Purpose : The purpose of this study is to investigate the effect of each lower trapezius muscle exercise performed according to the abduction position (Y type - shoulder joint abduction 145 °, T type - shoulder joint abduction 90 °, and MPC type - shoulder joint 45 ° abduction) of the shoulder joint on the muscle activity of the round shoulder and lower trapezius muscle. Methods : This study was conducted on 31 adult men and women. Through random assignment, they were assigned to the Y group, T group, and MPC group. A 4-week intervention was performed for each group of 31 subjects who participated in the experiment, and shoulder height and lower trapezius muscle activity were measured before and after the intervention. Shoulder height measurement is a test to measure rounded shoulder posture. When the value is low, it means that rounded shoulder posture is improved. The muscle activity of the lower trapezius muscle was measured using the %MVIC method, and when the value is high, it means that the lower trapezius muscle is active. All measured data were verified using dependent t-tests for before and after comparisons and one-way analysis of variance for comparisons between groups. Results : The results of this study showed a significant decrease after intervention only in shoulder height. Muscle activity of the lower trapezius muscle decreased after intervention, but did not show a significant difference. Both variables showed no significant differences between groups. Conclusion : The results of this study show that three lower trapezius muscle exercises were performed on subjects in rounded shoulder posture. All three groups showed a significant decrease in the shoulder height value, a method of measuring rounded shoulder posture, and no significant differences between groups could be confirmed. Therefore, all three exercises can be considered effective in reducing shoulder posture.

Purpose: The purpose of this study was to assess the effectiveness of Extracorporea Shock - Wave Therapy (ESWT) on the pain and improvement of shoulder joint function which is one of the available medical treatment in patients with frozen shoulder. Object and Methods: 26 patients with frozen shoulder, with 26 patients assigned to two groups; a control treatment group (n=12) and a ESWT application group (n=14). In the ESWT application group, the patients received general physical therapy, and then they received ESWT. In the control treatment group, the patients received only general physical therapy. These medical treatments was conducted total 6 time for 3 weeks. To investigate the effectiveness of the treatment after the each group's treatment. Pain was measured by Visual Analogue Scale (VAS) which is divided into 10 ranks and shoulder joint function was measured by CSA(Constant Shoulder Assessment scale). Results: 1. There was a statistical significance of measured by shoulder pain degree in both group but, the result of a ESWT application group shows more significance than that of a control treatment group. 2. There was a statistical significance of measured by CSA in both group but, the result of a ESWT application group shows more significance than that of a control treatment group. Conclusion: We think that treatment with General physical therapy and ESWT together for the patients with frozen shoulder is more effective and more safe method to shoulder joint function improvement and decrease of pain.

Background: To evaluate clinical and radiological outcome using AO hook locking plate in acute acromioclavicular joint injuries. Methods: This study was based on patients with Rockwood type 3 or 5 acromioclavicular joint injuries who received surgery with AO hook locking plate from June 2008 until June 2009. Among the 22 patients, 19 of them were male and 3 were female, the mean age was $44.4{\pm}15.57$ years (20-72 years) and follow-up period was $15.5{\pm}3.90$ months (12-23 months). Preoperatively, postoperatively, and at the final follow-up after the plate removal, both coracoclavicular distances were measured from the anteroposterior radiograph. Also, the Shoulder Rating Scale of the University of California at Los Angeles scores (UCLA scores), the American Shoulder and Elbow Surgeons scores (ASES scores), Constant scores, and the Korean Shoulder Society scores (KSS scores) were measured at the final followup to evaluate the function of the shoulder joint. Results: At the time of injury, the mean coracoclavicular distance of the injured side was $17.69{\pm}4.23mm$ (9.57-27.82 mm) and the unaffected side was $7.55{\pm}2.20mm$ (3.24-13.05 mm). The mean coracoclavicular distance measured postoperatively and at the final follow-up was $6.87{\pm}2.34mm$ (4.07-14.13 mm) and $8.47{\pm}2.96mm$ (4.37-17.48 mm), respectively. The mean UCLA, ASES, Constant, and KSS scores measured in the final follow-up were $33.5{\pm}1.30$ (31-35), $90.8{\pm}8.36$ (72-100), $78.6{\pm}8.80$ (62-100), and $94.4{\pm}5.08$ (84-100) each. Conclusions: From this short-term research, the surgical treatment using AO hook locking plates in acute acromioclavicular joint injuries is clinically and radiographically satisfying and considered as a useful treatment method.

The shoulder joint permit ate greatest mobility of any joint area carries out the importment function of stabilization for hand use. So handgrip activity is important to evaluate while assessing shoulder load in manual work. There was an association between static handgrip and shoulder muscle activity. The purpose of this study was to find out the changes of the hand grip strength according to shouter an81e. One hundred (50 female, 50 male) college adult volunteers with no known shoulder dysfunction participated subject in three positions with elbow extension: (1) shoulder $0^{\circ}$ flexion (2) shoulder $90^{\circ}C$ flexion (3)shoulder $180^{\circ}C$ flexion. The paired t-test was used to determine the different in grip strength between right and left hand at shouter position change. All, there was significiant for all three position by right and left shoulder (p<0.001). In mon, the ANOVA results revealed not a significiant F-ratio fer all three position by right and left hand. In woman, revealed significiant (p<0.05).

Multidirectional instability of the shoulder joint is an unusual entity which is not yet well understood. Traditionally recommended treatment is non-operative, but recently arthroscopic treatment has been performed. This is a retrospective review of 20 patients who had multidirectional instability, who had been treated with arthroscopic capsular shift(7 cases), and arthroscopic treatment using Ho:YAG laser(l3 cases) at Department of Orthopaedic Surgery, Chungnam National University Hospital from July, 1988to February, 1997. Results of this study were as follows: 1. In five patients who were treated with arthroscopic anterior capsular shift only, all cases had redislocation of the shoulder joint. But there was no redislocation in two patients who were treated with arthroscopic anterior and posterior capsular shift. 2. ln three patients who were treated with laser-assisted capsular shift only, all cases had redislocation of the shoulder joint. But there was only one redislocation in ten patients treated with laser-assisted capsular shrinkage and capsular plication. Ho: Y AG laser has been found to be a safe and efficacious adjunct to many arthroscopic shoulder procedures. We had satisfactory results by combining a transglenoid capsular shift with laser-assisted capsular shrinkage. Arthroscopic laser-assisted capsular shrinkage and capsular plication is a one of recommendable treatment options in multidirectional instability of the shoulder joint.

The purpose of this study was to comparatively analyze the active stability of shoulder joints according to the frequency of overhead motions, such as serving and spiking, engaged in by female professional volleyball athletes who play different positions, and to provide the results as the basic data for developing exercise programs to prevent shoulder joint injuries. The subjects of this study were 50 Korean female professional volleyball players and positions were as follows: left and right attackers, centers, setters, and liberos. The external rotation and internal rotation muscle strength and muscle strength ratios of the dominant and non-dominant arms of all subjects were measured using Biodex. The results of this study are as follows: Frist, no significant differences were found in the internal and external rotation muscle strength of the dominant and non-dominant arms between positions. Second, for the shoulder joint muscle strength ratio of the dominant arm, by position, the setter showed significantly greater stability compared to the other positions. Third, for the shoulder joint muscle strength ratio of the non-dominant arm, by position, no significant difference in stability between positions was found. Fourth, it was found that the dominant arm had significantly greater instability of the shoulder joint than the non-dominant arm for attackers and centers, but no significant difference was found for setters and liberos. This study comparatively analyzed the muscle strength ratios of the external/internal rotations and dominant/non-dominant arms, which can determine the stability of the shoulder joints between female professional volleyball playing positions that engage in jumps and spikes using only the dominant hand and positions that do not.

Purpose : The purpose of this study is to analyze the corrective effect of the general coordinative manipulation (GCM) joint intervention model on distort leg with imbalance of the lower extremity joints, pelvic and shoulder girdles, and lumbar spine. Methods : The study used a comparative analysis of the size of the distort leg and the imbalance of the lower extremity joints, pelvic and shoulder girdles, and lumbar spine before and after the application of the GCM joint intervention model. A total of 31 subjects from movement center G and the department of physical therapy at university M were selected as research subjects, and they were divided into two groups. The GCM joint intervention model was applied to 18 subjects in the bow knee group and 13 subjects in the knock knee group. The two groups received daily intervention three times a week for four weeks. The corrective effect of the GCM joint intervention model for each type of distort leg was compared and analyzed. Results : The effects of the GCM joint intervention model in correcting bow knee and knock knee with knee deformation and imbalance of the lower extremity joints, pelvic and shoulder girdles, and lumbar spine were significant in most domains (p<.05). The correlation between the bow knee and knock knee groups showed significance in most domains (p<.05). Conclusion : The GCM joint intervention model showed significant corrective effect in the bow knee and knock knee groups in terms of knee deformation, lower extremity joints, pelvic and shoulder girdles, and lumbar spine (p<.05).
