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
Neuromechanics of idiopathic scoliosis scoliosis that appear after the age of 10 years, account for 89% of idiopathic scoliosis. From these statistics, it seems that individuals are at highest risk of developing idiopathic scoliosis during adolescence. Because scoliotic people have higher joint laxity compared to non-scoliotic people, they are drawn toward gymnastics but the practice of gymnastics for less than 20 hours training per week does not cause scoliosis. Based on populations that had more than 20 hours training per week, idiopathic scoliosis has been observed among 10% of tennis players, 16% of young swimmers and 24% in professional ballet companies.
