OBJECTIVES To critically appraise, compare and summarize the quality of the measurement properties of the Dartfish software across various populations and motion tasks. DATA SOURCES Systematic electronic searches were performed in PsychInfo, Embase, Medline@ Ovid, CINAHL and Google Scholar databases from January 1999 to January 2020. STUDY SELECTION Prospective measurement studies published in English peer-reviewed journal that reported on at least one psychometric property (reliability, validity, measurement error) using Dartfish were included. Independent reviewer performed searches and identified studies. DATA EXTRACTION We followed the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) 2018 guideline for abstracting and assessing data quality. Independent extraction was performed by two individual authors. The extracted data involved the author, year, study population, setting, sample size, measurement properties, and information on camera positions, analyzed movement variables and the corresponding strategy for addressing perspective error. DATA SYNTHESIS In total, 23 studies were included in this review. Studies were pooled to examine inter-rater reliability estimates for different tasks: (single-leg squat angle, 2 studies, 115 participants, ICC 0.94, 95% CI: 0.62 - 0.99), (single-leg vertical drop jump angle, 2 studies, 94 participants, ICC 0.92, 95% CI: 0.20 - 0.99) and (vertical drop jump angle, 2 studies, 100 participants, ICC 0.88, 95% CI: 0.83 - 0.92). Concurrent validity (2D Dartfish vs 3D Vicon) in 45 healthy/Parkinson patients was established during push and release task, single leg stance and single leg stance with acutely induced dizziness and correlation 0.59 - 0.98 reported. In measurement error, for tracking angles across various movements, an error of about 10° re-test variation was reported in three studies. CONCLUSION Dartfish is a reliable software for assessing a variety of tasks across multiple contexts of assessments. Evidence suggests that the estimates of motion obtained with Dartfish are valid for single plane movements.

二维运动分析系统的测量特性：系统评价和荟萃分析

目标 批判性地评估、比较和总结 Dartfish 软件在各种种群和运动任务中的测量特性的质量。数据来源 1999 年 1 月至 2020 年 1 月，在 PsychInfo、Embase、Medline@Ovid、CINAHL 和 Google Scholar 数据库中进行了系统的电子搜索。 ，有效性，测量误差）使用 Dartfish 包括在内。独立审查员进行了搜索并确定了研究。数据提取 我们遵循基于共识的健康测量仪器选择标准 (COSMIN) 2018 指南，用于提取和评估数据质量。独立提取由两位独立作者进行。提取的数据涉及作者、年份、研究人群、设置、样本大小、测量属性和相机位置信息，分析运动变量以及解决透视误差的相应策略。数据综合 本综述共纳入 23 项研究。汇总研究以检查不同任务的评分者间可靠性估计：（单腿深蹲角度，2 项研究，115 名参与者，ICC 0.94，95% CI：0.62 - 0.99），（单腿垂直下降跳跃角度，2 项研究，94 名参与者，ICC 0.92，95% CI：0.20 - 0.99）和（垂直下降跳跃角度，2 项研究，100 名参与者，ICC 0.88，95% CI：0.83 - 0.92）。在推送和释放任务期间，在 45 名健康/帕金森患者中建立了并发有效性（2D Dartfish 与 3D Vicon），单腿站立和单腿站立会引起急性头晕，相关性为 0.59 - 0.98。在测量误差方面，对于跨各种运动的跟踪角度，三项研究报告了大约 10° 的重新测试变化的误差。结论 Dartfish 是一款可靠的软件，用于跨多种评估环境评估各种任务。有证据表明，使用 Dartfish 获得的运动估计值适用于单平面运动。
