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.
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
