Abstract Objective  Adolescent idiopathic scoliosis is the most prevalent type of scoliosis, and its consequences on the human torso have not been deeply studied. In spite of being a 3D condition, clinical management is circumscribed to 2D images among health-care professionals. GMM is a well-recognized tool in the study of 3D shape and symmetry. Methods  Twenty-four subjects with AIS and 24 controls were subjected to surface scan. Digitization and shape data were extracted and submitted to GMM analysis. 3D shape and asymmetry were correlated with Cobb angle in subjects with X-ray availability. Comparisons of mean shapes were done between each group and its symmetric average shape and between each group at two states: initial and 6 months after. Results  AIS and controls show similar areas of asymmetry, being significantly higher in quantity in AIS (PD = 0.045; PD 0.037; p
