It is known that adolescent idiopathic scoliosis (AIS) is often accompanied by balance deficits. This reciprocal relationship must be taken into account when prescribing new therapeutic modalities because they may differently affect postural control interacting with therapy and influencing its results. The purpose was to assess the effects of wearing a Chêneau brace (BRA) or performing active self-correction (ASC) movements on postural control in nine female adolescents with AIS. .
