Abstract

Background and Aims: The visible changes in the scapular position and motion are called scapular dyskinesis. Drawing a high poundage archery bow increases tissue pressure in the shoulder joints of archers, causing pain and decreasing performance and proprioception in the shoulder joint. The aim of the present study was to determine the effect of eight weeks of scapular stabilization exercises on the performance and shoulder proprioception of archers with scapular dyskinesis.
Materials and Methods: A total of 30 archers with SD and shoulder pain were selected and then randomly divided into two experimental and control groups (15 in each group). Proprioception assessment and performance were measured in all samples. Then, the experimental group performed scapular stabilization exercises (i.e. scapular retraction, push-up with plus, etc.) for eight weeks, three sessions per week and 40 minutes per session. The control group performed no exercise. At the end of the training, post-test was run for both groups. The covariance test was used to compare the differences between the research variables in the control and experimental groups.
Results: The results of the current study showed that scapular stabilization exercises improved performance and proprioception of shoulder joint with scapular dyskinesis (p < 0/05) in both intra-group and inter-group comparisons. But in the intergroup comparison, the exercises did not show a significant effect on proprioception of shoulder joint without scapular dyskinesis (P˃0.05).
Conclusion: According to the results of the present study, scapular stabilization exercises can be used to improve performance and proprioception in the shoulder joint of archers with scapular dyskinesis.
