The Effect of Six Weeks of Corrective Exercises on the Kinematics of the Scapula in Males with Scapular Downward Rotation Defect: A Randomized Clinical Trial

Background and Objectives: One of the abnormal forms of scapular malalignment is the scapular downward rotation defect, which includes depression, protraction, and anterior scapula tilt, which potentially reduces the upper rotation and posterior tilting of the scapula. Therefore, the aim of this study was to determine the effect of six weeks of corrective exercises on the kinematics of the scapula in males with scapular downward rotation defect. Materials and Methods: This randomized clinical trial was performed in the Faculty of Physical Education of Kharazmi University in 2019, Iran. Twenty-four eligible patients were selected and randomly divided into two equal groups of 12, corrective exercises and control group. The control group did not receive any specific treatment during the study. The scapular upward rotation and scapular posterior tilt were measured in the same way before and after the corrective exercises in the intervention group by Noraaxonchr('39')s MyoMotion 3D device. Data were analyzed using two-way repeated measures ANOVA and paired t-test. Results: A significant increase was observed in scapular upward rotation in the angles of 30º (p=0.038), 60º (p<0.001), 90º (p<0.001) and 120º (p<0.001), and in scapular posterior tilt‎ in the angles of ‎30º (p<0.001), 60º (p< 0.001), 90º (p<0.001) and 120º (p<0.001) after applying the exercise intervention in the intervention group compared to the control group. Conclusion: The results showed that the intervention of scapular correction exercises improves the angles of scapular upward rotation and scapular posterior tilt‎ in people with scapular downward rotation defect. Key words: Corrective exercises, Scapular kinematics, Scapular downward rotation defect‎   Funding: This study did not have any funds. Conflict of interest: None declared.
