The Functional Movement Screen (FMS) assesses the quality of movements, including the deep squat (DS), which is used in sports settings. The validity of the individual item scores has yet to be established.
To investigate the validity of the FMS DS by comparing the sagittal plane kinematics of participants who achieve different observer scores.
Seventeen injury-free, adolescent male cricket bowlers were assessed. The movement was captured using the Optitrack motion capture system. Simultaneously, observers scored participants' execution of the DS according to the standard FMS scoring criteria. Participants were grouped into Group 1 (lowest score), Group 2 (altered movement mechanics) or Group 3 (perfect score) according to observer scores. Specific joint angles of each group were compared using the Kruskal-Wallis and Mann-Whitney U tests.
There were significant differences in the degree to which the femur passed the horizontal between Group 3 and Group 1 ( = 0.04, = 0.61) and Group 2 and Group 1 ( = 0.03, = 0.66) and the difference in the degree to which the torso was kept vertical between Group 3 and Group 1 ( = 0.02, = 0.66) and Group 2 and Group 1 ( = 0.02; = 0.72).
Kinematic differences exist between participants who achieve different observer scores for the FMS DS.
While differences in sagittal plane kinematics have been observed in participants scoring high on the FMS DS and participants scoring low, further investigation into the validity of the frontal plane kinematics is warranted, as well as the concurrent validity of the individual scoring criteria.
功能性动作筛查（FMS）用于评估动作质量，包括在运动场景中使用的深蹲动作（DS）。单个项目得分的有效性尚未确定。
通过比较获得不同观察者评分的参与者在矢状面的运动学，研究FMS深蹲动作（DS）的有效性。
对17名无伤病的青少年男性板球投球手进行评估。使用Optitrack动作捕捉系统记录动作。同时，观察者根据标准FMS评分标准对参与者的深蹲动作执行情况进行评分。根据观察者评分，将参与者分为第1组（最低分）、第2组（动作力学改变）或第3组（满分）。使用Kruskal-Wallis检验和Mann-Whitney U检验比较每组的特定关节角度。
第3组与第1组（P = 0.04，效应量 = 0.61）以及第2组与第1组（P = 0.03，效应量 = 0.66）之间，股骨越过水平线的程度存在显著差异；第3组与第1组（P = 0.02，效应量 = 0.66）以及第2组与第1组（P = 0.02；效应量 = 0.72）之间，躯干保持垂直的程度存在差异。
在FMS深蹲动作（DS）中，获得不同观察者评分的参与者之间存在运动学差异。
虽然在FMS深蹲动作（DS）得分高的参与者和得分低的参与者之间观察到了矢状面运动学的差异，但有必要进一步研究额状面运动学的有效性以及个体评分标准的同时效度。
