Active self-correction and maintenance of the improved posture during functional activities are two primary goals of the Schroth method.
A recent study by Marco Monticone, Emilia Ambrosini, Daniele Cazzaniga, Barbara Rocca and Simona Ferrante published in the European Spine Journal titled “Active self-correction and task orientated exercises reduce spinal deformity and improve quality of life in subjects with mild adolescent idiopathic scoliosis. Results of a randomized controlled trial” concluded that “The programme of active self-correction and task-oriented exercises was superior to traditional exercises in reducing spinal deformities and enhancing the HRQL in patients with mild AIS. The effects lasted for at least 1 year after the intervention ended”. Read more here.
This is a very high quality research paper looking specifically at the difference between this type of scoliosis specific exercise and traditional physio exercise for scoliosis, on Cobb angle and on Quality of Life.
