Idiopathic scoliosis is a developmental deformation of the spine and the trunk, which significantly influences the form and function of a young organism. The extensive interest of medical experts in the treatment of spinal deformities results from the incidence of such disorders in the adolescent population (2-3%), health consequences of the disease progression as well as social and economic costs [
1‐
4]. On the other hand, the health related quality of life of the adults with mild to moderate idiopathic scoliosis, including individuals conservatively treated in adolescence, seems very good [
5‐
7]. Bracing and physiotherapy are the non-surgical methods of treatment practiced for mild to moderate scoliosis. The aim of brace treatment is to stop deterioration of the deformity, which is a natural history of progressive scoliosis beyond 25 degrees in immature adolescents. Within the group of rigid Thoraco-Lumbo-Sacral Orthoses (TLSO), the Cheneau brace is most widely used in Poland. The major mechanism of this orthosis consists of correcting three-dimensional deformity of the spine and the trunk by a system of multipoint pressure zones and expansion chambers [

9]. Studies carried out so far have shown that wearing a brace changes the natural history of scoliosis and probably helps the patient to avoid surgical procedure [
10‐
12], especially if the brace follows current quality standards [
13]. One meta-analysis has shown that bracing is an effective therapeutic method for idiopathic scoliosis [
14]. In 2005 a systematic review of literature was carried out focusing on evaluating the effectiveness of conservative treatment methods for scoliosis, including bracing [
15]. Out of 436 articles only 3 discussed randomized studies and 10 included a control group. However, only 5 referred to bracing. A comparison of a brace treated group with a control group showed a significant superiority of bracing [
16]. Another study on the effectiveness of bracing (Milwaukee) as a supplementary treatment for exercising did not show therapeutic effect; the results of both groups did not differ statistically [
17]. A comparison of bracing with exercises did not show difference between the groups [
18]. However, a comparison of bracing with electrostimulation showed a higher effectiveness of the former therapy [
19]. A comparison of various braces (Charleston Bending Brace, Milwaukee) did not reveal a significant advantage of any of them [
20‐
22]. Finally, recent Cochrane Database of Systematic Reviews publication revealed a low quality evidence in favour of using bracing [
