Background: This study was designed to examine the effect of an 8-week rehabilitation training program on electromyography activity of shoulder girdle muscles in the overhead throwing ath-letes with scapular dyskinesis. Methods: Thirty-eight female athletes (volleyball players, n = 20 and handball players, n = 18) participated in this study and were randomly assigned into two groups including experimental (n = 20, volleyball n = 10, and handball, n = 10) and control (n = 18, volleyball n = 10, and handball n = 8) groups. Before and after 8 weeks rehabilitation training program, the electrical activity in the upper (UT), middle (MT), lower trapezius (LT), serratus an-terior (SA), and infraspinatus (IS) muscles were measured at abduction movement in the shoul-der (30° anterior to frontal surface). Results: After 8 weeks of training program, the electrical ac-tivity of the UT muscle significantly decreased for the EXP group (0-45°, p = 0.001; 0-90°, p = 0.001, and 0-135°, p = 0.001), and in comparison to CG (0-45°, p = 0.001; 0-90°, p = 0.001, and 0-135°, p = 0.001). The electrical activity of the MT, LT, SA, and IS muscles significantly in-creased for the EXP group (0-45°, p < 0.05; 0-90°, p < 0.05, and 0-135°, p < 0.05) after 8 weeks of training intervention, and in comparison to CG (0-45°, p < 0.05; 0-90°, p < 0.05, and 0-135°, p < 0.05). Conclusions: An 8-week rehabilitation training program succeeded in decreasing activity of UT muscles and increasing activity of SA, LT, MT and IS resulting in rehabilitation of the overhead throwing athletes with scapular dyskinesia.
