Purpose: The purpose of this study was to investigate any visible difference in shoulder stability muscle activity along the bending angle($70^{\circ}$, $90^{\circ}$, $110^{\circ}$) to perform the open kinetic chain(OKC) and closed kinetic chain(CKC) exercise. Method: This study was performed on normal 20 males subjects. Exercise was carried out in two ways OKC and CKC. Shoulder stability muscles are examined activity in the bending angles. In the OKC and CKC exercise to subjects with stretched out waist straightened, and than push forward the shoulder. Muscular activation was examined using the WEMG-8. Result: The results of this study were as follows. 1. Only in the trapezius muscle, it showed specific interaction between exercise methods and angles. When it comes to muscle activity, there was no significant difference in all muscles except for the anterior fibers of the deltoid muscle during both CKC and OKC exercise. 2. The average value of maximum muscle activity was significantly increased with increasing order of angles. But in CKC exercise, the muscle activity of infraspinatus tended to decrease with increasing angles. Conclusion: To summarize the research results, the muscle activity in upper fibers of the trapezius, anterior fibers of the deltoid, and serratus anterior was significantly different depending on the angle of the shoulder in both CKC and OKC exercise.

Background: The purpose of this study is to analyze the effect of shoulder and neck stabilization exercise using a gym ball for healthy women in their 20s with round shoulder and forward head posture, it is intended to try and find improvement for posture. Methods: The subjects of the study were 25 women who understood the purpose of the research and voluntarily agreed to participate in the experiment. They carried out the shoulder and neck stabilization exercise program using a gym ball, which was conducted for 35 minutes, 3 times a week for 4 weeks. The position of the round shoulder and shoulder bones was measured using an tape measurement and were recorded in both at pre, 2 weeks, and post intervention. The craniovertebral angle (CVA) and craniorotational angle (CRA) was measured using an image J. Results: The round shoulder posture left was statistically significantly different within group (p<.05); however, the round shoulder posture right wasn't statistically significantly different (p>.05). As a result of this contrast, test were significant different in both at pre, 2 weeks and post. The scapular position on the left and right were statistically significantly different within the group (p<.05). As a result of the contrast, test were significant different in both at pre, 2 weeks and post (p<.05). The CVA and CRA on the left and right were statistically significantly different within the group (p<.05). As a result of the contrast, test were significant different in both at pre, 2 weeks and post (p<.05). Conclusion: The gym ball exercises improved the posture of women in their 20s.

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.
