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
Scoliosis disease, but whether it changes quality of life, appearance, or back pain is unclear. Surgery is usually recommended by orthopedists for curves with a high likelihood of progression (i.e., greater than 45 to 50° of magnitude), curves that would be cosmetically unacceptable as an adult, curves in patients with spina bifida and cerebral palsy that interfere with sitting and care, and curves that affect physiological functions such as breathing. Surgery is indicated by the Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) at 45 to 50° and by the Scoliosis Research Society (SRS) at a Cobb angle of 45°. SOSORT
