Abstract ▼ AI-Helper

This study was conducted to identify how a flexi-bar exercise influences body alignment and balance in adults who have asymmetry in their right or left body. In total, 20 participants were separated into the experimental group and the comparison group. Those in the experimental group participated in a flexi-bar exercise for 6 weeks and based on the coronal plane before and after exercise, their body alignment and balance were measured behind the body. The result was those who had participated in a flexi-bar exercise significantly improved their angle of acromion on both sides, the difference in the angle and height of the posterior superior iliac spine on both sides(p<.05), and the balance of the center sagittal plane(p<.05). Through this study, it could be said that participating in a flexi-bar exercise would improve postural alignment and balance of the shoulder and pelvis in adults with asymmetric posture.

문제 정의

This study aimed to determine the effect of a flexi-bar exercise on postural alignment and balance improvements, and the following results were observed. The flexi-bar exercise was found to improve the difference in the acromion angle on both sides, the difference in the height and angle of PSIS on both sides, and the balance ability in the sagittal plane.
Few studies have been conducted on exercise using a flexi-bar. Thus, this study aimed to study the effects of a flexi-bar exercise on postural alignment and balance with adult subjects in their 20s who had asymmetric posture, thereby developing an effective exercise program for asymmetric posture improvement.
The exercise also affects metabolism activation and balance control due to muscle development, activation of the muscular system, and small oscillation(16, 17). Using the above advantages of the flexi-bar, this study aimed to determine the effects on postural alignment and balance improvements of asymmetric posture.

제안 방법

In this study, a standard bar was used. In this exercise method, the exercise program on the flexi-bar web site was newly configured so the subjects in the exercise group performed each exercise for 30s followed by a 30s rest, which comprised one set. Then, three sets were completed by each subject.
In this study, the postural alignment and balance of 20 subjects were measured using a GPS to diagnose their postural alignment prior to participating in a flexi-bar exercise program. All subjects were randomly divided into an exercise group of 10 subjects and a control group of 10 subjects.
The researcher moved an ideal plumb to position it on the midline of the subject to measure the data. The evaluation of the postural alignment was conducted twice: before and after the study and all data were analyzed using the GPS program.
Subjects stood on the area marked in the examination plate with two feet while staring forward. The examination method was as follows: subjects maintained open eyes during measuring of the coronal midpoint, midsagittal midpoint, and curve length of the COG for 1 min.
All subjects were randomly divided into an exercise group of 10 subjects and a control group of 10 subjects. The exercise group performed a flexi-bar (Togu/Germany) exercise for 40 min daily three times a week for six weeks while the control group maintained daily activities without exercise. Changes in postural alignment and balance improvements in all subjects were measured before and after the exercise.
Then, they stood on the assessment bar while looking forward with a relaxed posture. The researcher moved an ideal plumb to position it on the midline of the subject to measure the data. The evaluation of the postural alignment was conducted twice: before and after the study and all data were analyzed using the GPS program.

This study was conducted from April 9 to June 10, 2014 for six weeks with students at Y University in Gyeonggi-do. Those who had asymmetric posture behind the body based on the frontal plane were selected as subjects using a Global Postural System(GPS) before the experiment, and those with no other musculoskeletal problems, neurological disorders, or psychiatric problems were selected as 20 final subjects who consented to participate in this study.

데이터처리

The balance of the subjects was analyzed using 30135/PPpedana stabilometrica(Chinesports, Italy) and a software program called Podate Stabilometric. This equipment can assess balance ability by measuring the COG movements.
0 program for Windows. To compare changes in postural alignment and balance before and after the exercise, a paired t-test was conducted, while an independent t-test was used to compare the difference between the study groups. All statistical significances were analyzed at a level of α=.

성능/효과

The result showed a reduction in the Cobb's angle and significant flexibility improvements, while the height of PSIS on both sides was the same before(±4.43) and after the exercise(±4.71) after 12 weeks without significant changes(22).
The result showed that while opening their eyes, the COG of the exercise group was improved from -12.48±4.79 to -1.34±1.87 in the sagittal plane, indicating a significant movement of the COG to the midpoint(p<.05).
The flexi-bar exercise was found to improve the difference in the acromion angle on both sides, the difference in the height and angle of PSIS on both sides, and the balance ability in the sagittal plane. This study verified that the flexi-bar exercise improved the postural alignment and balance ability of those with asymmetric posture.
