SANTANA, Elis Passos; FERREIRAR, Bruno César and RIBEIRO, Gabriel. Association between scapular dyskinesia and shoulder pain in swimmers. Rev Bras Med Esporte [online]. 2009, vol.15, n.5, pp. 342-346. ISSN 1806-9940. http://dx.doi.org/10.1590/S1517-86922009000600004.
The scapula plays an essential role in the throwing motion performed by athletes. Scapular dyskinesia is a condition characterized by imbalance in the structures responsible for the joint stability, which is often accompanied by shoulder pain. The main objective of this study is to assess the relationship between scapular dyskinesia and shoulder pain in swimmers. A total of 36 male swimmers aged between 18 and 36 years were diagnosed for scapular dyskinesia utilizing two different methods: the Lateral Slide Scapular Test and the video recording method suggested by Kibler. Statistical analysis was performed using the Chi-square test or Fisher's exact test. Comparisons between groups were performed using the t-test. The degree of p< 0.05 was considered statistically significant. Significance was set at α=0.05. There was a high inter-rate reliability concerning the video analysis (Kappa; p<0.0001), corresponding to 86.1% (0.7656) on the right shoulder and 83.3% (0.6412) on the left shoulder. The majority of the individuals that had positive diagnosis assessed by the Lateral Slide Scapular Test (80%) reported pain on the shoulder. Furthermore, 70.8% of the subjects who had positive diagnosis by the video recording also had positive diagnosis in the static test. Although a significant association between scapular dyskinesia and shoulder pain was not found, this is an important study to approach these conditions in swimmers.
