Non-surgical options for the treatment of adolescent idiopathic scoliosis (AIS) include; physiotherapy, exercise, electrical stimulation and the use of braces. Among these, brace therapy is the only option that has objectively proven effectiveness and can change the natural history of the disease, and can reduce the requirement for surgery by stopping the progression of the scoliotic curvature. Therefore, the use of braces is an indispensable choice in patients who are suitable for the treatment of AIS. While only observation is recommended for mild curves, brace treatment should be considered as the first choice for curves between 20-45°. The aim of brace treatment is to halt the progression of the curvature during the child`s growing process, to improve the cosmetic appearance and to provide the whole body balance. There must be sufficient residual growth capability for brace therapy to exert its corrective effect. Permanent correction can be achieved by providing symmetrical growth with remodeling of the vertebrae. The brace should be custom made for the patient and should be easy to wear. At the beginning of the treatment, the prediction of progression must be well evaluated and unnecessary brace treatment should be avoided. The patient should be followed carefully, encouraged in terms of compliance to the treatment and attention should be paid to the prescribed periods. Patient compliance and continuation of treatment are the main keys to success.
