ANGULAR KINEMATICS OF THE DEEP SQUAT TEST IN FUNCTIONAL MOVEMENT SCREEN™ ACCORDING TO THE SCORING SYSTEM

The aim of this study was to determine to angular kinematic differences of the Functional Movement Screen (FMS) TM deep squat test according to the classifications. 23 university students (age 22.43 +/- 1.53yrs; height 177.26 +/- 6.09cm and weight 70.21 +/- 12.40kg) participated to this study voluntarily. Participants performed a deep squat test three times according to Cook's guidelines for Functional Movement Screening. They get scored by a clinician as 1, 2 or 3. During the test performance, 3D angular kinematic data was collected by 8 high speed Oqus 7+ cameras which were connected directly to the computer. Left and right knee, hip and shoulder angles; trunk flexion angle; hip, calf segmental angles, dowel angle in frontal axis; and also thigh segmental angle in horizontal axis were assessed to examine differences between the three scoring groups by using Qualisys Track Manager (QTM) Version 2.12. SPSS 18.0 (SPSS Inc., Chicago, IL, USA) program was used for the differences by Kruskal Wallis test. As a result of the study, the significant difference were found at right and left knee angle between groups (p<0.05). Also in horizontal plane, right and left thigh were significantly difference between groups (p<0.05) too. There were no significant differences found in other parameters. (p>0.05). As a conclusion, in squat movement, as the limitation of motion increases, the hip and knee angles were getting higher and because there was a knee excursion in the horizantal plane, the mechanics of movement distorted.
