Neuromechanics of idiopathic scoliosis all rachis ranges of motion decrease because of surgery but hips extension range of motion is comparable to the one of non-operated scoliotic people. In terms of gait, while walking at a constant speed of 4 km/h for a few minutes until a steady state is reached, relative to non-scoliotic people, idiopathic scoliotic people have a frontal (i.e. coronal) pelvis, hip, and shoulder, transversal hip and sagittal knee motion restriction. The step length is reduced and the stance phase duration is also reduced. Surgical treatment of thoracolumbar/lumbar adolescent idiopathic scoliosis, whether performed with anterior spinal fusion or posterior spinal fusion
Management of scoliosis of bracing has not been definitively demonstrated in randomised clinical studies, with more limited studies giving inconsistent conclusions. In 2013 the Bracing in Adolescent Idiopathic Scoliosis Trial (BrAIST) published results establishing benefits of bracing in adolescents with idiopathic scoliosis. In the randomized cohort, 72% in the group instructed to wear a brace for 18 hours per day against 48% in the observation group sustained curve progression to under 50 degrees, the proxy used for not requiring surgery. Additionally results suggested that the more a patient wore the brace, the better the result. In progressive infantile and sometimes juvenile scoliosis, a
