A clinical trial investigated the effectiveness of a combination treatment for adolescent idiopathic scoliosis that combined a flexible brace with two weeks of balanced cupping therapy. The study included adolescents with idiopathic scoliosis divided into a control group (brace only) and an observation group (brace plus cupping therapy) from October 2022 to September 2024. After three months, the observation group showed a significantly greater reduction in Cobb angle (24.16 ± 3.25 degrees versus 26.98 ± 3.87 degrees) and apical transverse rotation. Plantar pressure improved more significantly in the observed group, while the index of central deviation of pressure reached the value of 8.87 ± 2.17 compared to 10.54 ± 2.21 in the control group. The combined treatment showed a better safety profile (8.00% adverse events versus 14.46%) and a significantly better quality of life. The results suggest a potential clinical benefit of combined treatment, but the authors emphasize the need for long-term studies to verify the lasting effects of this treatment method.
