Idiopathic scoliosis is a 3-dimensional deformity of the spine, with direct effects on the thoracic cage, characterized by the lateral displacement (greater than 10◦) and rotation of vertebral bodies during periods of rapid somatic growth.1 Adolescent idiopathic scoliosis (AIS) is found between the age of 10 and skeletal maturity2 and its prevalence is estimated at 2---4% in children between 10 and 16 years of age.2,3 This condition encompasses several complications including back pain, poor body image, and impaired pulmonary function.3 In fact, previous studies have shown a decreased pulmonary function in adolescents with idiopathic scoliosis,4 and an inverse correlation between scoliosis Cobb angles and pulmonary function.4 Adolescents with severe scoliosis, with Cobb angles above 45---50◦, are routinely managed with spinal fusion surgery.3 In addition to the mechanical restriction to ventilation, changes in spine and thoracic cage position may alterthe length ofrespiratory muscles influencing the ability to generate tension.
