Physical capacity tasks (ie, observer-administered outcome measures that comprise a standardized activity) are useful for assessing functioning in patients with low back pain.
The purpose of this study was to systematically review the level of evidence for the reliability, validity, and responsiveness of physical capacity tasks.
MEDLINE, CINAHL, PsycINFO, Scopus, the Cochrane Library, and relevant reference lists were used as data sources.
Two authors independently selected articles addressing the reliability, validity, and responsiveness of physical capacity tasks, and a third author resolved discrepancies.
One author performed data extraction, and a second author independently checked the data extraction for accuracy. Two authors independently assessed the methodological quality with the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) 4-point checklist, and a third author resolved discrepancies.
Data synthesis was performed by all authors to determine the level of evidence per measurement property per physical capacity task. The 5-repetition sit-to-stand, 5-minute walk, 50-ft (∼15.3-m) walk, Progressive Isoinertial Lifting Evaluation, and Timed "Up & Go" tasks displayed moderate to strong evidence for positive ratings of both reliability and construct validity. The 1-minute stair-climbing, 5-repetition sit-to-stand, shuttle walking, and Timed "Up & Go" tasks showed limited evidence for positive ratings of responsiveness.
The COSMIN 4-point checklist was originally developed for patient-reported outcome measures and not physical capacity tasks.
The 5-repetition sit-to-stand, 50-ft walk, 5-minute walk, Progressive Isoinertial Lifting Evaluation, Timed "Up & Go," and 1-minute stair-climbing tasks are promising tests for the measurement of functioning in patients with chronic low back pain. However, more research on the measurement error and responsiveness of these tasks is needed to be able to fully recommend them as outcome measures in research and clinical practice.
体力任务（即由标准化活动组成的观察者管理的结果测量）可用于评估腰痛患者的功能。
本研究旨在系统地回顾体力任务的可靠性、有效性和反应性的证据水平。
使用 MEDLINE、CINAHL、PsycINFO、Scopus、Cochrane 图书馆和相关参考文献作为数据来源。
两位作者独立选择了关于体力任务可靠性、有效性和反应性的文章，第三位作者解决了差异。
一位作者进行了数据提取，第二位作者独立检查了数据提取的准确性。两位作者独立使用共识基于标准选择健康测量仪器（COSMIN）4 点清单评估了方法学质量，第三位作者解决了差异。
所有作者共同确定了每个体力任务的每个测量属性的证据水平。5 次重复坐站、5 分钟步行、50 英尺（约 15.3 米）步行、渐进等速举重评估和计时“Up & Go”任务显示出可靠性和结构有效性的中等至高强度证据。1 分钟爬楼梯、5 次重复坐站、穿梭行走和计时“Up & Go”任务显示出对反应性的正面评价的有限证据。
COSMIN 4 点清单最初是为患者报告的结果测量而不是体力任务而开发的。
5 次重复坐站、50 英尺步行、5 分钟步行、渐进等速举重评估、计时“Up & Go”和 1 分钟爬楼梯任务是测量慢性腰痛患者功能的有前途的测试。然而，需要更多关于这些任务的测量误差和反应性的研究，才能能够将它们作为研究和临床实践中的结果测量完全推荐。
