        Background: Child care center teachers are exposed to musculoskeletal injuries caused by repetitive movements at low heights due to the nature of their jobs. Self-myofascial release (SMFR) improves flexibility, pain, and functional performance. Pectoralis minor self-stretching (PMSS) improves muscle flexibility and postural alignment. PMSS has been commonly used to correct a rounded shoulder posture (RSP). Objectives: To examine the shoulder height, muscle tone, muscle stiffness, and muscle elasticity for women child care center teachers with RSP. Design: Randomized study. Methods: The participants were 20 women child care center teachers with RSP. They were randomly assigned two groups: SMFR group (n=10) and PMSS group (n=10). They performed each exercise for 20 min, 3 times a week for 4 weeks. They measured shoulder height, muscle tone, stiffness, and elasticity of upper trapezius before and after exercise. Results: In the shoulder height, there was no significant difference between two groups. There were significant decreases within both groups. In the muscle tone, stiffness, and elasticity, there was no significant difference between two groups and within two groups. Conclusion: SMFR using a hard massage ball and PMSS have a positive effect on posture correction for child care center teacher with RSP.

        The purpose of this study was to identify the effects of shoulder stabilization exercises and stretching on shoulder height and muscle activity in young adults with rounded shoulder posture. The subjects were young adults with rounded shoulder posture, and divided into two groups: shoulder stabilization exercises and stretching exercises. The shoulder stabilization exercise group performed Thera band exercises and stretching exercises. The stretching exercise group performed stretching exercises. The groups performed the exercises for 40min, three times a week for four weeks. Shoulder height was measure by Vanier calipers and muscle activity was measured by electromyography. Shoulder height was significantly decreased in both groups after intervention, however there was no difference between groups. There was a significant difference in muscle activity between the two groups after the intervention, however there was no difference between the groups. This study suggests that shoulder stabilization exercise and stretching affect shoulder height and muscle activity.

        The aim of the present study was to investigate the effects of unilateral shoulder bag weight and heel heights on trunk muscle activities. This study recruited 40 healthy women in their twenties. Electromyography activities of rectus abdominis muscle, external abdominal oblique muscle, internal abdominal oblique muscle and erector spinae muscle during standing position were measured using a surface electromyography system. The overall muscle activities of the trunk muscles were significantly increased in the contralateral trunk muscles (p<.05). Inaddition, the trunk muscles overall activities on the contralateral side without the shoulder bag was positive correlation with the heel height and unilateral shoulder bag weight (p<.05). Both high-heeled wear and unilateral shoulder bags are fashion items that cause asymmetry in the trunk muscles of women in their twenties. These findings suggest that the increase in the weight and heel height of the unilateral shoulder bag in women cause asymmetry of trunk muscle activities.

        The purpose of this study is to evaluate the differences of body compensation image on variations in the shoulder height and width of power shoulder raglan sleeve jacket. Nine samples were examined: 3 variations of the shoulder height and 3 variations of the shoulder width. The data was evaluated by 123 fashion design majors. The results were as follows; as a result of analyzing the body compensation image according to changes in the shoulder height and width of power shoulder raglan sleeve jacket, five factors were selected; the shoulder compensation factor, the bust compensation factor, the waist compensation factor, the arm compensation factor and the neck compensation factor. Among these factors, the shoulder compensation factor is the most important factor. Examining the major effect of the body compensation image based on changes in the shoulder height and width of power shoulder raglan sleeve jacket, it had an independent influence on factors about waist, neck, shoulder and arm compensation except a factor about bust compensation, had an influence on interacting effect of factors about shoulder, bust, waist, arm compensation, and it had no influence on interacting effect of a factor about neck compensation. This shows that the shoulder height has larger effect on neck compensation image than the shoulder width in power shoulder raglan sleeve jacket.
