The aim of this study is to determine the effect of virtual reality(VR) exercise using XBOX $Kinect^{TM}$ on the scoliometer angle and muscle activities of the trunk. The subjects of the study were 13 young adults who devided into a virtual reality-based exercise group(VREG, n = 7) and a traditional stabilization exercise group(TSEG, n = 6). The VREG received virtual reality game for 5 days a weeks, 30 minutes a day, for a 2 weeks and the TSEG received general trunk stabilization exercise for the same period and frequency. The subjects were measured and compared for muscle activities of trunk stabilization before and after the program. VREG tend to decrease more than TSEG in scoliometer angle. In addition, VREG showed a significant decrease in muscle activities of multifidus. This study presents the impact of virtual reality-based exercise program on trunk balance and stabilization. The following studies need customized programs for subjects that trunk balance and stabilization is required.

Purpose: The purpose of this study will demonstrate that relationship between scoliosis and gait factor and foot weight bearing in ambulation. Methods: Subjects were 40 elementary students. A normal control group consisted of a total of 20 children without any known musculoskeletal disorders and an AIS group of 20 children with mild AIS (defined by a Cobb angle between 10 and $25^{\circ}$) were recruited. Measurements were scoliometer screening test, Cobb angle, gait parameter (rate of swing/stance phase, gait velosity), foot weight bearing (entire, fore, hind). Results: Scoliometer screening test (P = 0.000) and X-ray Cobb angle (P = 0.000) significant difference of group which was significantly higher in the AIS group. Gait parameter not showed significant difference. Forefoot weight bearing was significantly higher in the AIS group than more normal group. Conclusion: It seems that the results of weight bearing analysis in ambulation may be used in modifying rehabilitation programs for individual needs of patients with idiopathic scoliosis.

Scoliosis can be biomechanically described as a three dimensional deformity of the spine, with deviations from the physiologic curves in the sagittal and frontal planes, usually combined with intervertebral rotation. Various factors are suspected such as genetic defects, uneven growth of the vertebrae, hormonal effects, abnormal muscular activity, postural problems, or a mix of some of these elements, but its initial cause is known in only 15-20% cases. The screening test for diagnosing scoliosis is called the Adams Forward Bend Test. During the experiment, the subjects were asked to bend over, with arms dangling, until a curve could be observed. The Scoliometer was placed on the back of the subjects and used to measure the difference between the left and right apex of the curve in the thoracic, thoracolumbar and lumbar area. Then, the subjects were asked to perform Maximum Voluntary Contractions (MVCs) using the digital back muscle dynamometer in three different postures: (1) 0o (sagittally symmetric); (2) 30o from the mid-sagittal plane (clockwise); and (3) 30o from the mid-sagittal plane (counterclockwise). In addition to the experimental data, subject-dependent variables including Body Mass Index (BMI), percentage of body fat and muscle mass of left/right arms and legs were employed to reveal the cause of difference among three MVC conditions. All those variables were tested using statistical methods.

In the present study, we aimed to examine the effects of Schroth exercise(three-dimensional convergence exercise) on pulmonary function(vital capacity, and chest expansion), Cobb's angle, scoliometer angle, and erector spinae muscle activity. We examined 40 students with idiopathic scoliosis(Cobb's angle $10^{\circ}$). They were divided into the Schroth and conventional exercise groups, with 20 people in each group. Statistical analysis was performed by using SPSS 18.0 with a paired t-test(pre-post difference) and an independent t-test(between-group differnence). the result of were as follows; 1) After 8 weeks of Schroth exercise, significant improvements were observed in Cobb's angle, rib hump, vital capacity, chest expansion, and right thoracic longissimus muscle activity. 2) After 8 weeks of conventional exercise, a significant improvement was observed only in chest expansion. These findings indicate that the Schroth exercise program improved the Cobb's angle, rib hump, pulmonary function, and sEMG results. Therefore, this study demonstrates the usefulness of the Schroth exercise program for idiopathic scoliosis.

This study investigated the prevalence of scoliosis among undergraduate students who were in early adulthood, and to examine its relationship with body mass index (BMI), which has been associated with scoliosis in previous studies. A descriptive survey of 158 students of universities based in Seoul, Daejeon, Daegu, and Gyeonggi Province was conducted. A structured questionnaire comprising items pertaining to general features, postural features, and BMI was used, and the angle of the trunk rotation (ATR) was measured directly with a scoliometer to assess the spinal angle. Participants with an ATR of greater than $6^{\circ}$ were classified into the scoliosis group. Data were collected for three weeks from November 7, 2014. Scoliosis and BMI were analyzed for their frequencies and percentages, and their relationships were analyzed using the ${\chi}^2$-test and Logistic regression. Overall, 114 (72.2%) participants had an ATR of smaller than $5^{\circ}$, while 44 (27.8%) had an ATR of greater than $6^{\circ}$. After excluding the confounding variables, the overweight group was 2.63 times more likely than the normal BMI group to have an ATR of greater than $6^{\circ}$ which was statistically significant. However, the underweight group was 0.24 times less likely than the normal BMI group to have an ATR of greater than $6^{\circ}$, but this difference was not statistically significant. Although early examination and management of scoliosis in South Korea is generally performed on children and adolescents, the high prevalence of scoliosis among university students found in this study calls for aggressive early examination and management for this age group as well.

Objective : The purpose of this study was to introduce our surgical experiences of scoliosis and to evaluate the effectiveness of anterior correction and fusion in adolescent idiopathic scoliosis (AIS). Methods : Between August 2004 and August 2007, four patients with AIS were treated with anterior segmental fusion and fixation at our hospital. Mean follow-up period was 9 (6-12) months. The average age was 14.0 (13-15) years. According to Lenke classification, three patients showed Lenke 1 curve and one patient with Lenke 5 curve. Single rod instrumentation was performed in one patient, dual rod instrumentation in one patient and combined rod instrumentation in two patients. Coronal Cobb measurements were performed on all curves in thoracic, thoracolumbar and, lumbar spine and the angle of hump was measured by a scoliometer pre- and postoperatively. Results : The average operative time was 394 minutes (255-525) with an average intraoperative blood loss of 1,225 ml (1,000-1,700). The mean period of hospital stay was 19.3 days and there was no complication related to the surgery. The mean Cobb angle was reduced from $43.3^{\circ}$ to $14.8^{\circ}$ (65.8% correction) postoperatively and the rib hump corrected less than $5^{\circ}$. All patients and their parents were satisfied with the deformity correction. Conclusion : Anterior spinal correction and fusion of AIS with Lenke 1 and 5 curve showed excellent deformity correction without any complications. In particular, we recommend anterior dual rod instrumentation because of mechanical stability, better control of kyphosis, and a higher fusion rate.

Purpose: The purpose of this study was to investigate the influence of adolescent's scoliosis on the stress level and study-attitude, to inform the public that there exist an important correlation between adolescent's scoliosis and stress, as well as, study-attitude, using a questionnaire. Methods: For this study, questionnaires were distributed to elementary school in G city from May 10 through May 31, 2011. This study measured a primary scoliosis-test by a scoliometer with 300 elementary school students and a secondary test by Cobb's angle using an X-ray. The subjects were divided into 2 groups (normal group (n=20), scoliosis group (n=20)). The collected data were analyzed by a t-test and Pearson analysis. Results: As a result of this study, the Cobb's angle showed significant difference between the scoliosis group and the normal group (p<0.001). Also, it tended to have a greater stress level in the scoliosis group than the relationship between scoliosis and the stress or study-attitude compared to the normal group (p<0.05). The correlation of stress according to Cobb's angle showed a positive relationship (r=0.36), and the correlation of study-attitude to Cobb's angle showed a negative relationship (r=-0.04). Conclusion: In conclusion, this study showed that scoliosis affects stress and study-attitude. We hope that this result would help diagnose adolescent's scoliosis in anearly stage and prevent any phychologic and social problems relating to it.

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.

Objectives: The purpose of this study is to investigate the characteristics, validity, and reliability of non-radiological assessment tools of scoliosis that have been studied so far. Methods: Electronic databases including Pubmed, Cochrane Library, CNKI, Science On, RISS, OASIS were searched by keywords including 'scoliosis assessment', 'scoliosis screening', 'physical examination', 'functional measurement', 'photography', and 'smartphone'. Results: 32 articles using radiation-free assessments were identified from 1,011 records. The mostly used non-radiological methods were Surface topography, Scoliometer, Ultrasound, Digital Infrared Thermal Imaging, and Photography. The other methods were Gait analysis, 3D depth sensor imaging, and Low intensity electromagnetic scan. Conclusions: It was found that non-radiological assessment tools might reduce the number of radiographs taken in scoliosis patients. To increase the reliability and validity, further research on the measurement tools of scoliosis will be needed.
