Altered lower limb movement patterns during weight-bearing activities have been described as risk factors for several injuries. The lateral step-down test (LSD) was developed to be a simple, clinician-friendly tool to facilitate the assessment of lower extremity quality of movement during a functional activity. However, there is still conflicting information across the literature regarding how the LSD should be performed.
To critically review the literature regarding the assessment of quality of movement using the LSD and to provide an overview of how this test has been used, describing confounding factors and factors associated with altered movement patterns.
A literature review was conducted in PubMed/MEDLINE, COCHRANE, PEDro, SciELO and LILACS databases, by two independent reviewers.
Sixteen articles met the inclusion criteria. One was a prospective cohort study to identify risk factors for injuries in military recruits. The fifteen remaining were cross-sectional studies involving healthy military recruits, physically active individuals, athletes and/or sedentary subjects, as well as participants with knee and ankle disorders. Worst quality of movement during the LSD has been associated with deficits in hip external rotation and knee extension strength as well as in ankle dorsiflexion range of motion. The reliability of the LSD has been reported to be moderate (κ = 0.59-0.81).
The LSD has adequate reliability and is a simple tool that can be used to quantify lower extremity quality of movement. Future studies should include standardized methods for application, scoring and interpretation of the test, so that confounding factors can be minimized.
负重活动期间下肢运动模式改变已被描述为多种损伤的危险因素。外侧台阶试验（LSD）被开发为一种简单、对临床医生友好的工具，以促进在功能活动期间评估下肢运动质量。然而，关于LSD应如何进行，文献中仍存在相互矛盾的信息。
批判性地回顾关于使用LSD评估运动质量的文献，并概述该测试的使用方式，描述混杂因素以及与运动模式改变相关的因素。
由两名独立审稿人在PubMed/MEDLINE、COCHRANE、PEDro、SciELO和LILACS数据库中进行文献综述。
16篇文章符合纳入标准。一篇是前瞻性队列研究，旨在确定新兵受伤的危险因素。其余15篇是横断面研究，涉及健康新兵、体育活动者、运动员和/或久坐不动的受试者，以及患有膝关节和踝关节疾病的参与者。LSD期间最差的运动质量与髋关节外旋和膝关节伸展力量以及踝关节背屈活动范围的缺陷有关。据报道，LSD的可靠性为中等（κ = 0.59 - 0.81）。
LSD具有足够的可靠性，是一种可用于量化下肢运动质量的简单工具。未来的研究应包括该测试应用、评分和解释的标准化方法，以便将混杂因素降至最低。
