PURPOSE: Bridge exercises are broadly used to develop trunk co-activation patterns that promote spine stability. This study was to analyze the trunk muscle activity during bridge exercise with various shoulder support surface(stable, sling, Swiss ball). METHODS: The subjects were 20 healthy subjects in their twenties. Subjects were performed bridge exercise on 4 different shoulder support surfaces using stable and labile instruments. 1) Bridge exercise on a stable surface. 2) Bridge exercise with their shoulder on a stable bench. 3) Bridge exercise with their shoulder on a sling. 4) Bridge exercise with their shoulder on a Swiss ball. Rectus abdominis, erector spinae, internal oblique, external oblique muscle activities were measured using electromyography. RESULTS: There were significant differences in RA, EO muscles between performing each of the 4 exercises(p<.05). RA and EO was recorded the highest activity during the bridge exercise with their shoulder on a sling. The lowest activity was recorded during conventional supine bridge on a stable surface. There were no differences found for the EO/RA and IO/RA ratio. The EO/RA and IO/RA ratio was the highest in the bridge exercise with their shoulders resting on a stable bench. CONCLUSION: These findings suggest that change of shoulder support surface during bridge exercise may be useful for enhancing the trunk stability.

This study aimed to identify the effect of the push-up plus exercise with sling on the muscle activity and lung function in adults with forward head posture over a period of 8 weeks. A total of 16 adults with forward head posture were recruited. The participants were divided into two groups : control (n-=8) and experimental (n=8). From July 6 until Aug 28, 2015, the participants were instructed to perform the knee push-up plus exercise and knee push-up plus using sling exercise three times a week to begin with and progressing to three sets of push-ups on each occasion after 8 weeks. The participants in both groups showed an increase in their craniovertebral angle (both groups p<0.001) and a decrease in their crania rotation angle (control p<0.05, experimental p<0.001). The participants in both groups showed a decrease in their trapezius activity (both groups p<0.001), an increase in their serratus anterior and lower trapezius muscle activity (both groups p<0.001), (and an increase in their) lung function (control group p<0.01, experimental group p<0.001). These findings show that push-up plus exercise improves posture and increases activation of lung function, while the push-up plus exercise in the sling is more effective in improving the forward head posture. The push-up plus exercise in the sling was more effective in improving the forward head posture, but there was no significant difference in the lung function between the two groups. Therefore, the push-up plus exercise in the sling is recommended as an exercise that is effective for the improvement of the posture and lung function of persons with forward head posture.

Purpose: Breast surgeons usually insert tissue expander or implant beneath the subpectoral - subglandular dual plane in breast reconstruction. But sometimes it happens unsatisfactory lower pole fullness, asymmetric inframammary fold and breast shape because there is implant migration due to the pectoralis major muscle contraction and gravity. To solve all the problem like these, we introduce implant breast reconstruction using AlloDerm$^{(R)}$(LifeCell Corp., Branchburg, N.J.) sling. Methods: The AlloDerm$^{(R)}$ sling was used in 13 patients and 18 breasts for implant breast reconstruction. After mastectomy, costal and lower sternal insertion of pectoralis major muscle was detached. Rehydrated AlloDerm$^{(R)}$ was sutured to the chest wall and serratus anterior fascia at the level of inframammary fold downward and to lower border of the pectoralis major muscle upward like crescent shape with tension free technique after implant insertion into the subpectoral - subAlloDerm dual pocket. Results: We make satisfactory lower pole fullness, symmetric inframammary fold and breast shape. In conclusion, patients obtain relatively natural breast shape. There was no complication except one case of capsular contracture and one case of breast cellulitis. Conclusion: Implant breast reconstruction using AlloDerm$^{(R)}$ sling makes easy to get natural breast shape through satisfactory lower pole fullness, symmetric inframammary fold and implant positioning.

Background: A typical plank exercise (PE) strengthens the core muscles, stabilizes the spinal column, and provides stability around the pelvis and trunk when the trunk is aligned. However, because PE require that the hip joint be kept straight, they can activate the hamstring (HAM). Excessive HAM activation can induce tightness, which may cause low back pain. Therefore, it is necessary to explore PE methods that can minimize HAM activity while maximizing core muscle activity. Design: Cross-sectional study. Methods: This study included 30 healthy adults as subjects. We measured the activity of the HAM and the erector spinae (ES), rectus abdominis (RA), and external oblique (EO) muscles using surface electromyography during three PEs (typical PE, PE with balance pad, and PE with sling). Results: The RA, EO, and ES showed the highest muscular activity during PE with balance pad and the lowest during PE with sling; however, the differences were not significant. The HAM showed lower activity during PE with sling than during the other two PEs; however, these differences were also not significant. Conclusion: Although HAM activation was not significantly difference among PE positions, we should recognize altering activation of core and hamstring muscle according to PE postures.

Purpose This study is to investigate the effect of sling exercise on the balance capacity of spastic diplegia cerebral palsy patient based on Bobath concept. Methods A single subject experiment was designed targeting an 8year old child with the rigid bilateral cerebral palsy. The static balance test used the 30 second Rombug test of BT4, and the dynamic balance test used the timed up and go test. Results In the 30second Rombug test of BT4, the child had a smaller median outcome than baseline and withdrawal period. In the TUG test, the walking speed in the intervention period was improved comparing to the baseline and withdrawal period. Conclusion The sling exercise based on the Bobath concept has been proved that it is an effective intervention to improve the static and dynamic balance capacity of patients with rigid bilateral cerebral palsy.

Purpose: This study was conducted to investigate the effects on muscle thickness and balance ability after performing plank exercise on various surface types. Methods: In this study, there were thirty healthy participants. Participants were randomly distributed into three groups, a control group (n=10), sling group (n=10), and ball group (n=10). All participants performed plank exercises three times a week for four weeks. Plank exercises consisted of five sets of 30 seconds each with a one minute break between each set. Muscle thickness of the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) was measured using an ultrasound diagnostic apparatus and balance was measured using I-balance. Results: Evaluation of muscle thickness revealed that the IO and EO muscle of the ball group changed significantly relative to the control group (p<0.05). However, there were no significant changes in balance. Conclusion: The results revealed that performing plank exercise on a ball is more effective among various types of surfaces.

The Musculoskeletal Disease has been ignored or turned away due to the difficulty of diagnosis and the vagueness of judgement up to now. Contrary to other diseases, there were many cases where the character of the Musculoskeletal Disease wasn't revealed through the objective inspection. And that's because the Musculoskeletal Disease appears for the most part due to muscular defect so it is impossible to diagnose the muscle by X-ray diagnosing the bone and it is also impossible to diagnose the fine damage of the muscle or tendon even by advanced device like MRI. As the nervous blood vessels or acupunctures pass through or are next to the muscle, the tension of the muscle put pressure on these so can become the direct or indirect causes of various kinds of pains or intern diseases. But in spite of that, for lack of proper equipment diagnosing the state of the muscle(Shortened.. Relaxed... or Hardened...) the muscle has been disregarded or neglected intentionally or unintentionally. While many people think themselves to be a muscular expert, if they don't see the shape of the muscle, that is just like blind treatment. But as now the equipment diagnosing the state of the muscle is developed, it seems that this problem can be settled. It was attempted in this study that the muscle or skeleton of the Musculoskeletal disease patients was diagno the treatment order and method were decided by a questionnaire survey and simple inspection, and the Musculoskeletal correction exercise using the muscle management and sling system made them escape from the Musculoskeletal disease, turning their muscle into more flexible and stronger muscle. As a result notwithstanding the limited treatment period '12 times', the improvement rate was as high as 74%, which showed that the muscle management and Musculoskeletal correction exercise had a great effect on the symptom improvement of the patients. If the treatment times had increased, the improvement rate also would have increased more.

The purpose of this study was to investigate the effects of 8-week schroth 3-dimensional exercise and ball-sling complex exercise treatment on cobb's angle, abdominal muscle endurance, flexibility and balance in adolescents with idiopathic scoliosis. Thirty subjects with scoliosis were random assignment into one of two experimental groups, either schroth treatment(n=15) or ball-sling complex exercise treatment(n=15). Exercise program was to perform for 8-week and 90min and 3 times per week. The results of this study were as follows; First, cobb's angle was significantly decreased after 8-weeks in schroth treatment(p<.001). And also abdominal muscle endurance(p<.05), flexibility(p<.001) and balance(p<.001) were significantly improve in pre vs. post treatment. Second, the ratio of cobb's angle change was significantly higher in schroth treatment compared to ball-sling complex exercise treatment following 8-weeks(p<.05). These results suggest that although both the schroth treatment and bal-sling complex exercise treatment in adolescents with idiopathic scoliosis can improve on cobb's angle, abdominal muscle endurance, flexibility and balance, but schroth treatment was better than ball-sling complex exercise treatment improving effect of cobb's angle. Therefore, we consider that schroth treatment has more effect of prevention and therapy in idiopathic scoliosis in adolescents.

Dysfunction of the anterior and dorsal muscles of the trunk have been studied in relation to low back pain of many years. Many muscles of the trunk are capable of contributing to the stabilization and protection of the lumbar spine, recent evidence has suggested that transversus abdominis may be critically involved and has been the focus of rehabilitation. The delay in onset of contraction of trunk muscles associated with movement of the upper or lower limb in patients with low back pain indicates a significant deficit in the automatic motor command for control of disturbance to the spine. The function of transversus abdominis has been largely ignored in the evaluation of spinal stabilization and protection. The most essential stabilizing muscles for the lumbar column are the transversus abdominis and the multifidus. Sling exercise therapy(SET) concept consists of a system of diagnosis and treatment. The system of diagnosis involves testing the muscle's tolerance through progressive loading in open and close kinetic chains. The SET system contains elements such as relaxation, increasing the range of movement, traction, training the stabilizing musculature, sensorimotor exercises, training in open and close kinetic chains, dynamic training of the mobilizing musculature, cardiovasc+ular exercises, group exercise, personal exercise at home. Sensorimotor training is an essential element of the SET concept. The emphasis is on closed kinetic chain exercises on an unstable surface, thereby achieving optimum stimulation of the sensorimotor apparatus.
