Despite the ongoing health problem of repetitive strain injuries, there are few tools currently available for ergonomic applications evaluating cumulative loading that have well-documented evidence of reliability and validity. The purpose of this study was to determine the inter-rater reliability of a posture matching based analysis tool (3DMatch, University of Waterloo) for predicting cumulative and peak spinal loads. A total of 30 food service workers were each videotaped for a 1-h period while performing typical work activities and a single work task was randomly selected from each for analysis by two raters. Inter-rater reliability was determined using intraclass correlation coefficients (ICC) model 2,1 and standard errors of measurement for cumulative and peak spinal and shoulder loading variables across all subjects. Overall, 85.5% of variables had moderate to excellent inter-rater reliability, with ICCs ranging from 0.30-0.99 for all cumulative and peak loading variables. 3DMatch was found to be a reliable ergonomic tool when more than one rater is involved.
尽管重复性劳损这一健康问题持续存在，但目前用于评估累积负荷的人体工程学应用的工具很少有充分记录的可靠性和有效性证据。本研究的目的是确定一种基于姿势匹配的分析工具（3DMatch，滑铁卢大学）在预测累积和峰值脊柱负荷方面的评分者间信度。共有30名食品服务工人在进行典型工作活动时被录像1小时，两名评分者从每个人的录像中随机选择一项工作任务进行分析。使用组内相关系数（ICC）模型2,1和所有受试者累积和峰值脊柱及肩部负荷变量的测量标准误差来确定评分者间信度。总体而言，85.5%的变量具有中度至高度的评分者间信度，所有累积和峰值负荷变量的ICC范围为0.30 - 0.99。当有不止一名评分者参与时，3DMatch被发现是一种可靠的人体工程学工具。
