Purpose: This study was undertaken to identify the effects of apparatus Pilates exercise on Cobb's angle, angle of trunk rotation, and depression in female patients with idiopathic scoliosis. Methods: Participants included five patients with idiopathic scoliosis presenting with Cobb's angle of 10 degrees or more. Among the single-subject experimental research designs, the reversal (ABA) design was selected and performed. The apparatus Pilates exercise was performed for a total of 16 weeks, comprising 8 weeks between the baseline and intervention 1 period and 8 weeks between intervention 1 and intervention 2 periods. The patients were then followed up for 5 weeks. Results: In all subjects, compared to the baseline, Cobb's angle and the angle of trunk rotation decreased after application of the apparatus Pilates exercise. The follow-up period also showed a similar continuous decline. Following the apparatus Pilates exercise, the depression scale in subject 3 was increased during the intervention 1 period as compared to the baseline. However, the patient displayed a reduced depression scale in intervention 2 and follow-up periods. The depression scale in all other subjects was decreased for both intervention periods and the follow-up period. Conclusion: The application of apparatus Pilates exercise improves Cobb's angle and the angle of trunk rotation for female patients with idiopathic scoliosis in their 10s and 20s. Our results also indicate that this is potentially an effective intervention method to overcome depression.

The purpose of this study was to determine the effect of trunk posture on muscle activity and motion of scapular and scapulohumeral rhythm. Thirty-one healthy subjects performed right-arm abduction and adduction along the frontal plane while standing in both upright and flexed posture of trunk. Scapular upward rotation, anterior tilting and internal rotation ware recorded using a motion analysis system and muscle activity of upper trapezius, lower trapezius and serratus anterior ware recorded using surface electromyography during abduction and adduction in both trunk postures. then, scapulohumeral rhythm was calculated. Scapulohumeral rhythm and scapular posterior tilting in flexed posture was significantly decreased than in upright posture. Also, muscle activity of lower trapezius in flexed posture was significantly increased and serratus anterior was significantly decreased than in general posture. The result of this study revealed that flexed posture of trunk altered the muscle activity and kinematic of scapular. Measurement of trunk posture should be included the evaluation of dysfunction and disorder of shoulder girdle since rehabilitation of trunk posture is important to restore of upper limbs function.

Purpose: The transverse abdominis and themultifidus muscle are located in the core. They surround one's trunk and help in body stabilization. Specifically, they control spine articulation to maintain posture and balance. Therefore, weakened deep muscle in the trunk may cause spinal malalignment. This study aims to compare the correlation between the thickness of the transverse abdominis and the multifidus muscle and the spine alignment among college students in their 20s. Methods: This study measured the thickness of the transverse abdominis and the multifidus muscle of 42 healthy college students in their 20s using ultrasonic waves. The thickness of the muscle was measured for the length of the cross-section except for fascia. The thickness of the left and right muscles was measured, and the mean value was calculated. As the thickness of the transverse abdominis can increase because of pressure during exhalation, it was measured at the last moment of exhalation. Spinal alignment was measured by the kyphosis angle, lordosis angle, pelvic tilt, trunk inclination, lateral deviation, trunk imbalance, and surface rotation using Formetric III, which is a three-dimensional imaging equipment. They were measured for three times, and the mean values were calculated. The general characteristics of the subjects were analyzed using descriptive statistics. The correlations between each factor were analyzed using Pearson's correlation analysis. Results: The transverse abdominis showed asignificant correlation with trunk inclination (p<.05). The multifidus muscle showed a significant positive correlation with pelvic tilt and a negative correlation with surface rotation (p<.05). Conclusion: The thickness of transverse abdominis and the multifidus muscle appears to influence spinal alignment. Specifically, the multifidus muscle, which plays an important role on the sagittal plane, influences surface rotation, thus making it an important muscle for scoliosis patients. Therefore, a strengthening training program for the transverse abdominis and the multifidus muscle is necessary according to specific purposes among adults with spinal malalignment.

Purpose: This study aims to verify the effects of Pilates exercise using the three-dimensional (3D) Schroth breathing technique on scoliosis patients in comparison with the existing Pilates exercise technique, which uses lateral breathing. Methods: The subjects were 16 scoliosis patients who went to S fitness center in Daegu, Korea. They were randomly and equally divided into a Schroth Pilates exercise group (SPEG), who performed Pilates exercise using 3D Schroth breathing, and a Pilates exercise group (PEG) who performed Pilates exercise using lateral breathing. The subjects conducted the Pilates exercise three times per week for 12 weeks. Changes in their Cobb's angle, angle of trunk rotation, and chest expansion ability were measured before and after the exercise. Results: Both groups experienced significant improvement in their Cobb's angle, angle of trunk rotation, and chest expansion ability after the exercise (p<0.05). Between-group comparison after the exercise showed that SPEG's improvement in Cobb's angle, angle of trunk rotation, and chest expansion ability were more significant than those of the PEG (p<0.05). Conclusion: This study verified that Pilates exercise using 3D Schroth breathing was more effective in improving scoliosis patients'physical condition than existing Pilates exercise. The researcher anticipates that the 3D Schroth breathing technique will be effectively utilized in other diverse intervention exercises besides Pilates exercise.

Objective: The purpose of this study was to investigate the effect of mobile phone text messaging on the collision avoidance strategy for an approaching and stationary pedestrian. Method: Eighteen healthy young adults participated in this study. Each participant was asked to perform a task to walking with/without mobile phone text messaging and a task to avoid collisions with another pedestrian who was approaching or stationary during walking. Results: When text messaging with avoidance collision, it showed an early onset time, a larger mediolateral COM trajectory, trunk rotation angle and trunk rotation velocity (p<.05). Also, compared to an approaching pedestrian, when avoiding collision with a stationary pedestrian, it showed a later onset time, a lager avoidance displacement, mediolateral COM trajectory, trunk rotation angle (p<.05). Conclusion: Results suggest that mobile phone text messaging while collision avoidance leads to delay the perception stage and alters the adaptation stage. Consequently, pedestrian executed in an exaggerated avoidance action to create a greater safety margin when attending to mobile phone test messages while avoiding another pedestrian.

Purpose: Most studies have reported that the abdominal muscle thickness differs according to gender but none of these studies reported a gender difference in the thickness of the multifidus and erector spine. The spinal alignment is affected by the left and right balance in the trunk muscle. The aim of this study was to identify the trunk muscle symmetry according to gender and the correlations of the trunk muscle thickness with spinal alignment. Methods: Forty three subjects(27 males and 16 females) were enrolled in this study. The trunk muscle thickness was measured by ultrasonography. The trunk muscle, which consisted of the rectus abdominis (RA), external oblique abdominis (EOA), internal oblique abdominis (IOA), transverse abdominis (TrA), erector spine (ES), and multifidus (MF), was measured. The spinal alignment was measured by Formetric-III 3D analysis. The dependent variables of the spinal alignment were the trunk imbalance, trunk inclination, lateral deviation, and surface rotation. Results: The muscle thickness of the EOA muscle increased more significantly in the right side than the left side (p<0.05). Each left and right difference in the muscle thickness between the male and female group showed a significant difference (p<0.05) except for the TrA thickness. Significant positive correlations were observed between the ES and lateral deviation and between the TrA with trunk imbalance. Conclusion: These results suggest that asymptomatic men have a greater trunk muscle thickness than women but there was no difference between the left and right in healthy adults. The trunk muscle thickness of ES, TrA is related by the spinal alignment.

Objective: To investigate rotation movement of segment for performing each position and its effect on knee/hip angulation, COM inclination, and edging angle changes. Method: Twelve Alpine skiers (age: $25.8{\pm}4.8years$, height: $173.8{\pm}5.9cm$, weight: $71.4{\pm}7.4kg$, length of career: $9.9{\pm}4.6years$) participated in this study. Each skier was asked to perform counter-rotation, neutral, and rotation positions. Results: Shank and thigh were less rotated in the counter-rotation position than in other positions, whereas the trunk and pelvis were more counter-rotated (p<.05). Hip angulation, COM inclination, and edging angle were significantly greater in the counter-rotation position than in other positions (p<.05). Conclusion: Our finding proved that the counter-rotation position increases hip angulation, COM inclination, and edging angle. Consequently, we suggest that skiers should perform counter-rotation of the trunk and pelvis relative to the ski direction in the vertical axis for the counter-rotation position. Further analysis will continue to investigate the effects of the counter-rotation position in real ski slope with kinetic analysis.

This study wan described the movement patterns when rising from supine to erect stance in the third through eighth decades. Two hundred fifty six subjects, ranging in age from 30 year to 89 were filmed while rising from a supine position. Movement patterns were classified using categorical descriptions of the action of the upper and lower extremity, head-trunk region. This study was designed to determine whether within the rising task the movement patterns of different regions of the body vary with age level and sex, to describe time by subjects to perform this task. The incidence of each movement pattern was calculated and graphed wi th respect to age level and sex. Erect standing time was increased by age increasing in beth sex group. The most common form of rising for subject in the third through fifth decades both sex usually involved symmeytrical push with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern wi th head-trunk and symmetrical push to push and reach pattern with upper extremity, symmetri cal squat pattern with lower extremity. partial rotation with head-trunk. In the sixth through eighth decades usually involved symmetrical push to push and reach pattern with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern with head-trunk in both sex group.
