Purpose: This study examined the effects of trunk side shift exercise on the Cobb's angle. Methods: Fifty-eight subjects (control group=30, scoliosis group=28) were enrolled in this study. The idiopathic scoliosis groups were divided randomly into two groups, a side shift exercise (SSE) group, and a trunk stabilization exercise (TSE) group. The SSE group performed side shift exercise on the developed chair training for eight weeks. The TSE group performed trunk stabilization exercise. A oneway ANOVA test was carried out to compare the results within the idiopathic scoliosis patient group before and after the exercises based on the different exercise methods. Results: The Cobb's angles were compared among control group and SSE group and TSE group. As a result, there was a significant difference from SSE group and TSE group(p=0.000), but there were no significant differences between the SSE and TSE groups (p=0.085). Conclusion: Side shift exercises are effective in improving the Cobb's angle. Therefore, the use of the side shift exercise chair designed in this study can replace general exercise either at work or during studies. Therefore, this method is easily accessible for busy modern students who are exposed to scoliosis or spinal disorders due to a pattern of inactivity.

Purpose: This study examined the effects of the application of Schroth exercise-based instrument Pilates exercise on the Cobb's angle, angle of trunk rotation, and low back pain of female patients with idiopathic scoliosis. Methods: Three patients with idiopathic scoliosis at a Cobb's angle of 20° or more participated in this study. Among the single-subject experimental research designs, a reversal (ABA) design was performed. In particular, Schroth exercise-based instrument, Pilates exercise, was performed for 10 weeks, consisting of five weeks between the baseline and intervention one period and five weeks between the intervention 1 and intervention 2 periods, and then followed up for five weeks. Results: After the Schroth exercise-based instrument, Pilates exercise, was applied, the Cobb's angle and the angle of trunk rotation decreased compared to the baseline in all subjects, and the follow-up period also showed a continuous decline. After Pilates exercise was performed, low back pain in subjects 1 and 2 was decreased in the intervention 1 period compared to the baseline. The level of low back pain in the intervention 2 period increased compared to the intervention 1 period, but a reduction was noted in the follow-up period. The low back pain in the subject was decreased in all intervention periods and the follow-up period. Conclusion: Schroth exercise-based Pilates exercise improves the Cobb's angle and the angle of trunk rotation for female patients with idiopathic scoliosis in their teens and 20s, and an effective intervention method is proposed for low back pain.

Objective: Adolescent idiopathic scoliosis patients make up 40% of all scoliosis patients, and it is likely to increase even more because of the increase in sitting times due to the pandemic. Method: The subject of this study was a 16-year-old female student. The Cobb's Angle at initial value was 42° at the thoracic and 33° at the lumbar. The subject's height was 161.6 cm, and the type of scoliosis was 3CL. The brace was built with fabric materials with the size information from the X-ray information and actual measurements. The brace was made for the adolescents to wear for a longer time by making them put pressure on the same pressure points of the existing braces. The subjects were required to wear the device for 16 hours every day for three months. Additional features to check the pressure and time were synchronized through an app for easier communication and management with the responsible investigator. Results: After wearing the 3D Fabric brace, Cobb's angle changed from 42° to 33° at the thoracic and 33° to 23° at the lumbar. The ATR changed from 9° to 8° at the thoracic and 11° to 6° at the lumbar. As a result, the changes in the ATR angle do relate to the decrease of Cobb's angle, which made the angle of scoliosis that is bent in a three-dimensional way improve, making the height of the subject increase from 161.6 cm to 163.5 cm. Conclusion: Through this study, developing a brace that is made in the form of the 3CL to align the strap direction and putting pressure on the proper pressure points makes Cobb's angle and the ATR smaller. This means that there is a positive effect on the changes in height. A brace made of light fabric material is a good brace to help treat adolescent idiopathic scoliosis. There was an opinion that it is more comfortable to wear than existing braces, but it seems necessary to conduct a quantitative study about the before and after of wearing the brace and a survey for Korean specific cases.

Objectives : The objective of this study was to observe the positive effects of acupuncture and bee-venom acupuncture treatment on lumbar hypolordosis. Methods : Acupuncture and bee-venom acupuncture were performed twice a week for 30 days to treat patients with low back pain patients showing a Cobb's angle [L1-S1] of less than $35^{\circ}$(treatment group=20, control group=13). Lumbar lordosis(Cobb's angle [L1-S1], Centroid angle [L1-S1]) was measured using an L-spine Lat. X-ray before and after treatment. Pain scales(VAS scale, ODI) were also was measured before and after treatment. SPSS 12K for Windows was used for statistical analysis of the results. Results : 1. VAS and ODI decreased significantly in the treatment group. 2. Lumbar lordosis, presented by Cobb's angle, increased significantly from $25.00{\pm}7.06^{\circ}$ to $30.95{\pm}10.02^{\circ}$ (p = 0.006). The increase of Cobb's angle in the treatment group $5.95{\pm}8.60^{\circ}$, and that of the control group was $-3.08{\pm}8.41^{\circ}$(p = 0.006). The increase of the Centroid angle of the treatment group was $3.85{\pm}8.83^{\circ}$, and that of the control group was $-2.92{\pm}7.63^{\circ}$(p=0.031). 3. Cobb's angle and Vas scale showed a significant correlation coefficient of -0.250(p=0.043). Increase of Cobb's angle and decrease of Vas scale showed a significant correlation coefficient of 0.420(p=0.015). Conclusions : Acupuncture and bee-venom acupuncture were verified to have a positive effect on pain alleviation of lumbar lordosis decreased patients while also affecting lumbar lordosis to be increased as a result of structural changes. It was also shown that lumbar hypolordosis has significant correlation with pain.

Objective: The Back Mapper is one type of Rasterstereography and it can be used in the clinic without radiation exposure. The purpose of our study was to prove the reliability and validity of the Back Mapper and to compare it with the Spinal Mouse, which is an assessment tool for spinal curvatures using a wheeled mouse, and the Cobb angle by X-ray. Design: Cross-sectional study. Methods: Twenty healthy adults participated in the test to investigate for the inter-rater reliability, intra-rater reliability, and concurrent validity. The tests were performed with assessment devices for scoliosis such as the Back Mapper, Spinal Mouse and Cobb's angle. Data was analyzed by an intraclass correlation coefficient (ICC) value and a standard error of measurement for reliability and correlation analysis for validity. Results: Intra-rater reliability of the Back Mapper was good (Cronbach's ${\alpha}$=0.821-0.984, ICC=0.696-0.969) except for assessing the lordotic angle. Inter-rater reliability was good (Cronbach's ${\alpha}$=0.870-0.958, ICC=0.770-0.919) in assessment for trunk imbalance, rotation of scapulae, thoracic angle, lumbar angle, and kyphotic angle. The kyphotic angle in the Spinal Mouse had a significant correlation icompared with the Back Mapper (r=0.510, p<0.05), and the Cobb's angle from an X-ray had a significant correlation with trunk inclination (r=0.532, p<0.05). Conclusions: These findings provide good intra-reliability of the Back Mapper in healthy subjects, but the Back Mapper requires more experienced practice to have good inter-reliability. Also, the variables of the Back Mapper does not seem as appropriate compared with the Cobb angle by X-ray.

Objectives : The purpose of this study was to investigate the correlation between lumbar lordotic angle and the power of trunk flexors, extensors in normal adults Methods : 34 normal participants participated in this study. Their lumbar lordotic angle(L1-S1 Cobb's angle and L1-L5 cobb's angle) was measured by x-ray taken on lateral direction, erect cross-arm position. And muscle power of trunk flexors and extensors of each participant measured using Cybex HUMAC NORM. Results : 1. The average of L1-S1 Cobb's angle was $47.21{\pm}8.88^{\circ}$ and the average of L1-L5 Cobb's angle was $36.32{\pm}9.62^{\circ}$(Table IV). 2. The average ratio of trunk flexors/extensors was $6.44{\pm}19.31%$(Table V). The average power of the trunk flexors was $165.18{\pm}55.05$(Newton-Meter/kg), and the power of trunk extensors was $257.18{\pm}85.53$ (Newton-Meter/kg)(Table VI). 3. Lumbar lordotic angle has no relation to the ratio of trunk flexors/extensors(Table VII, Fig. 4). 4. Lumbar lordotic angle has no relation to both the power of the trunk flexors and extensors(Table VIII, Fig. 5, Fig. 6). Conclusions : These results suggest that the lumbar lordotic angle measured by radiograph could not evaluate the power and ratio of trunk flexors, extensors.

Background: The purpose of this study is to find out the effect on the improvement in idiopathic scoliosis when applying the orthopedic manual physical therapy and myofascial release technique. Methods: 20 patients in Cheon-An ${\bigcirc}{\bigcirc}$ hospital were selected as subjects whose Cobb's angle were higher than $10^{\circ}$ according to the radiograph. They were treated for 60 minutes a day, three days a week, and 8 weeks so that the total time of visit would be 24. We performed five tests (Moire test, X-ray, standing height test, Cobb's angle, pelvic level test, VAS) to indentifiy the therapeutic effects. Results: Four test results were improved more remarkably after those treatment than before(p<.001), except pelvic level test (p>.001). Conclusion: we confirmed that there were correcting effects on most of the valuation index from the primary analysis, which divided the subjects into 2 groups by Cobb's angle, but there were more effective in patients having lower than $25^{\circ}$. There were similarly correcting effects on most of the valuation index according to the secondary analysis, but there were particularly more effective in children.

Objectives This study was conducted to characterize scoliosis patients visiting Korean medicine hospital and to analyze the demands and factors affecting discomfort. Methods This retrospective study analyzed 33 scoliosis patients who visited Korean medicine hospital from March, 2021 to October, 2021. The data analysis consisted of three factors: (1) demographic characteristics, (2) characteristics of demands on Korean medicine (reasons for choosing Korean medical treatment, preferred treatment methods, most uncomfortable part, treatment priorities) and (3) discomfort factors (treatment experiences, diagnosed age and Cobb's angle). Statistical analyses were performed and a p-value≤0.05 was considered to be statistically significant. Results 43.75% of the patients chose 'effectiveness' for the reason why they preferred Korean medicine treatment. 'Chuna treatment' was the most preferred treatment method. The patients chose 'lower back' for the most uncomfortable part and 'pain' for the highest priority of improvement. The Cobb's angle of included patients was 16.02±7.65° and it is not much differ to average of Cobb's angle in Korean. Discomfort was more severe in the patients with treatment-experienced than treatment-naive. The score of discomfort in appearance and psychological were higher in the patients diagnosed in childhood or adolescent period than who were diagnosed after adult. Classification based on Cobb's angle showed no statistical difference. Conclusions Not only Cobb's angle but also other clinical factors should be considered for effective treatment in scoliosis. Also, It is necessary to pay attention to adult scoliosis patients.
