.42; 95% CI: 0.38 - 0.46) was comparable to that of the inexperienced raters ( ICC = 0.40; 95% CI: 0.36 - 0.44). The expert raters reached a higher inter-rater reliability level ( ICC = 0.54; 95% CI: 0.48 - 0.60). The average intra-rater reliability of the experienced raters was 0.63 (ICCs ranging from 0.57 to 0.70). The inexperienced raters reached an average intra-rater reliability of 0.57 ( ICCs ranging from 0.52 to 0.62). The two expert raters attained ICC values of 0.70 and 0.74 respectively.Conclusion: Structured visual gait observation by use of a gait analysis form as described in this study was found to be moderately reliable. Clinical experience appears to increase the reliability of visual gait analysis.
