Objective: The purpose of this study was to investigate the effect of 3-dimensional posture correction(3DPC) exercise program incorporating PNF respiratory muscle strengthening(RMS) exercise on spinal alignment and trunk expansion in patients with idiopathic scoliosis and the difference in intervention effect by type of idiopathic scoliosis. Design: Comparative study using paired t-test and analysis of variance measures. Methods: The subjects of this study were 5 men and 24 women diagnosed with idiopathic scoliosis with a Cobb angle greater than 10 degrees and less than 45 degrees. A 3DPC exercise program incorporating PNF RMS exercise was conducted twice a week for 1 hour per session for 6 weeks, and Cobb angle, Angle of trunk rotation, and trunk expansion were measured before and after the intervention. Results: After the intervention, Cobb angle and trunk rotation angle showed a statistically significant decrease, and trunk expansion showed a statistically significant increase. In the effect difference by type, there was a statistically significant difference in the angle of trunk rotation of the thoracic in 3C and Single Lumbar. Conclusions: In conclusion, it is thought that a 3DPC exercise program incorporating PNF RMS exercise can be effectively used in clinical practice to improve spinal alignment and trunk expansion in patients with idiopathic scoliosis.

According to recent data more than 80% of people suffer from back pain, due to an aging and a poor posture, at least once in their life time, and 7~10% of them have chronic spine illness. Researchers over the years have studied on various spinal traction devices that utilize the force of traction, and have also reported clinical test results. However, most existing devices are too complicated and too expensive. In order to solve these problems, we have developed a new device in which the frame moves up and down and at the same time tilting angle of the frame is adjusted. We have analyzed the forces applied on the body as a function of tilting angle. And the result shows that the new device has achieved the force of traction, which is known to be effective for spinal rehabilitation.

PURPOSE: This study assessed the exercise programs for improving the spinal angle and trunk flexibility by applying the aquatic exercise and sling exercise to young adults with scoliosis. METHODS: The subjects were 14 participants diagnosed with scoliosis. They were assigned randomly either to an aquatic exercise group (n=7) that received the WATSU exercise program or to a sling exercise group (n=7) that received a sling exercise program. The exercise program was 50 minutes once, three times a week, 12 times for four weeks. The spinal angle and flexibility were measured using the Cobb's angle and modified sit and reach test, respectively. Two variables were analyzed before and after the intervention, and the aquatic exercise group and sling exercise group were compared. RESULTS: After the intervention, the Cobb's angle decreased significantly, and the flexibility increased significantly in both groups (p<.05). A larger increase in flexibility was observed in the aquatic exercise group than in the sling exercise group (p<.05). CONCLUSION: These results showed that the two exercise programs improved the spine angle and flexibility. The increased flexibility showed that aquatic exercise was more effective than the sling exercise. Therefore, aquatic exercise and sling exercise can be used in the treatment and prevention of scoliosis.

The purpose of this study is to investigate how the application of a Thorax belt affects the stability of the spine in subjects with a wide infra-sternal angle. A total of 15 subject with wide infra-sternal angle participated in the experiment. Active Double leg lowering and active one-leg raising were performed with or without a thorax belt. Two spinal stability tests (active double lowering and active one-leg raising) performed with or without thorax belt application showed significant differences between each condition. Based on the results of present study, the application of a thorax belt is considered to be an effective therapeutic tool that can stabilize the spine to subjects with abnormally increased chest cage and spinal or trunk instability.

The aim of this study was to identify the characteristics of the flexion withdrawal reflex modulated by the hip angle and hip movement in spinal cord injury (SCI). The influence of the hip position and passive movement were tested in 6 subjects with chronic SCI. Each subject placed in a supine position and lower leg was fixed with the knee at 5 -45 degree flexion and the ankle at 25-40 degree plantar flexion. A train of 10 stimulus pulses were applied at 200 Hz to the skin of the medial arch to trigger flexion reflexes. From results of the regression analysis, static properties of normalized muscle activation of flexor muscles have the linear relationship with respect to hip angle (P< 0.05). In order to verify the neural contribution of flexion reflex, we compared the static and dynamic gains of estimated muscle activations with measured EMG of ankle flexor muscle. Form this study, we postulate that the torque and muscle response of flexion withdrawal reflex have linear relationship with hip angle and angular velocity.

The Study In order to obtain images of overlap of the two iron cores in the spinal cord simple x-ray scan after surgery of patients with ulcer lateral sclerosis and a fractured backbone, the researcher conducted a subjective evaluation on five radiographers of the university hospital's imaging department for more than 10 years. The results of the experiment showed that the lateral shot of lateral scoliosis of the spinal cord was taken with the middle face of the IR plane, and then the X-ray tube angle was taken vertically with the vertical spinal column fan-tom position, resulting in two overlapping images and high scores in the subjective evaluation. In addition, lateral shots of the lumbar dislocation fractured lumbar vertebrae were taken with the forehead aligned with the center of the IR plane and then with the X-ray angle perpendicular to the fourth waistline and the angle of the spinal cord perpendicular to the fourth waistline, the image of the two iron cores could be obtained from the radiographer.

Purpose: Continuous use of a smartphone increases the angle of forward bending of the user's cervical vertebrae, causing pain in the shoulders and back, including the thorax, lumbar region, and vertebrae. Although there are many studies on changes in the cervical spine due to smartphone usage, the changes in the shoulders, thoracolumbar spine, and pelvic have rarely been compared. The purpose of this study is to investigate the change in the spinal segments, shoulders, and pelvic when using a smartphone with both hands while in the standing position. Methods: This study was conducted on 35 adults in their twenties. The selection criteria for the subjects were limited to those in a similar age group, thus excluding posture differences according to age, and to those who did not have specific diseases or pain in the spinal and musculoskeletal system for 12 months prior to the study. In this study, we used a 3D spinal diagnostic imaging system (Back Mapper, Frickenhausen) to compare the changing conditions in each vertebral segment before and during smartphone usage with both hands while in the standing position. Posture differences according to smartphone usage were compared using the paired t-test for the motion of each spinal segment. Results: This study showed that the thoracic and lumbar angle increased posteriorly during smartphone usage (p<0.05). In addition, the anterior rotation angle of the shoulder bone significantly increased, but no significant difference occurred in the pelvic region. Conclusion: Based on the results of this study, smartphone usage with both hands while in the standing position showed that the spine, as a whole, forms a kyphotic curve. Therefore, we propose to present a postural guideline for correct smartphone usage, considering the change in each vertebral segment.
