Abstract.[Purpose] The object of this study was to examine the effects of the core muscle release technique (CRT) on correcting scoliosis.[Subjects] Ninety patients diagnosed with scoliosis participated in this study. [Methods] First, participants were divided into three groups according to method of treatment. The first group was administered 50 minutes of CRT five times a week for two weeks. The second group performed general exercise to treat scoliosis for the same duration. The third group received electrotherapy in 50-minute sessions, five times a week for two weeks. The CRT began with release treatment of the diaphragm, and then focused on control of paraspinal muscle tone. Respiratory therapy was also conducted during these treatments. Directly after their two-week treatment, the patients were re-examined, and another follow-up test was performed two weeks after treatment had finished.[Results] The data suggest that CRT, exercise and electrotherapy all helped to decrease the Cobb angle. Of these treatment methods, however, CRT was the most effective for the treatment of scoliosis. [Conclusion] CRT was effective in the correction of scoliosis.

[Purpose] This research investigated the effect of angular variation of flexion of the elbow joint on the muscle activation of elbow flexor muscles. [Subjects] The research subjects were 24 male college students with a dominant right hand who had no surgical or neurological disorders and gave their prior written consent to participation with full knowledge of the method and purpose of this study. [Methods] The subjects' shoulder joints stayed in the resting position, and the elbow joint was positioned at angles of 55°, 70°, and 90°. The angle between the pulley with weights and forearm stayed at 90°. Surface electromyography was used to measure muscle activities. Three measurements were made at each elbow angle, and every time the angle changed, two minutes rest was given. [Result] The muscle activities of the elbow flexors showed significant changes with change in the elbow joint angle, except for the biceps brachii activities between the angles of 55° and 70° of elbow flexion. The muscle activities of the biceps brachii and brachioradialis showed angle-related changes in the order of 55°, which showed the biggest value, followed by 70° and 90°. [Conclusion] In order to improve muscle strength of the elbow flexor using a pulley system, it seems more effective to have a 90° angle between the pulley with weights and the forearm when the muscle is stretched to a length 20% greater than its resting position.
