Abstract：
BACKGROUND: Functional Movement Screen (FMS) is an important tool in the assessment of exercise practice. Assuming FMS lacks precise validity for assessing postural deficits, further research is needed to assess whether it is a sufficiently precise tool for analysing joint mobility. Research aims were to evaluate: convergent validity of Deep Squat (DS) - one of FMS tests - regarding joint mobility, using data from a three-dimensional motion analysis as a comparable method; DS\'s ability to discriminate between subjects with different joint mobility levels.
METHODS: Sixty subjects were selected (23.6 ± 3.8 years). DS was performed according to FMS guidelines. Subjects\' performance in frontal and sagittal planes was recorded by two video cameras and subsequently scored by two FMS-certified evaluators. Three-dimensional motion analyses of DS were acquired by a Vicon Motion Capture System (200 Hz). Ten trials were acquired for each subject. Ankle, knee, hip, and shoulder angular positions in sagittal plane were determined from the FullBody PlugInGait model. Spearman\'s coefficient examined the correlation between angular positions and DS score. Kruskal-Wallis test was used to assess the DS ability to discriminate between subjects with different joint mobility levels by comparing different scores.
RESULTS: Negligible to moderate correlations were found between DS score and angular positions (-0.5 < r < 0.5). Only shoulder angular positions showed differences between score \"1\" and \"2\" (p < 0.05). Shoulder and hip angular positions showed no differences between score \"2\" and \"3\" (p < 0.05).
CONCLUSIONS: DS yielded low convergent validity regarding joint mobility and did not show the ability to discriminate between subjects with different joint mobility levels.

摘要：
背景：功能性运动屏幕（FMS）是评估运动实践的重要工具。假设FMS缺乏评估姿势缺陷的精确有效性，需要进一步的研究来评估它是否是分析关节活动度的足够精确的工具.研究目的是评估：深蹲（DS）-FMS测试之一-关于关节运动的收敛有效性，使用来自三维运动分析的数据作为可比方法；DS能够区分具有不同关节活动水平的受试者。
方法：选择60名受试者（23.6±3.8岁）。根据FMS指南进行DS。受试者在额面和矢状面的表现由两台摄像机记录，随后由两名FMS认证的评估员评分。DS的三维运动分析通过Vicon运动捕获系统(200Hz)获得。对于每个受试者获得10个试验。脚踝,膝盖,臀部,根据FullBodyPlugInGait模型确定矢状平面中的肩部角度位置。Spearman系数检查了角度位置与DS评分之间的相关性。使用Kruskal-Wallis检验通过比较不同的分数来评估DS区分具有不同关节活动水平的受试者的能力。
结果：在DS评分和角度位置（-0.5结论：DS在关节活动度方面具有较低的收敛效度，并且没有显示出区分具有不同关节活动度水平的受试者的能力。
