The purpose of this study is to investigate musculoskeletal symptoms and job stress of physical therapists in their 20s who are responsible for therapeutic exercise and to understand the correlation between the two. This study conducted a research on 144 subjects based on the measurement tools provided by national institution. The results are as follows. Many subjects were experiencing musculoskeletal symptoms and disorder in their hands/wrists/fingers, shoulders, and waist with high proportionate of subjects experiencing the symptoms and disorder in their right hand/wrist/finger. Among job stress, job environment, job requirement, and compensation had significantly positive correlation with physical burden(r=.297~.392, p=.000). In particular, shoulder pain intensity has significantly positive correlation with job requirement, duration of pain in hand, wrist, and fingers as well as workplace culture(r=.331~.478, p=.003~.009) which indicates that musculoskeletal symptoms are some what correlated with job stress. Based on this study, it is necessary to show more concern and make an effort to manage musculoskeletal symptoms and job stress.

The purpose of this study was to investigate the effects of cervical vertebral height and shoulder stabilization on anterior head posture in people with turtle neck. The subjects of this study consisted of normal and healthy people with 30 turtle necks. Subjects were randomly assigned to shoulder stabilization exercise and cervical vertebrae exercise (30 men, 15 men and 15 women, height: $168.67{\pm}6.51$, $22.33{\pm}8.27$, $65.03{\pm}11.98$, and $28.66{\pm}1.91$), In the experimental group, shoulder stabilization exercise and cervical spine exercise were performed for 4 weeks. Deep neck flexor, leavator scapular, upper trapezius, rhomboid, and lower trapezius showed significant differences in shoulder stabilization and cervical vertebrae before and after the experiment. As a result, the CVA value decreased significantly and the muscle activity value increased significantly when exercise and Mckenzie program were applied. These results show that exercise and Mckenzie programs have a positive effect on turtle neck improvement.

The aim of this study was to determine the effects of the action observation and visual feedback on the alignment, pain and function of forward head posture(FHP) and round shoulder(RS). A total of 24 participants with FHP and RSP were randomly assigned to general exercise(GE, n=8), action observation(AO, n=8), and visual feedback(VF, n=8). All subjects were exercised three times a week for four weeks. The groups were assessed for craniovertebral angle(CVA), round shoulder posture(RSP), visual analog scale(VAS), and neck disability index(NDI) before and after exercise, There was a significant difference in CVA in the GE, AO and RSP, VAS and NDI were significantly different in all groups. AO was more effective than GE, VF for VAS. The results of this study suggest that action observation may be effective to improve the FHP and RS.

Background: Approximately 30% of people suffer from chronic neck and shoulder pain. Chronic neck and shoulder pain arise due to the exposure to continuous low loading and monotonous work. This is a common musculoskeletal disorder in a society. As physical therapists, we should give appropriate treatment to these people. Methods: A total of 26 patients with chronic neck and shoulder myalgia were randomly allocated into two experimental groups. First, 13 patients received shoulder strength training, while the other 13 patients received cervical mobilization. Outcome measures included bilateral pressure pain threshold by using an algometer at upper trapezius, visual analogue scale (VAS) to express their pain scale, and muscle tension by using myoton pro device pre-intervention and after the final treatment. Results: The VAS and muscle tension in upper trapezius significantly decreased (p<.05) in both groups; however, no differences between two groups were observed (p>.05). The pressure pain threshold in upper trapezius significantly increased (p<.05) in both groups; yet, again, the differences between the groups did not reach statistical significance (p>.05). Conclusion: As methods of treatment, shoulder-specific strength training and cervical mobilization can be appropriate approaches to the treatment of neck and shoulder musculoskeletal disorder.

The purpose of this study is to improve pain and injury through bicycle fitting and to propose rehabilitation methods. Pain and injuries caused by bicycles can be largely divided into knee and ankle pain, wrist, shoulder, neck, and back pain, and hip pain. The cause of these pains and injuries stems from incorrect bicycle fitting and posture. In order to improve these pain and injuries and prevent recurrence, appropriate bicycle fitting and rehabilitation exercise are needed. Pain and injury are divided into kinetic pain and pain by a fixed posture. In the case of kinetic pain, rehabilitation exercise is required along with inflammatory treatment, and pain by a fixed posture should understand the exact characteristics of the body and learn and practice bicycle posture according to the body's characteristics. Through this method, it can contribute to preventing the recurrence of bicycle pain and injuries and further creating an environment where a safe bicycle culture can be established.

Shoulder joint pain is a very common musculoskeletal disorder, in which about 20 percent of adults experience it more than once in their lives. In this study, an objective assessment was made that subacromial space was increased by pectoralis minor stretching exercise, which has a positive effect on impingement syndrome and shoulder pain. Also, This study examined the effects on pectoralis minor length(PML) and acromio-humeral distance(AHD) following pectoralis minor self-stretching exercise in normal adults. In this study, a total of 30 subjects were recruited and randomly divided into a self-stretching exercise group(n=15) and manual stretching exercise group(n=15) to compare the immediate effects of treatment. Studies have shown that both groups have significantly increased both PML and AHD within the group(p<.05). There was no statistically significant difference in the comparison between the groups(p>.05). The results suggest that self-stretching exercise can be recommended as a treatment method for impingement syndrome and prevention of shoulder disease.

Rotator cuff tears are a leading cause of shoulder pain in adults. Due to the increase in social activities, the number of patients complaining of shoulder pain is increasing, and interest in shoulder diseases is also increasing. With the development of ultrasound equipment, the sensitivity and specificity of diagnosis are high, and it is used to diagnose rotator cuff tears in musculoskeletal disease. Ultrasound is recognized as a complementary method to MRI examination in rotator cuff tears. Therefore, this study aimed to find out the diagnostic usefulness of ultrasound and MRI examinations in the diagnosis of shoulder rotator cuff tears.A retrospective analysis was performed on 262 patients who were diagnosed with final rotator cuff damage by arthroscopy after completing ultrasound and MRI examinations. Sensitivity, feature, positive predictive value, image predictive value, and touch were disassembled for the test results. In addition, the degree of clavicular tear was scored and recorded in 5 stages. Ultrasound examination was similar to MRI examination results for both full-thickness and partial tears, and there was no statistically significant difference. Partial tear test results showed higher positive predictive value and accuracy than MRI test. In conclusion, ultrasound can be fully utilized as a screening test for rotator cuff disease, and it is thought that it will be selected and used clinically according to the patient's constitution and situation.

We verified reason of pain by rotator cuff disease using shoulder sonography and found a correlation between shoulder pain and stress. To find out the accuracy of sonographic prediction of rotator cuff disease among the patients with shoulder pain we surveyed 184 patients in S hospital in Seoul Korea between January to October 2012. These patients were previously diagnosed with the torn rotator cuff, adhesive capsulitis and impingement syndrom with shoulder pain. In most times, the rotator cuff disease was diagnosed among the physical workers who use shoulder excessively and also in the women in their 50~60 years of age(144 patients, 78.3%). There were significant correlation between rotator cuff disease and the stress of pain, between sonographic prediction and pain(p<.05). There were significance between shoulder pain and stress in daily life according to result for survey of BEPSI-K(p<.05).
