Abstract
The purpose of this research was to investigate the effect of scapular kinetic chain exercises on function, scapulohumeral rhythm and position sense of shoulder joint in gymnasts with scapular dyskinesia. 30 gymnasts with scapular dyskinesia were randomly divided into two experimental (15 people) and control (15 people) groups. To evaluate the scapular movement disorder, using Kibler's scapular dyskinesia and lateral scapular slid test, to measure the scapulohumeral rhythm using a goniometer, to evaluate the feeling of the shoulder joint position using the photography method (45 and 80 degrees) and to evaluate the shoulder function using the YBT-UQ test was used. Then, the experimental group participated in scapular kinetic chain exercises for 8 weeks, and again the initial tests of the two groups were performed and the results were recorded and analyzed. The results of the research findings showed that there was a significant difference between the shoulder joint function, scapulohumeral rhythm and feeling of shoulder joint position at 40 and 80 degree angles in the two groups after the test (p=0.001). Also, there was a significant difference between shoulder joint function, scapulohumeral rhythm and feeling of shoulder joint position at 40 and 80 degree angles in the pre-test and post-test of the experimental group, while this difference was not significant in the control group. According to the research findings, it seems that exercises are useful for gymnasts with scapular dyskinesia; Therefore, it can be recommended to rehabilitation specialists, trainers and gymnasts as beneficial exercises.
