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.

Purpose: The purpose of this study was to determine how a shoulder complex stabilization exercise affects ball control and ball speed in elementary school baseball players with an instable scapula. Methods: The subjects of the study were 16 baseball players attending S elementary school in Kwangju Metropolitan City. A shoulder complex stabilization exercise was conducted three times per week for one hour for four weeks. Then, the participants were divided into a scapular instability group or stability group based on their lateral scapular slide test scores. The measurement tool was measured using the target, the ball speed tester (PR1000-BC). All inspections were measured before and after the mediation period to examine the change in the subjects according to the mediation period. Results: As a result of measuring ball control, there was a statistically significant difference in the variation over time (p < 0.05), and there was no statistically significant difference in the interaction between time and group (p > 0.05). As a result of the test of effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). In terms of ball speed, there was no statistically significant difference found in the variation over time (p > 0.05) as well as in the interaction between time and group (p > 0.05). In terms of the effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). Conclusion: It was found that the shoulder complex stabilization exercise could improve ball control for elementary school baseball players. It is believed that this will help prevent and solve possible sport damages experienced during training or competitions, thereby helping athletes use training methods to improve their exercise capacity and continue their careers.

Background: The research examined the effect of a scapular stabilizing exercise on shoulder pain, active range of motion (AROM) and changes in the position of the shoulder blade of patients with frozen shoulder. Methods: General physical therapy and a scapular stabilizing exercise were applied to a 53-year-old female patient with frozen shoulder three times a week for four weeks. Before and after the therapy, measurements were made on the visual analog scale (VAS) and of the AROM, and a lateral scapular slide test was conducted. Results: Following the therapy, VAS fell from 7 to 3. Before therapy, flexion, abduction, internal rotation, and external rotation recorded $133^{\circ}$, $102^{\circ}$, $45^{\circ}$, and $53^{\circ}$ respectively; after the therapy they increased to $150^{\circ}$, $123^{\circ}$, $55^{\circ}$, and $65^{\circ}$ respectively. The lateral scapular slide test showed sliding distances before therapy of 8.5cm at $0^{\circ}$, 9.2cm at $45^{\circ}$, and 11.3cm at $90^{\circ}$; after therapy, the distances decreased to 6.8 cm at $0^{\circ}$, 8.2 cm at $45^{\circ}$, and 9cm at $90^{\circ}$. Conclusion: The scapular stabilizing exercise was effective in alleviating shoulder pain, increasing AROM, and reducing changes in the position of the shoulder blade of frozen shoulder patients.

Background: Scapular winging is a rare disorder that is commonly caused by nerve damage of the dorsal scapular nerve, spinal accessory nerve, or the long thoracic nerve. This affects the scapulohumeral rhythm which may cause abnormal kinetic motion of the shoulder. The purpose of this case report is to describe a self-exercise oriented management incorporating shoulder strengthening to reduce symptoms in a shoulder pain patient with winging scapular. Methods: A 45 year old male patient complained of pain in his both shoulders without any trauma. Shoulders were treated with steroid injections for supraspinatus tendonitis, but although pain improved to some extent, pain and disability continued for 3 months. Both shoulders had pain, decreased active range of motions, muscles weakness, and scapular winging. The patient underwent 9 interventional sessions over 3 months and was managed mainly by self-exercise. The intervention method involved push up plus, sling, muscle strengthening, and stabilization exercises. Loads were increased as symptoms improved. Results: Clinical outcomes were measured at every session. Pain in both shoulders reduced to 0 on a numerical pain rate scale by the 4th session, and the active range of motion was fully recovered. During the 9th session, the strength of the serratus anterior had improved from grade P to G on the right side and grade G to N grade on the left. Conclusion: In this case study, the self-exercise program was effective in reducing pain, increasing active range of motion, and improving muscle strength in subjects with scapular winging.

Background: Twenty-six patients (12 male and 14 female) with symptomatic scapular winging caused by serratus anterior dysfunction were managed by split pectoralis major tendon transfer (sternal head) with autogenous hamstring tendon augmentation from 1998 to 2006. Methods: Twenty-five patients showed positive results upon long thoracic nerve palsy on electromyography. The mean duration of symptoms until surgery was 48 months (range, 12-120 months). Four patients had non-traumatic etiologies and 22 patients had traumatic etiologies. On follow-up assessment for functional improvement, a Constant-Murley score was used. Twenty-one patients were completely evaluated, while five patients who had less than 12 months of follow-up were excluded. Results: Pain relief was achieved in 19 of the 21 patients, with 20 patients showing functional improvement. The pain scores improved from 6.0 preoperatively to 1.8 postoperatively. The mean active forward elevation improved from $108^{\circ}$ (range, $20^{\circ}-165^{\circ}$) preoperatively to $151^{\circ}$ (range, $125^{\circ}-170^{\circ}$) postoperatively. The mean Constant-Murley score improved from 57.7 (range, 21-86) preoperatively to 86.9 (range, 42-98) postoperatively. A recurrence developed in one patient. Of the 21 patients, ten had excellent results, six had good results, four had fair results, and one had poor results. Conclusions: Most patients with severe symptomatic scapular winging showed functional improvement and pain relief with resolution of scapular winging.

이 연구는 일반 푸시업과 무릎 푸시업, 벽 푸시업 운동시 어깨 안정근의 활성도 차이를 알아보는데 목적이 있다. 연구대상은 어깨관절에 통증이 없고 푸시업 운동을 하지 않은 대학생 남자 8명을 대상으로 하였으며, 어깨 안정근의 활성도를 알아보기 위하여 표면 근전도를 이용하여 위등세모근, 아래등세모근, 중간등세모근, 앞톱니근, 앞세모근, 뒤세모근, 큰가슴근, 가시아래근에 부착하였다. 일반 푸시다운은 무릎 푸시다운과 벽 푸시다운 보다 근활성도가 유의하게 더 큰 것으로 나타났다. 푸시업 동작에서는 앞톱니근과 가시아래근이 다른 어깨안정근에 비해 근활성도가 유의하게 더 컸으며, 일반 푸시업 동작이 무릎 푸시업과 벽 푸시업 보다 근활성도가 유의하게 더 큰 것으로 나타났다. UT/LT 비율에서는 무릎 푸시다운이 벽 푸시다운 보다 유의하게 낮았으며, UT/SA 비율은 푸시다운과 푸시업 모두 통계적으로 유의한 차이는 없었다. 결론적으로 푸시업과 푸시다운 동작 시에는 앞톱니근과 앞어깨세모근, 가시아래근이 다른 어깨안정근보다 근활성도가 높고, 일반적인 푸시업 운동이 무릎 푸시업과 벽 푸시업 운동보다 근활성도 측면에서는 더 효과적이다. 그러나 푸시다운을 할 경우에는 어깨안정화를 위해 무릎을 굽힌 상태에서 푸시다운을 하는 것이 더 효과적인 것으로 사료된다.
