本研究的目的是确定使用视频分析软件对脑瘫儿童步态视频视觉评估的人际可靠性的影响。两名临床医生观看了同样随机选择的 12 名脑瘫儿童的 20 段矢状面和额面视频记录，这些视频记录是在门诊康复诊所中常规获取的。两名观察者使用观察步态量表对每个下肢的这些视频进行随机序列评分，一次使用标准视频软件，另一次使用视频分析软件（Dartfish (R)），该软件可以执行角度和时间测量。视频分析软件改进了通过加权 Cohen kappa 测量的评分者间一致性，包括总分（kappa 0.778 -> 0.809）以及所有需要角度和/或时间测量的项目（膝盖位置中间站立 kappa 0.344 -> 0.591；后脚位置中间站立 kappa 0.160 -> 0.346；足部接触中间站立kappa 0.700 -> 0.854；脚跟上升时间 kappa 0.769 -> 0.835）。使用视频分析软件是提高视觉视频评估可靠性的有效方法。 (C) 2011 Elsevier B.V. 保留所有权利。
The aim of this study was to determine the effect of using video analysis software on the interrater reliability of visual assessments of gait videos in children with cerebral palsy. Two clinicians viewed the same random selection of 20 sagittal and frontal video recordings of 12 children with cerebral palsy routinely acquired during outpatient rehabilitation clinics. Both observers rated these videos in a random sequence for each lower limb using the Observational Gait Scale, once with standard video software and another with video analysis software (Dartfish (R)) which can perform angle and timing measurements. The video analysis software improved interrater agreement, measured by weighted Cohen's kappas, for the total score (kappa 0.778 -> 0.809) and all of the items that required angle and/or timing measurements (knee position mid-stance kappa 0.344 -> 0.591; hindfoot position mid-stance kappa 0.160 -> 0.346; foot contact mid-stance kappa 0.700 -> 0.854; timing of heel rise kappa 0.769 -> 0.835). The use of video analysis software is an efficient approach to improve the reliability of visual video assessments. (C) 2011 Elsevier B.V. All rights reserved.
