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.
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.
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).
DS yielded low convergent validity regarding joint mobility and did not show the ability to discriminate between subjects with different joint mobility levels.
功能性运动测试（FMS）是评估运动实践的重要工具。假设 FMS 在评估姿势缺陷方面缺乏精确的有效性，因此需要进一步研究以评估其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 squat（DS）-FMS 测试之一-与关节活动度的相关性，使用三维运动分析作为可比方法的数据；DS 区分不同关节活动度水平受试者的能力。
选择 60 名受试者（23.6±3.8 岁）。根据 FMS 指南进行 DS。使用两台摄像机记录受试者在额状面和矢状面的运动，并由两名 FMS 认证评估员对其进行评分。使用 Vicon 运动捕捉系统（200Hz）获取 DS 的三维运动分析。为每位受试者采集 10 次试验。从 FullBody PlugInGait 模型中确定矢状面的踝关节、膝关节、髋关节和肩关节角度位置。Spearman 系数检查角度位置与 DS 评分之间的相关性。Kruskal-Wallis 检验用于通过比较不同的评分来评估 DS 区分不同关节活动度水平受试者的能力。
DS 评分与角度位置之间存在微不足道到中度的相关性（-0.5<r<0.5）。只有肩部角度位置在评分“1”和“2”之间存在差异（p<0.05）。评分“2”和“3”之间肩部和髋关节角度位置没有差异（p<0.05）。
DS 与关节活动度的相关性较低，并且没有显示出区分不同关节活动度水平受试者的能力。
