Purpose: Spinal instability due to weakness of abdominal muscles is one of the major causes that induces low back pain (LBP). The purpose of this study was to investigate any differences in abdominal muscle activity during curl up, roll out, and jack knife exercises using a swiss-ball or sling. Methods: Twenty healthy subjects were randomly assigned into either a swiss-ball exercise group (SBEG) or a sling exercise group (SEG). Subjects performed curl up, roll out and jack knife exercises using the swiss ball or sling. Activity of abdominal muscles (rectus abdominis and external oblique muscle) was assessed using surface EMG and normalized maximal voluntary isometric contraction (MVIC). The significance of differences between the sling exercise group and the swiss-ball exercise group was evaluated by the independent t-test. Results: These Results indicated that activities of rectus abdominis on right and left of the SEG during the curl up exercise were significantly greater than the SBEG. During the roll out exercise, activity of the abdominal muscle was not significantly different between the SEG and SBEG. In addition, during the jack knife exercise, activities of the right rectus abdominis and left external oblique muscle in the SEG were significantly greater than the SBEG. Conclusion: In conclusion, activity of the abdominal muscles was maximized when curl up and jack knife exercise were performed using the sling rather than the swiss-ball. Therefore, if increased activation of the abdominal muscle is the goal of an exercise program, curl up and jack knife exercises may be useful.

Sling exercise treatment(S-E-T) is a therapeutic exercise based on scientific studies for the purpose of treating musculoskeletal or neurological disorders thereby improving strength, endurance, and skills for sensory-motor integration. Exercise resistance and intensity can be modified in various ways by changing the length of rope, patient position, therapist's manual resistance, and using elastic rope. The therapist can also progress to successively higher levels of exercise resistance and intensity by changing the position of the hanging point: the subject of this article. In brief, there are three axial components in S-E-T; hanging point, motor axis, and suspension point. The hanging point can be changed in several ways in relation to the joint; axial, superior, inferior, medial, and posterior hanging points. The position of the hanging point affects the amount of load on agonist and antagonist muscles as well as on the range of motion. To create an advanced exercise program, selection of hanging point can be two-dimensional such as superior-lateral or anterior-medial. Therapists, therefore, can freely but carefully select the best hanging point based on the purpose of the exercise and their level of knowledge in S-E-T.

Purpose : The purpose of this study is to investigate the effect of core motion pattern on abdominal muscle thickness on unstable support surface using sling suspension system and to provide an effective exercise program for therapeutic rehabilitation in clinical practice. Methods : In this study, we used the flank exercise using a sling. It was intended for 21 healthy men and 9 healthy women. Before and after the exercise of the subjects, abdominal muscles (EO, IO, TrA the thickness of the muscle) was determined using a diagnostic ultrasonic apparatus. The period of exercise was 3 times a week for 6 weeks. The exercise for each group started with 3 sets per week and 1 set per week was added. A description of the method and attitude of each exercise is as follows. First, the push-up flank 's exercise position is to put both feet on the sling and hold the floor with both hands. Second, the side flank's exercise postures take the side flanks, while the two legs hang on the sling and one arm supports the body with an articulated bend (about $90^{\circ}$). Third, the elbow flank's exercise position is to put the two legs on the sling, and take a flank posture with the arms bent and joint bending (about $90^{\circ}$). Results : There was a significant difference in the thickness of the muscle in the three flank movements after the exercise (p<.05). The most significant difference was in the change of the muscle thickness in the abdominal muscle, the outer muscle, and the stomach in the elbow flank exercise after exercise. There was a significant difference between the mean thickness of the abdominal muscles according to the flank type after exercise (p<.05). Conclusion : In flank exercise for core stabilization using sling, it is considered effective to strengthen the abdominal muscles by considering the support surface, difficulty level, change of movement pattern.

Background: The purpose of this study was compare and analyze the flexibility and dynamic balance in adolescents with idiopathic scoliosis and provide scientific basis for effectively treating idiopathic scoliosis. Methods: The subjects of this study were 20 members of adolescences. To measure the flexibility of the spine, a left buckling instrument was used, and it was measured using a modified sit and reach test. They were randomly divided into core exercise with sling program group (n=10) and general exercise program group (n=10), each consisting 50 minutes each for 4 times per week for 8 weeks. Results: The results of the study are as follows. First, Both groups were increased statistically significantly in spinal flexibility but no significant differences have been found between the two groups after 8 weeks of exercise. Second, Both groups were increased statistically significantly in balance ability of dynamic foot pleasure ratio but no significant differences have been found between the two groups after 8 weeks of exercise. Conclusion: In summarizing the results of this study, sling exercise with core exercise was effective in the decrease of flexibility and stability than general scoliosis exercise in adolescents with idiopathic scoliosis. It is also believed to be applicable to spinal diseases caused by muscular weakness since it is effective in strengthening core muscle strength.

Purpose：The aim of this study was to determine the effect of active sling exercise on shoulder subluxation in hemiplegic patients. Methods：Twenty persons with shoulder subluxation were randomly divided into two groups; the experimental group(10 persons) and the control group(10 persons). Usual physical therapy and occupational therapy were applied in all groups in a day for 4 weeks. Additionally the experimental group was received 30 minutes sling active exercise (flexion, extention, adduction, abduction, intenal rotation, external rotation, horizontal adduction, horizontal abduction) for shoulder joint in a day for 4 weeks. I investigated the therapeutic effect of sling exercise through the Wolf motor function test (WMFT), Quantitative radiographic measurements and range of motion test at pre and post intervention period. Results：The passive range of motion was significantly increased in the experimental group compare with the control group. However, the active range of motion was no statistically significantly difference in both of the experimental and the control group. The level of WMFT was significantly decreased in the experimental group compared with control group. Although, there was no significantly difference the degree of the shoulder subluxation was more decreased in experimental group than control group. Conclusion：Taken together, these results suggest that sling exercise could be beneficial therapeutic method for hemiplegic shoulder. But to generalize it, more study and exercise program might be needed to confirm its availability.

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.
