Background: The objective of this study was to compare the efficacies of thoracic self-mobilization and strengthening exercise in young adults with thoracic hyperkyphosis. Methods: The subjects were 30 young adults (11 males, 19 females) with thoracic hyperkyphosis. They were randomly assigned to one of three groups: thoracic self-mobilization, thoracic strengthening exercise, and control group. The thoracic self-mobilization group performed active dynamic exercises, which included thoracic extension and rotation in supine and standing positions. The strengthening exercise group performed resistance exercises involving the back extensor muscle, with an elastic band and dumbbells. The outcome measures were the thoracic kyphosis angle and forward head posture (craniovertebral angle [CVA] and cranial rotation angle [CRA]). Results: Compared with the baseline values, the thoracic kyphosis angle had decreased while the CVA had increased in both training groups (p<.05), but the CRA was significantly decreased in only the strengthening exercise group. Thoracic self mobilization reduced kyphosis and improved CVA, while thoracic strengthening exercise reduced kyphosis and improved CVA and CRA. Conclusion: This study suggests a promising exercise intervention that can improve posture in young adults with thoracic hyperkyphosis.

Objective: The purposes of this study was to evaluate the diagnostic values of abdominal muscles thickness and sterno-costal angle as the quantitative diagnostic indicators for young adults with rounded shoulders. Design: A observational, cross-sectional study. Methods: This study included thirty-three male participants in order to examine the relationship among thoracic kyphosis, sternocostal angle, and abdominal muscle thickness. We used ultrasound imaging to measure the muscle thickness, two gravity-dependent inclinometers to measure the kyphosis angle, and Image J to measure the sterno-costal angle. Results: There was a significant positive correlation between the amount of thoracic kyphosis angle and muscle thickness of the external oblique (EO) on the right side (r=0.931), and on the left side (r=0.432), and the transverse abdominis (TrA) (r=0.649). There was also a significant negative correlation between the thoracic kyphosis angle and the sterno-costal angle at the right side (r=-0.942) and at the left side (r=-0.860). There was a significant positive relationship with muscle thickness of the EO and TrA on the right side with the thoracic kyphosis angle, and was significant negative relationship with the sterno-costal angle on both sides. Conclusions: The results of the study suggest that the thoracic kyphosis angle is related to muscle thickness of the EO and TrA on the dominant side and the sterno-costal angle. We also suggest that future studies are needed to determine how strengthening the abdominal muscles may contribute to preventing excessive thoracic kyphosis in young adults.

Objective: The purpose of this study was to investigate the effect of thoracic spine and ankle joint alignment on trunk and upper limb muscle activity during trunk forward lean exercise using a sling. Methods: 25 subjects participated in this study. All subjects performed trunk forward lean exercise using a sling under four conditions according to the alignment of the thoracic spine and ankle joints. Trials were performed 3 times in each condition. Muscle activity of the trunk and upper extremity was measured using electromyography. Results: In the dorsiflexion, the thoracic kyphosis condition showed significantly higher muscle activity in the pectoralis major, rectus abdominis, latissimus dorsi, transverse abdominis than dorsiflexion(p<0.05). In the plantar flexion, thoracic kyphosis condition showed significantly higher muscle activity in pectoralis major, transverse abdominis, latissimus dorsi muscle activity than dorsiflexion(p<0.05). Conclusions: Regardless of ankle alignment, thoracic kyphosis condition increased the activity of the pectoralis major, transverse abdominis, latissimus dorsi. Therefore, regardless of the alignment of the ankle, it is recommended to perform the trunk forward lean exercise using a sling in thoracic kyphosis.

Scapular position and motion are essential for normal upper limb mobility; Further, the posture of patients with thoracic kyphosis is related to shoulder girdle function and disorder. The purpose of this study was to examine the effects of thoracic posture on the shoulder range of motion and on three-dimensional scapular kinematics. Thirty healthy subjects performed right-arm abduction along the frontal plane while standing in both erect and in slouched trunk posture. The scapular position and rotation, and shoulder and thoracic angles were recorded using a motion analysis system. The scapular upward rotation and internal rotation were significantly altered according to postural tatiges; however, scapular tilt was not affected. Shoulder angle was significantly decreased in the slouched posture as c rpared to tatt in the erect posture. Thus, a slouched posture(thoracic kyphosis) significantly affects the shoulder range of motion and scapular kinematics during shoulder abduction in the frontal plane.

Background: Recently, there has been an emphasis on the use of interventions with biofeedback information for the maintenance or correction of posture. Objects: This study assessed the change of trunk posture and trunk muscle activation when people exhibiting postural kyphosis performed visual display terminal work with or without a contact feedback device (CFD). Methods: Eighteen right-handed individuals were recruited. Thoracic angle and right thoracic erector spinae (TES) muscle amplitude were analyzed. There were two sessions in these experiments. The control session involved 16 minutes of typing without a CFD, and the CFD session involved 16 minutes of typing with a CFD. The visual analog scale score was analyzed with a paired t-test, and the kinematic and electromyography data were analyzed through two-way repeated analysis of variance. Results: The paired t-tests revealed that subjects had significantly less pain after the CFD sessions than after the control sessions (p<.05). Significant main effects by session and by time were observed in the thoracic kyphosis angle (p<.05). There was a significant session${\times}$time interaction for TES amplitude (p<.05), along with significant main effects by session and by time (p<.05). Conclusion: The CFD caused people with postural kyphosis to straighten and to activate their TES continuously, even though they were habituated to bend their bodies forward. Therefore, the CFD was a beneficial treatment tool.

PURPOSE: This study was to investigate of pain and spine shape in elementary school students. The aim of this study was to prevent pain and spinal misalignment is to provide basic data and the need for regular screening for elementary school students. METHODS: This study had a survey research about pain and spine shape by using questionnaires and Formetric 4D. Subjects were 301 Elementary School Students RESULTS: In the presence or absence of pain and the presence of pain was in a high proportion and many of them indicated the back as a pain area, As a result of the spine shape contour, pelvic tilt was normal and trunk inclination was asymmetric as well as thoracic kyphosis and lumbar lordosis were diminished. There was a significant difference in relationship of trunk inclination according to pain CONCLUSION: The asymmetric of trunk inclination influenced the pain, In contrast, the pain did not influence thoracic kyphosis and lumbar lordosis in diminished. but, the diminution in thoracic kyphosis and lumbar lordosis are potential sources of pain. Regular checkups are necessary to prevent elementary school students from a change of spine shape and a pain, Moreover, education of maintaining normal posture should be followed.

The purpose of this study was to investigate the changes in the flexicurve kyphosis index (KI), the flexicurve lordosis index (LI) and the distance from the inferior angle of the scapula to the nearest vertebral spinous process (DS), as a dependent variable of scapular protraction, after applying of adolescents with thoracic hyperkyphosis using three different garments. A repeated measures design was used. Ten adolescents ($15.8{\pm}1.0$ years) with thoracic hyperkyphosis ($40.1{\pm}3.7$ Cobb angle) were recruited from a university hospital. A flexicurve ruler was used to measure KI and LI and a scoliometer was used to measure DS under three different conditions: wearing-a hospital garment (HG), wearing-a sham garment (SG), and wearing-an experimental garment (EG). KI under EG condition was significantly decreased compared with that wearing the HG. However, there was no significant difference between wearing the SG and HG. LI when wearing the EG was significantly increased compared with that when wearing HG. However, there was no significant difference under SG and HG conditions. DS when wearing the EG was significantly decreased compared with wearing HG. However, there was no significant difference between the SG and HG. The results of this study show that the EG was effective in decreasing KI, but not effective in decreasing LI. Hence, the effect of the EG for correcting sagittal spine angle in adolescents with thoracic hyperkyphosis is still debatable. However, since we showed that DS decreases in the EG, this method could be applied in correcting the scapular protraction.

Purpose: Flexed posture commonly increases with age in older women and is characterized by an excessive curvature in the thoracic spine (kyphosis), forward head posture, and decline in height. This study was conducted in order to determine the relationship between flexed posture, physical performance, and psychosocial factors in community dwelling elderly women in Korea. Methods: Fifty-two subjects with thoracic kyphosis of $40^{\circ}C$ or greater participated in this study. Flexed posture was measured using kyphosis angle (KA), forward head posture (FHP), and round shoulder (RS), and physical performance was evaluated using the short physical performance battery (SPPB), grip strength, and static and dynamic balance. Psychosocial factors were measured using depression and the quality of life (QOL). All data were analyzed using SPSS 18.0 software for windows. Results: KA showed significant correlation with SPPB score (r=-0.447) and dynamic balance (r=0.426) (p<0.05) depression (r=0.405) and QOL (r=-0.464) but not with grip strength and static balance in elderly individuals. FHP and RS showed significant correlation with SPPB score (r=0.002, r=-0341) and dynamic balance (r=-0.278, r=0.346) (p<0.05) but not with psychosocial factors. Conclusion: These findings suggest that flexed posture provides meaningful information about physical performance and psychosocial factors in elderly women. Our data suggest that the flexed posture may need to be addressed as part of the health management process for elderly women.
