The purpose of this study were to examine the effect of two different pelvic alignments and the back belt on electromyographic(EMG) activity of the erector spinae during lifting. The results were as follows: 1) EMG activity of erector spinae was greater when the pelvis was tilted anteriorly than when the pelvis was tilted posteriorly during lifting. 2) EMG activity of erector spinae was greater when the back belt than when without the back belt during lifting. These results suggest that the greater EMG activity of erector spinae with an anterior pelvic tilt position and with back belt during lifting may ensure optimal muscular support for the spine while handling loads.

This study purpose is to know about the effect of Cobb's angle of scoliosis patient by Pilates ecercise. It was executed for prove this exercise with Pilates Postural Correct Exercise(PCE), Spine Stretching Exercis(SSE), Muscle Strengthing Exercise(MSE). PCE is useful for unbalanced muscle energy and SSE gives relax for hypertensioned muscles and MSE is correcting balance for prime mover and secondary mover and so it will be recovery for elasticity and flexibility of paraspine muscles. The method study was proved with a Cobb's angle measurement of Lumbar spine by X-ray test before and after. As a result for the test, Cobb's angle by X-ray it shows reduced about 5 degree in statistics(p=0.005). And so It shows the Pilates exercise gives reduce for Scoliosis.

This study examined how the eight-week spinal stabilization exercise program affects the cervical disability index, postural balance ability, and body shape change. The exercise program performed 60 minutes of spinal stabilization exercise three times a week for eight weeks. Sixteen patients with chronic neck pain, who complained of neck pain for six months, were classified into exercise group (n=8 patients) and control group (n=8 patients). The results before and after the eight-week exercise program were observed. Significant differences were observed in the time, group, and interaction of the neck disability index (p<.05). The balance ability showed significant interaction effects between the groups and periods (p<.05). Significant differences were noted in the timing and interaction in the pelvic inclination angle in posture change (p<.05), and there were significant differences in the group, timing, group, and interaction in the cervical and shoulder position angles (p<.05). The above results showed that the spinal stabilization exercise significantly improved the cervical disability index, balance ability change, and body shape change in patients with chronic neck pain. Future studies will analyze the specific changes in spinal structure through radiographic imaging to increase the validity of spinal stabilization exercise.

The purpose of this study was to determine the effectiveness of the pelvic compression belt on the thickness of the erector spinae and multifidus during hip extension on quadruped position. Thirty male university students volunteered to participate in this study. The pelvic compression belt was positioned below the anterior superior iliac spines with the stabilizing pressure using elastic compression bands. Subjects were instructed to perform hip extension in quadruped position with and without applying the pelvic compression belt. The thickness of the erector spinae and multifidus was measured ultrasound during prone position, quadruped position without applying pelvic compression belt and quadruped position applying pelvic compression belt. Data were analyzed using repeated ANOVA. Muscle thickness of multifidus was significantly higher applying the pelvic compression belt than without applying the pelvic compression belt (p<.05). Muscle thickness of elector spinae was significantly higher applying the pelvic compression belt than without applying the pelvic compression belt (p<.05). Therefore, the research can contribute to the prescription and application of quadruped position exercises in clinical practices.

The purpose of this study was to investigate the effect of cross arms and palms facing forward on spinopelvic parameters during the whole spine lateral radiography. In addition, we would like to present the usefulness of a posture with the palm facing forward during whole spine lateral radiography of the spine using EOS. The subjects of this study were images of a total of 50 patients (18 males, 32 females) who whole spine lateral radiography using the conventional method and the EOS method from October 2020 to March 2021. The posture used in this study was set as 'CAP' for cross arms and 'PUSH' for posture with palms facing forward. In this study, among the spinal stability factors, thoracic kyphosis (thoracic vertebrae 4 to 12), lumbar lordosis (lumbar vertebrae 1 to sacrum 1), sagittal vertical axis, sacral slope, and shoulder flexion angle were compared on average. The mean thoracic kyphosis was 34.52±12.46° for CAP and 28.46±10.81° for PUSH (p<0.01). The lumbar lordosis of CAP was 42.45±17.45°and that of PUSH was 40.56±16.14°(p>0.57). The sagittal vertical axis was 26.59±34.34 mm in CAP and 21.21±35.41 mm in PUSH (p>0.44). In CAP, the sacral slope was 30.96±10.29°, and in PUSH, it was 31.01±10.19° (p>0.98). shoulder flexion angle was 38.31±8.24° for CAP and 26,08±6.71° for PUSH(p<0.01). As a result of this study, the PUSH posture is considered to be a posture that can minimize the shoulder flexion angle and can perform a stable examination while minimizing changes in spino-pelvic parameter.

The purpose of this study lies in examining how sling lumbar stabilization exercise affects static standing balance of adolescent idiopathic scoliosis patients. The subjects were forty patients who were diagnosed with idiopathic scoliosis. They were randomly assigned either to a experimental group (n=20) that received sling lmubar stabilization exercise program or to a control group (n=20) that received only education. Data were obtained for each patient from total sway path and sway velocity in standing on both feet with eyes closed and standing on both feet with eyes open were measured, using balance performance monitor. All variables were measured at pre- and post-exercise. There were significantly differences between the both groups for all variables at post-exercise (p<.05). The experimental group showed a significantly decreases in all variables at pre- and post-exercise (p<.05). But the control group showed a no significantly differences. These results revealed that sling lumbar stabilization exercise improved static standing balance, by reducing COP(center of pressure) sway path and sway velocity of idiopathic scoliosis patients, and it is expected that sling lumbar stabilization exercise will be used as balance enhancement exercise intervention for the treatment of adolescent idiopathic scoliosis patients.

Recently Recently, the incidence of spinal diseases due to poor posture among students and office workers is increasing, and various studies have been conducted to help maintain correct posture. In previous studies, a membrane sensor or a pressure sensor was placed on the seat cushion to see the weight bias, or a sensor that restrained the user was attached to measure the position change. In our previous study, we developed a sensor device which can be easily attached to the body with an adhesive gel sheet and that measures and outputs the user's posture and body position in real time, but it has a limitation in the accuracy of the sensor value. In this study, a study was conducted to improve the performance of the position conversion sensor device and quantitatively evaluate the accuracy of the angle conversion measurement value, and a high accuracy with 2.53% of error rate was confirmed. In future research, it is considered that additional research targeting actual users is needed by diversifying posture correction training contents with multimedia elements added.

The purpose of this study was to obtain data to support applied motions of bench press and to provide basic data for the efficient execution of the exercise by analyzing muscular activation through measuring electromyogram of pectoralis major and erector spinae when flat bench pressing with feet on the ground versus feet on the bench. For this study, 4 amateur bodybuilders and 2 health trainers were chosen as subjects. Surface electrodes were attached on the measuring muscles; pectoralis major and erector spinae. Motion phases were defined for the flat bench press and each subject, with a 10RM load, performed a set with feet on the ground and another set with feet on the bench. Data was analyzed in SPSS 20.0 and the following results were obtained. The placement of the feet did not affect the muscular activation of the pectoralis major during the flat bench press. however, the muscular activation of the erector spinae was different between the two positions.
