Functional capacity evaluation (FCE) determines a person's ability to perform work-related tasks and is a major component of the rehabilitation process. The WorkWell Systems (WWS) FCE (formerly known as Isernhagen Work Systems FCE) is currently the most commonly used FCE tool in German rehabilitation centres. Our systematic review investigated the inter-rater, intra-rater and test-retest reliability of the WWS FCE.
We performed a systematic literature search of studies on the reliability of the WWS FCE and extracted item-specific measures of inter-rater, intra-rater and test-retest reliability from the identified studies. Intraclass correlation coefficients ≥ 0.75, percentages of agreement ≥ 80%, and kappa coefficients ≥ 0.60 were categorised as acceptable, otherwise they were considered non-acceptable. The extracted values were summarised for the five performance categories of the WWS FCE, and the results were classified as either consistent or inconsistent.
From 11 identified studies, 150 item-specific reliability measures were extracted. 89% of the extracted inter-rater reliability measures, all of the intra-rater reliability measures and 96% of the test-retest reliability measures of the weight handling and strength tests had an acceptable level of reliability, compared to only 67% of the test-retest reliability measures of the posture/mobility tests and 56% of the test-retest reliability measures of the locomotion tests. Both of the extracted test-retest reliability measures of the balance test were acceptable.
Weight handling and strength tests were found to have consistently acceptable reliability. Further research is needed to explore the reliability of the other tests as inconsistent findings or a lack of data prevented definitive conclusions.
功能能力评估（FCE）可确定一个人执行与工作相关任务的能力，是康复过程的一个主要组成部分。WorkWell系统（WWS）FCE（以前称为伊瑟恩哈根工作系统FCE）目前是德国康复中心最常用的FCE工具。我们的系统评价调查了WWS FCE的评分者间、评分者内和重测信度。
我们对有关WWS FCE信度的研究进行了系统的文献检索，并从已确定的研究中提取了评分者间、评分者内和重测信度的特定项目测量值。组内相关系数≥0.75、一致性百分比≥80%和kappa系数≥0.60被归类为可接受，否则被认为不可接受。对WWS FCE的五个性能类别提取的值进行了汇总，结果分为一致或不一致。
从11项已确定的研究中，提取了150个特定项目的信度测量值。举重和力量测试的评分者间信度测量值中89%、所有评分者内信度测量值以及重测信度测量值的96%具有可接受的信度水平，相比之下，姿势/移动性测试的重测信度测量值中只有67%，运动测试的重测信度测量值中只有56%。平衡测试的两个提取的重测信度测量值均为可接受。
发现举重和力量测试具有始终可接受的信度。由于结果不一致或缺乏数据，无法得出明确结论，因此需要进一步研究以探索其他测试的信度。
