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.
