The Landing Error Scoring System (LESS) is a clinical tool often used in research and practice to identify athletes presenting high injury-risk biomechanical patterns during a jump-landing task.
To systematically review the literature addressing the psychometric properties of the LESS.
Three electronic databases (PubMed, Web of Science, and Scopus) were searched on March 28, 2018, using the term "Landing Error Scoring System."
All studies using the LESS as main outcome measure and addressing its reliability, validity against motion capture system, and predictive validity were included. Original English-language studies published in peer-reviewed journals were reviewed. Studies using modified versions of the LESS were excluded.
Systematic literature review.
Level 4.
Study design, population, LESS testing procedures, LESS scores, statistical analysis, and main results were extracted from studies using a standardized template.
Ten studies met inclusion criteria and were appraised using Newcastle-Ottawa Quality Assessment Scale adapted for cross-sectional studies. The overall LESS score demonstrated good-to-excellent intrarater (intraclass correlation coefficient [ICC], 0.82-0.99), interrater (ICC, 0.83-0.92), and intersession reliability (ICC, 0.81). The validity of the overall LESS score against 3-dimensional jump-landing biomechanics was good when individuals were divided into 4 quartiles based on LESS scores. The validity of individual LESS items versus 3-dimensional motion capture data was moderate-to-excellent for most of the items addressing key risk factors for anterior cruciate ligament (ACL) injury. The predictive value of the LESS for ACL and other noncontact lower-extremity injuries remains uncertain based on the current scientific evidence.
The LESS is a reliable screening tool. However, further work is needed to improve the LESS validity against motion capture system and confirm its predictive validity for ACL and other noncontact lower-extremity injuries.
着陆错误评分系统（LESS）是一种常用于研究和实践中的临床工具，用于识别在跳跃着陆任务中表现出高受伤风险生物力学模式的运动员。
系统回顾评估 LESS 的心理测量特性的文献。
2018 年 3 月 28 日，使用术语“着陆错误评分系统”在三个电子数据库（PubMed、Web of Science 和 Scopus）中进行了搜索。
所有使用 LESS 作为主要结果测量指标并解决其与运动捕捉系统的可靠性、有效性和预测有效性的研究均被包括在内。综述了在同行评审期刊上发表的原始英文研究。使用 LESS 修订版的研究被排除在外。
系统文献回顾。
4 级。
使用标准化模板从研究中提取研究设计、人群、LESS 测试程序、LESS 评分、统计分析和主要结果。
有 10 项研究符合纳入标准，并使用适应性用于横断面研究的纽卡斯尔-渥太华质量评估量表进行了评估。总体 LESS 评分显示出良好到优秀的内部一致性（组内相关系数[ICC]，0.82-0.99）、组间一致性（ICC，0.83-0.92）和组间一致性（ICC，0.81）。根据 LESS 评分将个体分为 4 个四分位数时，整体 LESS 评分与 3 维跳跃着陆生物力学的有效性良好。对于大多数涉及前交叉韧带（ACL）损伤关键危险因素的 LESS 项目，个别 LESS 项目与 3 维运动捕捉数据的有效性为中等到优秀。基于当前的科学证据，LESS 对 ACL 和其他非接触性下肢损伤的预测价值仍不确定。
LESS 是一种可靠的筛选工具。然而，需要进一步的工作来提高 LESS 与运动捕捉系统的有效性，并确认其对 ACL 和其他非接触性下肢损伤的预测有效性。
