Summary:Purpose : Scapular dyskinesis, it have been shown to be common in overhead athletes and has been associated with RC muscle strength. Posterior shoulder tightness (PST) has been suggested as an important factor causing scapular dyskinesis. Therefore, rehabilitation programs should focus on a posterior shoulder stretch combined with scapular stabilization exercise (PSSE) intervention. Determine the effects of posterior shoulder stretch combined with scapular stabilization exercise on the rotator cuff (RC) muscles strength, functional strength ratio (FSR), range of motion (ROM), and pain. Methods : 30 adolescent baseball players participated and subjects were allocated PSSE group (n=15) or the SSE group (n=15). Both group performed a 6-weeks intervention and measured of isokinetic peak torque/body weight (PT/BW) of concentric external rotator (CER), eccentric external rotator (EER), concentric internal rotator (CIR), eccentric internal rotator (EIR), FSR, ROM, and pain. Results : After 6 weeks PSSE, significant increase CER PT/BW (+6.02±4.76 %), EER PT/BW (+5.39±4.22 %), EER to CIR ratio (+.17±.16), and internal rotation ROM (+15.08±3.57 °). Whereas, significant decrease EIR to CER ratio (-.14±.18), external rotation ROM (-12.00±6.94 °), and GIRD (-17.41±2.84 °) compared with pre-intervention. No significant difference of isokinetic PT/BW of CIR and EER post-intervention. In the SSE group showed no significant difference all measurements for isokinetic PT/BW, FSR, and ROM post-intervention. The pain was significant improve both PSSE group (-3.25±1.60) and SSE group (-2.83±1.85) post-intervention. Conclusion : Both the PSSE and SSE interventions led to more pain relief. However, only the PSSE group showed ROM, CER, EER PT/BW, and FSR improvements. These results might suggest that the PSSE intervention is a more effective program for improving RC muscle strength and balance, in particular, concentric and eccentric ER muscle strength, FSR and can expect to prevent shoulder injuries in adolescent baseball players with scapular dyskinesis.
