ASSOCIATION BETWEEN SCAPULAR DYSKINESIS AND SHOULDER PAIN IN WEIGHT TRAINING PRACTITIONERS

Abstract

Objective: To investigate the presence of scapular diskynesis and analyze their possible association with shoulder pain in weight training practitioners. Material and Methods: Thirty seven men, practitioners of weight training participated of this study. The questionnaire Penn Shoulder Score translated into Portuguese language (PSS-Brasil) was applied to evaluate pain in rest, during activities of daily living and during the effort. Subsequently the Slide Lateral Scapular Test was applied to investigate the presence of scapular diskynesis. In order to confirm the association between pain and scapular diskynesis we used the chi-square test with Yates’s correction and calculated the odds ratio (OR). A significance level of 5% was adopted. Results: Scapular dyskinesis and shoulder pain were identified in 30 and 35 subjects, respectively. A significant association was found between the presence of dyskinesia and pain during the effort (p = 0.006). Also, the subjects with scapular dyskinesia were found to be 16 times more likely to refer pain in this condition. Conclusion: Considering the association between shoulder pain and scapular dyskinesia during efforts in weight training practitioners and that muscle strengthening can be used as a strategy to prevent scapular dyskinesia and shoulder injuries, it is important to perform a careful and appropriate assessment before indicating exercises under these conditions.
